The courts of the District of Columbia consist of Police Courts, a Supreme Court, and a Court of Appeals. The Supreme Court consists of a chief justice and five associate justices, each of whom individually holds court for the trial of law, equity, and criminal cases. Thence an appeal lies to the Court of Appeals composed of a chief justice and two associate justices. From the Court of Appeals in certain cases an appeal or writ of error lies to the Supreme Court of the United States.
