Members of the Supreme Court are appointed for life.
The Court is composed of a president (Chief Justice) and eight associate judges (Associate Justices), who are appointed by the president of the United States and confirmed by the "advice and consent" of the United States Senate. The appointed judges of the court serve for life and can only be removed by Congress through a process of impeachment. Judges may resign from their office of their own volition. No judge has been removed from office, although many have withdrawn or resigned.
