“12.Contention by the appellants that the returned proposals were not challenged by the management and hence it has to be treated as accepted and hence the teachers have no right to question the same cannot be accepted. It has to be seen that ultimately, it is the teachers who are affected. Therefore, even if the management has not taken up the cause, the aggrieved teacher has every reason to question the returned proposals. The educational authorities ought to have considered that the very object of the Tamil Nadu Recognised Private Schools (Regulation) Act, 1973 and the Rules made thereunder are to protect the interests of the teachers and students. Therefore, right of the teacher cannot be said to be extinguished. Power of the educational authorities to issue directions to fill-up the posts on conversion cannot be questioned. At the same time, the schools should be given latitude to fill-up the required posts. If Maths and other subject teachers are already working in a school, the management should have the right to fill up the posts with other subjects, if there is a need for filling up the posts with the required subjects. ”
