(a) neuropsychological report of Dr Liz Vuletich, dated 11 September 2025; and
(b) psychiatric report of Dr Gosia Wojnarowska, dated 17 September 2025.
(a) to ensure the protection of the community;[17]
(b) to ensure persons with mental impairment who are charged with an offence are dealt with fairly and with dignity;[18] and
(c) to ensure that persons who are subject to supervision orders under the CLMI Act are afforded procedural fairness in relation to the administration and management of those orders and are reintegrated into the community in a safe manner.[19]
(a) the extent to which the freedom of a person with a mental impairment may be curtailed;[21]
(b) the fair, appropriate, supportive and dignified treatment of persons with a mental impairment;[22]
(c) the manner in which the CLMI Act should be administered in respect of children with a mental impairment;[23]
(d) recognising that victims of offences committed by persons with mental impairment should have the opportunity to be acknowledged and heard;[24] and
(e) recognising the role of carers and families who assist persons with mental impairment.[25]
Before making an extended custody order, the court must be satisfied, by acceptable and cogent evidence and to a high degree of probability, that, to ensure the adequate protection of the community against an unacceptable risk that the supervised person will commit a serious offence, it is necessary to make an extended custody order in respect of the supervised person.
[T]he question of whether a person 'will commit a serious offence' is assessed by reference to whether the person will do an act, or make an omission, that would constitute a serious offence, irrespective of whether the person has sufficient mental capacity to be criminally responsible for that act or omission. Thus, in making the assessment, the court does not take into account the prospect that the person might be found not guilty of the 'serious offence' under s 27 of the Code. This approach accords with an object, and the paramount consideration, of the CLMI Act being the protection of the community. That object and paramount consideration would be significantly eroded if the assessment of the risk the person will 'commit' a serious offence took into account whether the person would have sufficient mental capacity to be criminally responsible for their conduct.
Such an approach is also supported by s 11(1) of the CLMI Act, which states:
A reference in this Act to the commission of an offence includes, in relation to a person who has been acquitted of the offence on account of mental impairment, a reference to the doing of the act or the making of the omission that would have constituted the offence of which the person was acquitted. (emphasis added)
Even though s 11(1) is directed to historical offending, it recognises that in respect of the 'commission of an offence', the concern of the CLMI Act is directed to 'the doing of the act or the making of the omission that would have constituted the offence', not to whether the person has the requisite mental capacity to be criminally responsible for that act or omission.
Further, s 110(6) and s 110(7) are to the effect that in considering whether an act or omission committed outside the State constitutes a serious offence, the court is to disregard whether the person would be fit to stand trial, or convicted of the offence.[32]
(1) whether there is an unacceptable risk that the supervised person will engage in conduct, by act or omission, that constitutes a serious offence, regardless of their mental capacity and criminal responsibility; and
(2) if such a risk exists, whether making an ECO is necessary to adequately protect the community against that risk.
(a) the protection of the community;
(b) the nature of the offence and the circumstances of its commission;
(c) the person's character, antecedents, age and health;
(d) the nature of the person's mental impairment;
(e) the relationship between the mental impairment and the offending conduct
(f) the degree of risk that the person appears to present to themself or the safety of the community because of their mental impairment;
(g) the extent to which adequate resources are available for the treatment, care and support of the person in the community;
(h) if the person is a child - the child-specific considerations; and
(i) if the person was a child at the time of the commission of the offence - the general principles of juvenile justice set out in the Young Offenders Act 1994 (WA) s 7.
[T]he possible serious offences that might be committed and the harm they may cause. It also directs attention to the likelihood that the offender might commit such offences (that is, the likelihood the risk might eventuate). The extent to which deterrent factors have operated to reduce risk in the past is relevant to the assessment of current and future risk, as is the offender's historical and current response to rehabilitation. These are all factors that inform the assessment of whether the risk is 'unacceptable', but they are not exhaustive.[33]
[The respondent] presents a chronically moderate risk of violent and sexual offending, and he is likely to reoffend with a return to substance use or absence of order.
As evidenced in this report, [the respondent's] risk of violence is likely to significantly increase if he were discharged from the custody order into the community. It is my opinion that [the respondent] would not be suitable for long-term psychiatric inpatient treatment if he were discharged from his custody order as his primary issues relate to his intellectual disability and organic brain disorder, of which the state's psychiatric inpatient services are ill-equipped to manage. Considering the above, I do not recommend [the respondent] is discharged from his extended custody order at this time but continuous efforts to transition him to the community as per his management plan should remain in place.[106]
