142 vi. vii. viii. The OAS-sponsored process of dialogue with the self-defense groups; The operational results achieved by law enforcement bodies against the illegal self-defense units; and The results of the administrative proceedings. (c) As a result of the facts and violations acknowledged in the answer to the application, it was willing to submit a proposal for reparations negotiated with the petitioners who duly accredit their status. The Court’s findings 396. In this section the Court will determine measures of satisfaction that are not of a financial nature and that seek to repair the non-pecuniary damage, and will order measures of a public scope or repercussion.277 These measures have special relevance in this case owing to the extreme gravity of the facts and the collective nature of the damage caused. 397. The Court will not establish compensation for non-pecuniary damage in favor of the persons who were merely displaced from La Granja and El Aro and who are listed in Appendix IV of this judgment, because the Court considers it pertinent to grant reparations of a collective nature, which it will examine in this chapter. 398. As the State advised, the Special Committee for the promotion of investigations into violations of human rights and international humanitarian law has chosen this case for prompt attention to clarify the facts and punish those responsible (supra para. 395). The Court considers that this can contribute to compliance with these obligations. a) The State’s obligation to investigate the facts of the case, and to identify, prosecute and punish those responsible 399. The State must take the necessary measures to activate and complete effectively the investigations to establish the responsibility of all the authors of the massacre and the persons responsible by act or omission for failing to comply with the State’s obligation to guarantee the violated rights. The State must conduct criminal proceedings concerning the Ituango massacres, so that the facts are clarified and those responsible punished. The results of these proceedings must be published by the State, so that Colombian society may know the truth about the facts of this case. 400. To comply with the obligation to investigate and sanction those responsible in this case, Colombia must: (a) remove all the obstacles, de facto and de jure, that maintain impunity; (b) use all available means to expedite the investigation and judicial proceedings, and (c) grant guarantees of adequate safety to the victims, investigators, witnesses, human rights defenders, judicial employees, prosecutors 277 Cf.
