The second preliminary objection was also overruled on the grounds: (a) that the petitioners had not prayed for the quashing of the entire orders but they were aggrieved only with that portion of the orders by which the contesting respondents were appointed retrospectively from the date of the publication of the results of diploma in mechanical/electrical engineering examination, which affected the seniority of the petitioners in the revised gradation list:(b) that the petitioners came to know of the two orders after the preparation of the revised gradation list on 17th November, 1973 wherein the contesting respondents were placed above the petitioners; (c) that the Court was mainly concerned with the revised gradation list, but with a view to find out the basis for preparation of the revised gradation list, the Court had to examine as to whether the retrospective appointment of the contesting respondents by the aforesaid two orders in the circumstances was valid.
