If Rule 13(1) is interpreted in this manner, no disharmony will result in the consequences of applying all the adhoc rules We think that only by construing Rule 13(1) in this manner the Government framed the seniority list of 1974 soon after framing the Adhoc Rules, 1973 by according seniority to the first and second class Post Graduate Junior Lecturers over the third class Post Graduate Junior Lecturers who were senior to them when all of them were working as Post Graduate School Assistants before they were appointed as Junior Lecturers, As stated earlier, before the Tribunal it was argued for the private respondents 3 to 8 in Representation Petition 595 of 1977 that the prayer for quashing Rule 13 (1) of the Adhoc Rules has to be negatived in view of the High Court 's judgments in Writ Petition 4358 of 1974 and Writ Appeals 920 and 938 of 1975 and that it is not the contention of the petitioners in that petition that the impugned revised seniority list of 1976 is contrary to the directions given in those judgments.
