Article III describes the court system (the judicial branch), including the Supreme Court. The article describes the kinds of cases the court takes as original jurisdiction. Congress can create lower courts and an appeals process, and enacts law defining crimes and punishments. Article Three also protects the right to trial by jury in all criminal cases, and defines the crime of treason.
Section 1 vests the judicial power of the United States in federal courts, and with it, the authority to interpret and apply the law to a particular case. Also included is the power to punish, sentence, and direct future action to resolve conflicts. The Constitution outlines the U.S. judicial system. In the Judiciary Act of 1789, Congress began to fill in details. Currently, Title 28 of the U.S. Code describes judicial powers and administration.
As of the First Congress, the Supreme Court justices rode circuit to sit as panels to hear appeals from the district courts. In 1891, Congress enacted a new system. District courts would have original jurisdiction. Intermediate appellate courts (circuit courts) with exclusive jurisdiction heard regional appeals before consideration by the Supreme Court. The Supreme Court holds discretionary jurisdiction, meaning that it does not have to hear every case that is brought to it.
To enforce judicial decisions, the Constitution grants federal courts both criminal contempt and civil contempt powers. Other implied powers include injunctive relief and the habeas corpus remedy. The Court may imprison for contumacy, bad-faith litigation, and failure to obey a writ of mandamus. Judicial power includes that granted by Acts of Congress for rules of law and punishment. Judicial power also extends to areas not covered by statute. Generally, federal courts cannot interrupt state court proceedings.
Clause 1 of Section 2 authorizes the federal courts to hear actual cases and controversies only. Their judicial power does not extend to cases that are hypothetical, or which are proscribed due to standing, mootness, or ripeness issues. Generally, a case or controversy requires the presence of adverse parties who have some interest genuinely at stake in the case.
