The Supreme Federal Court (Portuguese: Supremo Tribunal Federal, abbreviated STF) is the supreme court (court of last resort) of Brazil, serving primarily as the Constitutional Court of the country. It is the highest court of law in Brazil for constitutional issues and its rulings cannot be appealed. On questions involving exclusively lower legislation, the highest court is, by rule, the Superior Court of Justice. Alongside its appeal competence, mostly by the Extraordinary Appeal (Recurso Extraordinário), the Court has a small range of cases of original jurisdiction, including the power of judicial review, judging the constitutionality of laws passed by the National Congress, through a Direct Action of Unconstitutionality (Ação Direta de Inconstitucionalidade, or ADIn).
