J, Compulsory Care recipient, by his welfare guardian T v Attorney-General

This case involved four separate proceedings before the High Court of New Zealand, challenging the detention of J, a care recipient with an intellectual disability, under the Intellectual Disability (Compulsory Care and Rehabilitation) Act 2003 (IDCCR Act). J, through his welfare guardian, his mother, sought a judicial review of his detention and the validity of his compulsory care orders. The proceedings were heard together, and the court considered the appeal, a Family Court appeal, an inquiry under section 102 of the IDCCR Act, and a judicial review. The court found that J's detention was lawful and not arbitrary, and that there was no breach of the New Zealand Bill of Rights Act 1990 (NZBORA) or any other errors of law. The court declined to grant declaratory relief, damages, or a stay of proceedings. The court also found that the destruction of the District Court criminal file was lawful. The court dismissed the Family Court appeal and declined to grant leave to appeal out of time. The court concluded that J's detention was justified due to his intellectual disability and the risk he posed to himself and others.
