The period of a supervision order under the HRSO Act should reflect the minimum intrusion on the offender's liberty necessary to ensure adequate protection of the community, assessed by reference to the period by which the offender will be able to make appreciable gains in rehabilitation and achieve some stability in the community. The court may find an unacceptable risk of committing a serious offence of a type the offender has not previously committed, where the offender's pattern of offending demonstrates conduct capable of causing such harm. The HRSO Act does not provide for regular reviews of supervision orders or a mechanism to shorten their period, which is a relevant factor in setting the order's duration.
