The Federal Judicial System is the branch of the United States government responsible for interpreting laws and administering justice. It consists of three main levels: the Supreme Court, which is the highest court, followed by Courts of Appeals, and District Courts. Each level has specific roles in handling cases, with the Supreme Court primarily addressing significant legal questions and constitutional issues. Judges in the federal system are appointed by the President and confirmed by the Senate. They serve lifetime appointments, ensuring independence from political pressures. The system also includes specialized courts, such as the Tax Court and Bankruptcy Court, which handle specific types of cases.
