United States Court of Appeals for the Third Circuit

The United States Court of Appeals for the Third Circuit (in case citations, 3d Cir.) is a federal court with appellate jurisdiction over the district courts for the following districts:
 * District of Delaware
 * District of New Jersey
 * Eastern District of Pennsylvania
 * Middle District of Pennsylvania
 * Western District of Pennsylvania

This circuit also hears appeals from the District Court of the Virgin Islands, which is an Article IV territorial court and not a district court under Article III of the Constitution.

The court is composed of 14 active judges and is based at the James A. Byrne United States Courthouse in Philadelphia, Pennsylvania. The court also conducts sittings in other venues, including the United States Virgin Islands. It is one of 13 United States courts of appeals. Due to the court's appellate jurisdiction over Delaware, where more than half of publicly-traded companies in the United States incorporate, the court handles a significant number of influential commercial cases in the United States.
