's Cabinet, 1981]]
Under the doctrine of [[separation of powers]], a cabinet under a [[presidential system]] of government is part of the executive branch. In theory, at least, they carry out policy rather than create it. In addition to administering their respective segments of the executive branch, cabinet members are responsible for advising the head of government on areas within their purview. They are appointed by and serve at the pleasure of the head of government and are therefore strongly subordinate to the president as they can be replaced at any time. Normally, since they are appointed by the president, they are members of the same political party, but the executive is free to select anyone, including opposition party members, subject to congressional confirmation.
Normally, the legislature or a segment thereof must confirm the appointment of a cabinet member; this is but one of the many [[checks and balances]] built into a presidential system. The legislature may also remove a cabinet member through a usually difficult [[impeachment]] process.
