Introduction
1 By indictment dated 5 May 2026, Mr Garlett has been charged
with eight offences contrary to the following provisions of the Criminal
Code (WA) (Code):
1. One count of aggravated assault with intent to steal whilst
armed contrary to s 393 (count 1).
2. Three counts of criminal damage contrary to s 444 (counts 2,
4 and 7).
3. One count of being armed with an offensive instrument in
circumstances likely to cause fear contrary to s 68 (count 3).
4. Two counts of unlawful assault occasioning bodily harm
contrary to s 317 (counts 5 and 6).
5. One count of unlawfully doing grievous bodily harm to another
contrary to s 297 (count 8).
2 On 23 April 2026 her Honour Chief Judge Wager ordered that
Mr Garlett be tried by judge alone pursuant to s 118 of the Criminal
Procedure Act 2004 (WA) (CPA).
3 Mr Garlett's trial was conducted before me on 2 June 2026.
4 At the commencement of the trial, pursuant to s 126(1)(d) of the
CPA Mr Garlett entered pleas of not guilty on the ground of mental
impairment under s 27 of the Code. Formal admissions were made
pursuant to s 32 of the Evidence Act 1906 (WA) (EA)
(s 32 admissions)1 in relation to each of the elements underpinning
counts 1 - 8 on the indictment and the facts as contained within the
State's amended statement of material facts dated 16 February 2025.2
Those admitted facts are relied upon by the State in support of its case
against Mr Garlett.
5 Resolution of this trial, as it relates to each count,
requires determination of the following two questions:
1 Exhibit 1.
2 Exhibit 3.
-- 4 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 5
1. Was Mr Garlett mentally impaired with the meaning of s 27(1)
of the Code at the time that he did the act, or acts that constitute
the elements of the offence with which he has been charged?
2. If Mr Garlett was mentally impaired at the time of doing the
relevant act, or acts, did his impairment deprive him of one or
more of the capacities specified in s 27(1)?
6 Both the State and Mr Garlett adduced expert psychiatric evidence
as to Mr Garlett's state of mind at the relevant times. Both positively
submitted that I could be satisfied on the balance of probabilities that
Mr Garlett was deprived of the capacity to know that he ought not do
the act or make the omission giving rise to criminal responsibility.
7 For the reasons that follow, I find Mr Garlett not guilty on account
of mental impairment in respect to each of the eight counts with which
he has been charged.
Legal principles
8 Pursuant to s 119(1) of the CPA, a judge sitting alone must apply,
so far as practicable, the same principles of law and procedure as would
be applied in a trial before a jury. Section 120 requires the trial judge
to outline in the judgment the principles of law that they have applied
and the findings of fact upon which they have relied.
General principles
9 An accused person is presumed to be innocent of the charge,
or charges, presented against them. That presumption remains until
such time as their guilt is proven to the criminal standard. If guilt is not
proven the presumption of innocence remains.
10 The burden of proving an accused person's guilt is on the State.
An accused person does not have to prove their innocence;
indeed, they do not have to prove anything.
11 The standard of proof required is proof beyond reasonable doubt.
It is sufficient for me to say that this is the highest standard known to
the law. It is a high standard, but it is not an impossible standard.
12 To discharge that burden, the State must prove beyond reasonable
doubt each of the elements of the offence alleged against Mr Garlett.

[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 6
13 One of the aspects of the onus of proof being on the State is that
the accused has at all times, a right to silence. The right to silence does
not commence in this court. A person who is arrested by the police has
that right from the beginning and it continues to the trial. An accused
person is not obliged to speak to the police or to give evidence at their
trial, but they may do so if they wish. In this case Mr Garlett chose to
exercise his right to silence. It would be wrong to draw any adverse
conclusion from the exercise of that right. The silence of the accused is
not evidence against him. Nor can it be used to support any inference
adverse to him. The fact that an accused person chooses to remain
silent is not an admission of anything. It cannot be used to fill in any
gap in the prosecution case nor does it strengthen it.
14 I must decide the case based on the evidence which has been
presented during the trial. I must assess the evidence dispassionately,
in a rational and impartial way. My decision cannot be based on
prejudice against, or sympathy towards, anyone. My task is to consider
what logical conclusions can be drawn from the evidence as a whole.
15 I must not guess or speculate about matters not in evidence or look
for theories that are not supported by the evidence. I am permitted to
draw inferences. Inferential reasoning is not speculation.
Inferential reasoning is the drawing of a logical deduction from the
proven facts.
16 If it is necessary to draw inferences as to essential facts from the
evidence, I am not permitted to draw an inference adverse to
the accused unless that inference is the only reasonable one open on the
evidence. In deciding what inferences are reasonably open from
the evidence it is important not to look at the evidence in a piecemeal
way but as a whole to see what inferences can be drawn. If there is an
innocent explanation that is open then an inference of guilt cannot be
drawn.
17 I am the judge of the law and of the facts. I must assess the
honesty, accuracy and reliability of each of the witnesses. A witness
may be honest, but unreliable. I should only act on evidence that I find
to be honest, accurate and reliable.
18 I can choose to accept and reject a witness's evidence, either in
part or in whole. In doing so, I am bound to consider all of the
evidence presented at trial. It is for me to decide what weight is to be
given to the evidence.

19 In the present case, the forensic psychiatrists called by the State
and the defence are largely in agreement in their opinions in this case.
While I am not bound to accept and act upon expert evidence, I am not
entitled to disregard it capriciously.3
20 I am required to consider and decide each charge separately,
on the evidence relevant to that charge. I must not reason automatically
from a finding on one charge to the same finding on the other.
My verdicts need not be the same on each charge. I must not draw any
inference against the accused as a result of the fact that there are eight
charges and I must not engage in propensity reasoning in arriving at my
conclusion.
Agreed facts and evidence
21 Section 93 of the CPA relevantly provides:
(1) If an accused pleads not guilty to a charge on account of mental
impairment and the judge is satisfied -
(a) that the only fact in issue between the accused and the
State is whether, under The Criminal Code section 27,
the accused is not criminally responsible for an act or
omission on account of mental impairment; and
(b) that the prosecutor consents, and the accused does not
object, to the judge doing so; and
(c) that it is in the interests of justice to do so,
the judge -
(d) may decide the issue referred to in paragraph (a) on any
evidence and in any manner the judge thinks just; and
(e) for that purpose, may ascertain any fact by the verdict
of a jury or otherwise; and
(f) may find the accused not guilty of the charge on
account of mental impairment; and
(g) if such a finding is made and a jury has been sworn to
give a verdict on the charge, must discharge the jury
from giving its verdict on the charge.

22 The parties have consented to an agreed statement of facts,
which has been admitted by Mr Garlett pursuant to s 32 of the EA,
together with an agreed timeline which is relied upon.4 I am satisfied
that it is in the interests of justice to receive the amended statement of
facts and the agreed timeline of events as establishing the factual
circumstances relevant to the determination of the issues in this case.
23 The amended statement of facts are in the following terms:5
Count 1 - AR 5770/23
1. At about 6.55 pm on Thursday 20 April 2023, the accused was
driving a silver Ford Focus registration [redacted] in
a south-easterly direction on Cameron Street Langford.
2. The accused stopped his vehicle in the vicinity of [an address in
Langford]. The accused stopped alongside the complainant.
The complainant was sitting in his red Holden Barina
registration [redacted] which was parked on the side of the road.
The complainant was parked as he had just dropped a friend off.
3. The complainant was unsure what was occurring, so he wound
his driver's side window down. The accused did the same to his
passenger's side window. The accused then said, 'Do you have
your wallet or your phone on you'. As the accused said it,
he held up a meat clever in his right hand. The complainant was
scared and said, 'No I don't'. The accused then leaned towards
the complainant and pointed the knife at him. The complainant
drove off towards the end of the street, although he drove over
a curb and his vehicle stopped working.
4. The accused drove after the complainant and stopped behind the
complainant. The accused came up to the complainant's driver's
side window. The accused hit the window with the knife
causing it to shatter. The accused shouted, 'Open your door
right now'. The complainant was scared and told the accused he
needed to open it from the outside. The complainant gave the
accused the key. At the time the complainant's locks were faulty
and had to be opened from the outside.
5. The accused opened the door and learnt into the car whilst
holding the knife. The accused shouted, 'I know you have your
wallet or phone' and 'don't play around, don't fuck with me'.
The complainant gave the accused his phone, and the accused
told him to unlock it. As the complainant unlocked his phone

[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 9
the accused put the knife against the complainant's skin and cut
down his face. This caused a laceration and bleeding to the
complainant's face. The complainant felt intense pain in his
face.
6. The accused then put the knife on the complainant's leg and
said, 'Do you want me to cut your fucking leg off'. The accused
then put the knife on the complainant's wrist and said, 'Do you
want me to cut your fucking arm off'. The accused then said,
'Go into your banking app right now'. The complainant
said, 'Okay, I'll do whatever you want' and opened his banking
app. The complainant's bag then dropped out of the car and the
accused said, 'what the fuck are you doing, I've been dying to kill
someone all night'.
7. The complainant then accessed his banking app, and the accused
told him to send him $2,000 through pay ID. The accused saw
the complainant had about $6,000 in his account. The accused
then demanded the complainant transfer him $5,000.
The complainant transferred $5,000 through pay ID to [mobile
number redacted]. The accused then walked back to his car and
drove off. The complainant immediately called police who
attended and took photographs of his facial injury and the
broken window of his car.
8. The accused's intention during the incident was to steal money
from the complainant. The accused used violence,
and threatened violence, in order to obtain the money (count 1).
9. The complainant was able to have the $5,000 transfer reversed.
Banking records reveal the money was transferred into an
account registered in the accused's name. The complainant
subsequently participated in a photoboard identification
procedure and identified the accused.
Count 2 - AR 5774/23
10. This incident occurred shortly after the commission of Count 1.
11. At about 7.10 pm on Thursday 20 April 2023 the second
complainant was delivering food for Door Dash in a rental
vehicle. The rental vehicle was a black Hyundai Getz bearing
registration [redacted].
12. The complainant was delivering an order to [an address in
Queens Park]. Whilst driving along Roe Highway Welshpool,
the complainant was in front of the accused who was still
driving the silver Ford Focus registration [redacted].
The complainant was driving at approximately 100 km's/h.
The accused started flashing the complainant with his high
beams for one to two minutes. The accused then started
honking his horn at the complainant.

ASTILL DCJ
[2026] WADC 45 [JM] Page 10
13. The accused overtook the complainant and started breaking in
front of the complainant which required the complainant to slow
down. The accused then stopped in the middle of the road
blocking the complainant's lane. The accused exited his vehicle
and approached the complainant's vehicle. The complainant was
scared and started to reverse. The accused managed to reach
the complainant's passenger side window where he smashed the
window (count 2).
14. The complainant then drove off and continued to [an address in
Queens Park]. When the complainant arrived, he was getting
out of his vehicle when the accused appeared and started
punching him. The complainant didn't realise the accused had
followed him and he asked, 'Why are you hitting me'.
The accused was swearing and referred to the complainant
having done something wrong whilst driving. The accused then
leant against the complainant's vehicle leaving a visible
handprint on his window. The accused then drove off.
15. The incident was witnessed by [named person] who lived at
[an address in Queens Park]. [Named person] recorded the
accused's registration plate and provided it to police. The visible
handprint on the complainant's window was examined and a
fingerprint matching the accused was identified.
The complainant also participated in a photoboard identification
procedure and identified the accused.
Counts 3, 4 & 5 - AR 5772/23, 5772/23 & AR 5771/23 respectively
16. This incident occurred shortly after the commission of Count 2.
17. At about 7.40 pm on Thursday 20 April 2023, the third
complainant was driving his white Hyundai Accent registration
[redacted] along Wharf Street Queens Park. The accused was
driving behind him. The accused was still driving the silver
Ford Focus registration [redacted].
18. The accused started beeping his horn at the third complainant.
The accused was driving very close to the third
complainant such that the third complainant couldn't see the
accused's registration plate. The accused continued beeping his
horn, so the third complainant pulled over to the left and waved
for the accused to overtake him. The accused stopped behind
the third complainant and continued to beep his horn, so the
third complainant continued driving.
19. The third complainant approached the intersection at Wharf
Street and Welshpool Road where he indicated to turn right.
The accused did the same. Having seen that, the third
complainant decided to turn left to get away from the accused.

ASTILL DCJ
[2026] WADC 45 [JM] Page 11
When the third complainant turned left the accused followed.
The third complainant was scared and believed the accused was
following him.
20. The third complainant pulled into a 7-Eleven carpark.
The accused parked next to him. The accused got out of the
vehicle and approached the third complainant's driver's side
window. The accused shouted, 'I'll punch you', 'come out',
and 'I'll kill you'. The third complainant said, 'It's okay, you go'.
The accused then raised his fists and adopted a fighting stance.
The third complainant was scared and refused to open his door
or window.
21. The accused then walked back to his car. The third complainant
started driving away. The third complainant looked in his
rearview mirror and saw the accused had moved his car so that
he was now blocking the third complainant. The accused started
walking back towards the third complainant's vehicle. The third
complainant saw the accused had a meat clever in his hand
which caused him and other persons present to be fearful
(count 3). The accused was yelling 'get out of the car, I'll kill
you'.
22. The accused started hitting the third complainant's window with
the knife whilst yelling. The third complainant moved over to
the passenger side as he thought the window was going to break
as the accused hit it forcefully several times. This caused
multiple scratches to the third complainant's driver's side
window and door (count 4).
23. Whilst this was occurring [the fourth complainant] was parked
at the 7-Eleven. The fourth complainant was watching the
accused strike the third complainant's car with the meat clever.
The fourth complainant could also hear the accused yelling.
The accused then walked back to his vehicle and put the knife
away. The accused then got into the driver's seat. The fourth
complainant thought the incident was over, so he got out of his
car and started walking towards the 7-Eleven entry.
24. The accused then said to the fourth complainant, 'What's up with
you, cunt'. The accused then quickly walked over to the fourth
complainant. The fourth complainant was fearful of the
accused. The accused then punched the fourth complainant five
times to the head with a closed fist. The fourth complainant
immediately felt pain and the taste of blood in his mouth.
The fourth complainant suffered bodily harm due to the assault
(count 5). The accused then walked back to his car and drove
off.
-- 11 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 12
25. Parts of the incident were caught on CCTV. It was also
witnessed by several people, some of whom recorded the
accused's registration plate. The fourth complainant
subsequently participated in a photoboard identification
procedure and identified the accused.
Arrest for count 1 - 5
26. At about 8.50 pm on Thursday 20 April 2023 police officers
were pursuing the accused in the silver Ford Focus registration
[redacted] due to reports arising from the previous incidents.
Following pursuit police were able to stop the accused and arrest
him.
27. During the arrest police identified the accused was wearing
clothing that matched what he was wearing during the incident
subject to counts 3, 4 and 5. Police then search his vehicle and
found a meat clever sitting between the driver's seat and centre
console. The accused was charged with several offences and his
bail was refused.
Count 6 - PE 29671/24
28. The accused was released to bail on 19 December 2023 after
having served 244 days in custody.
29. At about 5:30pm on Saturday 25 May 2024, the accused was
walking in the vicinity of [an address in Langford]. This is the
address of the fifth complainant. The accused lived nearby at
[an address in Langford]. The fifth complainant started
reversing his vehicle out of his driveway and onto the road.
The fifth complainant's wife was also in the vehicle.
30. As the fifth complainant was reversing, he saw the accused
walking towards him. The fifth complainant stopped and wound
his driver's side window down. The accused immediately
punched the fifth complainant once to his right cheekbone (start
of continuing assault subject to count 6). The fifth
complainant felt immediate pain and was confused as to what
was happening.
31. The fifth complainant moved across towards the centre console
to try and get away from the accused. The fifth complainant
then closed the window. The accused kicked the side of the fifth
complainant's vehicle. The accused said, 'Are you Travis'.
The fifth complainant opened his door and said, 'My name is not
Travis. Mine is [name redacted] and I'm from the UK.
What's your problem'.
-- 12 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 13
32. The accused then punched the fifth complainant again to the
same cheekbone (end of continuing assault subject to
count 6). The fifth complainant again felt immediate pain in his
cheek bone [sic]. The fifth complainant's wife told the fifth
complainant to drive away. The fifth complainant drove away
from the area and his wife called police. As a result of the
assault the fifth complainant suffered bodily harm.
33. The fifth complainant subsequently participated in a photo board
identification procedure and identified the accused.
Count 7 - PE 29672/24
34. This incident occurred shortly after the commission of Count 6.
35. At about 6.45 pm on Saturday 25 May 2024, the accused was at
the BP service station on Nicholson Road Langford. The sixth
complainant arrived at the service station in his Toyota
Landcruiser registration [redacted]. The sixth complainant
parked in front of the night counter and exited his vehicle.
36. As the sixth complainant got out of his vehicle, he heard the
accused call him a 'faggot' in an aggressive voice. The accused
said, 'You think you're better than me because you're dressed
better than me. You think you're top shit'. The sixth
complainant was dressed up as he was on his way to a 21st
birthday party. The sixth complainant then shook his head and
the accused said, 'Don't shake your head at me cunt. I'll bash
you'.
37. The sixth complainant went inside and purchased some chewing
gum. The accused followed him inside. As the
sixth complainant was leaving the accused said, 'Wait outside
for me cunt. I'll drag your head along the floor'. The sixth
complainant walked outside and got in his vehicle.
The sixth complainant locked the doors, as he was fearful the
accused might do something.
38. The accused came out and approached the sixth complainant's
driver's door. The accused yelled, 'Get out of the car. I'll bash
you'. The accused tried to open the door but was unable too
[sic] as it was locked. The accused then completely ripped the
driver's side door handle off and threw it at the vehicle
(count 7). The accused then walked off. The cost to repair the
door handle was $285.
39. The incident was caught on CCTV.
Count 8 - PE 29670/24
40. This incident occurred shortly after the commission of Count 7.

[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 14
41. At about 10 pm on Saturday 25 May 2024, the accused
re-attended the BP station on Nicholson Road Langford.
The accused was wearing the same clothing as he was wearing
in the CCTV that captured Count 7.
42. The seventh complainant arrived at the service station with his
wife. The seventh complainant was driving his Toyota Camry
registration [redacted]. The seventh complainant exited his car
and attended the night window to buy some tobacco.
The accused approached the same night window.
43. The accused said to the seventh complainant, 'What did you say
mate'. The seventh complainant replied, 'I said nothing'.
The accused grabbed the seventh complainant by the neck and
pushed him backwards. The seventh complainant did not want
to fight and immediately began retreating into the forecourt to
get away from the accused. The accused pursued the seventh
complainant and pushed him to the chest area.
44. The accused then unlawfully punched the seventh complainant
to the jaw (count 8). The punch was forceful and the seventh
complainant immediately lost consciousness and fell backwards
onto the concrete floor. The accused walked away but then
walked back to the seventh complainant and lifted his arm.
The seventh complainant's arm was limp as he was still
unconscious.
45. The seventh complainant's wife then ran over, and the accused
walked back towards the night window. The accused purchased
some orange juice and walked away from the area. The entire
incident was caught on CCTV. A witness also captured a short
video of the accused standing over the seventh complainant.
46. [A named person] witnessed the incident, and he followed the
accused when he left the service station after the assault.
[The named person] followed the accused to the vicinity of
[an address in Langford]. At around 10.10 pm police were
patrolling the area looking for the accused. [The named person]
directed them to that area. Police arrested the accused at his
home address in Langford.
47. The seventh complainant was taken to hospital in an ambulance.
Investigations revealed the seventh complainant had:
47.1. A left subdural hematoma;
47.2. Left subarachnoid haemorrhage;
47.3. Contracoup bifrontal subdural hematoma with an
associated subarachnoid haemorrhage;
-- 14 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 15
47.4. Fracture through the left temporal bone with extension
posteriorly involving the parieto-occipital suture; and
47.5. Pneumocephalus.
48. The seventh complainant was intubated and required intracranial
monitoring. Intubation was necessary as the seventh
complainant's breathing was compromised by his head injury.
The seventh complainant developed excessive brain swelling
and had to have surgery to remove bone from his skill [sic] to
reduce the swelling.
49. If the seventh complainant did not have surgery, the pressure
inside his brain would've likely risen to such a degree that his
brain would've forced its way down the foramen magnum.
This would have compromised the ability of the breathing centre
of the brain to work. This would have resulted in death.

Elements of each offence
24 I cannot find Mr Garlett guilty of a count that is alleged against
him unless the State has proved each element of that offence beyond
reasonable doubt.
25 Where the State alleges a circumstance of aggravation, that matter
does not constitute an element of the offence, but must nevertheless be
proved beyond reasonable doubt if it is to be established.
Consideration of whether such a circumstance has been proved to that
standard arises only if I am first satisfied beyond reasonable doubt of
Mr Garlett's guilt in respect of the charged offence.
26 Before I could find Mr Garlett guilty of any of the counts alleged
against him, I must first be satisfied that he is the person who
committed the act or omission constituting the offence. This is the
element of identity, which is common to all counts. Pursuant to
the s 32 admissions, Mr Garlett has admitted his involvement in each of
the offences the subject of the counts. Accordingly, identity is not in
issue and, on the basis of that admission, I am satisfied beyond
reasonable doubt that this element is established in respect of each
count.

Aggravated assault with intent to steal whilst armed
27 To establish the offence of contravening s 393 of the Code,
the prosecution must prove each of the following elements beyond
reasonable doubt:
1. That the accused had the intention to steal. Under s 371 of the
Code, a person steals if they take something capable of being
stolen, or convert property, with the intention of permanently
depriving the owner of it. For the purposes of this provision,
'intention' means to bring about a specific result.6 A person will
therefore have the intention to steal if their purpose was to take
such an item, or to convert property, in order to permanently
deprive the owner of it.
2. That the accused either used violence or threatened to use
violence. 'Violence' refers to the application of physical force
intended to cause injury to another person. To 'threaten
violence' means expressing an intention to cause such injury,
though it is not necessary to prove that the person genuinely
intended to carry out the threat.
3. That the violence was used, or threatened, for the purpose of
obtaining the property in question, or for preventing or
overcoming any resistance to its taking. The relevant intention
must have been held for the purposes of achieving that specific
result.
28 The prosecution alleges that Mr Garlett intended to steal 'money'
from the named complainant by compelling him to make an electronic
transfer of $5,000 into an account from which Mr Garlett could
withdraw the funds. Mr Garlett accepts that he, at a minimum,
held that intention. In light of that admission, it is not necessary for me
to determine whether an electronic transfer constitutes 'money' or
property capable of being stolen for the purposes of s 370 or s 371(7) of
the Code.7

[2026] WADC 45 [JM] Page 17
29 Further, as Mr Garlett accepts that he held that intention, any issue
as to his capacity to form that intention by reason of any mental
impairment operating at the relevant time, does not arise. However,
I note that the issue of insanity would ordinarily fall to be determined
before the question of intent.8
30 Mr Garlett admits he used violence to the named complainant to
obtain the money he intended to steal from him. On the basis of that
admission, I am satisfied beyond reasonable doubt of the elements
that constitute count 1.
Circumstances of aggravation
31 Count 1 also alleges two circumstances of aggravation:
1. That Mr Garlett was armed with an offensive instrument,
namely a knife; and
2. That Mr Garlett did bodily harm to the named complainant.
32 Pursuant to the s 32 admissions made by Mr Garlett, he admits
both circumstances of aggravation. Ordinarily, this would provide a
sufficient evidentiary basis for me to be satisfied beyond reasonable
doubt that both circumstances have been established.
33 By definition, a circumstance of aggravation that properly falls
within the meaning of s 7(3) of the Sentencing Act 1995 (WA) is not an
element of an offence.9 A circumstance of aggravation is only ever
relevant to determining the applicable maximum penalty, rather than to
establishing an accused's criminal responsibility for the act or omission.
34 Where an accused's criminal responsibility depends upon proof of
a purported circumstance of aggravation, that circumstance is, in truth,
an element of the offence. In the present case, the alleged
circumstances of aggravation are properly characterised as true
circumstances of aggravation, rather than elements.

[2026] WADC 45 [JM] Page 18
35 As noted above at [29], once I am satisfied that Mr Garlett
committed the act or omission that would ordinarily attract criminal
responsibility, I must first determine whether he is relieved of that
responsibility before proceeding to consider the final element of
intention. Ordinarily, that question of guilt is resolved prior to
addressing the maximum penalty that may apply if he is found
criminally responsible.
36 Further, an accused who is relieved of criminal responsibility for
the relevant act or omission is no longer liable to punishment. In such
circumstances, the question of the applicable maximum statutory
penalty becomes immaterial.
37 Although the question of whether a circumstance of aggravation
has been established may bear upon the fixing of any limiting term
under s 50 of the Criminal Law (Mental Impairment) Act 2023 (WA)
(CLMIA), that issue appears to have been substantively addressed in
The State of Western Australia v Chokolich10 and then developed
further in McCullock.11 Adopting the Chief Justice's reasoning and
applying it to the present case, it suggests the question of whether the
circumstances of aggravation are proven will have no material effect at
all.
38 In any event, it is clear that the issue of whether Mr Garlett is
relieved of criminal responsibility pursuant to s 27 of the Code must be
determined first before considering whether the alleged circumstances
of aggravation have been established. If it is found that s 27 applies,
the question of whether those circumstances of aggravation have been
proven need not be considered further.
39 As noted at [7] above, and for the reasons elaborated below, I am
satisfied that Mr Garlett ought to be acquitted of all counts, including
count 1, because of mental impairment. It follows that in light of that
finding, notwithstanding the admissions he has made, resolution of the
question of whether the alleged circumstances of aggravation have been
proven does not fall to be determined.

Criminal damage
40 Counts 2, 4, and 7 each allege that Mr Garlett committed the
offence of criminal damage to a vehicle, contrary to s 444 of the Code.
The difference in each count is each count simply relates to damage
caused to a separate vehicle.
41 To establish the offence of contravening s 444 of the Code,
the prosecution must prove each of the following elements beyond
reasonable doubt:
1. That the accused destroyed or damaged property. 'Property' is
defined by s 1(1) of the Code. There is no dispute that a motor
vehicle is capable of amounting to 'property' as defined.
2. The accused did so wilfully. Section 443 of the Code provides
that a person will 'wilfully destroy or damage property' if they
do an act, or omit to do an act, with the intention of destroying
or damaging property, or knowing or believing that the act or
omission is likely to result in the destruction or damage to the
property.
3. That the accused acted unlawfully. Section 441 of the Code
provides that damage to another person's property, done without
that person's consent, is unlawful unless it is authorised,
justified, or otherwise excused by law.
42 Mr Garlett admits in relation to counts 2, 4 and 7 that he wilfully
and unlawfully caused damage to each of the motor vehicles the subject
of those counts. On the basis of those admissions, I am satisfied
beyond reasonable doubt of the elements that constitute each of those
counts.
Being armed in a manner likely to cause fear
43 To establish an offence against s 68 of the Code the prosecution
must prove each of the following elements beyond reasonable doubt:
1. The accused was armed. 'Armed' means to bear arms. To bear
something is to carry or equip. To be armed a person merely
needs to have a weapon sufficiently close enough to be made
available should the person choose to use it.
-- 19 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 20
2. That the object with which the accused was armed was an
offensive instrument. An object that ordinarily has a lawful or
innocent purpose may nonetheless constitute an 'offensive
instrument' if it is carried or used with the intention that it be
readily available for use to attack and inflict injury should the
occasion arise.12
3. The accused did so in circumstances likely to cause fear to any
person. 'Likely' means probable and mere possibility or chance
is insufficient.
44 Mr Garlett admits he was armed with a knife and in circumstances
where it would be capable of constituting an offensive instrument.
45 Although the indictment specifies the offensive instrument as a
'knife', the facts admitted by Mr Garlett show that the item he was
armed with was a meat cleaver. I am satisfied that a meat cleaver,
particularly in the circumstances in which Mr Garlett admits he was
holding it, is capable of constituting an 'offensive instrument'.
46 Further, Mr Garlett admits that he was armed with the meat
cleaver in circumstances likely to cause fear. Those circumstances are
outlined above at [23(21)] - [23(25)]. I am satisfied that the way he
was armed with the meat cleaver was such that, viewed objectively,
it was likely to cause fear to another or others.
47 I am satisfied beyond reasonable doubt of each of the elements
constituting this count have been established.
Assault occasioning bodily harm
48 Counts 5 and 6 allege Mr Garlett unlawfully assaulted another and
thereby caused bodily harm contrary to s 317 of the Code. The only
difference in relation to each count is that each count relates to bodily
harm caused to a separate person.
49 To establish the offence of contravening s 317 of the Code,
the prosecution must prove each of the following elements beyond
reasonable doubt:
12 Van Den Berg v The Queen [1984] WAR 162, 165 (Burt CJ), 69 (Smith J), 172 - 173 (Pidgeon J); The
State of Western Australia v Majok [2005] WASC 13 [39], [43] - [44].

[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 21
1. The accused assaulted the named person. The term 'assault' is
defined by s 222 of the Code and includes, amongst other
things, the striking, touching, moving or application of force of
any kind to the person of another, either directly or indirectly,
without that person's consent.
2. The named person suffered bodily harm. 'Bodily harm' is
defined in s 1(1) of the Code as any bodily injury that interferes
with health or comfort. To satisfy this element, the prosecution
must prove both injury and pain and/or discomfort.13
3. The bodily harm was caused by the accused's assault.
4. The assault was unlawful in that it was not authorised,
justified or excused by law. The accused bears no onus to prove
there was a lawful justification.
50 In relation to count 5, the prosecution alleges that the bodily harm
was caused to the named person when Mr Garlett struck him multiple
times to the face. It is an admitted fact that, as a result, the named
person immediately experienced pain and could taste blood in his
mouth. I infer from this that an injury was caused to the named
person's mouth. I am satisfied that the combination of injury to his
mouth and the resulting pain is capable of constituting bodily harm.
51 Similarly, in relation to count 6, the prosecution alleges that the
bodily harm was caused to the named person when Mr Garlett struck
him twice to the cheek. It is accepted that these blows caused him
immediate pain. Although the precise nature of the injury has not been
identified, Mr Garlett admits that the named person sustained an injury
amounting to bodily harm. In light of that admission, and despite the
absence of a clearly identified injury, I am satisfied that named person
suffered a bodily injury capable of constituting bodily harm.
52 Mr Garlett admits that there was no lawful basis for him to assault
each of the individuals named in counts 5 and 6 in the circumstances in
which those incidents occurred. The relevant circumstances are set out
above at [23(23)] - [23(25)] and [23(30)] - [23(32)] respectively.
Having regard to those circumstances, I am satisfied that there was no
authorisation, justification, or excuse that would render either assault
lawful and, accordingly, each was unlawful.

53 I am satisfied beyond reasonable doubt of the elements that
constitute each of these two counts.
Grievous bodily harm
54 Count 8 alleges Mr Garlett unlawfully caused grievous bodily
harm to named person contrary to s 297 of the Code. To establish this
offence, the prosecution must prove each of the following elements
beyond reasonable doubt:
1. The named person suffered grievous bodily harm. An injury
will amount to a 'grievous bodily harm' if it is a bodily injury of
such a nature as to endanger or be likely to endanger life, or to
cause or be likely to cause permanent injury to health. In this
context, 'likely' means a substantial, that is, a real and not
remote, chance that, if left untreated, the injury would cause
permanent injury to health.14
2. That the accused caused the grievous bodily harm. The issue of
causation is to be determined by applying common sense to the
facts as found, bearing in mind that it involves attributing legal
responsibility in a criminal context.15
3. Thae accused caused the grievous bodily harm unlawfully.
For the purposes of s 297, the word 'unlawful' means prohibited
by law or contrary to law and not excused.16
55 Mr Garlett admits that he unlawfully inflicted an injury amounting
to grievous bodily harm on the named person. The circumstances in
which that injury was caused are set out above at [23(40)] - [23(44)]
and the injuries sustained by the named person, together with the
treatment required, are detailed at [23(47)] - [23(49)]. Independently of
those admissions, based on the circumstances in which the assault
occurred, I am satisfied that there was no lawful basis for the infliction
of that harm. I am also satisfied that, in the absence of medical
treatment, the injuries were of such a nature as to be likely to endanger
life and therefore constitute grievous bodily harm.
56 I am satisfied beyond reasonable doubt of each of the elements
constituting this count.

57 Having concluded that the elements have been established in
respect of each of the eight counts with which Mr Garlett is charged,
I must now determine whether he should be relieved of criminal
responsibility for any of those counts by operation of s 27 of the Code.
Mental impairment
58 Section 27 of the Code provides:
(1) A person is not criminally responsible for an act or omission on
account of mental impairment if at the time of doing the act or
making the omission he is in such a state of mental impairment
as to deprive him of capacity to understand what he is doing,
or of capacity to control his actions, or of capacity to know that
he ought not to do the act or make the omission.
(2) A person whose mind, at the time of his doing or omitting to do
an act, is affected by delusions on some specific matter or
matters, but who is not otherwise entitled to the benefit of
subsection (1), is criminally responsible for the act or omission
to the same extent as if the real state of things had been such as
he was induced by the delusions to believe to exist.
59 Section 26 of the Code provides that every person is presumed to
be of sound mind until the contrary is proved. Mr Garlett bears the
onus of proving, on the balance of probabilities, that he is not
criminally responsible pursuant to s 27.17
60 Section 1(1) of the Code defines 'mental impairment' as including
'mental illness'. 'Mental illness' is defined as meaning:
[a]n underlying pathological infirmity of the mind, whether of short or
long duration and whether permanent or temporary, but does not
include a condition that results from the reaction of a healthy mind to
extraordinary stimuli.
61 What constitutes an 'infirmity of the mind' and the meaning of
'mental illness' more broadly was considered in The State of Western
Australia v Herbert18 which, for the purposes of these reasons, I adopt:
47 An 'infirmity of the mind' is a weakness of the mind.
The Shorter Oxford Dictionary defines 'pathological' to mean
pertaining to or dealing with pathology. In turn, it defines
'pathology' to mean either the science or study of disease;
that department of medical science, or of physiology,

which treats of the causes and nature of diseases, or abnormal
bodily affections or conditions. Thus, an underlying
pathological infirmity of the mind is an underlying infirmity of
the mind which is related to disease or an abnormal bodily
condition.
48 The definition of 'mental illness' reflects some of the comments
made by King CJ in Radford (1985) 20 A Crim R 388, 396
about the meaning of the expression 'disease of the mind' which
is used in the common law of insanity. The then Chief Justice
of the Supreme Court of South Australia said:
(1) 'disease of the mind' is synonymous with 'mental
illness';
(2) a temporary disorder or disturbance of an otherwise
healthy mind caused by external factors is not properly
regarded as a disease of the mind;
(3) major mental illness or psychoses such as
schizophrenia are clearly diseases of the mind as are
physical diseases, such as psychomotor epilepsy and
arteriosclerosis, when they affect the soundness of the
mental faculties;
(4) disease of the mind is to be distinguished from 'mere
excitability of a normal man, passion, even stupidity,
obtuseness, lack of self-control and impulsiveness'; and
(5) in order to constitute insanity in the eyes of the law, the
malfunction of the mental faculties called 'defect of
reason' in the M'Naghten rules, must result from an
underlying pathological infirmity of the mind, be it of
long or short duration and be it permanent or
temporary, which can be properly termed mental
illness, as distinct from the reaction of a healthy mind
to extraordinary external stimuli'.
49 In R v Falconer [1990] HCA 49; (1990) 171 CLR 30, the High
Court generally approved of King CJ's comments even in the
context of the then Criminal Code provisions.
50 When Falconer was decided, the Code s 27 was differently
worded. Section 27 was amended and the definition of mental
impairment was inserted after Falconer was delivered.
The subsequent amendments to the Code are consistent with
King CJ's statement of principles in Radford, although the Code
definition of 'mental impairment' is broader than that of 'disease
of the mind' which was considered by King CJ. Nevertheless,
-- 24 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 25
acute intoxication with alcohol and/or drugs is not a 'mental
impairment'.
51 What is a mental illness is a question of law for the judge.
Whether or not the facts disclose a state of mental illness is a
question for the decider of fact.
Psychiatric expert evidence
62 To discharge his evidentiary onus, Mr Garlett was examined and
assessed by Dr Victoria Pascu who prepared reports dated
24 November 202319 and 25 March 2026.20 Mr Garlett also agreed to
an examination by Dr Adam Brett, who was engaged by the State
to provide an opinion as to Mr Garlett's capacity, as set out in his report
dated 23 December 2025.21 Both psychiatrists gave evidence at trial,
supplementing their respective reports.
63 In forming their respective assessments, both doctors interviewed
Mr Garlett. Mr Garlett elected not to give evidence at trial and,
accordingly, the statements he made to the examining doctors were not
confirmed on oath. In some instances, the doctors also obtained
collateral information from individuals closely associated with
Mr Garlett or previously involved in his treatment. Necessarily,
in reaching their opinions, each doctor relied to some extent on
statements that might otherwise be characterised as hearsay.
64 The way hearsay statements by an accused to a medical
practitioner may be received and used was usefully summarised by
Hall J (as his Honour then was) in The State of Western Australia v
Quartermaine.22 I adopt his Honour's analysis for the present matter.
65 For the most part, it appears the reliance placed upon what
Mr Garlett said during his examinations by both Dr Pascu and Dr Brett
was directed to the fact that the statements were made, rather than to
their truth. In relation to the majority of the history he provided,
this appears to have been corroborated by the extensive medical
records, themselves admissible pursuant to s 79C of the EA,
and tendered as part of the prosecution brief.23

[2026] WADC 45 [JM] Page 26
66 However, to the extent that the doctors relied on statements made
by Mr Garlett that were not confirmed on oath and were therefore
strictly hearsay, no objection was taken to those statements being
received as evidence of their truth.24 On that basis, the statements are
admissible and may operate as a 'medium of proof' with the question of
hearsay going to weight rather than admissibility.25
67 The opinions of Dr Pascu and Dr Brett were largely aligned,
differing only on the issue of capacity. Even in that regard, and for the
reasons discussed in greater detail below, the extent of their
disagreement was largely immaterial.
Did Mr Garlett have a mental impairment?
68 Both doctors diagnosed Mr Garlett with chronic,
treatment-resistant paranoid schizophrenia, a condition classified by
psychiatrists as a 'major mental illness'.26
69 The condition first emerged around 2017 - 2018, following the
death of his grandfather, after which his mental health began to decline.
Stress, including the stress from grief, is recognised as a factor that can
trigger or worsen psychotic symptoms.27
70 Prior to the onset of his illness, Mr Garlett was able to participate
normally in school, employment, and social activities. After the
condition developed, his behaviour altered, with reduced motivation,
increased depressive features, and a diminished capacity for initiative.
This presentation is consistent with the functional impairments
commonly associated with the 'negative symptoms' of schizophrenia.28
71 Other negative symptoms may include blunted affect and reduced
facial expression, both of which were visibly present in Mr Garlett,
as well as impaired logical thinking,29 although there was less evidence
of the latter.30
72 Following the onset of his condition in 2018, Mr Garlett attended
the Bentley Community Mental Health Clinic regularly from 2019
onwards, except for the period between 2021 and 2022 when his

compliance with treatment became more problematic. Apart from that
interval, he was generally compliant with treatment, receiving care in
the community through a combination of oral (olanzapine) and
injectable (paliperidone) antipsychotic medications administered on a
four‑weekly basis.31
73 Despite his compliance with treatment, Mr Garlett's condition
remained treatment-resistant. His medication served only to suppress,
rather than eliminate, his symptoms,32 and he continued to experience
residual symptoms even while medicated. These symptoms tended to
worsen toward the end of each treatment cycle, during which he
experienced 'breakthrough' symptoms.33
74 Medical records indicate that Mr Garlett received a depot injection
of 150 mg of paliperidone on 17 April 2023.34 The offending the
subject of counts 1 - 5 occurred on 20 April 2023. At that time,
Mr Garlett was under the care of the Bentley Community Mental
Health Clinic. In relation to the offending the subject of counts 6 - 8,
which occurred on 25 May 2024, his most recent documented depot
injection prior to those events was administered on 30 April 2024.35
At that time he was under the care of the Armadale Community Mental
Health team.
75 In addition to the negative symptoms outlined at [70] and [71],
individuals with schizophrenia may also experience 'positive
symptoms', including hallucinations, which are false perceptions of
stimuli that are not present,36 and delusions, being fixed false beliefs.37
When both are present, hallucinations may reinforce delusions,
intensifying their severity and increasing the likelihood that the
individual will act on those distorted beliefs.38
76 Mr Garlett has a documented history of exhibiting both
hallucinations and delusions. The most recent recorded instance of
delusional thinking prior to the offending on 20 April 2023 occurred on
2 November 2022, when he presented to the Bentley Community

Mental Health Clinic triage reporting paranoid beliefs that individuals
in cars were following him.39
April 2023 offending
77 Mr Garlett explained that, in the lead‑up to the offending on
20 April 2023, his mental health had been deteriorating, and he was
experiencing auditory hallucinations. Unlike in 2018, following the
death of his grandfather, and in January 2024, following the death of
his father, there was no clear precipitating event for the onset of his
psychosis on this occasion. Nevertheless, he described delusional
beliefs involving a stone and a USB both of which were said to hold
particular spiritual significance. He also reported paranoid beliefs that
he was being followed, including perceptions of people tailgating him,
together with concerns for the safety of his family.40
78 Independent evidence was available to Dr Brett and Dr Pascu
capable of corroborating Mr Garlett's account of the symptoms he was
experiencing. Although he did not participate in a formal electronic
record of interview, audiovisual evidence was available in the form of
body-worn camera footage capturing his interaction with the arresting
officers.41
79 Having reviewed that footage, it depicts Mr Garlett appearing to
respond to non‑existent stimuli, suggestive of hallucinations,
and demonstrating delusional beliefs regarding the attending officers'
purported level of knowledge of, and familiarity with, him. In fact,
neither officer had any prior involvement with Mr Garlett. The erratic
nature of his interactions with the officers is also detailed in the
statements provided by each officer, which were tendered as part of
the prosecution brief.42
80 Following Mr Garlett's arrest, he was taken into custody allowing
for further observations as to his behaviour. On 22 April 2023 he was
seen to be smiling inappropriately and he reported experiencing
auditory command type hallucinations. He was provided with a depot
injection on 15 May 2023.
81 He remained in custody until his release on bail on 19 December
2023. During this period, he continued to exhibit ongoing psychotic

symptoms and, notwithstanding the administration of regular depot
injections, continued to experience chronic residual symptoms which
persisted even after release to bail.
May 2024 offending
82 Following his release from custody, Mr Garlett's father died
suddenly of heart failure in January 2024. As noted, stress is a
well-recognised factor in precipitating the onset or exacerbation of
psychotic symptoms in schizophrenia, and this event is identified as a
trigger for the subsequent worsening of his pre-existing condition.
83 He was reviewed on 23 February 2024 at Armadale Community
Mental Health, where he was observed to be experiencing persecutory
delusions. At that time, the frequency of his depot injections had been
increased to every three weeks, with the most recent injection prior to
the offending administered on 30 April 2024. As can be seen at the
time of the offending on 25 May 2024, he was overdue for a further
depot injection.
84 Mr Garlett's account of this offending indicates that he was
experiencing visual hallucinations, including seeing spirits, as well as
persecutory, command-type auditory hallucinations. He also described
operating under persecutory delusions that he perceived as posing a
threat to his family.43
85 There was less independent corroborative evidence of Mr Garlett's
behaviour at the relevant time, however, two of the complainants
affected by his offending described him as appearing to be under the
influence of alcohol and/or drugs, given the erratic nature of his
conduct.44
86 Following his arrest and being taken into custody he was reported
to have made threats to kill himself. He was also observed to be
behaving extremely erratically and in a way that suggested he was
extremely unwell.45 On 12 June 2024 he reported he was continuing to
hear voices.
87 Mr Garlett has continued to remain in custody. During his
incarceration, his mental health has reportedly fluctuated, with ongoing
episodes of psychosis despite his continued compliance with treatment.

Analysis and findings
88 I am satisfied that Mr Garlett has suffered from schizophrenia
since 2018 and continues to do so. I am further satisfied that his
condition constitutes a 'major mental illness' and amounts to a 'disease
of the mind' as discussed above at [61] and therefore meets the
definition of a mental impairment for the purposes of s 1(1) of
the Code.
89 Since commencing treatment in 2019, the condition has proven to
be resistant. Over time, it has progressed to a stage where it may
appropriately be characterised as chronic paranoid schizophrenia.
90 Despite his compliance with treatment, and notwithstanding that
he had received a depot injection only three days before the April
offending, Mr Garlett continued to experience persistent breakthrough
symptoms, including auditory and visual hallucinations and related
delusions that were mutually reinforcing.
91 In relation to the April offending, there is evidence that Mr Garlett
continued to experience symptoms as at November 2022, together with
contemporaneous evidence in the form of body-worn camera footage
indicating that he remained symptomatic at the time of the offending.
This is further supported by evidence of his behaviour immediately
following his arrest and during his remand in custody, which suggests
an ongoing symptomatic state.
92 On the basis of the above, and consistently with the opinions
expressed by Dr Brett and Dr Pascu, I am satisfied that, at the time of
committing the offences the subject of counts 1 - 5, Mr Garlett was
more likely than not operating in a psychotic state arising from his
pre-existing mental illness of chronic paranoid schizophrenia.
93 In relation to counts 6 - 8, I am satisfied that the death of
Mr Garlett's father precipitated an exacerbation of his pre-existing
schizophrenia, leading to a progressively deteriorating mental state and
culminating in the offending on 25 May 2024. The behaviour
described by witnesses as 'intoxicated' or 'drug affected' is consistent
with the erratic presentation of a person experiencing psychosis.
This conclusion is further supported by the markedly psychotic
behaviours observed following his arrest and during his custody.
94 Similarly, and again in accordance with the opinions of Dr Brett
and Dr Pascu, I am satisfied that it is more likely than not that
-- 30 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 31
Mr Garlett was in a psychotic state at the time of committing the
offences the subject of counts 6 - 8, brought about by a deterioration in
his schizophrenic illness.
95 Accordingly, I am satisfied that at the time of committing each of
the offences with which he has been charged, Mr Garlett was operating
under a mental impairment.
Was Mr Garlett's disordered mind caused by voluntary intoxication?
96 Where a person's mind is disordered due to intentional intoxication
or stupefaction, s 28(2) of the Code operates to preclude the application
of s 27. Section 28(2) will not apply where an accused can prove that
at the time of doing the act or making the omission:46
(a) the accused suffered from a 'mental impairment', as defined in
s 1(1), independently of and without regard to the accused's
intoxication or stupefaction; and
(b) at the time of doing the relevant act or making the relevant
omission, the accused was in such a state of 'mental
impairment', as defined in s 1(1), as to deprive him or her of at
least one of the capacities referred to in s 27(1), independently
of and without regard to the accused's intoxication or
stupefaction.
97 Mr Garlett has an extensive history of illicit substance use.
He reports first using substances at the age of 23 (in 2016). At the time
of his grandfather's death in 2017 when the condition first manifested,
he was using cannabis regularly, at times up to 10 times per day.47
98 Further, Mr Garlett demonstrated an understanding of how alcohol
and illicit substances impacted his condition, noting that 'they made the
psychosis worse'. This response indicates that he recognised the role
his substance use played in contributing to his illness.48
99 Notwithstanding that insight, between 2021 and 2022, he began
using methylamphetamine. This period of use coincided with his
disengagement from the community mental health services responsible
for overseeing his treatment. Both Dr Brett and Dr Pascu expressed the
46 Stefanski v The State of Western Australia [2022] WASCA 5 (Stefanski).

48 Exhibit 7.1, par 28.
-- 31 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 32
opinion his illicit substance use during this period was very likely to
have contributed to the decline in his mental health at that time.49
100 In the first interview conducted with Dr Pascu, Mr Garlett stated
that he was unwell and could not recall using cannabis or any other
illicit substances in the lead-up to, or on the day of, the alleged
offences.50 Subsequently, in the course of preparing her second report,
Mr Garlett denied any use of alcohol or illicit substances prior to and
including the day of the 'alleged offences'.51 In this context,
the reference to the 'alleged offences' appears to relate to the offending
said to have occurred in May 2024.
101 During his interview with Dr Brett, Mr Garlett's denial appeared to
go further, in that he denied using any illicit substances at the time of
the offending in both April 2023 and May 2024,52 and claiming he had
not used illicit substances since October 2022.53
102 However, that claim appears to be inconsistent with an entry in
Dr Brett's report noting that clinical records from Mr Garlett's
attendance at the Bentley Community Mental Health Clinic on
2 November 2022 indicate that, at that time, he admitted to using
marijuana and methylamphetamines 'heavily'.54
103 Dr Brett also referred in his report to an entry in the prison notes
dated 14 August 2023,55 though this in fact appears to be a reference to
an entry made on 4 August 2023, which reads:56
He denies any current illicit substance use. States he has not used since
April 20th 2023. Reports recreational use in the community.
104 When questioned about this entry, Dr Brett confirmed it had been
forwarded to the Office of the Director of Public Prosecutions.
He further stated that there did not appear to be any additional
documentation capable of corroborating the reliability of what
Mr Garlett was reported to have admitted on 4 August and, to his
knowledge, no drug testing was conducted on or around 20 April 2023

to determine whether Mr Garlett was affected by drugs.
That understanding is correct, no such testing was carried out.
105 Notably, on 30 May 2024 during a search of the house where
Mr Garlett was living, smoking implements, namely a 'bong' and a
'meth pipe', were found in his bedroom and a quantity of cannabis was
also located elsewhere in the premises.57 Despite these indicia,
Mr Garlett maintained he was not using illicit substances at the relevant
time and asserted that the bong was used for smoking tobacco.58
106 Notwithstanding that this evidence may suggest that Mr Garlett
was using illicit substances at or around the time of his offending, and
that such use could potentially have contributed to a disordered state of
mind, the State's position is there is no evidence capable of positively
establishing that Mr Garlett was intentionally under the influence of
intoxicating substances at the relevant time. Nor does the State appear
to contend that any alleged admissions by Mr Garlett to that effect are
sufficiently reliable to support a finding that he was so intoxicated.
107 Accordingly, the State's position, as outlined, is that it does not
positively contend that I should be satisfied, on the balance of
probabilities, that s 28(2) of the Code operates to preclude any excuse
from criminal responsibility under s 27.59
108 The evidential burden of proof rests with the accused, first,
to displace the presumption of sanity under s 26 and, secondly,
to establish that s 28(2) does not apply. That evidential burden of proof
is that of the civil standard of 'balance of probabilities'.

109 However, as Heydon J observed (in dissent) in Strong v
Woolworths,60 the expression 'evidential burden' can be a source of
confusion, as it may be used in at least three distinct senses:
a persuasive burden, a 'provisional' or 'tactical' burden, and a 'prima
facie inference' burden arising where, in the absence of evidence to the
contrary, the trier of fact would err in failing to find in favour of
the party bearing it. This latter category may, in some circumstances,
risk being perceived as a reversal of the evidentiary onus.
110 In Taylor v The Queen61 Smithers J was of the opinion that a jury
should not reject or ignore unchallenged medical opinions that are
accepted as being honest and competent unless:
… the facts on which the medical witnesses have relied to form their
opinions are not satisfactorily established or are contradicted by other
acceptable evidence, or the jury are not persuaded that steps of
reasoning in the formation of those opinions were soundly taken,
or there is some other factor before them reflecting on the validity of
the opinions expressed …
111 Subject to the overarching caution outlined in Hone, the reasoning
in Taylor indicates an accused may still fail to discharge their evidential
burden even where the prosecution adduces no rebuttal evidence.
This tends to suggest that an accused's evidential burden is something
more than the kind Heydon J characterised as the 'prima facie inference'
burden and certainly more than the mere 'persuasive burden' referred to
in Strong.
112 The statements by Dixon J in Porter that 'it is necessary for the
accused person to make out positively, upon a balance of probability',
that it is sufficient if the matter is made to appear 'more probable on the
whole' and that the burden is one of 'establishing to [the trier of fact's]
reasonable satisfaction, not to the exclusion of all doubt, but on the
balance of probability', suggest a standard of the kind later described by
Dixon J in Briginshaw v Briginshaw.62 That standard was one
described as requiring 'actual persuasion' of the occurrence or existence
of the matter in question, rather than a conclusion based on the 'mere
preponderance of evidence'. This reflects what is commonly described
as the first aspect of the 'Briginshaw standard'.
60 Strong v Woolworths Limited [2012] HCA 5; (2012) 246 CLR 182 [46] - [64] (Strong).
61 Taylor v The Queen (1978) 45 FLR 343, 352 (Taylor).
62 Briginshaw v Briginshaw [1938] HCA 34; (1938) 60 CLR 336 (Briginshaw).
-- 34 of 41 --

ASTILL DCJ
[2026] WADC 45 [JM] Page 35
113 Dixon J went on to observe that the seriousness of the allegation
made and the gravity of the consequence flowing from a particular
finding were relevant considerations when determining whether the
evidential burden had been discharged. This forms the second part of
the Briginshaw standard.
114 However, in Briginshaw the seriousness of the allegation and the
gravity of the consequence to which Dixon J referred arose in
the context of establishing allegations of moral or criminal wrongdoing.
When Dixon J's explanation in Porter for the justification of the
insanity defence at common law is taken into account in assessing
the seriousness and gravity of the allegation, the operation of the
second aspect of the Briginshaw standard becomes less cautionary than
it would otherwise be when applied to allegations of moral or criminal
wrongdoing.
115 This suggests that the evidential burden borne by the accused is
more appropriately characterised as the 'provisional' or 'tactical' kind
described by Heydon J, in that it may impose a tactical burden on the
prosecution to adduce evidence in rebuttal. However, subject to
the caution expressed in Hone, a failure by the prosecution to do so
does not compel acceptance of the accused's evidence or a finding that
the evidential onus has been discharged.
116 It remains incumbent upon the accused to positively persuade the
trier of fact of the occurrence or existence of the matter in question.
In this context, having regard to the interpretation of the interaction
between s 27 and s 28(2) of the Code in Stefanski, the relevant
'occurrence or existence' is that s 28(2) does not apply. Accordingly,
an accused occupies the somewhat unusual position of bearing an
evidential burden to establish the absence of a particular state of affairs,
namely, that they were not intoxicated at the relevant time or,
if intoxicated, that such intoxication did not contribute to their
incapacity, irrespective of whether the prosecution advances a positive
contrary assertion.
117 In the present matter, at first glance, Mr Garlett's alleged
admissions to others regarding illicit substance use, particularly what he
is recorded as having said on 4 August 2023 in the prison notes
concerning use on the day of the offending on 20 April 2023,
together with the presence of drug-related indicia at his home on
30 May 2024, can appear somewhat compelling.
-- 35 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 36
118 In making that assessment, it is necessary to take into account that
no analysis appears to have been undertaken of the residue within the
smoking component of the implement to contradict Mr Garlett's
assertion that it was used for tobacco. Accordingly, the strength of any
finding depends entirely upon the reliability and acceptance of
Mr Garlett's alleged admissions, in circumstances where there is no
contemporaneous material capable of corroborating those admissions.
Given the State has elected not to test or otherwise establish the
reliability of those admissions, caution should be exercised before
accepting such untested statements from a person who was, at the
relevant time, experiencing psychosis.
119 Further, although Dr Brett was neither asked for, nor expressed, an
opinion on the issue, Dr Pascu considered that, even if Mr Garlett had
used illicit substances, his disordered mental state and the consequent
offending were not the result of voluntarily induced intoxication but
were instead attributable to his pre‑existing mental illness. Her opinion
was that to the extent illicit substances may have been present in his
system, they would have operated only to exacerbate his psychotic
symptoms, with the underlying psychosis arising independently of,
and not by reason of, any voluntary intoxication. There is no reason for
me not to accept that opinion.
120 On the basis of the analysis set out above, I am satisfied that
Mr Garlett has discharged his burden of positively establishing that,
in the present matter, s 28(2) of the Code does not operate to preclude
the application of s 27.
Did Mr Garlett's mental impairment deprive him of his capacity?
121 To be relieved of the criminal responsibility for his offending,
Mr Garlett must prove that his mental impairment deprived him of any
one of the following three capacities:
(a) to understand what he was doing;
(b) to control his actions; or
(c) to know that he ought not to do the act or make the omission.
122 Both Dr Brett and Dr Pascu expressed the opinion that
Mr Garlett's mental impairment did not deprive him of the capacity to
understand what he was doing. That issue therefore requires no further
consideration.
-- 36 of 41 --
[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 37
123 The two doctors also agreed that, by reason of his mental
impairment, Mr Garlett was deprived of the capacity to know that he
ought not to do the act or make the omission. This forms the principal
basis upon which it is contended that Mr Garlett should be excused
from criminal responsibility for his offending.
124 The only point of divergence between Dr Brett and Dr Pascu
concerned whether Mr Garlett's mental impairment deprived him of the
capacity to control his actions. Dr Brett considered that Mr Garlett's
capacity was impaired, but not deprived, whereas Dr Pascu was of the
view that his capacity was in fact deprived.
Capacity to control actions
125 A person lacks the capacity to control their actions if, due to a
mental impairment, they are unable to make a conscious decision to
perform the relevant act or to exercise a genuine power of choice in
acting. However, a person is not to be regarded as lacking such
capacity merely because their ability to resist an impulse or emotion is
significantly impaired.63
126 The expression 'capacity to control' in s 27(1) of the Code directs
attention to a person's ability either to choose to act or to refrain from
acting. A person lacks that capacity if they are unable to make a
conscious, voluntary decision to act, or unable to hold back or restrain
themselves from carrying out an intended act.
127 Where a mental impairment deprives a person of the ability to
refrain from acting, so that they no longer have a real power of choice,
they are, for that reason, deprived of the capacity to control their
actions within the meaning of s 27(1). This is so even if the act appears
deliberate or is carried out following a conscious decision.64
128 In determining whether a person's capacity to control their actions
was affected, it will often be necessary to consider the extent to which
any delusions or hallucinations influenced their conduct or undermined
their ability to choose whether to act.65

[2026] WADC 45
ASTILL DCJ
[2026] WADC 45 [JM] Page 38
Capacity to know that one ought not to do the act
129 A person will lack the requisite understanding of the wrongness or
nature of their act if, by reason of a disease, disorder, or defect of mind,
they were at the relevant time incapable of rationally reasoning with a
moderate degree of sense and composure about the act, such that they
could not appreciate its nature or that it was wrong according to the
ordinary standards of reasonable people.66
130 No material distinction exists between the common law test
articulated in Stapleton and s 27 of the Code. The question of whether
an act is right or wrong is to be made by reference to an objective
standard. The relevant inquiry is whether the accused was deprived of
the capacity to reason as to what was, by that objective standard,
right or wrong.67
131 In making the assessment, I must be cognisant that conduct which
might ordinarily indicate understanding in a person of sound mind,
such as awareness that an act was legally punishable, may not do so
where the accused, by reason of mental impairment, lacked the capacity
for rational reasoning.68
Analysis and findings
132 To the extent that there was a divergence between the opinions of
Dr Brett and Dr Pascu regarding Mr Garlett's capacity to control his
actions, both acknowledged that this was an area inherently
'controversial'69 and one where a difference in their respective opinions
was not unusual.70
133 Broadly, the difference in opinion may be characterised as a
divergence in subjective assessment between what constitutes
compulsion and what amounts to inducement. Dr Pascu was of the
opinion that auditory command hallucinations directing a person to act
amounts to a deprivation of the capacity to control one's actions.71
134 In contrast, Dr Brett considered that such hallucinations reflect a
delusional influence that may lead a person to act in a manner they
otherwise would not, but do not amount to a deprivation of the capacity

for control.72 In this respect, Dr Brett characterised the distinction as
one between an irresistible impulse, denoting a lack of capacity to
control, and an impulse not resisted, being conduct undertaken in
response to an inducement that might otherwise have been resisted.73
135 The divergence in opinion reflects an underlying tension between
the concepts of 'deprivation', being the absence of voluntariness,
and 'restraint', being the capacity to exercise choice, when applied to
the notion of performing a willed act, as those concepts were identified
by Derrick J in The State of Western Australia v Taylor74 and how
they relate to this capacity. However, given the consensus between
Dr Brett and Dr Pascu regarding Mr Garlett's incapacity to know that he
ought not to do the act, it is a tension that I ultimately do not need to
resolve.
136 Notwithstanding that, at various points during the offending,
Mr Garlett appeared to act in a goal-directed and rational manner,
for example, in the way he conducted himself when committing count 1
as described at [23(4)] - [23(7)], such outward behaviour was not
regarded as inconsistent with him being in a psychotic state and
operating under a delusional framework that impaired rational
thought.75 What is of primary significance is the presence of an
irrational mind, rather than whether a logical connection can be
discerned between the purported delusional framework and the person's
behaviour.76
137 Further, although there may be no immediately apparent logical
connection between the delusional framework under which Mr Garlett
reported he was operating and his actions and behaviour, reasoning of
that kind risks adopting the improper approach discussed above at
[131].
138 Nevertheless, broadly speaking, Mr Garlett's delusional beliefs as
amplified by his auditory hallucinations were that he believed his
family was at significant risk, people were following him and wanting
to do him harm and he was experiencing command hallucinations
telling him to attack.77 The significance of that delusional system lies
not in the possibility that it may have furnished Mr Garlett, in his own

mind, with a moral, albeit deluded, justification for his actions,
but rather in the fact that, in that context, his psychotic and disordered
state rendered him incapable of reasoning about his conduct with a
moderate degree of sense and composure.78
139 In circumstances where there is concurrence in the opinions that,
by reason of Mr Garlett's mental impairment, he was experiencing
paranoid delusions and command auditory hallucinations which
impaired his ability to reason with a moderate degree of sense and
composure as to what was right or wrong according to ordinary
standards, it would be inappropriate to disregard that evidence
capriciously. No proper basis has been identified for doing so.
140 Accordingly, I accept the opinions of Dr Brett and Dr Pascu and
am satisfied, on the balance of probabilities, that at all relevant times
Mr Garlett's mental impairment deprived him of the capacity to know
that he ought not to do the act or make the omission that would
otherwise render him criminally responsible.
Verdicts and consequential orders
141 In respect of each of the eight counts alleged against him, I find
Cyril Benedict Garlett not guilty by reason of mental impairment and
enter verdicts of acquittal pursuant to s 146 of the CPA in relation to
each count.
142 Having entered verdicts of acquittal pursuant to s 146, it is now
necessary, by operation of s 149(1) of the CPA and s 44(1) of the
CLMIA, to make an order under pt 5 of the CLMIA. I will do so after
receiving further submissions from the parties.
