As a result, Alfonsín sponsored the Trial of the Juntas, in which, for the first time, the leaders of a military coup in Argentina were on trial. The first hearings began at the Supreme Court in April 1985 and lasted for the remainder of the year. In December, the tribunal handed down life sentences for Jorge Videla and former Navy Chief Emilio Massera, as well as 17-year sentences for Roberto Eduardo Viola. President Leopoldo Galtieri was acquitted of charges related to the repression, but he was court-martialed in May 1986 for malfeasance during the Falklands War. Ramón Camps received a 25-year sentence. The trials did not focus only on the military: Mario Firmenich was captured in Brazil in 1984 and extradited to Argentina. José López Rega was extradited from Miami in 1986, because of his links with the Argentine Anticommunist Alliance.
