Are US Supreme Court decisions final?

The Supreme Court's decisions are always final unless they agree to rehear a case, which rarely happens. The Supreme Court is the final authority on federal and constitutional law in the United States; there is no further avenue of appeal.

There are only two ways in which a Supreme Court decision may be overturned: 1) the Court may change its own decisions; 2) Congress and the states may effectively overrule a decision by constitutional amendment. In the case of nullified federal laws, Congress may rewrite the law to comply with constitutional requirements.
