Article III, Section 1:
The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish. The 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.
Article III, Section 1 provides that federal judges hold their offices during good behavior.
1 This standard, borrowed from English law, ensures that federal judges hold their seats for life, rather than set terms or at the will of a superior.2 The applicability of the Good Behavior Clause to the removal of federal judges has been the subject of debate; in particular, whether the phrase elucidates a distinct standard for removal apart from the high crimes and misdemeanors
standard applicable to the impeachment of other federal officers.3 While this question has not been definitively resolved, historical practice indicates an understanding that the Good Behavior Clause protects federal judges from removal for congressional disagreement with legal or political opinions.4
