12 In view of the above, this Court does not find any infirmity in the seniority list, as alleged by the petitioner, warranting interference. The persons against whom the petitioner has grievance, were far senior to him, as they joined prior to his date of joining in the post of Foreman Grade I. The petitioner's grievance that, had the seniority list been prepared for Switch Board Operators in the year 1969, then, he would have been much above, is indeed far fetched, inasmuch as the petitioner accepted his subsequent promotions to the post of Commercial Inspector and Foreman Grade I and only when the seniority list of Foreman Grade I was prepared, he sought to challenge the same. The explanation offered by the Board that while preparing the seniority list of Foreman Grade I, the Board had taken into consideration, the date of initial appointment of persons from the erstwile R.W.E. categories and accordingly, the seniority list was prepared, is acceptable.
