Attorney-General (SA) v Moyle

In the Supreme Court of South Australia, the case of Attorney-General (SA) v Moyle [2018] SASC 43 involved a critical examination of whether the respondent, Mr. Moyle, should be subject to an indefinite detention order due to his persistent exhibitionist behaviour and risk of reoffending. The Attorney-General sought this order under the Serious or Violent Offenders or Dangerous Sexual Offenders Act 2006 (SA), arguing that Mr. Moyle posed a significant risk to the community if released. The primary legal issues before the court were whether Mr. Moyle had a significant risk of reoffending and whether this risk warranted the imposition of an indefinite detention order under the Act.

The court considered various psychiatric and psychological evaluations, including those by Dr. Lim and Dr. Haeney. Dr. Lim concluded that Mr. Moyle exhibited cognitive distortions and limited empathy, suggesting he was unwilling to control his sexual instincts, which supported the Attorney-General's application. However, Dr. Haeney opined that while Mr. Moyle's risk of committing a sexual offence involving personal contact was not negligible, it was not significant. The court weighed these expert opinions and concluded that, despite the risk, Mr. Moyle's repeated instances of indecent behaviour and masturbation in institutional settings did not necessarily indicate a significant risk of committing serious sexual offences in the community. The court also noted that there was no evidence of Mr. Moyle committing sexual assaults on staff members while in custody.

Ultimately, the court determined that while Mr. Moyle's risk of reoffending was a concern, it was not sufficiently grave to justify the exceptional sanction of indefinite detention. The court exercised its discretion to refuse the Attorney-General's application, finding that the risk of Mr. Moyle committing an offence such as indecent behavior or gross indecency, if the opportunity arose, did not warrant the imposition of an indefinite detention order.
