The Supreme Court of the United States is the highest court in the federal judiciary of the United States. Established pursuant to Article III of the U.S. Constitution in 1789, it has original jurisdiction over a narrow range of cases, including suits between two or more states and those involving ambassadors. It also has ultimate (and largely discretionary) appellate jurisdiction over all federal court and state court cases that involve a point of federal constitutional or statutory law. The Court has the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution or an executive act for being unlawful. The Court's rulings have a profound impact on American society and the Court itself is steeped in tradition and history.
