The Arizona Supreme Court is the state supreme court of the U.S. state of Arizona. Sitting in the Supreme Court building in downtown Phoenix, the court consists of a chief justice, a vice chief justice, and five associate justices. Each justice is appointed by the governor of Arizona from a list recommended by a bipartisan commission. Justices stand for retention in an election two years after their appointment and then every six years.^[1] They must retire at age 70.

The Chief Justice is chosen for a five-year term by the court, and is eligible for re-election. They supervise the administration of all the inferior courts. They are Chairman of the Commission on Appellate Court Appointments, which nominates candidates to fill vacancies in the appellate courts. If the Governor fails to appoint one of the nominated candidates within sixty days of their names being submitted to her or him, the Chief Justice makes the appointment.

The Vice Chief Justice, who acts as Chief Justice in the latter's "absence or incapacity," is chosen by the court for a term determined by the court.^[2]

The jurisdiction of the court is prescribed by Article VI, Section 5 of the Arizona Constitution.^[3] Most of the appeals heard by the court go through the Arizona Court of Appeals, except for death penalty cases, over which the Arizona Supreme Court has sole appellate jurisdiction. The court also has original jurisdiction in a few other circumstances as outlined in the Arizona Constitution. A quorum is three, but the whole court must sit in order to declare a law unconstitutional.^[4]
