R v Langdon; Ex parte Langdon

The High Court of Australia considered an application for a writ of habeas corpus brought by a husband, Mr Langdon, seeking the return of his infant child. The child had been taken by his wife to a different State. The wife, in turn, had made an application for custody and maintenance of the child.

The central legal issue before the Court was whether a State court, exercising special jurisdiction conferred by State law concerning infants, had the power to grant custody of a child to a parent who had removed the child from the matrimonial home and taken them to another State, thereby potentially interfering with the jurisdiction of the court of the matrimonial home.

The Court reasoned that the writ of habeas corpus was a fundamental common law remedy designed to secure the liberty of the subject and was not intended to be used as a means of enforcing custody rights in matrimonial disputes, particularly where the child was not being unlawfully detained. The Court distinguished the present situation from cases where a writ of habeas corpus might be appropriate, such as where a child was being detained by a stranger. The Court emphasised that the State legislation conferring special jurisdiction on State courts with respect to infants did not override the common law principles governing the writ of habeas corpus.

The High Court discharged the order nisi for the writ of habeas corpus.
