Thus, the appellants who were appointed to the guaranteed posts of temporary Assistant Engineers, as reserved for the top B students of Thomson College of Civil Engineering, Roorkee/University of Roorkee, constituted a class apart. One D.K. Laroiya who had been appointed as a temporary Assistant Engineer to one of the guaranteed posts in !945 and confirmed in the year 1949 made a representation dated April !5, !955 claiming seniority over all the Assistant Engineers appointed to guaranteed or non-guaranteed posts, irrespective of the order of appointment. While this represenc tation was pending, the State Government passed an order dated October 11, 1955 confirming the appellants i.e. holders of guaranteed posts w.e.f. April 1, 1955 in the permanent posts of Assistant Engineers, and later on by order dated July 20, 1956 determined their order of seniority. Subsequently, the Government by orders dated D November 7, 1956, April 9, 1957 and May 14, 1958 confirmed the temporary Assistant Engineers i.e. persons appointed to non-guaranteed posts as permanent Assistant Engineers, all w.e.f. April 1, 1956. By order dated May 29, 1961 the Government determined the seniority of respondents nos. l- le and 39 others referable to the date of their substantive appointment. On a combined reading of the impugned orders dated July 20, 1956 and the subsequent order dated E May 29, 1961, the appellants i.e. the ·directly recruited Engineer Students who had passed out from the Thomson College of Civil Engineering, RoorkeeiUniversity of Roorkee in order of merit i.e. to the guaranteed posts, were placed above respondents nos. 1- 12 and 39 others i.e. the temporary' Assistant Engineers. On the basis of their seniority and in view of their record of service, the appellants F had in the meanwhile been promoted as Offg. Executive Engineers in the years 1960 and 196 ! . Admittedly, respondents nos. !-12 who later on were promoted as Offg. Executive Engineers never filed any representation qua Executive Engineers and the seniority of the appellants as Executive Engineers remained unchallenged throughout G the period of !4 years.
