Ext.P3 to the effect that pension will be limited to regular employees, who were in service as on 31.03.2013. They contend that since Ext.P1 policy decision had been taken as early as on 01.03.2011, the petitioners, who had retired from service after that date and before 31.03.2013, are also entitled to pension. It is contended that there exists absolutely no rationale for the fixing of the cut-off date of 31.03.2013 for the date of payment of pension. The petitioners relied on Exts.P6, P7, P8 and P10 Government Orders, to contend that in the case of similar pension schemes made applicable to other Government organizations, there was no cut-off date prescribed, and the pension schemes were made applicable from the date of the policy decision. It is further contended by the learned counsel for the petitioner that in the light of the binding decision of the Apex Court in D.S.Nakara and others v. Union of India [AIR 1983 SC 130], A.N.Sachdeva v. Maharshi Dayanand University [2015 (10) SCC 117] and Union of India and Another v. Sps Vains (Retd.) and Others [2008 KHC 4940]
