W.A(MD)No.367 of 2015 e) The validity of the G.O., came to be challenged by some of those who have completed the Certificate Programme in a batch of writ petition in W.P(MD)No.18237 of 2007. Vide his order dated 23.10.2007, the learned Single Judge of this Court upheld the legality of G.O.Ms.No.39 and proceeded to observe that the intent behind the G.O., is to prefer the Diploma Holders for the Post of Lab Technician Grade II and if there is any vacancy, that must be filled up with the One Year Certificate Holders. The Court has also noted that at the time of pronouncing its orders, there were 442 vacancies in the Post of Lab Technician Grade II, of which, 332 candidates have possessed their Two Year Diploma Programme and only 110 posts were remained vacant. The Court directed that the certificate holders in Lab Technician may be used to fill up in the rest of the vacancy. Subsequently, the Government came up with G.O.Ms.No.22 of the same Department, dated 29.01.2010. Vide this G.O., the Government directed maintaining of State-wise Seniority instead of District-Wise Seniority. This G.O.22 came to be challenged in the present writ petition.
