Chapter II sets up the executive branch of government. Executive power is to be exercised by the Governor-General, advised by the Federal Executive Council. The Governor-General is the commander in chief. He or she may appoint and dismiss the members of the Executive Council, ministers of state, and all officers of the executive government. These powers, along with the powers to dissolve (or refuse to dissolve) parliament (Section 5, Section 57), are termed "reserve powers". The use of these powers is by convention. Generally, the Governor-General acts only on the advice of the Prime Minister. There has been only one instance of the Governor-General not taking the Prime Minister's advice. Governor-General Sir John Kerr, acting on his own, dismissed Prime Minister Gough Whitlam in the 1975 Australian constitutional crisis.
