16. It is also relevant to refer to the instruction circulated by the Railway authorities in the letter dated 29/07/1997 providing guidelines for relieving the promotees to the next post. The instruction stipulates that whenever the employees are not relieve within 3(three) months of the issue of the promotion orders such cases must be put up to the DRM or the Head of the Office and the controlling officer held responsible for not relieving the staff concerned. The learned counsel for the petitioner submits that in terms of the instruction issued by the Railway authorities, the controlling officer of the respondent i.e. Area Manager (AM), Badarpur, N.F Railway keeping the interest of the respondent brought the matter to the notice of the Addl. Divisional Railway Manager (ADRM), Lumding who thereafter wrote the letter dated 24/04/2006 to the General Manager (P), Maligaon agreeing to the proposal for temporary variation of the post of P.S-II from Lumding to AM, Badarpur for a period of 6(six) months, consequent to which the General Manager (P), Maligaon, N.F Railway issued the memorandum dated 29/05/2006 variating one post of P.S-II from ADRM, Lumding to AM, Badarpur for 3(three) months w.e.f. 01/06/2006 to 31/08/2006 and allowed the respondent to join the variated post of P.S-II at AM, Badarpur w.e.f. 01/06/2006. The learned counsel for the petitioner submits that all these steps were taken by the authorities to enable the respondent to avail the benefits in the promotional post and only because some delay has been occasioned that by itself cannot be a ground to grant retrospective promotional benefits to the respondent from 13/12/2005 and/or from 01/01/2006. This Court is inclined to accept the submission of the learned counsel for the petitioner that some delay in carrying out the instruction of relieving the promotee by itself will not confer a right to the respondent to claim the promotional benefits from a retrospective date as the respondent had never worked in the post during that relevant point of time. A reading of the letter dated 29/07/1997 containing the instruction nowhere speaks of extending the promotional benefits from a retrospective date in the event delay is occasioned in carrying out the instruction nor it is the case of the respondent that the instructions were flouted while relieving the respondent in
