what is the job of the supreme court

The job of the Supreme Court of the United States is to serve as the highest tribunal in the nation for all cases and controversies arising under the Constitution or the laws of the United States. It 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 Court plays a crucial role in the constitutional system of government by exercising judicial review, which allows it to declare a legislative or executive act in violation of the Constitution. As the "court of last resort," the Supreme Court makes decisions that all other courts must follow, establishing legal precedents. The Court consists of the Chief Justice of the United States and eight Associate Justices, who are appointed by the President and confirmed by the Senate. The Supreme Courts authority to invalidate legislation or executive actions that conflict with the Constitution is a key aspect of its role in the American system of government.
