Note: Certiorari is one of the two ways to have a case from a U.S. Court of Appeals reviewed by the U.S. Supreme Court. Certification is the other. The Supreme Court may also use certiorari to review a decision by a state's highest court when there is a question as to the validity of a federal treaty or statute, or of a state statute on constitutional grounds. Certiorari is also used within state court systems.
