new Institute in the sense that it had no relation with the erstwhile NCDM. It, therefore, requires consideration by NIDM whether the services of the Petitioner prior to creation of NIDM can be counted for the purpose of regularisation and other benefits such as pension etc. and whether by virtue of his appointment on 01.01.1999 with NCDM, he can be compelled to opt for the NPS and not be a member of the OPS.
