completion of 15 years of service from the date of his initial appointment, i.e., 02.07.1982 under the provisions of Orissa Revised Scale of Pay Rules 1998. It is further contended that while passing the order impugned, the authority has not applied its mind to the extent mentioned above and mechanically rejected the claim of the petitioner. It is contended that though the petitioner, prior to filing of the present writ petition, had approached this Court by filing W.P.(C) No.4915 of 2011, but the same was withdrawn on 19.01.2012 to file better application. Consequentially, the present application has been filed where emphasis has been laid on the words “post” or “grade” in the scale of pay, which an employee had been drawing. It is further contended that the scale of pay may undergo changes during the tenure of service of an employee following revision of pay scale from time to time or the employee’s acquiring higher qualification. As per the finance department office memorandum, an employee who has held the same “post” or “grade” for 15 years is to be considered for advancement scale of pay. Therefore, nonconsideration of the same is arbitrary, unreasonable and contrary to the provisions of law.
