[RTI INDIA] RTI Act - Government Circular

Dear Members,

I  have one question from the members regarding the Government Circular. 

What is a Government Circular? Who has the authority to issue Circulars OR what is the position (designation) of the particular official issuing the Circular? 

If I ask question through RTI Act to any Cooperative Society, does the Secretary of the Cooperative Society has right to issue a circular and deny any

information under Section 2H of the RTI Act?

Any information regarding this would be highly appreciated.

Thanks,

Shailmala
