The State of Western Australia v Narkle [No 6]

The State of Western Australia brought proceedings against Narkle under the Dangerous Sexual Offenders Act 2006 (WA) for contravention of a supervision order. Narkle had been placed on a supervision order following a conviction for a serious sexual offence. The dispute centred on whether Narkle's subsequent development of dementia affected the risk he posed to the community, and thus his continued need for supervision. The Supreme Court of Western Australia was tasked with determining whether the state had met its burden of proving that Narkle remained a significant risk to the community, despite his dementia.

The primary legal issue before the court was whether the respondent's dementia, which developed after the imposition of the supervision order, impacted the risk assessment required under the Act. The court had to consider whether the state had proven, on the balance of probabilities, that Narkle still posed a significant risk to the community and thus warranted continued supervision. This involved an analysis of the statutory criteria and case law interpreting the Act, alongside expert evidence on the impact of dementia on Narkle's risk of reoffending.

In its decision, the court held that Narkle's dementia did not absolve him of the risk he posed to the community. While acknowledging the changes dementia brought to Narkle's circumstances, the court found that the state had provided sufficient evidence to meet its burden of proof. The court relied on expert psychiatric evidence, which indicated that despite the dementia, Narkle retained the potential to commit serious sexual offences if left unsupervised. The court concluded that the state had satisfied the statutory criteria for continued supervision, and thus the contravention of the supervision order was justified in the interest of community protection.

The court ordered that Narkle remain subject to the supervision order and directed the Commissioner of Corrections to implement appropriate measures to ensure Narkle's compliance with the order. The court emphasised the importance of balancing the respondent's rights with the need to protect the community from potential harm. The decision underscored the court's role in ensuring that dangerous sexual offenders are appropriately managed and supervised, even in the face of significant medical changes.
