One reason Wajahat saab said so is his experience while dealing Subhas Bose death related cases that my friends and I are contesting before the commission. The following is taken from the decision of the commission (full bench):
Earlier, a public authority could bar any information from disclosure under the Official Secrets Act, simply by classifying the information as secret or top-secret. That option has been effectively excluded by the RTI Act. Any decision to withhold information from public access is to be justified rationally, under the provisions of the Act. The decision to bar an information from disclosure can no more be arbitrary. It will need to pass the Commission's scrutiny.
