General information, not legal advice.
Supreme Court of WA

Original judgment source is linked above.
(1) This section applies if an offender who is subject to a supervision order is before the Supreme Court and proceedings on an application made under section 53 in respect of the offender are pending (the pending proceedings).
(2) The court may at any time in the pending proceedings -
(a) if the offender is detained in custody, order the offender to be released, subject to subsection (3); or
(b) if the offender is not detained in custody, order the offender to be detained in custody.
(3) The court cannot order the offender to be released unless it is satisfied on the balance of probabilities that -
(a) releasing the offender is justified by exceptional circumstances; and
(b) the offender will substantially comply with the standard conditions of the supervision order, including any amendments to the standard conditions made under subsection (7)(b).
(4) The onus of proof as to the matter described in subsection (3)(b) is on the offender.
(5) For the purposes of subsection (3), in considering whether releasing the offender is justified by exceptional circumstances the court may, as it thinks fit, receive and take into account information put before it, whether or not that information would normally be admissible in a court of law.
(6) In making a decision under subsections (2) and (3), the paramount consideration is to be the need to ensure adequate protection of the community.
(7) If the court releases the offender -
(a) the offender remains subject to the supervision order; and
(b) the court may, before the pending proceedings are determined, make an interim order amending the supervision order to include any requirements the court considers appropriate to ensure adequate protection of the community; and
(c) the court may order the offender to reappear before the court at any adjourned hearing of the pending proceedings; and
(d) if it is alleged that the offender has further breached the supervision order or breached an order made under paragraph (c), the court may issue a warrant to have the offender arrested and brought before the court.
Prima facie, in my view, 'detained in custody', within the meaning of s 56, means detained pursuant to the provisions of the Act. Section 56(2)(a) cannot be construed as providing this Court with a general dispensing power to release persons who are otherwise in custody, either as sentenced prisoners or on remand for other offences. In the context of pt 4 div 5 of the Act, in my view, the expression 'detained in custody' would ordinarily apply to a person who is in custody as a consequence of having been arrested pursuant to a warrant issued under s 51 of the Act in relation to a suspected or anticipated contravention of a supervision order. An order of the Court would be necessary to 'release' such a person from custody, and so s 56(2)(a) would apply - including the requirements of s 56(3).
Similarly, a person detained pursuant to an order of the Court made under s 53(2)(b) of the Act would be 'detained in custody' within the meaning of s 56(2)(a).
An issue which arises in this case is whether the requirement for exceptional circumstances in s 56(3) is engaged in relation to the State's application. That, in turn, depends upon whether s 56(2)(a) is engaged.
...
Similarly, a person detained pursuant to an order of the Court made under s 53(2)(b) of the Act would be 'detained in custody' within the meaning of s 56(2)(a).
As a consequence of McGrath J's orders made on 9 December 2021, therefore, Mr Slater is, while that order remains in effect, 'detained in custody' within the meaning of s 56(2)(a). For that reason, if it was proposed that there be an order for Mr Slater to be released now (i.e. prior to 17 December 2021), it would be necessary for me to be satisfied that the requirements of s 56(3) are met, including that there exist exceptional circumstances and that he would substantially comply with the standard conditions of the interim supervision order.
However, once McGrath J's order for interim detention expires tomorrow, Mr Slater will be entitled to be released. No order is required for Mr Slater to be released at that point. In that case, there would not need to be, nor would there be an 'order [for] the offender to be released' within the meaning of s 56(2)(a) and that subsection would have no application. For that reason, the requirement in s 56(3) that there be exceptional circumstances would not apply either. Again, that is because there is no need for any order that Mr Slater be released for him to be released on 17 December 2021; the current order (of McGrath J) will simply have run its course.
This is why the State seeks an order under s 53(2)(b) of the Act. For Mr Slater to be further detained after 17 December 2021 it would be necessary for me to make a positive order to that effect under s 53(2)(b). That power to order further detention is not one affected by s 56(2)(a).
Accordingly, I propose to consider the State's application on the basis that it is an application that I make a positive order under s 53(2)(b). For that reason, no issue of exceptional circumstances arises.
[T]he real issue is that which applies generally to an interim detention order (under s 46(2)(c)) or an interim supervision order under (s 58(2)(c)); namely, whether the Court is satisfied that, to ensure adequate protection of the community, it is desirable to make either an interim detention order or an interim supervision order. That is, in effect, the test that applies to the making of an interim supervision order generally.
This points up an important aspect of any consideration of alleged contraventions of an interim supervision order. Compliance with an interim supervision order (and, indeed, any supervision order) is an important matter, and the importance of such compliance should not be understated. Nevertheless, it must be recognised, having regard to the text and structure of the Act as a whole, that an interim supervision order is not an end in, and of, itself. An interim supervision order is a means to an end: the end being the protection of the community against the risk of serious offences.
In that sense, a supervision order or an interim supervision order will have served its purpose if it protects the community from serious offences, even if compliance with the conditions of the order, in the particular case, has not been perfect. The Court must always keep in mind that the object of the Act to be achieved is the adequate protection of the community from the commission of serious offences.
Assessment of the application made under s 53(2)(b) of the High Risk Serious Offenders Act
(a) the evidence available with respect to the circumstances in which the contravention offences were committed while the respondent was subject to the supervision order (which the State suggested demonstrated a level of disregard for the conditions of the supervision order and a continued sexual preoccupation with children);[7]
(b) the State's submission that the risk of the respondent committing a serious offence was heightened in circumstances where no suitable accommodation was available, particularly when regard was had to the previous evidence of Dr Wynn Owen in relation to imminence of reoffending in circumstances where there was a lack of suitable accommodation;[8]
(c) that there appeared to be good reason for the authorities to be concerned about their ability to manage the respondent in the community given the absence of suitable accommodation; and
(d) that on the evidence before the Court, particularly the evidence of there being no stable accommodation, I could not be satisfied on the balance of probabilities that the respondent would substantially comply with the standard conditions of the supervision order, including any amendments to the standard conditions made under subsection (7)(b).
I certify that the preceding paragraph(s) comprise the reasons for decision of the Supreme Court of Western Australia.
