Cabinet collective responsibility

Cabinet collective responsibility, also known as collective ministerial responsibility, is a constitutional convention in governments using the Westminster System that members of the cabinet must publicly support all governmental decisions made in Cabinet, even if they do not privately agree with them. This support includes voting for the government in the legislature. Some Communist political parties apply a similar convention of democratic centralism to their central committee. If a member of the cabinet does wish to openly object to a cabinet decision then they are obliged to resign from their position in the cabinet.

Cabinet collective responsibility is related to the fact that, if a vote of no confidence is passed in parliament, the government is responsible collectively, and thus the entire government resigns. The consequence will be that a new government will be formed, or parliament will dissolve and a general election will be called. Cabinet collective responsibility is not the same as individual ministerial responsibility, which states that ministers are responsible and therefore culpable for the running of their departments.

Cabinet collective responsibility is a tradition in parliamentary governments in which the prime minister is responsible for appointing the cabinet ministers. The cabinet ministers are usually selected from the same political party as the prime minister to make collective decision-making for legislation faster and more effective. Unlike a presidential system, as used, for example, in the United States, a parliamentary system’s executive and legislative branches are intertwined. Because of the fusion of powers of the executive and legislative branches the prime minister relies on the cabinet to always support their policy decisions. A breach of cabinet collective responsibility, such as when a cabinet member publicly disagrees with an executive decision results in a resignation or termination from that cabinet position. The New South Wales Parliamentary Library Research Service in Australia explains that "one aspect of collective ministerial responsibility is that Ministers share responsibility for major government decisions, particularly those made by the cabinet and, even if they personally object to such decisions, Ministers must be prepared to accept and defend them or resign from the cabinet".
