I read the entire order of SC.
Basic facts of the case are about a short service commission AMC doctor who left Army and joined CRPF. He was Major at the time of discharge and had basic pay of Rs. 48000/- & grade pay of Rs. 6600/-. On employment in CRPF he was taken as Assistant Commandant with grade pay of Rs. 5400/- and placed at the beginning of Pay Band (PB3). Now the rule says that such re-employed person (SSC & EC only) should be given increments equal to number of years of military service. In his case these increments were given but it was less than Rs. 48000/- (last basic pay drawn).

This was challenged on the ground of "pay protection", which has been not agreed by SC.
For permanent commission officers the pay protection order is applicable in case of re-employment in civil.
