as their service conditions are governed by different rules, but, it appears that the learned counsel for the State has made the submission, which is not relevant in this case. The petitioner has not asked for any treatment at part with the teachers of the constituent colleges and universities. The Science & Technology Department, Bihar, Patna, in pursuance of the order passed in C.W.J.C. No. 7169 of 1991 held that the Foreman and senior/junior instructors are also teaching staff working in the engineering colleges and the different polytechnics of the Government of Bihar and, accordingly, they were granted pay scale.
