105 241. The Court considers that the State should adopt immediately the necessary measures to adapt the detention conditions in the Yanamayo Prison to international standards and transfer any other prisoners who cannot be confined at the altitude of this prison owing to their health. In this regard, the State shall provide reports to this Court every six months on this adaptation, which shall be carried out within one year from notification of this judgment. * * * 242. With regard to expenses and costs, this Court must assess the amount prudently; they include those arising from the actions taken by the alleged victim’s representatives in the domestic proceedings and before the inter-American system for the protection of human rights. Taking into account that the representatives have not submitted vouchers, this assessment must be made on the basis of principles of fairness.282 243. To this end, the Court considers that it is fair to order the payment of US$30,000.00 (thirty thousand United States dollars), to be given to Mark and Rhoda Berenson, for costs and expenses in the domestic proceedings and in the proceedings before the inter-American system for the protection of human rights. * * * 244. The State shall comply with its obligations by payment in United States dollars or an equivalent amount in Peruvian currency, using the rate of exchange between the two currencies in force on the market in New York, United States of America, the day before payment, to make the respective calculation. 245. The payment for costs and expenses established in this judgment shall not be subject to any current or future tax or charge. The State shall comply with the measures of reparation and the reimbursement of expenses ordered (supra paras. 238, 239 and 243) within six months of notification of this judgment, except with regard to the Yanamayo Prison, where the measures should be complied with according to the provisions of paragraph 241 of this judgment. Should the State fall in arrears, it shall pay interest on the amount owed, corresponding to bank interest on arrears in Peru. 246. If, due to causes that can be attributed to the beneficiaries of the payment of costs and expenses, they are unable to receive this within the said period of six months, the State shall deposit such amount in their favor in an account or a deposit certificate in a reputable Peruvian banking institution, in United States dollars or the equivalent in Peruvian currency, in the most favorable conditions permitted by legislation and banking practice. If, after ten years, the compensation has not been claimed, the sum shall be returned to the State, with the interest earned. 247. According to its consistent practice, the Court reserves the right, inherent in its competence, to monitor full compliance with this judgment. The case shall be filed when the State has fully implemented all the provisions of this judgment. Within one 282 Cf.
