Supreme Court of the United States - Decisions

The decisions of the Supreme Court, whether by a denial of certiorari or by an opinion issued following oral argument, are final and cannot be appealed. A Supreme Court decision based on an interpretation of the Constitution may be changed by constitutional amendment. Congress may modify a decision that is based on the interpretation of an act of Congress by passing a law that directs the Court as to congressional intent and purpose. However, Congress has no power to modify a High Court decision that is based on the Court's interpretation of the Constitution. Finally, the Court may overrule itself, although it rarely does so.
