NOC granting by state govt institute

Am faculty (assistant professor) in state govt. medical institute. My institute is not granting NOC to me for applying for job in other Institute for reason of deficiency of faculty in my department (according to norms of Medical council of India). This is story with other faculties in neary all depts. My dept is having shortage of faculty from 2 years. 2 recruiment advertisements were made (latest one was about1.5 years ago) but no candidate appeared, no efforts for recruitment & NOC been granted since then. institute is in rural area far from civilization, social advancement & personal settlement,without insentives, nearby city is 24 kms.Problems- 1.Few NOC been given with condition that relieving will be given when & if their dept. have sufficient faculty 2. Now Institute is making rule (through EC)that no NOC will be given for applying at lower/ similar post for 5 years and only 4 NOC canbe granted per year. - No efforts for recruitment being made -can these be challenged in court?
