There shall be a Council to aid and advise in the government of the Irish Free State/Saorstat Eireann to be styled the Executive Council/Aireacht. The Executive Council shall be responsible to the Chamber/Dail Eireann, and shall consist of not more than twelve Ministers/Airi appointed by the Representative of the Crown, of whom four Ministers shall be Members of the Chamber/Dail Eireann and a number not exceeding eight, chosen from all citizens eligible for election to the Chamber/Dail Eireann, who shall not be members of Parliament/Oireachtas during their term of Office, and who, if at the time of their appointment they are members of Parliament/Oireachtas, shall by virtue of such appointment vacate their seats; Provided that the Chamber/Dail Eireann may from time to time on the motion of the President of the Executive Council determine that a particular Minister or Ministers not exceeding three, may be members of Parliament/Oireachtas in addition to the four members of the Chamber/Dail Eireann above mentioned. ARTICLE 51. The Ministers who are required to be members of the Chamber/Dail Eireann shall include the President of the Executive Council/Uachtaran and the Vice-President of the Executive Council/Tanaist. The President of the Executive Council shall be the chief of the Executive Council and shall be appointed on the nomination of the Chamber/Dail, and the Vice-President of the Executive Council and the other Ministers who are members of Parliament/Oireachtas shall be appointed on the nomination of the President of the Executive Council; and he and the Ministers nominated by him shall retire from office should he fail to be supported by a majority in the Chamber/Dail, but the President of the Executive Council and such Ministers shall continue to carry on their duties until their successors are appointed. ARTICLE 52. Ministers who are not members of the Parliament/Oireachtas shall be nominated by a Committee of members of the Chamber/Dail Eireann chosen by a method to be determined by the Chamber/Dail so as to be impartially representative of the Chamber/Dail. Such Ministers shall be chosen with due regard to their suitability for office and should as far as possible be generally representative of the Irish Free State/Saorstat Eireann as a whole rather than of groups or of parties.
