Salvador.425 The framework for this process was established in the Geneva Accord of April 4, 1990, following which the parties drew up a general agenda and a timetable for the negotiation process that were accorded in Caracas, Venezuela, on May 21, 1990.426 269. On July 26, 1990, in San José, Costa Rica, the parties signed the first agreement in the negotiation process relating to absolute respect for human rights,427 in which they agreed that “[a]ll necessary actions and measures shall be taken immediately to avoid any type of acts or practices that violate the life, integrity, safety and liberty of the individual, [as well as] to eliminate any practice of disappearances and kidnappings. Priority shall be given to the investigation of any cases of this nature that might occur, as well as to the identification and punishment of those found guilty.”428 This agreement was also the basis for the creation of the United Nations Observer Mission in El Salvador (ONUSAL), by Security Council resolution 693 of 20 May 1991, which was installed on July 26, 1991, in order to verify the political agreements reached by the parties to the internal conflict.429 270. The Mexico agreements of April 27, 1991, proposed constitutional reforms for the Armed Forces in relation to the judicial system and human rights, as well as regarding the electoral system. In addition, in these agreements the parties established the Truth Commission for El Salvador,430 with the mandate to investigate “grave acts of violence that had occurred since 1980, whose impact on society demands, with the utmost urgency, that the public may know the truth,”431 and to prepare a final report with its conclusions and recommendations of a legal, political or administrative nature, which could concern specific cases or be of a more general nature. The parties undertook to comply with the Truth Commission’s recommendations.432 271. Subsequently, “the Nueva York agreement opened the way to obtaining the final peace,”433 the negotiations culminating during the evening of December 31, 1991, with the signature of the Act of New York in which the parties acknowledged that they had reached agreement on all pending aspects and undertook to establish a cease to the armed confrontation. 272. The final peace agreement that ended the 12-year armed conflict was signed on January 16, 1992, at Chapultepec Castle in Mexico City, D.F. The El Salvador Peace Accord reaffirmed the need to overcome impunity, by establishing that: The parties recognize the need to the part of officers of the Armed rights is jeopardized.
