“10. I may also note that there is no delay and laches in filing this petition because once the recommendations of DPC became final, and documents were issued in the office of respondent no.3 itself to this effect, and filed at running pages 286-287 showing that petitioner was in fact promoted as an Assistant Engineer w.e.f 1.7.1983, I would not like to hold the petition as barred by delay and laches unless there was a specific refusal issued to the petitioner denying the benefits of the post of Assistant Engineer, and only when cause of action would have accrued to the petitioner to approach the Court. In the absence of any refusal addressed to the petitioner, that he would not be promoted to the post of Assistant Engineer in spite of his being put on the merit list panel as per the DPC of February, 1984, there was no need of the petitioner to approach the Court, albeit the petitioner will only be entitled to monetary emoluments for the promoted post for a period not more than three years prior to filing of the present writ petition.
