The State of Western Australia v Alvisse

The State of Western Australia brought proceedings against Alvisse under the Dangerous Sexual Offenders Act 2006 (WA), seeking a continuing detention order. The dispute centred around the assessment of Alvisse's risk to the community and the appropriate legal measures to mitigate that risk. The Supreme Court of Western Australia was tasked with deciding whether Alvisse constituted a serious danger to the community, and if so, whether a continuing detention order was necessary or if an amended supervision order would suffice.

The central legal issue before the court was whether the evidence supported a finding that Alvisse posed a serious danger to the community, thereby justifying a continuing detention order. The court also had to consider whether, in light of the evidence, an amended supervision order could adequately manage the risk posed by Alvisse. The assessment of risk involved evaluating the likelihood of Alvisse contravening any supervision order, as well as the potential consequences of such contravention.

The court found that while Alvisse did pose a serious danger to the community, the evidence did not conclusively indicate that he would contravene a supervision order. It was determined that an amended supervision order, with specific conditions and monitoring, could effectively manage the risk. The court emphasised the importance of balancing the need to protect the community with the rights of the individual, and concluded that an amended supervision order was a proportionate response. The court thus rejected the application for a continuing detention order and instead made an amended supervision order.
