Article III of the U.S. Constitution

Article III of the U.S. Constitution establishes the judicial branch of government. It creates the Supreme Court and allows Congress to set up lower courts. It defines the powers of federal courts, including resolving disputes involving the Constitution, federal laws, or treaties. It outlines the jurisdiction of federal courts, the tenure of judges (they serve for life unless they misconduct), and specifies the types of cases they can hear. It also grants the authority to try cases of impeachment and sets the standards for conduct and trial procedures for federal judges. Overall, it ensures an independent judiciary to interpret and uphold the law.
