A further notable change took place at the same time. The Mutiny Act had been brought into force on each occasion for one year only, in compliance with the constitutional theory:
that the maintenance of a standing army in time of peace, unless with the consent of parliament, is against law. Each session therefore the text of the act had to be passed through both Houses clause by clause and line by line. The Army Act, on the other hand, is a fixed permanent code. But constitutional traditions are fully respected by the insertion in it of a section providing that it shall come into force only by virtue of an annual act of parliament. This annual act recites the illegality of a standing army in time of peace unless with the consent of parliament, and the necessity nevertheless of maintaining a certain number of land forces (exclusive of those serving in India) and a body of royal marine forces on shore, and of keeping them in exact discipline, and it brings into force the Army Act for one year.
