With due respects to the expert queries -as I understand from the RTI Act, there are only three steps in the RTI Act.
1.Application.to designated Public Information Officer,
2.The first appeal against PIO's action. to a superior authority with same public authority over PIO.with such designation as First Appellate Authority.
3.Second Appeal against PIO, with or without FAA order.
4.Finally writ before High Court.
There are two things involved in the query.
1)Whether society is a Public authority.
2. Who can contemplate action against PIO for not honoring IC decision which is another wise technically noncompliance of decision by higher authorities which amounts to a failure in duty and statutory obligation?
Again society is not always a public authority as per Supreme Court decision and the yardstick in such cases used by SC is that "An authority which ceases to exist without financial assistance by Govt" is a public authority.
2. Noncompliance of IC decision has to be dealt` only as per RTI Act like imposing the penalty of not more than 25,000/- Compensation for actual loss, recommendation for disciplinary action, all this against wilful, malafide and deliberate denial and any disobedience, after all, IC decision is to be treated as malafide dential. Under RTI only IC can take action as per his vested powers under RTI.
Coming to res judicata, since the main issue of providing information is not completed the process never comes under resjudicata.
RTI is just a road and never destination.
A society member has every right to inspect the records and make a complaint to Sub Registar and even report to police in all cases of misappropriation.
Such a Big response is not required, but I feel that unless I express my reasoning,my reply may be misinterpreted.
