Officers' Commissions Act 1862

The Officers' Commissions Act 1862 (25 & 26 Vict. c. 4) was an Act of Parliament of the Parliament of the United Kingdom.

It provided that any officer's commission in the British Army could be issued without the royal sign-manual, provided that it was signed by a principal secretary of state and the commander in chief, or an appropriate officer depending on the specific branch of service. For the Royal Marines, a signature from the Admiralty was required.

The act, whilst amended to reflect changes in the military and political structure since 1862, is still in force.
