3.The said contention made in the counter is refuted by way of rejoinder by the writ petitioner. He has specifically contended that at the time of certificate verification, he has produced all the necessary certificates as prescribed in the notification of the respondent. As far as Higher Grade Test in Painting and Drawing conducted by Director of Government Examinations [Technical], Chennai, certificate for person studied in Tamil medium cannot be obtained from the Department of Government Examinations. Since the said examination is conducted by the Department of Government Examinations. For private candidates, obtaining certificate from the institution is also not possible since they directly apply for the examination and not through any recognised institution. When the candidates asked for PSTM certificate from Directorate of Government Examinations, it is also specifically informed by the Department of Government Examinations that the Department of Government Examinations is not conducting any course, but only conducting examination for Free Hand Outline and Model Drawing, they are not competent to say about the medium of instruction of the candidates who appeared for the examination and such certificate can be obtained only from the institute, where the candidate has undergone the training. This reasoning not factually applicable to the petitioner, since he has obtained PSTM certificate from the institute in which he has undergone the training and submitted the same during the course of certificate verification, but the said certificate has not been considered.
