379. As the Court has indicated on previous occasions, costs and expenses are included in the concept of reparation established in Article 63(1) of the American Convention.443 380. In their briefs with pleadings and motions and with final arguments, the representatives asked the Court to order the State to pay the following amounts for costs and expenses: (a) the sum that the Court establishes, in equity, to the Barrios family for their disbursements in the domestic legal proceedings; (b) to the Aragua Commission, US$30,000.00 (thirty thousand United States dollars) for the expenses incurred at the domestic level and in the international sphere up until the presentation of the pleadings and motions brief, and US$2,599.00 (two thousand five hundred and ninety-nine United States dollars) for the expenses incurred subsequently; (c) to COFAVIC, US$7,078.00 (seven thousand and seventy-eight United States dollars) from October 2010 until the presentation of the pleadings and motions brief, and US$8,990.00 (eight thousand nine hundred and ninety United States dollars) for the expenses incurred subsequently, and (d) to CEJIL, US$17,000.00 (seventeen thousand United States dollars) from 2005 until the presentation of the pleadings and motions brief, and US$7,585.00 (seven thousand five hundred and eighty-five United States dollars) for the expenses incurred subsequently. 381. Regarding their reimbursement, the Court must assess their scope prudently, which includes the expenditure arising before the authorities of the domestic jurisdiction and that incurred during the proceedings before the inter-American system, taking into account the authentication of the expenses incurred, the circumstances of the specific case, and the nature of the international jurisdiction for the protection of human rights. The calculation may be made based on the equity principle and assessing the expenses authenticated by the parties, provided the amount is reasonable.444 382. The Court has indicated repeatedly that “the claims of the victims or their representatives for costs and expenses, and the evidence supporting them, must be presented to the Court on the first procedural occasion granted them, that is in the pleadings and motions brief, without prejudice to those claims being updated at a later date, to take into account the new costs and expenses that have been incurred in the proceedings before this Court.445 In the instant case, the Court observes that the documents forwarded by the representatives regarding the costs and expenses incurred prior to the submission of the pleadings and motions brief were presented late (supra para. 17). Consequently, the Court will only consider those provided with the final written arguments that refer to the new costs and expenses incurred owing to the proceedings before this Court; in other words, those incurred after the pleadings and motions brief. 383. Notwithstanding the foregoing, the Court has verified that the representatives incurred different expenses before the Court. Bearing this in mind, the Court determines, in equity, that the State must deliver the sum of US$2,000.00 (two thousand United States dollars), or the equivalent in Bolivares Fuertes, to Eloisa Barrios, and a total of US$18,000.00 (eighteen thousand United States dollars) to the Justice and Peace Commission of Aragua state, COFAVIC and the Center for Justice and International Law for costs and expenses.
