A before and after is marked after the approval of the Legal System and the State Administration Act (LRJAE) of 1957 that develops the principle of Unity of Administration and places the Council of Ministers as the supreme and central body of the Administration, regulating the Government under the name of Council of Ministers and equipping it with Delegated Committees of the Government to deal with minor issues between ministries. At that time the Secretary of the Council of Ministers was the Minister-Under Secretary of the Presidency.
