the work [he] and [his] team had carried out before the inter-American system as well as other expenses incurred during the litigation.” 305. Regarding costs and expenses, the State indicated that “it would abide by what is proved before the […] Court.” 306. The Court reiterates that, in keeping with its case law,277 costs and expenses form part of the concept of reparation, provided that the measures taken by the victims in order to obtain justice, at both the national and the international level, entail expenditure that must be compensated when the State’s international responsibility is declared in a judgment. Regarding their reimbursement, the Court must prudently assess their scope, which includes the expenses generated before the authorities of the domestic jurisdiction, as well as those generated during the proceedings before this Court, taking into account the circumstances of the specific case and the nature of the international jurisdiction for the protection of human rights. This assessment can be made based on the principle of equity and taking into consideration the expenses indicated by the parties, provided their quantum is reasonable. 307. The Court has indicated that “the claims of the victims or their representatives regarding costs and expenses, and the supporting evidence, must be presented to the Court at the first procedural moment granted to them; that is, in the pleadings and motions brief, without prejudice to the said claims being updated at a later time, in accordance with the new costs and expenses incurred as a result of the proceedings before this Court.”278 In addition, the Court reiterates that it is not sufficient to merely submit probative documents; but rather, the parties must present arguments relating the evidence to the fact they consider it represents and, since this relates to alleged financial disbursements, must clearly establish the items and their justification.279 308. In the instant case, the Court has verified that the representative submitted vouchers for expenses in the amount of US$1,842.27 (one thousand eight hundred and forty two United States dollars and twenty-seven cents) corresponding to travel, accommodation and food in New York for three members of the International Human Rights Law Clinic of George Washington University in February 2011. 280 Consequently, the said expenses will be taken into account when determining the respective costs and expenses. In addition, as it has in other cases, the Court can infer that the representative incurred expenses in the processing of the case before the inter-American human rights system. 309. Therefore, the Court establishes, in equity, the sum of US$9,000 (nine thousand United States dollars) for costs and expenses in favor of Arturo J. Carrillo, the victims’ representative.
