8.Coming to the legal submission, no doubt according to the G.O as well as the condition of service under Section 63 of Tamil Nadu Government Servants (Conditions of Service) Act, 2016, different age limit was given to the Ex-service man while competing for public employment. According to the Section 63 of the Tamil Nadu Government Servants (Conditions of Service) Act, 2016, the maximum age limit for Ex-serviceman under General category is 50 years and for others is 55 years. But there is no mandatory requirement on the part of the authorities to follow the age limit prescribed under the Tamil Nadu Government Servants (Conditions of Service) Act, 2016. Though such age limit has to be followed by the authorities generally for a special reason or in view of any peculiar recruitment, they have got right to fix the different set of age criteria, which is being protected under Section 68 of the Tamil Nadu Government Servants (Conditions of Service) Act, 2016, wherein it has been specifically mentioned that, if there is a contravention between the Special Rule and the Act 2016, the Special Rule will prevail.
