Three days after taking office, Alfonsín sent a bill to the Congress to revoke the self-amnesty law established by the military. This made it possible for the judiciary to investigate the crimes committed during the Dirty War. During the campaign, Alfonsín had promised that he would do this while Luder had been non-committal. Alfonsín also ordered the initiation of judicial cases against guerrilla leaders Mario Firmenich, Fernando Vaca Narvaja, Ricardo Obregón Cano, Rodolfo Galimberti, Roberto Perdía, Héctor Pardo and Enrique Gorriarán Merlo; and military leaders Jorge Videla, Emilio Massera, Orlando Agosti, Roberto Viola, Armando Lambruschini, Omar Graffigna, Leopoldo Galtieri, Jorge Anaya and Basilio Lami Dozo. He also requested the extradition of guerrilla leaders who were living abroad.
