The United States Court of Appeals for the District of Columbia Circuit (in case citations, D.C. Cir.) is one of the thirteen United States Courts of Appeals. It has the smallest geographical jurisdiction of any of the U.S. courts of appeals, covering only the U.S. District Court for the District of Columbia. It provides appellate review of cases from that district court and federal administrative agency cases, including federal regulatory actions and constitutional challenges. It meets at the E. Barrett Prettyman United States Courthouse at 333 Constitution Ave NW, Washington, DC 20001.
