A Department of State (Irish: Roinn Stáit) of Ireland is a department or ministry of the Government of Ireland. The head of such a department is a minister termed a Minister of the Government; prior to 1977 such ministers were called Ministers of State, a term now used for junior (non-cabinet) ministers.[1] Most members of the government are Ministers of the Government, though there may occasionally be a minister without portfolio who does not head a department of state. The law regarding the departments of state and ministers of the government is based in the Constitution of Ireland, primarily in Article 28; legislative detail is given in the Ministers and Secretaries Acts 1924 to 2020.
