Ex parte Williams

The applicant, Harold Roy Williams, sought a writ of habeas corpus from the High Court of Australia. This followed an earlier application for special leave to appeal to the High Court, which had been refused due to an equal division of opinion among the Justices. The dispute concerned the validity of an order made by the Court of Criminal Appeal of New South Wales, which had increased a sentence originally imposed on Williams by a New South Wales Court of Quarter Sessions for a federal offence.

The legal issues before the High Court were whether it had jurisdiction to grant a writ of habeas corpus in these circumstances, and if so, whether the applicant could succeed in challenging the order of the Court of Criminal Appeal. Specifically, the Court had to consider the effect of the equal division of opinion in the prior special leave application under section 23(2)(a) of the Judiciary Act 1903-1932, the extent to which a superior court's determination of its own jurisdiction could be challenged on habeas corpus, and whether a writ of habeas corpus was an appropriate remedy for a person in execution after a criminal judgment.

A majority of the High Court (Rich, Dixon, and McTiernan JJ.) held that the application should be refused. They reasoned that even if the order nisi were granted, the applicant would not succeed because the prior equal division of opinion meant the Court of Criminal Appeal's decision would stand under section 23(2)(a) of the Judiciary Act. Rich and Dixon JJ. further held that the Court of Criminal Appeal, as a superior court, was authorised to conclusively determine its own jurisdiction, rendering its order valid and unchallengeable on habeas corpus. Starke and Dixon JJ. also concluded that a writ of habeas corpus did not lie as the applicant was in execution after a criminal judgment. Starke J. additionally found the High Court lacked jurisdiction as the matter did not arise under the Constitution or involve its interpretation, while Evatt J. considered it futile to grant the order nisi given it would ultimately be discharged.

The application for an order nisi for a writ of habeas corpus was refused.
