Supreme Court of WA

Original judgment source is linked above.
(1) whether the respondent is a high risk serious offender, within the meaning of s 7 of the HRSO Act; and, if so
(2) whether to make an order that the respondent be detained in custody for an indefinite term for control, care or treatment (a continuing detention order)[2] or that he be released into the community subject to conditions that the court considers appropriate (supervision order).
(1) Psychiatric report of Professor Natalia Pyszora dated 4 January 2026; and
(2) Psychological report of Dr Tara Yewers dated 18 December 2025.
(a) to provide for the detention in custody or the supervision of high risk serious offenders to ensure adequate protection of the community and of victims of serious offences; and
(b) to provide for continuing control, care or treatment of high risk serious offenders.[12]
An offender is a high risk serious offender if the court dealing with an application under this Act finds that it is satisfied, by acceptable and cogent evidence and to a high degree of probability, that it is necessary to make a restriction order in relation to the offender to ensure adequate protection of the community against an unacceptable risk that the offender will commit a serious offence.
Whether or not a risk that an offender will commit a 'serious offence' is 'unacceptable' is a question which requires the court's judgment as to the nature and extent of the harm said to be in prospect. Further, whether a restriction order is 'necessary' to protect against that risk requires recognition of what would otherwise be the offender's entitlement to be at liberty, an entitlement not lightly to be denied.
In my view, an 'unacceptable risk' in the context of s 7(1) is a risk which is unacceptable having regard to a variety of considerations which may include the likelihood of the person offending, the type of sexual offence which the person is likely to commit (if that can be predicted) and the consequences of making a finding that an unacceptable risk exists. That is, the judge is required to consider whether, having regard to the likelihood of the person offending and the offence likely to be committed, the risk of that offending is so unacceptable that, notwithstanding that the person has already been punished for whatever offence they may have actually committed, it is necessary in the interests of the community to ensure that the person is subject to further control or detention.
[T]he court should choose, as between a continuing detention order and a supervision order, the order that is 'least invasive or destructive' of a person's right to be at liberty while ensuring an adequate degree of protection of the community. That constraint also applies in determining the non-standard conditions (if any) of a supervision order. Moreover, as Hall J pointed out in Director of Public Prosecutions v Decke,[26] '[i]t cannot simply be assumed that the most assured preventative is detention and therefore, the protection of the community will always favour such an order'.[27]
[t]he court must be satisfied that the respondent will comply with the standard conditions in a manner and to an extent that is consistent with and will enable the attainment of the general object of the supervision order and the legislation, namely the adequate protection of the community by management and mitigation of the risk that the respondent will commit a serious ... offence.[30]
Matters to be considered pursuant to s 7(3) HRSO Act Antecedents and criminal history
Reports prepared under s 74 for the hearing of the application and the extent to which the offender cooperated in the examination required by that section
Any other medical, psychiatric, psychological or other assessment relating to the offender
Propensity to commit serious offences in the future and whether or not there is any pattern of offending behaviour
Any efforts by the respondent to address the cause or causes of the offending behaviour, including whether the respondent has participated in any rehabilitation program, and whether the participation in any rehabilitation program has had a positive effect on the offender
(1) engaging with antisocial peers in the community;
(2) poor coping skills such as problem solving, communication and social skills;
(3) reliance on alcohol;
(4) not addressing his alcohol abuse when he is back in the community;
(5) holding on to resentment on what he missed out on while in prison; and
(6) the respondent's partner, who has a criminal record and substance abuse issues.
The risk that, if the offender were not subject to a restriction order, the offender would commit a serious offence and the need to protect members of the community from that risk
Is the respondent a high risk serious offender? Is there an unacceptable risk that the respondent will commit a serious offence?
Is it necessary to make a restriction order to ensure adequate community protection against the unacceptable risk that the respondent will commit a serious offence?
Continuing detention order or supervision order?
In choosing between an indefinite detention order or a supervision order, the fact that the paramount consideration is the need to ensure the adequate protection of the community does not exclude other considerations. The use of the word 'adequate' indicates that a qualitative assessment is required. In considering whether a supervision order would adequately protect the community, account must be taken of conditions which can be placed on a supervision order so as to ensure the adequate protection of the community, the rehabilitation of the respondent and his care and treatment. The Act does not require that there be no risk of reoffending. Such a requirement could never be met and would mean no person to whom the Act applies would ever be released. The question is whether the risk is reduced to a reasonably acceptable level that ensures adequate protection of the community. That requires a weighing of the nature and degree of risk in the context of methods for the management and reduction of that risk. If, after considering all the evidence, the court is left in doubt as to whether the conditions of a supervision order would adequately protect the community, because the paramount consideration is the need to ensure the adequate protection of the community, the court must expressly decline to rescind the continuing detention order.[222]
Has the respondent satisfied the court on the balance of probabilities that he will substantially comply with the standard conditions?
