Courts of Argentina

A federal country with two sets of courts: federal courts, and the courts of each province and of the city of Buenos Aires. Any judge can decide a constitutional question, and the Supreme Court has the last word.

Appeals travel up the arrows. Boxes with a heavier border are the top court of each track.

Worth knowing

  • There is no separate constitutional court. Any judge can refuse to apply a law that breaks the Constitution, and the Supreme Court decides in the end.
  • A national Council of the Judiciary (Consejo de la Magistratura) helps choose and discipline federal judges.
