what is supreme court

The Supreme Court of the United States is the highest tribunal in the nation for all cases and controversies arising under the Constitution or the laws of the United States. It consists of the Chief Justice of the United States and eight Associate Justices, whose number is fixed by Congress. The Court is charged with ensuring the American people the promise of equal justice under law and functions as the guardian and interpreter of the Constitution. The best-known power of the Supreme Court is judicial review, which allows the Court to declare a Legislative or Executive act in violation of the Constitution. The Court has ultimate appellate jurisdiction over all federal court cases and over state court cases that involve a point of U.S. Constitutional or federal law. The Supreme Court plays a crucial role in the constitutional system of government, and its decisions have a significant impact on the interpretation and application of the law in the United States.
