“… The earlier G.Os. were issued by the Government of A.P. without these legal entities amending its Rules/ Regulations/Byelaws, governing the age of superannuation and without the prior approval of the sole/majority shareholder i.e., the State Government as required under the Articles of Association/byelaws of these legal entities. As the Rules and Regulations, by which the petitioners are governed, stipulate 58 years as the age of retirement, these employees cannot claim any right to continue in service till they attain the age of 60 years. It is only if the request of these Companies/Corporations/ Societies, for amendment of its byelaws/rules and regulations, are approved by the State Government, and the rules/byelaws/regulations are amended thereafter in accordance with law, would their employees then be governed by the enhanced age of superannuation prescribed under the Rules/byelaws.
