What it does
The High Risk Serious Offenders Act 2020 establishes a statutory regime in Western Australia for identifying, detaining indefinitely, or supervising offenders who the court finds to present an unacceptable risk of committing a further serious offence. The Act creates two primary restriction orders: continuing detention orders, which detain an offender in custody for an indefinite term for control, care or treatment (s 26(1)), and supervision orders, which subject an offender, when not in custody, to stated conditions including reporting, electronic monitoring and curfews (s 27(1); s 30(2)(a)-(g)). The court must give detailed reasons when making a restriction order (s 28).
Mechanically, the Act sets a substantive threshold and an evidentiary regime for the State to obtain those orders. An offender is a "high risk serious offender" if the court is satisfied, by acceptable and cogent evidence and to a high degree of probability, that a restriction order is necessary to ensure adequate protection of the community against an unacceptable risk that the offender will commit a serious offence (s 7(1)). The State bears the onus of proof (s 7(2)). The court must disregard the possibility that the offender might be temporarily prevented from committing a serious offence by imprisonment, remand in custody, or bail conditions (s 7(4)).
The Act creates institutional supports and procedural steps. It establishes a High Risk Serious Offenders Board with coordination, advisory and best‑practice functions (s 14-15). It requires cooperation and information-sharing between supporting agencies and provides legal protection for good‑faith disclosures between them (s 24-25). It provides for a preliminary hearing to test whether reasonable grounds exist to proceed to a full hearing (s 46). If the court so directs at the preliminary stage, the offender must undergo psychiatric and psychological examination and the CEO engages qualified experts to prepare independent reports (s 46(2)(a); s 67(1); s 74).
