Criminal Investigation (Covert Powers) Act 2012

This section applies if the chief officer of a law enforcement agency gives a witness identity protection certificate for an operative of the agency in relation to a proceeding.

The chief officer may cancel the witness identity protection certificate if the chief officer considers that it is no longer necessary or appropriate to prevent the disclosure of the operative’s true identity or where the operative lives.

If the chief officer cancels the certificate —

after it has been filed in a court and before the matter has been finalised by the court, the chief officer must immediately give written notice to the court and each party to the proceeding that the certificate has been cancelled; or

after it has been given to the Clerk of a House of Parliament and before the matter has been finalised by the parliamentary committee concerned, the chief officer must immediately give written notice to the Clerk that the certificate has been cancelled.
