investigations and to hold the respective oral trials. In addition, the petitioners and their legal representatives have also appealed to the highest authorities of the Attorney General's Office in order to request that the prosecutors involved in the cover-up processes play a more proactive role when prosecuting criminal public actions272. 290. Along the same lines, the Commission emphasizes that the procedural object of the investigations outlined in this section is the prosecution and possible imposition of criminal penalties for acts of concealment and cover-up of the truth by public officials. The importance of investigating and prosecuting these types of acts within a reasonable time is particularly high given that the cover-up maneuvers took place within the framework of the investigation into the terrorist attack on the AMIA headquarters, which resulted in dozens of fatalities and hundreds of wounded and was classified by the national judicial authorities themselves as a case of serious human rights violations. 291. Finally, in relation to the investigation of the complaint filed in January 2015 by prosecutor Nisman for the possible crime of cover-up in the context of the signing of the Memorandum of Understanding between Argentina and Iran, the Commission has verified that, 5 years after the initiation of the judicial investigation, the Argentine judicial authorities have not yet issued a judgment that establishes the existence or not of criminal conduct on the part of the people subjected to the process, neither there is a judicial pronouncement that determines that the facts denounced actually occurred. iii) Conclusion 292. In light of the above considerations, the Commission concludes that the period of more than 20 years that the various criminal proceedings in which the facts covering up the attack on the AMIA have been investigated have not resulted in an effective determination of the corresponding responsibilities. In this sense, the processes for the cover-up have not contributed to clearly identify the actions or omissions in which the authorities incurred, which is especially serious in the present case where, as has been established, there are multiple irregularities and deviations that have become factors of impunity. 293. Consequently, these processes have been extended in an unreasonable manner, they have not contributed to the knowledge of the truth about the cover-up maneuvers and, therefore, they have not corrected the multiple irregularities that have been committed throughout the investigation. In particular, the Commission observes that such investigations have not revealed what were the real motivations that could be found behind the facts under investigation, including the generation of evidence to produce a conviction on the involvement of certain Buenos Aires police officers in the events and in the abandonment of the so-called “Syrian / Kannore Edul lead”. 294. In view of the foregoing, the Commission concludes that the various processes into the cover-up the attack on the AMIA have not been conducted diligently and within a reasonable time. Consequently, the Commission understands that there has not been an effective remedy that meets the requirements set forth by Articles 8 and 25 of the American Convention. 1. Regarding the reasonable time and the right to the truth 295. Considering the elements for the analysis of the reasonable time set out above, the Commission acknowledges that the investigation followed by the facts of this case is somewhat complex, taking into account the nature of the facts and that the criminal structure or network that could be behind the attack could even go beyond the borders of the Argentine State. 296. Notwithstanding this, as has been stated throughout this report, the conduct of the authorities in charge of the investigation -especially in the initial proceedings and those in charge of the Federal Criminal and Annex 19.
