In the United States, most of the U.S. federal courts of appeal have adopted a rule under which, in the event of any conflict in decisions of panels (most of the courts of appeal almost always sit in panels of three), the earlier panel decision is controlling, and a panel decision may only be overruled by the court of appeals sitting en banc or by a higher court.[2] Other courts, for example, the Court of Appeals for the Federal Circuit (formerly known as Court of Customs and Patent Appeals) and the US Supreme Court, always sit en banc, and thus the later decision controls.[citation needed]
