In the writ petition, the respondents-Corporation filed a counter affidavit contending that in the service register of the appellant, as per medical certificate No.05793, dated 29.5.1984, his date of birth was recorded as 29.6.1950 and that in the option-cum-nomination form of Staff benevolent-cum-Thrift (SBT), dated 9.5.1988, the appellant himself mentioned his date of birth as 1950. At no point of time, the appellant sought for alteration of his date of birth and therefore, he cannot seek such alteration after his retirement on medical grounds. It is the case of the respondents-Corporation that as per Regulation 19(1) of A.P.S.R.T.C. Employees (Service) Regulations, 1964 (for short ‘Regulations’), every person, on entering the service of the Corporation has to declare his date of birth which shall not differ from any declaration, express or implied, made by him for any public purpose before entering such service, and for this purpose, the date of birth as recorded in a school or college certificate shall be adopted without any modification. Regulation 19(2) also envisages that ‘where the person concerned is unable to furnish satisfactory evidence of his age, it should be assessed by a medical Officer of the corporation and the age so assessed or the age as declared by the person, whichever is mare, shall be accepted as final and the employee shall be assumed to have completed that age on the date of attestation by the Medical Officer.’ As per the said Regulations, basing on the medical certificate issued by the Civil Assistant Surgeon, APSRTC Hospital, Tarnaka, Hyderabad, dated 29.5.1984, the appellant’s date of birth was entered in his service record as 29.6.1950.
