when does the supreme court use original jurisdiction
Procedures of the Supreme Court of the United States Certain cases that have not been considered by a lower court may be heard by the Supreme Court in the first instance under what is termed original jurisdiction. The Supreme Court's authority in this respect is also derived from Article III of the Constitution, which states that the Supreme Court shall have original jurisdiction "in all cases affecting ambassadors, other public ministers and consuls, and those in which a state shall be party." The original jurisdiction of the Court is set forth in 28 U.S.C. § 1251. This statute provides further that, in the case of disputes between two or more states, the Supreme Court holds both original and exclusive jurisdiction and no lower court may hear such cases.
Supreme Court of the United States The Supreme Court of the United States is the highest federal court of the United States. Established pursuant to Article Three of the United States Constitution in 1789, it has ultimate (and largely discretionary) appellate jurisdiction over all federal courts and state court cases involving issues of federal law plus original jurisdiction over a small range of cases. In the legal system of the United States, the Supreme Court is generally the final interpreter of federal law including the United States Constitution, but it may act only within the context of a case, in which it has jurisdiction. The Court does not have power to decide political questions, and its enforcement arm is in the executive rather than judicial branch of government.
