Re: RTI
To the PIO first.
U can file RTI addressing the Head of Office, and it is the duty of Head of office to transfer the same to the designated PIO and inform you accordingly within 5 days.
If u are not satisfied with reply, then u can file to Appellate authority and the PIO must inform you the designation and correspondence address of the appellate authority if u demand to know in the same query. If the PIO does not divulge any information then it the duty of PIO to inform you the address of AO also.
