Queensland v Mr Stradford (a pseudonym)

The High Court of Australia considered appeals from decisions of the Federal Court concerning the imprisonment of Mr Stradford. Mr Stradford had been declared in contempt and sentenced to imprisonment by a judge of the Federal Circuit Court. This declaration and sentence were subsequently set aside by the Full Court of the Family Court due to a lack of power and a failure to afford procedural fairness. Mr Stradford then sued the judge for false imprisonment, and the Commonwealth and Queensland for vicarious liability. The primary judge found the judge liable for false imprisonment, holding that the imprisonment order and warrant were invalid due to jurisdictional error, and that the judge had lost judicial immunity. The primary judge also found that the Commonwealth and Queensland were liable, rejecting their defence that their officers acted in reliance on a facially regular warrant.

The legal issues before the High Court included whether the imprisonment order and warrant issued by the Federal Circuit Court were valid unless and until set aside, as contended by the Commonwealth under s 17 of the Federal Circuit Court of Australia Act 1999 (Cth). The Court also had to determine the scope of common law judicial immunity from civil suit for acts done in the exercise of a judicial function, particularly in light of the jurisdictional errors made by the Federal Circuit Court judge. Furthermore, the Court considered whether persons acting in reliance on the imprisonment order and warrant, despite their invalidity, were liable to Mr Stradford, and whether s 249 of the Criminal Code (Qld) provided a defence to the Queensland police and correctional officers.

The High Court allowed the appeals, setting aside the orders of the Federal Court. The Court held that the orders of the Federal Circuit Court, including the contempt declaration and imprisonment order, were valid and had full force and effect unless and until they were set aside. This was based on the interpretation of s 17 of the Federal Circuit Court of Australia Act 1999 (Cth), which provided that such orders were valid unless and until set aside. Consequently, the imprisonment of Mr Stradford was lawful. The Court found that the primary judge erred in concluding that the orders were invalid due to jurisdictional error and that the judge had lost judicial immunity. As the orders were valid, the defence of justification was available to the Commonwealth and Queensland, meaning their officers were not liable for false imprisonment.

The High Court ordered that the proceedings brought by Mr Stradford against the relevant respondents be dismissed. The costs of the appeals were to be paid by Mr Stradford to the respondents.
