If a citizen seeks information which is forbidden by other rules or Acts, what should a PIO do?

If the PIO decides to disclose information that relates to a Public Authority which it has treated as confidential, it can submit an appeal before the First Appellate Authority (FAA). The section 19(3) make it clear that the second appeal before CIC is against the decision passed by the FAA and it can be preferred by any of the aggrieved parties.
