KP v Minister for Mental Health

The applicant, KP, sought judicial review of decisions made by the Mental Health Review Tribunal concerning his detention and conditional release as a forensic patient. The dispute centred on the validity of the Tribunal's orders under the *Mental Health and Cognitive Impairment Forensic Provisions Act 2020* (NSW). The matter was heard by Basten AJA, Griffiths AJA, and Price AJA in the Court of Appeal of New South Wales.

The primary legal issues before the Court of Appeal were whether the Tribunal had the power to revoke KP's conditional release and whether its detention orders were validly made under sections 79 and 81 of the *Mental Health and Cognitive Impairment Forensic Provisions Act 2020* (NSW). The Court also considered the application of section 109 of the Act, which deals with the apprehension of forensic patients who breach their conditional release, and whether it provided a mandatory scheme in such circumstances.

The Court analysed the statutory provisions, particularly section 81, which grants the Tribunal power to make orders as to the detention of forensic patients. Applying the principle of statutory construction that express powers imply necessary ancillary powers, the Court concluded that the power to revoke a conditional release was implied from the express power of detention. The Court found that section 109, which provides for apprehension upon breach of conditional release, would be futile if the patient were already detained, suggesting it had a different, limited role.

Ultimately, while the Court granted KP an extension of time to commence proceedings and leave to appeal the Tribunal's orders of 9 January 2024, it dismissed the appeal itself. No order was made as to costs.
