A royal decree is synonymous with a presidential executive order— one that does not require a bill to be introduced in the parliament and subjected to scrutiny and debate. See "Legal Decree for the Delegation of Full Powers to Sir Majesty's Government for the Rearrangement of the Taxation System and of Public Administration," Law 1601, December 3, in GU 293 (December 15, 1922).
