The Inquiry has secured strong legal protection for whistleblowers. Following a process of discussion with the offices of the Attorney-General and the Director of Public Prosecutions, the Attorney-General gave an undertaking on 15 June 2015 that no document or evidence provided to the Inquiry will result in, or be used in, any prosecution under the Official Secrets Acts or any prosecution for unlawful possession of the evidence in question.
This undertaking provides the greatest possible protection for whistleblowers, consistent with the requirements of the public interest.
