of June, the court releases orders and opinions beginning at 10am, and these 15 to 30-minute sessions are open to the public on a similar basis. Supreme Court Police are available to answer questions. Jurisdiction Congress is authorized by Article III of the federal Constitution to regulate the Supreme Court's appellate jurisdiction. The Supreme Court has original and exclusive jurisdiction over cases between two or more states but may decline to hear such cases. It also possesses original but not exclusive jurisdiction to hear "all actions or proceedings to which ambassadors, other public ministers, consuls, or vice consuls of foreign states are parties; all controversies between the United States and a State; and all actions or proceedings by a State against the citizens of another State or against aliens." In 1906, the court asserted its original jurisdiction to prosecute individuals for contempt of court in United States v. Shipp. The resulting proceeding remains the only contempt proceeding and only criminal trial in the court's history. The contempt proceeding arose from the lynching of Ed Johnson in Chattanooga, Tennessee the evening after Justice John Marshall Harlan granted Johnson a stay of execution to allow his lawyers to file an appeal. Johnson was removed from his jail cell by a lynch mob, aided by the local sheriff who left the prison virtually unguarded, and hanged from a bridge, after which a deputy sheriff pinned a note on Johnson's body reading: "To Justice Harlan. Come get your nigger now." The local sheriff, John Shipp, cited the Supreme Court's intervention as the rationale for the lynching. The court appointed its deputy clerk as special master to preside over the trial in Chattanooga with closing arguments made in Washington before the Supreme Court justices, who found nine individuals guilty of contempt, sentencing three to 90 days in jail and the rest to 60 days in jail. In all other cases, the court has only appellate jurisdiction, including the ability to issue writs of mandamus and writs of prohibition to lower courts. It considers cases based on its original jurisdiction very rarely; almost all cases are brought to the Supreme Court on appeal. In practice, the only original jurisdiction cases heard by the court are disputes between two or more states. The court's appellate jurisdiction consists of appeals from federal courts of appeal (through certiorari, certiorari before judgment, and certified questions), the United States Court of
