Re: In the absence of PIO how to initiate appeal procedure?
The Commissioner, Corporation of Chennai is the Appellate Authority under RTI Act. Please make an appeal to him before expiry of 60 days of your original RTI application. I haven't come across a format of appeal by TN govt. However you can make use of the format provided by our member hemasampat in her post no.2 in the following thread: https://www.rtiindia.org/forum/544-ap....html#post1821
Defeat is not final when you fall down. It is final when you refuse to get up.
