The Supreme Court consists of the Chief Justice of the United States and such number of Associate Justices as may be fixed by Congress. The number of Associate Justices is currently fixed at eight (28 U. S. C. §1). Power to nominate the Justices is vested in the President of the United States, and appointments are made with the advice and consent of the Senate. Article III, §1, of the Constitution further provides that "[t]he Judges, both of the supreme and inferior Courts, shall hold their Offices during good Behaviour, and shall, at stated Times, receive for their Services, a Compensation, which shall not be diminished during their Continuance in Office."
The Federal Judicial Center is the research and education agency of the judicial branch of the U.S. government. The Center was established by Congress in 1967 (28 U.S.C. §§ 620–629). The Center's governing board is chaired by the Chief Justice of the United States. The other Board members are seven judges elected by the Judicial Conference of the United States, and the Director of the Administrative Office of the U.S. Courts.
