Lockwood v The Commonwealth

In the High Court of Australia, Rupert Ernest Lockwood sought to challenge the validity of a Royal Commission appointed to inquire into espionage and related activities in Australia. The commission, comprising three commissioners, was established by letters patent issued by the Governor-General. Lockwood, who had been subpoenaed to appear before the commission and was the subject of allegations concerning certain documents, argued that the commission's appointment and terms of reference were invalid. He also sought to restrain the commission from proceeding with its inquiry into matters that were the subject of a defamation action he had commenced against the Commonwealth and counsel assisting the commission.

The legal issues before the Court included whether the Royal Commission was exercising judicial power, whether the appointment of three commissioners was valid given that the Royal Commission Act 1954 appeared to authorise only a single commissioner, and whether the inclusion of the word "unlawfully" in the letters patent rendered them invalid. Further issues concerned the validity of the commission's inquiry into matters that were the subject of pending litigation, and whether the commission's terms of reference were sufficiently connected to Commonwealth power.

Fullagar J. held that the commission did not exercise judicial power, as its function was to inquire and report, not to decide or determine legal rights. While the Royal Commission Act 1954 appeared to authorise only a single commissioner, the appointment of three commissioners was found to be valid under the broader provisions of the Royal Commissions Act 1902-1933. The Court also determined that the word "unlawfully" in the letters patent should be read in accordance with the Acts Interpretation Act 1901-1950 to mean "contrary to the laws of the Commonwealth," thus not invalidating the commission's terms of reference. Finally, the Court ruled that the existence of pending defamation proceedings did not prevent the commission from continuing its statutory inquiry, as statutory authority overrides common law principles that might otherwise suggest a stay.

Consequently, the Court dismissed Lockwood's application for an injunction and declared that the commission was entitled to proceed with its inquiry.
