New South Wales v TD

The plaintiff, detained in prison, sought a writ of habeas corpus and damages for false imprisonment against the State of New South Wales. The plaintiff's detention in prison followed a District Court order authorising his detention in a hospital, made pursuant to the *Mental Health (Criminal Procedure) Act 1990* (NSW). The Court of Appeal considered the availability of habeas corpus and the tort of false imprisonment in these circumstances.

The central legal issues before the Court of Appeal were whether the plaintiff retained any residual liberty that could be vindicated by a writ of habeas corpus or an action for false imprisonment, given the District Court's order for hospital detention. The Court also had to determine the relationship between habeas corpus and false imprisonment, and whether the latter tort was available when a person was detained in the wrong place, rather than being detained without any lawful authority. The Court considered the effect of the District Court nominating a "limiting term" under the Act and whether the court retained a discretion to decline to make an order for custody after nominating such a term.

The Court of Appeal held that the writ of habeas corpus was not available to the plaintiff because the District Court's order for hospital detention, although not complied with by the prison authorities, constituted a lawful basis for detention. The Court reasoned that habeas corpus is concerned with the legality of detention, not the place of detention. Similarly, the tort of false imprisonment was not available as the plaintiff was not detained without lawful authority, but rather in the wrong place. The Court affirmed that the plaintiff's remedy lay in ensuring compliance with the court order for hospital detention, not in challenging the fundamental legality of his detention. The Court referred to and applied principles discussed in *R v AN (No 2)* [2006] NSWCCA 218; 66 NSWLR 523.

The Court of Appeal dismissed the appeal and ordered the appellant to pay the respondent's costs.
