 When a case is brought before the Supreme Court, the justices may choose to send the case to one of the four divisions of the Civil Court of Appeals, of which two are located in Tulsa and two in Oklahoma City.Each division of the court has three judges; they are appointed for life, but they must stand for election every six years to retain their positions.Two of the three judges may choose to reaffirm, modify, or overturn any ruling of any lower court.
