What power does the vice-chancellor of BHU have over IIT BHU ?

Currently, the Vice-Chancellor of BHU has no power over IIT BHU as both are independent institutes. Although, they are united together under the name of Banaras Hindu University. The two institutes take their decisions independently. The Vice-Chancellor of BHU has no say over IIT BHU. But there was a small twist in all this. A few years back the Vice-Chancellor of BHU was also the Chairman of the Board of Governors of IIT BHU. Chairman of the Board of Governors is the most powerful person in IIT BHU. No decision can be taken without the permission of the Chairman. Since the same person was working at both these positions, the Vice-Chancellor of BHU was the most powerful person in IIT BHU but it’s not because he was the Vice-Chancellor of BHU, but because he was also the Chairman of Board of Governors of IIT BHU. But now things have changed as different persons are working in these positions. Mr. Rakesh Bhatnagar is currently the Vice-Chancellor of BHU and Prof. P. K. Jain is the Chairman of the Board of Governors of IIT BHU. Mr. Rakesh Bhatnagar does not have any power over IIT BHU.
