APPEAL AND NEW TRIAL - NEW TRIAL - IN GENERAL AND PARTICULAR
GROUNDS - PARTICULAR GROUNDS - MISDIRECTION OR NON-
DIRECTION - JUDGE'S SUMMING UP
Appeal against conviction.
A jury found the applicant guilty of aggravated causing serious harm with intent to cause serious
harm, contrary to s 23(1) of the Criminal Law Consolidation Act 1935 (‘the CLCA’).
The victim attended the home of the applicant following exchanges of text messages in relation to a
drug debt owed by the applicant. The applicant and victim had a violent altercation in which the
applicant stabbed the victim. At trial the applicant contended that the stabbing occurred in the course
of a home invasion within s 15C(2) of the Act.
On appeal the applicant contended that a miscarriage of justice arose from the trial judge’s
unbalanced direction to the jury in relation to the statutory “home invasion defence” under s 15C(2)
of the CLCA. The applicant contended that the trial judge failed to put to the jury that his drug
possession did not give rise to the offending, because the altercation occurred as the result of his
failure to repay a drug debt which was not “criminal misconduct”, as defined.
The Court held (refusing permission to appeal):
1. Though it was suggested that the failure of the appellant to give evidence may have rendered
it unnecessary for the trial judge to leave the statutory “home invasion defence” to the jury,
that she did so was both understandable and entirely appropriate.
2. It is not reasonably arguable that the direction on s15C(2)(b) was unbalanced.
-- 1 of 14 --
3. The trial judge was not required to leave for the jury a view of the facts which was untenable.
4. The applicant's approach ignored the breadth of the s 15C(2)(b) exclusion. The altercation
and the offending resulted from the applicant’s drug possession. The appellant’s drug
possession could not be divorced from the debt owed in respect of that possession. They
remained inextricably linked. That is to say, the drug possession may have given rise to the
threat or perceived threat.

WALTERS v THE KING
[2023] SASCA 133
Court of Appeal – Criminal: Livesey P and David JA
THE COURT:
Introduction
1 Following a trial, on 17 July 2023 a jury unanimously found the applicant
guilty of aggravated causing serious harm with intent to cause serious harm,
contrary to s 23(1) of the Criminal Law Consolidation Act 1935 (SA) (the CLCA).
2 In broad terms, the prosecution case was that the applicant caused serious
harm to Mr Gavin Greene, intending to cause him serious harm, when he stabbed
him a number of times with a knife on 2 January 2021 at Mount Gambier. The
aggravating feature was the applicant’s use of an offensive weapon.
3 It is common ground that Mr Greene had supplied the applicant with
methylamphetamine some weeks before, and the applicant had refused to pay
Mr Greene, whether in cash or kind. On 2 January 2021 Mr Greene attended at
the applicant’s home unit in connection with this drug debt, after the applicant and
Mr Greene had exchanged threatening text messages. In one of these messages
the applicant goaded Mr Greene about coming around to his unit. Soon after
Mr Greene’s arrival, there was a violent altercation inside the unit, during which
the applicant stabbed Mr Greene.
4 The applicant relied on self-defence. There was an issue about whether the
applicant’s response to any threat or perceived threat was excessive. Although the
applicant did not give evidence, the trial judge directed the jury regarding s 15C of
the CLCA, which permits a defendant to set up self-defence where the defendant’s
disproportionate response occurs in the context of a “home invasion”, that is, the
“home invasion defence”.
Permission to appeal and the disposition of the application
5 By amended grounds dated 27 October 2023, the applicant seeks permission
to appeal on the following proposed grounds:
There was a miscarriage of justice as a result of inadequate directions to the jury by the
learned Trial Judge with respect to:
(a) Section 15C(2)(b) of the Criminal Law Consolidation Act, and;
(b) Section 15C(2)(c) of the Criminal Law Consolidation Act.

6 The respondent contended that the application for permission to appeal is not
reasonably arguable. On 13 November 2023 the question of permission was
referred for argument as on appeal before two judges.1
7 During the hearing on 8 December 2023, the applicant abandoned proposed
appeal ground (b). For the following reasons, permission to appeal should be
refused.
The circumstances of the offending
8 By the time of the alleged offending, Mr Greene had for some time been
demanding that the applicant pay him for a “scoop” of methylamphetamine, and
he had become angry about the applicant’s refusal to do so. Text messages
exchanged between the two men regarding this drug debt between New Year’s Eve
on 31 December 2020 and 2 January 2021 became increasingly hostile and
threatening. For example, Exhibit P1 included the following exchange:
Greene: When exactly am I going to get the scoop back [?] you owe me Walters… it’s
2 n a half months already...
Applicant: When I get more
Greene: What? you haven’t had any in the last 2 n half months??
Applicant: Grow up
Greene: Really? Walters… U are a fried fucking unit. Next time I see U cunt, I’m
going to kick the fuck out of you.
9 During 1 January 2021, the applicant messaged Mr Greene as follows:
Applicant: I can’t be fried if I’m not on.
Happy New Year.
I am home.
I am sorry, do you need to wash your vagina m
Come on you fucking COWARD, come and say shit to my face, you Yellow
Cunt.
10 The following day, on 2 January 2021 at 4.23 pm, around half an hour before
the altercation, the applicant messaged Mr Greene in these terms:
Applicant: Afternoon COWARD.
Don’t forget to change your tampon. Ya yellow cumt.
Cunt.

And ya scoop, shove that up your arse.
11 Mr Greene gave evidence that he walked 500 metres to the applicant’s home
to talk to the applicant about what was owed. He said that when he got to the front
door, he knocked on the screen door which was closed. The front door was open.
Mr Greene said that he could see the applicant inside the unit. The applicant got
up and started yelling abuse at Mr Greene. He said, “Do you want to fuck me with,
you cunt?” Mr Greene said the applicant came to the screen door and put his foot
through it.
12 After the applicant opened the screen door, Mr Greene said the applicant
started swinging punches to his neck and abdomen. This occurred just inside the
applicant’s unit. Mr Greene described around 15 strikes from the applicant.
During the altercation, Mr Greene noticed blood. Mr Greene stopped and walked
outside. Initially Mr Greene thought it was the applicant’s blood. He said to the
applicant, “You better go and get yourself checked out”, to which the applicant
replied, “I think you’d better go and get yourself checked out”, after which
Mr Greene lost consciousness and collapsed.
13 The applicant had stabbed Mr Greene in the neck and stomach with a knife.
In MFI P11, the transcript of a triple-zero call, the applicant is recorded as having
admitted that he had stabbed Mr Greene. The applicant told the operator that he
was protecting himself. Later, the blade portion of the knife used by the applicant
was found on a verandah just outside his home unit.
Section 15C of the CLCA
14 In so far as it was suggested that the applicant’s response was not
proportionate to the threat posed by Mr Greene, the applicant relied upon s 15C of
the CLCA, by which self-defence which is, objectively, not reasonably
proportionate is permitted in connection with a home invasion:
15C—Requirement of reasonable proportionality not to apply in case of an innocent
defence against home invasion
(1) This section applies where—
(a) a relevant defence would have been available to the defendant if the
defendant's conduct had been (objectively) reasonably proportionate to the
threat that the defendant genuinely believed to exist (the perceived threat);
and
(b) the victim was not a police officer acting in the course of his or her duties.
(2) In a case to which this section applies, the defendant is entitled to the benefit of the
relevant defence even though the defendant's conduct was not (objectively)
reasonably proportionate to the perceived threat if the defendant establishes, on the
balance of probabilities, that—
(a) the defendant genuinely believed the victim to be committing, or to have just
committed, home invasion; and
-- 5 of 14 --
[2023] SASCA 133 The Court
4
(b) the defendant was not (at or before the time of the alleged offence) engaged
in any criminal misconduct that might have given rise to the threat or
perceived threat; and
(c) the defendant's mental faculties were not, at the time of the alleged offence,
substantially affected by the voluntary and non-therapeutic consumption of a
drug.
(3) In this section—
criminal misconduct means conduct constituting an offence for which a penalty of
imprisonment is prescribed;
drug means alcohol or any other substance that is capable (either alone or in
combination with other substances) of influencing mental functioning;
home invasion means a serious criminal trespass committed in a place of residence;
non-therapeutic—consumption of a drug is to be considered non-therapeutic
unless—
(a) the drug is prescribed by, and consumed in accordance with the directions of,
a medical practitioner; or
(b) the drug is of a kind available, without prescription, from registered
pharmacists, and is consumed for a purpose recommended by the
manufacturer and in accordance with the manufacturer’s instructions;
relevant defence means a defence under section 15(1) or section 15A(1).
15 This provision was inserted in 2003.2 As the Attorney-General explained in
the course of his second reading speech:3
…where an innocent occupier genuinely believes that he or she is defending himself or
herself from the commission of an offence of aggravated serious criminal trespass in a
residential building occupied by them, then, as a general rule, he or she may use such force
in defence of his or her person or property as she genuinely believe [sic] to be proportionate
to the threat that they genuinely believe that they face…
There are to be some exceptions to [s 15C]. For example, the occupier is not entitled to the
extended right if he or she is so intoxicated by self-induced intoxicants that his or her
judgment is substantially impaired. The Government has consistently maintained its
opposition to any form of the drunk’s defence and will be pursuing that matter further in
the future. In addition, the occupier is not entitled to the extended right if he or she was
engaged in criminal misconduct that might have given rise to the threat or perceived threat.
If, for example, the occupier was a thief in possession of a large quantity of stolen money
and the home invader was after the stolen money, it would be incongruous to treat the thief
in the same way as an innocent home owner protecting himself or herself.

16 At common law this Court may consider this kind of extrinsic material when
identifying the mischief to which the provision is directed.4 Under s 16 of the
Legislation Interpretation Act 2021 (SA) this material may also be considered in
order to assist with ascertaining the meaning of the provision.5
17 This statutory defence has been considered by the Court of Criminal Appeal
on a number of occasions.6 In R v Martin the Court described the common law
and initial iteration of the statutory defence,7 before accepting the following
submission regarding the operation of s 15C:8
Counsel for the Crown submitted that, on their proper construction, ss (1) and (2) of s 15C
provide that where the evidence does not negative beyond reasonable doubt that the
defendant genuinely believed that his conduct was necessary and reasonable for a defensive
purpose and prove beyond reasonable doubt that the victim was a police officer acting in
the course of his or her duties, then a defendant is entitled to the benefit of the defence even
though his conduct was not, objectively, reasonably proportionate to the perceived threat.
The defendant must establish, on the balance of probabilities, that the defendant genuinely
believed the victim to be committing, or to have just committed, home invasion. The
defendant must also establish that the defendant was not, at or before the time of the alleged
offence, engaged in any criminal misconduct that might have given rise to the threat or
perceived threat. Finally, the defendant must establish that the defendant’s mental faculties
were not, at the time of the alleged offence, substantially affected by the voluntary and non-
therapeutic consumption of a drug.
18 In that case there was an issue about whether a police raid on a suspected
drug laboratory was conducted lawfully. The applicant was inside the house with
his partner and her child. He and his partner denied that police had announced that
they were police before using a battering ram on the front door. The applicant said
he fired two shots at his front door, fearing a home invasion. The applicant was
acquitted of two counts of attempted murder but convicted on the two alternative
counts of endangering life. The appeal was not concerned with construing the
statutory defence but with the directions given about it, and the refusal by the trial
judge to conduct a voir dire into whether police had acted in accord with the law.
These criticisms were rejected and the refusal to conduct a voir dire was held to
be within the trial judge’s discretion. The appeals against conviction and sentence
were dismissed.

19 In R v Roberts the applicant appealed against his conviction on a charge of
causing serious harm with intent to cause serious harm.9 The applicant attacked
another man with a Samurai sword in circumstances where, on the defence case,
the other man was engaged in a home invasion. These circumstances were
contested. At the trial the applicant’s counsel disclaimed reliance on the s 15C
statutory home invasion defence. The trial judge did not leave that defence to the
jury to consider. The appeal was allowed, in part on the basis that the trial judge
had a duty to direct the jury on the law and the facts relevant to any defence raised
on the evidence, notwithstanding the conduct of counsel. The Court again
described the history of the statutory defence and addressed potential difficulties
facing trial judges directing juries about the operation of the statutory scheme.10
Justice Sulan (with whom Peek J agreed) rejected the proposition that the s 15C
defence only operated where an accused gave direct evidence of a genuine belief
that there was a threat of home invasion. His Honour held that, even if an accused
did not give evidence, or having given evidence was silent on the issue, there may
nonetheless be evidence from which the relevant belief may be inferred.11
20 Justice White (with whom Peek J agreed) explained that whilst in one sense
the requirement for a “genuine belief” involved a tautology, the adjective
“genuine” was used as a word of emphasis:12
In the context of s 15C, notions of scepticism may be inappropriate. However, the
requirement that the defendant prove that his or her belief that the victim was committing
a home invasion was genuine does seem to indicate that the evidence relied upon should
be examined closely.
21 Justice White also explained that the requirement that the accused prove a
genuine belief did not imply any element of reasonableness as to the accused’s
subjective belief.13 His Honour described the interrelationship between s 15 and
s 15C in the following way:14
The interrelationship between s 15, on the one hand, and s 15C appears therefore to be as
follows. It is for the prosecution to exclude as a reasonable possibility that the defendant
had a genuine belief that the conduct to which the charge relates was necessary and
reasonable for a defensive purpose. If the prosecution does not exclude that possibility then,

14 R v Roberts (2011) 111 SASR 100, [104] (White J, with whom Peek J agreed). See also his Honour’s
suggested questions for the jury between [105] and [113], concluding with “In my opinion, the proper
application of s 15C does not require a defendant to establish, in addition to a genuine belief that the
victim was committing, or had just committed, a home invasion, that his or her purpose was to defend
himself or herself (or another) against that invasion”. See also Peek J at [131]-[136], which includes
the following, “I simply wish to emphasise that the formulated questions delineate only the beginning
of the task of the trial judge. That task includes directing the jury as to the s 15C defence in the context
of the facts of the particular case, the needs of the particular jury and, quite often, in the context of other
defences to be considered quite apart from that arising under s 15C”.
-- 8 of 14 --
[2023] SASCA 133 The Court
7
in a case in which the victim is not a police officer acting in the course of his or her duties,
it is for the defendant to establish the circumstances giving rise to the home invasion
defence under s 15C(2). If the defendant establishes those matters, then he or she will have
a complete defence, that is, the prosecution will not have shown that the conduct was
unlawful. However, if the defendant does not satisfy the trier of fact on the balance of
probabilities of the home invasion defence, it will then be for the prosecution to exclude as
a reasonable possibility that the defendant’s conduct was, in the circumstances as the
defendant genuinely believed them to be, reasonably proportionate to the threat which the
defendant genuinely believed to exist.
22 In this case the applicant’s proposed appeal grounds relied upon the second
and third of the three essential limbs of s 15C(2) of the CLCA. These require that
a defendant establish on the balance of probabilities that the defendant was not,
whether at or before the time of the alleged offence, engaged in any criminal
misconduct that might have given rise to the threat or perceived threat
(s 15C(2)(b)), and the defendant’s mental faculties were not, at the time of the
alleged offence, substantially affected by the voluntary and non-therapeutic
consumption of a drug (s 15C(2)(c)).
The directions given on ss 15C(2)(b) and (c) of the CLCA
23 The trial judge gave the jury extensive directions, together with an aide
memoire, concerning self-defence. The directions on the s 15C(2) home invasion
defence were said to be so deficient as to result in a miscarriage of justice within
s 158(1)(c) of the Criminal Procedure Act 1921 (SA) (the CPA).15
24 After setting out the elements of the offence, followed by the elements of
self-defence, the trial judge addressed s 15C of the CLCA. Her Honour explained
that if the prosecution proved that the applicant’s conduct was disproportionate
then it was necessary for the jury to decide whether the s 15C home invasion
defence was proved by the accused on the balance of probabilities. This required
the proof of three matters:
1. That the accused genuinely believed that Mr Greene was committing or had
just committed a home invasion.
2. That the accused was not engaged in any criminal conduct at or before the
time of the alleged offence that might have given rise to the threat or
perceived threat faced.
3. That the accused’s mental faculties were not substantially affected by
voluntary and non-therapeutic consumption of drugs.
25 The trial judge recited some of the evidence earlier set out, together with the
evidence from Mr Greene that he was angry when he went to the home of the
applicant. When the trial judge came to apply the evidence to the elements of the
s 15C defence, her Honour said that it was for the accused to prove on the balance
of probabilities that he genuinely believed that the victim, Mr Greene, was
15 See, for example, Huxley v The Queen [2023] HCA 40, [40]-[43] (Gordon, Steward and Gleeson JJ).
-- 9 of 14 --
[2023] SASCA 133 The Court
8
committing or had just committed a home invasion. That is to say, that he had
entered the applicant’s home without permission and while intending to commit
an offence, being an assault.
26 The trial judge then directed the jury that the applicant must also demonstrate
that he was not engaged in any “criminal misconduct” that might have given rise
to a threat or perceived threat. Her Honour explained that “criminal misconduct”
is defined as conduct constituting an offence for which a penalty of imprisonment
is prescribed. As to this second element, the trial judge explained to the jury:16
In this case, you heard evidence that the accused had received a small quantity of a drug,
being methylamphetamine, from Mr Greene about two-and-a-half months prior to this
altercation. Possession of drugs, being methylamphetamine is a criminal offence for which
a penalty of imprisonment is prescribed by the Act that creates that offence. It is a matter
for you to assess whether it has been proved by the defence, on the balance of probabilities,
that the accused was not engaged in criminal misconduct that might have given rise to the
threat or perceived threat that he felt.
27 As for the third element, the trial judge said the following:17
Thirdly, the defence must establish that the accused’s mental faculties were not
substantially affected by a voluntary and non-therapeutic consumption of a drug. The
accused must prove this on the balance of probabilities. In this regard, you know that the
accused said that he had consumed a cone of cannabis that afternoon. That is the only
substance that you have heard any evidence in relation to occurring at the time of the
alleged offending. As I say, it is for the accused to prove this on the balance of probabilities
in relation to all three requirements.
The third requirement, that is, the one relating to the drugs, you will notice it says that the
accused must prove that he was not substantially affected by the consumption of any drug.
In this regard, you can have regard to any evidence that shows the accused and his
behaviour immediately subsequent to the offence, and any of the medical evidence that you
consider to be relevant. But it must be that the accused proves, on the balance of
probabilities, that he was not substantially affected by the consumption of a drug.
28 Later in the trial, after hearing from the then counsel for the applicant, the
trial judge added the following by way of a further direction to the jury:18
It is for the accused to prove that his mental faculties were not substantially affected. In
determining whether he has proved, on balance, that he was not substantially affected you
can take into account all of the evidence that has been given in this case, including the 000
call, his response to questions that he was asked on the 000 call; you can take into account
the interview with the police, the discussion with ambulance officers and the discussion
with medical practitioners, as they are recorded in P12; you can take into account all of

those matters in determining whether you are satisfied that he has proven that it is more
probable than not that he was not substantially affected by the consumption of a drug.
29 There is no dispute that neither counsel at the trial addressed the jury on
s 15C(2)(b) of the CLCA. This represented a considered forensic judgment by
each counsel.
30 Finally, there is no dispute that the applicant’s possession of
methylamphetamine, sourced from Mr Greene, potentially comprised “criminal
misconduct” as defined by s 15C(3), for it was “conduct constituting an offence
for which a penalty of imprisonment is prescribed”.19
The applicant’s contentions and their determination by this Court
31 The respondent suggested that there was room to question whether her
Honour was, in the absence of evidence from the applicant, obliged to leave the
s 15C defence to the jury. Similarly, it might also have been questioned whether
the applicant could have had any genuine belief concerning a home invasion in
circumstances where he had taunted Mr Greene about coming to see him and, when
Mr Greene did so, the applicant appears to have opened the screen door and
immediately engaged in a violent altercation whilst armed with a knife.
32 Despite these questions, the caution displayed by the trial judge was both
understandable and entirely appropriate. Pemble v The Queen requires that a trial
judge put to the jury any available defence which is raised on the evidence,
regardless whether the accused’s counsel has raised it, and even should reliance on
a defence be expressly disclaimed by counsel.20 The trial judge addressed all
elements of the s 15C home invasion defence as an adjunct to her obligation to
determine the “real issues” in the trial and so as to ensure that the applicant
received a fair trial according to law.21
33 The first criticism made by the applicant was whether what was said to be
the trial judge’s “unbalanced” direction adequately addressed the competing

direction regarding the second element (set out earlier) was so flawed that it
produced a miscarriage of justice.
34 This contention depended on the premise that the applicant was not engaged
in “criminal misconduct” at the time of the altercation. It was effectively
contended that the applicant’s anterior drug possession did not give rise to the
threat perceived by the applicant. The altercation occurred, it was said, as the result
of Mr Greene’s anger over hostile messaging because the applicant had refused to
repay his debt. Neither the messaging nor the failure to repay could be described
as “criminal misconduct”.
35 In these circumstances, it was asserted that the trial judge’s failure to put this
view of the case meant that her direction was “unbalanced”, effectively removing
the s 15C defence from the jury’s consideration.
36 There are two answers to the applicant’s criticism. First, it is not reasonably
arguable that the direction given by the trial judge was unbalanced. The direction
set out what was uncontentious – the applicant had been in possession of
methylamphetamine, and that is criminal misconduct – and then outlined a
question of fact for the jury’s determination. In so doing, her Honour did not take
any position on that question, whether for the prosecution or for the defence. The
question was articulated in neutral terms. It was not necessary for her Honour to
argue the applicant’s case, but rather to identify the issue and the question of fact
that the jury had to decide.
37 The direction made it clear that the issue of causation was for the jury to
determine on the balance of probabilities. There was no failure to provide a fair
and balanced direction.
38 Secondly, and in so far as it is now suggested that the jury should have been
asked to consider that there was only a debt and hostile messaging, disengaged
from the earlier drug possession, that must be rejected. Even if one were to
disregard the fact that the applicant cross-examined Mr Greene on the basis that
the altercation “developed over a scoop”,22 a trial judge is not obliged to direct the
jury on a view of the facts which is untenable.
39 It was not tenable on the facts of this case to suggest, as the then counsel for
the applicant put to the trial judge after she had given her summing up to the jury
on s 15C, that the jury should be directed that it was as if Mr Greene had loaned
the applicant $50 and he had failed to repay that debt.23 Counsel went on to suggest
that there was no “link between the scoop and the attendance of Greene … the link

is the refusal to pay the debt”. As her Honour responded, the debt was a drug debt.
It was not open to view the debt in any other way.
40 The applicant’s approach ignored the breadth of the s 15C(2)(b) exclusion.
In order to succeed with the statutory home invasion defence, the accused must
exclude all three of the essential limbs to s 15C(2), including the second,
s 15C(2)(b). This case raised two issues associated with this exclusion to the
defence. They were concerned with causation and timing. The first was whether
the criminal misconduct “might have given rise to the threat or perceived threat”
confronting the accused. The second issue was whether the accused’s criminal
misconduct occurred “at or before” the time of the alleged offending.
41 It was not sufficient for the accused to exclude criminal misconduct which in
fact gave rise to the threat, for the accused must exclude criminal misconduct
which “might” have given rise to the threat. In addition, the use of the phrase
“given rise to” suggests a very broad, open textured association between the
criminal misconduct and the threat. The use of that phrase demonstrates that it
will not necessarily assist an accused to point to other factual features which played
some part in giving rise to the threat, particularly if those features were themselves
connected with criminal misconduct.
42 In this case, the altercation necessarily arose as the result of the applicant’s
possession of methylamphetamine, even though that had occurred some weeks
before. Although there were additional features associated with the applicant’s
drug possession – in increasingly aggressive terms he had refused to pay for the
drugs he had received – those additional features did not deprive the applicant’s
drug possession of its causative effect on any threat potentially perceived by the
applicant. One could not divorce the applicant’s drug possession from the debt
owed in respect of that possession. They remained inextricably linked. That is to
say, the applicant’s drug possession may have given rise to the threat or perceived
threat as s 15C(2)(b) requires.24
43 Moreover, it was not necessary for the applicant’s drug possession to be
coincident in time with the offending.
44 When confronted with these propositions during the hearing before this
Court, the applicant responded that if the s 15C home invasion defence was not
open, then it should not have been left to the jury. Whether or not that proposition
should be accepted, there are many reasons why a trial judge might decide to leave
a defence to the jury even if, on final analysis, the defence is not open. As has
already been observed, the caution displayed by the trial judge in this case was
both understandable and entirely appropriate.
24 Although it was not argued in this way, and it is unnecessary to reach any conclusion, it might also have
been contended that the combination of taking possession of the drugs and then refusing to pay for them
could have been characterised as a form of theft, see s 134(1) of the CLCA, and thereby “criminal
misconduct”.

45 As for the second criticism concerning the third element of the home invasion
defence, this was addressed only fleetingly in writing and abandoned at the
hearing. In writing the applicant referred to material which suggested that he had
consumed only “one cone” of cannabis, which he asserted was a “relatively small
amount” which, together with his behaviour recorded in the police interview,
rendered it open to the jury to find that his mental faculties were not substantially
affected as s 15C(2)(c) requires.
46 This contention failed to engage with the requirements for demonstrating
error or a miscarriage of justice within s 158 of the CPA. Contrary to the proposed
ground of appeal, no complaint was made or is available concerning any of the
directions given by the trial judge concerning the third element of the home
invasion defence, set out earlier.
47 The applicant was right to abandon this proposed ground of appeal.
Conclusion
48 It is not reasonably arguable that there was any miscarriage of justice.25
49 Permission to appeal should be refused.
