Criminal, civil, and small claims cases

Explanation:

The Supreme Court of the United States is the highest court in the United States of America. As such, the Court is the head of the Judiciary of the United States. The Court consists of a Chief Justice and eight Associate Justices, who are appointed by the President of the United States and confirmed by the "advice and consent" of the United States Senate. The appointed judges of the court serve for life and can only be dismissed by the Congress through an impeachment process. Judges can resign their position of their own accord. No judge has been removed from office, although many have retired or resigned. The Supreme Court is the only court established by the Constitution of the United States. All other courts have been created by Congress. The Court has the power of judicial review and the power to declare federal or state laws unconstitutional and acts of the federal and state executive powers. Your decisions cannot be appealed.
