PIO is not furnishing information inspite First Appellate AUthority.

[vijaypandeyllb 1]

The PIO is not providing information and after order of the FAA he is not providing the information. The FAA is not taking any action and stating that he not no power to complel ?

What can be done?

[Prasad GLN 1,806]

Going for second appeal is the only option, and such non obeyance of FAA orders are being taken as serious by all ICs, as they are reduced to subordinate action of directing PIO to provide the information as per FAA orders.  Pray for penalty, recommendation for disciplinary action in your second appeal and mark this as copy to PIO.  It may work  if PIO is sensible.
