In Louisiana, the judiciary has four general levels. The Mayor's Courts, Justices of the Peace Courts, City Courts, Parish Courts, and Family and Juvenile Courts are lower-level courts that focus on cases involving specific subject matter, such as traffic violations, small claims, and misdemeanor offenses. The District Courts are the trial courts of general jurisdiction, but can also have appellate jurisdiction over certain criminal cases tried by Mayor's, City, and Parish Courts, and some cases tried by Justice of the Peace Courts in parishes where no Parish Court exists. The Louisiana Courts of Appeal act as the intermediate appellate court. The Louisiana Supreme Court is the highest court in the state.
