Supreme Court of Pennsylvania

The Supreme Court of Pennsylvania is the highest court in the Commonwealth of Pennsylvania's Unified Judicial System. It also claims to be the oldest appellate court in the United States, a claim that is disputed by the Massachusetts Supreme Judicial Court. The Supreme Court of Pennsylvania began in 1684 as the Provincial Court, and casual references to it as the "Supreme Court" of Pennsylvania were made official in 1722 upon its reorganization as an entity separate from the control of the royal governor.
