However, the 3rd and 4th respondents have not taken any steps to fill up the vacancy of the Principal by promoting a suitable candidate from among the senior most among the heads of the Departments for all these years. As per the guidelines of the Department of Technical Education, any candidate can hold the post as in-charge only for a period of five months and within the said period, the educational institution shall post a suitable candidate as per the seniority among the heads of the department. The present Principal-in-charge, namely, S.Mohan, on account of his illness, availed frequent leave on medical grounds. During his leave period, the administrative work of the 4th respondent should not be affected and to avoid such dislocation, the Chairman of the 3rd respondent Trust and the Chairman of the Governing of Council, the 4th respondent, by an order dated 25.03.2015, appointed the petitioner as Principalin-charge during the absence of Mr.S.Mohan. According to him, he was forcibly removed by the Secretary of the P.T.Lee Chengalvaraya Naicker Polytechnic College, by order dated 20.06.2015. The said order was sought to be enforced forcibly on 06.07.2015 to stop the intervention of the office bearers of the Staff Association. Thereafter, P.T.Lee Chengalvaraya Naicker Polytechnic College Staff Association submitted a representation to the Commissioner of Directorate of Technical Education. The 6th respondent, namely, R.Balasubramanian, who is 13 years junior to the petitioner and working as the Senior Lecturer of Civil Department was appointed as Principal-incharge, which is in gross violation of the guidelines in Chapter III Cl. (13) of DOTE and it is also in violation of principals of natural justice. The proceedings of the third respondent dated 20.06.2015 cannot supersede the earlier order dated 25.03.2015 passed by the Chairman of Governing Council appointing the petitioner as Principal-in-charge of the 4th respondent Polytechnic in accordance with the Guidelines issued by the Directorate of Technical Education. It is this order dated 20.06.2015 which is now under challenge in W.P.No.21517 of 2015.
