In Argentina, the CONADEP human rights commission of 1983, led by writer Ernesto Sabato and René Favaloro among other respected personalities, investigated human rights abuses during the dictatorship. The 1985 Trial of the Juntas convicted top officers who ran the military governments for acts of state terrorism. The amnesty laws (Ley de Obediencia Debida and Ley de Punto Final) of 1985–1986 stopped the trials until 2003, when the Congress repealed them, and in 2005 the Argentine Supreme Court ruled they were unconstitutional.
