U.S. District Courts

The United States District Courts are the general trial courts of the federal judiciary, created under Article III of the U.S. Constitution and established by congressional statute to serve as the primary forums for adjudicating federal disputes. There are 94 judicial districts, including at least one in each state, the District of Columbia, and various U.S. territories, each functioning as a court of original jurisdiction in civil and criminal matters arising under federal law. District courts have authority to hear a broad range of cases, including prosecutions for federal crimes, civil actions involving federal statutes or the Constitution, diversity jurisdiction cases between citizens of different states where the amount in controversy exceeds the statutory threshold, and suits in which the United States is a party. Each district court is staffed by judges appointed by the President with Senate confirmation, serving lifetime tenure during good behavior, and supported by magistrate judges who handle certain preliminary proceedings and specialized matters by delegation. District courts operate with juries in both civil and criminal trials where constitutionally or statutorily required, and they also serve as the trial-level courts for specialized units such as U.S. Bankruptcy Courts, which are constituted as adjuncts of the district courts under Article I authority. Decisions from district courts are subject to review by the U.S. Courts of Appeals for their respective circuits. As the entry point into the federal judicial system, district courts function as the foundation of federal adjudication, ensuring the application of federal law and the protection of constitutional rights in trial proceedings.
