59 Considerations of the Court 157. To comply with the instant Judgment, the State must pay the compensations and reimbursement of legal costs and expenses within six months from the date it receives notice of the instant Judgment. 158. Pursuant to its case law,109 the State can fulfill its pecuniary obligations by payment in United States dollars or an equivalent amount in Argentinean currency, using for this calculation the exchange rate between both currencies in the New York Exchange, in the United States of America, the day before the payment. 159. Payment of the amount for pecuniary and non-pecuniary damages, as well as legal costs and expenses set forth in the instant Judgment, cannot be subject to currently existing taxes or levies or to any decreed in the future. In addition, if the State were to be in arrears, it must pay interest on the amount owed, according to the interest rate for arrearages in the Argentinean banking system. Finally, if for any reason it were not possible for the beneficiaries to collect the respective payments within twelve months, the State must deposit the respective amounts in the name of said beneficiaries in an account or certificate of deposit, at a solid financial institution, in United States dollars or their equivalent in Argentinean currency, under the most favorable conditions allowed by banking laws and practices. If after ten years the payment has not been claimed, the amount will return to the State together with the interest accrued. 160. With respect to the compensation ordered in favor of the children Tamara Florencia and Matías Emanuel Bulacio, the State must deposit the amounts in their name in an investment in a solid Argentinean banking institution, in United States dollars or their equivalent in Argentinean currency, within six months time, and under the most favorable financial conditions allowed by banking laws and practices while they are minors. If after five years from when said persons attain majority the compensation has not been claimed, the capital and interest earned will be distributed proportionally among the other beneficiaries of the reparations. 161. The Court reserves the authority to monitor integral compliance with the instant Judgment. The international proceedings will only be closed once the State has faithfully complied with the provisions of the instant decision. 109 Cf.
