Sir,
probably the mutual agreement between the c.g. and different state govt.s can be seen at DOPT website. the order is as following– DP&AR’s O.M.No.28/10/84-PU dated 29-8-1984. there has also an order on 1986 as following–No. 28(10)/84-P&PW.Vol.II 07/02/1986. Mr.donyi_polo kindly refer those. the 1986 order is also hosted at the same web-site.
thanking you.
