The U.S. District Court is a federal trial court in the United States where civil and criminal cases are heard. Each state has at least one district court, and larger states may have several. These courts handle a variety of cases, including those involving federal laws, disputes between states, and cases involving citizens from different states. Judges in the U.S. District Court are appointed by the President of the United States and confirmed by the Senate. The decisions made in these courts can be appealed to the U.S. Court of Appeals, which reviews the cases for legal errors.
