474. Lastly, the principle of the complementarity of international law cannot be disregarded. This is recognized in the Preamble to the American Convention752 and has been taken into account by the Court in other cases753 to acknowledge the compensation granted at the domestic level and to abstain from ordering reparations in this regard, when this is pertinent. 475. The Court decides that the Colombian State must guarantee that all the persons who have been recognized as victims in this Judgment (supra paras. 431) have priority access to the said administrative reparations, and that it proceed to pay them, as soon as possible, irrespective of the time frames that domestic law may have established for this, avoiding obstacles of any type. The foregoing must be implemented within no more than one year of notification of this Judgment. 476. In addition, in the case of the next of kin of Marino López, the Court notes that they suffered different types of effects owing to his death, namely: (a) owing to the particularly cruel circumstances in which Marino López was executed (supra para. 435), and (b) owing to the fact that this act remained unpunished for 15 years, and that, even today, those responsible have not been tried or punished. Based on the criteria established in its consistent case law, the Court finds it pertinent to establish, in equity, for the pecuniary and non-pecuniary harm caused to Marino López Mena, the sum of US$70,000.00 (seventy thousand United States dollars) or the equivalent in Colombian pesos, which must be paid within the respective time frame (infra para. 482) to Mrs. Palacios, companion of Mr. López, as well as the sum of US$35,000.00 (thirty-five thousand United States dollars) or the equivalent in Colombian pesos, to each of Mr. López Mena’s children, and US$10,000.00 (ten thousand United States dollars) to each of his siblings, to be determined as indicated above (supra para. 435). E. Costs and expenses 477. The representatives indicated that they have been supporting the community from February 28, 1997, to date, as well as during “approximately eleven […] years of litigation at the domestic level, and four years at the international level.” They also indicated that the average expenditure, per person, to visit the humanitarian zones is US$700 (seven hundred United States dollars) and that, in activities of “gathering information, powers of attorney, development of the reparation proposal presented in this brief, and information activities to explain to the victims” about the inter-American system and the processing of this case, they had incurred expenses of US$17,500 (seventeen thousand five hundred United States dollars). Lastly, they calculated that their expenses in relation to the litigation before the Inter-American Court amounted to US$6,000 (six thousand United States dollars) and the value of the support provided from 2002 to 2011754 at US$793,866 (seven hundred and ninety-three thousand eight hundred and sixty-six United States dollars). To authenticate the foregoing, the representatives attached a series of invoices for public services, stationery expenses, restaurants, plane and bus tickets, payments they had made in the name of various individuals, and other elements, without providing any further explanation. 478. The Commission did not make any claims and the State did not refer to the representatives’ request. 752 Cf. Preamble to the 1969 American Convention on Human Rights: “Recognizing that the essential rights of man are not derived from one's being a national of a certain state, but are based upon attributes of the human personality, and that they therefore justify international protection in the form of a convention reinforcing or complementing the protection provided by the domestic law of the American States.” 753 Cf. Case of the Santo Domingo Massacre v. Colombia, para. 336, and Case of Manuel Cepeda Vargas v. Colombia, para. 246. 754 The total value of the support from 2002 to 2011 was disaggregated by the representatives as follows: (a) 49.5% personnel expenses; (b) 23.9% travel and transport expenses; (c) 3.7% legal procedures, and (d) 22.9% administrative expenses. 148
