During the night of 5 October 2018, five men (Mr Howell, Mr Mitchell, Mr Rigney, Mr Carver and
Mr Tenhoopen) travelled in two cars to a location in suburban Adelaide, and then walked together to
a nearby house which was being used to grow cannabis. They had agreed with each other that they
would steal a substantial amount of cannabis from this grow house.
As they approached the grow house on foot, one of the men could be seen from CCTV footage to be
carrying a long object, variously described as a stick, pole or bat. They broke into the grow house,
where the deceased was present and guarding the cannabis. Whilst some of the men were stripping
and bagging the cannabis, one or more of the men violently assaulted the deceased with at least one
blow to his head, causing his death.
The men loaded multiple bags of cannabis into the deceased’s car, which was in the driveway of the
grow house, and left in that car. After returning to where they had left their cars, they drove to
another location, where they transferred the cannabis into one of their own cars. They then drove in
their cars to Murray Bridge, where they divided the cannabis amongst themselves.
The men were all subsequently charged with murder, with the prosecution case against each
encompassing allegations of both common law murder by reason of an extended joint criminal
enterprise, and constructive murder by reason of a joint criminal enterprise.
All defendants elected for trials by judge alone. Mr Howell was tried separately before Stein J, who
acquitted him of murder but convicted him of manslaughter. The other defendants were jointly tried
before McIntyre J, who found them all guilty of murder (by reason of a joint criminal enterprise to
commit constructive murder).
The Director of Public Prosecutions seeks permission to appeal Mr Howell’s acquittal, and the
remaining defendants seek permission to appeal their convictions.
The Director’s proposed appeal raises complaints challenging the judge’s approach and conclusions
in relation to the scope of the agreement or joint criminal enterprise to which Mr Howell was party.
In particular, he challenges Stein J’s conclusion to the effect that Mr Howell agreed only to violence
for the purpose of subduing the deceased, and did not agree to the possibility violence ‘of the same
general nature’ as that which occurred and caused death.
The defendants’ proposed appeals raise a number of overlapping grounds, including complaints to
the effect that their verdicts of guilty were unreasonable by reason, inter alia, that there was no basis
in the evidence to find that the item seen in the CCTV footage was used to kill the deceased, that the
agreement between the defendants did not extend to the possibility of violence of ‘the same general
nature’ as that which occurred and caused death, and that the agreement was no longer on foot when
the deceased was killed.
It was also argued that the verdicts were inconsistent with: McIntyre J’s own rejection of the
prosecution case on common law murder on the basis that it had not been proved that the defendants
foresaw that one of their number might use a weapon to assault an occupant of the grow house with
an intention to cause death or grievous bodily harm; and / or Stein J’s acquittal of Mr Howell on the
basis that it had not been proved that he agreed to the possibility of violence of ‘the same general
nature’ as that which occurred and caused death.
The defendants also raised several specific complaints relating to McIntyre J’s treatment of certain
aspects of the evidence, as well as a general complaint about the adequacy of her reasons.
On the Director’s appeal against Mr Howell’s acquittal:
Held (per S Doyle JA, Livesey P and B Doyle AJA agreeing) granting permission to appeal but
dismissing the appeal:
1. The judge adequately addressed the prosecution’s second pathway to guilt, namely
constructive murder by reason of a joint criminal enterprise.
-- 2 of 84 --
2. The requirement that the defendant agree the possibility of violence of ‘the same general
nature’ as that which occurred and caused death is merely an aspect of the scope of the
agreement founding liability for joint criminal enterprise.
3. No error of principle has been established in Stein J’s conclusion that the prosecution failed
to establish that Mr Howell agreed to the possibility of violence other than for the purpose of
subduing any occupant of the grow house, and hence did not agree violence of ‘the same
general nature’ as that which occurred and caused death.
4. The judge’s factual finding to this effect was at least reasonably open, and any error in this
respect would not, in any event, be a proper basis for this Court’s intervention on a Crown
appeal.
5. The Director’s appeal raises issues of principle of sufficient general importance that there
should be a grant of permission to appeal. However, no error of principle, or other error
appropriate for this Court’s intervention has been established and the appeal should be
dismissed.
On the appeals by Mr Mitchell, Mr Rigney, Mr Carver and Mr Tenhoopen:
Held (per S Doyle JA, Livesey P and B Doyle AJA agreeing) granting permission to appeal but
dismissing the appeals:
1. The various contentions to the effect that McIntyre J’s verdicts of guilty of constructive
murder by reason of a joint criminal enterprise have not been made out.
2. It was established that the defendants agreed to the possibility of violence using the item that
one of them was seen holding in the CCTV footage.
3. The agreement between the defendants was still on foot at the time of the fatal blow or blows.
4. There was no relevant inconsistency with McIntyre J’s rejection of the prosecution case of
common law murder by reason of extended joint criminal enterprise.
5. The challenges made to the judge’s treatment of certain aspects of the evidence, and to the
adequacy of her reasons more generally, have not been made out.
6. The judge’s conclusion that the defendants agreed to the possibility of violence of the same
general nature as that which occurred and caused death, and hence her verdicts of guilty of
murder, were open. The verdicts are not unreasonable.
7. There is no relevant inconsistency between the verdicts of McIntyre J and Stein J given that
they arose in different trials, with material differences in the evidence led at each.

KING
[2026] SASCA 71
Court of Appeal – Criminal: Livesey P, S Doyle JA and B Doyle AJA
LIVESEY P AND B DOYLE AJA:
Introduction
1 These appeals follow two trials by judge alone. In the first, the defendant
Mr Howell was acquitted of murder but convicted of manslaughter.1 In the second,
the defendants Mr Mitchell, Mr Rigney, Mr Carver and Mr Tenhoopen, were
convicted of murder.2 The prosecution appealed Mr Howell’s acquittal and the
other defendants appealed their convictions. All require permission to appeal. Both
trials addressed similar, but not identical, facts concerning the death of Mr Gjabri
from blunt force trauma to the head, after the defendants forcibly entered a
marijuana ‘grow house’ he was guarding. The evidence showed that one of the
defendants was carrying a long object. The arguments about criminal liability of
the defendants under the principles concerning joint criminal enterprise, extended
joint criminal enterprise and constructive murder largely turned on matters of
inference.
2 For the reasons given by S Doyle JA, in each appeal permission should be
granted but the appeal dismissed.
Different trials, different outcomes
3 The effect is that, on similar facts, criminal liability has been decided
differently concerning the same homicide in each trial. Whilst this might be
thought to involve some tension, that is explained by two differences between
these trials. The first is that the evidence and the way in which it was presented
and argued was not the same. Secondly, and more importantly, the trials were
heard by different triers of fact. Whilst in many cases the factual findings that
might be made, and the inferences and conclusions drawn, on the same evidence
may be decided in the same way by different juries or judges, that proposition is
far from immutable.
4 Where a particular trier of fact has been assigned responsibility to hear a trial,
determine the facts and decide guilt, certain constraints aside, those are matters for
that jury or judge and no other. As ‘the constitutional tribunal for deciding issues

2
of fact’,3 that jury or judge will have room for decisional freedom.4 It will be for
that jury or judge to decide the facts and return the verdict which they believe best
accords with their oath and duty.5
5 The constraints on decisional freedom by a jury or judge when determining
guilt include the obligation to decide the case on the evidence led and the
arguments made in the case, to heed directions of law and the proper scope for
appellate intervention. The jury or judge must decide the case according to law and
its own view of the facts, for criminal liability must usually be decided at a trial by
the jury or judge assigned to hear the case.
6 A familiar constraint on the trier of fact represented by appellate intervention
concerns cases where the defendant contends that the verdict was unreasonable or
not supported having regard to the evidence, under s 158(1)(a) of the Criminal
Procedure Act 1921 (SA). It is for the appeal court to review the record for itself
and consider whether it entertains a reasonable doubt about guilt. However, even
in that setting it may be necessary for the appeal court to recognise and give
deference to the decisions made by the trier of fact. That may be because the trier
of fact has heard the evidence and decided the case with advantages that cannot be
replicated on appeal, including because it may matter how the evidence was given
or how the trial unfolded, whether before a jury,6 or a trial by judge alone.7
7 The room for decisional freedom is recognised by an appeal court with
hindsight, by asking whether a finding or verdict was ‘open’ to the trier of fact.
That is reflected by the appeal court considering whether, upon the whole of the
evidence, it was not open to the jury to be satisfied beyond reasonable doubt that

4 Which is to be distinguished from the way in which the term ‘the area of decisional freedom’ has been
used in the very different administrative law context. In Minister for Immigration and Citizenship v Li
(2013) 249 CLR 332 at [28], French CJ referred to this as the area in which ‘reasonable minds may
reach different conclusions about the correct or preferable decision’.
5 See, for example, in the case of jury verdicts in the same trial which might be thought inconsistent,
MacKenzie v The Queen (1996) 190 CLR 348 at 364-368 (Gaudron, Gummow and Kirby JJ).
6 ‘It is only where a jury’s advantage in seeing and hearing the evidence is capable of resolving a doubt
experienced by a court of criminal appeal that the court may conclude that no miscarriage of justice
occurred’: M v The Queen (1994) 181 CLR 487 at 494 (Mason CJ, Deane, Dawson and Toohey JJ). See
SKA v The Queen (2011) 243 CLR 400 at [13] (French CJ, Gummow and Kiefel JJ).

the accused was guilty,8 or ‘whether the jury must, as distinct from might, have
entertained a doubt about the appellant’s guilt’.9
8 Having reviewed the record and reasons with the benefit of the arguments
made at the joint trial and on appeal, it was open to McIntyre J to be satisfied of
guilt beyond reasonable doubt. The other challenges made by the defendants
should be rejected for the reasons given by S Doyle JA and their appeals dismissed.
The Director’s appeal against an acquittal
9 Similarly, a review of the record and reasons with the benefit of the Director’s
arguments does not demonstrate that the acquittal and verdict concerning
Mr Howell was affected by material error or was not open to Stein J.
10 In the case of a prosecution appeal against an acquittal, there are additional
considerations bound up in the limited dispositive powers available to this Court,
notwithstanding the ostensibly broad scope for an appeal ‘on any ground’ and,
critically, the need to give consideration to double jeopardy principles having
regard to the importance of an acquittal following a criminal trial, whether in
connection with the requirement for permission or the exercise of the residual
discretion.10
11 Whilst, ultimately, the Director has not established that Stein J’s reasons
disclose any error of law, the submissions advanced by the Director canvassed
questions of principle and general importance. It is therefore appropriate to grant
permission to appeal against Mr Howell’s acquittal, notwithstanding the weight to
be given to double jeopardy considerations.11
12 However, as S Doyle JA has observed, those considerations may also inform
the nature and exercise of the Court’s jurisdiction in an appeal brought pursuant to
s 157(1)(b)(i) of the Criminal Procedure Act 1921 (SA).
13 The nature of that jurisdiction is also informed by sub-ss 158(4) and 158(5),
which enumerate and circumscribe this Court’s dispositive powers. Two aspects
of those provisions may be noted. First, the powers are discretionary. In the
exercise of discretion, it may be appropriate that double jeopardy considerations
be brought to bear.12 Secondly, the Court’s dispositive powers where an acquittal

The Queen (1997) 191 CLR 439 at 450-451 (Gaudron, McHugh and Gummow JJ), MFA v The Queen
(2002) 213 CLR 606 at [25] (Gleeson CJ, Hayne and Callinan JJ), SKA v The Queen (2011) 243 CLR
400 at [11] (French CJ, Gummow and Kiefel JJ), R v ZT (2025) 281 CLR 137 at [9]-[12] (Gageler CJ,
Gleeson, Jagot and Beech-Jones JJ), at [86]-[90] (Gordon, Edelman and Steward JJ). As for a trial by
the judge alone under s 7(1) of the Juries Act 1927 (SA), see Dansie v The Queen (2022) 274 CLR 651.

10 Recognised in cases such as R v Brougham (2015) 122 SASR 546 at [65]-[66] (Peek J, Gray and
Nicholson JJ agreeing): ‘it will be necessary for the Court to also consider whether permission to appeal
is warranted in all the circumstances and, even if it is, whether the appeal should nevertheless still be
dismissed pursuant to the residual discretion connoted by the use of the term “may allow”’.

is to be quashed do not extend to the entering of a conviction, nor the giving of a
direction to the court that is to retry the accused that the accused should be
convicted.13
14 That limitation upon this Court’s dispositive powers may suggest that, whilst
s 157(1)(b)(i) contemplates an appeal ‘on any ground’, and is not therefore limited
to appeals concerning questions of law, the Court should be reluctant to intervene
where the only basis upon which it might do so is a difference in opinion as to the
ultimate inference to be drawn from the evidence, that is, on the basis of a
disagreement as to the appropriate verdict. It is one thing to direct a retrial where
an independent review establishes that the judge misapprehended the effect of
important evidence, demonstrably erred in respect of an intermediate finding of
fact that was material to the verdict, denied the parties procedural fairness or
overlooked an important argument mounted by the prosecution so as to have
provided inadequate reasons.14 It is another to do so merely on the basis that, on
fine balance, the appeal court might form a different view as to the verdict that it
would have entered.
15 If the Court were to direct a retrial in a case of that kind, it would leave a
judge hearing the retrial in an invidious position. Supposing the evidence on the
retrial is materially identical, will a verdict of acquittal inevitably be subject to the
same challenge? If so, is the retrial a compromised exercise? If not, what purpose
was served by ordering the retrial? These considerations may suggest that
assuming, consistently with prevailing authority,15 the appeal is by way of
‘rehearing’, it is one the precise nature of which is heavily informed by matters of
context.16
16 Whether these considerations go to the nature of the errors that may warrant
intervention or manifest only in the exercise of a residual discretion need not be
resolved. Even if this Court was to conclude that based on an independent
assessment of the evidence it is persuaded beyond reasonable doubt that the scope
of any agreement extended to the carrying out of a strike of the same general nature
as the fatal blow(s), this conclusion would be reached on relatively fine balance
about a matter of fact, and without concluding that the judge’s verdict was
unreasonable or perverse.
17 In circumstances where the consequence of quashing the conviction would
be to subject Mr Howell to a third trial for murder, the prosecution appeal should
be dismissed.

Conclusion
18 We agree with the orders proposed by S Doyle JA.

19 S DOYLE JA: During the night of 8 October 2018, the defendants (Mr Howell,
Mr Mitchell, Mr Rigney, Mr Carver and Mr Tenhoopen) travelled in two cars to a
location in Para Vista. They then walked together to a nearby house on Carousel
Street which was being used to grow cannabis. They had agreed with each other
that they would steal a substantial amount of cannabis from this grow house.
20 As they approached the grow house on foot, one of the defendants could be
seen from CCTV footage to be carrying a long object, variously described as a
stick, pole or bat. They broke into the house, where the deceased (Mr Gjabri) was
present and guarding the cannabis. While some of the defendants were stripping
and bagging the cannabis, one or more of the defendants violently assaulted
Mr Gjabri with at least one blow to his head, causing his death.
21 The defendants loaded multiple bags of cannabis into the deceased’s car,
which was in the driveway of the grow house, and then left in that car. They drove
to where they had left their two cars, and then drove all three cars to a location on
Gilbert Street, Ingle Vale, where they were observed transferring the cannabis
from the deceased’s car to one of the other cars. They left that location in their
two cars, and drove to Murray Bridge, where they divided the cannabis amongst
themselves.
22 The defendants were all subsequently charged with murder, with the
prosecution case against each encompassing allegations invoking the principles of
joint criminal enterprise, extended joint criminal enterprise and constructive
murder.
23 All defendants elected for trials by judge alone. Mr Howell was tried
separately before Stein J, who acquitted him of murder but convicted him of
manslaughter. The other defendants were jointly tried before McIntyre J, who
found them all guilty of murder.
24 The prosecution seeks permission to appeal Mr Howell’s acquittal, and the
other defendants seek permission to appeal their convictions. The proposed
appeals raise a range of overlapping issues, including in relation to the operation
of the principles governing joint criminal enterprise, extended joint criminal
enterprise and constructive murder. However, as the evidence and forensic
contests differed between the two trials, and the grounds of appeal raise issues of
fact, it is necessary to address the appeals separately.
25 For the reasons which follow, I would dismiss both appeals.
26 The Director’s appeal against Mr Howell’s acquittal raises some important
issues of principle, particularly in relation to the requirement of liability for
constructive murder pursuant to a joint criminal enterprise that the defendant agree
the possibility of violence of ‘the same general nature’ as the intentional act of
violence that caused the deceased’s death. It is appropriate that the Director have
permission to appeal. However, having considered Stein J’s reasons closely, the
-- 10 of 84 --
[2026] SASCA 71 S Doyle JA
7
Director has not identified any error of law or principle. To the extent that I have
some reservations about her Honour’s ultimate conclusion as to the nature of
violence that was agreed, this involves an issue of fact. In circumstances where
her Honour’s conclusion was at least open on the evidence, I am not persuaded
that this Court should intervene.
27 The appeals brought by the defendants in the joint trial before McIntyre J
raise a number of issues. However, as I shall explain, none of the proposed
grounds of appeal have been made out. There is a tension between McIntyre J’s
conclusion that the defendants agreed the possibility of violence of the same
general nature as that which caused Mr Gjabri’s death, and Stein J’s conclusion to
the opposite effect in Mr Howell’s trial. However, there is no operative
inconsistency in circumstances where there were separate trials and material
differences in the evidence admissible against the various defendants. It has not
been established that McIntrye J’s verdicts of guilty of constructive murder
pursuant to a joint criminal enterprise were unreasonable. Nor have any of the
defendants’ other complaints been made out. I would grant the defendants in the
joint trial permission to appeal, but dismiss their appeals.

PART A: SOME MATTERS OF GENERAL PRINCIPLE
29 Given the issues raised on appeal, it is appropriate to commence with some
matters of general principle in relation to common law murder, joint criminal
enterprise, extended joint criminal enterprise and constructive murder.
Common law murder
30 Murder is a statutory offence under s 11 of the Criminal Law Consolidation
Act 1935 (SA) (‘CLCA’). However, the elements of that offence reflect the
common law offence of murder; namely, that a person, by a voluntary and
deliberate act or acts, unlawfully caused the death of another person, and did so
with the intention either to kill or cause grievous bodily harm (sometimes
described as really serious bodily harm). Hence it remains common, and
appropriate, to refer to a defendant’s liability for common law murder.
31 As will be seen, a defendant may be found guilty of common law murder
through an application of the principles governing either a joint criminal enterprise
or an extended joint criminal enterprise. However, when the pathway to guilt
relied upon by the prosecution involves constructive murder, only the principles
governing a joint criminal enterprise are applicable.
Joint criminal enterprise
32 The doctrine of joint criminal enterprise, or JCE, is a means of establishing
the liability of a defendant which is distinct from aiding, abetting, counselling or
procuring. It operates where a defendant reaches an agreement with one or more
other people to commit a crime and then, in accordance with their continuing
agreement, one or more of the parties to that agreement does, or they do between
them, all things necessary to commit that crime.

33 The principles governing liability for a JCE were described in the following
terms by the High Court in McAuliffe v The Queen:17
The doctrine of common purpose applies where a venture is undertaken by more than one
person acting in concert in pursuit of a common criminal design. Such a venture may be
described as a joint criminal enterprise. Those terms – common purpose, common design,
concert, joint criminal enterprise – are used more or less interchangeably to invoke the
doctrine which provides a means, often an additional means, of establishing the complicity
of a secondary party in the commission of a crime. The liability which attaches to the
traditional classification of accessory before the fact and principal in the second degree
may be enough to establish the guilt of a secondary party: in the case of an accessory before
the fact where that party counsels or procures the commission of the crime and in the case
of a principal in the second degree where that party, being present at the scene, aids or abets
it commission. But the complicity of a secondary party may also be established by reason
of a common purpose shared with the principal offender or with that offender and others.
Such a common purpose arises where a party reaches an understanding or arrangement
amounting to an agreement between that person and another or others that they will commit
a crime. The understanding or arrangement need not be express and may be inferred from
all the circumstances. If one or other of the parties to the understanding or arrangement
does, or they do between them, in accordance with the continuing understanding or
arrangement, all those things which are necessary to constitute the crime, they are all
equally guilty of the crime regardless of the part played by each in its commission.
34 As the Court then added, liability pursuant to a JCE extends to any crime
falling within the scope of the parties’ agreement:18
Not only that, but each of the parties to the arrangement or understanding is guilty of any
other crime falling within the scope of the common purpose which is committed in carrying
out that purpose. Initially the test of what fell within the scope of the common purpose was
determined objectively so that liability was imposed for other crimes committed as a
consequence of the commission of the crime which was the primary object of the criminal
venture, whether or not the other crimes were contemplated by the parties to that venture.
However, in accordance with the emphasis which the law now places upon the actual state
of mind of an accused person, the test has become a subjective one and the scope of the
common purpose is to be determined by what was contemplated by the parties sharing that
purpose.
35 More recently, in Mitchell v The King, the principles of JCE were restated by
Gordon, Edelman and Steward JJ:19
The doctrine of joint criminal enterprise or common enterprise is based on agreement (also
expressed as common purpose, design or enterprise). Whether the agreement is expressed
in words or inferred ‘from the parties’ conduct’, each party to an agreement to commit a
crime will be guilty of the agreed crime and any crime ‘within the scope of the agreement’.
It is therefore essential to identify what acts and omissions the parties agreed upon. The
agreement need not be express and may be an inference drawn from the parties’ conduct,
but it must be subjectively appreciated by the accused. The scope of such an agreement

(Miller) at [4] (the Court)).

10
has therefore been expressed as involving matters that each party subjectively considered.
In this respect, ‘it is essential to identify what the parties did agree upon and what it was
that each contemplated might occur’, which requires consideration of whether each party
contemplated the criminal acts ‘as a possible incident of the execution of their agreement’.
But the jury must be satisfied that each party subjectively agreed (authorised or assented)
to the conduct, including the criminal act. Hence, the ‘true position’ for nearly two
centuries has been that ‘if one of the [parties to the agreement] goes beyond what has been
tacitly agreed as part of the common enterprise, [the other party] is not liable for the
consequences of that unauthorised act’.
36 And by Kiefel CJ:20
Each of the parties to a joint criminal enterprise is equally guilty of the crime that is the
object of the enterprise and which is committed, so long as the agreement to commit it
(which may be express or inferred) remains on foot. That is so regardless of the part each
has played in its commission. Each party is also guilty of any other offence (‘the incidental
offence’) which is committed by a co-venturer that is within the scope of the agreement.
The incidental offence will be within the scope of the agreement to commit the first-
mentioned crime if the parties contemplate its commissions as a possible incident of the
execution of their agreement.
37 It is apparent from these articulations of the relevant principles that the fact
and scope of an agreement between the parties are fundamental to joint enterprise
liability. As to the fact of an agreement, it should be emphasised that the agreement
need not be express, let alone planned; it may be inferred from conduct, and arise
essentially spontaneously. As to the scope of an agreement, the charged offence
must be within the scope of what the parties subjectively agreed. References to
the charged offence being within the ‘contemplation’ of the parties, or being a
‘possible incident’ of the execution of the parties’ agreement must be understood
in this context. Put in positive terms, an ‘incidental offence’ will be within the
scope of agreement if the parties agree that it may be committed as a possible
incident of the commission of the agreed criminal act.
38 Whilst it is sometimes said that the criminal act must be an intended part of
the agreed enterprise, it is sufficient that it be ‘contingently and reluctantly’
intended as part of that agreed enterprise.21 In other words, an agreement might be
in terms that violence, or violence of a particular type or nature, may be used if
that becomes necessary.
39 It is not a requirement of liability pursuant to a JCE that the defendant be
present at the scene of the crime. It is sufficient that the defendant participated in
the joint enterprise. On the other hand, presence may suffice to establish
participation where it is in furtherance of the joint enterprise.22

40 Liability pursuant to a JCE is a form of primary liability, based upon
principles of agency. The acts of the perpetrator that are within the scope of the
agreement, and therefore done with the authority of the other parties, are attributed
to the other parties to the agreement.23
41 Liability for the offence of murder may be established through the principles
of JCE. It may be established by attributing to a defendant the acts of murder if he
was party to a JCE, provided that those acts of murder were within the scope of
the relevant agreement.24 The scope of the agreement must encompass the
possibility that a co-participant may cause death with murderous intent (that is,
with an intention to cause death or grievous bodily harm).
Extended joint criminal enterprise
42 The doctrine of extended joint criminal enterprise, or EJCE, extends a
secondary party’s liability beyond the scope of the parties’ agreement. It extends
liability to an incidental offence where the defendant has not agreed to the
commission of that crime, but the defendant nevertheless foresaw or contemplated
the possibility of the commission of that crime as an incident of the parties’ joint
enterprise, and continued to participate in the enterprise.
43 As the Court explained in McAuliffe:25
… where one party foresees, but does not agree to, a crime other than that which is planned,
and continues to participate in the venture … the secondary offender in that situation is as
much a party to the crime which is an incident of the agreed venture as he is where the
incidental crime falls within the common purpose. Of course, in that situation the
prosecution must prove that the individual concerned foresaw that the incidental crime
might be committed and cannot rely upon the existence of the common purpose as
establishing the state of mind. … the criminal culpability lies in the participation in the
joint criminal enterprise with the necessary foresight and that is so whether the foresight is
that of an individual party or is shared by all parties. That is in accordance with the general
principle of the criminal law that a person who intentionally assists in the commission of a
crime or encourages its commission may be convicted as a party to it.
44 Similarly, in Mitchell, Gordon, Edelman and Steward JJ described the
doctrine of EJCE in the following terms:26
The doctrine of ‘extended joint criminal enterprise’, as the name suggests, involves an
extension, beyond the scope of the agreement, of responsibility for a joint criminal
enterprise. In Miller, the doctrine of extended joint criminal enterprise was expressed to
apply where a party to a joint criminal enterprise has not agreed to the commission of a
crime but has instead foreseen the commission of that crime in the course of carrying out
the agreement and continues to participate in the enterprise. What is to be foreseen is that
an incidental crime might be committed, being all elements of that crime.

[2026] SASCA 71 S Doyle JA
12
45 The other members of the Court in Mitchell described the doctrine in similar
terms.27 In particular, Kiefel CJ said:28
The principle of extended joint criminal enterprise liability arises where a party to a joint
criminal enterprise foresees, but does not agree to, the commission of an incidental crime
in the course of carrying out the agreement. That is to say, the principle applies where the
commission of an incidental offence lies outside the scope of the common purpose but is
nevertheless contemplated as a possibility. The parties are each criminally liable for the
incidental offence if with foresight of the possibility that it might be committed they
nevertheless continue to participate in the enterprise and that is so whether the foresight is
that of an individual party or is shared by all the parties. Criminal culpability of this kind
is consistent with the general principle that a person who assists or encourages the
commission of an offence may be convicted as a party to it.
46 By way of illustration of the application of this doctrine, the Court referred
to a scenario where a defendant knows that another party to the joint criminal
enterprise is carrying a weapon which may be used to kill or inflict grievous bodily
harm in carrying out the enterprise. The defendant may not agree to the use of the
weapon, and indeed may reject any agreement for its use. But if they nevertheless
continue with the enterprise they will be liable for the consequences.29
47 It follows that, for the purposes of EJCE, the defendant’s contemplation of
the incidental offence reflects a subjective or actual contemplation that the
incidental offence may be committed. But, unlike JCE, it does not depend upon
an agreement that encompasses the possibility that it may be committed.
48 In the context of an allegation of murder invoking the principles of EJCE, the
necessary foresight of murder requires that the defendant contemplate the
possibility that another party to the agreement may, as an incident of carrying out
that agreement, commit an act that kills or inflicts grievous bodily harm, and do so
with ‘murderous intent’ (that is, intending to cause death or grievous bodily
harm).30
49 Contemplation of the commission of an offence necessarily entails
contemplation of conduct of a kind by which the offence might be committed. For
those offences, like murder, which include an element that the offending conduct
achieve a certain result, it would seem that the defendant must also contemplate
that result.31 That said, in Mitchell, Gordon, Edelman and Steward JJ accepted that
foresight of death ‘followed naturally’ from the foresight of grievous bodily harm
inflicted with murderous intent, given that it was only necessary that acts of ‘the
general nature’ of the attributed act be foreseen:32
27 Mitchell at [15] (Kiefel CJ), [33] (Gageler, Gleeson and Jagot JJ).

[2026] SASCA 71 S Doyle JA
13
… foresight of the possibility of death naturally follows from foresight of really serious
bodily injury (a common paraphrase of grievous bodily harm). This is particularly so since
it must also be proved that the accused foresaw the possibility that the perpetrator would
act with murderous intent and only acts of the general nature of the attributed act need to
be foreseen. Consistently with the liability for murder being imposed upon a primary
offender who intends only to cause the consequence of grievous bodily harm, the foresight
required of the secondary offender is that ‘death or really serious bodily injury might be
occasioned’ by a co-venturer acting with the intention to cause death or really serious
bodily injury.
For these reasons, in each of Gillard v The Queen, Clayton v The Queen, and Miller, it
would not have made a difference whether the foresight of the possible consequence was
described as one of only death or as one of either death or grievous bodily harm. Foresight
of the possibility of the latter is treated as involving equivalent culpability as foresight of
the possibility of the former, in the same way as intention to cause death is treated as
involving equivalent culpability as intention to cause grievous bodily harm. In Gillard, the
prosecution case of foresight was based on allegations that Mr Preston had been hired to
kill the victim and had gone to the victim's workshop with a loaded gun. In Clayton, the
prosecution case of foresight was that the assault on the victim lasted 30 to 40 minutes and
involved the use of metal poles and a large carving knife. In Miller, the prosecution case of
foresight was based on an assault using weapons including a 332 mm long knife, a baseball
bat, and a shovel.
If, however, a participant in a joint criminal enterprise foresees only the elements of a lesser
crime than the crime for which the primary offender is convicted, then the participant can
only be convicted of that lesser crime under the principles of extended joint criminal
enterprise. For example, a participant in a joint criminal enterprise of robbery might foresee
the possibility that the primary offender would cause very serious bodily harm or death to
another person but might not foresee the possibility that the primary offender would do so
with murderous intent. In that circumstance, even if the primary offender is convicted of
murder, the participant can only be convicted of manslaughter under the principles of
extended joint criminal enterprise.
50 Later in their reasons, their Honours confirmed that it was necessary, for the
purposes of liability for common law murder invoking the principles of EJCE, that
the prosecution establish that the defendant foresaw the consequence of death or
grievous bodily harm, albeit that this might be a very short step from foresight that
a co-venturer might act with murderous intent:33
The trial judge directed the jury that they could only find that an accused person was guilty
of murder under the pathway of common law murder based on extended joint criminal
enterprise if the prosecution had proved beyond reasonable doubt that the accused foresaw
that a participant to the joint criminal enterprise might inflict violence with an intention of
causing death or really serious bodily harm. But the trial judge erred by failing to direct
the jury that for common law murder based on extended joint criminal enterprise the
accused must also foresee the consequence of death or really serious bodily harm. In many
cases, foresight of this consequence might be a very short step from foresight that a
participant might act with murderous intention. The direction that the trial judge should
have given in relation to extended joint criminal enterprise is one in which it was explained
that conviction depended upon proof beyond reasonable doubt that the accused foresaw

[2026] SASCA 71 S Doyle JA
14
that in the commission of that crime there as a possibility that another person, with intent
to do so, would cause really serious bodily harm or death.
51 The rationale for EJCE differs from the rationale for JCE. Unlike JCE, it
does not involve the attribution of the acts of another which are authorised by
reason of being within the scope of the parties’ agreement. Rather, the rationale
for EJCE lies in the defendant being regarded as intentionally assisting in the
commission of a crime by continuing to participate in an enterprise with foresight
of the possibility of that crime. It is not a form of primary liability. Rather, the
liability of the defendant is a form of secondary or derivative liability which is
derived from, and dependent upon, the criminal liability of another for the foreseen
crime which was not part of the agreement.34
Constructive murder
52 Section 12A of the CLCA provides that a person who commits an intentional
act of violence, while acting in the course or furtherance of a major indictable
offence punishable by imprisonment for 10 years or more, and thus causes the
death of another, is guilty of murder.
53 Section 12A does not create a separate offence. It is, instead, another
pathway to establishing the offence of murder under s 11 of the CLCA. It, in
effect, alters the common law constructive murder rule that would otherwise have
applied under s 11.35
54 There is no difficulty with imposing liability for constructive murder through
the principles applying to a JCE. Although the requirements of s 12A focus upon
the conduct and state of mind of the primary offender who committed the relevant
act, where that occurs within the scope of the parties’ agreement, there is no
difficulty with attributing that act to a defendant who is a party to that agreement.36
As Kiefel CJ said in Mitchell:37
The principle of joint criminal enterprise has been held to apply to common law felony
murder and to constructive murder under s 12A. As to the latter, in Arulthilakan v The
Queen the application of the principle does not appear to have been doubted. The co-
accused of the two appellants stabbed and killed a person in the course of the robbery. Both
appellants were aware that he was in possession of the knife which was used. It was
observed that the plan was to ‘roll’ the deceased. That involved robbery accompanied if
necessary by force and the use of force was therefore within the scope of the agreement.
55 Liability for constructive murder pursuant to a JCE requires that the
prosecution establish that the defendant was party to an agreement to commit the
relevant major indictable offence, and that the agreement included the possible

15
commission, in the course of or in furtherance of that offence, of an intentional act
of violence of ‘the same general nature’ as that which caused the death.38
56 As Gordon, Edelman and Steward JJ explained, it is not necessary that the
agreement extend to ‘the precise manner in which the act was committed.’ Rather,
it is sufficient for the scope of the agreement to extend to acts ‘of the general nature
of the attributed act.’39 Their Honours referred in this context to a decision to the
effect that it did not prevent a conviction for constructive murder, through a JCE
involving an agreement to rob, that the robbery varied ‘in the manner of execution
of [the] agreed plan … [O]bviously it must have been a plan to rob with some
degree of violence’.40 Their Honours concluded their reasons by summarising the
position as follows:41
Where, in the case of joint criminal enterprise, an accused is alleged under s 12A to be a
party to an agreement to commit the major indictable offence alleged by the prosecution, it
would require a jury to be satisfied beyond reasonable doubt that the accused was a party
to an agreement to commit the major indictable offence and that the agreement included
the possible commission of an intentional act of violence of the same general nature as that
which caused the death42.
57 Gageler, Gleeson and Jagot JJ expressly agreed with this paragraph from their
colleagues’ reasons,43 and hence with the proposition that the parties’ agreement
must extend to the possible commission of an intentional act of violence of ‘the
same general nature’ as that which caused the death.
58 However, each of the members of the Court in Mitchell held that the
principles of EJCE were not engaged by s 12A.44 Although their Honours’
reasoning differed in their relative emphasis upon matters of statutory
construction, coherence and the appropriate breadth of criminal responsibility, the
net effect is that the Court unanimously held that s 12A does not permit a pathway
to murder by combining the operation of the doctrines of constructive murder and
EJCE. Mere foresight of (as opposed to agreement to) the relevant possibility will
not suffice to establish liability for constructive murder.

PART B: APPEAL IN HOWELL
The trial
59 In alleging at trial that Mr Howell was guilty of murder, the prosecution relied
upon two alternative pathways to guilt.
60 The first pathway was guilt through common law murder, applying the
principles of EJCE. This pathway involved a contention that Mr Howell was party
to an agreement to commit aggravated robbery with the use of any necessary
violence, and that he foresaw that one of his co-venturers might inflict violence on
the occupant of the premises with the intention of causing death or grievous bodily
harm.
61 The second pathway was guilt through constructive murder under s 12A of
the CLCA, applying the principles of JCE. This pathway involved a contention
that Mr Howell was party to an agreement to commit aggravated robbery (a major
indictable offence punishable by more than 10 years’ imprisonment)45 with the use
of any necessary violence, and that, while acting in furtherance of the aggravated
robbery, one of the parties to the JCE committed an intentional act of violence
which caused the deceased’s death.
62 Mr Howell’s case at trial was that he was not aware of the plan to rob the
grow house until they arrived at the house on Carousel Street. He argued that once
he became aware of such a plan, he objected to participating but ultimately
acquiesced when threatened by another member of the group. He relied upon a
defence of duress. Mr Howell argued that his role was confined to keeping a
lookout (under duress), while the others stole the cannabis and assaulted the
deceased.
63 It is not necessary to set out the evidence adduced at trial at length. As will
be apparent, the prosecution’s proposed grounds of appeal do not involve any
challenge to the judge’s findings of primary fact. They focus upon the judge’s
ultimate inferences or conclusions, and can be addressed largely by reference to
the operative passages from her Honour’s reasoning.
64 However, by way of overview, the prosecution case relied upon a substantial
body of evidence and agreed facts. This included:
• evidence from some friends of Mr Gjabri about his background (including
how he came to be living in the premises on Carousel Street, his car and the
discovery of his body on 12 October 2018);
• agreed facts linking Mr Rigney to possession of a white Holden commodore,
and Mr Mitchell to ownership of a blue Subaru, and establishing that the five
defendants travelled in these cars to Para Vista (arriving about 11.30pm on
45 Noting that it was contended that the theft of the cannabis with the use of force constituted robbery,
which was aggravated by reason of the offending being committed in company.

8 October 2018),46 and returned via Ingle Vale to Murray Bridge (arriving
about 1.30am on 9 October 2018);
• CCTV footage from various premises in the area of the Carousel Street grow
house showing two cars driving around the nearby streets shortly before
midnight on 8 October 2018, and then, shortly after midnight, five men47
walking towards, and entering, the Carousel Street premises;
• evidence from some residents of Gilbert Street, Ingle Vale, who saw the
defendants transferring the cannabis they had stolen from the Carousel Street
grow house;
• agreed facts and evidence in relation to the police searches and crime scene
investigation of the Carousel Street premises, including detail of the layout
of the premises, the cannabis set up, the damage to the premises, and various
items located throughout the premises;
• agreed facts and evidence in relation to the forensic testing (including
fingerprint and DNA analyses) carried out in relation to the Carousel Street
premises, various items located in those premises and Mr Gjabri’s car;
• evidence from a police officer with experience in investigating drug
offending as to various aspects of the operation of hydroponic cannabis set
ups such as the one found in the Carousel Street grow house; and
• evidence of various persons connected with Mr Howell (in particular, his then
partner, CD, and friends, TL and JL) as to their observations of, and
communications with, Mr Howell relevant to his involvement in the events
of the night of 8 October 2018, including describing his distress following
that night and on the occasions of subsequent media coverage of what had
occurred.
65 The evidence also included a record of Mr Howell’s police interview in
which he made various admissions as to his involvement in the events on the night
of 8 October 2018, whilst at the same time emphasising what he claimed were the
duress he was under and his limited involvement the robbery of the grow house.
Mr Howell described Mr Rigney as carrying a cricket bat as they approached the
grow house, and as using that bat to attack the Mr Gjabri. The prosecution
evidence also included some intercepted phone calls involving Mr Howell, and
some video files from his phone.
66 Finally, the prosecution also led evidence from a forensic pathologist,
Dr Charlwood. Dr Charlwood gave evidence relating both to the observations she
made of Mr Gjabri’s body when she attended the Carousel Street premises for that
46 Mr Howell, Mr Mitchell, Mr Carver and Mr Tenhoopen having travelled from Murray Bridge, and
Mr Rigney having travelled from Prospect.
47 Whom it was agreed were the five defendants.

purpose on 12 October 2018, and during the post-mortem examination that she
conducted a couple of days later. Dr Charlwood’s observations included: that
Mr Gjabri was 176 centimetres in height and 58 kilograms in weight; that he had
sustained injuries and bruising to over 20 locations on his body and head, as
indicated on a body chart she had prepared; that these injuries included an injury
to the top and left side of Mr Gjabri’s head comprising a v-shaped laceration up to
9.5 centimetres in length, as well as two other wounds on his head; that she was
not able to be precise as to the number of blows required to inflict the injuries as it
would depend upon the implement(s) used; that the injuries were consistent with
having been inflicted by a bat, including the edge of a cricket bat; and that she
could not usefully estimate the force with which the blows were struck. In
Dr Charlwood’s opinion, the cause of death was blunt force head injuries (applied
to the top and left of Mr Gjabri’s head), which she suggested were more likely to
have been the result of a moving object hitting his head than his head hitting a
stationary object. She estimated a time of death of between about 35 minutes and
24 hours after the fatal blow(s) were struck.
The judge’s findings of fact
67 After setting out a lengthy summary of the evidence adduced at trial, Stein J
proceeded to make detailed findings of fact. The key findings may be summarised
as follows.
68 As at October 2018, the Carousel Street house was set up as a cannabis grow
house, with Mr Gjabri residing there as a gardener. Three bedrooms of the house
were devoted to the hydroponic cultivation of cannabis, with two of those rooms
containing a number of mature plants. The cannabis taken by the defendants would
have been valuable.48
69 The windows of the Carousel Street house were intact and entry was not
gained via the windows. The state of the front door was consistent with entry into
the house through that door, which was achieved by the application of force and
without the use of tools.49
70 In the evening of 8 October 2018, four of the defendants (Mr Howell,
Mr Mitchell, Mr Tenhoopen and Mr Carver) drove from Murray Bridge to Para
Vista in a blue Subaru belonging to Mr Mitchell. They arrived and parked in Para
Vista at around 11.35am.50 A short time earlier, at about 11.15pm, Mr Rigney had
arrived in his white Commodore.51 Both vehicles were parked in a location a few
blocks from the Carousel Street grow house.

71 CCTV footage showed the five men approaching the Carousel Street grow
house on foot, albeit not by the most direct route from the location where they had
parked.52 As to the object carried by one of the men, the judge found:
[449] … the CCTV shows one man carrying a long linear object which, when held in the
hand of the walking man, reached close to the ground. The object reflected light
and, from its appearance, was consistent with being a cricket bat or a stick or pole.
Given the manner the object was held and its size, I infer the men would have been
aware that one of the group was carrying the object. The CCTV footage is too poor
to enable any findings about whether any of the men were carrying any other objects
in their hands or pockets.
72 The judge found that Mr Howell was aware that one of the defendants
(Mr Rigney) was in possession of a weapon, and that the weapon was a bat:
[503] Each of TL and JL referred to a cricket bat and CD thought Mr H possibly told her
about a bat. As set out above, given the CCTV footage, I consider it inherently
implausible that Mr H was not aware that someone in the group was carrying such
an object prior to the other men returning from the back of the house. Mr H referred
to Mr Rigney having a cricket bat in his record of interview. Although there was
inconsistency in his account of when he first saw the cricket bat, the alternative
accounts entailed his awareness of the bat prior to entering the house. I consider it
inherently unlikely that Mr H would make up a detail of a weapon in the nature of a
cricket bat if no weapon or no such weapon was being carried. The detail of a bat is
consistent with the CCTV showing a man carrying an object shaped like a bat. Based
on the record of interview, I find that Mr H knew prior to the group breaking in that
one of the men was in possession of a weapon and that weapon was a bat.
73 Shortly after midnight, the men walked down Carousel Street towards the
grow house in approximately single file.53 The men forced entry to the house
through the front door. Mr Howell and some of the other men covered their hands
before entering the house.54
74 The judge found that prior to entering the house, Mr Howell knew that there
was a person present in the house:
[501] During the record of interview, Mr H referred to a car in the driveway of the house
and to making noise going across the fence to warn the person they were coming.
Further, Mr H referred to expecting that they would go to the door, “punch” the man
and “steal a pound”, consistent with understanding someone was in the house. I
therefore find that prior to entering the house, Mr H knew that there was a person
present in the house.
75 Once inside, some of the men entered the bedrooms in which the mature
plants were growing in pots. They severed the plants at the stem, and placed the
stolen cannabis into black plastic bags.55 There was DNA evidence placing some
of the defendants in the house. Whilst there was no evidence placing Mr Howell

20
in the house, the judge found (based, inter alia, upon his record of interview) that
he entered the house.56
76 The judge found that, once inside, one or more of the defendants assaulted
Mr Gjabri:
[502] I accept Mr H’s account in his record of interview that Mr Gjabri was assaulted when
the men gained entry into the lounge room area of the house. I find that Mr Gjabri
was kept in the location of the lounge room by threats and use of force while the men
cut and removed the cannabis plants.
77 The judge also found that Mr Gjabri was a slight man, who was not
aggressive. She rejected as a reasonable possibility that he posed a threat to, or
attacked, any of the men. She accepted Mr Howell’s account (in his record of
interview) of Mr Gjabri attempting unsuccessfully to prevent the defendants
entering the kitchen where he was located, referring to Mr Rigney jamming the
door to that room open.57
78 The plastic bags containing the cannabis were placed in Mr Gjabri’s car,
which was in the driveway of the Carousel Street house. Based on the CCTV
footage, the men left in that vehicle at about 12.33am. They returned to their
parked vehicles, and then drove all three vehicles to Gilbert Street. In that location,
the men transferred cannabis bags from Mr Gjabri’s car to the boot of one of the
other cars. Mr Howell assisted in this task.58
79 The men then left Gilbert Street in their two vehicles and, after stopping at a
service station in Norwood, returned in convoy to Murray Bridge.59 There the men
divided the cannabis between them.
80 The judge accepted the evidence of Mr Howell’s partner, CD, that Mr Howell
arrived home with several plastic bags of cannabis. Her Honour accepted CD’s
description of Mr Howell as appearing white and distraught, and saying that he
was going to be sick.60 Her Honour also accepted the evidence of CD and
Mr Howell’s friends, TL and JL, about his adverse reaction to the subsequent press
coverage of what was described as a murder investigation. They had variously
described Mr Howell as white, crying and appearing frozen and scared following
a particular news report on 19 October 2018.61
81 The judge analysed in some detail the admissions that she was prepared to
find that Mr Howell made in his discussions with CD, TL and JL. Her Honour
accepted that each of these witnesses gave honest evidence to the best of their
recollection about conversations which had occurred about six years prior to them

giving evidence.62 She found that Mr Howell admitted to each of them that he went
to Adelaide to take part in a ‘drug rip’.63 She accepted that he claimed to have
expressed reluctance to take part, but nevertheless went with the other men.64
82 The judge accepted that Mr Howell admitted that some of the defendants
wore gloves; that they called out ‘police’ when entering the grow house; and that
his role involved keeping a lookout. These admissions were consistent with what
Mr Howell had subsequently said in his police interview.65
83 The judge accepted Mr Howell’s account in his record of interview that
Mr Gjabri was assaulted when the men gained entry into the lounge room area of
the house; and that Mr Grjabri was kept in the lounge room by threats and the use
of force while the men cut and removed the cannabis plants.66
84 The judge found that Mr Howell also admitted to CD, TL and JL that he had
hit Mr Gjabri with a bat or cricket bat, despite denying in his police interview that
he inflicted any blows. Her Honour also found that he referred to Mr Gjabri having
had his leg struck or broken with the bat.67 She accepted that Mr Howell admitted
seeing Mr Gjabri struck to the head, and blood flowing from his head, while
Mr Howell was present in the lounge room of the house (and hence prior to
Mr Howell leaving the house).68 Noting that the prosecution did not put its case
on the basis that Mr Howell was the assailant who struck Mr Gjabri on the head,
and indeed did not invite the judge to make any finding as to who was responsible
for that blow or blows, the judge said that she could not conclude beyond
reasonable doubt which injuries were inflicted by which individuals.69
85 As for causation, her Honour’s findings essentially reflected Dr Charlwood’s
evidence:
[425] I find that Mr Gjabri sustained blunt force trauma in the form of the injuries described
by Dr Charlwood.
[426] I accept Dr Charlwood’s evidence about the number of injuries sustained by Mr
Gjabri across his head and body … I find the bruising with linear areas in the
location of the chest and calf are consistent with a straight edged weapon.
[427] I accept Dr Charlwood’s evidence that the injuries to the top of Mr Gjabri’s head
were more likely to have been caused by a moving object hitting his head rather than
his head hitting a stationary object. I also accept the overlapping skull fracturing is
more suggestive of two blows but that one blow remains a possibility.

[428] I cannot determine precisely the number of blows inflicted on Mr Gjabri.
[429] I accept Dr Charlwood’s evidence and find that the injuries to Mr Gjabri’s leg, chest
and head were consistent with infliction by a cricket bat, but that those injuries could
have been caused by other objects, such as a heavy stick.
[430] I accept Dr Charlwood’s evidence and find that the force required to cause the scalp
fracture was severe force.
[431] I find that Mr Gjabri’s death was caused by blunt force injuries inflicted on the top
left side of Mr Gjabri’s head.
[432] I find that Mr Gjabri survived for a period of at least 35 minutes. I accept Brevet
Sergeant Buller’s evidence concerning the places in which blood was located. I infer
Mr Gjabri must have been conscious and moving around for at least part of the period
of time he survived and remained conscious, as evidenced by the blood on top of
cannabis leaf litter and the blood and vomit in locations including the bathroom.
[433] There was a smear of Mr Gjabri’s blood in the hallway near a light switch close to
the front door and on the door frame of the front door. … I am unable to make any
findings on this topic other than that Mr Gjabri must have been conscious and moved
to the location of the front door after the assault as evidenced by the blood stain in
that location. I accept Dr Charlwood’s evidence that he must have had some ability
to make decisions and sufficient strength to move around for some time after the
assault.
[434] Prosecution submitted that it was most likely that the head injuries were inflicted last
because such blows would have incapacitated Mr Gjabri and there would be no
reason to continue the assault and inflict the further injuries. Given Dr Charlwood’s
evidence about the period of likely survival and Mr Gjabri’s ability to move around
for a period of time after the assault and her inability to determine any sequence of
injuries, it is possible the head injuries could have been inflicted other than as the
last inflicted injuries. I cannot make any findings about the sequence in which the
various injuries were inflicted.
[435] I am unable to find how long Mr Gjabri survived beyond the period of 35 minutes
referred to by Dr Charlwood. I am unable to reach any conclusions about when Mr
Gjabri would have lapsed into unconsciousness.
86 Having made findings of fact, including the key findings set out above, the
judge set out her operative reasoning in relation to the charged offending.
The judge’s operative reasoning
87 The judge commenced her operative reasoning by addressing the prosecution
case on common law murder, before addressing constructive murder and then
manslaughter.
Common law murder
88 The judge commenced her analysis by describing the prosecution case on
common law murder pursuant to an EJCE:
-- 26 of 84 --
[2026] SASCA 71 S Doyle JA
23
[505] On the prosecution case, Mr H entered into an agreement with the other men to
commit robbery by breaking into the grow house occupied by Mr Gjabri to steal
cannabis using necessary force and, in the course of carrying out the plan, to which
Mr H was a party, Mr H foresaw the possibility one of the other men would commit
murder. The prosecution relied on the fact the group was armed and the way they
entered the house, contending it was in Mr H’s contemplation that Mr Rigney, who
had the bat and was a violent man, would kill the occupant in circumstances
amounting to murder.
An agreement to steal cannabis
89 The judge addressed whether Mr Howell entered into an agreement to steal
cannabis with the other defendants. In explaining her reasons for concluding that
Mr Howell had entered into such an agreement before entering the grow house,
and at the latest by the time the men were at the grow house, her Honour relied
upon several matters.70
90 The judge explained that it was inherently implausible that the men drove
from Murray Bridge to Para Vista and just coincidentally found themselves in the
vicinity of a grow house. The only credible explanation for their movement was
that it was intentional, with a purpose and target in mind. The way they parked
and then approached the grow house was inconsistent with any innocent
explanation. The only plausible reason to then break into the grow house was to
steal cannabis. This conclusion was supported by Mr Howell’s admission that he
took part in a ‘drug rip’. The judge added that, even if Mr Howell was not aware
of the purpose of the trip prior to, or during, the journey from Murray Bridge, by
the time he arrived at the Carousel Street grow house, and prior to entry into that
house, he was aware of the intention to steal cannabis from that house.
The scope of the agreement
91 The judge next addressed the scope of the agreement, and hence the agreed
JCE. As the judge observed, the prosecution case that the scope of the agreement
was not simply to steal cannabis, but also to use violence as necessary, was relevant
not only in establishing an agreement to commit the foundational offence of
aggravated robbery,71 but also in determining Mr Howell’s level of foresight.72 Her
Honour noted the prosecution reliance upon the men’s knowledge that there was
an occupant in the grow house who would need to be subdued, and that they went
in numbers and with a bat (which was a weapon not required for the theft, nor used
to enter the house).
92 The judge did not accept that what occurred was a well-planned operation,
given the public location and disorganised manner in which the men moved the
stolen cannabis from Mr Gjabri’s car into their own cars. At the same time, it was
not a coincidental happening upon the grow house. There was sufficient planning
to result in five men in two separate cars congregating in the vicinity of the

24
Carousel Street grow house late at night, and then proceeding by foot with a bat
and using force to enter the premises with the intention of stealing the cannabis
located inside.73 As the judge observed, the success of the plan would depend in
part on preventing any person who may be present from impeding the plan. In
those circumstances, her Honour found that it was inherently implausible that the
plan did not include the potential for a threat or application of force in order to
subdue the occupant or otherwise deter him from interfering with the success of
the plan:
[514] … It is thus inherently implausible that no consideration was given to the potential
for the grow house to be occupied and what steps would be taken if that eventuality
transpired in order to ensure the operation was successful. I consider it fanciful that
the agreement did not contemplate the potential need to take steps to prevent an
occupant from impeding the planned theft. The carrying of the bat was consistent
with such contemplation. I thus consider it inherently implausible that the agreement
did not contemplate the need to use the bat to threaten or strike the occupant to
subdue him or deter him from interfering in the operation to ensure the success of
the plan. Put differently, I do not consider it a reasonable possibility that the plan to
steal did not include the potential for threat or the application of force by way of
assault against an occupant.
93 However, the judge added that this conclusion did not necessarily entail an
agreement the scope of which contemplated the use of any level of violence.74 The
judge noted her earlier findings that Mr Howell knew that the grow house was
occupied, and that Mr Rigney was carrying a bat as they entered. She noted that
the bat was neither tailored to, nor used for, the purpose of gaining entry; but that
it was an item that could be used ‘to threaten and to inflict injury to subdue’. Her
Honour inferred that the bat was carried ‘with the intended purpose of use in
deterring the occupant of the grow house from preventing the planned theft.’75
94 The judge summarised her earlier findings about the circumstances of the
men’s entry to the grow house:
[518] At least by the time the men entered the grow house, they were in fact aware there
was an occupant in the house. The combination of the vehicle parked in the
driveway, yelling “police” on entry through the front door, Mr H’s account of
Mr Rigney entering the house with the bat, moving to the kitchen door where
Mr Gjabri was peering through the door, and Mr Rigney forcing his way through
supports an inference that the men were aware of an occupant and took steps
immediately to prevent the occupant impeding their entry and theft of the cannabis.
Mr H acknowledged knowing there was an occupant and referred to his asserted
understanding that they would punch the man in the nose and take his cannabis. This
is consistent with Mr H knowing there was someone present and anticipating the use
of some level of force to enable the successful theft of the cannabis.
95 Her Honour considered this provided a sufficient basis to find that there was
‘at least tacit agreement to the participants taking steps including threats and use

74 Reasons [515].
75 Reasons [516].
-- 28 of 84 --
[2026] SASCA 71 S Doyle JA
25
of force to subdue the occupant while the theft took place to ensure a successful
operation’.76
96 In her Honour’s view, the evidence did not permit her to infer an agreement
to use any level of violence, including the infliction of lethal or fatal force.
However, it was sufficient to establish an agreement to use ‘some force to assault
and subdue the occupant to ensure the success of the plan to steal the cannabis’:
[521] If the men had been armed with knives or guns, it would provide a basis for a stronger
inference to the effect that any level of violence, including lethal force, was part of
the agreement. However, entry into the house with a bat does not justify the same
strength of inference. If the scope of the agreement had been to cause grievous
bodily harm or kill the occupant, it would be expected that the participants would
have entered the house armed with suitable weapons apt to achieve that eventuality,
such as guns or bladed weapons.
[522] There is insufficient evidence to satisfy me beyond reasonable doubt that the scope
of the agreement must have included any form of violence including infliction of
fatal force. However, taking into account the matters to which I have referred above,
I am satisfied beyond reasonable doubt that the scope of the agreement included
threats or the use of some force to assault and subdue the occupant to ensure the
success of the plan to steal the cannabis.
97 As the scope of the agreement did not extend to the violence inflicted upon
Mr Gjabri (that is, violence perpetrated with an intention to kill or cause grievous
bodily harm), the prosecution case for common law murder was predicated upon
an application of the principles of EJCE. However, before addressing the
application of these principles, the judge first addressed Mr Howell’s participation
in the agreement that she found was established.
Participation in the enterprise
98 The judge rejected the submission that Mr Howell was present in the house
but did not participate. He participated by donning gloves, entering the house,
acting as a lookout and taking some part in the assault of Mr Gjabri.77 On her
Honour’s reasoning, this was so, even if he had not expected the significant level
of violence which was inflicted upon Mr Gjabri, and even if he had told others to
leave Mr Gjabri alone prior to leaving the house. Any change of heart was not
sufficient to constitute an effective withdrawal from the enterprise.78 Given
Mr Howell’s admission that he saw blood streaming down Mr Gjabri’s face, the
judge considered it implausible that there was a single causative blow to
Mr Gjabri’s head after he had left the house.79 Further, and in any event, even if
Mr Tenhoopen had remained in the house after Mr Howell left, the cannabis was

26
still being loaded into the car in the driveway at this time (meaning, it would seem,
that the joint enterprise was still on foot).80
EJCE and the foresight of murder
99 The judge correctly observed that, in order for Mr Howell to be guilty of
murder by EJCE, the prosecution was required to prove beyond reasonable doubt
that Mr Howell foresaw (as opposed to agreed) that in carrying out the joint
enterprise to break into the house and steal cannabis, one or more of the
participants might cause death or grievous bodily harm to the occupant
accompanied with the intention to kill or cause grievous bodily harm.81
100 The judge reiterated her finding that the act or acts of striking Mr Gjabri to
his head were a substantial cause of his death. Her Honour was also satisfied that
the act or acts were voluntary and deliberate, and were not attended by any lawful
excuse.82
101 However, her Honour was not satisfied that the prosecution established
beyond reasonable doubt that Mr Howell foresaw that, in the course of the joint
enterprise, one of the defendants might cause grievous bodily harm or death with
murderous intent:
[532] As set out above, on Mr H’s own account, Mr H knew the house was occupied and
Mr Rigney was carrying the cricket bat when they entered the house. It is inherently
implausible that Mr H could not have foreseen that the bat might be employed in
some way to threaten or strike the occupant to deter him from interfering in the theft.
However, a bat is capable of being used to threaten or to strike a person’s legs or
arms or trunk sufficient to cause pain in order deter the person from attacking
invaders or taking steps to thwart a theft without inflicting grievous bodily harm or
death. A strike or strikes sufficient to cause grievous bodily harm or kill is not
required to achieve that end, nor is that level of injury necessarily inherent in use of
a weapon of that nature. Mr H’s reference to punching the man to steal a pound in
the record of interview is consistent with foresight or an expectation of the possibility
of some form of assault on the occupant of the grow house. However, the evidence
as a whole is insufficient to satisfy me beyond reasonable doubt that Mr H foresaw
that one of the men might attack the occupant causing grievous bodily harm or death
with the requisite intention to inflict grievous bodily harm or to kill. There is no
evidence the men entered with more than the cricket bat or with weapons of a kind
intrinsically likely to cause serious injury or death, such as knives or guns. There
was no use of such a weapon, despite the discovery of the knife with Mr Carver’s
DNA. There is no evidence that other items found in the house, such as the hammer
and crowbar depicted in the crime scene photographs, were employed as weapons
against Mr Gjabri.
[533] The extent of Mr H’s distress on his return to Murray Bridge and in Kadina is not
consistent with that of a man who had taken part in an operation which ran as
planned. At the time Mr H returned to Murray Bridge he did not know Mr Gjabri
had died. While I cannot find precisely what caused his reaction on his return, it is

27
reasonably possible that his significant distress was a result of the extent of the
assault on Mr Gjabri and incompatible with Mr H possessing foresight that one of
the group may assault Mr Gjabri with the intention of causing grievous bodily harm
or death.
[534] I therefore cannot find beyond reasonable doubt that in the course of participating in
the joint enterprise, Mr H foresaw that one of his co-accused might cause grievous
bodily harm or death with murderous intent.
Conclusion on common law murder
102 Although the judge held that the prosecution had excluded duress,83 because
it had not proved the requisite foresight on the part of Mr Howell, it failed to
establish its case against him for common law murder based on ECJE.84
Constructive murder
103 In commencing her analysis of constructive murder pursuant to a JCE, the
judge explained that the prosecution case for constructive murder required that
Mr Howell was party to an agreement to commit a foundational offence, being the
major indictable offence of aggravated robbery, ‘including the use of any
necessary force’.85
104 The judge noted that the foundational offence of robbery, aggravated by it
being committed in company, was a major indictable offence with a maximum
penalty of more than 10 years’ imprisonment. Drawing on the findings referred to
earlier in these reasons, the judge was satisfied that all of the elements of this
foundational offence were committed by the participants in the joint enterprise,
and that Mr Howell was party to the agreement to commit that offence, and
participated in the joint enterprise by which it was committed.86
105 The judge next noted her conclusion that the intentional act or acts of
violence that caused Mr Gjabri’s death were committed during the course of the
aggravated robbery.87
106 However, as her Honour explained, for Mr Howell to be guilty of
constructive murder pursuant to a JCE, the scope of the parties’ agreement was
required to include ‘the possible commission of an intentional act of violence of
the same general nature as that which caused Mr Gjabri’s death’.88
107 Drawing upon similar reasoning to that which she applied in concluding that
Mr Howell did not have the foresight necessary to establish common law murder
pursuant to an EJCE, the judge was not satisfied that Mr Howell was party to an

28
agreement which included the possible commission of an intentional act of
violence of the same general nature as that which caused Mr Gjabri’s death:
[558] While the issue of the scope of the agreement and questions of foresight are distinct,
there is an overlap of the relevant evidence from which inferences may be drawn
concerning each.
[559] I am not satisfied beyond reasonable doubt that the possession of the bat prior to
entry into the grow house is consistent only with an inference that the agreement
included the possibility of violence of same general nature as caused the death.
In this case, the violence that caused the death was striking the occupant of the grow
house to the head with the weapon with sufficient force to fracture the skull resulting
in the consequential brain injuries. The evidence is not sufficient to satisfy me
beyond reasonable doubt that violence of the same general nature as caused death
was within the scope of the joint enterprise. As discussed above, a bat is capable of
being used to subdue without necessarily striking to the head or necessarily causing
grievous bodily injury or death. The position may have been different if the men
had entered the house with guns or knives.
[560] Further, while Mr H’s reference to punching the man to steal a pound in the record
of interview is consistent with foresight or expectation of the possibility of some
form of assault on the occupant of the grow house, that is of a very different nature
to the violence inflicted by striking Mr Gjabri to his head with the bat and with
sufficient force to fracture his skull.
108 The trial judge concluded that the prosecution had failed to prove its case for
constructive murder based on JCE.89
Manslaughter
109 Having concluded that common law murder by EJCE and constructive
murder by JCE had not been made out, that left for consideration manslaughter by
EJCE.90
110 As the judge explained, a finding of manslaughter by unlawful and dangerous
act required proof that a reasonable person in the position of the assailant would
have realised he was exposing Mr Gjabri to an appreciable risk of serious injury
when striking him to the head with the bat. The judge found that the blow or blows
which caused the death of Mr Gjabri was or were dangerous; that a reasonable
person in the position of a person striking Mr Gjabri to the head with a bat would
have realised that this would expose him to an appreciable risk of serious injury.91
111 The judge was satisfied that Mr Howell was party to, and participated in, a
joint criminal enterprise to steal cannabis and use threats or force to subdue the
occupant of the grow house; and that he foresaw the possibility that the bat might
be used to subdue the occupant causing serious injury to the occupant:

29
[565] Mr H entered into and participated in a joint criminal enterprise to steal cannabis.
The scope of the agreement included use of threats or force to subdue the occupant
to ensure the success of the plan to steal the cannabis.
[566] Without repeating all of the matters to which I have referred above, Mr H knew the
members of the group were intending to steal cannabis from a grow house, knew
there was a person in the grow house and knew that one of the men was armed with
a bat. A bat is not a weapon necessarily likely to inflict injury sufficient to cause
grievous bodily harm or death. Nevertheless, a bat by its very nature is of a size and
weight sufficient to be inherently capable of causing serious injury if wielded against
a person. I reject as fanciful the possibility that Mr H did not foresee the possibility
the bat might be used to subdue the occupant causing serious injury to the occupant.
112 The judge concluded that Mr Howell was therefore guilty of manslaughter
by operation of the principles of EJCE.92
Summary
113 It is useful to conclude this summary of the judge’s operative reasoning by
summarising her Honour’s carefully calibrated conclusions as to the nature and
level of the violence that Mr Howell agreed to, or foresaw, as a possible incident
of the joint enterprise to steal cannabis from the Carousel Street grow house.
114 In describing the scope of the agreement, the judge rejected the argument that
Mr Howell was party to an agreement to steal cannabis that included the possible
use of any level of violence.93 However, her Honour accepted that the scope of the
agreement included the possible use of the bat to threaten or apply force to
(including strike and cause injury to) the occupant in order to subdue him or deter
him from interfering with the plan to steal.94
115 In rejecting the prosecution case of common law murder pursuant to an
EJCE, the judge was not satisfied that Mr Howell foresaw that, in the course of the
joint enterprise, one of the defendants might cause grievous bodily harm or death
with murderous intent.95
116 Further, in rejecting the prosecution case of constructive murder pursuant to
a JCE, the judge was not satisfied that Mr Howell agreed to the possibility of
violence of the same general nature as that which occurred; that is, the possibility
of the use of the bat to strike the occupant to the head with sufficient force to
fracture his skull (as opposed to using it to subdue the occupant without striking
him to the head with this force or otherwise inflicting grievous bodily harm or
death).96

117 However, in accepting the prosecution case of manslaughter pursuant to an
EJCE, the judge was satisfied that Mr Howell foresaw the possibility that the bat
might be used to subdue the occupant in a manner causing serious injury to him.97
The Director’s appeal
118 The Director of Public Prosecutions seeks permission to appeal on three
grounds.
119 Ground 1 involves a contention that the judge erred in failing to determine
whether, or hold that, the scope of the agreement or joint enterprise to which the
appellant was party encompassed the authorisation of whatever force was
necessary to effect the foundational offence of aggravated robbery.
120 Ground 2 involves a contention that the judge erred in holding that the scope
of the agreement or joint enterprise to which the appellant was party did not
encompass the possible commission of an intentional act of violence of the same
general nature as the act(s) which caused death.
121 Ground 3 involves a contention, in the alternative to Grounds 1 and 2, that
the judge’s reasons in respect of these matters were inadequate.
122 Under s 157(1)(b)(i) of the Criminal Procedure Act 1921 (SA), the Director
may, with the permission of the Court, appeal ‘on any ground’ against an acquittal
entered following a trial by judge alone.
123 The principles governing an appeal, and application for permission to appeal,
under this section have been considered in several decisions of this Court,
including R v Fitzgerald,98 R v Donovan99 and Allison (a pseudonym) v The King.100
It has been accepted that the appeal is by way of rehearing, albeit acknowledging
the protean nature of this label, and that there remains some uncertainty about the
precise nature and scope of the contemplated rehearing. Ordinarily, an appeal by
way of rehearing involves a focus upon identifying error in the decision below.
However, it usually requires that the appellate court undertake an independent
review of not only any issues of law, but also the facts, including the proper
inferences to be drawn from the evidence. The appropriateness of this broad
approach to the identification of error is supported in the present context by the
specification that the appeal may be ‘on any ground’.
124 At the same time, it has also been accepted that the public interest concern to
avoid exposing defendants to double jeopardy will inform the Court’s approach to
its jurisdiction under s 157(1)(b)(i). The appellate restraint which this concern
requires has a role both in determining whether there should be a grant of
97 Reasons [566].

31
permission to appeal, and in determining the relief, if any, which might be granted
upon the identification of error.
125 With this framework in mind, the statement of principles in R v Fitzgerald101
should be understood as providing guidance, rather than any rigid rules, as to the
Court’s exercise of its jurisdiction in relation to appeals against acquittals under
s 157(1)(b)(i). In particular, whilst the Court may more readily intervene in the
case of an error of law, or an error of general principle, the court’s intervention is
not confined to cases involving errors of this type. In an appropriate case, other
errors, such as errors in the application of principle to the facts, in the inferences
to be drawn from facts, or indeed in the findings of fact, may warrant the Court’s
intervention. While the Court will not ordinarily, or lightly, intervene so as to
address issues of fact, whether permission is granted, and whether the Court grants
the relief sought, will depend upon the nature and consequences of the error, and
the circumstances of the case more generally.
126 The Director’s proposed grounds of appeal raise some significant issues of
principle in relation to the operation of the doctrines of JCE and EJCE in the
context of a charge of murder, in particular where the case involves an allegation
of constructive murder. As will be seen, the Director’s proposed appeal raises for
consideration the rationale for, and content and application of, the requirement, in
a case alleging constructive murder pursuant to a JCE, that the agreement
encompass violence of ‘the same general nature’ as that which caused death. The
grounds sought to be raised are reasonably arguable. In my view, the issues sought
to be raised are of sufficient substance and significance to warrant this Court’s
consideration, and the present case is an appropriate vehicle for them to be
considered. I am satisfied that the public interest in this Court’s consideration of
the grounds sought to be raised outweighs the concern to avoid exposing
Mr Howell to a risk that his acquittal might be set aside. Whilst this concern to
avoid further vexing an accused person is undoubtedly a weighty matter in the case
of a prosecution appeal against an acquittal – particularly in the present case where
a successful appeal would result in Mr Howell being tried for a third time – it is
outweighed in the circumstances of the present case by the public interest in
addressing the issues sought to be raised by the Director.
127 For these reasons, I would grant the Director permission to appeal. However,
whether that appeal is ultimately to be allowed may depend upon the nature of any
error that might ultimately be identified.
The scope of the agreement – violence of ‘the same general nature’
128 Grounds 1 and 2 are related in that both challenge, in slightly different ways,
the judge’s conclusions as to the scope of the agreement or JCE in which she found
that Mr Howell participated. They both focus upon the scope of the agreement or

JCE in the context of the prosecution’s second pathway to guilt of murder, namely
through constructive murder and applying the principles of JCE.
129 As set out above, the judge found that the scope of the agreement included
the possible use of the bat to threaten or apply force to (including strike and cause
injury to) the occupant in order to subdue him or deter him from interfering with
the plan to steal.102 However, the judge found that the second pathway to guilt of
murder was not made out because the agreement or JCE did not include the
possibility of violence of ‘the same general nature’ as that which occurred; that is,
the possibility of the use of the bat to strike the occupant to the head with sufficient
force to fracture his skull (as opposed to using it to subdue the occupant without
striking him to the head with this force or otherwise inflicting grievous bodily harm
or death).103
130 Ground 1 challenges the judge’s approach on the basis that she did not
grapple with, or at least erroneously rejected, the prosecution case that the
agreement was to use any, or whatever, force was necessary to achieve the plan to
steal cannabis from the grow house. As such, the force used was within the scope
of the agreement.
131 Ground 2 challenges the judge’s rejection of the prosecution argument that
the scope of the agreement included the possibility of violence of the same general
nature of that which occurred. In particular, the Director argues that the judge
erred in this respect in drawing a distinction between: (i) violence for the purpose
of subduing the occupant of the grow house (but including striking him with a bat
and a risk of serious injury); and (ii) violence involving aggressively striking the
occupant to the head with sufficient force to fracture his skull.
132 In developing his submissions in support of these grounds, the Director did
not challenge any of the judge’s primary findings of fact. His submissions were
focussed upon a challenge to the ultimate inferences drawn, and conclusions
reached, by the judge. Further, as developed orally, the Director’s submissions
very much focussed upon the issues raised by Ground 2.
133 In addressing the Director’s submissions, it is convenient to commence with
the High Court’s reference, in the context of applying the principles of JCE to
constructive murder, to a requirement that the scope of the agreement include the
possible commission of an intentional act of violence of the ‘same general nature’
as that which occurred.
134 As outlined earlier in these reasons, in Mitchell, Gordon, Edelman and
Steward JJ referred to this requirement in paragraphs [65] and [108] of their joint
reasons;104 and Gageler, Gleeson and Jagot JJ did so in paragraph [48] of their joint
102 Reasons [514], [516].
103 Reasons [559]-[560].
104 Their Honours also used this terminology in paragraph [58], in the analogous context of the foresight
necessary to establish liability through the principles of EJCE.

33
reasons, expressly adopted this expression of what was required to establish
constructive murder applying the principles of JCE.
135 In my view, the High Court’s reference to violence of the ‘same general
nature’ should not be understood as the introduction of a new element or
requirement over and above the general principles governing constructive murder
and JCE set out earlier in these reasons. Rather, their Honours were merely
articulating what was inherent in the requirement that the scope of the agreement
encompass the possibility of the act or acts constituting the crime which was
committed, and with which the defendant has been charged.
136 This emerges most clearly from paragraph [65] of the reasons of Gordon,
Edelman and Steward JJ. In that paragraph, their Honours were addressing the
requirement, for the purposes of attributing criminal acts to a defendant pursuant
to a JCE, that the act be within the scope of the agreement. In explaining what this
entailed, their Honours said that the agreement ‘need not extend to the precise
manner in which the act was committed’. Rather, it was ‘sufficient for the scope
of the agreement to extend to acts of the general nature of the attributed act’. In
other words, the requisite correspondence or correlation between the agreement
and the act to be attributed need not be precise or specific; it need only be general.
137 Gordon, Edelman and Steward JJ illustrated this point by reference the
decision of the English Court of Criminal Appeal in R v Betts.105 In that case, Betts
and Ridley knew that the deceased was in the habit of taking money in a bag to the
bank and, knowing the route which he took to the bank, agreed they would waylay
him and rob him. Pursuant to their agreement, they hired a car and drove to the
location where the deceased would pass. Ridley waited in the car while Betts
robbed the man of the bag of money that he was carrying. In so doing, Betts seized
the man by the neck and struck him a violent blow on the top of his head with a
clenched fist, and most likely with a weapon or implement of some kind concealed
within his fist. The man suffered a depressed skull bone, and died. On appeal,
Ridley challenged his conviction as a principal in the second degree. He did so on
the basis that, although he had agreed that the man should be robbed, and had
agreed or anticipated that the man would, at least, be pushed down when the bag
of money was snatched from him, he was not a party to an agreement that violence
of any kind should be used.106 In rejecting this argument, the Court held that even
though Ridley had not agreed that the man would be struck on the head in a way
likely to cause his death, he was nevertheless liable for what occurred. Their
Honours drew a distinction between a situation in which the principal acts in a way
which varies ‘totally and substantially’ from what had been agreed, and a situation
where the only variance is ‘in the circumstance of time or place, or in the manner
of execution’. In their Honours’ view, Ridley was in the latter situation, and thus
properly convicted of felony murder. Even though Betts’ conduct ‘did vary in the
manner of execution of this agreed plan to rob’, it was sufficient in the
105 R v Betts (1930) 22 Cr App R 148.
106 R v Betts (1930) 22 Cr App R 148 at 151-152, 154 (Avory, Swift and Charles JJ).

34
circumstances of that case that there was a plan to rob ‘with some degree of
violence’.107
138 Gordon, Edelman and Steward JJ also footnoted several other cases on the
same issue. It is to be acknowledged that some of those cases include support for
agreements to commit a robbery or other felony described in terms which
encompassed the commission of any act of violence which might become
necessary for the furtherance or completion of that purpose.108 At the same time,
and whilst admittedly approaching the issue at a relatively high level of generality,
those same cases acknowledge that there are limits to what it may be inferred was
within the scope of the parties’ agreement. Liability will not extend, for example,
to acts which are ‘quite foreign’ to,109 or otherwise beyond,110 the agreed purpose.
In other words, it is not necessarily enough that the agreement contemplated some
use of violence. Questions of fact and degree inevitably enter the equation when
determining whether the act of violence that occurred was a possibility
encompassed within the agreement.
139 In support of this, it is noteworthy that earlier in their reasons, when using
the same terminology of acts of ‘the general nature’ of what occurred (albeit in the
context of a consideration of what the defendant foresaw, as opposed to agreed),
Gordon, Edelman and Steward JJ cited passages from academic works by
Glanville Williams and E Patrick Hartt.111
140 In his text, Williams considered the decision in R v Betts. After observing
that the Court in that case concluded that what Betts did was merely a variation in
the manner of execution of the agreed plan to rob, he posed the question whether
it would have made a difference had Betts chosen to use a knife or a revolver.
Whilst acknowledging that there may not be a substantial difference between using
a knife and hitting a man on the head with a weapon, Williams considered that
Ridley would not have been liable because the act would have been ‘altogether
outside the common purpose’.
141 Williams went on to consider two hypothetical variants of the facts in R v
Appleby,112 concluding that liability would not extend to circumstances where the
violence used was ‘altogether different in kind from that agreed’:
Appleby and his companion were housebreakers who agreed to resist arrest by violence;
the companion used a gun, with fatal results, and Appleby was held to be implicated in the
107 R v Betts (1930) 22 Cr App R 148 at 154-155 (Avory, Swift and Charles JJ).
108 For example, R v Dowdle (1900) 26 VLR 637 at 639-640 (Williams J); R v Kalinowski (1930) 31
SR(NSW) 377 at 380 (Davidson, Halse Rogers and Stephen JJ).
109 R v Kalinowski (1930) 31 SR(NSW) 377 at 380 (Davidson, Halse Rogers and Stephen JJ) (referring to
a sexual act in the course of a robbery).
110 R v Dowdle (1900) 26 VLR 637 at 640 (Williams J) (referring to a ‘violent shove into a yard’ in the
context of a plan merely to ‘hustle’ a drunk man and pick his pockets).

murder. … The question can perhaps be clarified by taking two hypothetical cases. (1)
Suppose that Appleby and his companion had agreed that if surprised by a watchman they
would overpower him with their hands and tie him up. This would have been an intent to
resist arrest by violence, and it if had been carried out and the watchman had accidentally
been killed, both might have been guilty of murder. (2) Suppose that, with the agreement
as before, Appleby’s companion had used a gun which Appleby did not know he was
carrying. It is submitted that that would have been an act outside the common purpose, for
which Appleby would not have been responsible. Notwithstanding the language of the
judgment, an agreement to use violence does not implicate the principal in the second
degree if the violence used is altogether different in kind from that agreed.
142 Hartt made observations to similar effect. After referring to R v Betts, where
liability attached to Ridley despite Betts using a greater degree of violence than
had been agreed, Hartt suggested that where limited violence had been agreed, the
introduction of a weapon from which death results might be outside the scope of
the agreement with the result that liability does not attach. Hartt added that ‘the
whole matter’ had been dealt with in the passage from Williams’ text referred to
above.
143 In my view, the approach taken by the High Court in Arulthilakan v The
Queen113 is consistent with the above. That case involved the application of the
principles of JCE to constructive murder under s 12A of the CLCA. The co-
accused of the two appellants stabbed and killed a person in the course of a
robbery. However, both appellants were party to an agreement to ‘roll’ the
deceased, and were aware that their co-accused was in possession of the knife
which was used. Indeed, as the Court explained, they were plainly anticipating
violence:114
The plan upon which the appellants and [their co-accused] embarked upon was to ‘roll’
Hillam in order to obtain his mobile telephone. That involved robbery, accompanied, if
necessary, by force. Perhaps there was a theoretical possibility that Hillam would hand
over the telephone without resistance, but the three intending robbers had, between them,
two knives and a cosh. They were not intending to rely on their powers of verbal
persuasion. They had equipped themselves to deal with resistance. The appellants knew
[their co-accused] was armed. It was not difficult to infer why he was armed.
144 In referring back to this case in Mitchell, Kiefel CJ explained that liability
attached because the plan ‘involved robbery accompanied if necessary by force
and the use of force was therefore within the scope of the agreement’.115 In
circumstances where there was no real issue that the violence that did occur was a
possibility within the scope of the agreement, there is no difficulty with the
agreement being formulated in these terms. There was no occasion or need to
consider whether the violence that occurred fell outside the type or nature of the
violence that had been agreed as a possibility. However, I do not understand the
decision in Aruthilakan v The Queen, or Kiefel CJ’s reference to it in Mitchell, to
suggest that it may not be necessary in other cases to focus more closely upon the
113 Arulthilakan v The Queen (2003) 78 ALJR 257.

36
correlation between the nature of the possible violence that had been agreed, and
the violence that was used and caused death.
145 It is appropriate at this point to mention the decision of Wright J in R v DJD116
in relation to the application of the doctrine of JCE to constructive murder under
s 18(1)(a) of the Crimes Act 1900 (NSW). In addressing the need for the scope of
the agreement to encompass the possibility of the act of violence which caused
death, his Honour said:117
The degree of specificity required in respect of the accused’s agreement as to the possible
use of violence will depend on the circumstances of each individual case. Nonetheless,
where an offence may be accompanied by some form of violence and the participants in a
joint criminal enterprise to commit that offence have no reason to be specific about the
particular form of violence, in my view there does not have to be agreement to the specific
type of violent act actually done before that act can be attributed to other participants in the
joint criminal enterprise. For example, if the parties to an assault with intent to rob in
company armed with a dangerous weapon agree to the use of force or violence
accompanying the commission of that offence, if necessary, then for the purposes of
attribution of an act of one of the participants to the other, it should not matter whether the
violence actually used was by way of shooting, wounding with a knife or screwdriver,
hitting with a heavy vase found at the scene, or bashing the deceased. In such a case, it is
the possible use of force or violence generally not the particular type of violence which was
agreed to and which gives rise to the attribution of the acts to the participants who agreed.
This conclusion is consistent with the comments and examples referred to by the High
Court in Mitchell. These include what was noted by Kiefel CJ when discussing the
application of the doctrine of joint criminal enterprise in the context of s 12A of the South
Australian Criminal Law Consolidation Act. …
146 Wright J proceeded to refer to the High Court’s reasons in Mitchell, quoting
from both the reasons of Kiefel CJ addressing Aruthilakan v The Queen,118 and the
passage from the joint reasons of Gordon, Edelman and Steward JJ in which their
Honours said that the agreement must include the possible commission of an
intentional act of violence of ‘the same general nature’ as that which caused the
death.119 Wright J then added:120
The additional element referred to by the three justices as being agreement to ‘the possible
commission of an intentional act of violence of the same general nature as that which
caused the death’ reflects, in part, the wording of s 12A which requires that the death be
caused by an ‘intentional act of violence’. Nonetheless, the formulation adopted also
indicates that the agreement required does not have to be to the specific act of violence
which actually occurred.
For all of these reasons, in the context of s 18(1)(a) of the Crimes Act and in the
circumstances of this case, in order for the act of the participant who stabbed Mr Kourtis

37
to be attributed to each of the accused, the Crown is required to prove beyond reasonable
doubt that the accused was a participant in the joint criminal enterprise to commit the
foundational offence and also agreed that the foundational offence would, if necessary, be
accompanied by force or violence. The Crown does not have to prove that each accused
agreed specifically to the possible use of a knife or to the possible wounding of the deceased
accompanying the commission of the foundational offence.
147 The Director relies upon these passages from Wright J’s reasons as
supporting the approach contended for by the prosecution in the present matter. In
particular, he contends that they support an approach which accepts that if the
defendant agreed that the foundational offence would, if necessary, be
accompanied by force or violence, then that would be enough to bring the act of
violence which occurred within the scope of the agreement for the purposes of
establishing liability for murder.
148 The first difficulty with the Director’s reliance upon Wright J’s reasons in
R v DJD is that his Honour’s analysis was overruled by the New South Wales
Court of Criminal Appeal in Coskun v R.121 That said, as the reason for overruling
it was that it involved an attempt to apply the reasoning of the High Court in
Mitchell without adequate regard to the differences between the constructive
murder provision in s 18(1)(a) of the Crimes Act and the common law and South
Australian provision under consideration in Mitchell, his Honour’s observations
may still carry some persuasive value in this jurisdiction.
149 More fundamentally, however, I do not agree that Wright J’s reasons support
the Director’s approach. In my view, Wright J said nothing more than that in some
cases it will be appropriate to approach the matter at this level of generality. As
has been explained, it was appropriate to approach the matter at this level of
generality in Arulthilakan v The Queen. However, as Wright J explained in the
opening sentence of the first passage extracted from his reasons, the degree of
specificity required will depend on the circumstances of each individual case.
Whilst accepting that it will not ordinarily be necessary that the agreement
encompass the possibility of ‘the particular type of violence’ used, or ‘the specific
act of violence’ which occurred, nothing his Honour said was inconsistent with a
requirement that the agreement encompass the possibility of violence of the ‘same
general nature’ as that which occurred. To the contrary, his Honour,
unsurprisingly, embraced this formulation through his reference to the reasons of
Gordon, Edelman and Steward JJ from Mitchell.
150 Understood in this way, Wright J’s reasons leave open the possibility of
circumstances which might, in an appropriate case, justify a conclusion that an
agreement that encompasses the use of some violence does not extend to the
possibility of violence of the same general nature as that which occurred.

151 Against this background, it is appropriate to turn to whether the
circumstances of the present matter justified Stein J’s adoption of such an
approach.
152 The operative sections of Stein J’s reasons have been summarised earlier in
these reasons. Critically, her Honour drew a distinction between: (i) violence for
the purpose of subduing the occupant of the grow house (but including striking
him with a bat and a risk of serious injury); and (ii) violence involving aggressively
striking the occupant to the head with sufficient force to fracture his skull. In her
Honour’s view, although the agreement between the parties encompassed a
possibility of the former, it did not encompass a possibility of the latter.
153 It is apparent that there were two aspects to her Honour’s distinction between
the violence that was agreed and the violence that occurred. The first was
grounded in the purpose of the violence, with the agreed purpose being violence
to subdue. Her Honour drew a distinction between violence for this purpose, and
the violence that occurred, being more aggressive, if not gratuitous, in its purpose.
The second was grounded in the degree or severity of the violence, with the agreed
violence extending to striking with a risk of serious injury, and the violence that
occurred involving striking to the head with sufficient force to fracture the victim’s
skull.
154 In addressing the second aspect of the distinction drawn by Stein J, it is true
that her Honour at times made reference to the consequence of the violence
(referring to the violence being sufficient ‘to fracture the victim’s skull’, and to it
being ‘fatal’ or ‘lethal’). Properly understood, however, the focus of the second
aspect of her Honour’s distinction was upon the degree of severity of the violence
inflicted rather than the consequences. Her Honour’s references to the potential
consequences of the violence, or risks associated with the violence, were by way
of elaboration upon the degree or severity of the violence, rather than suggesting a
focus upon the consequence of the violence per se. Her Honour was right to focus
upon the degree or severity of the violence, rather than the consequences of that
violence, given that the issue is whether the violence that occurred, and not the
consequence that occurred, was of the same general type as that which was agreed.
155 In my view, there is no conceptual difficulty with either aspect of the
distinction drawn by her Honour. Both a difference in the purpose of the violence,
and a difference in the degree or severity of the violence, may, in an appropriate
case, constitute a difference in the ‘general nature’ of the violence. They may do
so individually, and certainly may do so in combination. In other words, where an
agreement is confined to the possible use of low level violence in order to subdue
a person, the occurrence of high level violence which goes well beyond what might
be necessary to subdue that person may, depending upon the circumstances of the
particular case, aptly be described as violence which is not of the ‘same general
nature’ as that which had been agreed as a possibility. Put in positive terms, it may
aptly be described as violence which falls outside the scope of the agreement
-- 42 of 84 --
[2026] SASCA 71 S Doyle JA
39
because it is violence of a different general nature to, or fundamentally different in
kind from, the possibility of violence that had been agreed.
156 The typical case in which there might be a relevant difference between the
violence agreed and the violence that occurred is where the latter involves the
introduction of a weapon when the agreement did not include the use of any
weapon at all. A relevantly fundamental departure from what had been agreed as
possible might fairly readily be inferred in that situation.
157 However, such an inference will not always be appropriate. As was seen in
R v Betts, the mere fact that the primary offender used an implement (concealed in
his fist, without the knowledge of the secondary offender) which had not been
agreed did not take the violence outside the scope of the agreement. In the
circumstances of that case, this was a mere difference in the manner of execution,
and not a departure from the type of violence which had been agreed as possible.
158 Difficult issues may also arise in cases where the weapon used differs from
the one agreed to, or where an agreed weapon is used in a manner or for a purpose
which has not been agreed as a possibility.
159 The English courts have grappled with issues of this nature in the so-called
‘knowledge-of-the weapon’ cases. In addressing the scope of a secondary party’s
responsibility for murder pursuant to a joint enterprise or common purpose, those
cases have considered the circumstances in which there is a sufficiently
fundamental difference between what is agreed or foreseen and what occurs to
prevent a secondary party being liable for the consequences of a principal’s
criminal violence.
160 In R v Powell (Anthony),122 the secondary party had agreed to participate in
an attack using wooden posts, but the primary offender used a knife and killed the
victim. In holding that the secondary party should have been acquitted if he had
not foreseen the possible use of a knife, the House of Lords accepted that the use
of a knife was fundamentally different from, and hence outside the scope of, the
parties’ agreement. However, their Lordships added that if the weapon used had
merely been ‘different to, but as dangerous as’ the weapon which the secondary
contemplated might be used, then the secondary party should not escape liability
for murder.
161 In R v Rahman,123 the four accused men, with others, and armed with blunt
instruments, attacked the victim, but the cause of death was a stab wound. It was
not possible on the evidence to identify the principal offender. In the House of
Lords, the majority formulated their approach in terms that the secondary party (B)
would not be liable for murder if: (i) the principal offender (A) suddenly produces
and uses a weapon, of which B knows nothing, and which is more lethal than any
122 R v Powell (Anthony) [1991] 1 AC 1 at 30 (Lord Hutton).
123 R v Rahman [2009] 1 AC 129 (Rahman).

40
weapon which B contemplates that another participant may be carrying; and (ii)
for that reason, A’s act is to be regarded as fundamentally different from anything
foreseen by B.124 Lords Bingham and Scott, on the other hand, took an approach
which focussed more upon the purpose of the agreed enterprise than the type of
weapon anticipated.
162 Lord Bingham, for example, saw the case as turning on the principle that ‘a
radical departure by the primary killer from the foreseen purpose of an enterprise’
might relieve the secondary party of liability, adding:125
… The greater the difference between the acts and behaviour in question and the purpose
of the enterprise, the more ready a jury may be to infer that the particular defendant did not
foresee what the other participant would do.
163 To similar effect, Lord Scott said:126
… It seems to me beside the point that the secondary party may not have known the killer
to be carrying the weapon actually used to effect the killing and I do not understand how
his criminality can be held to depend on whether the killing stroke was effected by the club
the killer was known to have carried or by the knife that he was not known to have carried.
It would, of course, be necessary that the killing stroke should have been an act within the
scope of the joint enterprise on which the parties had embarked but if the parties embark
on a punishment exercise that carries with it the foreseeable possibility of death of the
victim the instruments used for that purpose seem to me of much less important than the
purpose itself.
164 To summarise the approach adopted in the English cases, common purpose
liability relevantly turns on whether the actions of the principal were
‘fundamentally different’ from those foreseen by the secondary party. The
determination of this issue will be heavily influenced by the secondary party’s
knowledge of the weapon used, and whether it was a weapon of equivalent or
greater dangerousness than any weapon that the secondary party contemplated
might be used. However, the determination of this issue is not necessarily
controlled by the secondary party’s knowledge of the weapon used, as this needs
to be considered in the context of the purpose of the joint enterprise.
165 The Supreme Court of New Zealand considered these English cases in
Edmonds v The Queen.127 In attempting to ensure an appropriate correlation
between what had been agreed or foreseen, and the criminal acts for which liability
will attach, their Honours supported a broader focus upon the circumstances and
agreed purpose, as opposed to the secondary party’s knowledge of the particular
weapon that might be used. Their Honours explained:128

Although the English courts have now reached the position that the application of the
‘fundamentally different’ test is not confined to knowledge-of-the-weapon considerations,
such considerations still seem to be of central importance. This is despite the reality that
the magnitude of the risk of death (or other serious injury) recognised by the alleged party
cannot be accurately assessed by reference primarily to whether that party knew of the
presence of the fatal weapon or one which was similarly lethal. A knife intended to be used
only in extremis and in self-defence may pose far less risk of harm than a baseball bat
which is to be used against the head of the victim. The likelihood of serious injury or death
predominantly depends on the personalities and intention of those engaged. Relevant to
this will be their states of emotional arousal, whether they have consumed alcohol or drugs
and similar considerations. Far more important than the precise nature of the particular
weapons they have is what they intended to do with them. So treating party liability as
dependent on awareness that one or more of the participants were armed with the weapon
used by the principal (or an equally dangerous weapon) cannot produce anything like a
precise correlation of common purpose liability with the accuracy of the alleged party’s
foresight of the extent of the risk of death or serious injury. As well, legal principles which
depend on a comparison of the dangerousness of weapons encourage attempts to make
unmeritorious (and perhaps faintly ludicrous) distinctions.
166 In my view, these authorities support the potential relevance of both the
purpose and degree of the violence in determining whether the prosecution has
established the requisite correspondence between the violence that was agreed and
the violence that occurred; that is, in determining whether the violence that
occurred was of the same general nature of that which had been agreed as a
possibility, or was fundamentally different in some way. Whilst the defendant’s
agreement to, or knowledge of, the type of weapon to be used will often be
significant in this determination, its significance will depend on the circumstances
of the particular case. Those circumstances may include the personalities and
states of emotional arousal or intoxication of the people involved, and any other
matters bearing upon their intentions, purpose and potential use of any weapons or
implements in their possession.
167 In summary, there is no conceptual difficulty with an approach, reflected in
the approach taken by Stein J in the present case, which involves acceptance that
the defendant agreed to the possibility of some violence, and even some violence
with the weapon that was used, but a conclusion that the violence that occurred
was nevertheless not of the same general nature as that which had been agreed. At
the same time, it is fair to say that inferring a limit upon the nature of the violence
that has been agreed as a possible incident of a JCE, or even allowing for the
reasonable possibility of such a limit, should be approached with some caution.
There must be some basis in the evidence for the limit. In circumstances where
the defendants have agreed to use violence in order to commit a crime, and there
is no reason for them to have turned their minds to the nature of the violence that
might be involved, it may be difficult to find a basis for inferring or allowing for a
relevant limit upon the nature of the violence that has been agreed. That is
particularly so bearing in mind that agreement to violence of a particular nature as
a possibility does not require an intention, let alone desire, that violence of that
nature will be used. The agreement to violence of that nature may be contingent
and reluctant.

168 In making these observations, I have not overlooked that the onus lies on the
prosecution to establish the breadth of the agreement; and hence that the onus lies
on the prosecution to establish that the agreement extended to the possibility of
violence of the same general nature as that which occurred and caused death.
However, the point being made is that where the prosecution has established
beyond reasonable doubt that the defendants agreed to the possibility of violence
using a weapon, it may be difficult to identify any limit upon the breadth of the
possible violence encompassed within that agreement.
169 The Director contends that, even if there was no conceptual difficulty with
the approach taken, and the distinction drawn, by Stein J in the present case, it was
not supported by the evidence. Before addressing this contention (which is the
focus of Ground 2) more directly, it is convenient to first address the Director’s
contention that is the subject of Ground 1.
Ground 1 – failure to properly consider the prosecution’s second pathway
170 Through Ground 1, the Director contends that Stein J failed to grapple with,
or erroneously rejected, the prosecution case that the agreement to which
Mr Howell was a party was an agreement to use any, or whatever, force was
necessary to achieve the plan to steal cannabis from the grow house.
171 In support of this contention, the Director argues that the judge erred, or at
least distracted herself from the appropriate question, by focussing upon whether
or not Mr Howell had agreed to violence that included the possibility of lethal or
fatal violence. It is true that Stein J said (in paragraphs [521]-[522]) that the
evidence did not establish that the agreement included the possibility of lethal or
fatal force. However, read in context, these passages do not demonstrate any
misunderstanding by her Honour of either the prosecution case, or the issues to be
determined. These passages were merely the first step in her Honour’s reasoning
towards a rejection of the argument that the agreement extended to the use of any
level of violence (paragraphs [515], [521]), or whatever force was necessary, and
ultimately concluding that the agreement was limited to the possibility of violence
to subdue. The first step in this reasoning was a finding that the agreement did not
include the possibility of lethal or fatal force. This finding was supported by the
fact that the men were armed only with a bat, and not knives or guns. The second
step in her Honour’s reasoning was a finding (paragraphs [559]-[560]) that it was
reasonably possible that the agreement was confined to the use of the bat to subdue
(even if by striking and causing serious injury to the occupant), as opposed to use
of the bat to strike aggressively with sufficient force to fracture the occupant’s
skull. It was through these two steps that Stein J ultimately concluded that the
prosecution had not established that the agreement encompassed the possibility of
violence of ‘the same general nature’ as that which occurred.
172 The judge’s first step and finding did not involve any misunderstanding of
the prosecution case. It did not involve any misunderstanding to the effect that the
prosecution case involved an agreement to use lethal force, in the sense of an
-- 46 of 84 --
[2026] SASCA 71 S Doyle JA
43
agreement to kill or commit grievous bodily harm. As the Director correctly points
out, the prosecution did not allege common law murder by JCE. Its case for
common law murder was confined to a case invoking the principles of EJCE. But
the judge’s reference to lethal force was not addressing a perceived case of
common law murder by JCE. Rather, as explained, it was simply a step in her
rejection of an agreement framed in terms of an agreement to use any or whatever
force was necessary to achieve the plan to steal cannabis, and in support of her
ultimate conclusion in the context of the second pathway to guilt (constructive
murder through JCE) that the agreement was limited in terms of the violence it
encompassed.
173 It is not to the point that the two steps in the judge’s reasoning, and two
findings, were made in separate passages of her Honour’s reasons. Even though
related in the way I have described, it was understandable and appropriate that the
first was made in the context of her Honour’s initial consideration of the scope of
the parties’ agreement (which was relevant to both pathways to guilt contended for
by the prosecution), and the second was made in the context of her Honour’s
reasoning directed squarely to the second pathway of constructive murder through
participation in a JCE.
174 When understood in this way, it is apparent that Stein J has neither
misunderstood, nor failed to address, the prosecution’s second pathway to guilt.
The Director’s submissions to the contrary should be rejected.
175 As to whether the judge erred in rejecting the prosecution’s second pathway
to guilt, I have already explained that it was conceptually open to the judge to find
that the scope of the agreement did not extend to the possibility of any, or whatever,
violence was necessary to achieve the plan to steal cannabis from the grow house.
It was open to the judge to find that the agreement contemplated a more limited
use of violence. Whether the evidence justified a finding to this effect is a matter
to be addressed in the context of Ground 2.
Ground 2 – violence not of the same general nature that was agreed
176 The Director contends that Stein J erred in finding that it was reasonably
possible that the agreement was confined to the possible use of the bat to subdue
(even if striking and causing serious injury to the occupant), as opposed to the
possible use of the bat to strike the occupant aggressively to the head with
sufficient force to fracture his skull. The Director contends that her Honour erred
both in accepting that there was a factual basis for this limitation upon the
agreement, and in concluding that any such limitation warranted a conclusion that
the violence used was not of the same general nature as that which had been agreed.
177 In support of his challenge to Stein J’s reasons and conclusion, the Director
relies upon the following features of the evidence:
• Mr Howell was party to an agreement to steal cannabis from a grow house;
-- 47 of 84 --
[2026] SASCA 71 S Doyle JA
44
• the agreement included Mr Howell and four other men;
• Mr Howell was aware there was an occupant in the grow house likely to resist
theft;
• one of their number was armed with a bat, and the agreement encompassed
the authorisation of the use of force to threaten and subdue the occupant to
deter him from interfering in the theft;
• Mr Howell was aware of the bat;
• the death of the deceased was caused by a blow (or blows) from an object
consistent with the bat; and
• in his record of interview, Mr Howell said: that he observed Mr Rigney
holding a cricket bat; that prior to entry into the grow house, Mr Rigney
threatened him with the bat, including threatening to ‘cave your fucking head
in’; and that he observed Mr Rigney strike the deceased across the head with
the bat.
178 All of these matters were, of course, relevant to the judge’s determination of
the scope of the agreement, and in particular the nature of the violence which
Mr Howell and others had agreed would be a possible, even if only contingent and
reluctant, incident of their plan to steal cannabis. As a result, there was no doubt,
as the judge found, that the agreement encompassed some level of violence. The
fact that they went in numbers, were expecting resistance from an occupant and
had a weapon made this inference irresistible.
179 In considering the nature of the violence that had been agreed, because the
agreement may well have been tacit, and the judge was left to infer its scope from
the circumstances, it was appropriate to approach the task of determining the scope
of the agreement at a relatively general level. Further, given that the men, when
entering the grow house, were entering an uncertain and potentially volatile
situation, and were likely to have been on edge and full of adrenaline, it was
appropriate to be cautious in inferring any clear limit on the violence that had been
agreed.
180 However, it did not necessarily follow that Mr Howell and others reached an
open-ended agreement to use whatever violence one of their number might have
decided to inflict. In my view, it remained open for the judge to accept, at least as
a reasonable possibility, that Mr Howell had not agreed to violence extending
beyond the use of the bat to subdue the occupant. In allowing for the possibility
that the agreement was limited in this way, I do not think the judge erred in
emphasising that the weapon the men took with them was a bat, rather than a knife
or gun. Whilst bats can, of course, be deployed in varying ways, and can be used
aggressively to cause very serious harm, the nature of the weapon was nevertheless
a relevant, indeed significant, consideration in the present case. It was also
-- 48 of 84 --
[2026] SASCA 71 S Doyle JA
45
relevant that the evidence only established that one of the defendants was carrying
a weapon. These considerations were consistent with a purpose which was
focussed upon achieving an objective of stealing the cannabis, without any
agreement that there would be any serious or gratuitous violence directed towards
the anticipated occupant.
181 The Director challenges the judge’s reliance upon Mr Howell’s distressed
state in the aftermath of the events on the night of 8 October 2018, as described by
his then partner, CD, and friends TL and JL. Whilst the judge relied upon this
distress as supporting the possibility that Mr Howell had not agreed to, or even
foreseen, violence of the nature that occurred (paragraph [533]), the Director
submits that this distress was just as easily explained by the fact that the death of
the occupant was not part of the agreed plan. Even accepting that it was not
appropriate to make any clear finding as to the precise reason for Mr Howell’s
distress, I see no difficulty with her Honour relying upon this evidence as
supportive of the possibility which she concluded had not been excluded.
182 In summary, the matter was finely balanced. I have some reservations in
accepting the limitation upon the agreed violence identified by the judge.
However, the issue is not one which permits of any clear answer. There is scope
for reasonable minds to differ as to the appropriate inference to be drawn. In my
view, it was at least open to Stein J to draw the inference she did, and hence to
allow for a reasonable possibility of the limit she identified upon the nature of the
violence that had been agreed as a possible incident of the plan to steal cannabis
from the Carousel Street grow house. Given Stein J’s advantage, even if relatively
slight, in hearing the witnesses give evidence, and considering the evidence more
generally in the atmosphere of the trial as it unfolded, I am not persuaded that
Stein J was wrong to reach the conclusion and verdict that she did.
183 Further, assuming that it was reasonably possible that the agreement was
limited in the way identified by Stein J, I agree with her Honour that the violence
in fact perpetrated on the occupant, Mr Gjabri, was not violence of the same
general nature as that which had been agreed as a possible incident of the plan to
steal the cannabis. The aggressive, and seemingly unnecessary and gratuitous,
striking of Mr Gjabri to his head, with sufficient force to fracture his skull, was a
fundamental departure from violence for the purpose of subduing Mr Gjabri so as
to enable the men to take the cannabis they had come to steal.
184 Although not strictly arising under Ground 2, I add for completeness that at
times the Director’s submissions strayed beyond asserting error in the judge’s
conclusion that the violence that occurred was not of the same general nature as
that which had been agreed, and included the assertion of error in the judge’s
conclusion that it had not been proved that Mr Howell foresaw violence involving
the infliction of death or grievous bodily harm with murderous intent.129 In straying
from addressing what Mr Howell had agreed, to what he had foreseen, the
129 Director’s written submissions on the Howell appeal, paragraphs [180]-[183].
-- 49 of 84 --
[2026] SASCA 71 S Doyle JA
46
Director’s submissions strayed from a challenge to the judge’s rejection of the
prosecution’s second pathway to guilt (constructive murder using the principles of
JCE) to a challenge to the judge’s rejection of the prosecution’s first pathway to
guilt (common law murder using the principles of EJCE). Whilst there was no
ground of appeal which enabled a direct challenge to the judge’s rejection of this
first pathway to guilt, there is no need to consider whether the Director’s grounds
might be amended to permit this challenge. There is no need because, in my view,
the challenge would face the same obstacles as the challenge to the second pathway
to guilt. Whilst there is obviously a conceptual difference between what
Mr Howell might have foreseen as a possible incident of the plan to steal cannabis
(for the first pathway) and what he agreed as a possible incident of that plan (for
the second pathway), there is nevertheless a close relationship between the two.
Having explained my reasons for rejecting the Director’s challenge to the judge’s
conclusion that it was possible that Mr Howell had not agreed to the possibility of
violence of the same general type as that which occurred, I would, for essentially
the same reasons also reject any challenge to her Honour’s conclusion that it was
possible that Mr Howell did not foresee the possibility of violence involving the
infliction of death or grievous bodily harm with murderous intent.
Ground 3 – adequacy of reasons
185 The principles governing the adequacy of a judge’s reasons are well known,
and not in dispute. They were summarised by the High Court in DL v The Queen.130
186 Although Ground 3 involved a complaint of inadequate reasons, this was not
the focus of the Director’s submissions on appeal. In essence the Director’s
submissions under this ground were to the effect that even if Stein J’s conclusions
the subject of challenge under Grounds 1 and 2 were not erroneous, her Honour
did not adequately set out her reasons for the conclusions she reached. In short, I
do not consider that there is any merit in this complaint. As my summary and
analysis of her Honour’s reasons demonstrate, far from being inadequate, her
reasons were careful and thorough. Properly understood, her reasons squarely
addressed the prosecution case in respect of both pathways to guilt, and clearly
exposed her reasons and conclusions in relation to each of the key steps in her
Honour’s rejection of the prosecution case in relation to common law and
constructive murder. This includes those aspects of her Honour’s reasons relating
to the difference between the violence which her Honour considered had been
agreed or foreseen, and the violence which in fact occurred and caused Mr Gjabri’s
death.
Conclusion
187 Even though I would grant permission to appeal, the Director has not
ultimately established any error of law or principle. Although I have expressed
some reservations about the judge’s factual conclusion as to the scope of the
agreement to which Mr Howell was a party, I am satisfied that her Honour’s
130 DL v The Queen (2018) 266 CLR 1 at [32]-[33] (Kiefel CJ, Keane and Edelman JJ).
-- 50 of 84 --
[2026] SASCA 71 S Doyle JA
47
conclusion was at least open on the evidence at Mr Howell’s trial. As this is an
issue of fact only, and because allowing the appeal would expose Mr Howell to a
third trial, I do not consider that any error on this issue would be an appropriate or
sufficient basis for this Court’s intervention. It is therefore not necessary for me
to reach a concluded view as to whether the judge’s conclusion as to the scope of
the agreement was correct, as opposed to merely open.
188 For the reasons given, I would dismiss the Director’s appeal against
Mr Howell’s acquittal of murder.
PART C: APPEAL IN MITCHELL, RIGNEY, CARVER & TENHOOPEN
The trial
189 The prosecution case against Mr Mitchell, Mr Rigney, Mr Carver and
Mr Tenhoopen for the murder of Mr Gjabri involved the same two pathways to
guilt as the case against Mr Howell; that is, by reason of common law murder
through participation in an EJCE, or constructive murder pursuant to a JCE.
190 At a general level, the evidence in the joint trial of these men was similar to
the trial evidence led in the trial of Mr Howell. At a more detailed level, there
were a number of differences in the evidence between the two trials, and indeed in
the evidence which was admissible against the individual defendants in the joint
trial. Some of these differences are identified in the summary that follows.
However, as was the case with the Director’s appeal from Mr Howell’s acquittal
for murder, the appeals brought by Mr Mitchell, Mr Rigney, Mr Carver and
Mr Tenhoopen against their convictions for murder are focussed upon challenges
to the inferences or conclusions drawn by the trial judge (particularly as to the
scope of the defendants’ agreement) rather than any challenge to her findings of
primary fact.
191 In the circumstances, it is not necessary to identify in any detail the evidence
that was led during the joint trial. It is sufficient to observe that it included
evidence:
• in relation to Mr Gjabri, the Carousel Street premises and the cannabis
operation at that premises;
• from investigating police officers about their investigation of, and their
collection of forensic samples and other evidence from, the Carousel Street
premises and surrounding areas;
• from civilian witnesses in relation to observations they made of the
defendants transferring the bags of cannabis from Mr Gjabri’s car to their
cars in Gilbert Street, Ingle Farm;
-- 51 of 84 --
[2026] SASCA 71 S Doyle JA
48
• from the forensic pathologist, Dr Charlwood, who gave evidence about
Mr Gjabri’s injuries and cause of death in terms very similar to the evidence
she gave at Mr Howell’s trial;
• from CCTV cameras of the defendants driving and walking in the area of the
Carousel Street premises, as well as evidence from two experts about some
technical aspects of that footage;
• from telephone towers about the location of the mobile phones connected to
various of the defendants during the night of 8 October 2018;
• from traffic cameras about the location of cars connected to Mr Rigney and
Mr Mitchell during that night;
• from Ms McCormack (Mr Tenhoopen’s then partner), Ms Carson (who was
a friend of Mr Tenhoopen, and knew Mr Mitchell), Mr W (who was a cell
mate of Mr Tenhoopen in late 2018) and some other civilian witnesses about
matters including observations they made of, and conversations they had had
with, various of the defendants;131
• of conversations with some of the defendants recorded through the use of
listening devices;
• of searches made of the places the defendants were living; and
• from experts as to the forensic testing carried out on some of the items seized
during police searches.
192 The evidence also included a record of Mr Mitchell’s evidence in an earlier
trial of the same charges, as well as a record of his police interviews.
193 The judge’s reasons included a lengthy summary of the evidence led at trial.
However, for the reasons explained, it is not necessary to say anything further
about the detail of this evidence.
The defence cases
194 McIntyre J’s reasons included a brief outline of the defence case for each
defendant.132 Their cases differed in detail, including in response to the differences
in the evidence as to their knowledge of what was to occur when they attended the
Carousel Street premises, and their level of involvement in what occurred at those
premises. But there was a similar focus, with all of them denying that they agreed
to, or foresaw, the use of violence, and in particular violence of the nature that
occurred and resulted in Mr Gjabri’s death. They emphasised various features of
131 This included some evidence from Mr Howell’s partner, CD, although her evidence in this trial was
limited to some observations she made on the night of 8 October 2018, and did not include the
admissions by Mr Howell about which she gave evidence in his trial.

49
the evidence said to support their lack of agreement to, or foresight of, any
significant violence, including: the limited evidence of any sophisticated or careful
planning; the possibility that the item being held by one of their number could have
been picked up spontaneously as they were approaching (given that it was not able
to be seen in some of the early CCTV footage); their limited attempts to avoid
noise or detection whilst stealing the cannabis; and the possibility (advanced on
behalf of Mr Tenhoopen) that Mr Howell went back inside the Carousel Street
premises to ‘finish off’ Mr Gjabri after they had stolen the cannabis and so after
any joint enterprise had been completed.
The judge’s findings
195 McIntyre J found that the Carousel Street house was being used as a grow
house for a sophisticated commercial cannabis operation.133
196 Based on a combination of the CCTV footage, traffic cameras and mobile
phone evidence, the judge made a number of findings as to the events on the night
of 8 October 2018.134 They included a finding that each of the defendants was in
the vicinity of the Carousel Street premises at the time of the robbery, having
arrived in Para Vista at about 11.30pm. Mr Rigney had travelled to the area from
Prospect in his Holden Commodore; the others had travelled there from Murray
Bridge in Mr Mitchell’s Subaru. Mr Rigney and Mr Carver were in telephone
contact in the lead up to their arrival. Several figures could be seen from the CCTV
footage to be walking through the surrounding streets, towards the Carousel Street
grow house, arriving at that location at about 12.07am.
197 The judge accepted that a finding that one of the defendants was carrying a
weapon was an indispensable link in the prosecution case, and hence needed to be
found beyond reasonable doubt.135 Whilst apparently accepting that a finding that
all defendants were present at the grow house was also an indispensable link, her
Honour did not consider it necessary to find that they all entered the grow house.136
198 The judge acknowledged the variable, although generally poor, quality of the
CCTV footage.137 However, relying primarily upon some footage from between
12.05am and 12.06am in nearby Lorraine Street, the judge found beyond
reasonable doubt that there were five people in the footage, and that one of those
people could be seen walking on the footpath and holding an unidentifiable
elongated object which she described as a ‘pole like’ item.138 In finding that five
were present in the group approaching the grow house, McIntyre J rejected
Mr Mitchell’s case that he did not leave his car.

199 On McIntyre J’s findings,139 entry was gained to the Carousel Street premises
shortly after 12.07am. From about 12.28am the defendants could be seen loading
cannabis into Mr Gjabri’s car in the driveway of the Carousel Street premises.
After being at the Carousel Street premises for around 15 to 20 minutes, the
defendants left in Mr Gjabri’s car at about 12.33am. The defendants collected their
cars and drove to a location in Gilbert Street, where they transferred the cannabis
into their cars and abandoned Mr Gjabri’s car. Both Mr Mitchell’s Subaru and
Mr Rigney’s Commodore were on the South Eastern Freeway travelling towards
Murray Bridge at about 1.30am, and Mr Mitchell, Mr Carver and Mr Tenhoopen
were back in Murray Bridge by about 2.00am.
200 Turning to the cause of Mr Gjabri’s death, the judge made the following
findings about his injuries and death:
[283] I accept Dr Charlwood’s evidence. I find on the basis of that evidence and the other
evidence that:
• The cause of Mr Gjabri’s death were head injuries caused by blunt force
trauma.
• The injuries are consistent with the use of a bat or solid pole.
• The head injuries were not inflicted by a brick or bricks.
• The force used to inflict the head injuries was severe in nature.
• The head injuries were likely caused by more than one blow, but I cannot
exclude the possibility that they were caused by one severe blow.
• Mr Gjabri did not die immediately after the infliction of the head injuries. He
survived for between 30 minutes and 24 hours. He moved around the house
as evidenced by the blood spatter on top of cannabis remnants, attempts to exit
the front door and vomit.
• Mr Gjabri was not tied up nor did he have any wounds consistent with the use
of knife.
• The other injuries noted on Mr Gjabri’s limbs and torso are consistent with a
struggle over the laundry/kitchen door and forcible efforts on the part of the
robbers to keep him in the lounge kitchen area to facilitate the theft of the
cannabis.
201 Despite thorough searches of the Carousel Street premises and the
surrounding area, the weapon used to assault Mr Gjabri was not located.140
202 The judge addressed in some detail the use she made of the evidence of
Ms McCormack and Ms Carson,141 noting the respects in which their evidence was

admissible against some defendants but not others. As mentioned earlier, each
gave evidence of their observations of, and conversations with, some of the
defendants both before and after the theft of the cannabis, with their post-theft
evidence including conversations when in Queensland from 15 to 18 October 2018
with Mr Mitchell, Mr Carver and Mr Tenhoopen. Most of this evidence was only
admissible as against Mr Mitchell and/or Mr Tenhoopen, although some of the
Queensland evidence was also admissible against Mr Carver. The evidence of
Ms McCormack and Ms Carson included various admissions by the defendants in
relation to their involvement in the theft of the cannabis. However, it also included
some other matters of detail. For example, Ms McCormack gave evidence that
Mr Tenhoopen told her that Mr Rigney and Mr Howell were beating up the male
occupant, that Mr Rigney told him to hit the male, and that he did hit him on the
arm. And Ms Carson gave evidence that Mr Tenhoopen told her that a man had
been tied up and hurt with bats, that he had been instructed to hit the man with a
bat, and that he did so once on his arm. Ms McCormack also gave some evidence
about Mr Tenhoopen telling her that when they were leaving, he saw the man
looking through the window, and that Mr Howell ‘went back into the house and
finished him off’.142
203 As the judge observed, some of the things that Ms McCormack and
Ms Carson said they were told were supported by, or at least consistent with, the
other evidence at trial. However, as the judge also observed, some of it was not.
There were challenges to the credibility and reliability of both of these women,
including on the basis of their heavy cannabis use. However, after setting out the
relevant aspects of their evidence, the judge concluded that ‘overall’ their evidence
was truthful and reliable, and accepted it save where indicated in her Honour’s
reasons.143
204 The judge accepted that the evidence of Mr Mitchell, Mr Carver and
Mr Tenhoopen suddenly travelling to Queensland between 15 and 18 October
2018, at a time when there was media commentary about the cannabis theft and
death of Mr Gjabri, was probative of a consciousness of guilt on the part of these
men in respect of the theft of cannabis. However, her Honour regarded it as neutral
in relation to their responsibility for Mr Gjabri’s death, given that their trip was
consistent with a desire to escape an unfair accusation of involvement in his death
(in circumstances where they had been involved in a plan to steal cannabis, but not
to cause harm to Mr Gjabri).144
205 McIntyre J next embarked upon a consideration of various aspects of the
evidence which was only admissible or relevant in relation to particular
defendants.145 Much of this related to evidence intended to establish the relevant

challenge on appeal, and is addressed in more detail later in these reasons.

defendant’s involvement in the theft of the cannabis, as opposed to the extent of
any violence which they agreed or foresaw might be used, and does not need to be
addressed in detail given the focus of the issues raised on appeal. It is sufficient
for the purposes of this appeal to mention the following matters in relation to the
prosecution cases against Mr Tenhoopen and Mr Mitchell.
206 In the case against Mr Tenhoopen, the judge accepted the evidence of Mr W,
Mr Tenhoopen’s cell mate in late 2018, to the effect that Mr Tenhoopen made
admissions to him about not only his involvement in the theft of cannabis, but also
the use of violence in that theft.146 As to the latter, the admissions to Mr W included
statements that there had been a struggle with the occupant in a doorway, that the
occupant had been hit over the head, and that the occupant was then taken to
another room where the group took turns watching him while the others collected
the drugs. The admissions did not include any reference to who had struck the
blow to the occupant’s head, or what was used to strike that blow. The judge also
accepted that a listening device recording of a statement by Mr Tenhoopen to
Ms McCormack (‘oh well, shit happens hey, sometimes you have to go in and
fucking hurt someone too much’) was an admission of his awareness of events on
the night of the cannabis theft, including Mr Gjabri being hurt,147 and ultimately an
admission of his involvement in that theft.148
207 In the case against Mr Mitchell, the judge largely rejected the version of
events he gave in his evidence at the earlier trial, including that he did not have
any discussion with the other defendants about what their plans were on the night
of 8 October 2018, and that he stayed in the car where they parked in Para Vista
and so did not attend the Carousel Street premises. The judge also found that
Mr Mitchell told various lies to the police, holding that they demonstrated ‘a
consciousness of guilt at least in relation to the cannabis theft.’149
The judge’s operative reasoning
208 After making detailed findings as to the primary facts, including the key
findings mentioned above, McIntyre J turned to address her ultimate conclusions.
209 Her Honour commenced this section of her reasons by finding beyond
reasonable doubt that there was a plan between all four defendants and Mr Howell
to steal the cannabis from the Carousel Street premises.150 Her Honour then set out
some brief defendant-specific reasons for reaching this conclusion.151
210 The judge next turned to whether the defendants’ plan to steal cannabis
included any threat or use of force. Her Honour commenced by noting that
although there was no direct evidence from any defendant as to their intentions,

53
Mr Tenhoopen had made some admissions to Ms McCormack, Ms Carson and
Mr W. However, as there was no like evidence in respect of the other defendants,
their intentions fell to be inferred from the surrounding circumstances.152
211 The judge concluded that the defendants’ agreement to steal cannabis did
involve an agreement ‘to use force against any occupant in order to carry out the
theft’.153 In support of this conclusion, her Honour emphasised the extent of the
defendants’ planning and opportunity to discuss their plan, the likelihood that
someone would be present and offer resistance, and their forceful entry and
approach to the theft more generally:
[377] The plan to steal cannabis may not have been sophisticated or meticulously planned
but neither was it spur of the moment or opportunistic. 17 Carousel Street had been
identified and was targeted. The defendants did not simply happen upon a
commercial grow house. I infer that at least one of the defendants had some
knowledge of this and that this information was shared between them.
[378] Carver, Tenhoopen, Mitchell and JPH travelled some distance from Murray Bridge
to Para Vista. Carver liaised with Rigney. All five converged near Carousel Street
within minutes of each other. Each vehicle drove past the premises before parking
in a nearby street. I infer that they were checking the premises before embarking on
their planned activities. None of this was a coincidence. It was part of a plan
between the five of them.
[379] The general circumstances suggest a forceful approach to the theft of the cannabis.
There were five of them. They did not gain entry to the house in a surreptitious or
stealthy manner – they used body force to break through the front door. They used
a similar approach to the rear door exit. Whilst the defendants may have hoped that
there was no one at the house they must have been alert to the possibility that
someone might be present. Cannabis is a valuable commodity. It is common for
someone to reside at a grow house in order to safeguard the crop. The likelihood
that there was someone at the house was reinforced by the fact the presence of
Mr Gjabri’s car was obvious in the driveway.
[380] The defendants walked a circuitous route from the location where they parked their
cars to 17 Carousel Street. It took them approximately 25 minutes. It is
inconceivable that they did not discuss their plans, including what to do with any
occupant of the grow house, during that walk. The defendants must have
contemplated that anyone in the house would resist their efforts to take the cannabis
and might also call for backup. I find beyond reasonable doubt that the agreement
to steal the cannabis involved an agreement to use force against any occupant in
order to carry out the theft. …
212 McIntyre J noted the submissions by Mr Mitchell and Mr Rigney to the effect
that it had not been established beyond reasonable doubt that they entered the
house. Her Honour explained that it was not necessary to make a finding to this
152 Reasons [376].
153 Reasons [380].

[2026] SASCA 71 S Doyle JA
54
effect. It was sufficient to be satisfied, as she was, that they were each party to the
plan, and participated in it.154
213 In reiterating her findings as to causation, the judge said that Mr Gjabri’s
death was caused by ‘one or more severe blows to the head with a weapon’.155
Those blows were deliberate, voluntary and unlawful. The weapon has never been
found.
214 The judge returned to the topic of the long ‘pole like’ object that one of the
defendants was carrying shortly prior their arrival at the Carousel Street premises.
Her Honour found that the defendants’ plan to steal cannabis included ‘the possible
use of the weapon to assault any occupant’ of the Carousel Street premises:
[382] I have found that footage 10 from 33 Lorraine Avenue shows one of the defendants,
or JPH, walking on the footpath carrying a long pole like object shortly before they
gained entry to the house. All of the co-offenders are in close proximity to each
other. The presence of that object was obvious to all of them. The item was not used
to effect entry or exit. Unlike the secateurs or the knife, it is not the type of item that
could be used to harvest the cannabis. The injuries that caused Mr Gjabri’s death
are consistent with the use of an item such as that visible in the footage. No item
resembling the item in the footage was located by police either at 17 Carousel Street
or in nearby streets. It was, I infer, taken away and disposed of. There would be no
reason to dispose of the item if it was not used in some manner. I find that the item
visible in the 33 Lorraine Avenue footage was the weapon that inflicted the fatal
injuries on Mr Gjabri.
[383] I am satisfied beyond reasonable doubt that the plan between Carver, Mitchell,
Tenhoopen, Rigney and JPH to rob Mr Gjabri of his cannabis plants included the
possible use of the weapon to assault any occupant of 17 Carousel Street.
215 As to the first prosecution pathway to guilt of murder, namely common law
murder through participation in an EJCE, the judge acquitted the defendants on the
basis she was not satisfied beyond reasonable doubt that any of them foresaw that
one or more of their number might use a weapon to assault the occupant with the
intention of causing him death or grievous bodily harm:
[384] Murder contrary to s 11 of the CLCA by extended joint criminal enterprise requires
the foresight by each defendant that one of their number might, with murderous
intent, inflict GBH or death. I am satisfied that the plan between Carver, Mitchell,
Tenhoopen, Rigney and JPH to rob Mr Gjabri of his cannabis plants included the
possible use of the weapon to assault any occupant of 17 Carousel Street. In relation
to Tenhoopen and Carver, there is cogent evidence that they were both shocked and
distressed when they found out about Mr Gjabri’s death. I do not have any evidence
about Mitchell or Rigney’s state of mind on finding out about the death. I do,
however, accept the submission that it was unnecessary and indeed
counterproductive for the defendants to kill or inflict serious harm to any occupant
of the house in order to steal the cannabis. I cannot be satisfied that the defendants
contemplated that one or more of their number might use a weapon to assault
154 Reasons [380].
155 Reasons [381].
-- 58 of 84 --
[2026] SASCA 71 S Doyle JA
55
Mr Gjabri with the intention of causing him death or GBH. In those circumstances
I acquit the defendants of murder by extended joint criminal enterprise.
216 As to the second prosecution pathway to guilt of murder, namely constructive
murder pursuant to a JCE, the judge convicted the defendants on the basis that she
was satisfied that the act of intentional act of violence that occurred in furtherance
of the robbery and caused Mr Gjabri’s death was an act of ‘the same general nature’
as that which had been agreed (namely, an assault with the weapon they were
carrying):
[385] The robbery was a major indictable offence as defined in s 12A of the CLCA. I am
satisfied that hitting Mr Gjabri forcefully over the head with a weapon on one or
more occasions caused his death. I am further satisfied that it was an intentional act
of violence that occurred during the course, or in furtherance, of the robbery. I am
satisfied that whoever inflicted the fatal blow or blows is guilty of constructive
murder under s 12A of the CLCA. The identity of the offender or offenders who
inflicted the fatal blow or blows has not been established on the evidence. The
defendants can only be convicted of murder under s 12A as secondary offenders if
the prosecution has proven beyond reasonable doubt that, as part of their agreement
to commit the robbery, each of the defendants agreed to an intentional act of violence
of the same general nature as that which caused Mr Gjabri’s death. As outlined
above, I am satisfied that the planned robbery included an agreement, if necessary,
to assault any occupant of the grow house with the weapon I find that the defendants
took with them. An assault with the weapon is an intentional act of violence of the
same general nature as that which killed Mr Gjabri. Accordingly, I am satisfied that
each of the defendants is guilty of murder under the pathway provided by s 12A of
the CLCA.
217 As her Honour observed in concluding her reasons, having convicted the
defendants of murder, it was not necessary for her to consider the prosecution’s
alternative case for manslaughter.156
The grounds of appeal
218 There is a significant overlap between the grounds of appeal and submissions
advanced on behalf of each of the four defendants the subject of the joint trial. It
will be convenient to address many of their complaints collectively. That said, and
as will become clear, there are some complaints which focus upon the cases against
individual appellants.
Unreasonable verdict
219 Each of the appellants allege that their verdict of guilty of murder was
unreasonable.157 Although differing in their detail, there was a common theme to
the appellants’ submissions in support of this ground, namely that the evidence did
not support the judge’s conclusions that: (i) the ‘pole like’ item in the CCTV
footage was used to inflict the fatal blow(s) upon Mr Gjabri; (ii) the defendants
agreed to the possibility of violence in the course of their plan to steal cannabis

from the Carousel Street premises; (iii) the violence that occurred was of the same
general nature as that which had been agreed as a possible incident of the agreed
joint enterprise; and (iv) the fatal blow or blows occurred during the course of the
agreed joint enterprise.
220 Significantly, the appellants’ challenge to the judge’s conclusions in relation
to these matters, and thereby to her Honour’s ultimate conclusion of guilt, involve
a challenge to the inferences and conclusions drawn from the prosecution’s
circumstantial case as a whole. They do not involve any challenge to the judge’s
findings of primary fact.
221 Although (iii) and (iv) include submissions in support of the unreasonable
verdict ground, they also raise separate issues. I have addressed these in
subsequent sections of these reasons.
Principles governing a complaint of unreasonable verdict
222 The principles governing a complaint that a verdict is unreasonable are not
in dispute. They are the principles set out in M v The Queen.158 The central
question the Court must ask itself is ‘whether it thinks that upon the whole of the
evidence it was open to the jury to be satisfied beyond reasonable doubt that the
accused was guilty’, the question being one of fact which the Court must decide
by making its own independent assessment of the evidence.159
223 The application of these principles in the context of a trial by judge alone,
and a substantially circumstantial case, was considered by the High Court in
Dansie v The Queen.160 As the Court emphasised in that case, the function of the
appellate court is not confined to determining ‘whether there was error in the
factual findings on which the trial judge relied in ultimately finding the accused
guilty of the offence tried’.161 Rather, it is ‘to determine for itself whether the
evidence was sufficient in nature and quality to eliminate any reasonable doubt
that the accused is guilty of that offence.’162
224 In summarising the effect of M v The Queen, the High Court in Dansie
explained:163
The joint judgment in M made clear that "in answering that question the court must not
disregard or discount either the consideration that the jury is the body entrusted with the
primary responsibility of determining guilt or innocence, or the consideration that the jury
has had the benefit of having seen and heard the witnesses". The joint judgment equally
made clear how those considerations are to impact on the court's independent assessment

57
of the evidence. That was the point of the carefully crafted passage in which their Honours
stated:
‘It is only where a jury’s advantage in seeing and hearing the evidence is capable of
resolving a doubt experienced by a court of criminal appeal that the court may
conclude that no miscarriage of justice occurred [on the unreasonable verdict
ground]. That is to say, where the evidence lacks credibility for reasons which are
not explained by the manner in which it was given, a reasonable doubt experienced
by the court is a doubt which a reasonable jury ought to have experienced. If the
evidence, upon the record itself, contains discrepancies, displays inadequacies, is
tainted or otherwise lacks probative force in such a way as to lead the court of
criminal appeal to conclude that, even making full allowance for the advantages
enjoyed by a jury, there is a significant possibility that an innocent person has been
convicted, then the court is bound to act and to set aside a verdict based upon that
evidence. In doing so, the court is not substituting trial by a court of appeal for trial
by jury, for the ultimate question must always be whether the court thinks that upon
the whole of the evidence it was open to the jury to be satisfied beyond reasonable
doubt that the accused was guilty.’
225 Although expressed in terms of the relationship between the appellate court
and a jury, the observations are equally applicable in a case where the trier of fact
was a judge rather than jury. In other words, a reasonable doubt experienced by
the appellate court on its independent assessment may be a doubt that a reasonable
trial judge ought to have experienced, unless that doubt was capable of being
resolved by the trial judge’s advantage.
226 In a substantially circumstantial case such as the present, where the challenge
to the verdict turns on the inferences and conclusions to be drawn from primary
facts, rather than a challenge to those primary facts, the trial judge may not have
had any significant advantage. In that type of case, the appellate court, in carrying
out its independent assessment, will be required to weigh all of the circumstances
in deciding whether it was open to the jury to draw the ultimate inference that guilt
has been proved:164
Where the trial has been by judge alone, the reasons of the trial judge must be approached
by the court of criminal appeal performing that function with circumspection lest the
findings of fact made by the trial judge divert the court from undertaking the requisite
independent assessment of the evidence. The court will be required to consider the
arguments of the parties in the appeal and will be entitled to treat findings of fact made by
the trial judge about which no issue is taken in the appeal as an accurate reflection of so
much of the evidence as bore on those findings. But the question for the court in every case
will remain whether the court's assessment of the totality of the evidence leaves the court
with a reasonable doubt as to guilt which the court cannot assuage by having regard to such
advantage as the trial judge can be taken to have had by reason of having seen and heard
the evidence at trial.
The advantage that a trial judge might have had over a court of criminal appeal by reason
of having seen and heard the evidence at trial will vary from case to case depending on the
form in which the evidence was adduced at the trial and depending on the nature of the
issues that arose at the trial. In a case such as the present, where the prosecution case was
164 Dansie at [16]-[17] (the Court).
-- 61 of 84 --
[2026] SASCA 71 S Doyle JA
58
circumstantial, where the evidence adduced by the prosecution was largely uncontested and
for the most part in the form of transcripts of unchallenged testimony, and where the
appellant did not give evidence, the advantage must be slight.
227 The appellate court must form its own view as to the appropriate inferences
to be drawn from the evidence, albeit mindful that the ultimate issue is whether the
verdict reached by the trier of fact was ‘open’.
228 The case being a substantially circumstantial one in critical respects, the court
must be careful to take a holistic rather than a piecemeal approach to the evidence.
The court must be satisfied, as a result of its own assessment of the whole of the
evidence at trial, that the only rational inference available on that evidence was
guilt as charged.165 As it was put in R v Hillier:166
The case against Mr Hillier was a circumstantial one. It has often been said that a jury
cannot be satisfied beyond reasonable doubt on circumstantial evidence unless no other
explanation than guilt is reasonably compatible with the circumstances. It is of critical
importance to recognise, however, that in considering a circumstantial case, all of the
circumstances established by the evidence are to be considered and weighed in deciding
whether there is an inference consistent with innocence reasonably open on the evidence.
229 Whilst it is necessary to be satisfied that the prosecution has excluded any
inference or hypothesis consistent with innocence that is reasonably open, an
inference or hypothesis will not be reasonably open unless it rests on something
more than mere conjecture.167 It is not necessary to exclude a bare possibility that
has no foundation in the evidence.
230 In summary, the appellants are right to emphasise the importance of this
Court undertaking its own independent assessment of the evidence, and forming
its own view as to the inferences and conclusions to be drawn from that evidence.
This Court’s task is not confined to identifying error in the judge’s findings or
approach.168
231 At the same time, as acknowledged by the High Court in Dansie, the
appellate court must nevertheless remain mindful of the function played by the
trial judge and not simply substitute a trial by the appellate court for the trial that
has occurred. This deference to the function of the trier of fact is inherent in the
ground for interference being an ‘unreasonable’ verdict, and in the ultimate
question being framed in terms of whether it was ‘open’ to the trier of fact to be
satisfied beyond reasonable doubt that the accused was guilty, and hence whether
the trier of fact must have, as distinct from might have, entertained a reasonable
doubt about the defendant’s guilt.169

59
232 Although the High Court’s emphasis in Dansie upon the appellate court’s
own assessment of the evidence does not leave much room for deference to the
trial judge’s decision, I do not think that the reasoning in that case goes quite so
far as to suggest that the deference to the trial judge’s decision is strictly confined
to cases where the trial judge had some clear or obvious advantage. To go this far
would, it seems to me, risk subverting the role of the trier of fact, and substituting
trial by appeal. Particularly where the verdict turns upon an evaluative assessment
of a significant body of circumstantial evidence, the approach to be taken by the
appellate court, although requiring an independent assessment as described above,
does not always demand a conclusion that there was only one correct verdict.
There may, at least in some cases, be room for reasonable minds to differ, with the
result that the appellate court may be satisfied that the verdict was ‘open’ without
necessarily being satisfied that it was the only ‘correct’ verdict, or indeed that it
was the verdict the appellate court would have entered.
An agreement to steal cannabis from the Carousel Street premises
233 To the extent that the appellants challenge the conclusion that they were party
to an agreement to steal cannabis from the Carousel Street premises, there is no
merit in that challenge.
234 There was some evidence from Ms McCormack and Ms Carson, which was
admissible against Mr Mitchell and Mr Tenhoopen, of a discussion between those
two men about a plan to steal cannabis, including the need for Mr Mitchell to
‘change into some darker clothes’. However, even without any evidence of the
fact or content of any discussions between the defendants as to their plan for the
night of 8 October 2018, there was an ample basis in the evidence to infer the
existence of a plan to steal cannabis from the Carousel Street premises.
235 As mentioned earlier in these reasons, an agreement to embark upon a
criminal enterprise may be formed relatively spontaneously and may be inferred
from the defendants’ conduct. In the present case, there was no need to rely upon
any spontaneously formed agreement. The coordinated conduct of the defendants
in driving to a location near the Carousel Street premises, and then converging on
that location as a group is a sufficient basis to conclude beyond reasonable doubt
that their entry into the Carousel Street premises and theft of the cannabis occurred
pursuant to an agreement between them. Even allowing for the fact that one or
more of the defendants might have had earlier and more influential involvement in
forming the plan than the other defendants, it can be inferred beyond reasonable
doubt that, by at least the time they were approaching the Carousel Street premises
on foot, each of them knew and had agreed that they would steal cannabis from
that premises.
Each of the defendants participated in the joint criminal enterprise
236 Nor, in my view, was there any reasonable doubt that each of the defendants
participated in their joint criminal enterprise.
-- 63 of 84 --
[2026] SASCA 71 S Doyle JA
60
237 It is apparent from what occurred in the Carousel Street premises, including
not only the assault of Mr Gjabri, but also the cutting, bagging and removal of a
large quantity of cannabis, that most if not all of the defendants were physically
involved in the implementation of their agreement to steal cannabis.
238 It seems likely from what occurred that each of the men entered the Carousel
Street premises. However, even if one were to allow for the possibility that one or
two of the men did not enter the premises, that would not affect my conclusion that
each of the men participated in the implementation of their agreement to steal
cannabis. As McIntyre J explained when addressing a submission to this effect at
trial, it was not necessary for her Honour to find beyond reasonable doubt that each
defendant entered the premises.170 In the circumstances of this case, it would be
sufficient to establish participation that each defendant was present at the Carousel
Street premises, and in a position to assist to the extent necessary (for example, by
keeping a lookout outside the premises, by being ready to assist as required, or by
helping to load the cannabis into the car in the driveway).
The pole depicted in the CCTV footage was used to inflict the fatal blow(s)
239 As an aspect of their submission that the verdicts were unreasonable, the
appellants challenge the judge’s finding beyond reasonable doubt that the ‘pole
like’ item which one of them was seen carrying in the CCTV footage was used to
inflict the fatal blow or blows.
240 The first point to observe is that even though the judge accepted that a finding
to this effect was an indispensable intermediate finding in the pathway to guilt,
with the result that it needed to be made beyond reasonable doubt,171 I am not
persuaded that that was so.
241 In my view, a finding that one of the men was carrying this item (which I
shall refer to as ‘the pole’) as they approached the Carousel Street premises was
important, even if not quite indispensable, to a conclusion that the defendants’
agreement to steal cannabis encompassed the possibility of significant violence.
Relatedly, a finding that the other defendants were aware that one of their number
was carrying this item was also important, even if not quite indispensable, to that
conclusion. However, in my view, the evidence supported both of these findings.
Just as the pole was able to be seen on the CCTV, so too it would have been seen
by the other defendants as they approached the Carousel Street premises. Even if
the item had been picked up as they walked towards Carousel Street, they were
walking relatively slowly and in a group. The person holding the pole did not
appear to be attempting to conceal it in any way. In my view, it was established
beyond a reasonable doubt that one of the defendants was carrying the pole, and
that the other defendants would have been aware of this.

242 I reject as speculative the suggestion that the item seen in the CCTV footage
was, or might have been regarded by any of the other defendants as, anything other
than a weapon. I do not think there is any basis in the evidence for suggesting, for
example, that the item was an implement designed primarily for house-breaking.
Not only does it not appear to be an item designed for this use, the evidence
subsequently obtained from the Carousel Street premises suggests that bodily
force, rather than some house-breaking implement, was used to gain entry. I would
also reject as mere conjecture the suggestion that it might have been an implement
intended to assist in harvesting the cannabis they planned to steal, or a plastic or
toy bat designed only for threatening force. I would likewise also reject as
inherently implausible the suggestion that the item might have been discarded in
the moments between it being seen in the CCTV footage and the defendants’
arrival at the Carousel Street premises.
243 I do not, however, think it was indispensable to the prosecution case that one
of the men used the pole to inflict the fatal blow or blows. In my view, even if one
of the men used some other blunt instrument to inflict the fatal blow or blows, and
regardless of whether that blunt instrument was brought to the premises or located
within the premises, that would not make any significant difference to the analysis.
The position might have been otherwise had one of the defendants used a weapon
of an entirely different nature (that is, with a significantly greater risk of lethality),
such as a knife or gun. But that is not what occurred.
244 In any event, I am satisfied beyond reasonable doubt that the pole was used
to inflict the fatal blow or blows. In relation to the case against Mr Tenhoopen, he
made some admissions which assist in reaching that conclusion. In particular,
Ms McCormack and Ms Carson said that he described the occupant of the Carousel
Street premises being assaulted with an object. Whilst Ms Carson said he referred
to this object as a bat, this description is consistent with what the judge described
as the ‘pole like’ object seen in the CCTV footage.
245 However, I have reached that conclusion as against all defendants without
that evidence. In my view, the use of the pole in this way can be inferred from a
combination of the evidence to the effect that one of the men was seen carrying
the pole moments before entry to the Carousel Street premises; the pole was not
an item naturally suited to either use in forcing entry or in cutting or removing the
cannabis; the forensic evidence was to the effect that the fatal blow or blows to
Mr Gjabri’s head were the result of severe impact or impacts with a blunt
instrument consistent with the pole; and the pole was not located during subsequent
police searches of the Carousel Street premises, the surrounding streets and
elsewhere (such as where the defendants were residing).
246 It may be accepted that the apparent disposal of the pole was not critical to a
conclusion that it was used to inflict the fatal blow or blows, however it was a
relevant consideration. It can be accepted that the defendants would have been
-- 65 of 84 --
[2026] SASCA 71 S Doyle JA
62
more likely or careful to dispose of an item used in this way than some other item
that did not feature in the assault, and ultimate death, of Mr Gjabri.
247 Further, I reject the submission that the description of the item seen in the
CCTV footage as a ‘pole like’ object is somehow inconsistent with the forensic
evidence as to the cause of death. Whilst the forensic evidence included reference
to an object with a leading edge, the ultimate conclusion reached by Ms Charlwood
was that the cause of death was a blunt force trauma, with the injuries being
consistent with the use of a bat or pole. I do not understand the forensic evidence
to have involved a conclusion that the object in question necessarily had a square
edge. But even if it be assumed that the instrument used to inflict the fatal blow
or blows had a square edge, that is not inconsistent with a conclusion that it was
the item seen in the CCTV footage. The CCTV footage was not sufficiently clear
to determine whether that item had an edge. Whilst described as a ‘pole like’
object, it may be observed that this description was general enough to encompass
an object with an edge, whether it be a pole or some other similar looking item
such as a bat.
Scope of the agreement encompassed the possible use of violence
248 As a further aspect of their submission that the verdicts were unreasonable,
the appellants challenge McIntyre J’s finding beyond reasonable doubt that the
defendants’ agreement to steal cannabis encompassed the possible use of
violence.172
249 On my independent assessment of the evidence, this finding was warranted,
for essentially the reasons given by her Honour.173 In particular, the general
circumstances suggested a forceful approach to the theft of the cannabis. During
their travel to Para Vista, and then approach on foot, there was significant
opportunity for the defendants to discuss, or at least contemplate, the possibilities
of what might occur upon their entry into the Carousel Street premises. They
approached in a group of five. It would have been apparent to them that one of
their number was carrying the pole, being an item more suited to inflicting violence
than to forcing entry or assisting in some other way in stealing the cannabis. Given
that cannabis is a valuable commodity, they would have appreciated that there was
a risk that someone might be present at the Carousel Street premises. They would
have appreciated from the vehicle in the driveway that this was more than just a
possibility. They would have been on edge and full of adrenaline, and aware that
in entering the premises they would be entering an uncertain, and potentially
dangerous and volatile, situation. The evidence was that the defendants entered
the premises with force, and then acted with force once inside the premises.
172 Reasons [380].
173 Reasons [376]-[379].
-- 66 of 84 --
[2026] SASCA 71 S Doyle JA
63
250 These features of the evidence and circumstances, when considered in
combination, warranted a finding that the defendants’ agreement to steal cannabis
encompassed the possible use of violence.
251 I mentioned that the defendants approached as a group. Whilst the presence
of numbers was perhaps consistent with a hope that this might have been sufficient
to avoid the need for violence, it was more consistent with, indeed supportive of,
a realisation that force may be necessary.
252 In any event, even if some or all of the defendants hoped or anticipated that
they might be able to steal the cannabis without the use of violence, that did not
mean that they did not agree to its use as a possibility. As mentioned earlier in
these reasons, agreement to the contingent and even reluctant use of violence may
be sufficient for the purposes of liability pursuant to a JCE that ultimately involves
the use of force.174
Complaint of ‘no’ evidence for judge’s conclusions
253 Mr Mitchell sought permission to add a Ground 1A to the effect that there
was no evidence to support the judge’s conclusions that the pole seen in the CCTV
footage was the weapon used to kill Mr Gjabri, or that the defendants agreed to
use violence when stealing the cannabis, and hence no evidence upon which to
base the judge’s conviction for murder.175 Mr Mitchell argues that the judge
therefore erred as a matter of law, with the result that permission to appeal on this
ground is not required.
254 In my view, this proposed ground is misconceived. Whilst it may be true to
say that there was no evidence directly bearing on these issues, there was a
substantial body of circumstantial evidence from which appropriate inferences
might be drawn. It is not correct to say there was no evidence bearing on these
issues, let alone on the judge’s ultimate conclusion of guilt. To the extent that
there is an argument that the evidence was not sufficient to sustain her Honour’s
conclusions, that is a matter addressed through Mr Mitchell’s Ground 1 complaint
of an unreasonable verdict.
255 There being no prejudice to the respondent in Mr Mitchell raising the
complaint in Ground 1A, I would grant him permission to amend to include this
ground. However, I would dismiss the ground.
Indispensable intermediate facts
256 At times, some of the appellants framed their challenges to the
reasonableness of McIntyre J’s verdict by reference to various matters being
indispensable intermediate facts which her Honour was therefore required to find
beyond a reasonable doubt.

175 Carver Ground 1.3 involves a similarly framed complaint.

[2026] SASCA 71 S Doyle JA
64
257 Generally speaking, I do not think that the introduction of this terminology
was necessary or helpful. Insofar as the complaints were directed to elemental
aspects of the prosecution case (such as the existence of an agreement, the scope
of which encompassed the possibility of violence of the same general nature), there
was no need to resort to this terminology.
258 To the extent that this terminology was relevant to other findings (such as
that one of the defendants was carrying the pole as they approached Carousel
Street, that the other defendants would have been aware of this, that the pole was
used to inflict the fatal blow or blows, and that the defendants were present at, and
entered, the Carousel Street premises), this has already been addressed.
Failure to exclude alternative hypotheses
259 Various of the appellants argued that McIntyre J failed to consider or reject
hypotheses consistent with their innocence, either as a stand-alone ground176 or as
an aspect of their other grounds of appeal.
260 I have already mentioned the importance of taking a holistic rather than a
piecemeal approach to the evidence. I have also mentioned the need to be satisfied
beyond reasonable doubt that the defendant’s guilt is the only rational hypothesis.
As a corollary of this, it is necessary to exclude any hypothesis consistent with
innocence that is reasonably open. To be reasonably open, a hypothesis must be
based on more than mere conjecture or speculation; it must have some foundation
in the evidence.
261 I have already addressed, and excluded, several of the hypotheses consistent
with innocence advanced on appeal by the appellants. I have addressed and
rejected, for example, the possibility or hypothesis that the pole held by one of the
defendants as they approached the Carousel Street premises was (or might have
appeared to one of the other defendants to be) something other than a weapon. I
have addressed and rejected the hypothesis that one or more of the appellants did
not agree to the possibility of violence.
262 Other hypotheses advanced by the appellants were merely the converse of
certain findings made by the judge, and did not require explicit treatment by her
Honour beyond their rejection inherent in the findings that were made.
263 By way of example, Mr Rigney’s submissions on appeal included an
argument to the effect that McIntyre J erred in not excluding mere foresight of (as
opposed to agreement to) the possibility of violence in the course of stealing the
cannabis. I do not accept this submission. In her reasons, McIntyre J squarely
addressed and accepted the prosecution argument that the evidence established
beyond reasonable doubt that the defendants agreed to the possible use of force.177
As I have explained, this conclusion was soundly based in the evidence,
176 Rigney Ground 6.
177 Reasons [377]-[380].
-- 68 of 84 --
[2026] SASCA 71 S Doyle JA
65
particularly bearing in mind that even a contingent and reluctant agreement may
suffice. But importantly for present purposes, in reaching that conclusion, her
Honour plainly intended to, and did, reject as a reasonable possibility that any of
the defendants merely foresaw, rather than agreed to, this possibility of violence.
Her Honour’s reasons for concluding that an agreement was reached were
effectively her Honour’s reasons for rejecting mere foresight.
264 It has not been established that McIntyre J failed to consider, or unreasonably
rejected, any reasonable hypothesis consistent with innocence.
Verdicts not unreasonable
265 For the reasons given, the appellants’ complaints that their verdicts of guilty
of murder were unreasonable have not been made out. Having undertaken the
requisite independent assessment of the evidence, I am satisfied that the evidence,
considered holistically, established beyond reasonable doubt that each of them
participated in an agreement to steal cannabis which included the possibility of
violence.
266 I will address separately below the appellants’ complaints that, even if they
agreed to the possible use of violence: (i) this did not include violence of the same
general nature as that which was inflicted; and (ii) it was possible that the fatal
blow or blows were struck after the other defendants had left the premises and so
outside the scope of whatever had been agreed. Even though they form part of the
appellants’ complaints of unreasonable verdicts, they also include complaints
about the adequacy of the judge’s reasons.
267 I shall also address separately the appellants’ complaints that the judge’s
finding that the defendants agreed to the possible use of violence of the same
general type that occurred was inconsistent with: (i) Stein J’s finding in the Howell
matter to the effect that he did not agree the possible use of violence of the same
general nature as that which occurred and caused Mr Gjabri’s death; and (ii)
McIntyre J’s own finding that the appellants did not foresee that one of their
number might cause grievous bodily harm or death, with murderous intent.
Agreement to use violence of the ‘same general nature’
268 The appellants argue that even if they were party to an agreement to steal
cannabis that included the possible use of violence, this did not extend to the
possible use of violence of ‘the same general nature’ as that which occurred and
caused the death of Mr Gjabri.178
269 As explained earlier in these reasons, it was a requirement of the defendants’
convictions for constructive murder pursuant to a JCE that the intentional act of
violence which caused death was of ‘the same general nature’ as the violence
178 Rigney Ground 5, and encompassed within the unreasonable verdict ground advanced by the other
appellants.
-- 69 of 84 --
[2026] SASCA 71 S Doyle JA
66
which had been agreed as a possibility. As also explained earlier in these reasons,
this requirement was an aspect of the more general requirement of liability via a
JCE that the commission of the relevant crime fall within the scope of the
defendant’s agreement.
270 I have earlier canvassed a number of the authorities addressing this issue in
the context of cases involving the use of violence in connection with the
commission of some other foundational crime, such as robbery. In applying these
authorities to the facts in the Howell matter, I explained that in some cases it may
be appropriate to formulate the defendants’ agreement in terms of an agreement to
commit a robbery, involving any or whatever force is necessary. In other cases,
there might be a basis in the evidence for identifying some limit upon the violence
which has been agreed as a possibility, whether by reference to the nature or degree
of the violence or by reference to the purpose of the violence.
271 In the Howell matter, Stein J was not satisfied that Mr Howell agreed to the
possible use of violence intended to cause grievous bodily harm or death. Further,
Stein J accepted as a reasonable possibility that Howell only agreed to the
possibility of violence in order to subdue the occupant (and not aggressive violence
including striking the occupant to the head with sufficient force to fracture his
skull).
272 In the joint trial, on the other hand, McIntyre J found that the intentional act
or acts of violence that caused Mr Gjabri’s death was or were of the same general
type as that which the defendants in the joint trial had agreed was a possible part
of their joint enterprise to steal cannabis. In her Honour’s view, the defendants,
having agreed to the possible use of a weapon to assault any occupant of the
Carousel Street premises, had agreed to violence of the same general type as that
which occurred. The use of a blunt force instrument to strike Mr Gjabri to the head
with severe force (or force sufficient to fracture his skull) was violence of the same
general nature as what had been agreed as a possibility. Put differently, McIntyre J
did not allow for a reasonable possibility that there was a relevant limit upon the
violence which the defendants had agreed as a possibility. Her Honour did not,
for example, allow for a reasonable possibility that the defendants agreed only to
the possibility of force in order to subdue, and not the aggressive or gratuitous use
of force sufficient to fracture the occupant’s skull.
273 At times, some of the defendants sought to elevate their argument to one of
a formal inconsistency with the verdict in the Howell matter.179 This argument was
not pressed, and certainly not developed, in oral submissions. Indeed, it seemed
to me that the argument was abandoned. However, to the extent that it was pressed,
I do not think it has merit.
274 Taking a step back for a moment, all five defendants were initially charged
on the one information. Mr Howell’s defence of the case against him included an
179 Mitchell Ground 1.3; Rigney Ground 4; Tenhoopen Ground 9.
-- 70 of 84 --
[2026] SASCA 71 S Doyle JA
67
argument that he acted under duress, having been threatened by Mr Rigney.
Mr Rigney unsuccessfully applied for a separate trial, but ultimately the
prosecution filed a separate information against Mr Howell and he was tried
separately. As I have explained, there were differences in the evidence led at the
two trials. In particular, there was evidence in Mr Howell’s trial from his partner
and friends which was not led in the joint trial, and there was evidence in the joint
trial from Ms McCormack and Ms Carson which was not led in Mr Howell’s trial.
Indeed, whilst the prosecution did not seek to identify the person who inflicted the
fatal blow or blows in either trial, there was evidence in Mr Howell’s trial that
suggested that this person may have been Mr Rigney, whereas there was evidence
in the joint trial which, although not admissible against all defendants, suggested
that this person may have been Mr Howell.
275 It is accepted that where there is an inconsistency between two verdicts in the
same trial, and it cannot be explained or rationalised by some difference in the
evidence or other appropriate explanation, then this may justify a conclusion that
a conviction is unreasonable.180
276 In circumstances where there was different evidence in the trial against
Mr Howell, it is difficult to see how a relevant inconsistency could be made out.
That is particularly so in circumstances where Stein J’s reasoning in Mr Howell’s
matter was informed at least to some extent by the evidence admissible in that
matter, which did not feature in the joint trial. I refer in that respect to the evidence
from Mr Howell’s partner and friends as to Mr Howell’s distressed state both
immediately after the events of 8 October 2018 and upon subsequent media
coverage. Whilst there was similar evidence in relation to a couple of the
defendants in the joint trial, it does not appear to have had an equivalent influence
upon McIntyre J, even in relation to those defendants to whom it related. The
different evidence in relation to the knowledge and plans of the defendants in the
joint trial permitted differing conclusions as to the scope of the parties’ agreement,
and in particular the extent of the possible violence they agreed.
277 More fundamentally, even putting to one side the differences in the evidence
between the two trials, there is a difficulty in applying the principles governing
inconsistent verdicts as between verdicts in different trials.
278 At the very least, those principles have limited utility given the need to make
allowance not only for any differences in the evidence between the two trials, but
also the entitlement of different triers of fact to take a different view of the
180 MFA v The Queen (2002) 213 CLR 606 at [34] (Gleeson CJ, Hayne and Callinan JJ); R v H, GJ (2008)
102 SASR 82 at [23]-[27] (Kourakis J, Doyle CJ and White J agreeing); R v Neocleous (2017) 270 A
Crim R 262; [2017] SASCFC 162 at [149] (Doyle J, Peek J agreeing).

[2026] SASCA 71 S Doyle JA
68
witnesses from whom they hear evidence. This was the view of the English Court
of Appeal in R v Andrews-Weatherfoil Ltd.181
279 Although I have some reservations as to whether the principles governing
inconsistent verdicts apply at all when the verdicts relate to two separate trials, and
hence two separate triers of fact, it is not necessary for me to reach a concluded
view about this. It is not necessary because, ultimately, the appellants in the
present matter pitched their argument on this issue at the level that McIntyre J
erred: (i) in failing to address, and ultimately in failing to accept as a reasonable
possibility, the limitation upon the scope of the defendants’ agreement identified
by Stein J; and/or (ii) in holding that the severe blow(s) to Mr Gjabri’s head that
caused his death involved violence with a blunt force weapon which the defendants
agreed was a possibility.
280 It is fair to observe that McIntyre J’s reasons on this issue could have been
more detailed. The only place in which the judge squarely addressed the issue of
whether the scope of the defendants’ agreement included the possibility of
violence of the same general type as that which occurred was in paragraph [385].
As her Honour relevantly stated in that paragraph:
[385] … As outlined above, I am satisfied that the planned robbery included an agreement,
if necessary, to assault any occupant of the grow house with the weapon I find that
the defendants took with them. An assault with the weapon is an intentional act of
violence of the same general nature as that which killed Mr Gjabri.
281 Although succinct and conclusory in its terms, this extract from her Honour’s
reasons must be read in context. As the conclusion expressed is one that relates to
the scope of the defendants’ agreement, it must be read in the context of her
Honour’s earlier explanation for concluding that the agreement encompassed the
possibility of violence. In particular, her Honour’s reference to matters ‘outlined
above’ was presumably a reference to her reasons on this topic in paragraphs [377]-
[380]. Whilst her Honour did not say so in terms, it is apparent from these passages
from her reasons that she was not satisfied that there was any basis in the evidence
at the joint trial for relevantly confining the scope of the violence that was agreed
as a possibility, or for otherwise concluding that the violence which did occur was
not of the same general type as that which had been agreed as a possibility. Her
Honour was apparently not satisfied that there was any basis for confining the
agreement to the possibility of violence which was for the purpose of subduing the
occupant, as opposed to aggressively striking him with sufficient force to fracture
his skull.
282 The issue is ultimately an impressionistic one rather than one that is
susceptible of detailed or rigorous analysis. Having undertaken an independent
assessment of the evidence in the joint trial, the issue is finely balanced. In my
181 R v Andrews-Weatherfoil Ltd [1972] 1 WLR 118 at 125-126 (Everleigh J); approved by the House of
Lords in R v Shannon [1975] AC 717; and cited with approval by the High Court in MacKenzie v The
Queen (1996) 190 CLR 346 at 366 (Gaudron, Gummow and Kirby JJ).

[2026] SASCA 71 S Doyle JA
69
view, even though I have accepted that Stein J’s different view was ‘open’ on the
evidence in the Howell matter, it was nevertheless also ‘open’ to McIntyre J to
conclude that the defendants in the joint trial agreed to the possibility of violence
of the same general nature as that which caused Mr Gjabri’s death. Even if
relatively slight, McIntyre J had some advantage over this Court. She had the
advantage of seeing and hearing the witnesses give evidence, as well as
considering the evidence more generally, in the context and atmosphere of the trial
as it unfolded. Whilst sometimes difficult to identify and describe, this advantage
was nevertheless real. Bearing in mind this advantage, I am not satisfied, on my
independent assessment of the evidence, that it can be said that her Honour must
have, as distinct from might have, entertained a reasonable doubt about the
defendants’ guilt of murder.
283 As I have explained, the defendants travelled in numbers and with one of
them carrying an item which might be used as a weapon. They would have
appreciated that there may well be someone present in the premises they were
about to enter, and that force might have been necessary. They would have
appreciated that they were about to encounter an uncertain, and potentially volatile
and dangerous, situation. Whilst some of them may have been reluctant for
significant force to be used, I am satisfied that it was open to conclude, as
McIntyre J did, that the defendants must have anticipated and agreed to the
possibility that one of their number might strike any occupant who they came
across with sufficient force to cause serious harm, and hence anticipated and
agreed to violence of the same general nature as that which occurred and caused
death. Indeed, this conclusion would be consistent with the caution that I have
earlier in these reasons suggested will be appropriate when considering or allowing
for the possibility of some limit upon the nature of violence which has been agreed
as a possible incident of the JCE.
284 For these reasons, I would reject the appellants’ challenges to the judge’s
reasoning and conclusion to the effect that they agreed to violence of the same
general nature as that which caused Mr Gjabri’s death, and the appellants’ related
contention that the verdicts were unreasonable on this account.
Inconsistency with rejection of extended joint criminal enterprise
285 The complaints raised by the appellants include a complaint that McIntyre J’s
conclusion that the defendants’ agreement encompassed violence of the same
general nature as that which caused Mr Gjabri’s death was inconsistent with her
own rejection of the prosecution case of common law murder by reason of an
EJCE.182
286 As recounted earlier in summarising McIntyre J’s operative reasoning, her
Honour rejected the prosecution case on common law murder by reason of an
EJCE in paragraph [384]. Her Honour did so on the basis that she was not satisfied
182 Mitchell Ground 2; Tenhoopen Ground 7.
-- 73 of 84 --
[2026] SASCA 71 S Doyle JA
70
beyond reasonable doubt that the defendants foresaw or contemplated that one or
more of their number might use a weapon to assault Mr Gjabri with the intention
of causing him death or grievous bodily harm. In reaching this conclusion, the
judge relied on the evidence that Mr Tenhoopen and Mr Carver were shocked and
distressed when they found out about Mr Gjabri’s death, and her acceptance that it
was unnecessary and indeed counterproductive for the defendants to kill or inflict
serious harm to any occupant of the house in order to steal the cannabis.
287 It is to be accepted that there is a fine distinction between this conclusion and
McIntyre J’s conclusion in the very next paragraph of her reasons to the effect that
the violence that occurred was of the same general nature as that which was agreed
as a possible incident of the defendants’ plan to steal cannabis. However, the
distinction is nonetheless clear. Putting to one side the distinction between the
violence being agreed as a possibility (for JCE) and merely being foreseen as a
possibility (for EJCE), there is a distinction between violence of the same general
nature as the intentional act of violence that killed Mr Gjabri (for constructive
murder) and an act intended to cause death or grievous bodily harm (for common
law murder). Whatever the precise limits of the notion of violence of ‘the same
general nature’ as the act which killed Mr Gjabri, it encompasses, in the sense that
it includes or extends to, a lower level of violence than an act intended to cause
death or grievous bodily harm.
288 It follows that there is no inconsistency between McIntyre J’s conclusions as
to the level of violence agreed or foreseen as a possibility. On her Honour’s
approach, it was proved that the defendants agreed the possibility of violence of
the same general nature as that which occurred, but did not foresee the possibility
of violence perpetrated with an intent to cause grievous bodily harm or death. I
have explained why, in my view, it was open on the evidence for her Honour to
find the former. But having reached this finding, there was no logical difficulty
with her Honour nevertheless rejecting the prosecution case on common law
murder by EJCE.
289 Implicit in this conclusion is my rejection of a related submission advanced
on behalf of Mr Mitchell. On appeal, Mr Mitchell argued that liability for
constructive murder pursuant to a JCE required that the prosecution establish not
only (i) that Mr Mitchell agreed the possibility of violence of the same general
nature as that which caused Mr Gjabri’s death, but also (ii) that he contemplated
(in the sense that he agreed to the possibility of) violence of a type that might cause
death or grievous bodily harm.
290 If, as Mr Mitchell argued, it was necessary for the prosecution to establish
(ii), then there may well have been force in the submission that there was a tension,
if not inconsistency, between a conclusion that Mr Mitchell did have the
contemplation necessary to establish (ii), but did not have the foresight necessary
for common law murder by EJCE.
-- 74 of 84 --
[2026] SASCA 71 S Doyle JA
71
291 However, I do not accept that (ii) is a requirement of liability for constructive
murder pursuant to a JCE. The High Court in Mitchell did not suggest it was a
requirement, and no authority was cited to this Court for the submission that it was
a requirement. Certainly the judge did not treat it as a requirement and thus did
not make any finding that was inconsistent with her basis for rejecting common
law murder by EJCE.
292 Finally, I do not consider that there is any merit in Mr Tenhoopen’s related
complaint about the judge’s reference to the defendants being party to an
agreement ‘if necessary’ to assault any occupant with the weapon they were
carrying. Her Honour’s reference to an assault ‘if necessary’ was intended merely
to emphasise the contingent nature of the violence to which they had agreed. They
had not agreed that violence would be used; rather, they had agreed that violence
was a possible incident of their plan; and they had agreed that violence would be
used if it became necessary. Violence would not have been necessary if, for
example, it turned out there was no-one at the premises, or any occupant(s) fled
from the premises.
293 Understood in this way, the reference to the defendants agreeing to violence
‘if necessary’ did not involve any reliance upon a mere contemplation or mere
foresight of violence. Her Honour was plainly alive to, and observed, the
sometimes fine, but nevertheless important, difference between foresight (for the
purposes of EJCE) and agreement (for the purposes of JCE).
Agreement was still on foot when fatal blow was struck
294 The next complaint to be addressed is an argument that McIntyre J failed to
address, or erred in rejecting, the possibility that the defendants’ agreement or joint
enterprise was no longer on foot when the fatal blow was inflicted.183 The argument
was framed as an aspect of both a complaint of an unreasonable verdict and a
complaint of inadequate reasons.
295 So far as Mr Tenhoopen was concerned, this argument was founded upon his
out of court statements to the effect that Mr Howell went back inside the Carousel
Street premises to ‘finish off’ Mr Gjabri after they had stolen the cannabis and so
after any joint enterprise had been completed. So far as the other appellants
pursuing this ground were concerned, the argument was founded upon the more
general or abstract possibility that one of the other defendants acted in this way.
They relied upon the inability for the prosecution to identify the precise timing of
fatal blow, and in particular whether it occurred before or while the cannabis was
being cut, bagged and removed, or whether it occurred after those tasks had been
completed.

72
296 In addressing Mr Tenhoopen’s argument at trial, McIntyre J reasoned as
follows:
[301] Ms McCormack’s evidence about “the man” looking out of a window is difficult to
assess. Ms McCormack said that:
When they returned to Adelaide, Tenhoopen told her that when he and the
others left the house that evening, he saw the male looking through the
window and that “[JPH] finished him off”. I note in this context Ms
McCormack’s concession in cross-examination that, at the first trial when her
memory was better, she said that Tenhoopen told her that “[JPH] went back
into the house and finished him off”.
[302] Most of the windows were covered with plastic which did not appear to have been
disturbed. However, the kitchen and laundry windows only had vertical blinds, so it
is possible that Mr Gjabri looked out of one or other of those windows as the
intruders were departing.184 The forensic evidence is that Mr Gjabri was alive for at
least an hour after the head injury was inflicted. The crime scene indicates that he
moved around the house for a period of time. It is unlikely that this occurred whilst
the theft was taking place and, in any event, his blood was found on top of the
cannabis debris.
[303] I note the submission made on behalf of Tenhoopen that this of itself ought to be a
basis for his acquittal. I do not agree. First, the plan to steal cannabis was still on
foot at the time this is said to have occurred. Second, whilst this evidence is
admissible as against Tenhoopen in respect of his involvement in the theft of
cannabis, in so far as it represents an exculpatory statement by Tenhoopen as to his
involvement in Mr Gjabri’s death, it is inadmissible hearsay.
297 In my view, the appellants’ argument should be rejected.
298 It is to be acknowledged that the judge appears to have erred in two respects
in her treatment of Ms McCormack’s evidence to the effect that Mr Tenhoopen
told her that, as they were leaving the Carousel premises, he saw the occupant
looking out the window and that Mr Howell went back inside to ‘finish him off’.
299 First, it appears her Honour misunderstood the evidence about the covering
of the windows,185 and that it would have been possible for Mr Gjabri to have been
looking out through the windows at the front of the house. But it does not seem
that this error was of any consequence, given that her Honour expressly allowed
for the possibility that Mr Gjabri might have been seen through one of the kitchen
or laundry windows.
300 Secondly, it appears that her Honour erred in describing the relevant aspect
of Ms McCormack’s evidence as ‘inadmissible’ hearsay.186 Even though hearsay
in nature, this evidence was admissible as part of a mixed statement.
McCormack’s evidence of what Mr Tenhooopen told her was led by the
184 Exhibit P3.

186 Tenhoopen Ground 2.

prosecution on the basis that it included admissions by Mr Tenhoopen. His
statements having been led on that basis, the entirety of those statements, including
any exculpatory aspects, were admissible in the case against him.187 Whilst the
judge was entitled to give the exculpatory aspect of this evidence little or no
weight, her Honour was not entitled to ignore it as inadmissible. If her Honour did
ignore this evidence, then her Honour erred in doing so.
301 However, any error in this respect was, on the face of her Honour’s reasons,
of no consequence. It was of no consequence because even if this error, like the
other error, might have influenced her Honour’s apparent disinclination to accept
that it was possible that Mr Howell did go back inside to ‘finish off’ Mr Gjabri,
her Honour nevertheless considered that possibility. She considered it, and
concluded (paragraph [303]) that it was not an obstacle to the prosecution case. It
was not an obstacle because if it occurred, it occurred while the plan to steal
cannabis was still on foot.
302 For these reasons, any error in the treatment of Ms McCormack’s evidence
was not realistically capable of affecting the judge’s reasoning to her verdict of
guilty. It was not material in the relevant sense.
303 Further, I agree with the judge’s conclusion in paragraph [303] that, even if
it be accepted that Mr Howell (or one of the other defendants) went back inside
the Carousel Street house and ‘finished off’ Mr Gjabri, this nevertheless occurred
while the plant to steal the cannabis was still on foot.
304 The first point to make is that it seems unlikely on the evidence that this
occurred. Even though there was some evidence in the case against Mr Tenhoopen
that this might have occurred (through his statement to Ms McCormack to this
effect), the weight to be attached to this evidence fell to be assessed in a context
that included the evidence that Mr Tenhoopen told Mr W that Mr Gjabri was hit
over the head during the initial struggle with him following the defendants’ entry
into the Carousel Street premises. As against the other defendants there was no
basis in the evidence to suggest the possibility that the fatal blow was inflicted after
they had removed the cannabis from the house. I am not persuaded that it was
reasonably possible that the fatal blow was inflicted in the manner contended.
305 But more fundamentally, even if the fatal blow was inflicted after the
cannabis was removed from the Carousel Street premises, the plan to steal the
cannabis was still on foot. Even on Mr Tenhoopen’s version of events, he and the
other defendants were still in the driveway when Mr Howell went back inside.
Even if it was unnecessary at that point for Mr Howell to return inside and kill
Mr Gjabri, the plan was still on foot. The plan remained on foot at least until they
left the Carousel Street premises together in Mr Gjabri’s car, with the cannabis in
the boot of that vehicle. The suggestion that the plan somehow came to an end

JJ), [59] (Edelman J).

74
once the cannabis was out of the house, but while they were still in the driveway
of that house waiting to leave in Mr Gjabri’s car, involves an artificially narrow
view of the plan.
306 The appellants argued that once the cannabis had been removed, the robbery
was legally complete. I do not agree. Under s 137 of the CLCA, robbery
encompasses the use of force at the time of, or immediately before or after, the
theft. In my view, violence which occurred prior to the defendants leaving in
Mr Gjabri’s car was still part of the robbery. But even if it was possible that one
of the defendants inflicted the fatal blow after the offence was legally complete, it
does not follow that the defendants’ agreement or plan was no longer on foot. In
my view, that agreement or plan continued at least until they had left the Carousel
Street premises in Mr Gjabri’s vehicle, and probably until they had divided up the
cannabis back in Murray Bridge.
307 For these reasons, I am satisfied that the defendants’ agreement or plan was
still on foot at the time the fatal blow or blows were struck. Whilst her Honour
only directly addressed this issue in the context of the case against Mr Tenhoopen,
and even then did so in a succinct if not conclusory manner, her Honour’s reasons
were adequate. Read as a whole, her Honour made properly reasoned and
supported findings which necessarily entailed a conclusion that the defendants’
agreement or plan was still on foot at the time when the fatal blow was struck.
308 For completeness, I add two observations.
309 The first is that I do not think it alters the analysis to describe the possibility
that Mr Howell went back inside to ‘finish off’ Mr Gjabri as a possibility that
Mr Howell was acting on a ‘frolic of his own’ and therefore outside of the scope
of any plan or agreement. Even assuming it was reasonably possible that
Mr Howell went back inside and struck Mr Gjabri to the head with sufficient force
to fracture his skull, the issue remains whether this involved violence of the same
general nature as that which had been agreed as an incident of the robbery. Even
if this might be described as violence which was severe and gratuitous (in the sense
it went beyond what was strictly necessary to steal the cannabis), the issue remains
whether it was reasonably possible to discern some basis for a relevant limit upon
the nature or level of the violence to be used. Whilst Stein J found a relevant
limitation on the evidence in the trial against Mr Howell, McIntyre J was not
persuaded that there was a basis for any such limit. Whilst accepting that the
defendants had not foreseen (let alone agreed) to the use of force intended to cause
grievous bodily harm or death, her Honour was not prepared to infer a limitation
which would have taken the violence used outside of the general nature of the
violence which it had been agreed might be used.
310 Secondly, I do not accept that there was any basis in the evidence for a
submission that any of the defendants withdrew from their agreement or plan prior
to the infliction of the fatal blow. It was thus not a matter which it was necessary
for McIntyre J to address in her reasons.

Inadequate reasons
311 Each of the appellants raise complaints about the adequacy of McIntyre J’s
reasons. Mr Carver makes a general complaint as to the adequacy of the judge’s
reasons in support of her conclusion that he was party to an agreement the scope
of which encompassed violence.188 Each of the appellants make complaints about
the adequacy of the judge’s reasons on the topic of whether the agreement was still
on foot when fatal blow was inflicted.189
312 The appellants’ complaints about the inadequacy of the judge’s reasons relate
largely, if not entirely, to matters which I have already addressed in the context of
my consideration of the appellants’ challenge to the judge’s verdicts on the ground
they are unreasonable. Particularly in circumstances where they were not
emphasised in the appellants’ submissions, I consider that the appellants’
complaints of inadequacy in the judge’s reasons have been sufficiently addressed.
313 As I have earlier acknowledged, the judge’s reasons may have benefited from
a more detailed treatment of some issues. However, read as a whole, her Honour’s
reasons adequately addressed the issues in dispute, and set out the key steps in her
reasoning to guilt. I am not persuaded that any of the complaints of inadequacy
have been made out.
Use of DNA evidence against Mitchell
314 Mr Mitchell contends that McIntyre J erred in her treatment of the evidence
about the DNA profile obtained from a pair of secateurs located in the Carousel
Street premises.190
315 The judge addressed this evidence in detail in her reasons.191 As the judge
explained, the DNA profile obtained from the secateurs gave strong support for
Mr Mitchell as a contributor to that profile. Mr Mitchell’s complaint on appeal
appears to be that the judge failed to give adequate consideration to the possibility
that this may have been a result of secondary transfer, via one of the other
defendants, and that the judge ultimately erred in excluding this as a possible
explanation for Mr Mitchell’s DNA on the secateurs.
316 There are two difficulties with Mr Mitchell’s submissions on this ground of
appeal. The first is that the judge plainly did address the issue of secondary
transfer.192 Her Honour referred to the expert evidence to the effect that this was
possible. However, her Honour considered that this explanation for Mr Mitchell’s
DNA, whilst possible, was not likely. The second is that, as the judge
acknowledged, there was no need for her to exclude secondary transfer as a
reasonable possibility. This case was distinguishable from Fitzgerald v The

Queen,193 where it was necessary to exclude secondary transfer as a reasonable
possibility. As McIntyre J explained, whilst Mr Mitchell’s connection with the
secateurs was circumstantial evidence probative of his entry inside the Carousel
Street premises, neither his connection with the secateurs, nor even his entry inside
the Carousel Street, was an indispensable intermediate fact which required proof
beyond reasonable doubt.
317 Mr Mitchell’s challenge to the judge’s treatment of the evidence in relation
to the DNA profile obtained from the secateurs has not been made out.
Other Tenhoopen grounds
318 Mr Tenhoopen raised some discrete matters on appeal.
319 I have already addressed two of these, being his Ground 2 complaint about
the judge’s error in treating an inculpatory aspect of Ms McCormack’s evidence
as inadmissible hearsay, and his Ground 5 complaint about the judge
misunderstanding an aspect of the evidence relating to the window coverings at
the front of the Carousel Street premises.
320 In Ground 4,194 Mr Tenhoopen complains that the judge misused the evidence
of an intercepted telephone conversation in which Mr Tenhoopen said to
Ms McCormack ‘oh well, shit happens hey, sometimes you have to go in and
fucking hurt someone too much’. As mentioned earlier, the judge treated this as
an admission of Mr Tenhoopen’s awareness of events on the night of the cannabis
theft, including Mr Gjabri being hurt,195 and ultimately an admission of his
involvement in that theft.196
321 Although not challenging the judge’s use of this telephone intercept evidence
in this way, Mr Tenhoopen argues on appeal that her Honour went further and used
it as an admission of Mr Tenhoopen’s agreement to use force or violence.
322 I do not accept that the judge used the evidence in this way. When directly
considering the evidence in paragraphs [348] and [350], her Honour expressly
confined the admission in the manner described above. Consistently with this, the
judge later made reference to ‘the listening device evidence’ when finding that
Mr Tenhoopen was party to the plan to steal cannabis.197
323 Mr Tenhoopen emphasises a further reference to this evidence in paragraph
[376] of McIntyre J’s reasons. In moving from her consideration of the existence
of an agreement to steal cannabis, to a consideration of whether that agreement
included the use of force, her Honour commenced as follows:
193 Fitzgerald v The Queen (2014) 88 ALJR 779.
194 Tenhoopen Ground 4.

[376] The defendants intended to steal cannabis; did they intend to threaten or use force?
There is no direct evidence from any of the defendants as to their intentions. As
against Tenhoopen alone I note his admissions to the use of force to Ms McCormack,
Ms Carson and Mr W and his comment on the covert listening device. There is not
evidence in respect of the other defendants. The intentions of all four defendants
and [Mr Howell] must be inferred from the surrounding circumstances.
(emphasis added)
324 Read in context, I do not think her Honour used the listening device evidence
as an admission of Mr Tenhoopen’s agreement to use force or violence. Her
Honour was merely introducing her consideration of the topic by noting
Mr Tenhoopen had admitted using violence in his statements to Ms McCormack,
Ms Carson and Mr W, and had made a comment about the use of violence in the
listening device evidence. Her reference to Mr Tenhoopen’s ‘comment’ about the
use of force, as opposed to an ‘admission’ about the use of force, on the listening
device is consistent with her Honour appreciating, as she had earlier, that in this
conversation Mr Tenhoopen only admitted awareness of the violence, rather than
involvement in it or agreement to use it. But even if the judge had overlooked this
distinction, and treated the listening device evidence as including an admission
about the use of force, that would not take the matter very far for two reasons.
325 The first is that Mr Tenhoopen had made other admissions about the use of
force in his conversations with Ms McCormack, Ms Carson and Mr W. The
second is that the judge plainly recognised that even though the use of (some
limited) force by Mr Tenhoopen was relevant to what he and others had agreed,
the fact and extent of any agreement to use force fell to be ‘inferred from the
surrounding circumstances’. In considering those surrounding circumstances, her
Honour did not draw upon any suggested admission by Mr Tenhoopen that he had
agreed to the use of force.
326 In Ground 6,198 Mr Tenhoopen contends that the judge erred in accepting the
evidence of Mr W without warning herself about the risk of his evidence lacking
credibility or reliability.
327 As recounted earlier, Mr W was a cell mate of Mr Tenhoopen in late 2018.
He gave evidence of conversations he had with Mr Tenhoopen in which
Mr Tenhoopen made various statements about the events during the night of
8 October 2018. The judge addressed this evidence in some detail,199 before
ultimately accepting Mr W’s evidence to the effect that Mr Tenhoopen had made
admissions to him about not only his involvement in the theft of cannabis, but also
the use of violence in that theft.200 As to the latter, the admissions to Mr W included
statements that there had been a struggle with the occupant in a doorway, that the
occupant had been hit over the head, and that the occupant was then taken to
198 Tenhoopen Ground 6.

78
another room where the group took turns watching him while the others collected
the drugs. The admissions did not include any reference to who had struck the
blow to the occupant’s head, or what was used to strike that blow.
328 In closing addresses at trial, counsel for Mr Tenhoopen submitted that the
judge should be mindful of McHugh J’s observations in Pollitt v The Queen,201
about the danger of relying upon the evidence of a prison informer where that
evidence is not corroborated by other evidence tending to connect the defendant
with the offence charged.
329 In her reasons for judgment, McIntyre J did not address this submission or
danger in terms. Early in her reasons, when addressing her approach to the
witnesses in the trial generally, the judge did give herself the following direction:
[31] In making findings of fact, I must rely upon the evidence given by the witnesses and
the evidence contained in the exhibits. I must apply my common sense; I have
reminded myself of the usual directions given in this state to juries concerning the
proper approach to assess the various witnesses who gave evidence, their credibility
and reliability.
330 Given the submission that had been made in Mr Tenhoopen’s closing
address, the Director contends that her Honour’s reference to the proper approach
to be taken in assessing ‘various witnesses’ should be understood as including
reference to Mr W’s evidence. Whilst that may be so, it is not clearly so. It would
have been better had the judge made explicit reference to the caution which was
appropriate in considering the evidence of Mr W.
331 However, ultimately, the issue is whether there has been a miscarriage of
justice. Given that this was a trial by judge alone, there may be no miscarriage of
justice if the judge’s reasons demonstrate an awareness of the need for caution in
assessing Mr W’s evidence, and that an appropriately cautious approach was taken.
332 In that regard, there are several significant aspects of her Honour’s treatment
of Mr W’s evidence. When introducing his evidence, she twice made reference to
his status as a prisoner.202 She explicitly stated that it was ‘important in this context
to consider whether Mr W is a credible and reliable witness’.203 After summarising
the effect of Mr W’s evidence about what Mr Tenhoopen said to him, McIntyre J
described him as giving his evidence in a straightforward manner and not shying
away from his ‘somewhat extensive criminal history’.204 Her Honour made
reference to Mr W having ‘denied making up the account given to him by
201 Pollitt v The Queen (1992) 174 CLR 558 at 614 (McHugh J); see also at 585-586 (Brennan J), 588
(Deane J) and 599 (Dawson and Gaudron JJ).

79
Tenhoopen because he had a sentencing matter coming up’. The judge added that
there was no evidence that Mr W had been offered any reward for his evidence.205
333 Over the next three paragraphs, the judge considering the extent to which
matters about which Mr W gave evidence accorded with the other evidence that
the judge had heard. She identified several aspects of his evidence which were
consistent with matters that had been ‘independently established’ by the evidence
about the crime scene, or that Mr W could only have obtained from Mr Tenhoopen.
Her Honour also noted the ‘significant similarity’ between the evidence of Mr W
and the evidence of Ms McCormack and Ms Carson about what they were told by
Mr Tenhoopen. Her Honour acknowledged some aspects of Mr W’s evidence that
were inconsistent with other evidence, but was satisfied that these were indicative
of him being mistaken rather than him fabricating his evidence.
334 It was only after this detailed treatment of Mr W’s evidence that her Honour
accepted that his evidence was generally truthful and reliable.206
335 In the circumstances I have described, it is plain that the judge was aware of,
and observed, the need for caution in considering the credibility and reliability of
Mr W’s evidence. Her Honour identified and considered the sources of particular
risk or danger when considering the credibility and reliability of his evidence, and
she identified and considered the extent to which his evidence was corroborated
by, or otherwise consistent with, other aspects of the evidence. In those
circumstances, I do not accept that the judge’s failure to expressly acknowledge
the submission of Mr Tenhoopen’s trial counsel about the dangers associated with
a prison informer’s evidence occasioned any miscarriage.
336 No error has been identified in her Honour’s approach to Mr W’s evidence.
There is no reason to think that she overlooked, or erred in rejecting, the possibility
that Mr W might not have accurately understood or recalled some aspects of what
Mr Tenhoopen said, including the extent to which he might have been merely
describing things that he had been told by others.
337 Finally, and in any event, the judge only relied upon Mr W’s evidence as
establishing admissions by Mr Tenhoopen as to his involvement in the theft of the
cannabis, and as to use of force in the course of that theft. Her Honour did not
suggest that Mr W’s evidence included any admission by Mr Tenhoopen that he
had used violence, or that he had agreed to the use of violence. Whilst the
admissions made to Mr W formed part of the context in which the judge came to
consider the latter issue,207 they did not add much to the similar admissions he had
made to Ms McCormack and Ms Carson, and did not directly inform her Honour’s
reasoning to the effect that an agreement to use violence could be inferred from
the surrounding circumstances.

338 I am not satisfied that the complaint of a material miscarriage of justice in
Ground 6 of Mr Tenhoopen’s appeal has been made out.
Conclusion
339 For the reasons set out, I would grant the appellants permission to appeal on
all grounds where that is necessary. However, I am not satisfied that any of the
grounds of appeal have been made out. I would therefore dismiss the appeals
brought by Mr Mitchell, Mr Carver, Mr Rigney and Mr Tenhoopen.
