since three other mining executives were promoted from E-6 grade to E-7 grade from 28th July, 2009. Such claim of the petitioners is based on the contentions that those three mining executives were borne in E-6 grade w.e.f. 30th September, 2003 whereas petitioners, four in number, were promoted from E-5 to E-6 grade, according to the petitioners, w.e.f. 20th July, 2003. Therefore, it has been claimed on behalf of the petitioners that in E-6 grade inter se seniority of these two groups four writ petitioners and those three mining executives unleashes the fact that petitioners are senior to those three mining executives which ought to have been relevant consideration at the time of promoting the mining executives from E-6 to E- 7 grade.
