The appointment of Supreme Court Justices in the United States is a lifetime appointment, as outlined in the Constitution. Justices serve for life unless they resign, retire, are impeached and convicted, or pass away. The intention behind lifetime appointments is to insulate the judiciary from political pressures, allowing justices to make decisions based on the law rather than concerns about reappointment or public opinion. This system is designed to promote judicial independence, but opinions on it may vary. Some argue that lifetime appointments contribute to stability and independence, while others suggest that fixed terms or mandatory retirement ages could bring more accountability and ensure fresh perspectives on the bench.
