Mahesh Grover, J. —By this order we will dispose of C.W.P. Nos.2625 of 2012, 13566 of 2011, 19841 of 2013, 2564 and 18941 of 2016.

2. For the sake of convenience, brief facts have been taken from C.W.P. No.2625 of 2012.

3. The writ petitions have been filed questioning some of the provisions of the Haryana Civil Service of Engineers, Group A, Public Health Engineering Department Act, 2009 (herein after referred to as the Act) in particular, 3rd proviso to Section 9 and the impact of the rules on inter-se seniority and prospects of promotion.

4. As far as the individual grievances are concerned, they flow from the action of the respondents by applying the rules to determine their seniority and adversely affect their chances of promotion with reversion as a consequence in some of the cases.

5. Since the principal challenge is to the provisions of the Act, it would be essential to determine this issue in the first instance before commenting on the Act of the State and its impact on the petitioners' claim for seniority and promotion. An identical challenge has been mounted
