“11. In view of the factual position noticed hereinabove, the reason indicated by the Appellants in declining the claim of the Respondent Sat Pal for appointment out of the waiting list is clearly unjustified. A waiting list would start to operate only after the posts for which the recruitment is conducted, have been completed. A waiting list would commence to operate, when offers of appointment have been issued to those emerging on the top of the merit list.

If Trilok Nath was found eligible for appointment against the vacancy in question out of the same waiting list, the Respondent
