Rule nisi for a writ of habeas corpus or in the alternative for a writ of prohibition. It was obtained by two members of the naval forces of the Commonwealth, which form part of the defence force of the Commonwealth (Defence Act 1903-1941, sec. 30; Naval Defence Act 1910-1934, Part III.), who had been convicted of the murder of a stoker of the naval forces of the Commonwealth, by a court-martial which purported to have been assembled pursuant to the provisions of the Naval Defence Act 1910-1934 of the Commonwealth (See secs. 5 and 36) and the Imperial Naval Discipline Act 1866 (29 and 30 Vict. c. 109) and sentenced to be hanged on board such one of His Majesty's Australian ships and at such time as the Board of Administration for the Naval Forces should direct. The murder was committed on an Australian ship of war on the high seas, but the court-martial was assembled and held on that ship in a port in the South Pacific that was not a British port. On 22nd April 1942 warrants were issued by the captain and commanding officer of that ship to the Officer-in-Charge of the State Penitentiary at Long Bay, Sydney, New South Wales, to receive and keep the men so convicted in his custody, but directed that the sentence was not to be carried out until further directions were given. Pursuant to the warrant the men are now in custody at the Long Bay Penitentiary at Sydney. The validity of this warrant was not challenged upon the argument before this Court, but I have not, myself, been able to trace its authority. The Naval Discipline Act 1866, Part V., does not appear to authorize it. The Order-in-Council regulating courts-martial and the King's Regulations require the convening authority, that is, the officer authorized pursuant to the Naval Discipline Act 1866, sec. 58 (9), (12), to order courts-martial, to appoint a provost marshal, who is required to take the accused into his custody and safely to keep him until he shall have been delivered in due course of law. So soon as the court-martial is dissolved the president is to wait upon the Commander-in-Chief or senior officer with a letter reporting the finding and sentence. The Commander-in-Chief or senior officer must satisfy himself of the validity of the finding before he takes any step to give effect to the sentence, as by the issue of a warrant for imprisonment or detention. When sentence of death is to be executed the Commander-in-Chief or the convening authority gives direction as to the time, place and manner in which such sentence is to be carried out. No sentence of death passed by a court-martial can be carried into effect until confirmed by the Admiralty or by the Commander-in-Chief on a foreign station: See Order in Council, 11th October 1923, Statutory Rules and Orders (1923), p. 659 (1923 1291/L 20); King's Regulations 1936, "Explanation of Terms" p. xi., and ch. IX., Court-Martial, clauses 439 (2), 471 (2), (3), 471 (a); Naval Discipline Act 1866 (29 & 30 Vict. c. 109), sec. 53 (3). The Naval Discipline Act 1866, the Naval Discipline (Dominion Naval Forces) Act 1911 and the King's Regulations and Admiralty Instructions for the time being in force, apply to the naval forces of the Commonwealth subject to the Act and to any modifications and adaptations prescribed by regulations (Naval Defence Act 1910-1934, sec. 36). But no sentence of death passed by any court-martial governed by the Defence Act 1903-1941 can be carried into effect until confirmed by the Governor-General (Defence Act 1903-1941, sec. 98; Naval Defence Act 1910-1934, sec. 5).
