8. Why does the Constitution give Justices lifetime tenure? So they are less subject to popular and political pressures.
13. Explain your answer to #8 using the definition of both original and appellate jurisdiction.
The constitution give life tenures because its main goal is to insulate the officeholder from external pressures. In common law legal systems original jurisdiction of a court is the power to hear a case for the first time, as opposed to appellate jurisdiction, when a higher court has the power to review a lower court's decision.
