Is seniority affected by a different joining date?

I filed a WRIT petition in the honourable Allahabad High Court against the biased recomputation of the DPC. The subject DPC committee member had violated several DOPT guidelines and wrongly interpreted its promotion policy because earlier I pointed out a blunder in the work of One of the members of the DPC. My WRIT is pending to decide meanwhile I have been got promoted in subsequent DPC. Can I use the subject WRIT for the reckoning of my seniority from the disputed DPC?
