The judicial process for the first three military Juntas, as mandated by Executive Order No.158/83, was to be carried out by the Supreme Council of the Armed Forces (Consejo Supremo de las Fuerzas Armadas, CONSUFA) in accordance with the provisions of the Code of Military Justice. In February 1984, the National Congress amended this Code (Act No. 23,049) to include specific guidelines for trial proceedings concerning the crimes committed by the military personnel from the Armed Forces, as well as the security, police, and penitentiary forces under their operational control and who had been in active service during the period going from March 24, 1976, through September 26, 1983. A deadline was imposed on the military justice system that, if not met, would allow for the intervention of the civilian justice system. This is what eventually happened. As a result, civilian courts were assigned sentencing reviews, and victims were allowed to participate in the proceedings. Besides, it was established that a defense of due obedience could not be invoked in the face of “atrocious and aberrant acts.”
