Under Item 30, the sentence in the Trial of the Juntas provided for the investigation of the highest-ranking officials across zone and subzone commands. It also called for the inquiry of those accountable for operations. The judicial investigation of State-sponsored terrorism in the province of Córdoba was initiated in February 1984, following a complaint filed by the Service Peace and Justice (Servicio Paz y Justicia, SERPAJ). Additional lawsuits joined this initial complaint over time. The Supreme Council of the Armed Forces failed to meet the deadlines imposed by Act No. 23,049. Accordingly, there was no further progress in the case. Later on, the Court of Appeals of Córdoba undertook the investigation, gathered all the complaints, and consolidated them into case 31-M-87, which later became known as the “Master Case” or the “Menéndez case”. Significant portions of this investigation were halted by the Due Obedience Act, passed a few months later. However, they were resumed in 2005. In the case of Menéndez, who was not covered by the due obedience principle as he was the one who gave the orders, the process was interrupted when President Carlos Menem pardoned him in 1989, prior to any trial.
