History: The Court was created in 1801 with both Federal and state-level jurisdiction for the District of Columbia. The Court's state-level jurisdiction was transferred to the District of Columbia Court of Appeals in 1970, but the Circuit Court's decisions prior to 1971 still have precedential value in state-level D.C. courts.
