Who is answerable for "maximum work hours of a doctor in India"

I had raised a RTI to MOHFW asking 1) maximum permissible work hours per week for a doctor in India 2) Maximum permissible work hours at a stretch ( in a single shift ) in an emergency ward , for a doctor employed within India 3) will the employer / hospital authority held legally responsible for "making / scheduling a doctor employee to work more than the maximum upper limit of work hours in a single shift / week" MOHFW rejected my RTI stating "health being a STATE matter I should approach individual states in India for the answer". My question is "on behalf of a working / employed doctor in a govt / private hospital within India . My question is not on behalf of a junior resident doctor undergoing a post grad course in govt hospitals of India. Whom should I approach now , if I want to know the maximum permissible working hours for a doctor employed in West Bengal , India. Shall I approach West Bengal university of health sciences? Will they be answerable for an "non academic employed doctor " ? Kindly guide .
