The judges must be appointed by <answer>the president</answer> with the advice and consent of the Senate, hold office during good behavior and receive compensations that may not be diminished during their continuance in office. If a court's judges do not have such attributes, the court may not exercise the judicial power of the United States. Courts exercising the judicial power are called "constitutional courts."
