State of New South Wales v Cornwall

The State of New South Wales filed an application for an interim detention order against Cornwall, who had been convicted of multiple sexual assaults between 1989 and 1993. Cornwall was under an existing extended supervision order and was due for release on 13 June 2015. Given his criminal history and mental health status, the State sought the order to ensure Cornwall would be admitted to Long Bay Mental Health Facility if not detained. Cornwall opposed the application and was, in fact, already admitted to a mental health facility. The court had to determine whether an interim detention order was warranted and, if so, what conditions should be imposed.

The primary legal issues revolved around the necessity and appropriateness of an interim detention order under the relevant mental health legislation. The court had to assess whether Cornwall posed a significant risk to the community or himself if not detained and if there were any suitable alternatives to detention. The court also had to consider the impact of an interim detention order on Cornwall’s rights and the proportionality of such an order. The application hinged on whether the potential benefits of detention outweighed the infringement on Cornwall’s personal freedoms.

The court found that while Cornwall's criminal history and current mental health issues warranted serious consideration, there were no immediate grounds to believe he posed a significant risk to the community or himself at the time of the hearing. The court emphasised that an interim detention order should only be made if it was necessary and proportionate to the circumstances. Given that Cornwall was already in a mental health facility, the court deemed an interim detention order unnecessary. The court dismissed the application for an interim detention order but appointed psychiatrists to monitor Cornwall's condition and report back.
