Government sources said the new rules seek to remove any ambiguity in interpretation of orders issued earlier regarding Fundamental Rule 56(j)/l and Rule 48 of the CCS (Pension) Rules, 1972, which provide for review of performance of a government servant after attaining 50/55 years of age or on completion of 30 years of qualifying service, with a view to ascertain if he should be retained in service or retired in public interest. The officer added that the latest DoPT office memorandum on premature retirement was not different from the procedures and practices already being followed, but only sought to consolidate the guidelines and instructions issued from time to time on the subject, in one single place, apart from offering better clarity to the existing instructions to enable uniform implementation.
