analysis of specific conventional rights, would appear to provide some evidence for this. In the latter, as a principle derived from sources at the national level, it is able to ‘fill gaps’ when treaties and custom do not provide enough guidance.” 8 Juan E. Méndez, one of the leading legal experts on the right to the truth, has characterized it as an “An emerging—though rapidly developing—norm of international law.” 9 Likewise, he describes it as the “State obligation to reveal to the victims and society everything known about the facts and circumstances of massive and systematic human rights violations of the past, including the identity of the perpetrators and instigators” In this same sense, he argues that "This obligation presupposes the existence of massive or systematic human rights violations taking the form of the most abhorrent international criminal offences such as torture, genocide, disappearances, war crimes, or crimes against humanity” 10 He adds that “this obligation is likely to arise in contexts of Transitional Justice in Post-Conflict Situations marked by the end of political violence, the cessation of the hostilities, or the fall of the dictatorial regime; yet technically this obligation arises with the systematic human rights violation itself.” 11 Although some authors dispute its origin and legal nature, as evidenced in the above sections, in another line of thinking, the doctrine has established that "today, all the conditions and requirements are met to recognize the right to the truth as an autonomous fundamental right. All that is missing is formal and explicit recognition, both in international conventions and in States’ constitutions.” 12 Taken from: Yasmin Naqvi, “The right to the truth in international law: fact or fiction?” International Review of the Red Cross, June 2006, Original Version No. 862, pg. 28 Available at https://internationalreview.icrc.org/sites/default/files/irrc_862_2.pdf 9 Taken from: Juan E.
