This is an appeal against conviction.
Following a trial, Matthew Donald Tilley, the appellant, was found guilty of the murder of
Mrs Suzanne Poll on 29 April 1993. The appellant was not arrested and charged with the offence
until 21 September 2019. The trial commenced in November 2021.
The prosecution alleged that the appellant attended the Sands and McDougall newsagency located at
Parabanks Shopping Complex in Salisbury (‘the newsagency’) on the evening of 29 April 1993 and
stabbed Mrs Poll to death in the rear office of the store. There was no apparent motive for the offence.
-- 1 of 90 --
There was no dispute that the offender stabbed Mrs Poll multiple times with the requisite intention
to commit murder. The central issue in dispute at trial was identity. The prosecution case was wholly
circumstantial and based primarily on DNA evidence which supported the proposition that the
appellant was a contributor to multiple blood stains located at the crime scene. The prosecution
alleged that in the course of the attack the appellant sustained a free-bleeding injury which caused
him to deposit blood at various locations between the rear office of the newsagency (where Mrs Poll's
body was found) and the sole point of entry/exit to the store.
The appellant did not give or call any evidence at the trial. Defence counsel challenged the accuracy
and reliability of the DNA evidence; and contended that evidence adduced as part of the prosecution
case raised a reasonable doubt as to whether the prosecution had proved the appellant was the
offender.
The appellant now appeals against the conviction on the following, consolidated, grounds:
1. The trial Judge erred as a matter of law in his directions to the jury in relation to the absence
of motive, inter alia, in that his Honour erroneously directed the jury that the prosecution did
not have to prove motive because, in a case such as the present, ‘they would not know what
it was themselves’ and ‘that it was a responsible position to take’.
2. The trial Judge erred in his directions to the jury as to the forensic evidence by failing to direct
the jury that before they could rely on the forensic results, they must be satisfied beyond
reasonable doubt that: the chain of evidence was established; and the risk of contamination
was excluded.
2A. The trial Judge erred as a matter of law in admitting the evidence of the DNA results.
2A.1 The trial Judge erred in failing to provide any, or adequate, reasons for his ruling that
the DNA evidence was admissible and/or, alternatively, in declining to exclude the
evidence in the exercise of his discretion.
2A.2 The trial Judge erred in failing to find that the DNA evidence implicating the appellant
was obtained in breach of the provisions of the Criminal Law (Forensic Procedures)
Act 2007 (SA) (‘the CLFPA’).
Alternatively, the trial Judge ought to have excluded the DNA results in the exercise
of his discretion as a result of the alleged breaches of the CLFPA and in the purported
absence of authority to conduct familial searching, together with the unlawful and/or
unfair circumstances in which police obtained the appellant’s DNA sample.
2A.3 The trial Judge erred in failing to find that the methodology and circumstances relating
to obtaining the appellant’s DNA sample were unlawful, unfair and/or not authorised
by the CLFPA.
Alternatively, the trial Judge ought to have exercised his discretion to exclude the DNA
evidence as a result of the unlawful conduct and/or unfairness arising from the
circumstances in which police obtained the sample of the appellant’s DNA.
2A.4 In relation to the alleged crime scene samples, the prosecution could not establish
beyond reasonable doubt proof of the chain of evidence nor exclude the risk of
contamination.
3. The trial Judge erred in his directions as to the evidence of M.
3.1. The trial Judge erred by failing to direct the jury as to the exculpatory use they could
make of the evidence if they found that the appellant's statements were referable to
Mrs Poll and true.
3.2. The trial Judge erred by failing to direct the jury that they must find proved beyond
reasonable doubt that the appellant's statements were referable to the deceased before
they could use them as evidence of lies.
-- 2 of 90 --
3.3. The trial Judge’s directions were flawed in so far as they constituted a lies direction.
3.4. The trial Judge erred by failing to adequately present the defence case in relation to
such statements.
3A. The trial Judge erred as a matter of law in admitting the evidence of M for the purposes
contended by the prosecution. Alternatively, the trial Judge erred by failing to exclude the
evidence of M in the exercise of his discretion.
4. The trial Judge erred in his directions as to the burden and standard of proof, and in failing to
adequately and fairly present the defence case.
4.1. The trial Judge erred by failing to adequately direct the jury that the prosecution must
exclude the reasonable possibility that the appellant did not kill the deceased.
4.2. The trial Judge erred by failing to adequately put the defence case as to the forensic
evidence and M’s evidence, and interspersed his presentation of the defence address
with rebuttal comments.
4A. The fair trial of the appellant miscarried as a result of the unbalanced summing up of the trial
Judge.
5. The trial Judge erred by directing the jury that the evidence of Ms Deborah Parsons and the
evidence of Dr Sara Jones (the shoe print evidence) was ‘consistent with’, and confirmatory
of, the prosecution case.
6. The fair trial of the appellant miscarried as a result of the admission of the evidence of
Dr Ross James that it was possible that the offender had suffered a cut during the attack
causing a free-bleeding injury, and of Sergeant David Veldhoen as to a free-bleeding injury
being responsible for various blood deposits located at the crime scene.
Permission to appeal on Grounds 2, 3.1, 3.4 and 4 was granted and the question of permission in
relation to the balance of the remaining grounds was referred to this Court for consideration.
Held, per the Court, granting permission to appeal on Grounds 3.2, 3.3, 3A and 4A but refusing
permission to appeal on the remaining Grounds and dismissing the appeal:
1. The trial Judge’s directions as to motive were not inadequate. His Honour made clear that
motive, or the absence of motive, for the appellant to commit the offence was a factor the jury
could take into account when determining whether the prosecution had proved the appellant’s
guilt beyond reasonable doubt.
2. The trial Judge did not err in admitting the blood and DNA deposition evidence, nor were his
directions in relation to that evidence inadequate such that there was a miscarriage of justice.
His Honour expressly linked the requirement for the prosecution to prove the blood and DNA
deposition evidence beyond reasonable doubt to an acceptance of the accuracy and reliability
of the evidence, which was directly informed by reference to proof of the chain of evidence
and the exclusion of the risk of contamination of the crime scene samples.
3. Notwithstanding the express strictures within the CLFPA as to what will constitute an
impermissible use of the database, a plain reading of the Act permits the scientific processes
which were conducted in this case; they were not unlawful.
4. The CLFPA regulates the performance of forensic procedures on a person’s body but does not
go so far as to codify the manner in which police are required to obtain all forensic samples,
nor does it apply to a forensic procedure authorised under another law of this State or a search
of a person. In this case, the provisions of the CLFPA were not engaged by the police conduct
in seizing the appellant’s discarded coffee cup. This conduct did not constitute a ‘forensic
procedure’ for the purposes of the CLFPA in that it did not involve taking a sample, or other
material, from a person’s body. Accordingly, the mechanism by which police obtained the
-- 3 of 90 --
appellant’s DNA profile was not unlawful or improper such as to give rise to the
Bunning v Cross discretion.
5. There was sufficient evidence before the jury capable of establishing beyond reasonable doubt
both the chain of evidence and excluding the risk of contamination. In any event, the issue of
whether those matters were proven beyond reasonable doubt was a question of weight rather
than admissibility.
6. The evidence of M was admissible, and the trial Judge did not err in declining to exclude it in
the exercise of his discretion.
7. There was no miscarriage of justice occasioned by the trial Judge’s directions on lies.
8. In summing up, the trial Judge outlined the standard and burden of proof in orthodox terms.
Those matters were reiterated when his Honour came to discuss the elements of the offence
of murder and when instructing the jury on circumstantial evidence. The trial Judge did not
err in his directions as to the burden and standard of proof.
9. When considered in its entirety, the trial Judge’s summing up was not unbalanced and his
Honour’s remarks were not apt to create a substantial risk that the jury might actually be
persuaded of the appellant’s guilt. Nor did his Honour fail to adequately and fairly present the
defence case.
10. The evidence of Ms Parsons and Dr Jones were minor strands of the circumstantial case
against the appellant. The trial Judge’s directions in relation to those bodies of evidence did
not elevate the evidence beyond what it could properly establish as part of the prosecution
case and were not erroneous; there was no risk that the jury would approach that evidence as
directly implicating the appellant.
11. The authority of R v B and D (1993) 66 A Crim R 192 does not stand for the proposition that
it is improper or misleading for a trial Judge to use the terms ‘consistent with’ in relation to
strands of circumstantial evidence which, of themselves, do not necessarily implicate the
accused.
12. The evidence of Dr James was not speculative, nor extend beyond his specialised knowledge
or field of expertise. The evidence was not inadmissible.
13. The evidence of Sergeant Veldhoen was within his established expertise as to blood pattern
analysis and was admissible as expert evidence.

TILLEY v THE KING
[2023] SASCA 80
Court of Appeal – Criminal: Livesey P, David JA and Buss AJA
1 THE COURT: After a trial before a jury, the appellant, Matthew Tilley, was found
guilty of the offence of murder. He was alleged to have murdered Mrs Suzanne
Poll (‘Mrs Poll’) by stabbing her to death on 29 April 1993, when he was 21 years
old. The appellant was not arrested and charged with the offence until
21 September 2019. The trial commenced in November 2021.
2 The prosecution alleged that the appellant attended a newsagency store,
Sands and McDougall, located at the Parabanks Shopping Complex in Salisbury
(‘the newsagency’), where Mrs Poll worked as a shop assistant. At around 9:00pm
on 29 April 1993, shortly before closing time, the appellant allegedly violently
attacked Mrs Poll in the rear office of the store, stabbing her to death with a knife.
Mrs Poll’s cause of death was ultimately attributed to rapid blood loss caused by
multiple stab wounds. There was no apparent motive for the offence.
3 The central issue at trial was identity. The prosecution case was wholly
circumstantial and based primarily on DNA results extracted from multiple
samples of blood-like stains located at the newsagency. The prosecution alleged
that the offender sustained a free-bleeding injury during the attack and,
consequently, deposited blood at various locations between the rear office, where
Mrs Poll’s body was found, and the sole point of entry to, or exit from the store.
Forensic evidence supported the proposition that the appellant was a contributor
to blood- like samples taken from Mrs Poll’s cardigan, her right shoe, a plastic cup
holding receipts, a State Bank envelope, and a Commonwealth Bank envelope.
4 The appellant did not give or call any evidence at trial. Defence counsel
challenged the accuracy and reliability of the DNA evidence on two bases: first,
that the chain of evidence relating to the blood samples was incomplete; and
second, that the risk of contamination of the blood samples could not be excluded
beyond reasonable doubt. It was submitted that the DNA results could not be relied
on due to the imperfections in police crime scene examination processes, evidence
collection techniques, exhibit recording, and the possibility of errors in forensic
laboratory processes and record keeping.
5 At trial, defence counsel contended that there was evidence adduced as part
of the prosecution case which raised a reasonable doubt as to whether the
prosecution had proved the appellant was the offender. That evidence included:
• fingerprints on Mrs Poll’s handbag (which appeared to have been rifled
through) which did not match the appellant’s fingerprints;
• DNA evidence that the appellant was not a contributor to samples taken
from beneath Mrs Poll’s fingernails;
-- 5 of 90 --
[2023] SASCA 80 The Court
2
• witness’ evidence of other males observed in, or near, the newsagency
at the relevant time who had an appearance inconsistent with the
appellant’s appearance;
• the lack of injuries or cuts observed on the appellant (inconsistent with
the prosecution case that he had sustained a free-bleeding injury during
the alleged attack);
• the significant forensic disadvantage occasioned to the appellant by
reason of the passage of time which precluded his ability to access work
records which may otherwise have given him an alibi; and
• the absence of any known motive.
6 In recorded telephone calls, the appellant denied having committed the
murder and said that he was not there when Mrs Poll was killed, nor did he have
any knowledge of who committed the murder.
7 There was no contest as to the cause of death. Nor was it in dispute that the
offender stabbed Mrs Poll multiple times with the requisite intention to commit
murder. The contested issue at trial was whether the prosecution had proved the
appellant was the offender; in other words, the identity of the offender.
8 The appellant now appeals against his conviction on the following
(consolidated) grounds:
1. The trial Judge erred as a matter of law in his directions to the jury in
relation to the absence of motive, inter alia, in that his Honour directed
the jury that the prosecution did not have to prove motive because, in a
case such as the present, ‘they would not know what it was themselves’
and ‘that it was a responsible position to take’.
2. The trial Judge erred in his directions to the jury as to the forensic
evidence by failing to direct the jury that, before they could rely on the
forensic results, they must be satisfied that the chain of evidence was
established beyond reasonable doubt; and the risk of contamination was
excluded beyond reasonable doubt.
2A. The trial Judge erred as a matter of law in admitting the evidence of the
DNA results.
Particulars
2A.1 The trial Judge erred in failing to provide any, or adequate, reasons
for his ruling that the DNA evidence was admissible and/or,
alternatively, in declining to exclude the evidence in the exercise
of his discretion;
-- 6 of 90 --
[2023] SASCA 80 The Court
3
2A.2 The trial Judge erred in failing to find that the DNA evidence
implicating the appellant was obtained in breach of the provisions
of the Criminal Law (Forensic Procedures) Act 2007 (SA) (‘the
‘CLFPA’) and, in particular, that the use of ‘familial searching’
was authorised by the CLFPA.
Alternatively, the trial Judge ought to have excluded the DNA
results in the exercise of his discretion as a result of the breaches
of the CLFPA and the absence of authority to conduct familial
testing, together with the unlawful and/or unfair circumstances in
which police obtained a sample of the appellant’s DNA.
2A.3 The trial Judge erred in failing to find that the methodology and
circumstances relating to obtaining a sample of the appellant’s
DNA were unlawful, unfair and/or not authorised by the CLFPA.
Alternatively, the trial Judge ought to have exercised his
discretion to exclude the DNA evidence as a result of the unlawful
conduct and/or unfairness arising from the circumstances in which
police obtained the sample of the appellant’s DNA.
2A.4 In relation to the alleged crime scene samples, the prosecution
could not establish the chain of evidence nor exclude the risk of
contamination, beyond reasonable doubt.
3. The trial Judge erred in his directions as to the evidence of M.
Particulars
3.1 The trial Judge erred by failing to direct the jury as to the
exculpatory use they could make of the evidence if they found that
the statements referred to Mrs Poll and were true.
3.2 The trial Judge erred by failing to direct the jury as to the need to
make a finding beyond reasonable doubt that they were referable
to Mrs Poll before they could use them as evidence of lies.
3.3 The trial Judge’s directions were flawed in so far as they
constituted a lies direction.
3.4 The trial Judge erred by failing to adequately present the defence
case in relation to such statements.
3A. The trial Judge erred as a matter of law in admitting the evidence of M
for the purposes contended by the prosecution. Alternatively, the trial
Judge erred by failing to exclude the evidence of M in the exercise of
his discretion.

4. The trial Judge erred in his directions as to the burden and standard of
proof, and in failing to adequately and fairly present the defence case.
Particulars
4.1 The trial Judge erred by failing to adequately direct the jury that
the prosecution must exclude the reasonable possibility that the
appellant did not kill Mrs Poll.
4.2 The trial Judge erred by failing to adequately put the defence case
as to the forensic evidence and M’s evidence and interspersed the
presentation of the summary of the defence address with rebuttal
comments.
4A. The fair trial of the appellant miscarried as a result of the unbalanced
summing up of the trial Judge.
5. The trial Judge erred by directing the jury that the evidence of
Ms Deborah Parsons, and the shoe print evidence, was consistent with,
and confirmatory of, the prosecution case.
6. The fair trial of the appellant miscarried as a result of the admission of
the evidence of Dr Ross James that it was possible that the offender had
suffered a cut during the attack causing a free-bleeding injury, and of
Sergeant David Veldhoen as to a free-bleeding injury being responsible
for various blood deposits located at the crime scene.
9 Permission to appeal on Grounds 2, 3.1, 3.4 and 4 was granted and the
question of permission to appeal on the balance of the remaining grounds was
referred to this Court for consideration.
Overview of the evidence
10 The prosecution case was that Mrs Poll had been stabbed to death at about
9:00pm on Thursday, 29 April 1993, while she was working alone in the
newsagency. There were no eyewitnesses to the stabbing. The weapon used in
the attack was never recovered by police. At the time of the discovery of Mrs Poll’s
body, the store cash register draw was open and almost empty, and Mrs Poll’s
handbag had the appearance of having been rifled through, thus raising the
possibility that her death was connected to a robbery.
11 Mrs Poll was last seen alive at about 8:55pm by witnesses Lisa Watts
(a co-worker) and Ms Watts’ husband, Anthony Watts. Mrs Poll’s body was found
at about 10:00pm by her husband, Darryl Poll, who attended at the store after she
failed to return home by the expected time. Thus, the prosecution placed the timing
of her death at between 8:55pm and 10:00pm.
12 Mrs Poll had been stabbed to death in a small staff-only office area located
at the rear of the store behind the main service counter. Her body was found lying
-- 8 of 90 --
[2023] SASCA 80 The Court
5
face-up on the floor and her handbag was nearby. The office door appeared to
have been recently damaged as a result of the bottom part being pulled away from
its frame with considerable force.
13 There was no dispute that the cause of death was haemorrhaging due to 18
stab wounds to the back, six of which penetrated so deeply that they exited through
the front of Mrs Poll’s chest cavity and abdomen. There were also incised wounds
to both hands, areas of the back, and the left side of her scalp, consistent with
defensive wounds. Based upon the physical characteristics of the stab wounds, a
forensic pathologist, Dr Ross James, concluded that a strong-bladed knife at least
22cm long had been used to inflict the wounds.
14 By reason of the nature and severity of the knife attack, ‘the large spillage of
blood at the crime scene’, and the likely size and sharpness of the knife used in the
attack; the prosecution alleged that the offender had sustained a free-bleeding
injury whilst stabbing Mrs Poll.
15 There was a pool of blood on the floor under, and around, the body of
Mrs Poll which, if trodden in, could have accounted for the presence of shoe
impressions in the rear office and main shop area leading to the single point of
entry to, and exit from the shop. The shoes worn by the first police officer on the
scene, Mr Poll, and the only ambulance officer to go into the office area, were
provided to forensic examiners and were accounted for amongst the shoe marks,
thus leaving a number of unidentified shoe marks at points located between Mrs
Poll’s body and the shop door. The shoe prints appeared to follow a path from the
inside of the office to the shop door consistent with the departure route of the
injured, free-bleeding offender after the attack. At the time of his arrest in
September 2019, a men’s size nine shoe was the optimum fit for the appellant. The
unaccounted shoe impressions were within that same size range.
16 The prosecution case was that the DNA evidence supported a conclusion that
the appellant had deposited his blood (from a free-bleeding injury sustained during
the attack on Mrs Poll) at various locations in the shop including: where Mrs Poll
was stabbed in the rear office; on her handbag (which appeared to have been rifled
through); around the shop in a general pathway leading from the rear office through
the entry/exit door; and on and around the entry/exit door.
17 The samples which the prosecution relied upon as providing evidence of the
appellant’s blood at the crime scene were as follows:
Exit door samples
(a) Stain on the lintel (SAM1):
There was a stain on the lintel which appeared to be a ‘drip stain’, that
being a stain caused by blood falling under gravity at approximately 90
degrees and striking the surface below. In 1993, the stain gave a
presumptive positive result for blood. A sample from the stain gave a
-- 9 of 90 --
[2023] SASCA 80 The Court
6
single source DNA profile with a likelihood ratio of greater than 100
billion in favour of obtaining the profile if the appellant was a
contributor to the sample than if he was not.
(b) Stain on floormat inside the entrance of the store (SAM2):
There were three spots of blood on the vinyl floor mat inside the sole
point of entry/exit to the store which had the appearance of drip stains.
In 1993, the stain gave a presumptive positive result for blood. A
sample from the stains gave a single source DNA profile with a
likelihood ratio of greater than 100 billion in favour of obtaining the
profile if the appellant was a contributor to the sample than if he was
not.
(c) The interior door handle (GDB1.1):
There was an apparent run of blood on the interior door handle which
consisted of a transfer stain – that is, a stain caused by a bloodied object
having come into contact with the door handle thus transferring a
volume of blood onto it – which then ran down the handle under the
force of gravity and caused a flow pattern. In 1993, the stain gave a
presumptive positive result for blood. The sample gave a mixed DNA
profile from two contributors with a calculated likelihood of 22 billion
in favour of obtaining the profile if the appellant was a contributor to
the sample rather than if he was not.
Office samples
(d) The damaged office door (SAM13):
There was a stain on the damaged office door which appeared to be a
drip stain in that it had dropped onto the horizontal surface of the door
and created a downward flow pattern under the force of gravity before
something wiped across it from the inside of the office to the outside.
In 1993, the stain gave a presumptive positive result for blood. The
sample gave a mixed DNA profile from two contributors with a
calculated likelihood of greater than 100 billion in favour of obtaining
the profile if the appellant was a contributor to the sample rather than if
he was not.
(e) Mrs Poll’s cardigan (SAM15.B):
There was a stain detected on the front lower right sleeve of Mrs Poll’s
cardigan which was located on the rear office floor. A cutting was taken
from the stain which gave a mixed DNA profile from two contributors.
There was a likelihood ratio of greater than 100 billion in favour of
obtaining the profile if the appellant was a contributor to the profile than
-- 10 of 90 --
[2023] SASCA 80 The Court
7
if he was not, and a likelihood ratio of 880,000 in favour of the inclusion
of Mrs Poll.
(f) Mrs Poll’s right shoe (SAM16.A):
There was a swab taken from the outer aspect of the sole of Mrs Poll’s
right shoe which was loose on the rear office floor. It gave a mixed
DNA profile from two contributors with a calculated likelihood of
greater than 100 billion in favour of obtaining the profile if the appellant
was a contributor than if he was not. Statistical weightings were
calculated in favour of the exclusion of Mrs Poll and Mr Poll as
contributors to the mixture.
Handbag samples
(g) Commonwealth Bank envelope (JPH1.3.A):
There was apparent blood-like smearing on the front of a
Commonwealth Bank envelope. The smearing gave a mixed DNA
profile from two contributors for which there was a likelihood ratio of
greater than 100 billion in favour of obtaining the profile if the appellant
was a contributor than if he was not; and a likelihood ratio of 2,300 in
favour of the inclusion of Mrs Poll.
(h) State Bank envelope (JPH1.4.A):
There was apparent blood-like smearing on the edges of paper inside a
State Bank envelope which gave a presumptive positive result for
blood. This gave a mixed DNA profile from two contributors for which
there was a likelihood ratio of 40 billion in favour of obtaining the
profile if the appellant was a contributor than if he was not; and 680 in
favour of the inclusion of Mrs Poll.
(i) Plastic holder (JPH1.6.A):
There was a stain approximately 20mm x 5mm in size located in the
corner of a plastic holder containing receipts and paperwork which gave
a presumptive positive result for blood. In 1993, the stain gave a single
source DNA profile with a calculated likelihood ratio of greater than
100 billion in favour of obtaining the profile if the appellant was a
contributor than if he was not.
18 Sergeant David Veldhoen, a blood stain pattern analyst, gave evidence that
the entry/exit door samples could have been made by a person with a free-bleeding
injury grabbing hold of the door handle, the pressure of which would cause blood
to expel from the hand, thereby creating the flow pattern (GDB1.1), and when
releasing that hold, causing individual blood drops to form and strike the ground
(SAM1, SAM2).
-- 11 of 90 --
[2023] SASCA 80 The Court

19 On the prosecution case, the DNA results supported a conclusion that the
appellant’s blood had been deposited at various positions in the newsagency during
the course of, and in connection with, his attack on Mrs Poll. The crime scene
evidence, blood pattern analysis, and DNA results (referred to by the trial Judge
compendiously as the ‘blood and DNA deposition evidence’) were the primary
pieces of circumstantial evidence against the appellant.
20 It was common ground between the parties that proof of the accuracy and
reliability of the blood and DNA deposition evidence was an ‘indispensable link’
in proof of the offence and therefore needed to be proved beyond reasonable doubt.
Other circumstantial evidence
21 In addition to the blood and DNA deposition evidence, the prosecution relied
on other pieces of circumstantial evidence to support their case that the appellant
was the offender.
Appellant’s mother lived in the area
22 The appellant made a number of formal admissions at the trial pursuant to
s 34 of the Evidence Act 1929 (SA). The admissions included that:
(a) in April 1993, the appellant's mother, Ms Mary Richardson, resided at
a house at Lawrie Avenue, Salisbury;
(b) on 26 October 1992, the appellant reported the theft of his backpack to
police and stated that his home address was his mother's house at
Lawrie Avenue, Salisbury; and
(c) Department of Infrastructure and Transport records showed that on
26 May 1993 the appellant reported that his residential address was his
mother's house at Lawrie Avenue, Salisbury.
23 From those admitted facts, the prosecution alleged that in 1993 the
appellant’s mother lived in a house at Lawrie Avenue in Salisbury, which was on
the opposite side of the Salisbury railway line to the Parabanks Shopping Centre.
The appellant lived with her, at this address, until sometime just before June 1993.
Ms Richardson gave evidence that after moving out, the appellant continued to
visit her at her home at least once a fortnight. In recorded telephone calls from
prison made after his arrest, the appellant confirmed to family members that he
had been into the newsagency but denied that he was present at the time of the
attack on Mrs Poll.
Evidence of Ms Deborah Parsons – male of a similar description
24 According to Ms Richardson, at the time the appellant lived with her at
Lawrie Avenue, and visited her there in 1993, he had dark hair and ‘prominent’
dark eyebrows.

[2023] SASCA 80 The Court

25 Sometime between about 9:10pm and 9:15pm on the evening of the murder,
a witness, Ms Parsons, saw a young man with dark hair and thick, dark eyebrows,
with his hands inside the pockets of a long coat, walking purposefully through a
car park located between the newsagency and the Salisbury railway line. The male
was heading from the general direction of the crime scene to the direction of the
home of the appellant’s mother. Ms Parsons said that as her vehicle approached
the young man, he spun around to face her, adopting an aggressive and defensive
semi-crouched stance; and it appeared he had been sweating.
26 The prosecution relied on the evidence of Ms Parsons as a piece of
circumstantial evidence as to identity; that is, a young man fitting the general
physical appearance of the appellant was seen in the area of the shop heading
towards the home of the appellant’s mother shortly after the commission of the
offence.
Shoe impressions
27 Following his arrest in September 2019, the appellant’s known shoe size was
a men’s size nine, which was within the same size range as the shoe impressions
of unknown origin located at the crime scene.
Appellant’s conversations with M
28 In July 2019, prior to the appellant’s arrest, and at a time when he could not
have known he was a person of interest in connection with Mrs Poll’s murder, the
appellant had a conversation with his then intimate partner, M, in Warrnambool
(‘the Warrnambool conversation’). It was M’s evidence that the appellant told her
that when he was younger he had an affair with an older married woman who
worked in a shop that he used to go into and that this woman had been knifed to
death by her husband.
29 On the prosecution case, it was open to the jury to conclude that the appellant
was talking about Mrs Poll and thereby asserting a ‘connection’ to her. On the
defence case, the appellant was discussing a different woman in different terms.
This conversation is the subject of Appeal Grounds 3 and 3A.
30 With that overview of the evidence and the issues in dispute at trial, we turn
to consider the appeal grounds.
Ground 1 – Directions as to motive
31 The appellant complains that the trial Judge erred as a matter of law in his
directions to the jury regarding the absence of motive. The evidence at trial
revealed no motive for the appellant to commit the offence. While there was some
evidence suggestive of a robbery, it was not relied upon by the prosecution in proof
of the appellant’s guilt.
32 Both the prosecutor and defence counsel addressed the jury as to the absence
of motive. The prosecutor emphasised that while there was no evidence of a
-- 13 of 90 --
[2023] SASCA 80 The Court
10
motive for the appellant to attack Mrs Poll, that did not detract from the
incriminatory evidence against him. The prosecutor submitted that even without
an apparent motive, there was no reasonable view of the blood and DNA
deposition evidence consistent with innocence. The prosecutor urged the jury to
delineate between a lack of motive and a lack of involvement in the crime and said:
The weight of the evidence reveals Suzanne Poll was happily married, supported by her
family, and committed to her job. The point is not to say she could not possibly have had
any enemies but rather to highlight the absence of anyone having an obvious motive to
harm her. That is just another way of making the point that the absence of motive is not
the be-all and end-all of determining a charge of murder because sometimes there is just
no explicable reason for why things happen as they do.
33 Defence counsel also addressed the jury on the absence of motive and said
that while motive was not an element of the offence, the jury ‘might still think that
in a case like this [motive] is important’. Defence counsel said:
Now, robbery has been mentioned. Would you kill like that and not get the money? These
are really ruminations or questions, rhetorical questions I’m posing. I don’t pretend, on the
evidence, to be able to assist you about the motive here.
34 …
So, what to make of motive. You might think you’re not assisted very much by the
evidence in this case about what the motive was. It has been described as a ferocious attack,
and you might agree.
One thing which hasn’t been addressed is that we know from Dr James that Mrs Poll met
her death lying face down because she received those stab wounds in the back and the exit
wounds came out the front. But Darryl Poll describes arriving and he doesn’t describe
turning her over, for example. So, has someone committed this ferocious attack and then
turned her over? Is that the act of someone who knows her well? What does that tell you
if anything?
35 It can be seen that both parties addressed the jury on the topic of motive, and
the absence of the appellant having had a motive to murder Mrs Poll. On the one
hand, the prosecutor contended that the absence of motive did little to undermine
the strength of the prosecution case; while on the other, defence counsel
emphasised that the appellant had no motive to have committed an offence
characterised by its brutality suggestive of animosity between the offender and
Mrs Poll.
36 The trial Judge instructed the jury that it was not for the prosecution to prove
that the appellant had a motive to commit the offence; but the presence or absence
of motive was a relevant matter for the jury to consider when assessing whether
guilt had been established. The trial Judge instructed the jury not to speculate as to
possible motives on the part of the appellant and cautioned the jury against
‘bootstrap reasoning.’ His Honour also noted that there is a distinction between the
absence of proven or apparent motive, on the one hand, and proven absence of
-- 14 of 90 --
[2023] SASCA 80 The Court
11
motive, on the other. His Honour instructed the jury that this was a case involving
the former:
It is not for the prosecution to say why a person did kill a deceased person if it can be
satisfactorily proved beyond reasonable doubt that he did do that killing and that you are
prepared to infer from the circumstances I have taken you to before that it was not an
accident and that it had the intention of killing or causing at least grievous bodily harm.
We have been through that.
Of course, as I said at the outset, it is only human and reasonable to ask oneself ‘The
accused is charged with murder, why would he do that? What is his motive?’, so you may
look at the presence or absence of motive as a relevant matter when deciding whether the
prosecution have indeed proven that the accused did commit the crime of murder but, as I
have told you already, the prosecution do not have to prove, do not have to explain what
the motive was because they would not know what it was themselves in a case like we have
got here.
The next thing is that in a case such as this where the evidence does not clearly establish a
definite motive for the accused to kill the deceased one must not adopt a process of, or akin
to, speculating upon what motive he may have had and then using such possibility as a
factor to be taken into account in assessing whether guilt has been established.
You can understand that is bootstraps reasoning, you know what that is: you cannot lift
yourself up by your own bootstraps. It is sort of assuming that the person is guilty and
asking why did he do it and then taking that speculation as to why he did it back to the
original question of whether or not he did it. I will leave that with you, that is perhaps not
the easiest thing I have discussed today, but it is not unimportant.
As I say, you can look at the situation of motive, you can take it into account with all of the
rest of the facts before you when coming to that final decision as to whether or not it has
been proven beyond reasonable doubt that the accused did commit murder.
I will put it in another way, which may or may not help you. It is another way of expressing
what I have already put, so do not be worried about it because I am not suddenly putting
something different or new. But in a number of cases, and in a decision of the High Court
in De Gruchy v The Queen, the judges have explained that although an absence of evidence
of possible motive is clearly a matter to be taken into account by the jury (as I have said to
you that it is, particularly in a case based on circumstantial evidence, as this case is) there
is a critical distinction between two things: between the absence of proven or apparent
motive on the one hand and proven absence of motive on the other.
In other words, these are my words now, you have got to remember that you can have an
absence of evidence of motive in a particular case, in other words prosecution tender their
evidence, what they have got and there is an absence of evidence of motive there, so there
is that. But that does not equate to proof that the accused could not have had some unknown
motive or reason to commit the charged crime.
In other words, a person may have a reason that seems good to him, however logical or
illogical, but which is never revealed and he commits a crime. Prosecution cannot stand
up and say ‘Here is our evidence, here is all the circumstantial evidence that he committed
a crime and here is our evidence as to why he did it’, but the fact that they do not lead
evidence as to why he did it, or cannot do so, does not amount to proof that there was no
motive because you simply do not know in a circumstance like that. You have to keep
those situations apart.

(emphasis added)
37 Later, in summarising the prosecution case, his Honour said:
Next, the prosecutor referred to the fact that the deceased had no known enemies and,
clearly, Mr Poll was not the killer. You can entirely discount him as the police have. There
can be no suggestion that he was. So, the prosecutor says ‘Well, the motive is unclear, we
do not know.’ Well, that is a responsible position to take and I have already directed you
about the matter of motive and the prosecution do not have to prove a motive in
circumstances where they simply cannot say, so I leave that with you.
(emphasis added)
38 The appellant contends that the trial Judge erred in his directions on motive.
First, the appellant submits that the trial Judge, in referring to the prosecution’s
stance in relation to motive as ‘a responsible position to take’, diluted the
importance of the absence of motive to the defence case. Second, the appellant
contends that the trial Judge erred by directing the jury that the prosecution do not
have to prove a motive because ‘they would not know what it was themselves in a
case like we have got here.’ The appellant complains that the inadequacy of the
directions as to the absence of motive has resulted in a miscarriage of justice.
39 In De Gruchy v The Queen,1 Gaudron, McHugh and Hayne JJ drew a
distinction between an absence of apparent motive, on the one hand, and proven
absence of motive, on the other:2
The absence of evidence of possible motive is clearly a matter to be taken into account by
a jury, particularly in a case based on circumstantial evidence. However, if, as in the
present case, the prosecution does not have to establish motive, it is difficult to say that the
absence of evidence in that regard is a matter of “positive significance”, either in the sense
that it is a weakness in the prosecution case or a strength in the defence case. It might be
otherwise if there were positive evidence that the accused lacked motive. However, that
would be a most unusual case. The present is not a case of that kind. It is simply a case
where there was no evidence of motive.
40 Relevantly, in a separate judgment, Kirby J set out some general propositions
relevant to directions on motive and, in particular, the absence of motive. His
Honour said:3
(1) No general direction can be formulated to accommodate all the different circumstances
that can arise. If any directions are given on the subject of motive, they should be brief
because the consideration of the relevance of motive (or lack of it) is quintessentially
a task for the jury, viewing questions about motive in the context of the evidence as a
whole.
(2) Where the prosecution has not sought, or has failed, to prove a motive on the part of
the accused for the crime, the judge may consider whether it is appropriate to make it
clear to the jury that the prosecution has no obligation to show a possible motive, and

-- 16 of 90 --
[2023] SASCA 80 The Court
13
that the absence of a proved motive cannot as a matter of law be fatal to its case.
Sometimes the precise motives of individuals (if any) will never be known to anyone
other than themselves. In such circumstances, it would be completely unreasonable to
require the prosecution to prove a motive and the law does not impose that obligation.
…
(5) Where there is no evidence that the accused had a motive to commit the crime alleged,
that is “always a fact in favour of the accused”. There is some authority to suggest that
a trial judge need not draw that fact to the notice of the jury. However, especially in
circumstances of a heinous crime, if a judge gives any direction about motive, it would
generally be fair and prudent to draw to the jury's notice the absence of proved motive
as a consideration favouring the accused. As Griffith CJ observed: “the more heinous
the act … the more important becomes the question of motive.” If none is proved, that
is a consideration that the jury will need to weigh in judging whether the prosecution
has proved the guilt of the accused to the criminal standard.
(6) Nonetheless, if any such comment is made, it should be balanced by drawing attention
to the obvious fact that, in a particular case, “there may be a motive, and perhaps a
strong one, but no evidence of it available”. In Pointer v United States, the Supreme
Court of the United States put it this way: “The absence of evidence suggesting a
motive for the commission of the crime charged is a circumstance in favor of the
accused, to be given such weight as the jury deems proper; but proof of motive is never
indispensable to conviction.”
(citations omitted)
41 We are satisfied that the trial Judge’s directions were not inadequate as to
motive. As set out above, the trial Judge directed the jury that the term ‘motive’ is
used in the sense of having a reason to do a particular act and noted that there may
be many reasons for doing an act; and proof of motive is not an element of the
offence of murder and need not be proved by the prosecution. His Honour
instructed the jury that in a case such as this, where the evidence does not clearly
establish a motive for the accused to kill Mrs Poll, one must not adopt a process
of, or akin to, speculating about what motive he may have had and then use that
possibility as a factor to be taken into account in assessing whether guilt has been
established, or engage in ‘bootstrap reasoning’. As his Honour made clear, the
absence of motive is still to be taken ‘into account with all the rest of the facts’ by
the jury when coming to the final decision of whether or not it has been proven
beyond reasonable doubt that the accused was guilty of murder.
42 In light of those directions, there is no basis to suggest that the jury would
have failed to understand that while the prosecution need not prove motive beyond
reasonable doubt, an absence of motive on the part of the appellant was a factor
which they could take into account when determining whether his guilt had been
proved. Whilst the trial Judge noted that the prosecution’s position as to motive
was ‘responsible’ and the prosecution ‘would not know what [the motive] was
themselves in a case like this’, those statements were directed towards, and would
have been understood as, referable to the prosecution’s approach in not relying on
a motive when there was no evidentiary basis for doing so.
-- 17 of 90 --
[2023] SASCA 80 The Court
14
43 Whilst it would have been preferable for the trial Judge to have referred to,
or summarised, defence counsel’s arguments as to the appellant’s lack of motive
to commit the offence, we are satisfied that the failure to do so did not result in a
miscarriage of justice. The jury would have well understood that the apparent
absence of a motive for the appellant to commit the offence was a factor which
they could take into account when determining whether the prosecution had proven
the appellant’s guilt beyond reasonable doubt.
44 Further, defence counsel did not, at any point during the summing up, request
that the trial Judge give further directions on the topic of motive. While not
determinative, the absence of any such request provides some practical indication
that the trial Judge’s directions were sufficient to resolve the issues in the case.
45 We refuse permission to appeal on Ground 1.
Grounds 2 and 2A – The blood and DNA deposition evidence
46 These grounds of appeal relate to the alleged wrongful admission of the DNA
evidence, and the trial Judge’s directions as to the blood and DNA deposition
evidence.
Ground 2A – Admissibility of the DNA results
47 The appellant complains that the trial Judge erred as a matter of law in
admitting evidence of the DNA results. There are four limbs to this argument
which are as follows. First, the trial Judge provided inadequate reasons for his
ruling which did not sufficiently expose the process of reasoning by which he
admitted the DNA evidence. Second, the use of ‘familial testing’ constituted a
breach of the CLFPA such that the evidence ought to have been excluded in the
exercise of the discretion reposed in Bunning v Cross (‘the discretion’).4 Third,
police obtained the appellant’s DNA sample through unlawful or improper
behaviour and the evidence ought to have been excluded in the exercise of the
Court’s discretion. Fourth, the DNA evidence was inadmissible by reason of the
prosecution’s inability to prove the chain of evidence or exclude the risk of
contamination beyond reasonable doubt. In effect, the fourth limb of the complaint
invokes largely the same submissions made in relation to Ground 2.
48 At trial, defence counsel challenged the DNA results on the basis that
‘familial searching’ by Forensic Science South Australia (‘FSSA’) of the South
Australian Criminal Reference and Evidence DNA Database (‘SACREDD’)
which provided information that the appellant’s brother was a possible relative of
the unknown male contributor to the crime scene sample JPH6.1.A, was unlawful.
Evidence regarding the process of ‘familial searching’ undertaken at FSSA was
adduced from two forensic scientists who were employed there at the relevant
time: Dr Duncan Taylor and Dr Damien Abarno.
4 Bunning v Cross (1978) 141 CLR 54.
-- 18 of 90 --
[2023] SASCA 80 The Court
15
49 The trial Judge ruled that the DNA evidence was admissible as a matter of
law and, in any event, he would not have exercised his discretion to exclude the
evidence. His Honour said:
I presently have before me a rule 49 notice filed by the defence which seeks 10 orders
concerning exclusion of evidence.
…
As to proposed order 5 concerning the DNA evidence, I now rule in favour of the
prosecution and rule that the DNA evidence is, in fact, admissible as a matter of law.
Of course, I have to also consider the further question of discretionary exclusion. I note, of
course, s.47 of the Forensic Procedure Act does refer to this topic, but 47(1) is limited to
evidence which is obtained as a result of the forensic procedure. And that evidence is stated
to be not admissible in evidence against the person on whom the procedure was carried out.
That, of course, is not the factual situation in the present case, and counsel for the defence
quite reasonably concedes that that is the position, and that what she is, in fact, relying upon
is the common law Bunning v Cross discretion to exclude.
As to the exercise of that discretion, I would decline to exclude any of the evidence, having
taken into account all of the well-known factors referred to in Bunning v Cross and, of
course, the facts and circumstances in this particular case.
I do not propose to give any further detailed reasons on that now but that is my ruling.
Adequacy of reasons
50 As to the first limb, the appellant submits that the trial Judge’s reasons are
inadequate.
51 The obligation to give reasons for intermediate evidentiary rulings was
considered by the Full Court of the Supreme Court of Western Australia in
Webb v The Queen5 (‘Webb’). Justice Ipp said:6
Where an omission to give reasons at the conclusion of a voir dire concerning the
admissibility of a confession results in it not being possible to determine whether the
presiding judge has considered the true issues, and whether he has applied the appropriate
legal principles and has taken all relevant factors into account, legal error is disclosed. If
that were not the case the statutory right of appeal would be rendered nugatory. It is crucial
that the judge's reasons be sufficient to satisfy the overriding principle, namely, that the
decision be couched in such a form as to make it possible for an appellate court, fairly, to
assess its merits.
52 The case of Webb involved the admissibility of a confession where in issue
was the appellant’s intellectual capacity to comprehend relevant matters whilst
giving evidence. The Court held that the reasons were inadequate as they did not
5 (1994) 13 WAR 257.
6 Webb v The Queen (1994) 13 WAR 257 at 271 per Ipp J (with whom Malcolm CJ and Seaman J agreed).
-- 19 of 90 --
[2023] SASCA 80 The Court
16
reveal whether the judge, at first instance, had properly considered the relevant
issues and applied the appropriate legal principles. As the matter concerned a
factual dispute turning on issues of credibility, the Court was not in the same
position as the primary judge to arrive at its own view; and the appeal was allowed.
53 In Madubuko v The Queen7 the Court of Criminal Appeal of New South
Wales considered the failure to give reasons in the context of an application by the
appellant for a separate trial. The appellant complained that the failure to provide
reasons constituted an error of law. In dismissing the appeal, Hodgson JA said:8
Considering first the question of failure to give reasons, such failure does generally
constitute an error of law where reasons are appropriate, but this does not necessarily
require that an appeal be upheld. In particular, if the matter as to which reasons are not
given is one on which an appeal court can come to its own view, and if that view is that the
result arrived at by the primary judge was correct, then normally an appeal would be
dismissed.
54 In the present case, the trial Judge was required to determine whether familial
searching was permitted under the CLFPA. This involved an exercise in statutory
construction. Depending on the determination of that question, the trial Judge was
then required to determine whether the DNA results (subsequently obtained from
a comparison between the appellant’s DNA profile taken from his arrest buccal
swab and the crime scene samples) ought to be excluded in the exercise of his
discretion. In considering whether to exercise his discretion to exclude the
evidence, the trial Judge was also required to take into account defence counsel’s
submission as to the lawfulness by which the appellant’s DNA sample was first
obtained by police from a coffee cup which was said to have been discarded by the
appellant into a nearby bin.
55 It is to be accepted that the trial Judge’s reasons were brief and did not
specifically address the issues raised by counsel, nor provide an analysis of the
relevant legislative provisions which were the subject of comprehensive oral and
written submissions. However, the absence of detailed reasons does not present
this Court with any impediment in determining whether the trial Judge’s ruling
was correct. In doing so, there is no need for this Court to consider any issues of
credibility, nor is there any dispute as to the factual basis upon which the issues
arise for determination. The trial Judge did not enjoy any advantage over this
Court in deciding whether the DNA evidence ought to be admitted. Accordingly,
if the DNA evidence was properly admitted, the brevity of reasons for doing so
does not constitute an error of law which would require that the appeal be allowed.
Familial Searching
56 Turning to the appellant’s second contention, that the trial Judge erred in
finding that ‘familial searching’ was authorised by the CLFPA or, alternatively,
7 (2011) 210 A Crim R 249.
8 Madubuko v The Queen (2011) 210 A Crim R 249 at [22] per Hodgson JA (with whom Hoeben J and
Grove AJ agreed).
-- 20 of 90 --
[2023] SASCA 80 The Court
17
that he erred in declining to exclude the DNA evidence in the exercise of his
discretion, we first set out the statutory framework upon which the appeal must be
decided.
The statutory framework
57 The CLFPA provides for the carrying out of forensic procedures to obtain
evidence relevant to the investigation of criminal offences and for other purposes,
and to make provision for a DNA database. The CLFPA confers power, in certain
stated circumstances, upon the police or a law enforcement authority to obtain
forensic material (relevantly, a DNA sample and DNA profile) from a person
through the conduct of a forensic procedure.
58 The CLFPA purports to strictly regulate the circumstances in which a DNA
profile may be obtained in the course of carrying out a forensic procedure; what
may, or may not, be done with a DNA profile once obtained; and what may, or
may not, be done in relation to the DNA database.
59 The structure of the Act is as follows:
1. Part 1 includes an interpretation section.
2. Part 2 authorises the carrying out of forensic procedures upon persons.
There are four categories of ‘persons’ defined under this Part. Division
1 governs procedures relating to volunteers and victims. Division 2
governs procedures relating to suspects. Division 3 governs procedures
relating to offenders. Division 4 governs blood testing of certain
persons for communicable diseases.
3. Part 3 makes provision for the carrying out of forensic procedures.
4. Part 4 concerns material obtained by the carrying out of forensic
procedures and how it is to be dealt with.
5. Part 5 makes provision for the ‘DNA database system’, including access
to, and use of, the database.
6. Part 6 concerns evidence including the effect of non-compliance with
the CLFPA.9
7. Part 7 concerns miscellaneous matters including confidentiality or
non-disclosure provisions.10
60 The terms ‘forensic material’ and ‘forensic procedure’ are defined in s 3 as
follows:
9 Relevantly, s 47 of the CLFPA relates to the effect of non-compliance on the admissibility of
evidence.
10 Relevantly, s 50 of the CLFPA sets out the requirements in relation to confidentiality.
-- 21 of 90 --
[2023] SASCA 80 The Court
18
forensic material means material obtained by carrying out a forensic procedure (but
does not include the results of the analysis of any such material);
forensic procedure means a procedure carried out by or on behalf of South Australia
Police or a law enforcement authority and consisting of—
(a) the taking of prints of the hands, fingers, feet or toes; or
(b) an examination of a part of a person's body (but not an examination that can
be conducted without disturbing the person's clothing and without physical
contact with the person); or
(c) the taking of a sample of biological or other material from a person's body (but
not the taking of a detached hair from the person's clothing); or
Note—
This would include, for example, taking a sample of the person's hair, a
sample of the person's fingernails or toenails or material under the
person's fingernails or toenails, a blood sample, a sample by buccal
swab or a sample of saliva.
(d) the taking of an impression or cast of a part of a person's body;
Note—
This would include, for example, the taking of a dental impression or
the taking of an impression or cast of a wound.
61 In relation to the retention of DNA samples and DNA profiles, s 41(1)
provides that the Commissioner of Police may maintain a ‘DNA database system’.
62 The term ‘DNA database system’ is defined in s 40 of the CLFPA as follows:
DNA database system means a database (whether in computerised or other form and
however described) containing—
(a) the following indexes of DNA profiles and information that may be used to
identify the person from whose biological material each DNA profile was
derived:
(i) a crime scene index;
(ii) a missing persons index;
(iii) an unknown deceased persons index;
(iv) a suspects/offenders index;
(v) a volunteers (unlimited purposes) index;
(vi) a volunteers (limited purposes) index; and
(b) a statistical index; and
-- 22 of 90 --
[2023] SASCA 80 The Court
19
(c) any other index prescribed by the regulations;
63 Relevantly, the terms ‘crime scene index’ and ‘suspects/offenders index’ are
also defined in s 40 as follows:
crime scene index means an index of DNA profiles derived from biological material
found—
(a) at any place (whether within or outside Australia) where an offence was, or is
reasonably suspected of having been, committed; or
(b) on or within the body of the victim, or a person reasonably suspected of being
a victim, of an offence; or
(c) on anything worn or carried by the victim at the time when an offence was, or
is reasonably suspected of having been, committed; or
(d) on or within the body of any person, on any thing, or at any place, associated
with the commission of an offence;
…
Suspects/offenders index means an index of DNA profiles derived from forensic material
of persons—
(a) on whom forensic procedures have been carried out in accordance with an
authorisation under Part 2 Division 1 if an assimilation order has been made
in relation to the material or a court or other authority has ordered, in
accordance with a corresponding law, that the material be treated as if it were
material obtained from a person suspected of an offence; and
(b) on whom forensic procedures have been carried out in accordance with an
authorisation under Part 2 Division 2, or a corresponding law; and
(c) on whom forensic procedures have been carried out in accordance with an
authorisation under Part 2 Division 3 or a corresponding law.
64 The DNA database maintained by the Commissioner is, as previously
mentioned, called ‘SACREDD’.
65 Other provisions in Part 5 of the CLFPA regulate what information from
forensic material may be included in the database, and creates offences for the
unauthorised storage, accessing and retention of such information, as well as a
criminal penalty provision for intentional or reckless disclosure of such
information.
66 Section 45(2) sets out the purposes for which a person authorised by the
Commissioner of Police may access information stored on the DNA database. It
provides:
(2) A person authorised by the Commissioner of Police may access information stored
on the DNA database system for 1 or more of the following purposes:
-- 23 of 90 --
[2023] SASCA 80 The Court
20
(a) for the purpose of comparing a DNA profile stored on an index of the DNA
database system with any other DNA profiles stored on the DNA database

The forensic processes undertaken by FSSA
68 In considering whether ‘familial searching’ is permitted under the CLFPA, it
is necessary to outline the specific forensic processes by which the relevant DNA
profiles were obtained, and the scientific tasks undertaken in this case, which have
compendiously been referred to as ‘familial searching.’
69 The appellant’s DNA profile was obtained in the following way.
70 An investigation into the murder of Mrs Poll commenced in April 1993. No
arrest was made, and the investigation remained open. In 1993, various crime
scene samples (collected from the newsagency store) were analysed at FSSA
utilising DNA profiling systems, available at the time, which targeted up to four
regions, or loci, on the DNA strand. In 1999, FSSA commenced using the Profiler
Plus System which targeted nine loci, plus a gender determining locus, and carried
-- 25 of 90 --
[2023] SASCA 80 The Court
22
greater discriminating power in distinguishing individuals. In December 2001,
FSSA reported that one of the crime scene samples (from a plastic holder
containing receipts and paperwork in Mrs Poll’s handbag labelled JPH1.6.A)
yielded a DNA profile of an unknown male on an item described as ‘a plastic
holder and receipts and motor reg papers from black handbag’. This unknown male
DNA profile was uploaded onto the SACREDD.
71 As of August 2009, there was no match between the unknown male DNA
profile and any other DNA profile held on the SACREDD. Police requested FSSA
to compare the unknown male DNA profile against other DNA profiles held in the
database to identify possible relatives of the donor of that sample. It is this process
of comparison which is described as ‘familial searching’. We will set out in more
detail later the scientific task involved in that process in this case.
72 Dr Taylor, a Forensic Scientist at FSSA, undertook the process of familial
searching and identified a number of potential female relatives of the donor of the
unknown male DNA profile (‘the first familial search’).
73 As of 29 November 2016, there was still no match between the unknown
male DNA profile and any other DNA profile held on the database. Dr Taylor
undertook a second familial search. By this time the FSSA was using the
GlobalFiler DNA Profiling System targeting 21 loci on non-sex chromosomes and
three loci on sex chromosomes. Thus, it had greater power to distinguish relatives
from non-relatives. In addition to identifying several potential female relatives of
the donor of the unknown male profile, this second familial search identified one
potential male relative on the basis of shared possession of the same
Y-Chromosome profile. The male relative was identified as the appellant’s brother,
whose DNA profile was on the suspects/offenders index of the SACREDD.
74 There was no suggestion at trial, or before this Court, that the DNA profile
of the appellant’s brother, or the DNA profile of the unknown male, were not
lawfully and properly on the relevant indices of the database.
75 The second familial searching report was forwarded by the FSSA to the
investigating police officer, Detective Roderick Huppatz. He then made inquiries
into members of the Tilley family and, ultimately, the appellant.
76 On 5 September 2019, Detectives Huppatz and Tucker travelled to Ballarat,
Victoria and, once there, contacted the appellant advising him of their wish to
speak with him.
77 On 6 September 2019, they met with the appellant in Daylesford and advised
him that a family member (his brother) whose profile was on the DNA database
was similar to a DNA profile located at the crime scene of the murder of Mrs Poll.
Detective Huppatz also advised the appellant of the possibility of a male relative
of the appellant’s brother having a similar or matching DNA profile, and requested
a ‘volunteer sample’ from the appellant. The appellant declined to provide a
-- 26 of 90 --
[2023] SASCA 80 The Court
23
sample. A short time later, Detective Huppatz observed the appellant discard a
disposable coffee cup into a public rubbish bin. Once the appellant had left the
area, Detective Huppatz retrieved the coffee cup from the bin, sealed it in a paper
envelope and brought it back to Adelaide where it was subsequently submitted to
FSSA for DNA analysis.
78 Dr Taylor extracted a mixed DNA profile from a sample taken from the
coffee cup, the major component of which was compared to the unknown male
DNA profile from the crime scene sample JPH1.6.A. Dr Taylor calculated a
likelihood ratio of more than 100 billion in favour of the hypothesis that the
contributor of the major component of the DNA sample taken from the coffee cup
was a contributor to the single source crime scene profile extracted from sample
JPH1.6.A.
79 On 21 September 2019, on the basis of that aforementioned DNA result, the
appellant was arrested for the murder of Mrs Poll. On 23 September 2019, he was
extradited to South Australia and police took a buccal swab from him. There was
no dispute that the appellant’s arrest buccal swab was lawfully obtained under the
CLFPA. The forensic material from the appellant’s buccal swap was used for
comparison with the crime scene samples (including JPH1.6.A) resulting in the
impugned DNA evidence.
80 Thus, there were in fact three processes engaged in by the FSSA which
produced the DNA results.
81 The first process involved the ‘familial searching’ of the database. More
specifically, Dr Taylor compared the DNA profile of the unknown contributor to
sample JPH1.6.A with profiles on the suspects/offenders index on SACREDD
(including that of the appellant’s brother). This involved identifying the
commonality of alleles between two profiles (one being the unknown male DNA
profile extracted from JPH1.6.A) with a view to drawing some statistical
evaluation as to the relatedness between the donor of the two DNA profiles. FSSA
then conducted an analysis of Y-Chromosome short tandem repeats (Y-STR)
profiles, which enabled the identification of potential close male relatives on
account of the Y-Chromosome passing down unchanged via paternal lineage.
82 More specifically, in the second familial search, Dr Taylor compared the
unknown male profile to reference profiles of suspects and convicted offenders
that had been uploaded to SACREDD up to 25 October 2016.11 Dr Taylor
calculated paternity12 and sibship13 indexes and then further investigated the top
100 most likely potential relatives. Following analysis on the GlobalFiler system,
it was determined that the appellant’s brother possessed the same Y-Chromosome
11 The first search only identified potential female relatives.
12 A paternity index is a ratio that specifically considers the likelihood of two people being a parent and
child, as opposed to being unrelated.
13 A sibship index is a ratio that specifically considers the likelihood of two people being either siblings
or unrelated.
-- 27 of 90 --
[2023] SASCA 80 The Court
24
profile as the unknown male contributor to the DNA profile extracted from
JPH1.6.A. Further, the sibship index was 255, meaning that the probability of
obtaining the profile of the unknown male DNA sample and the profile of the
appellant’s brother was 255 times higher if they were siblings than if they were
unrelated to each other. This likelihood ratio was described as ‘very strong
support’ for that hypothesis.
83 The second forensic process undertaken by the FSSA involved extracting a
DNA profile from a swab taken from the discarded coffee cup. It was common
ground at trial, and in this Court, that this process did not involve a ‘forensic
procedure’ as defined by the CLFPA. Further, the DNA profile was not uploaded
to the database because it did not meet the definition of ‘forensic material’ that
may form part of the crime scene index (or any other index). The FSSA compared
the DNA profile obtained from the discarded coffee cup with the unknown male
DNA sample taken from the crime scene sample JPH1.6.A. This was a direct
comparison between DNA profiles which did not involve accessing the DNA
database.
84 The third process engaged in by the FSSA occurred after the appellant’s
arrest. The appellant’s DNA profile was obtained from the buccal swab taken upon
his arrest. The FSSA then conducted a series of direct comparisons between the
appellant’s DNA profile and various crime scene samples. The results of that
forensic work gave rise to the impugned DNA results/evidence adduced at trial.
The parties’ submissions
85 The appellant contends that the process of ‘familial searching’ is not
permitted under the CLFPA. The CLFPA allows for the obtaining of DNA profiles,
and the retention of those DNA profiles onto a DNA database, in strictly prescribed
circumstances. It amounts to legislation which authorises intrusion into an
individual’s privacy and what would otherwise be tortious conduct. Accordingly,
the legislative provisions should be strictly construed and applied.
86 The appellant emphasises that throughout the CLFPA a distinction is drawn
between the rights of offenders as opposed to other members of the community.
For example, there are three lawful means by which a person’s DNA profile may
be obtained under the Act: volunteers and victims’ procedures, suspects
procedures, and offenders’ procedures. In the case of a person who is not a suspect
or an offender, there is no power to compel the provision of forensic material. The
incursions permitted in respect of offenders are not permitted on other members of
the community.
87 Moreover, the CLFPA creates a DNA database in two parts: one containing
profiles and information that may be used to identify the person from whose
biological material each DNA profile was derived (an ‘identified database’); and
one which is compiled for statistical purposes and cannot be used to discover the
identity of persons from whom the biological material was obtained (a ‘statistical
-- 28 of 90 --
[2023] SASCA 80 The Court
25
database’). Thus, it is submitted that the CLFPA strictly regulates the use to which
the profiles may be put.
88 The appellant submits that familial searching effectively creates ‘virtual
profiles’ on the DNA database for relatives of persons legitimately on the database
and, in that way, undermines the distinction the CLFPA seeks to draw between
different categories of persons. Whilst the Act recognises that offenders and
suspects have diminished rights of genetic privacy, that rationale does not apply to
relatives of suspects or offenders. The appellant submits that if familial searching
is permitted under the CLFPA, relatives of persons who are suspects or offenders,
in effect, have less protections than those afforded to persons who volunteer
forensic material and from whom consent is required before their DNA is put on
the identity database.
89 The appellant submits that in the absence of express reference to familial
searching by Parliament, it is not permitted under the CLFPA. Where there are
clear restrictions on whose DNA may be obtained, what forensic material can be
included on the DNA database and for what purpose, the CLFPA should not be
construed as allowing ‘the effective inclusion in the database of persons who do
not meet these restrictions.’ In the absence of express language to the contrary, the
appellant submits that this Court should assume that Parliament did not intend the
legislation to impinge on fundamental rights, namely the right to genetic privacy.
90 For the respondent, it is contended that familial searching does not involve
an unlawful use of the DNA database. The respondent submits that s 45(2)(a) of
the CLFPA expressly allows a ‘familial search’ in the sense that the technical
forensic searching task undertaken in this case involved a comparison of DNA
profiles lawfully stored on the database.
Consideration
91 This Court must begin with the words used by the section considered in their
statutory context. A plain reading of s 45(2)(a) permits an authorised person to
access information stored on the database for the purpose of comparing one profile
stored on the database with another profile stored on the database. In the present
case, the scientific task described as ‘familial searching’ involved the comparison
of DNA profiles lawfully stored on the database. More specifically, the FSSA
undertook numerous individual comparisons of DNA profiles in the
suspects/offenders index and identified one potential male relative of the donor of
the unknown male DNA profile taken from the crime scene sample JPH1.6.A.
92 Contrary to the appellant’s contentions, a plain reading of s 45(2)(a) which
permits familial searching is also supported by the broader context, and purpose,
of the CLFPA.
93 The legislative provisions, which provide for a DNA database and regulate
the information which may be stored within the database and its use, are enacted
in the context of a statutory scheme which envisages the storage of DNA profiles
-- 29 of 90 --
[2023] SASCA 80 The Court
26
on a database for future use in connection with ongoing and future criminal
investigations, and for admission into evidence.
94 Notwithstanding the express strictures within the CLFPA as to what will
constitute an impermissible use of the database, it does not expressly preclude
familial searching (in terms of the scientific processes which were undertaken in
this case.) By contrast, for example, s 45(3)(a) provides that a person must not
compare a DNA profile stored on the volunteers (limited purposes) index, with a
DNA profile stored on another index, if the volunteer has not granted consent.
There is no such restriction placed on the use of familial searching.
95 Further, s 50 of the CLFPA prohibits disclosure of information stored on the
database unless the disclosure is necessary for a specified purpose or otherwise
authorised by the section. The disclosure exceptions in s 50(1) align with the
permissible use provisions in s 45(2). In particular, s 50(1)(a) permits disclosure
where it is ‘necessary for criminal investigation purposes or a missing persons
enquiry’, and complements s 45(2)(a) which authorises the disclosure of results of
a database search to law enforcement for the purpose of criminal investigation.
Thus, read together, ss 45 and 50 govern the permissible and impermissible uses
of forensic material stored within the DNA database and support a plain reading
of s 45(2)(a) to permit familial searching as it was conducted in this case.
96 In relation to the appellant’s submissions that familial searching (as it was
conducted in this case) infringes a person’s right to genetic privacy such that,
unless expressly provided, s 45(2)(a) should not be construed to permit familial
searching, it is important to emphasise the limited reach of the actual processes
undertaken. The familial searching conducted in this case did not reveal the
appellant’s DNA profile, nor did it migrate his DNA profile into the database at
all. The familial searching exercise only resulted in the identification of the
appellant’s brother as a potential male relative of the contributor to the unknown
male DNA profile extracted from the crime scene sample JPH1.6.A. It did not
engage directly, or at all, with the appellant’s DNA profile. As much is borne out
by the prosecutor’s concession at trial that the police, upon receipt of the second
familial search report, did not have reasonable cause to suspect the appellant of
having committed the offence; and once he declined to provide his DNA sample,
they had to resort to other investigative techniques outside of conducting a forensic
procedure (as defined in the CLFPA) to further their investigation.
97 It is a moot point whether, if the appellant had been included in the volunteers
(limited purposes) index, familial testing may still have revealed that he was a
relative of the appellant’s brother (without his consent) as, without more, that
information would not reveal or yield any information about his DNA profile and
would not infringe any right he may have had to genetic privacy.
98 For those reasons, we are satisfied that s 45(2)(a) of the CLFPA permits the
scientific task of familial searching, as it was conducted in this case, and it was not
unlawful.

The appellant’s DNA from the discarded coffee cup
99 The appellant contends the mechanism by which police obtained his DNA
profile was unlawful or improper such that it ought to have been excluded in the
exercise of the Bunning v Cross discretion. In support of that contention, the
appellant submits that the CLFPA codifies the powers of police to obtain forensic
samples; and his DNA sample was obtained outside of the procedures permitted
by it. The appellant submits that having exercised his right to refuse to undergo a
forensic procedure, the police’s conduct in seizing his discarded coffee cup
undermined that right and directly contravened the CLFPA.
100 The CLFPA regulates the circumstances in which a DNA profile may be
obtained by the carrying out of a forensic procedure. The conduct of Detective
Huppatz in seizing the appellant’s discarded coffee cup did not constitute a
‘forensic procedure’ as defined in the CLFPA. Further, the sample extracted from
the coffee cup (from which a DNA profile was obtained) did not constitute
‘forensic material’ in that it was not ‘material obtained by carrying out a forensic
procedure’ as defined.
101 The CLFPA does not purport to regulate all forensic procedures per se; rather
it only governs the carrying out of procedures defined as ‘forensic procedures’ in
s 3. It says nothing about the procedures to be followed in obtaining forensic
samples from inanimate objects found in public places. Contrary to the appellant’s
submissions, the Act does not go so far as to codify the manner by which police
are required to obtain all forensic samples. Accordingly, the seizure of the
appellant’s discarded coffee cup from which his DNA profile was extracted did
not engage the provisions of the CLFPA.
102 The appellant has not identified any other law purportedly contravened by
police. The appellant discarded his coffee cup in a public place. There was no
suggestion it was obtained by trickery or by the provision of any misleading
information. There is no basis to find that police seizure of the coffee cup, and the
appellant’s subsequent extraction of a DNA sample from it, was unlawful or
improper such as to enliven the exercise of the Bunning v Cross discretion.
103 Given that the seizure of the coffee cup does not constitute a ‘forensic
procedure’ for the purposes of the CLFPA, we are also satisfied that s 47 does not
govern the question of the admissibility of the DNA evidence.
104 As to the appellant’s complaint that the DNA evidence should have been
excluded on the basis that the prosecution could not establish the chain of evidence,
nor exclude the risk of contamination beyond reasonable doubt, there was
sufficient evidence before the jury capable of establishing both matters. There was
a vast amount of evidence adduced by the prosecution as to the movement of the
crime scene samples, and on the issue of potential contamination. Those matters
were also the subject of considerable emphasis in the addresses of counsel. The
issue of whether those matters were proven beyond reasonable doubt was a
question for the jury.
-- 31 of 90 --
[2023] SASCA 80 The Court
28
105 For those reasons, we refuse permission to appeal on Ground 2A.
Ground 2 – Directions on the prosecution blood and DNA deposition evidence
106 The appellant complains that the trial Judge failed to instruct the jury that
they had to find both the chain of evidence and the exclusion of the risk of
contamination of the crime scene samples proven beyond reasonable doubt, as both
matters were indispensable intermediate findings in proof of the offence of murder.
107 The trial Judge gave a Shepherd direction14 in respect of the evidence he
compendiously referred to as the ‘blood and DNA deposition evidence’ and
instructed the jury that it was an intermediate fact which formed an indispensable
basis for an inference of guilt such that it must be proven beyond reasonable doubt.
The appellant complains that the trial Judge erred in not further directing the jury
that the chain of evidence, and exclusion of contamination of the crime scene
samples, had to be proven beyond reasonable doubt. In considering that contention,
it is necessary to set out the trial Judge’s directions in full. His Honour said:
Now, ladies and gentlemen, I have already given you detailed directions about
circumstantial evidence. I am not going to go through all of that again, but I have just made
the point to you again that what we are dealing with, DNA evidence, is of course a type of
circumstantial evidence.
And I have given you the analogy of a rope with a number of strands in it and two of the
strands, let us say two of the strands here, are composed – I will make it simpler for you.
The rope has a number of strands. One of the strands is comprised by what I have termed
the “prosecution blood and DNA deposition evidence”. Now, the position here is slightly
different to the usual type of circumstantial evidence, and so I give you the further direction.
I have previously said that in most cases of circumstantial evidence, it is not necessary to
look at any one strand of circumstantial evidence individually and find that strand proven
beyond reasonable doubt before you can consider it together with the other evidence in the
case. Usually you look at all of the evidence taken together and then decide whether the
case is proven beyond reasonable doubt.
However, in the present case, the prosecution blood and DNA deposition evidence strand
is, indeed, a very major part of the prosecution case. There are other strands, and I will
mention them and you can think of a few, but the prosecution blood and DNA deposition
strand is a very major part of the prosecution case. Accordingly, I direct you that you may
only act on the DNA statistical evidence, or the likelihood ratios, you have heard about if
you are satisfied of the accuracy and reliability of the prosecution blood and DNA
deposition evidence beyond reasonable doubt.
So the prosecution blood and DNA deposition evidence has got to be proven beyond
reasonable doubt and if it is not,15 then that would be an end of the case, really.
If it is,16 that is not an end of the case. It is proven beyond reasonable doubt, but you still
go on to say ‘Right, I take that prosecution blood and DNA deposition evidence that I have
found established beyond reasonable doubt as one strand’. I now look at other strands I am
prepared to find established (but not within themselves beyond reasonable doubt, as you
14 See Shepherd v The Queen (1990) 170 CLR 573.
15 Emphasis original.
16 Emphasis original.
-- 32 of 90 --
[2023] SASCA 80 The Court
29
will understand), and put them in the rope. ‘Does the entire rope, consisting of the blood
and DNA deposition strand, together with what other strands I consider should be there,
does that rope mean that the accused is to be found guilty on the basis of proof beyond
reasonable doubt?’ Or, in other words, that the charge of murder is proven beyond
reasonable doubt on the basis of that combination of circumstantial evidence.
Now, in order to be satisfied beyond reasonable doubt that the prosecution blood and DNA
deposition evidence is proven, you need to look at a number of things when you are
determining whether the likelihood ratios you are asked to act upon are accurately
calculated. And so, you do need to look at the process of taking of samples, storage of
samples, analyses, and determine whether the evidence proves the safety of that process
and the accuracy of that process beyond reasonable doubt.
I direct you in that way because I consider that it is an essential step in reasoning in this
particular case and, indeed, that the prosecution asks you to follow that process here, in
order to establish its case. Accordingly, that all means that unless the “prosecution blood
and DNA deposition evidence” is so proven beyond reasonable doubt, the reasoning relied
upon by the prosecution must fail and you would return a verdict of not guilty.
However, as I say, if you are satisfied that the prosecution blood and DNA deposition
evidence has been proven beyond reasonable doubt, it would then remain for you to
consider the evidence of those likelihood ratios that you have heard in combination with
other prosecution evidence you consider to be established when ultimately considering
whether the prosecution has proven the accused’s guilt beyond reasonable doubt.
(emphasis added)
108 During the course of the trial, defence counsel sought a direction that each
link in the chain of evidence, and the exclusion of contamination of the crime scene
samples (either at the crime scene or at FSSA), had to be excluded beyond
reasonable doubt. The trial Judge declined to direct the jury in that manner and
considered that the two issues did not need to be separated out, but rather, could
be subsumed within the one direction.
109 The appellant now submits that for the blood and DNA deposition evidence
to be proven beyond reasonable doubt, the jury had to be satisfied that the chain of
evidence was complete and that the samples were not contaminated. As such, both
matters were indispensable intermediate facts and it was necessary for the jury to
find both matters proven beyond reasonable doubt.
110 Moreover, the appellant contends that there was an insufficient nexus
between the trial Judge’s Shepherd direction, on the one hand, and the
requirements of proof beyond reasonable doubt of the links in the chain of evidence
and the exclusion of contamination, on the other. Accordingly, the direction was
inadequate.

111 In Nasaris v The Queen,17 this Court had regard to the authorities governing
the circumstances in which it may be necessary and appropriate to give a Shepherd
direction. The Court said:18
The authorities governing the circumstances in which it may be necessary or appropriate
to give a Shepherd direction were recently summarised by this Court in R v Singh.19 It is
not necessary to repeat that summary. It is sufficient to observe that:20
In determining whether, in a particular circumstantial case, a Shepherd direction is
appropriate, it will be necessary to consider the role and significance of the particular
evidence or fact in respect of which the direction is said to be appropriate. If, by
reason of either the inherent role or significance of that evidence or fact in the case,
or in light of the way in which the case has been conducted, it forms an indispensable
link in the chain of reasoning towards the defendant’s guilt, then such a direction
may be appropriate.
112 It is to be accepted that the trial Judge was required to give a Shepherd
direction in relation to the blood and DNA deposition evidence. The trial Judge
had earlier set out for the jury what he meant by the terms ‘blood and DNA
deposition evidence.’ His Honour said:
For reasons that I will explain, the topic of blood is very important in this case for several
reasons, and I will take you through them, but it is intimately woven into an analysis of
DNA. Why is that so? Because in this particular case we are talking about DNA evidence
which on the prosecution case is derived from the deposition of blood by the killer, on their
case, at the crime scene. On their case, the killer nicks himself with the knife, he bleeds,
he deposits blood at particular points at the crime scene. I will take you through these, and
it is by taking a sample of those blood deposits and then analysing those samples for DNA
that DNA results come before you.
113 It is evident the trial Judge highlighted that on the prosecution case, the
significance of the DNA evidence, lay in the crime scene samples having been
extracted from bloodlike stains deposited at various locations between Mrs Poll’s
body in the rear office and the sole point of entry/exit to the newsagency.
114 On the prosecution case, the secondary source of blood (other than that
associated with Mrs Poll) was deposited by the offender after he had been injured
during the knife attack on Mrs Poll. The probative force of the evidence was
derived from the combination of the DNA results having been extracted from
bloodlike stains, and the location of those stains in a path from Mrs Poll’s body to
the only operable entry/exit to the store.
115 The trial Judge explained to the jury the process by which a likelihood ratio
is obtained; that is, by a DNA profile being extracted from a crime scene sample
and compared with a DNA profile obtained from a reference sample provided by
a person of interest, thus resulting in a likelihood ratio. His Honour then said,

‘[t]hat is why I am going to refer to it by this compendious title of “prosecution
blood and DNA deposition evidence”’.
116 As part of its case, the prosecution adduced detailed evidence relating to the
chain of evidence on the incriminating DNA samples and as to the issue of the
possibility of contamination. For example, to rebut the defence case regarding
contamination of the DNA samples, the prosecution led evidence that, prior to the
appellant’s DNA sample being submitted to FSSA, there were no pre-existing
DNA reference samples relating to him stored in the laboratory. The prosecution
also adduced evidence from the point of the identification recording and collection
of samples by the crime scene examiners, through to police movement of exhibits
(including to FSSA), through to the receipt, storage, evidence recovery, and DNA
analytical processes undertaken at FSSA. There was also detailed evidence led
about contamination minimisation measures undertaken as part of processing the
crime scene, and internally within FSSA. This included police and FSSA processes
for dealing with exhibits, samples, and overlapping issues about chain of evidence
and contamination, all of which went to the integrity of the DNA results.
117 At trial, defence counsel undertook a generalised attack upon the accuracy
and reliability of the DNA results based upon criticisms of crime scene collection
techniques, police exhibit movement and storage methods, and FSSA processes
for documenting analysis, movement, and storage of samples. Defence counsel
did not contest the accuracy of the DNA results per se in that there was no
challenge to the accuracy of the profiles obtained, or the calculated likelihood
ratios. Rather, the challenge was confined to the chain of evidence, alleging that
the possibility of contamination of the crime scene samples had not been excluded
beyond reasonable doubt.
118 The trial Judge’s directions expressly linked the requirement of proof beyond
reasonable doubt of the prosecution blood and DNA deposition evidence to an
acceptance by the jury of the accuracy and reliability of the evidence. Proof of the
chain of evidence and exclusion of contamination directly informed the accuracy
and reliability of the blood and DNA deposition evidence. Given the manner in
which the trial was conducted by both parties, the jury could have only understood
the reference to the accuracy and reliability of the evidence as a reference to being
satisfied beyond reasonable doubt as to the chain of evidence and the exclusion of
contamination of the crime scene samples. For those reasons, additional directions
of the kind sought by the appellant were not warranted.
119 We are satisfied the directions were adequate. We dismiss this ground of
appeal.
Grounds 3 and 3A – Evidence of M
120 Grounds 3 and 3A relate to the admission of the evidence of M. Ground 3A
alleges that the trial Judge erred in admitting the evidence of M or, alternatively,
in failing to exclude the evidence in the exercise of the Court’s discretion. Ground
3 concerns the trial Judge’s directions as to that evidence. There are four limbs to
-- 35 of 90 --
[2023] SASCA 80 The Court
32
the appellant’s complaint. First, M’s evidence of the Warrnambool conversation
exculpated the appellant in that it tended to prove that Mrs Poll was killed by
another person (her husband, Darryl Poll) and the jury was not directed as to the
exculpatory use of the evidence. Second, the jury was not directed that it was
necessary to be satisfied beyond reasonable doubt that the Warrnambool
conversation related to Mrs Poll. Third, the trial Judge’s directions as to the
appellant’s purported lie were flawed in that they did not refer to the part of that
evidence where the appellant’s credibility arose for consideration. Fourth, that the
trial Judge did not adequately present the defence case on the exculpatory
statements; this contention is considered under appeal Ground 4.
121 In considering those complaints, it is necessary to set out the relevant
evidence adduced at trial in greater detail.
122 M commenced a relationship with the appellant around June 2019. The
relationship ended in the week prior to the appellant’s arrest in September 2019.
M gave evidence that the Warrnambool conversation took place in July 2019. She
said that she and the appellant had been to a restaurant for a meal and had returned
to her house. She said that she was talking about the fact that she had been single
for several years and, during that time, was pursued by a married man. She said
that she had consumed five alcoholic ciders between 7:30pm and about 10:00pm;
and she was more than ‘a little bit tipsy.’
123 M said that her and the appellant moved into the bedroom, whereupon the
appellant gave the following account of an experience he had as a young man:
He said that there was a woman that was much older than him that was after Miffy and he
said that - he started to talk about - he said that she was married, that she was a lot older
than him and then he started to talk about the sex that they had. He said she liked it with
her legs up, that she liked it up against things and that she was petite, she was a little thing.
And I asked if the sex was more exciting because she was married but I had noticed when
he started to talk about this that his - his just demeanour had changed and his head was
down and he was starting to look sad. I asked him if the sex was more exciting, given that
this was sort of a fairly innocuous conversation previously and he said 'No, it was just sex'
and then he said that it wasn't worth it and I thought - I was a bit confused by that and he
said that she wasn't very attractive and then he put his head in his hands and he was - had
moved from being up near the pillow end of the bed on his side of the bed to closer to me,
I was standing at the door - inside of the door near the wardrobe and he sat on the edge on
the corner of the bed and he put his hands in his head and he said that she liked it rough
and that she asked him to do things. And then he moved around, I had a chair near a window
where I put clothes on and he moved around to the bed - to the chair, sorry, and he stood
there and he said 'She started telling me all this shit' and then he said 'And she was
frightened, she was frightened that her husband would find out' and I said that she would
be, because, you know, she would be frightened he would find out and he said 'No, she was
frightened of him and she was petrified'. Then he moved over on my side of the bed and
the conversation was a bit more rapid at this point and he said 'And there was another guy
involved', I don't think he used the word 'involved' but he said there was someone else and
that this guy was holding it over her, that he was going there and asking her for money. He
said there was a lot of drugs around. He said that - and then his brother found out and he
put his head in his hands and shook his head. He said 'The other guy was big and scary and
a major drug dealer'. He said that her husband took drugs as well, he said they did drugs
-- 36 of 90 --
[2023] SASCA 80 The Court
33
and there was drugs around. He said that the major drug dealer, the scary guy, said there
was a lot of speed around and he said they did it together. Then he went back to the chair
and he said 'She was frightened' and he said - and then - she was frightened her husband
would find out and he said 'He did find out and he knifed her and they never got him for it'
and then he walked over to me and I said 'How did you meet this woman?' and he said he
met her - he said 'Well, she worked in a shop and I used to go in there and one night she
asked me to come back and I did' and I said 'How long did that go on?' and he said 'Not
even a couple of months'. And I was feeling very drained and tired at this point and
overwhelmed and I could see he was very sad and drawn and sort of weary looking and he
walked around and he got into bed and by that stage I had also walked around and got into
bed and he was straight to sleep, which was normal really for Matt, and I laid there for a
little while feeling overwhelmed and went to sleep.
124 M said that after the appellant’s arrest, she visited him at Yatala Labour
Prison twice on the weekend of 26 and 27 October 2019. During the second visit,
which lasted for about half an hour, she spoke with him at the visiting room. She
gave evidence about their conversation (‘the Yatala conversation’):
I said to Matt that I had come to tell him something, that I had - I asked him if he
remembered when I was talking about having affairs and the conversation and he said 'No',
and he said I could lean in and whisper what I needed to tell him. So I went to lean in and
as I leant in, he said 'I never had sex with her'. And I said 'That's not what you told me'.
And I then - then we were close - we were close (INDICATES) and I said to him - I
whispered to him that 'You told me about an affair with Suzanne, you told me about the
standover man and that her husband knifed her'. Then we pulled apart and he asked me -
he said 'Who have you told?', and before I got a chance to say anything, he asked - he said
'My brothers?', and then I shook my head to say no, to indicate no. And then he said 'The
police?', and I shook my head to indicate 'No'. And then I said ‘The lawyer'.
125 In cross-examination, it was put to M that the appellant said the woman with
whom he was having an extramarital affair was ‘Vanessa.’ M responded that there
were no names mentioned, including Mrs Poll’s name. Defence counsel also put
to M, that there was no conversation about a woman being knifed to death; she
disagreed.
126 M agreed that after learning of the appellant’s arrest, and before recounting
the detail of the Warrnambool conversation to anyone, she did an internet search
as to the charges the appellant faced and the ‘cold case’ of Mrs Poll. It was not
suggested at any stage to M that there was no such conversation; rather, defence
counsel challenged two aspects of it, namely that there was a reference to
‘Vanessa’ and that there was no reference to the woman being knifed. Defence
counsel ultimately submitted that the conversation was not referable to Mrs Poll
but another woman.
127 Mrs Poll’s husband, Darryl Poll, was also a prosecution witness at the trial.
Mr Poll gave evidence-in-chief, relevantly, as follows:
(a) Mr Poll was born and grew up in Adelaide. In the early 1980s he moved
to Sydney. He met Mrs Poll in Sydney.
(b) In 1984, Mr Poll and Mrs Poll were married.
-- 37 of 90 --
[2023] SASCA 80 The Court
34
(c) In the middle of 1988, Mr and Mrs Poll and their children moved from
New South Wales to South Australia.
(d) From Mr Poll's perspective, his marriage to Mrs Poll was a 'happy one'.
(e) In the early part of 1993, Mr Poll smoked marijuana about once a week,
on the weekends. He grew marijuana plants for the purpose of smoking
marijuana.
(f) After 9:15 pm on 29 April 1993, Mr Poll became concerned when
Mrs Poll had not returned home from work. He telephoned the
newsagency but there was no answer. He also telephoned Mrs Poll's
sister, Barbara Taylor, in case Mrs Poll had stopped at her sister's home,
but she had not. After 9:30pm, Mr Poll drove to the newsagency. He
saw Mrs Poll's car parked in a car park near John Street. Mr Poll saw
that the lights inside the newsagency were illuminated. The door to the
store was shut but not locked. Mr Poll entered the store and discovered
his wife's body lying on the floor of a staff office area behind the
counter. After attempting to resuscitate his wife, without success,
Mr Poll telephoned the 000 emergency service.
128 Defence counsel cross-examined Mr Poll briefly. Mr Poll confirmed that he
had a 'good marriage' with Mrs Poll. He was not aware of any affair between his
wife and another person. He and Mrs Poll had not had any 'major falling-out'.
129 The prosecution also called Barbara Taylor, the sister of Mrs Poll.
Mrs Taylor gave evidence-in-chief that in 1987 or 1988, Mr and Mrs Poll moved
from New South Wales to South Australia. After that time Mrs Taylor visited
Mrs Poll and her family regularly, 'probably once a week'. She observed the
relationship between Mr and Mrs Poll. They were 'happy' and 'got on well
together'.
130 Defence counsel did not cross-examine Mrs Taylor.
131 As discussed earlier, Detective Huppatz was the police officer with primary
responsibility for investigating Mrs Poll's death. Detective Huppatz said in
cross-examination that there was no evidence that he could find 'that there was
ever any suggestion that [Mrs Poll] was having an affair or being unfaithful to her
husband'.
132 Myfwanny Young, a former partner of the appellant, also gave evidence at
the trial. Ms Young gave evidence that in the early 1990s she had a
girlfriend/boyfriend relationship with the appellant. The relationship came to an
end sometime after the appellant's 21st birthday in November 1993. As at
November 1993, the appellant and Ms Young had been in a relationship for a
couple of years.

133 The prosecutor tendered, as part of the prosecution case, recordings of
telephone conversations between the appellant and members of his family while
the appellant was remanded in custody. Those conversations contained some
exculpatory statements by the appellant and some admissions by him. The
appellant stated that he was not responsible for Mrs Poll's murder. He was not
present at the newsagency when she was attacked. The appellant acknowledged,
however, that he knew of the newsagency, he had been in the store and his mother
lived in the vicinity of the store. He told his former wife, Lucy Tilley, that the
store was ‘more like a stationery shop than a newsagency.’21
The prosecutor's closing address at the trial
134 The prosecutor told the jury, correctly, in her closing address that the
elements of the offence of murder do not require proof of motive.
135 The prosecutor commented that it was natural, in a case of this kind, to
consider the ferocity and cruelty of the attack on Mrs Poll. The prosecutor then
said that it was natural to think that 'someone with a great deal of personal hatred
for [Mrs Poll] must have committed this crime'. That was an expectation based on
'so much of what we know about human beings'. The prosecutor added that 'human
beings … can be unpredictable' and they 'can act without motive or for reasons
known only to themselves'.
136 The prosecutor told the jury that she did not 'pretend for a moment to suggest
why Mrs Poll was killed or why she was killed in the way she was but if [the jury
were] asked to place much stock in the fact that [the appellant] apparently had no
motive to kill her', the prosecutor asked the jury 'to reflect on what [the jury knew]
about the unknowns of human behaviour'. The prosecution's position was that,
even without the appellant having an apparent motive, there was no reasonable
view of the evidence that was consistent with the appellant being innocent of the
crime of murder. The prosecutor then elaborated:
On what you know about [Mrs Poll's] life there is no obvious candidate with a motive to
kill her, much less to kill her in this very violent manner. The weight of the evidence
reveals [that Mrs Poll] was happily married, supported by her family and committed to her
job. The point is not to say she could not possibly have had any enemies but rather to
highlight the absence of anyone having an obvious motive to harm her. That is just another
way of making the point that the absence of motive is not the be-all and end-all of
determining a charge of murder because sometimes there is just no explicable reason for
why things happen as they do.
137 The prosecutor submitted that the recorded telephone conversations between
the appellant and members of his family revealed that the appellant knew of the
newsagency and had been in the store. He appeared to know enough about the
store to tell his former wife, Lucy Tilley, that the store was more like a stationery
shop than a newsagency. The prosecutor then emphasised to the jury that when
they were considering the prosecution's contention that the DNA analysis and
21 Emphasis added.
-- 39 of 90 --
[2023] SASCA 80 The Court
36
likelihood ratios strongly supported the identification of the appellant as the source
of the male blood at the crime scene, the jury should not look at the DNA evidence
in 'complete isolation'. Rather, the jury should look at the DNA evidence 'within
this broader fabric of [the appellant] having … other connections to the location'.
Those connections included the appellant's mother, Ms Richardson, living in the
vicinity of the store. The prosecutor also submitted that the relevant connections
included M's evidence as to the conversation she had with the appellant in
Warrnambool about the appellant having had 'an affair with an older married
woman who worked in a shop and who was knifed to death'. The prosecutor
reiterated that the prosecution's case was circumstantial in nature and consequently
it was 'important to look', and the jury was 'entitled to look', at the combined effect
of all of the evidence. The prosecutor added that, nevertheless, 'the DNA evidence
has a particular importance in this case'.
138 The prosecutor repeated the substance of M's evidence as to her conversation
with the appellant at Warrnambool and made detailed submissions about that
evidence. In particular:
(a) The prosecutor submitted that if the jury accepted M's evidence
concerning the Warrnambool conversation and if the jury found that
Mrs Poll was the married woman to whom the appellant referred, it
would be open to the jury to conclude that the appellant was claiming
to have some connection with Mrs Poll, that the appellant was speaking
about the circumstances of Mrs Poll's killing and that the appellant was
showing an interest in Mrs Poll and her murder.
(b) The prosecutor reminded the jury of M's evidence as to the content of
the Warrnambool conversation, including:
(i) the appellant said the married woman was frightened that her
husband would find out about their affair and that the husband 'did
find out and [the husband] knifed her and they never got him for
it';
(ii) the appellant said the woman worked in a shop and explained that
he would go to the shop and one night she asked him to come
back, and he did;
(iii) the appellant said the affair did not last even a couple of months
and at that point in the conversation the appellant was very sad
and drawn and looked weary;
(iv) M believed what the appellant told her that night; and
(v) M rejected defence counsel's suggestion that nothing had been
said in the conversation about the woman being knifed or killed.
-- 40 of 90 --
[2023] SASCA 80 The Court
37
(c) The prosecutor submitted that the Warrnambool conversation was an
'inherently memorable conversation' for M and that M's memory of the
conversation was vivid.
(d) The prosecutor submitted that it was highly unlikely that, after carrying
out internet searches about the appellant's arrest, M 'somehow reverse
engineered a conversation about affairs and a married woman who
worked in a shop who was knifed to death'.
(e) The prosecutor acknowledged that there was no evidence in the trial or,
according to Detective Huppatz, arising in the investigation, that
Mrs Poll had been engaged in an extramarital affair. However, the
prosecutor explained that the prosecution did not point to M's evidence
as proof of an affair between the appellant and Mrs Poll. The
prosecutor said that what was significant, if the jury accepted M's
evidence, is that in the middle of 2019, some 26 years after Mrs Poll
was killed, the appellant was talking about a married woman who
worked in a shop, who was knifed to death and 'the culprit got away
with it'22
(f) The prosecutor submitted that, even if 'the claimed affair is a complete
embellishment', the appellant was claiming to have had an association
with a married woman. The prosecutor contended that the features of
the conversation could lead the jury to draw the inference that the
appellant was speaking about Mrs Poll. The relevant features were that
the appellant was talking about an older woman; the woman was
married; she worked in a shop; he used to go into the shop; the woman
asked him to come back one night; the woman was knifed; and the
police 'never got the person for it'.23 The prosecutor submitted that the
events of which the appellant spoke in the conversation were 'after
Miffy, take that to be Myfwanny Young, which puts it in the ballpark
of 1993, or at least thereabouts'.
(g) The prosecutor acknowledged that there were points of difference
between what the appellant said in the Warrnambool conversation and
what the jury knew of Mrs Poll's life but, according to the prosecutor,
'the key features are so aligned that [the appellant] must have been
talking on the topic of [Mrs Poll] and the circumstances of her killing'.
The prosecutor suggested that 'the details of a married woman who
worked in a shop being knifed to death, bring this matter that [the
appellant] was talking about within a fairly narrow compass'. The
prosecutor added that when the appellant 'talks about it being a shop he
used to go into, the compass is even narrower'.
22 Emphasis added.
23 Emphasis added.
-- 41 of 90 --
[2023] SASCA 80 The Court
38
(h) The prosecutor said that if the jury accepted that the appellant was
'talking on the topic of [Mrs Poll], then it is clear that in [the
Warrnambool] conversation … he was claiming to have some
connection to her'. The prosecutor then said that the Warrnambool
conversation, if the jury accepted it, was 'capable of connecting [the
appellant] to [Mrs Poll] through his own statements, statements which
are completely separate to the forensic evidence at the crime scene'.
(i) The prosecutor submitted that the appellant was saying to M, 'I knew
this woman. She was knifed and I knew her'. The prosecutor then said
that if the jury accepted that this is what the appellant was saying to M,
namely 'that he knew this woman or had some connection to her, then,
in the prosecutor's submission, [the jury] can look at the DNA results in
that light'.
(j) The prosecutor posed the question, 'what are the chances of a
contamination event?' in relation to the DNA results. The prosecutor
elaborated, specifically, '[a] mix up of samples, a mix up of tubes, or
anything along those lines in relation to a crime scene that is not only
nearby to [the appellant's] mother's house, not only frequented by him,
but the scene of the killing of a woman who he talks about 26 years after
the event?'. The prosecutor said that it would be 'a coincidence beyond
comprehension that crime scene and/or laboratory error in relation to
samples implicating [the appellant] took place in respect of a crime
which he happens to speak about with a new girlfriend in another State
all those years later'.
(k) The prosecutor told the jury that the jury was 'entitled to look, and in
the prosecution's submission [the jury] must look, at the evidence in its
entirety'. The prosecutor then said '[t]he DNA results, in conjunction
with the human blood testing and blood pattern analysis, provide sound
evidence for a conclusion that [the appellant] bled in that shop' and that
it was 'a shop he knew, in a suburb in which he had lived and to which
he remained closely connected through his mother'.
139 The prosecutor made only a brief passing reference in her closing address to
the conversation between M and the appellant at Yatala Labour Prison. The
prosecutor merely said, in the course of recounting M's evidence as to the
Warrnambool conversation, that M 'did not speak to [the appellant] about this topic
again until she visited him in Yatala on 27 October 2019'.
140 The prosecutor did not refer in her closing address to any alleged
inconsistencies between what the appellant told M (according to M) in the
Warrnambool conversation and what the appellant told M (according to M) in the
Yatala conversation.
-- 42 of 90 --
[2023] SASCA 80 The Court
39
141 The prosecutor did not say to the jury in her closing address (or at any other
stage of the trial) that the appellant had lied in the Warrnambool conversation or
the Yatala conversation.
Defence counsel's closing address at the trial
142 Defence counsel told the jury in her closing address that the jury had to be
satisfied that the Warrnambool conversation was actually about Mrs Poll. The jury
also had to be satisfied that M was not an honestly mistaken witness.
143 Defence counsel referred to M's evidence as to the content of the
Warrnambool conversation and submitted:
This was a conversation [in about July 2019] and lo and behold, after 26 years, a couple of
months after this very conversation, a few months later, police come and talk to [the
appellant]. You might think that's a very unusual coincidence. … So, six weeks into this
relationship, in a conversation about affairs, [the appellant] is supposed to have mentioned
this woman who later turns out to be highly relevant just a few months later and it's
[Mrs Poll]. What a coincidence. Too big a coincidence.
144 Defence counsel noted the evidence of Mr Poll to the effect that there was
'no falling out or anything of that kind' between Mr and Mrs Poll. Defence counsel
also noted the evidence of Mrs Taylor and what she had observed about the
relationship between Mr and Mrs Poll. Defence counsel also noted Detective
Huppatz's evidence that he could find no evidence of an affair by Mrs Poll.
145 Defence counsel then said that, somehow, '[the appellant] is the one person
talking about an affair with [Mrs Poll]'. Defence counsel suggested that it was
quite possible that M had 'got things mixed up'.
146 Next, defence counsel referred to 'the timing of this so-called alleged affair
with [Mrs Poll]'. Defence counsel submitted that the timing of the affair that the
appellant was talking about in the Warrnambool conversation was, in fact, 'after
[Mrs Poll] is dead because it's after Miffy [that is, Myfwanny Young] and Miffy's
evidence was that she was still in a relationship with [the appellant] at least in
November of 1993'.
147 Defence counsel mentioned M's visit to Yatala Labour Prison in October
2019 and her evidence about the conversation she had with the appellant on that
occasion. M gave evidence that the appellant said, 'I did not sleep with her'.
According to M, the appellant then looked worried about what she was raising and
wanted to know 'who have you told this to?'. Defence counsel submitted that the
appellant's reaction was consistent with someone who was thinking, 'what she's
saying is not right'.
148 Next, defence counsel referred to the recorded telephone conversations
between the appellant and members of his family, including conversations on
30 December 2019 (after M's visit) in which the appellant said, 'I did not do this.
I don't even know these people. I'm not guilty. It's not what you think.'.
-- 43 of 90 --
[2023] SASCA 80 The Court
40
149 Defence counsel suggested that the jury might not be able to accept that
M was necessarily correct in her evidence about the Warrnambool conversation.
Defence counsel also said:
Anyway, at the end of the day, you might think if [the appellant was] talking about an affair
that took place after Mrs Poll's death, then it can't be an affair with Mrs Poll.
150 Defence counsel submitted that the jury could not accept the prosecutor's
suggestion that M's evidence showed a connection between the appellant and
Mrs Poll unless the jury accepted that M had 'got that conversation right'. Defence
counsel added that the jury should take into account that there was 'no evidence of
an affair' by Mrs Poll and that '[i]t just doesn't stack up'.
151 Defence counsel did not refer in her closing address to any alleged
inconsistencies between what the appellant told M (according to M) in the
Warrnambool conversation and what the appellant told M (according to M) in the
Yatala conversation.
Ground 3A – the admissibility of the evidence of M
152 The appellant complains that the trial Judge erred as a matter of law in
admitting the evidence of M; or alternatively, erred in declining to exclude the
evidence in the exercise of the Christie discretion. 24
153 As outlined above, the prosecution alleged that the Warrnambool
conversation established a ‘connection’ between the appellant and Mrs Poll
independent of the forensic evidence at the crime scene. The salient features of the
appellant’s conversation included:
(a) There was a married woman who was much older than him.
(b) She worked in a shop which he used to go into and one night she asked
him to come back, and he did.
(c) They had sex.
(d) It went on for several weeks.
(e) The woman was frightened that her husband would find out.
(f) The woman’s husband found out and knifed her and they never got him
for it.
154 The prosecutor submitted that the appellant was referring to Mrs Poll by
reason of the following details: Mrs Poll was a married woman; she worked in a
shop which he used to go into; the forensic evidence suggested she died as a result
of a knife attack; and the police never apprehended any person for the offence. It
was also submitted that it was relevant that the appellant admitted in other recorded
24 See R v Christie [1914] AC 545.
-- 44 of 90 --
[2023] SASCA 80 The Court
41
conversations that he had been into the newsagency, or ‘shop’, where Mrs Poll
worked (but denied being present for, or having committed, the offence). The
prosecutor put to the jury that it did not matter whether the appellant had in fact
engaged in a sexual relationship with Mrs Poll or whether this was an
‘embellishment’; the relevance of the conversation was that it was capable of
establishing a connection, or link, between the appellant and Mrs Poll, separate
from the crime scene and blood and DNA deposition evidence; and the appellant
was discussing, or claimed a connection with Mrs Poll 26 years after her death,
and before he was made aware that he was a suspect in her murder, and at a time
when there was no apparent reason to be discussing her.
155 Defence counsel objected to the admission of the Warrnambool conversation
at trial.
156 The appellant contends that the evidence was wrongly admitted and resulted
in a miscarriage of justice. He submits the conversation had limited probative force
given those aspects which suggested it was not referable to Mrs Poll. Further, the
appellant submits that the jury would need to first accept that the appellant had a
sexual relationship with Mrs Poll for the evidence to have any relevance; a false
connection could not, as a matter of logic, assist in resolving the issues at trial.
Thus, the evidence carried with it an implied assertion that the appellant’s
representation to M was true. That being so, the appellant contends that the
impugned evidence was either inadmissible (as being not referable to Mrs Poll) or
should have been excluded in the exercise of the Christie discretion as it was more
prejudicial than probative (Ground 3A.1).
157 For the reasons which follow, we are satisfied the evidence was properly
admitted.
158 The evidence derived from the appellant’s utterances of his connection with
Mrs Poll at a time before he knew, or could have known, that he was suspected of
her murder was considerably probative. It mattered not whether the appellant had
in fact engaged in an affair with her; it was his claim of a connection to Mrs Poll
some 26 years after her murder which was probative in establishing a link between
her and the appellant, and that she was still on his mind, as a relevant piece of
circumstantial evidence in proof of his guilt.
159 There was sufficient detail in the alleged narrative to link the Warrnambool
conversation with Mrs Poll, namely: that she was an older woman who worked in
a shop and was knifed to death, and the alleged offender (who the appellant
claimed was her husband) was never apprehended. These are unusual matters
which do not happen commonly or frequently in the experience of most people.
160 Against that, it is to be accepted that there was evidence adduced as part of
the prosecution case that Mrs Poll was not having an extramarital affair; that her
husband’s shoe impressions were inconsistent with the unidentified shoeprints at
the crime scene; and the timing of the affair (as allegedly recounted by the
-- 45 of 90 --
[2023] SASCA 80 The Court
42
appellant) would mean it occurred after the murder by reference to the timing of
his relationship with Ms Myfwanny Young.
161 Notwithstanding that those matters were all relevant to the jury’s
determination as to whether they accepted the Warrnambool conversation related
to Mrs Poll, there was a sound basis for the jury to accept the veracity of M’s
account of the conversation, and to accept that the appellant was referring to
Mrs Poll. The jury were also properly instructed that it was open to them to accept
some of the appellant’s assertions while rejecting others and to conclude that the
appellant had a connection with Mrs Poll, even if they were not satisfied that the
appellant had in fact had a sexual relationship with her.
162 If the jury accepted M’s account of the Warrnambool conversation and
accepted that the appellant was referring to Mrs Poll, that was a piece of
circumstantial evidence in support of the prosecution case as to the identity of the
offender. The evidence did not go so far as to provide evidence of motive, but it
did establish a connection between the appellant and Mrs Poll separate and distinct
from the crime scene evidence. It had considerable probative value in proving that
the appellant was the offender.
163 The prejudicial effect of the evidence was that the appellant allegedly had a
sexual affair with a married woman, and there was potentially a risk that the
evidence would be misused as providing a motive for the offence. However, any
prejudice arising from that evidence was capable of being cured by directions
(which were ultimately given by the trial Judge) and did not outweigh the probative
force of the evidence.
164 We are satisfied the evidence was admissible and the trial Judge did not err
in declining to exclude the evidence in the exercise of his discretion.
165 Under this ground of appeal, the appellant also makes the aligned complaint
that the prosecutor, in her closing address, improperly urged the jury to use the
evidence of M to prove both the chain of evidence of the crime scene samples and
to exclude the risk of contamination, beyond reasonable doubt.
166 In her closing address, the prosecutor said:
If you accept that Matthew Tilley was talking on the topic of Suzanne Poll, then it is clear
that in that conversation in [M’s] bedroom he was claiming to have some connection to
her. That conversation, if you accept it, is capable of connecting Matthew Tilley to Suzanne
Poll through his own statements, statements which are completely separate to the forensic
evidence at the crime scene. In the prosecution’s submission, what he was saying to [M]
was ‘I knew this woman. She was knifed, and I knew her.’ If you accept that is what he
was saying to [M], that he knew this woman or had some connection to her, then, in the
prosecution’s submission, you can look at the DNA results in that light. What are the
chances of a contamination event? A mix up of samples, a mix up of tubes, or anything
along those lines in relation to a crime scene that is not only nearby to Matthew Tilley’s
mother’s house, not only frequented by him, but the scene of the killing of a woman who he
talks about 26 years after the event? It would be a coincidence beyond comprehension that

43
crime scene and/or laboratory error in relation to samples implicating this accused to a
place in respect of a crime which he happens to speak about with a new girlfriend in
another State all those years later. Members of the jury, you are entitled to look, and in
the prosecution’s submission you must look, at the evidence in its entirety. The DNA
results, in conjunction with the human blood testing and blood pattern analysis provides
sound evidence for a conclusion that the accused bled in that shop. It was a shop he knew,
in a suburb in which he had lived and to which he remained closely connected through his
mother.
(emphasis added)
167 At trial, defence counsel advanced the argument on behalf of the appellant
that the DNA results were not the consequence of him depositing blood in the
course of, or in connection with, the stabbing of Mrs Poll, but rather, that it was
the consequence of some contamination or error by police or FSSA handling and
processing of the relevant inculpatory samples.
168 At the appeal hearing, the respondent accepted that the evidence of M, as to
the Warrnambool conversation, could not directly disprove that there had been an
error in the processing of the crime scene, or in the laboratory work, leading to
contamination of the relevant crime scene samples. That is an appropriate
concession. The accuracy and reliability of the blood and DNA deposition
evidence stood to be assessed in isolation from the other circumstantial evidence.
The other pieces of circumstantial evidence, including M’s evidence, could not
assist in resolving challenges to the DNA evidence, nor could it exclude beyond
reasonable doubt the risk of contamination of the crime scene samples.
169 As Perry J said in R v Smith:25
It is true that in evaluating circumstantial evidence one’s view as to the probative value of
a particular item of circumstantial evidence which standing alone may not take the matter
very far, may be substantially enhanced when it is considered in conjunction with another
item of circumstantial evidence.
But as to the DNA testing it was first necessary for the jury to resolve the question as to
whether or not Ms Williams’ evidence or Dr Atchison’s evidence was to be preferred. In
resolving the conflict between the testimony of those two witnesses no assistance could
have been derived from any conclusion reached separately on a discreet [sic] body of
evidence which went to the question of whether or not the appellant was the person
responsible for the two other incidents.
170 The prosecutor urged the jury to look at the DNA results in light of the
Warrnambool conversation, and the purported connection between the appellant
and Mrs Poll, and suggested that in determining whether the blood and DNA
deposition evidence was proven beyond reasonable doubt, and whether a
contamination event was excluded beyond reasonable doubt, the jury could have
25 (1998) 71 SASR 543 at 559 per Perry J. See also R v IAS (2004) 89 SASR 159 at [104] per Besanko J;
R v Karger (2002) 83 SASR 134.
-- 47 of 90 --
[2023] SASCA 80 The Court
44
regard to other evidence in the case. That was an impermissible line of reasoning
and should not have been advanced.
171 It was only if the jury was satisfied beyond reasonable doubt of the blood and
DNA deposition evidence that they could then use the other pieces of
circumstantial evidence (including the evidence of M) in proof of the offender’s
identity as the appellant.
172 It is significant, however, that the comments made by the prosecutor and the
approach she urged upon the jury were not adopted by the trial Judge in his
summing up. His Honour gave comprehensive and appropriate directions about
the proper use of the blood and DNA deposition evidence (discussed in relation to
Ground 2) and as to the permissible and impermissible uses of the evidence of
M (discussed in relation to Ground 3A). That being so, we do not consider that
there has been any miscarriage of justice occasioned by the prosecutor’s impugned
comments in her closing address.
173 We grant permission to appeal on Ground 3A but dismiss the appeal.
Ground 3 - Directions as to M’s Evidence
174 The trial Judge commenced his directions by instructing the jury that they
may wish to proceed by first considering whether M was an honest witness. His
Honour then set out the detail of the Warrnambool conversation. His Honour
referred to defence counsel’s submissions as to M’s level of intoxication before
instructing the jury that alcohol may have adversely affected her ability to
comprehend and recall the conversation, and that her recollection could also be
affected by the effluxion of time.
175 The trial Judge then referred to, and commented in detail on, M’s evidence
as to her conversation with the appellant at Warrnambool.
176 His Honour directed the jury that, if the jury accepted M’s evidence as to the
Warrnambool conversation, the jury must not use the Warrnambool conversation
in two ways, which his Honour then described.
177 First, the jury must not use the evidence of the Warrnambool conversation to
find that what the appellant allegedly said in that conversation displayed 'some sort
of knowledge that only the killer could have had'. Second, the jury must not use
the evidence of the Warrnambool conversation to reason that the appellant was a
person of bad character because he was prepared to encourage adultery by a
married woman.
178 The trial Judge directed the jury that 'the only way in which you can use the
Warrnambool conversation against [the appellant] is as follows':
[I]f you accept that the Warrnambool conversation occurred as [M] testified then there is
evidence which, when taken together with other circumstantial evidence before you, could
-- 48 of 90 --
[2023] SASCA 80 The Court
45
found the inference that [the appellant] was then in his own mind referring to Mrs Poll
when he said these things even though, of course, he did not use her name.
179 His Honour then elaborated:
[Y]ou can take into account the Yatala prison calls that I will come to in a moment where
[the appellant] said most definitely that he had been in that very shop more than once. So
again, you have got evidence that he was acquainted with that shop, he had been in there
more than once and so if you add those things to the Warrnambool conversation, if you
accept it as [M] said it happened, you would be able to, if you so find, draw an inference
that [the appellant] was referring to Mrs Poll during the Warrnambool conversation even
though he did not use her name. If you draw that inference, then it is open to draw the
further inference that he did have some sort of connection with, or interest in, Mrs Poll in
some way or, indeed, some interest in her death in some way. I mean, as men and women
of the world again you will appreciate that if he did say the things that [M] says that he did
say, and he was then referring to Mrs Poll in his own mind, it does not necessarily follow
that what he said about actually having sexual intercourse with her was true. A claim that
he had had sexual intercourse with her may have been false. I mean, people tell falsities
about whether they have or have not had sexual intercourse with a particular person on a
fairly constant basis. So that aspect of what he said may be untrue. But, if untrue, the
inference may still remain that he had an interest in her and the fact that he was prepared
to claim that he had had intercourse with her may display the holding of such an interest,
talking about a person sexually.
180 Next, the trial Judge summarised M's evidence about her visit to Yatala
Labour Prison and the conversation she had with the appellant. His Honour then
summarised the recorded telephone conversations between the appellant and
members of his family.
181 His Honour then gave the jury directions about how the jury should proceed
if they were to conclude that the appellant told a lie during the Warrnambool
conversation, or the Yatala conversation with M or during any of the recorded
telephone conversations between the appellant and members of his family.
His Honour said:
For example, if you were to accept the evidence of [M] concerning both the Warrnambool
and Yatala conversations and you found that [the appellant] in the Warrnambool
conversations had been referring to Mrs Poll and the described sexual activity, then you
would be in a position of finding that [the appellant] has made two statements inconsistent
with each other. First, the statement in Warrnambool that he had sexual intercourse with
Mrs Poll. And then the later statement during the Yatala conversation that he did not have
sexual intercourse with Mrs Poll. It would seem that both of those statements, those
opposite statements, cannot be true.
So I just want to caution you not to make too much of a finding of the telling of a lie if you
so found. If you were to come to a conclusion that [the appellant] told a lie in any of the
conversations led in evidence before you, it is for you, it is for you to say what conclusion
you come to concerning such a lie.
I will give you this general direction, you should make up your own mind whether [the
appellant] told a lie and if he did whether he did so deliberately. It is for you to decide
what significance a lie may have in relation to the credibility of [the appellant] and the
issues in the case. I warn you, do not follow a process of reasoning to the effect that just
-- 49 of 90 --
[2023] SASCA 80 The Court
46
because a person is shown to have told a lie about something that is positive evidence of
his guilt of the offence charged against him. I emphasise that even if you made a finding
of lying by [the appellant], nevertheless the onus remains at all times on the prosecution to
satisfy you beyond reasonable doubt of each of the elements of the charge of murder.
182 The trial Judge then adjourned the trial until the following morning.
183 The following morning defence counsel raised with his Honour, in the
absence of the jury, the directions his Honour had given about lies. Defence
counsel said that she was 'a little uncertain' about the permissible, as opposed to
the impermissible, use of those lies.
184 The following exchange occurred between the trial Judge and defence
counsel:
HIS HONOUR: … I don't know if you recognise it or not, but I gave the direction
straight out of the High Court specimen direction as to what
should be given these days. I did so on the basis that one outcome
was that if the jury wholly accept the evidence of [M] then they
are faced with the situation where they have got two opposing
things said on two different occasions, if you will. Therefore,
they could find a lie and therefore it seemed to me best to give
the antiseptic direction recommended by the High Court.
[DEFENCE COUNSEL]: Thank you, and I do recognise that your Honour has given them
some direction about how not to use the lie. I suppose that leaves
an area, though, where they might think there is some other way
to use a lie in a case where
-
HIS HONOUR: Well no. It's not the way to use lies. I haven't directed as to lies
evincing a consciousness of guilt or anything else, far from it.
What I have directed on is the way in which you can and cannot
use the Warrnambool conversation and that wasn't in any way or
medium of finding lies, that was on a basis that you accept what
[M] said as to the conversation between her and [the appellant]
on that occasion, how you can use it or not use it.
When you, however, go further and you come to, for example,
the Yatala conversation and then you have the possibility of a lie
sort of emerging there I haven't in any way suggested how you
can use and not use lies. I've simply said the way that you would
approach a lie, if you found it to be established, was this, and then
given the verbatim High Court direction.
[DEFENCE COUNSEL]: May it please the court.

185 The 'High Court specimen direction' mentioned by his Honour was the
direction formulated by Gleeson CJ, Gaudron, Gummow and Callinan JJ in
Zoneff v The Queen (‘Zoneff’).26
186 The trial Judge directed the jury that unless the prosecution proved the blood
and DNA deposition evidence beyond reasonable doubt, the reasoning relied upon
by the prosecution must fail and the jury should return a verdict of not guilty.
187 His Honour also directed the jury that even if the prosecution proved the
blood and DNA deposition evidence beyond reasonable doubt, it would be
necessary for the jury to consider the evidence of the likelihood ratios in
combination with other prosecution evidence which the jury decided was
established 'when ultimately considering whether the prosecution has proven
[the appellant's] guilt beyond reasonable doubt'.
Ground 3.1 - No direction as to the exculpatory use of the statement
188 Under the first limb of Ground 3, the appellant complains that the trial Judge
erred by failing to direct the jury as to the exculpatory use of the Warrnambool
conversation. In so contending, the appellant relies on the authorities of
Castle v The Queen; Bucca v The Queen27 (‘Castle’) and R v Golubovic28
(‘Golubovic’).
189 In Castle, a wholly exculpatory statement was erroneously characterised as
an admission in circumstances where it was relevant to the defence case at trial
that the accused had not shot the deceased. This Court found there was an error
resulting in a miscarriage of justice but applied the proviso. The High Court held
that the error in characterising the exculpatory statement as an admission, when it
was in fact an exculpatory statement, gave rise to a perceptible risk of miscarriage
of justice and the proviso could not be applied despite the strength of the
prosecution case.
190 The present case can be distinguished on its facts. The appellant’s complaint
is that the trial Judge did not direct the jury as to the use it could make of the
exculpatory part of the appellant’s statement. It was not, however, the appellant’s
complaint that it was erroneously left as an admission.
191 In Golubovic, the appellant was charged with five counts of possessing child
exploitation material in relation to files found on a computer at his house. The trial
Judge gave no directions to the jury on the permissible and impermissible uses of
his denials made in a police interview. In allowing the appeal, Blue J held that it
was impossible to know what weight the jury may have given to the evidence had
a direction been given as to the exculpatory use of the denials.29 Justices Blue and
Peek, in separate judgments, placed considerable weight on the fact that the

[2023] SASCA 80 The Court
48
exculpatory statements were detailed and consistent with defence arguments put at
trial.
192 In the present matter, the appellant contends that embedded in the
Warrnambool conversation was an exculpatory statement to the effect that
Mrs Poll’s husband had killed her, which gave rise to a hypothesis consistent with
innocence; that is, a person other than the appellant was responsible for her death.
That being so, the appellant submits that the absence of a direction as to the
exculpatory use of the evidence resulted in a miscarriage of justice.
193 It is to be accepted that if the jury was satisfied of the truthfulness and
accuracy of the whole of M’s evidence, and that the appellant had been referring
to Mrs Poll, then in that conversation was an exculpatory statement that Mrs Poll’s
husband had ‘knifed’ her. However, the directions the trial Judge was required to
give as to the exculpatory statement were, to some extent, informed by the way in
which the trial was conducted by defence counsel. Further, the nature of the
statement was such that whilst attributing responsibility to another, the appellant
did not identify any basis for knowing about the suggested involvement of
Mrs Poll’s husband, apart from what it was Mrs Poll had apparently told him.
194 The thrust of defence counsel’s submissions at trial was that the
Warrnambool conversation related to another woman. Defence counsel did not
expressly place any reliance on the appellant’s alleged assertion that Mrs Poll’s
husband killed her. As outlined above, Mrs Poll’s husband, Darryl Poll, gave
evidence that his role was confined to finding Mrs Poll’s body after she did not
return home as expected. That evidence was never challenged. Indeed, when
cross-examining Mr Poll, defence counsel adduced evidence from him that he had
a good marriage to Mrs Poll, and he was unaware of any extramarital affair.
Defence counsel, in her closing address, also relied on the absence of any evidence
of an affair to suggest the conversation was not referable to Mrs Poll.
195 When directing the jury as to the permissible uses of the Warrnambool
conversation, the trial Judge did not specifically refer to the exculpatory use of the
evidence. However, earlier in his summing up, his Honour expressly instructed the
jury that:
… if at the end of the day you consider there remains, after looking closely at all of the
evidence, there remains the reasonable possibility that someone other than the accused
murdered Mrs Poll then, of course, you would have to acquit the accused.
196 This direction reflected the true effect and potential exculpatory use of the
evidence.
197 Earlier in his summing up, the trial Judge also referred to the appellant’s
denials in recorded telephone calls and directed the jury as to their exculpatory use.
His Honour instructed the jury that they ‘… can take into account those denials in
his favour should you wish to do so. It will be a matter for you as to how much
weight you place on those denials, entirely a matter for you.’
-- 52 of 90 --
[2023] SASCA 80 The Court
49
198 Moreover, later in his summing up, the trial Judge referred to the two groups
of evidence containing exculpatory statements, namely M’s account of the
Warrnambool and Yatala conversations, and the appellant’s denials during
recorded telephone calls, and again gave directions as to their exculpatory use. His
Honour said:
In terms of both of these groups that I have just outlined, both of the groups of evidence
the prosecution chose to tender the evidence about conversations and points to matters
therein that are said that it contends advance its case or are incriminating. That is all well,
but I direct you that you can use all or any parts of that evidence, both for and against the
accused as you see fit. You can have regard to statements and any of those conversations,
for example, that you think are, or may be, exculpatory in nature, they may help the
defendant. The mere fact that the prosecution has tendered this evidence does not mean that
you do not look at all of it and it does mean that you can use all or any parts of the evidence
both for and against the accused as you see fit.
You will remember in parallel here really my directions concerning witnesses, that you can
accept part of a witness’s evidence but not accept other parts. So it is in the present situation
of these statements or statements here being made by the accused. You can place different
weight on different parts of what the accused says in such circumstances. You may accept
some comments or statements he makes and reject others. You may also bear in mind, as
you look at this evidence, that exculpatory statements made by the accused in such
conversations were not made on oath and have not been tested by cross-examination in
court; that is something you can consider when deciding what weight to give to what parts
of these conversations.
199 Whilst the trial Judge did not expressly direct the jury as to the exculpatory
use of the appellant’s purported assertions during the Warrnambool conversation,
that use would have been obvious to the jury. Further, the jury were expressly
directed at other parts of the summing up that they were required to be satisfied
beyond reasonable doubt of the identity of the offender and exclude as a reasonable
possibility that another person had murdered Mrs Poll, which was the true effect
of the exculpatory statement. That being so, and taking into account that the jury
were also directed that they could have regard to the appellant’s denials of the
offending in the recorded telephone conversations, we are satisfied that the absence
of a specific direction as to the exculpatory use of the appellant’s assertion
embedded in the Warrnambool conversation, that Mrs Poll’s husband ‘knifed’ her,
did not amount to a miscarriage of justice.
Ground 3.2 – a direction that the jury need to make a finding beyond reasonable
doubt that the Warrnambool conversation was referrable to Mrs Poll
200 The appellant also complains that the trial Judge erred in failing to direct the
jury of the need to find proven beyond reasonable doubt that the Warrnambool
conversation was referable to Mrs Poll before they could use any part of it as
evidence of a lie.
201 The trial Judge in his summing up directed the jury as to how they should
proceed should they conclude that the appellant told a lie in either the
Warrnambool conversation, or during the Yatala conversation or during any of the
-- 53 of 90 --
[2023] SASCA 80 The Court
50
recorded telephone conversations. The trial Judge identified, as an example, that if
the jury was satisfied that the appellant was referring to Mrs Poll in the
Warrnambool conversation, there was an inconsistency between his statement
during that conversation that he had sexual intercourse with Mrs Poll, and his later
statement during the Yatala conversation that he did not have sexual intercourse
with her. That left open the possibility that he had lied during one of those
conversations.
202 The prosecutor submitted to the jury that the Warrnambool conversation was
referable to Mrs Poll but contended that his statement that he had engaged in sexual
activity with her was an ‘embellishment’. The prosecution did not contend at trial,
or on appeal, that the purported ‘embellishment’ evinced a consciousness of guilt,
nor was it submitted by the prosecutor that any such embellishment undermined
the appellant’s credibility or detracted from his denials.
203 Defence counsel submitted to the jury that, the appellant did not lie; in the
Warrnambool conversation he spoke of an affair with an unnamed woman (not
Mrs Poll) and in the Yatala conversation he denied having had a sexual relationship
with Mrs Poll. Thus, there was no inconsistency between the conversations and no
basis for the jury to find the appellant had told a lie.
204 It was common ground between the parties that for the jury to be satisfied
that the appellant had lied, they would first need to accept that the Warrnambool
conversation related to Mrs Poll. The trial Judge directed the jury in those terms.
The appellant contends, however, that the trial Judge was required to go further
and instruct the jury that they must first be satisfied beyond reasonable doubt that
the appellant was referring to Mrs Poll before they could use that as evidence of a
lie.
205 For the reasons which follow, we are satisfied that the jury were not required
to be satisfied that the appellant was referring to Mrs Poll in the Warrnambool
conversation to a standard of proof beyond reasonable doubt before they could use
the evidence to find that he had lied. It is true that if the jury were not satisfied
that the Warrnambool conversation was referable to Mrs Poll, it could not be used
as a basis to find the appellant had lied, or as part of the prosecution case at all.
The jury were directed in those terms. Whilst the jury would need to engage in
sequential reasoning to find the appellant had lied, it does not follow that the
Warrnambool conversation was an indispensable intermediate link in the chain of
reasoning towards an inference of guilt such that it needed to be proven beyond
reasonable doubt. The prosecution case did not rest on proof of the appellant’s
claimed connection with Mrs Poll made during the Warrnambool conversation,
nor on any purported lie told by the appellant. The appellant’s assertions in the
Warrnambool conversation were but one piece of circumstantial evidence
concerning a connection between the appellant and Mrs Poll in proof of the identity
of the offender as the appellant. It was not an indispensable link in proof of the
offence of murder. There was no requirement for the trial Judge to instruct the jury
in the terms contended by the appellant.

[2023] SASCA 80 The Court
51
Ground 3.3 – the lies direction was inadequate
206 As to the third limb of Ground 3, senior counsel for the appellant in her
written submissions contended that the trial Judge’s directions on lies were 'overly
general', namely that it was for the jury to determine the significance of any lies in
relation to the credit of the appellant and the issues in the case. It was submitted
that his Honour's 'generalised' directions, which were not linked to the facts in
issue, gave rise to a risk of misuse by the jury.
207 Evidence which suggests a consciousness of guilt by an accused is admissible
as an implied admission against interest. If the prosecution relies upon such
evidence in a criminal trial, it is open to the accused to offer some explanation,
consistent with innocence, which may nullify its force. Various categories of
evidence suggesting a consciousness of guilt have been recognised in the case
law.30
208 In Edwards v The Queen,31 (‘Edwards’) the High Court distinguished
between lies told by an accused which affect only his or her credit and lies told by
an accused that are evidence because they constitute implied admissions against
interest. Lies will constitute implied admissions if they are told out of a
consciousness of guilt; that is, the accused told the lies because of a realisation of
guilt and a fear of the truth.
209 An Edwards direction is ordinarily essential if the Crown relies on a lie told
by the accused as evidence of his or her guilt. As Lord Devlin observed in
Broadhurst v The Queen,32 there is a natural tendency for a jury to think that, if an
accused is lying, it must be because he or she is guilty. The rationale for giving an
Edwards direction is the avoidance of a perceptible risk of a miscarriage of justice
if the jury were to misuse the lie so as to make a finding of guilt by impermissible
reasoning. There is no precise verbal formula for the direction. A trial judge
should tailor the direction to the circumstances of the case.
210 If an Edwards direction is required, the direction must ordinarily encompass
the following:33
(a) the lie must be precisely identified;
(b) the lie will not be evidence against the accused unless the lie was
deliberate;
(c) there are many reasons why people tell lies, apart from the realisation
of guilt;
30 See, for example, Cooper v The Queen (2012) 87 ALJR 32 at [86]-[87] per Heydon J.
31 (1993) 178 CLR 193.
32 [1964] AC 441 at 457 per Lord Devlin.
33 Edwards v The Queen (1993) 178 CLR 193 at 209-211 per Deane, Dawson and Gaudron JJ. See also
Osland v The Queen (1998) 197 CLR 316 at [42] per Gaudron & Gummow JJ.
-- 55 of 90 --
[2023] SASCA 80 The Court
52
(d) the lie cannot be used as evidence against the accused if the jury accepts
an explanation for the lie that is consistent with innocence;
(e) the lie will not be evidence against the accused unless the lie was told
out of a consciousness of guilt (that is, the accused knew that the truth
would implicate him or her in the offence) and the lie reveals
knowledge of the offence charged or some aspect of it; and
(f) the facts, events and circumstances relied upon by the Crown to indicate
that the lie constitutes an admission against interest must be precisely
identified.
211 An accused's post-offence incriminating conduct, including lies which the
prosecution alleges constitute implied admissions against interest, is circumstantial
evidence. A jury may accept and act upon evidence of the accused's post-offence
conduct, including lies, if the conduct constitutes an implied admission against
interest, without being satisfied beyond reasonable doubt that the evidence
establishes guilt (that is, without being satisfied that there is no other explanation
of the post-offence conduct which is reasonably open on the facts), unless the
post-offence conduct is the only evidence against the accused or is an
indispensable link in the chain of reasoning on which proof of guilt depends.34
212 An accused's post-offence incriminating conduct, including lies which the
prosecution alleges constitute implied admissions against interest, must not be
considered on a piecemeal basis, but must be evaluated as part of the totality of the
evidence.35
213 In Zoneff, the appellant was convicted, after a trial in which he was
self-represented, of six of the seven charged offences. He gave evidence at the
trial in which he denied the alleged offending. The prosecutor elected not to
address the jury. During cross-examination, the prosecutor asked a number of
questions in response to which the appellant admitted having lied in his dealings
with the complainants. The prosecutor also put to the appellant on a number of
occasions that he was telling lies. The prosecutor did not present the case on the
basis that, if the jury found that the appellant had told lies, the prosecution relied
on the lies as evidence of the appellant's guilt. The trial Judge directed the jury
about the significance of any lies which the jury found the appellant had told. The
Judge referred to the possibility that any lies the appellant had told may indicate a
consciousness of guilt. The Judge reminded the jury, however, that there were
many reasons why people lie and some of those reasons were not consistent with
guilt.
214 A majority of the High Court in Zoneff allowed the appeal, set aside the

Judge, having raised the topic of lies, largely left the topic 'up in the air'.36 There
was 'a serious danger that the jury might, themselves, seek to identify relevant lies
and then draw adverse conclusions from them in an uninformed and impermissible
manner'.37 The Judge's directions 'fell far short of those mandated' in Edwards.38
215 Chief Justice Gleeson, Gaudron, Gummow and Callinan JJ observed that for
the trial Judge to raise, on his own initiative and in the manner he did, 'the
possibility of a consciousness of guilt without any identification of relevant
answers, and without any further explanation, was to invite the jury to infer that
the alleged lies might be indicative of a consciousness of guilt', a position that was
not advanced by the prosecution.39
216 Their Honours said that the case (Zoneff) was an unusual one.40 The
prosecutor did not at the trial (or on appeal) suggest that any answer given by the
appellant in cross-examination was a lie told out of a consciousness of guilt.41
Consequently, their Honours were of the opinion that it was unnecessary and
undesirable that an Edwards direction be given in the circumstances of the case.42
217 Their Honours noted that the trial Judge was apparently concerned that,
having regard to some of the prosecutor's cross-examination of the appellant, there
was a real risk that the jury might use impermissible reasoning in relation to the
alleged lies.43 Their Honours then said:44
A direction which might have appropriately been given and which would have allayed any
concerns which the trial Judge may have had, in this unusual case, in which the issues may
not have been defined as they might have been had the prosecutor made a speech to the
jury, is one in these terms:
“You have heard a lot of questions, which attribute lies to the accused. You will
make up your own mind about whether he was telling lies and if he was, whether he
was doing so deliberately. It is for you to decide what significance those suggested
lies have in relation to the issues in the case but I give you this warning: do not follow
a process of reasoning to the effect that just because a person is shown to have told
a lie about something, that is evidence of guilt.”
A direction in such terms may well be adaptable to other cases in which there is a risk of a
misunderstanding about the significance of possible lies even though the prosecution has

not suggested that the accused told certain lies because he or she knew the truth would
implicate him or her in the commission of the offence.
218 It is of significance, in our opinion, that the terms of the direction set out by
their Honours in Zoneff was said to be a direction which might have 'appropriately
been given' in the 'unusual' circumstances of Zoneff and that the terms of the
direction 'may well be adaptable to other cases' in which there is a risk of a
misunderstanding about the significance of possible lies.45
219 In Osland v The Queen,46 (‘Osland’) the appellant and her son were tried
jointly with the murder of a man who was the appellant's husband and her son's
stepfather. The appellant and her son gave evidence. Neither disputed that they
had killed the deceased. Each of them relied on provocation and self-defence.
Both gave evidence that the deceased had behaved violently over many years and
that the violence had increased in the days before his death. The son adduced
evidence that, on the evening of the killing, the deceased had threatened to kill
him. The appellant adduced expert evidence of 'battered woman syndrome'. The
jury convicted the appellant of murder but was unable to reach a verdict in respect
of the son. Later, the son was retried and acquitted. In the High Court, a majority
(McHugh, Kirby and Callinan JJ; Gaudron and Gummow JJ dissenting) held that
the appellant's conviction was not inconsistent with the jury's failure to reach a
verdict in respect of the son. All members of the High Court agreed that the
appellant's appeal must be dismissed, except for the issue of inconsistency.
220 The appellant in Osland engaged in deceptive conduct to conceal the
deceased's death and give the impression that he had merely disappeared. The trial
Judge did not direct the jury that it might treat this conduct as evidence of the
appellant's guilt. Consequently, an Edwards direction was not given.
221 Justices Gaudron and Gummow were of the view that, although the jury was
not directed that the appellant's lies might be evidence of her consciousness of
guilt, 'there was a real risk that [the jury] might reason that, because she lied about
her husband's disappearance, she must have known he had been the victim of
premeditated murder'.47 Their Honours observed that the prosecution had
'suggested as much' by inviting the jury to find that the appellant's conduct was not
that 'of a person who had killed somebody with lawful justification or excuse'.48
222 Justices Gaudron and Gummow then said:49
Where, as here, there is a risk that a jury might treat lies as evidence of guilt, the preferable
course is for the trial judge to ascertain precisely what use the prosecution contends may
be made of the evidence in question. And if the evidence is to be left to the jury as evidence
of guilt, it should be instructed as required by Edwards v The Queen. If not, it should be

instructed that the evidence is relevant only to the credit of the accused. Only by adopting
that course can a trial judge guard against “a perceptible risk of injustice”.

223 In Dhanhoa v The Queen,50 (‘Dhanhoa’) the appellant was convicted after
trial of robbery in company with wounding, and kidnapping. On 27 September
1999, police interviewed the appellant in connection with the alleged offending.
Later, the appellant was charged. The trial began on 1 May 2000. The appellant
gave evidence at the trial. In the prosecutor's closing address, the prosecutor
referred to differences between what the appellant had told police on 27 September
1999 and what the appellant had said in evidence at the trial. The prosecutor did
not submit that what the appellant had said to police constituted lies indicating a
consciousness of guilt. The trial Judge did not raise that possibility in his summing
up. An Edwards direction was not sought or given.
224 A majority of the High Court in Dhanhoa dismissed the appeal.
225 Chief Justice Gleeson and Hayne J said:51
It is not necessary for a trial judge to give a direction, either of the kind referred to in
Edwards, or of the kind referred to in Zoneff, every time it is suggested, in cross-
examination or argument, that something that an accused person has said, either in court or
out of court, is untrue or otherwise reflects adversely on his or her reliability. Where the
prosecution does not contend that a lie is evidence of guilt, then, unless the judge
apprehends that there is a real danger that the jury may apply such a process of reasoning,
as a general rule it is unnecessary and inappropriate to give an Edwards direction. Zoneff
was said to be an unusual case, and the direction there proposed was said to be appropriate
where there is a risk of misunderstanding about the significance of possible lies. The
present was not such a case.
(citations omitted)
226 Justices McHugh and Gummow noted that, in his summing up, the trial Judge
directed the jury:52
“The Crown says that … you will remember what the accused said when he was spoken to
by the police officers at the time of his arrest and compare that to what he says to you now
remembering that he received the police brief in this matter in February.”
227 Their Honours also noted that the judge then said:53
All those matters are part of the Crown case and it is for you to determine whether there is
any relevance in that or whether there is not. It is entirely a matter for you.
228 Justices McHugh and Gummow were of the opinion that, but for that last
statement, 'there would be no arguable ground for upholding the contention that

-- 59 of 90 --
[2023] SASCA 80 The Court
56
the trial Judge should have directed the jury concerning the effect of lies if they
thought Dhanhoa had lied to the police'.54 Their Honours elaborated:55
If the jury found that Dhanhoa had lied to the police, they were entitled to infer that his
evidence lacked credibility. But we think that, if the Crown had asked for a direction, the
jury were also entitled to conclude that he had lied because he knew that the victim had
been assaulted, robbed and detained. That is to say, the jury were entitled to think that he
had lied because he was conscious that he was guilty of participating in the crimes and
could give no innocent explanation for his presence at the flat if he had admitted that he
was there. But the Crown made no attempt to run a case of consciousness of guilt. At no
stage of Dhanhoa's cross-examination did the prosecutor expressly suggest to him that he
had lied to the police because he had a consciousness of guilt. And because that was so, the
trial Judge did not direct the jury that, if they thought he had lied to the police, they could
use the lie as evidencing a consciousness of guilt on his part. But the trial Judge did direct
the jury that various matters — one of which was the difference between what the accused
told the jury and what he told the police — was “part of the Crown case and it is for you to
determine whether there is any relevance in that”.
It is possible, therefore, that the jury may have reasoned that the accused was guilty because
he had lied to the police. It is not necessary for a trial judge to give a direction concerning
lies as evidence of guilt whenever a prosecutor suggests directly or indirectly that an
accused's out-of-court statement is a lie. But in this case it would have been better if the
trial Judge, having given the direction that he did, had instructed the jury as to how they
were to use any lie told by the accused. Given the way that the Crown conducted its case,
it would have been better if the trial Judge had directed the jury that the accused's lies, if
they found he had lied, only affected his credibility.
(citations omitted)
229 Their Honours said that it was insufficient to establish a miscarriage of justice
merely to show that 'it would have been better if the trial Judge had given an
appropriate direction concerning the effect of lies or that there is a possibility that
the jury may have reasoned that the accused was guilty because he had lied to the
police'.56 It was necessary, to succeed in the appeal, that the appellant establish
that 'it is a reasonable possibility' that the trial Judge's failure to direct the jury
'may have affected the verdict'.57 Their Honours referred to Simic v The Queen58
and then said:59
Given the way that the prosecution conducted its case, we think that there is only a very
slender possibility that the jury would have considered that his statement to the police
indicated a consciousness of guilt. The jury would have done so only if, despite the way
the Crown conducted its case, the jurors decided to add consciousness of guilt to the process
of reasoning on which the Crown relied. It is true that the trial Judge told the jury that it
was a matter for them to determine whether there was any relevance in the claimed
inconsistency. But that was not an invitation to use consciousness of guilt reasoning
although it is, of course, possible the jury decided to use it. But even if the jury decided to

57
examine the accused's answers to the police as indicating a consciousness of guilt, to
succeed in this appeal Dhanhoa must show a reasonable possibility that they convicted him
because they took his statements as evidencing that consciousness.
230 Justices McHugh and Gummow concluded that there was no reasonable
possibility that the verdict of guilty would have been different if the trial Judge had
given a direction concerning lies.60 Their Honours added that an Edwards direction,
if given, 'might not only have emphasised the issue but made it difficult for the
jury to disregard consciousness of guilt as an issue'.61
231 In the present case, the out-of-court statements allegedly made by the
appellant to M in the Warrnambool conversation and the Yatala conversation were
admissible at the trial because her evidence of the conversations included alleged
statements by the appellant which, on the prosecution's case, were admissions
against interest. M's evidence as to the appellant's alleged out-of-court statements
became evidence of the facts in issue whether the alleged statements by the
appellant were inculpatory or exculpatory.62
232 In addition to the possible lies identified by the trial Judge (that is, the
appellant’s claim during the Warrnambool conversation that he had engaged in
sexual activity with Mrs Poll, or alternatively, his denial in the Yatala conversation
of having had a sexual relationship with Mrs Poll), we consider that there was also
a basis in M's evidence for concluding that the appellant may have told a lie during
the Warrnambool conversation when he said that the married woman's husband
had found out about the affair and knifed her.
233 In particular, if the jury found that the appellant's statement in the
Warrnambool conversation that he had previously had an affair with a married
woman was true and if the jury accepted the prosecution's contention that the
married woman was Mrs Poll and if the jury accepted (consistently with the
prosecution case and the appellant's case) that Mr Poll was not responsible for
Mrs Poll's death, then the appellant may have lied when he said in the
Warrnambool conversation that the married woman's husband found out about the
affair and knifed her.
234 As to the possible lies identified, the prosecution's position at the trial was as
follows:
(a) The prosecutor did not refer in her opening address to M's anticipated
evidence as to the Warrnambool conversation or the Yatala
conversation.

[2023] SASCA 80 The Court
58
(b) The prosecutor did not assert in her opening address that the appellant
had told or may have told any lie.
(c) The prosecutor adduced evidence from Mr Poll to the effect that, from
Mr Poll's perspective, his marriage to Mrs Poll was a 'happy one'.
(d) The prosecutor adduced evidence from Mrs Taylor to the effect that she
had observed the relationship between Mr and Mrs Poll, and they were
'happy' and 'got on well together'.
(e) The prosecutor said in her closing address that it was natural to think
that 'someone with a great deal of personal hatred for [Mrs Poll] must
have committed this crime'. However, the prosecutor added that she
did not 'pretend for a moment to suggest why Mrs Poll was killed or
why she was killed in the way she was', but the jury should not place
much weight on the fact that the appellant apparently had no motive to
kill her.
(f) The prosecutor submitted in her closing address that the weight of the
evidence revealed that Mrs Poll was happily married and there was an
absence of evidence of anyone having an obvious motive to harm her.
(g) The prosecutor submitted in her closing address that if the jury accepted
M's evidence concerning the Warrnambool conversation and if the jury
found that Mrs Poll was the married woman to whom the appellant
referred, then it would be open to the jury to conclude that the appellant
was claiming to have some connection with Mrs Poll, that the appellant
was speaking about the circumstances of Mrs Poll's killing and that the
appellant was showing an interest in Mrs Poll and her murder.
(h) The prosecutor said in her closing address that the prosecution did not
rely upon M's evidence as proof of an affair between the appellant and
Mrs Poll. The prosecutor explained that what was significant, if the
jury accepted M's evidence, was that in the middle of 2019, some
26 years after Mrs Poll was killed, the appellant was talking about a
married woman who worked in a shop, who was knifed to death and
'the culprit [got] away with it'.63
(i) The prosecutor submitted in her closing address that, even if 'the
claimed affair is a complete embellishment', the appellant was claiming
to have an association with a married woman and there were features of
the conversation that could lead the jury to draw the inference that the
appellant was speaking about Mrs Poll. Those features were that the
appellant was talking about an older woman; the woman was married;
she worked in a shop; he used to go into the shop; the woman asked him
63 Emphasis added.
-- 62 of 90 --
[2023] SASCA 80 The Court
59
to come back one night; the woman was knifed; and the police 'never
got the person responsible for it'.64
(j) According to the prosecutor in her closing address, 'the key features are
so aligned that [the appellant] must have been talking [in the
Warrnambool conversation] on the topic of [Mrs Poll] and the
circumstances of her killing'. The prosecutor suggested that 'the details
of a married woman who worked in a shop being knifed to death, bring
this matter that [the appellant] was talking about within a fairly narrow
compass' and when the appellant 'talks about it being a shop he used to
go into, the compass is even narrower'.
(k) The prosecutor submitted in her closing address that if the jury accepted
that the appellant told M, 'I knew this woman. She was knifed and I
knew her', then the jury '[could] look at the DNA results in that light'.
The prosecutor elaborated that it would be 'a coincidence beyond
comprehension that crime scene and/or laboratory error in relation to
samples implicating [the appellant] took place in respect of a crime
which he happens to speak about with a new girlfriend in another State
all those years later'.
(l) The prosecutor made only a brief passing reference in her closing
address to the Yatala conversation.
(m) The prosecutor did not say to the jury in her closing address (or at any
other stage of the trial) that the appellant had lied in the Warrnambool
conversation or the Yatala conversation.
235 As to the possible lies identified, the appellant's position at trial was as
follows:
(a) Defence counsel did not refer in her opening statement to the
Warrnambool conversation or the Yatala conversation.
(b) Defence counsel did not refer in her opening statement to any alleged
lies the appellant had told or may have told.
(c) Defence counsel adduced evidence from Mr Poll to the effect that he
had a 'good marriage' with Mrs Poll, that he was not aware of any affair
by either of them and that he and Mrs Poll had not had any 'major
falling-out'.
(d) Defence counsel put to M in cross-examination that the appellant did
not mention in the Warrnambool conversation anything about a woman
being 'knifed to death or knifed', a proposition which M rejected.
64 Emphasis added.
-- 63 of 90 --
[2023] SASCA 80 The Court
60
(e) Defence counsel did not cross-examine Mrs Taylor.
(f) Defence counsel adduced evidence from Detective Huppatz that there
was no evidence that he could find 'that there was ever any suggestion
that [Mrs Poll] was having an affair or being unfaithful to her husband'.
(g) Defence counsel submitted in her closing address, in essence, that the
effect of the evidence of Mr Poll, Mrs Taylor and Detective Huppatz
was that Mrs Poll was happy in her marriage and there was no basis for
thinking that she may have had an affair. Defence counsel suggested,
in essence, that consequently there was no basis for supposing that in
the Warrnambool conversation the appellant was talking about an affair
with Mrs Poll. Defence counsel referred to the evidence of Ms Young
that she was still in a relationship with the appellant at least in
November 1993 and submitted that, having regard to the date on which
Mrs Poll was killed and the reference in the Warrnambool conversation
to the married woman having been killed 'after Miffy [that is, after
Ms Young]', the appellant was not talking about an affair with Mrs Poll.
(h) On the appellant's case, as put by defence counsel, the married woman
to whom the appellant referred in the Warrnambool conversation was
not Mrs Poll but another woman.
(i) Defence counsel noted M's evidence that in the Yatala conversation the
appellant in effect had denied having an affair with Mrs Poll. Defence
counsel submitted that the appellant's reaction to M's mention of the
Warrnambool conversation was consistent, in essence, with the
appellant asserting that what M had said about the Warrnambool
conversation, when she met with the appellant at Yatala Prison, was not
correct.
(j) Defence counsel submitted in her closing address, in essence, that the
jury should not accept that M's evidence as to the Warrnambool
conversation was correct because there was no evidence of an affair by
Mrs Poll.
(k) Defence counsel did not rely upon the appellant's assertion in the
Warrnambool conversation that the husband of the married woman had
knifed her.
(l) Defence counsel did not refer in her closing address to any alleged lies
the appellant had told or may have told.
236 As to the possible lies identified, the trial Judge directed the jury in his
summing up as follows:
(a) The jury could only 'use the Warrnambool conversation against
[the appellant]' if the jury accepted that the Warrnambool conversation
-- 64 of 90 --
[2023] SASCA 80 The Court
61
occurred as M recounted in her evidence. If the jury made that finding
then it was open to the jury to infer, based on M's evidence as to the
Warrnambool conversation together with other circumstantial evidence
adduced at the trial, that Mrs Poll was the married woman to whom the
appellant was referring.
(b) If the jury inferred, as permitted by his Honour's direction, that Mrs Poll
was the married woman to whom the appellant was referring in the
Warrnambool conversation, then it was open to the jury to infer that the
appellant had 'some sort of connection with, or interest in, Mrs Poll in
some way' and 'some interest in her death in some way'. However,
his Honour said that it did not necessarily follow that what the appellant
said about having sexual intercourse with Mrs Poll was true. That
aspect of what the appellant said 'may be untrue'. But, if that aspect was
untrue, it was still open to the jury to infer that the appellant had 'an
interest in [Mrs Poll] and the fact that [the appellant] was prepared to
claim that he had had [sexual] intercourse with her may display the
holding of such an interest, talking about a person sexually'.
237 His Honour directed the jury that if they were to conclude that the appellant
lied in the Warrnambool conversation or the Yatala conversation, then 'it was for
[the jury] to say what conclusion you come to concerning such a lie'.
238 The trial Judge then gave the jury a direction which mirrored the direction
formulated by Gleeson CJ, Gaudron, Gummow and Callinan JJ in Zoneff as a
direction which their Honours said:65
… might have appropriately been given [in Zoneff] and which would have allayed any
concerns which the trial Judge may have had, in this unusual case, in which the issues may
not have been defined as they might have been had the prosecutor made a speech to the
jury.
239 His Honour directed the jury that even if the prosecution proved the blood
and DNA deposition evidence beyond reasonable doubt, it would be necessary for
the jury to consider the evidence of the likelihood ratios in combination with other
prosecution evidence which the jury decided was established 'when ultimately
considering whether the prosecution has proven [the appellant's] guilt beyond
reasonable doubt'.
240 As we have mentioned, Ground 3.3 alleges that the trial Judge's directions
were flawed insofar as they constituted a lies direction. His Honour's directions
on lies must be considered by taking the directions (and the summing up) as a
whole. They must be considered from the perspective of a jury listening to those
directions (and the summing up) as a whole and how the jury might understand
65 Zoneff v The Queen (2000) 200 CLR 234 at [23] per Gleeson CJ, Gaudron, Gummow and Callinan JJ.
-- 65 of 90 --
[2023] SASCA 80 The Court
62
them, and not upon a subtle examination of the transcript or by giving undue
prominence to any individual parts.66
241 We turn to consider whether the trial Judge was required to direct the jury
that if they were to conclude that the appellant lied during the Warrnambool
conversation, then that conclusion was relevant only to the appellant's credit and
the jury could not treat that conclusion as evidence of the appellant's guilt.
242 That question arises in respect of the possible lies in the Warrnambool
conversation that first, the appellant had a sexual relationship with Mrs Poll and
second, her husband found out about the affair and knifed her.
243 The risk of the jury identifying and misusing those possible lies must be
evaluated in the context of the following:
(a) The prosecution case at the trial was that on 29 April 1993 the appellant
killed Mrs Poll by inflicting multiple stab wounds with a knife and that
the appellant did not become a suspect in the murder investigation until
about September 2019 (that is, after the occurrence of the Warrnambool
conversation in about early July 2019).
(b) The prosecutor did not say to the jury at any stage of the trial that the
appellant had lied during the Warrnambool conversation.
(c) The prosecutor did, however, submit to the jury, in essence, that
M's evidence as to the content of the Warrnambool conversation
(including M's evidence that the appellant said the married woman was
frightened that her husband would find out about their affair and that
the husband 'did find out and [the husband] knifed her and they never
got him for it') was true and correct.
(d) The prosecutor submitted to the jury, in essence, that if the jury found
that M's evidence as to the content of the Warrnambool conversation
was true and correct, then it would be open to the jury to conclude, and
the jury should conclude, that the appellant was claiming to have some
connection with Mrs Poll, that the appellant was speaking about the
circumstances of Mrs Poll's killing and that the appellant was showing
an interest in Mrs Poll and her murder.
(e) The prosecutor submitted to the jury, in essence, that there was no
evidence that at any time Mrs Poll had been engaged in an extramarital
affair. The prosecutor then submitted, in essence, that even if the jury
found that Mrs Poll was not having an affair with the appellant or
anyone else, the jury should nevertheless conclude that during the
Warrnambool conversation the appellant was claiming to have had an
66 See R v Dookheea (2017) 262 CLR 402 at [37] per Kiefel CJ, Bell, Gageler, Keane, Nettle &
Edelman JJ.
-- 66 of 90 --
[2023] SASCA 80 The Court
63
association with Mrs Poll and '[the appellant] must have been talking
on the topic of [Mrs Poll] and the circumstances of her killing'.
(f) The prosecution's case at the trial was that Mr Poll was not responsible
for Mrs Poll's death.
(g) It was therefore, at least implicitly, a material aspect of the prosecution
case at the trial that if the jury found that M's evidence as to the content
of the Warrnambool conversation was true and correct and if the jury
concluded that during the Warrnambool conversation the appellant was
claiming to have had an association with Mrs Poll and '[the appellant]
must have been talking on the topic of [Mrs Poll] and the circumstances
of her killing', then the appellant's assertions in the conversation that he
had sex with a married women and that '[the husband] knifed her and
they never got him for it' were untrue and incorrect.
(h) The prosecutor did not expressly confront the divergence between the
appellant's assertion (on M's evidence) that the husband of the married
woman had knifed her, on the one hand, and the prosecution case that
Mr Poll was not responsible for Mrs Poll's death, on the other, despite
the prosecutor submitting to the jury that (if the jury found that
M's evidence as to the content of the Warrnambool conversation was
true and correct) the appellant was claiming to have some connection
with Mrs Poll, the appellant was speaking about the circumstances of
Mrs Poll's killing and the appellant was showing an interest in Mrs Poll
and her murder.
(i) The prosecutor appears to have dealt with the divergence by saying that
what was significant about the Warrnambool conversation was not
whether the appellant had an affair with Mrs Poll, but that in the middle
of 2019, some 26 years after Mrs Poll was killed, the appellant was
talking about a married woman who worked in a shop, who was knifed
to death and 'the culprit got away with it'.67
(j) The prosecutor also appears to have dealt with the divergence, in the
course of enumerating the features of the Warrnambool conversation
that, on the Crown's case, should lead the jury to draw the inference that
the appellant was speaking about Mrs Poll, by saying that those features
included the appellant asserting that the police 'never got the person
responsible for it'.68
(k) The prosecutor submitted that, although there were points of difference
between what the appellant said in the Warrnambool conversation and
what was known about Mrs Poll's life, the appellant must have been
speaking about Mrs Poll and the circumstances of her killing and, if he
67 (emphasis added).
68 (emphasis added).
-- 67 of 90 --
[2023] SASCA 80 The Court
64
was speaking about those matters, then it was clear that the appellant
was claiming to have some connection to Mrs Poll. The prosecutor
elaborated that if the jury found that the appellant was speaking about
Mrs Poll and the circumstances of her killing, then the jury could
consider the DNA evidence in that light; in particular, what were the
chances of a 'crime scene and/or laboratory error in relation to samples
implicating [the appellant]' in respect of a crime about which the
appellant was speaking to a new girlfriend, in another State, 26 years
after the event.
(l) Defence counsel submitted, in essence, that the jury should not be
satisfied that the Warrnambool conversation related to Mrs Poll
because the appellant was talking about an affair with a married woman
and the evidence at the trial established that Mrs Poll had not engaged
in an extramarital affair. It was submitted, in essence, that either M had
'got things mixed up' or the appellant was not referring to Mrs Poll in
the conversation.
(m) The trial Judge directed the jury, in essence, that if the jury found that
M's evidence as to the content of the Warrnambool conversation was
true and correct, then the jury must not use the evidence of that
conversation:
(i) to find that what the appellant said in the conversation displayed
'some sort of knowledge that only the killer could have had'; or
(ii) to reason that the appellant was a person of bad character because
he was prepared to encourage adultery by a married woman.
(n) His Honour directed the jury, in essence, that if the jury found that
M's evidence as to the content of the Warrnambool conversation was
true and correct, then it would be open to the jury to draw an inference
that Mrs Poll was the married woman to whom the appellant was
referring and, if the jury drew that inference, it would be open to the
jury to draw a further inference that the appellant had 'some sort of
connection with, or interest in, Mrs Poll in some way or, indeed, some
interest in her death in some way', even if the jury were not satisfied
that the appellant was having an affair with Mrs Poll.
(o) The trial Judge directed the jury, in essence, that if the jury concluded
that the appellant told a lie during the Warrnambool conversation, then
'it was for [the jury] to say what conclusion you come to concerning
such a lie'. The jury should 'make up your own mind whether
[the appellant] told a lie and if he did whether he did so deliberately'. It
was for the jury 'to decide what significance a lie may have in relation
-- 68 of 90 --
[2023] SASCA 80 The Court
65
to the credibility of [the appellant] and the issues in the case'.69
His Honour then warned the jury not to follow 'a process of reasoning
to the effect that just because a person is shown to have told a lie about
something that is positive evidence of his guilt of the offence charged'.70
(p) His Honour directed the jury, in essence, that even if the prosecution
proved the blood and DNA deposition evidence beyond reasonable
doubt, it would be necessary for the jury to consider that evidence (in
particular the likelihood ratios) in combination with other prosecution
evidence which the jury accepted when considering the ultimate
question, namely whether the prosecution had proven the appellant's
guilt beyond reasonable doubt. So, on his Honour's directions, proof by
the prosecution of the blood and DNA evidence was a necessary but not
a sufficient basis for conviction of the appellant.
244 In our opinion, having regard to the trial record, the prosecution's case, the
appellant's case and the trial Judge's directions, it was open to the jury to find that:
(a) M's evidence as to the content of the Warrnambool conversation was
true and correct;
(b) during the Warrnambool conversation the appellant was speaking about
Mrs Poll and the circumstances of her killing;
(c) during the Warrnambool conversation the appellant was claiming to
have had an association with or a connection to Mrs Poll and he was
showing an interest in Mrs Poll and her murder; and
(d) Mr Poll was not responsible for Mrs Poll's death and consequently the
appellant's assertion in the Warrnambool conversation that
'[the husband] knifed her and they never got him for it' was untrue and
incorrect.
245 It is therefore necessary to consider whether, if the jury made those findings,
there was a real risk, having regard to the trial record, the prosecution's case, the
appellant's case and his Honour's directions, that:
(a) the jury may have reasoned that the appellant told a lie in implicating
Mr Poll as the person who had knifed Mrs Poll and that the appellant
told the lie to conceal that in fact he had knifed Mrs Poll; and
(b) the jury may have used that reasoning, in combination with other
evidence which the jury accepted including the prosecution blood and
69 Emphasis added.
70 Emphasis added.
-- 69 of 90 --
[2023] SASCA 80 The Court
66
DNA deposition evidence, in arriving at its ultimate conclusion that the
prosecution had proven the appellant's guilt beyond reasonable doubt.
246 It is also necessary to consider whether in relation to the possible lie
identified by the trial Judge, the jury may have found that the appellant was
speaking about Mrs Poll and the circumstances of her killing and that the
appellant’s statement that he had sex with a married women for several weeks (that
being Mrs Poll) constituted a deliberate lie; and used that lie as evidence of his
guilt.
247 In our opinion, any risk of the jury reasoning in the manner we have indicated
in relation to each of the possible lies was adequately guarded against by the trial
Judge's directions to the jury in the context of the trial record, the prosecution's
case and the appellant's case at the trial. Our reasons for that opinion are as
follows.
248 First, his Honour directed the jury that the jury must not use M's evidence as
to the content of the Warrnambool conversation to find that what the appellant said
in the conversation displayed 'some sort of knowledge that only the killer could
have had'. Second, his Honour directed the jury, in accordance with Zoneff not to
follow a process of reasoning to the effect that just because a person is shown to
have told a lie about something, that is positive evidence of his guilt of the offence
charged.71 Third, there is no reason to think that the jury would not have understood
and followed his Honour's directions.72 Fourth, the prosecutor did not say to the
jury at any stage of the trial that the appellant had lied during the Warrnambool
conversation. In particular, the prosecutor did not say to the jury at any stage that
the appellant had told or may have told the possible lies identified. Nor did the
prosecutor elevate the appellant’s purported ‘embellishment’ of having had a
sexual relationship with Mrs Poll to a deliberate lie. Fifth, despite it being the
prosecution's case that Mr Poll was not responsible for killing Mrs Poll, the
prosecutor merely referred in her closing address to the appellant having asserted
during the Warrnambool conversation that 'the culprit' got away with knifing the
married woman and the police never got 'the person' responsible for knifing her.
Sixth, defence counsel did not refer in her closing address to any alleged lies the
appellant had told or may have told. Indeed, the appellant's case, as put by defence
counsel, was that the appellant had not told any lies. Seventh, defence counsel,
who is an experienced criminal trial lawyer, did not request his Honour to give the
jury an additional direction or a redirection to the effect that if the jury found that
the appellant had told any lies in the Warrnambool conversation then the lies were
relevant only to his credit (and were not evidence of his guilt). Eighth, defence
counsel sought, in the absence of the jury, to clarify with his Honour the directions
that his Honour had given about lies. Defence counsel was content with the
explanation his Honour gave. It is apparent, therefore, that defence counsel, who

72 See Gilbert v The Queen (2000) 201 CLR 414 at [13] per Gleeson CJ & Gummow J, [31]-[32] per

Heydon, Crennan, Kiefel & Bell JJ.
-- 70 of 90 --
[2023] SASCA 80 The Court
67
was absorbed in the atmosphere of the trial, did not perceive that any redirection
or additional direction was necessary including a direction to the effect that if the
jury found that the appellant had told any lies in the Warrnambool conversation
then the lies were relevant only to his credit (and were not evidence of his guilt).
Ninth, in all the circumstances to which we have referred, had his Honour given
the jury a direction to the effect that if the jury found that the appellant had told
any lies in the Warrnambool conversation then the lies were relevant only to his
credit (and were not evidence of his guilt), the direction would have raised an issue
in relation to the Warrnambool conversation on which the prosecutor and defence
counsel were not joined. The direction would have had the effect of highlighting
issues in relation to the appellant's credibility and giving those issues some
prominence in the jury's deliberations to the prejudice of the appellant. It is more
likely than not that defence counsel's omission to request a direction to the effect
that we have described was the result of a deliberate forensic decision.
249 Consequently, we are satisfied that the trial Judge was not required to direct
the jury that if the jury were to conclude that the appellant lied during the
Warrnambool conversation, then that conclusion was relevant only to the
appellant's credit and the jury could not treat that conclusion as evidence of the
appellant's guilt.
250 In any event, we are not satisfied that it is reasonably possible that
his Honour's failure to give a direction to the effect that we have described may
have affected the jury's verdict. None of the identified lies, if found proven in this
case, could have had any significant impact on the appellant’s credibility in
circumstances where the appellant did not participate in a police interview, nor
give evidence. The appellant’s account was found in his largely bland denials
during the recorded telephone calls to his family.
251 The appellant also submitted that the trial Judge did not direct the jury with
adequate specificity that the evidence of the appellant’s lies was relevant to the
jury’s assessment of the appellant’s denials in the recorded telephone
conversations. In circumstances where there was no other evidence of the
appellant’s denials or account, it would have been obvious to the jury that the trial
Judge’s directions related to the appellant’s denials in the recorded telephone
conversations.
252 We are not satisfied that the trial Judge’s directions as to lies resulted in a
miscarriage of justice.
253 We grant permission to appeal on Grounds 3.2, 3.3 and 3A but dismiss both
Grounds 3 and 3A.
Grounds 4 and 4A – Failing to put the defence case and unbalanced summing
up
254 The appellant complains that the trial Judge erred in his directions as to the
burden and standard of proof, and in failing to adequately and fairly present the
-- 71 of 90 --
[2023] SASCA 80 The Court
68
defence case (Ground 4). This ground of appeal has two limbs: first, that the trial
Judge erred in failing to adequately direct the jury that the prosecution must
exclude the reasonable possibility that the accused did not kill Mrs Poll; and
second, that the trial Judge erred in failing to adequately put the defence case as to
the forensic evidence and M’s evidence. The appellant also contends that the trial
Judge interspersed his presentation of the defence address with ‘rebuttal
comments’ and the trial miscarried as a result of an unbalanced summing up
(Ground 4A).
255 In analysing the force of those complaints, it is necessary to say something
further about each respective parties’ case at trial.
256 As discussed earlier, the central issue in dispute was whether the prosecution
had proven the identity of the offender as the appellant. There was no contest as
to the remaining legal elements of murder. In relation to the primary evidence
implicating the appellant, that being the blood and DNA deposition evidence, the
trial Judge directed the jury that the prosecution relied on six propositions in
relation to that evidence. First, the offender cut himself during the attack on
Mrs Poll. Second, there were 12 samples taken from the apparent blood stains
deposited by the offender. Third, those 12 samples were properly collected by
police and properly submitted for forensic testing. Fourth, those samples were
properly preserved and analysed, and the results correctly reported. Fifth, all 12
samples had at least one contributor that was male. Sixth, of the 12 samples there
were three single DNA profiles which identified a single contributor, and each had
a statistical weighting of over 100 billion in favour of the proposition that the
appellant was the contributor when compared with the hypothesis that it was from
an unknown male contributor. Thus, as outlined earlier, the blood and DNA
deposition evidence was described as a critical connection between the appellant
and the crime scene and an indispensable, intermediate link in proof of the offence
which needed to be established beyond reasonable doubt.
257 At trial, and as set out earlier, defence counsel’s submissions in relation to
the DNA evidence were two-fold. First, the evidence did not establish a chain of
evidence in relation to the collection, storage and examination of items undertaken
in 1993, and again, in 2019. It was submitted that various errors, missing items,
and an incomplete record of the history of those items were apparent in the
documentation now available. Moreover, witnesses made mistakes at the time of
analysis, and at the time of giving evidence, which undermined the chain of
evidence. Second, there were anomalies identified in the records which
undermined any confidence that proper procedures had been followed. It was also
contended that protocols in place in 1993, requiring protective clothing and
footwear protectors to be worn by crime scene examiners for the purpose of
avoiding contamination and mistakes, were not adequately followed as shown by
video footage recorded at that time.
258 In addition to contesting the DNA evidence, defence counsel also relied upon
a body of evidence called as part of the prosecution case which, it was submitted,
-- 72 of 90 --
[2023] SASCA 80 The Court
69
raised a reasonable possibility that the appellant was not the offender. That
included the following evidence:
• A qualified fingerprint expert, Senior Constable Graeme Bubner,
testified that several fingerprints were located throughout the
newsagency, and on Mrs Poll’s handbag, which were suitable for
identification; none of the fingerprints matched those of the appellant.
• A witness described seeing a male inside the newsagency at 8:55pm
who did not fit the appearance of the appellant.
• Another witness observed a male in the vicinity of the newsagency
between around 8:50pm and 8:55pm who did not fit the appearance of
the appellant.
• As to the evidence of Ms Parsons that she observed a male in the
vicinity of the newsagency with dark facial hair, the appellant’s mother,
Ms Richardson, gave evidence that he was always clean shaven.
• The appellant worked at a service station in 1993. Due to the passage
of time, his employment records were unable to be obtained by police,
depriving him of the ability to establish an alibi.
• The appellant repeatedly denied being involved in the murder during
recorded telephone calls from October 2019 to May 2020.
• As to the evidence that the offender may have sustained a cut or
free-bleeding injury during the attack on Mrs Poll, Ms Richardson, and
Ms Young gave evidence that they did not observe any cut or injury to
the appellant’s hand in April 1993.
• Fingernail cuttings taken from Mrs Poll were analysed for the presence
of DNA; the appellant was not a contributor to the DNA profile
extracted from those cuttings. Dr James gave evidence that the DNA
of an assailant was often found under fingernails due to defensive
scratching.
• The evidence of Dr Sara Jones in relation to the size of shoe worn by
the offender implicated 40 per cent of the male population and the type
of shoe the subject of the examination was proved to have not been
worn by the appellant.
• As to the evidence of M regarding the Warrnambool conversation, and
to the extent that the jury were satisfied that the appellant was referring
to Mrs Poll (as discussed in relation to Ground 3), such assertions
included an exculpatory statement, namely a denial that he was the
offender and an assertion that Mrs Poll’s husband stabbed her because
-- 73 of 90 --
[2023] SASCA 80 The Court
70
he learnt that they were having an affair. Defence counsel challenged
M’s account, and that it was referable to Mrs Poll, on the basis that: (i)
she wrongly concluded that the subject matter was about Mrs Poll
because of his subsequent arrest for the offence; (ii) there was no other
material or evidence that suggested Mrs Poll was having an affair with
the appellant, or anyone; and (iii) according to M, the appellant spoke
of the affair having occurred at a time after he ended his relationship
with Ms Young, which placed it at a time after the murder.
• Beyond M’s evidence, there was no other evidence to suggest that the
appellant was having an affair with Mrs Poll.
• There was no evidence that the appellant had a motive to commit the
offence.
259 The appellant complains that the trial Judge did not adequately put the full
breadth of the defence case. In relation to the first limb of this contention, that the
trial Judge erred in his directions as to the burden and standard of proof, the issue
arose at trial in the following way. At the outset of his summing up, the trial Judge
gave directions as to the presumption of innocence which he said could only be
displaced by the prosecution proving beyond reasonable doubt every element of
the charge. The trial Judge also informed the jury that the appellant had no burden
of proof, including as to any defence put forward by the appellant, and that
suspicion of having committed the offence, or probable guilt, would not suffice.
His Honour reiterated that the burden remained with the prosecution to establish
guilt to the highest standard of proof beyond reasonable doubt.
260 The trial Judge then gave the impugned direction:
Ladies and gentlemen, if you think at the end of the day that it is a reasonable possibility
that someone other than the accused killed Mrs Poll, then of course you should acquit the
accused because the charge will not have been proven beyond reasonable doubt.
261 As discussed in relation to Ground 3, this direction had the effect of bringing
to the attention of the jury the appellant’s purported exculpatory statement in the
Warrnambool conversation that Mrs Poll’s husband had killed her.
262 During a break in the summing up, defence counsel sought a re-direction to
the effect that the jury must acquit if they found it to be a reasonable possibility
that the appellant did not kill Mrs Poll. Defence counsel submitted to the trial
Judge that the impugned direction may leave the jury with the impression that the
accused had to establish that there was a reasonable possibility someone else killed
Mrs Poll. The trial Judge ultimately did not re-direct on the topic. The appellant
submits to this Court that the impugned direction resulted in a miscarriage of
justice.
263 For the respondent, it is submitted that the impugned direction must be seen
in the context of the issues at trial, that being whether the prosecution had proved
-- 74 of 90 --
[2023] SASCA 80 The Court
71
that the appellant was the offender (that is, the identity of the offender); and
emphasised that there was no dispute that someone had murdered Mrs Poll. The
respondent submits that, in the circumstances of this case, a reference to the
prosecution being required to exclude as a reasonable possibility that Mrs Poll was
killed by someone other than the appellant was the logical equivalent of instructing
the jury that they must exclude as a reasonable possibility that the appellant did
not kill her; the direction was referring to one and the same thing.
264 In considering this complaint, the summing up must be read as a whole. At
the outset, the trial Judge outlined the standard and burden of proof in orthodox
terms. His Honour reiterated those matters when discussing the elements of the
offence of murder and when instructing the jury as to circumstantial evidence.
Bearing in mind that the only issue in dispute at trial was the identity of the
offender, we are satisfied that the jury would have well understood that the
prosecution were required to establish beyond reasonable doubt that the accused
killed Mrs Poll, including the exclusion as a reasonable possibility that someone
other than the accused killed her, or that the accused did not kill her (being, in
effect, the same reasonable possibility). The trial Judge did not, in the impugned
direction, or at any stage during his summing up, suggest that the jury would have
to identify an alternate killer in order to be left with a reasonable doubt that the
accused committed the offence.
265 As to the second limb of this ground of appeal, and the contention that the
trial Judge failed to adequately or fairly put the defence case as to the forensic
evidence and M’s evidence, and that his Honour interspersed his summary of the
defence address with rebuttal comments, there is considerable overlap between
these contentions and the complaint that the summing up was unbalanced. They
are, in effect, one complaint as to the unbalanced and unfair nature of the summing
up. In support of this contention, the appellant relied on the trial Judge’s ‘rebuttal’
of various parts of defence counsel’s submissions in her closing address.
266 Defence counsel relied on internal emails within the FSSA concerning a
‘fridge audit’ of samples seized from the crime scene (Exhibit D13) and the testing
of those samples (Exhibit D15) to demonstrate uncertainty as to the chain of
evidence. The trial Judge summarised defence counsel’s submissions on that
topic. However, the appellant submits that the trial Judge went on and diluted the
force of those submissions when he emphasised that the emails were internal
documents and formed only a small part of a voluminous file. His Honour said:
It is fair to mention the general dates that we are talking about here and that, of course,
these emails are not long after the accused was arrested on this charge and, accordingly,
people at forensic science had to, as it were, gird themselves to start all over again in
relation to this matter. So, if you look at the email of Dr Taylor D15 it is an introductory
sort of a thing … and then basically making introductory requests and inquiries as you
might, if you have suddenly got a big job ahead of you.
But, ladies and gentleman, these two items are internal emails not designed to be formal
documents. I will just say that. They are what they are. You place what weight you consider
-- 75 of 90 --
[2023] SASCA 80 The Court
72
but remember that there are a great number of records from forensic science and I referred
to those quantities a bit earlier today and one cannot expect a complete, an entire, recitation
of a situation on any particular one document or email.
In any event, defence counsel went on to refer to some cross-examination of Mr Taylor
concerning taking cuttings from a [forensic recovery evidence device] generally and then
went on to make this submission:
“With D13 in mind as the only window we have on how these items have been stored
and kept in a centre you can’t exclude, I suggest, the risk that there has been a
contamination which has affected those results.”
Ladies and gentleman, the records are voluminous; it will be for you to say whether D13 is
the only window you have.
267 The appellant submits that the trial Judge’s comments had the effect of
neutralising an important aspect of the defence address.
268 Defence counsel, in her closing address, also relied on police videos taken of
the crime scene in 1993 (Exhibits D1 and D3) as undermining evidence of the
rigour of police practices in preventing the contamination of crime scene samples.
After summarising defence counsel’s submissions on this topic, the trial Judge
commented:
Defence counsel is certainly correct to say that crime scene procedures concerning
collection of material that may be tested for DNA generally as at 1993 were nowhere near
as rigorous as they are today and you should bear that in mind. But whether the differences
that can be pointed to in such protocols may have led to material errors in the DNA results
placed before you can be, of course, a rather different matter and I have put the prosecution
position on that, I am certainly not going to repeat it.
269 The appellant contends that the trial Judge’s comments had the effect of
weakening the defence submission on a matter in dispute, namely the issue of
contamination.
270 As to the evidence of Ms Parsons, the trial Judge read out a portion of defence
counsel’s address relating to her criticisms as to the reliability of the evidence. His
Honour then said:
Well, that is the defence position on that. You do have to remember that she did have her
headlights on, so it was not as though this was entirely dark. But in any event, the question
remains, how good were her observations, and do you accept that she is correctly reporting
to you what she saw. You saw her in the witness box, you can weigh up her evidence. It is
a matter for you.
271 It is important to note that at this stage of the summing up, and immediately
after making the impugned comments, the trial Judge warned the jury that
‘[p]eople have made mistakes, serious mistakes over the years, when purporting
to identify a person as a person who committed a crime…’ and contrasted the
evidence of Ms Parsons with an identification from a line-up. His Honour then
-- 76 of 90 --
[2023] SASCA 80 The Court
73
reminded the jury that her evidence was no more than a minor strand of
circumstantial evidence.
272 In relation to the evidence of M, the trial Judge initially directed the jury in
terms that confined defence criticisms of M’s evidence to her intoxication. That
was in fact not the focus of defence counsel’s challenge to the evidence. Rather,
her emphasis was on the absence of evidence that Mrs Poll was having an affair
with anyone, let alone the appellant, and the fact that the timing of the affair (as
per M’s account of the Warrnambool conversation) meant that it could not have
been referable to Mrs Poll. The appellant contends that the trial Judge’s directions,
in effect, withdrew two important aspects of defence counsel’s submissions on the
unreliability of M’s evidence.
273 In her closing address, defence counsel also made the submission that M’s
account of the conversation was coloured by the appellant’s subsequent arrest for
murder, in that she had obtained information about the allegations before
recounting the conversation to police. The trial Judge initially referred to that latter
submission as ‘puzzling’ and mischaracterised it as a submission that it amounted
to an ‘unusual coincidence’ as opposed to M’s account of the conversation being
coloured by the fact of his arrest.
274 However, after defence counsel raised those matters, the trial Judge properly
put defence counsel’s submissions to the jury. His Honour said:
… it is actually a chronological sequence of events as described by M of the learning of the
arrest, raising in her the memory of the conversation that had occurred and her then doing
something about it...
275 The trial Judge also reiterated defence counsel’s submission that there was
no evidence of an affair; and that the timing of the alleged affair would have placed
it after Mrs Poll’s murder, so it could not be referable to her.
276 The appellant contends that, notwithstanding those further directions, the trial
Judge did not adequately put or explain the defence case on the Warrnambool
conversation.
277 In support of the contention that the trial Judge’s summing up was
unbalanced, the appellant also relies on the following additional matters. First, the
appellant repeated his submissions in relation to Ground 1, that the trial Judge
erroneously detracted from defence counsel’s submissions that there was no
evidence of motive. Second, the appellant submitted that the trial Judge
undermined the exculpatory aspect of M’s evidence as to the Warrnambool
conversation in directing the jury that ‘Mr Poll was not the killer. You can entirely
discount him as the police have. There can be no suggestion that he was.’. Third,
the trial Judge did not give sufficient emphasis to the appellant’s denials during
the recorded telephone conversations. The appellant submits that the direction that
‘you can take into account those denials in his favour should you wish to do so’
was inadequate. Fourth, the trial Judge failed to adequately identify and
-- 77 of 90 --
[2023] SASCA 80 The Court
74
summarise the prosecution evidence relied upon by the appellant, which we have
already set out, as productive of reasonable doubt. Fifth, as to the blood and DNA
deposition evidence, the appellant submits that the trial Judge materially
undermined defence counsel’s submissions as to the problems with the chain of
evidence, and the likelihood of contamination of the crime scene samples, by
interspersing a summary of the defence position with reference to tranches of Dr
Duncan Taylor’s evidence. The appellant also contends that defence counsel’s
submissions as to contamination were effectively ridiculed by the trial Judge’s
comment that:
You will appreciate, ladies and gentleman, that saying he has been there, but he does not
know when, is a very different kettle of fish from saying something along the lines of ‘I
was there one morning of that day prior to the stabbing, I cut myself on a piece of paper,
had a bleeding nose and somehow dropped some samples, hither and dither.’ He didn’t say
anything like that, nothing like that.
278 In summary, the appellant contends that the trial Judge failed to adequately
put the defence position as to his challenge to significant aspects of the prosecution
case, and in relation to evidence relied on as being exculpatory. It is submitted that
these inadequacies, when considered against the general unbalanced nature of the
summing up, occasioned a miscarriage of justice.
279 The applicable general principles are well established. The fundamental task
of a trial judge is to ensure a fair trial. That task will involve not only instructing
the jury about the law but extends to identifying the issues and relating the law to
those issues. A trial judge must hold an even balance between the respective cases
and must fairly direct the jury’s consideration to the matters raised in an accused’s
defence.
280 In McKell v The Queen,73 the High Court considered a trial judge’s ‘broad
discretion’ to comment upon factual matters during the summing up. In allowing
the appeal, the Court held that statements by the trial Judge were so lacking in
balance as to be seen as an exercise in persuading the jury of the accused’s guilt,
were unfair to the accused; and gave rise to a miscarriage of justice.
281 Justices Bell, Keane, Gordon and Edelman relevantly observed:74
A trial judge’s “broad discretion” to comment on the facts of the case in a criminal trial is
an aspect of the power by which a trial judge discharges the fundamental task of ensuring
a fair trial of the accused. The discretion has to be exercised judicially as part of ensuring
that the facts of the case are put “accurately and fairly” to the jury. It is not exercisable, at
large, independently of the fundamental task described above. A fortiori, the trial Judge’s
summing-up is not an occasion to address the jury in terms apt to add to the force of the
case for the prosecution or the accused so as to sway the jury to either view. For that reason,
as the plurality in RPS stated, judicial circumspection is required in the exercise of the
discretion to comment.

282 Their Honours considered that the relevant question was whether:75
the trial Judge’s comments were apt to create a “danger” or a substantial risk that the jury
might actually be persuaded of the appellant’s guilt by comments in favour of the
prosecution case made with the authority of the judge.
(citations omitted)
283 As to the comments of a trial judge when the prosecution case is a strong one,
their Honours acknowledged that:76
… even a neutral summary of that case by the trial Judge may sound adverse to the accused,
but there is a real and well-recognised difference between the statement of a case and the
advocacy of that case. ... Further, the circumstance that a case against an accused person
appears a strong one in no way diminishes the obligation of those conducting the trial to
ensure that it is a fair one.
(citations omitted)
284 The extent of the duty to put the defence case is not informed by the strength
of the prosecution case, nor the trial Judge’s views as to the relative merits or
weaknesses of the defence case.77
285 In relation to the discretion of the trial Judge to comment on the parties’
respective cases, the appellant also relied on the authorities of R v Emes78 and
Pyliotis v The Queen.79
286 In R v Emes, the trial Judge commented adversely on the appellant’s
explanation for an incriminating text message. This Court ultimately found that
while the trial Judge presented both prosecution and defence submissions on that
critical issue, in a short summing up, he effectively presented a better address to
the jury than the prosecutor had done in a way that ‘improperly skewed the balance
in favour of the prosecution.’80 For that reason, the appeal was allowed.
287 In Pyliotis v The Queen, the trial Judge made a series of comments
responding to various submissions advanced by defence counsel. The Court of
Criminal Appeal of Victoria held that the comments added force to the prosecution
case and undermined the applicant’s defence. The Court considered that the
comments were not necessary to restoring an imbalance of fairness between the
prosecution and defence, nor to correct errors that might otherwise have adversely
affected the jury’s capacity to decide the case fairly on the merits; and there was a

76
real risk that the comments may have unfavourably influenced the jury’s
consideration of the defence case. The appeal was allowed.81
288 With those general principles in mind, we turn to consider the question of
whether the trial Judge adequately put the defence case and whether the trial
miscarried as a result of an unbalanced summing up. In doing so, it is necessary
to consider the summing up in its entirety in the context of the evidence led at trial
and the issues in dispute.82
289 As noted above, the ultimate issue for determination by the jury was whether
the prosecution had proved that the appellant was the offender. The prosecution
relied primarily on the blood and DNA deposition evidence. The appellant did not
give or call any evidence at trial. The appellant’s case, at trial, consisted of a
challenge through cross-examination of prosecution witnesses as to the accuracy
and reliability of the blood and DNA deposition evidence, and a reliance on other
aspects of the evidence adduced as part of the prosecution case. Accordingly, it
was inevitable that the summing up would consist largely of a summary of the
prosecution case.
290 As to the defence case on the blood and DNA deposition evidence, the trial
Judge dealt with defence submissions in detail and made express reference to: the
absence of modern safeguards for the collection and preservation of evidence;
defence exhibits which were said to provide examples of procedures being
inadequately observed (exhibits D13 and D15); videos of the crime scene
examination which cast doubt on the vigour of police crime scene examination
procedures (exhibits D1 and D3); the absence of accreditors checking the FSSA’s
handling of this case and its mistakes in paperwork; and the absence of written
records of procedures relating to DNA analysis in the FSSA’s case file.
291 The trial Judge also went on to give additional directions sought by defence
counsel as to the blood DNA and deposition evidence.
292 In relation to the trial Judge’s rebuttal comments, summarised above, we are
satisfied that the juxtaposition of the prosecution and defence positions on that
topic was simply a means of drawing the jury’s attention to competing
considerations and did not involve the trial Judge aligning himself with the
prosecution case nor deprecating the defence case.
293 As to the evidence of M, the trial Judge reminded the jury of defence counsel’s
submission that M was an ‘honestly mistaken witness’. The trial Judge addressed
the jury as to M’s level of intoxication and, as requested by defence counsel,
reminded the jury of defence counsel’s submission that her account of the
conversation was affected by the fact of the accused’s arrest. The trial Judge also
reminded the jury of defence counsel’s submission that the appellant’s account of

[2023] SASCA 80 The Court
77
the affair placed it at a time after his relationship with Ms Young had ended, and
therefore after Mrs Poll was murdered.
294 As to the other evidence relied upon in the appellant’s defence, the trial Judge
specifically referred to defence counsel’s submissions as to the unreliability of
Ms Parsons’ evidence; highlighted the absence of injury to the appellant’s hand;
referred to the absence of the appellant’s DNA under Mrs Poll’s fingernails; and,
in dealing with the shoe impressions, noted that 40 per cent of the male population
take a size nine shoe. A significant forensic disadvantage direction was given
concerning the unavailability of the appellant’s work records due to the passage of
time.
295 Having considered the trial record and the summing up as a whole, we are
satisfied that it was not unbalanced, and the trial Judge adequately presented the
defence case to the jury. We do not consider that the trial Judge’s comments,
individually or cumulatively, were apt to create a danger or a substantial risk that
the jury might actually be persuaded of the appellant’s guilt.
296 We grant permission on Ground 4A but dismiss both Grounds 4 and 4A.
Ground 5 – Directions as to the evidence of Debra Parsons and Dr Sara Jones
297 This complaint concerns the trial Judge’s directions as to the evidence of
Ms Parsons and her description of a male she observed in the vicinity of the
newsagency at around the time of Mrs Poll’s murder; and the evidence of Dr Jones
as to the unidentified shoe impressions left at the crime scene. The trial Judge
instructed the jury that both bodies of evidence were ‘consistent with’ the
prosecution case. The appellant contends that his Honour did not make clear to
the jury that the evidence did not directly implicate the appellant, and in the
absence of a direction in those terms, there exists a risk that the jury approached
the evidence as confirmatory of the appellant’s guilt.
298 In his summing up, after reciting a passage of the prosecution’s address in
relation to the evidence of Ms Parsons, the trial Judge gave the following direction:
Ladies and gentlemen, the Crown here is of course conceding that you could not convict
the accused on that basis, on the basis of that evidence of Ms Parsons alone; it is simply
not enough, but the prosecution says if you are prepared to accept that the prosecution have
established their major strand of the blood and DNA deposition evidence, then you can also
take into account other strands of varying weight. And this particular strand shows that
there was someone whose description given by Ms Parsons was consistent with having just
committed a crime of this sort, consistent, it doesn’t have to be, but consistent and,
secondly, consistent with the general appearance of the accused as he would have appeared
at that time. It is not said to be strong by itself but it is just a matter you can bear in mind
if you adopt the process that the Crown suggest you should.
In a similar way, the Crown point to the shoe print evidence, that the testing found that the
shoe was in certain parameters which were equivalent to a size 9, male shoe. It is of course
immediately disclosed to you that about 40% of the male population take a shoe size in that
range so again it is consistent with the accused but of itself could never prove a case. It
-- 81 of 90 --
[2023] SASCA 80 The Court
78
does, however, constitute even more confirmatory evidence that it was not Mr Poll, whose
shoe size was seven to seven and a half. But, as I say, it is a matter you can take into
account and give it what weight you consider it deserves.
299 Later in the summing up, after referring to defence counsel’s address as to
the evidence of Ms Parsons, and when addressing the jury as to the defence case,
his Honour said:
Well, that is the defence position on that. You do have to remember that she did have her
headlights on, so it was not as though this was entirely dark. But, in any event, the question
remains, how good were her observations, and do you accept that she is correctly reporting
to you what she saw. You saw her in the witness box, you can weigh up her evidence. It is
a matter for you.
It is the case that people can, some people can, have difficulties in making observations
and describing and remembering the appearance of other persons. Is this lady, Ms Parsons,
such a person or not? It is a matter for you. People have made mistakes, serious mistakes
over the years, when purporting to identify a person as a person who committed a crime,
and those mistakes have been later exposed.
And here, of course, no-one suggests that Ms Parsons has picked the accused out of a line-
up of people, and she does not point to him in court and say ‘That’s him’. So you do not
have any of those things. This is not a case where she purports to identify the accused as
that person she saw. But, once again, as I say, it is no more than a minor strand in the
prosecution case of consistency, rather than this is definitely the person, and so I will leave
it at that.
300 It can be seen that the trial Judge instructed the jury that on one view of
Ms Parsons’ evidence, and the shoe impression evidence, it was consistent with
the prosecution case on the issue of identity. That is, the appearance of a male in
the vicinity of the newsagency (purportedly the offender) was consistent with the
appellant’s appearance at the time of the attack in April 1993, and the size of the
unaccounted shoe impressions (inferentially worn by the offender) was consistent
with the size of shoes worn by the appellant at the time of his arrest.
301 In support of this ground of appeal, the appellant relied on the authority of
R v B and D.83 In that matter, the appellants were charged with five counts of
unlawful sexual intercourse involving the daughter of the appellant, B. The
prosecution adduced medical evidence that the state of the complainant’s vagina
and hymen were such that there could have been penile penetration. The appellant
complained about the trial Judge’s direction to the jury that the medical evidence
was ‘consistent’ with the history provided by the complainant. In allowing the
appeal, King CJ said:84
It is literally true, of course, that what Dr Moody found was consistent with the history the
girl gave and Dr Moody expressed that opinion. I think, however, that the account which
his Honour gave of the evidence of Dr Moody in the summing up was inadequate to convey
the true effect of her evidence to the jury. The expression “consistent with” is frequently
used in ordinary conversation as synonymous with “confirmatory of”. The failure of the

-- 82 of 90 --
[2023] SASCA 80 The Court
79
judge to make clear that Dr Moody’s evidence did not in any way implicate the appellants
created the risk that the jury might understand the learned judge as conveying that they
could regard Dr Moody’s evidence as tending to confirm the guilt of the appellants.
302 In relation to the evidence of Ms Parsons, the appellant submits that, as in
R v B and D, the true import of her evidence was that it was not inconsistent with
the appellant being the offender; however, it could not positively implicate the
appellant in the offence. The appellant contends that the trial Judge’s directions in
relation to the evidence of Ms Parsons created the risk that the jury understood that
it was permissible to embark upon a process of reasoning whereby the evidence
implicated the appellant.
303 In relation to the shoe print evidence of Dr Jones, the prosecution relied upon
the evidence that two unidentified shoe marks in the blood at the crime scene were
of a size nine shoe, that being the optimal fit for the appellant at the time of the
trial. There was no evidence which positively established what size shoe the
appellant wore in 1993.
304 The appellant relied on Volpe v The Queen.85 There, the appellant was
charged with murder. A male body was located in a reserve and a number of shoe
impressions were identified close to the body. Evidence was led of one such
impression being part of a shoe’s heel and arch. Approximately a year after the
deceased’s body was located, police seized a woman’s size 11 New Balance
running shoe from the appellant’s house. There was evidence that the seized shoe
could have produced the unidentified impression near the deceased’s body. The
Court of Criminal Appeal of Victoria, in allowing the appeal, held that the shoe
evidence, while relevant, was of slight probative value and should have been
excluded. Justices Priest, Forrest and Weinberg said:86
Moreover, there was no satisfactory evidence about the size of the class of New Balance
shoes sold in Victoria which could have left that impression.
…
At its highest, that evidence established no more than that a shoe with a similar – but not
necessarily identical – sole to the shoe seized could have left the impression at marker 3…
305 Their Honours concluded:87
In our view there was a real prospect that the evidence might be used by the jury as proving
more than it was capable of doing. By itself, the evidence could never have placed the
applicant at the site where the body was dumped; yet, because of its importance to the
prosecution case, it was relied upon to prove exactly that. At its highest, the evidence
proved no more than that the applicant had access to a shoe that might have left an
impression near where the body of the deceased was found, within a few hours of the body
there being dumped, and thus that the applicant - were he wearing the shoe - could have

80
dumped it. As we have said, it was a relevant piece of circumstantial evidence, but it was
afflicted by substantial limitation.
Next, the risk that the jury would conclude from the impugned evidence that the applicant
was the man who dumped the body was magnified by two things: first, the evidence being
given a cloak of authenticity by Sergeant Kohlmann’s “expert” contribution to the overall
shoeprint evidence; and, secondly, the misstatement by the judge in his charge as to how
the prosecution put its case.
306 In the present case, the appellant contends that the direction given by the trial
Judge, which erroneously permitted the jury to use the shoe impression evidence
as being consistent with the prosecution case, was highly prejudicial to the
appellant’s fair trial; and the error was compounded by the trial Judge describing
the evidence as ‘confirmatory’ in excluding Mrs Poll’s husband as the offender.
307 It is important to note at the outset that there was no challenge to the
admissibility of the evidence of Ms Parsons or Dr Jones at trial, or on this appeal.
Further, the evidence of Ms Parsons, and the shoe impression evidence, were
minor strands of the circumstantial case against the appellant and were described
in that manner by the prosecution, and indeed the trial Judge. Both bodies of
evidence were capable of supporting the prosecution case as to identity, although
individually or cumulatively they were not sufficient of themselves to prove
identity. The prosecution case rested primarily on the blood and DNA deposition
evidence.
308 In respect of the impugned directions as to Ms Parsons’ description of the
male she saw in the vicinity of the newsagency as consistent with the appearance
of the appellant, the trial Judge made plain that it did not constitute identification
evidence; and it was not direct evidence that he committed the crime. Indeed, his
Honour prefaced his directions as to both Ms Parsons’ evidence and the shoeprint
evidence by instructing the jury that it was only if they were prepared to accept as
proven the ‘major strand’ of the blood and DNA deposition evidence, that they
could take into account the other strands of evidence of varying weight.
309 The authority of R v B and D does not stand for the proposition that it is
improper or misleading for a trial judge, in the course of summing up the
prosecution case, to use the term ‘consistent with’ in relation to strands of a
circumstantial case which, of themselves, do not necessarily implicate an accused.
The impugned direction in the case of R v B and D was considered erroneous
because it failed to convey the true effect of the evidence; the direction suggested
the medical evidence was consistent with the history provided by the complainant,
when in fact the evidence was only consistent with a general allegation that
penetration had occurred.88
310 Here, the matter is quite different. The trial Judge’s directions did not elevate
the evidence of Ms Parsons or Dr Jones beyond what it could properly establish as
88 R v B and D (1993) 66 A Crim R 192 at 196 per King CJ.
-- 84 of 90 --
[2023] SASCA 80 The Court
81
part of the prosecution case. Both bodies of evidence were properly left to the jury
as minor strands of a circumstantial case, which, when considered in conjunction
with other evidence, were probative in proof of identity. As noted above, the trial
Judge expressly instructed the jury that it was only if they were prepared to accept
beyond reasonable doubt that the prosecution had established the blood and DNA
deposition evidence, that they could then take into account the other strands of
circumstantial evidence in proof of the identity of the appellant as the offender.
311 Further, as discussed earlier, the trial Judge outlined the limitations in the
evidence of Ms Parsons. In relation to the unidentified shoe impressions, the trial
Judge emphasised the limited weight to be afforded to the evidence by reminding
the jury that 40 per cent of the male population take a shoe size in the range of size
nine. As to his remarks that a shoe size nine is ‘confirmatory evidence’ that the
offender was not Mr Poll, that remark was of little moment in circumstances where
there was evidence that his shoes had been examined and excluded as having made
the shoeprint impressions.
312 For those reasons, we are satisfied that the trial Judge’s directions were not
erroneous and there was no risk that the jury approached this evidence as directly
implicating the appellant.
313 We refuse permission to appeal on Ground 5.
Ground 6 – Expert evidence of Dr Ross James and Sergeant David Veldhoen
314 This ground of appeal relates to the expert evidence of Dr James and Sergeant
Veldhoen in relation to the deposition of the appellant’s blood. The admissibility
of the impugned evidence of Dr James and Sergeant Veldhoen was not challenged
at trial.
315 The appellant complains that the admission of the evidence of Dr James, a
pathologist, that the offender may have received a cut during the attack on Mrs Poll
by his hand slipping onto the knife blade, was erroneous and resulted in a
miscarriage of justice. The appellant contends that Dr James’ opinion was
speculative given there was no evidence that the appellant had sustained an injury
to either hand at the relevant time; indeed, the evidence was to the contrary.
316 On the prosecution case, the evidence of Dr James as to the offender having
sustained a cut during the attack was significant; it linked the blood deposited at
the crime scene with the appellant (by reason of the DNA results), to the knife
attack on Mrs Poll. Sergeant Veldhoen gave evidence that a free-bleeding injury
was responsible for the various deposits of blood at the crime scene.
317 Dr James conducted a post-mortem examination on Mrs Poll. At trial, he
explained that there were 18 stab wounds near Mrs Poll’s backbone. He
considered that the wounds were inflicted while Mrs Poll was face down on the
floor. Six of the wounds were consistent with a knife having passed through
Mrs Poll’s body into the floor. There were also defensive wounds to her hands
-- 85 of 90 --
[2023] SASCA 80 The Court
82
and ‘scalping injuries.’ Dr James said that there was no reason to assume that more
than one knife was involved. He thought the blade of the knife was very strong
with an extremely sharp edge. He estimated the blade was at least 22cm in length
and that it was not a kitchen knife, but rather, a hunting knife. Dr James noted that
it was not possible to determine the movements of the offender and Mrs Poll during
the attack with any accuracy; he agreed that a stabbing involves a dynamic
situation.
318 Dr James explained that the offender’s hand may have been injured during
the attack in the following way:
… the blade being very sharp, the assailant’s hand can slip down over the blade and receive
a cut in that fashion. It is also possible, I suppose, if one wants to get involved in
choreography, for the assailant to perhaps hold some hair whilst slashing the back of the
scalp and in doing so might inadvertently cut his or her own hand. That’s speculation on
my part.
319 Dr James was asked what factors might affect the circumstances in which the
offender’s hand would slip onto the blade. He responded:
You’re drawing me out here. I suppose whether the blade comes to a sudden stop and a
vigorous thrust to a blade that suddenly stops allows the hand to slip over the bloodstained
handle and encroach on the sharp knife edge.
320 Dr James agreed blood could act as a lubricant making a slip more likely
‘given the number of injuries and how violent the soft tissue damage was, the blade
and the handle would inevitably be covered with blood.’
321 Sergeant Veldhoen gave evidence that several of the blood stains were
consistent with drip stains from a free-bleeding injury. A free-bleeding injury was
described as one which expels blood, as opposed to blood remaining adhered to
the surface. He explained that a cut that breached blood vessels was capable of
causing a free-bleeding injury. He said that blood stains in the back office and on,
or under, the interior door handle of the sole entry/exit door to the newsagency
were consistent with having been deposited by a free-bleeding injury.
322 The prosecution urged the jury to draw the inference from the combined
effect of the evidence of Dr James and Sergeant Veldhoen that the offender had
sustained a cut in the course of, or in connection with carrying out the attack on
Mrs Poll in the rear office, and then deposited blood in that office and on the
internal door handle of the sole entry/exit door when fleeing the newsagency after
the attack.
323 The appellant contends that the evidence of Dr James and Sergeant Veldhoen
was not admissible as the evidence was purely speculative and without an
evidentiary foundation. It was emphasised that both the appellant’s mother,
Ms Richardson, and his girlfriend at the time, Ms Young, said that they observed
no injuries on the appellant’s hands in April 1993.
-- 86 of 90 --
[2023] SASCA 80 The Court
83
324 The appellant contends that Dr James should not have been permitted to
speculate on the possibility that the offender sustained a free-bleeding injury
during the attack when there was no other evidence which would support that
conclusion (as that was a matter directly relevant to a fact in issue).
325 In Straker v The Queen,89 the accused was convicted of the murder of a
homosexual male. He did not dispute that he caused the deceased’s death by
striking him in the head with a hammer but raised the issue of provocation. The
pathologist who conducted the post-mortem examination gave evidence as to the
condition of the deceased’s anus and rectum, and the possible cause of that
condition. He said that it was explicable on the basis that the deceased was a person
who had regular anal intercourse and who had some form of anal interference, or
intercourse, shortly before or after death. In allowing the appeal, the High Court
held the evidence was inadmissible and prejudicial to the appellant. Justice Jacobs
said:90
The real complaint of the appellant is that Dr James was permitted to speculate on a
possibility of which there was no evidence of probability, namely, that shortly before or
after the killing, a person, who could only be the accused, had played the active role in anal
intercourse with the deceased. If there had been evidence of such anal intercourse after
death, it would have been strong evidence against the accused in two ways. First, it would
have suggested a motive for the killing, namely, necrophilia. Secondly, it would have
rebutted the defence of provocation.
The question, therefore, is whether Dr James’ speculation on possibilities which had no
basis of probability was admissible. I can see no basis upon which it was admissible. It is
true that in many circumstances an expert witness is entitled to explain the steps by which
he reaches his expert opinion. But he is not entitled to speculate on a possibility directly
relevant to the issue or a fact in issue when the speculation is adverse to the accused person
and when there is no evidence which would support a conclusion that the fact was
established. … An expert may give evidence that a condition found by him is consistent
with a certain cause, but, if the cause is in issue, such expert evidence is only admissible
against an accused if there is other evidence to support a finding of that cause. The jury
may be invited to draw inferences from the evidence but not to join an expert witness in
speculation on possibilities adverse to the accused.
326 In R v Berry,91 Redlich JA (with whom Buchanan and Kellam JJA agreed)
explained that:92
an expert will not ordinarily be permitted to speculate as to inferences when there is no
evidence that could support such an inference. Where there is such evidence, the expert
may testify that such circumstances are consistent with such an explanation. Thus, an expert
may be invited to consider whether a hypothesis is consistent with the known facts so long

110 per Stephen J, at 114 per Jacobs J.
-- 87 of 90 --
[2023] SASCA 80 The Court
84
as the hypothesis is sought to be drawn from facts which may be established by the evidence
and the assessment of such facts is within the witness’s expertise.
327 Justice Redlich also noted that the judgments in Straker v The Queen
suggested that where an inference is adverse to the accused, the expert should only
be permitted to express such an opinion where it is a probable inference from the
known facts.93
328 The broader principles that govern whether the opinion evidence of an expert
is admissible at trial are well-established. As explained in R v Dastagir:94
The principles that govern whether the opinion evidence of an expert is admissible at trial
can be reduced to two questions. First, whether the subject matter of the opinion falls within
the class of subjects upon which expert testimony is permissible. This question of itself
may be divided into two parts:
i. whether the subject matter of the opinion is such that a person without
instruction or experience in the area of knowledge or human experience
would be able to form a sound judgment on the matter without the assistance
of witnesses possessing special knowledge or experience in the area; and
ii. whether the subject matter of the opinion forms part of knowledge or
experience which is sufficiently organised or recognised to be accepted as a
reliable body of knowledge or experience, a special acquaintance with which
by the witness would render his or her opinion of assistance to the Court.
Second, whether the witness has acquired, by study or experience, sufficient knowledge of
the subject to render his or her opinion of value in resolving the issues before the Court.
329 We are satisfied that the evidence of Dr James as to the possibility of the
offender having sustained a cut during the attack on Mrs Poll was not speculative
but had an evidentiary foundation in the results of the post-mortem examination of
Mrs Poll. More specifically, the evidentiary basis for his opinion as to the offender
possibly having sustained a cut resulting in a free-bleeding injury was drawn from
the following: the nature and the number of the injuries sustained by Mrs Poll; the
size and nature of the weapon used during the attack; the likelihood that the
weapon used would have become covered in blood; the fact that blood acts as a
lubricant; and the presence of blood deposited throughout the store which were not
attributable to Mrs Poll.
330 Moreover, Dr James’ evidence on this topic did not amount to mere
speculation as to a possible explanation from an observed fact where there was no
other evidence supporting the explanation. The other evidence referred to above
was such that it was open for the jury to infer that it was likely or probable that the
offender would have sustained a cut during the attack on Mrs Poll given the attack

consisted of 18 stab wounds inflicted with a 22cm long knife to her back region
with some of the wounds penetrating through her body to the floor.
331 Nor did the evidence of Dr James extend beyond his specialised knowledge
or field of expertise. There was no challenge made to the expertise of Dr James as
a forensic pathologist or to his evidence. It is well within the expertise of a forensic
pathologist to comment on the likely mechanisms by which an injury may be
inflicted.95 The fact that Dr James, in formulating his opinion that the offender
may have sustained a cut during the attack and as to the mechanisms by which this
may have occurred, had regard to matters which were within the knowledge or
experience of lay persons (such as the likelihood that the weapon used would have
become covered in blood during the attack and that blood acts as a lubricant) did
not mean that his opinion as a whole was not based on specialised knowledge or
experience as a pathologist. As Gaudron J explained in Velevski v The Queen:96
The concept of “specialised knowledge” imports knowledge of matters which are outside
the knowledge or experience of ordinary persons and which “is sufficiently organised or
recognised to be accepted as a reliable body of knowledge or experience.” So to say,
however, is not to say that an expert witness cannot have regard to matters that are within
the knowledge of ordinary persons in formulating his or her opinion.

332 As to the concession by Dr James of ‘speculation’ in respect of the likelihood
of the offender sustaining a cut while inflicting the injuries to Mrs Poll’s scalp, we
agree with the respondent’s submission that this was a comment which went to his
relative confidence in expressing an opinion as to the mechanism of the ‘slashing
injury’ to Mrs Poll’s scalp. Dr James was simply being careful not to overstate his
evidence on this topic rather than engaging in ‘speculation.’
333 For those reasons, we are satisfied that Dr James’ opinion as to the likelihood
of the offender having received a cut or free-bleeding injury during the attack on
Mrs Poll was neither speculative nor inadmissible.
334 In relation to Sergeant Veldhoen’s evidence that the blood stains were
consistent with drip stains from a free-bleeding injury, that evidence was within
his established expertise as to blood pattern analysis and were matters on which
the jury would not be able to form a sound judgment without assistance. There
was unchallenged evidence at trial that blood pattern analysis is a discipline which
is sufficiently organised or recognised as a specialised body of knowledge, or
experience, to constitute expert evidence. There was also ample material to
establish that Sergeant Veldhoen possessed sufficient knowledge and experience
as to blood pattern analysis to provide an opinion as to his observations and
characterisation of the blood stains, and the inferences to be drawn from them.
That evidence was highly probative in explaining the mechanisms by which blood

Veldhoen was admissible as expert evidence.
