However, M.C. may sanction such leave in special circumstances.
Pls refer to the relevant G.O.!
For the rest of reply I fully agree! Permission to pass graduate teachers for enhancement of qualifications is barred by para 4 of G.O. 593 SE dtd 27.11.2007. So, there is no question of grant of study leave.
Anyway, I personally think that the para 4 of the G.O. is unjustified and, encroaches on human rights!
