what article of the constitution established the supreme court
Article Three of the United States Constitution Article Three of the United States Constitution establishes the judicial branch of the federal government. The judicial branch comprises the Supreme Court of the United States and lower courts as created by Congress.
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.
