How long do Supreme Court justices serve?

Supreme Court justices serve for life, unless they choose to resign or are removed from office through the impeachment process. This lifetime appointment is designed to ensure that justices are independent from political pressures and can make decisions based on their interpretation of the law rather than concerns about reelection or job security. This permanence allows justices to maintain judicial integrity and uphold the Constitution without external influences. The provision for lifetime tenure reflects the framers' intention to create a stable judiciary that could withstand changes in political climates and remain a check on power. As such, the other choices, which propose limited terms or reappointment situations, do not reflect the established structure of the Supreme Court in the United States.
