Article 22 Non-disclosure of damaging information
This rule applies where the Secretary of State certifies as “damaging information” any information, document or evidence which, in his opinion, would if disclosed to the person concerned or any other person be likely to:
adversely affect the health, welfare or safety of the person concerned or any other person;
result in the commission of an offence;
facilitate an escape from lawful custody or the doing of any act prejudicial to the safe keeping of persons in such custody;
impede the prevention or detection of offences or the apprehension or prosecution of suspected offenders;
be contrary to the interests of national security; or
otherwise cause substantial harm to the public interest;
and any such information, document or evidence is referred to in these Rules as “damaging information”.
The Commissioners shall not in any circumstances disclose to or serve on the person concerned, his representative or any witness appearing for him any damaging information and shall not allow the person concerned, his representative or any witness appearing for him to hear argument or the examination of evidence which relates to any damaging information.
Where the Secretary of State has certified information as damaging he shall within seven days of doing so serve on the person concerned and on the Commissioner, whether by way of inclusion with the application or response papers or otherwise, written notice of this stating, so far as he considers it possible to do so without causing damage of the kind referred to in paragraph (1), the gist of the information he has thus withheld and his reasons.
