66 they have the authority to access pertinent documentation and information to investigate the facts denounced and to take the measures and make the inquiries promptly that are essential to elucidate what happened to the disappeared persons in this case; d) Since grave violations of human rights are at issue,284 and considering the continuing or permanent nature of forced disappearance, the effects of which persist until the fate or whereabouts of the victims and their identity have been determined (supra paras. 83 and 92), the State must abstain from resorting to mechanisms such as amnesty for the perpetrators, or any other similar provision, such as prescription, non-retroactivity of criminal law, res judicata, ne bis in idem, or any other similar exclusion of responsibility to avoid this obligation, and e) Guarantee that the investigations into the facts that constituted the forced disappearances in this case remain at all times in the ordinary jurisdiction. 186. Also, in the circumstances of the present case, the Court deems necessary that the State adopts other measures, such as: a) Establish coordination mechanisms between the different State bodies and institutions with the powers to investigate, and mechanisms to monitor the cases being processed for the forced disappearance of children during the armed conflict; to this end, a database on the matter must be set up and kept updated in order to ensure the most coherent and effective investigations; b) Elaborate protocols for procedures in this matter with an interdisciplinary approach and train the officials involved in the investigation of serious human rights violations so that they are able to use the available legal, technical and scientific elements; c) Promote pertinent actions of international cooperation with other States in order to facilitate the collection and exchange of information, as well as and other necessary legal actions, and d) Ensure that the different bodies of the justice system involved in the case have the human, financial, logistic, scientific and other resources necessary to perform their tasks adequately, independently and impartially, and adopt the necessary measures to guarantee that judicial, prosecutorial and investigative officials and other agents of justice have an adequate security and protection system, which takes into account the circumstances of the cases for which they are responsible and the place where they work, and allows them to perform their functions with due diligence, and to protect witnesses, victims and next of kin. 187. The State must ensure the full access and capacity to act of the victims or their next of kin at all stages of the investigation and trial of those responsible.285 In addition, the results of the corresponding proceedings must be made public so that Salvadoran society 284 Cf.
