22 November 1992 to January 1993, payment of which has not been accredited before this Court. According to a document dated March 19, 1999, BHP Tintaya S.A. stated that the amount paid constituted “a provisional payment, in compliance with the Supreme Court judgment of February 2, 1993 […]. The final amount of the pension [would] be determined by the Actuarial Calculation Office of the ONP. The company [would] transfer to the [ONP] the corresponding funds for the pension payments from April of this year.”90 Based on the evidence provided by the parties, this did not occur. The total amount paid to Mr. Muelle Flores for provisional payment of the pensions owed is S/97,600.00 soles. 81. On October 26, 2000, the ONP replied that “it [was] only competent to decide on claims for the payment of pensions of those institutions whose administration and pension payments [had] been transferred to it […] by express legal provisions, a situation that had not occurred in the case of [Mr. Muelle’s] institution [referring to the company]”, and advised him to file his claim with the company paying his pension.91 82. In November 2004, the ONP sent a new communication to Mr. Muelle Flores in response to his notarized letter,92 stating that his name “[did] not appear in [its] document processing system of Decree Law N° 20530, […] [and that] [through a resolution of January 2004] the Pension Standardization Office -ONP, ha[d] been delegated the task of recognition, declaration, qualification and payment of pensions of those entities privatized, liquidated, deactivated and/or dissolved under Decree Law N° 20530 that [had] their own respective financial resources, and that BHP Tintaya S.A. company [did] not appear to be included among those under the responsibility of the ONP.”93 83. Mr. Muelle Flores sent a notarized letter to the Ministry of Economy and Finance (hereinafter the “MEF”), requesting information as to whether Law No. 28115 - establishing that the MEF was the State entity responsible for paying the pensions of workers following the privatization of state companies (infra para. 102) - was applicable to him. Mr. Muelle Flores also requested information as to whether after the privatization of Empresa Minera Especial Tintaya S.A., the mandates issued in the Supreme Court judgments of February 2, 1993, and October 29, 1997, as well as the Constitutional Court judgment of December 10, 1999, were assumed as an obligation by said Ministry. In response, Mr. Muelle Flores was informed that “the Ministry of Economy and Finance ha[d] not assumed the obligations in relation to [his] pension […] given that a judgment by the Constitutional Court expressly required the Empresa Minera Especial Tintaya S.A. to continue paying his pension, and therefore Law No. 28115 [was] not applicable to his specific case.”94 to December, 1999; e) February 18, 2000, for the sum of 2,400 soles for pensions corresponding to the months from January to March, 2000; f) May 11, 2000, for the sum of 2,400 soles for pensions corresponding to the months from April to June of 2000; g) September 22, 2000, for the sum of 4,800 soles for pensions corresponding to the months from July to December 2000, and h) 4,800 soles for pensions corresponding to the months from January to June to December, 2001.
