15 46. The Decree Law No. 20530 pension scheme regulated “State pensions and benefits for civil services rendered by workers of the national public sector” who were not included in the National Pensions System established by Decree Law N°1999040 of 1973. Under that scheme, created to “compensate state workers who could not join the National Pensions System,”41 workers acquired the right to a pension upon completing 15 years of service to the State, in the case of men, and 12.5 years in the case of women.42 The pension was calculated “on the basis of the last twelve (12) salaries earned and at a ratio of 1/30 per year of service for men and 1/25 per year of service for women.”43 47. With the promulgation of the Constitution of 1979, after the issue of Decree Law No. 20530, the Eighth General and Transitory Provision established the right of retired workers included in this pension scheme, and with more than 20 years of service to the State, to have their pensions progressively adjusted or equalized with the wages of active public officials and/or public servants.44 For this reason, Decree Law No. 20530 was known as the “Cédula viva” system or the “renewable pension,” due to the “mirror effect” that automatically equalized the pensions for dismissed or retired workers with the wages of active workers (active public servants), using as reference the last position held by the pensioner.45 In this sense, the pension received by the beneficiary was equal to that of the active worker, and therefore the readjustment was in line with increases in the latter’s wages (infra para. 48). 48. The benefit of pension equalization was a privilege extended by the Constitution to persons subject to Decree Law No. 20530, as it was not originally included in the text of said Decree. This benefit was implemented through Law No. 23495 of November 1982 and its Regulations, and through Supreme Decree No. 015-83-PCM of March 1983. Article 5 of that Law established that: “any postequalization increase awarded to active public servants in the same or a similar position to the last position held by the dismissed or retired worker shall give rise to the same pension increase to which the active public servant is entitled.”46 49. On September 30, 1990 Mr. Muelle Flores retired from Tintaya S.A., a State-owned company governed by private law. Mr. Muelle Flores received his pension in accordance with Decree Law No. 20530, from October 1, 1990 until January 1991. On February 27, 1991, he received Communication No. GA/0130/91 from the company’s administrative manager, unilaterally informing him that, on the advice of an external legal adviser, the pension scheme under Decree Law 20530 was being suspended.47 Mr. Muelle Flores was informed that the Decree was no longer applicable to company 40 Cf.
