52 combat impunity, which has been defined as “the total lack of investigation, capture, prosecution, trial and conviction of those responsible for violations of the rights protected by the American Convention.”72 124. Consequently, the State has the obligation to investigate the facts that gave rise to the violations confirmed in this judgment, and must order a real and effective investigation in order to identify and punish those responsible for the violations. * * * 125. Concerning the reimbursement of costs and expenses, this Court must evaluate their scope with prudence; they includes the expenses for the steps taken by the victims before the authorities in the domestic jurisdiction and also those that arose in the course of the proceeding before the inter-American system. This evaluation may be made based on the principle of fairness and taking into account the expenses indicated by the parties, provided that the quantum is reasonable73. 126. To this end, the Court considers that, in reimbursement of the costs and expenses generated in the internal and the international jurisdictions, it is fair to grant the victims the following amounts: Manuel Aguirre Roca, US$25,000.00 (twenty-five thousand United States dollars) or the equivalent in Peruvian money when the payment is made; Guillermo Rey Terry, US$25,000.00 (twenty-five thousand United States dollars) or the equivalent in Peruvian money when the payment is made; and Delia Revoredo Marsano, US$35,000.00 (twenty-five thousand United States dollars) or the equivalent in Peruvian money when the payment is made. 127. With regard to the items established in paragraph 126, these should be agreed on and paid as soon as possible, in accordance with the applicable Peruvian law. 128. In order to comply with this judgment, the State must pay the compensations established in favor of Manuel Aguirre Roca, Guillermo Rey Terry and Delia Revoredo Marsano, within six months of notification. When it disburses the compensations granted in this judgment, the State must pay the amounts in relation to the actual value of the salaries that they failed to receive over the corresponding period (salaries in arrears). Finally, if, for any reason, it is not possible for the beneficiaries to receive the compensations within the indicated six-month period, the State must deposit the said amounts in an account or deposit certificate in a solvent financial institution under the most favorable conditions. If, after ten years, the compensation has not been claimed, the amount will be returned to the State of Peru, with the interest earned. 129. In accordance with its consistent practice, this Court reserves the authority to supervise complete compliance with this judgment. The proceeding will be closed once the State has fully complied with the provisions of the judgment. 72 Cf. Bámaca Velásquez case, supra note 4, para. 211. 73 Cf.
