Clause 155

Where a person subject to military law is on board a ship, this Act shall apply until he arrives at the port of disembarkation in like manner as if he and the officers in command of him were on land at the place at which he embarked on board the said ship:Provided that if he is tried and sentenced while so on board a ship, any finding and sentence, so far as not confirmed and executed on board the said ship, may be confirmed and executed in like manner as if such person had been tried at the port of disembarkation.

Where the officer commanding the troops on board a ship holds an authority empowering him during the voyage to convene a court-martial for the trial of any person under his command who is subject to military law and to confirm the finding and sentence of a court-martial convened for the trial of any such person as aforesaid, or conferring on him either of those powers, that authority shall, in relation to any such person as aforesaid, have effect as if it had been issued at the place where that person embarked on board the said ship by an officer or person qualified under this Act to issue such an authority at that place.
