58 award her a grant covering all expenses and costs involved in such higher education, at the Peruvian public higher education center she may elect. f) Amendment to Article 320 of the Criminal Code 149. The State must adopt all measures necessary to amend, within a reasonable period of time, its criminal law in order to render it consistent with the international standards on forced disappearance of persons, paying special attention to the provisions of the American Convention and the Inter-American Convention on Forced Disappearance, pursuant to the criteria established in paragraphs 90 to 110 of the instant Judgment. D) Costs and Expenses 150. As the Court has stated on previous occasions,88 costs and fees are contemplated within the concept of reparations as enshrined in Article 63(1) of the American Convention, since the victim’s endeavor to obtain justice in the domestic as well as at international levels, and that of his successors or their representatives, lead to expenses and liabilities that must be compensated. With regard to their reimbursement, the Court must prudently assess their extent, which involves the expenses incurred when acting before the authorities within the domestic jurisdiction, as well as those incurred in the course of proceedings before the Inter-American system, taking into account the particular circumstances of the specific case and the nature of international jurisdiction for the protection of human rights. Such estimate may be made on the grounds of equitable principles and taking in consideration the expenses reported and proved by the parties, provided they be reasonable.89 151. As the Court has stated on previous occasions, the concept of costs encompasses those incurred in the legal proceedings before the domestic court system, as well as those pertaining to proceedings before international jurisdictional systems, such as the Commission and the Court.90 In the instant case, the representatives did not submit any evidence showing the amount of expenses they incurred during the proceedings both at national and international level, and requested the Court to determine, on an equitable basis, the amount of costs and expenses to be reimbursed. 152. For such purpose, the Court considers it proper to order the State to pay the sum of US $5,000.00 (five thousand United States dollars) or its equivalent in Peruvian currency, to Mrs. Victoria Margarita Palomino-Buitrón, for costs and expenses incurred both at the domestic and the international levels when acting before the Inter-American system for the protection of human rights. Mrs. PalominoBuitrón shall give her representatives the corresponding amount, depending on the assistance they provided her. 88 Cf.
