Criminal Investigation (Covert Operations) Act 2009

If, in relation to proceedings, the chief officer of a law enforcement agency considers that it is no longer necessary or appropriate to prevent the disclosure of the identity of a local operative or where he or she lives, the chief officer may cancel a witness identity protection certificate in respect of the local operative.

If a witness identity protection certificate is cancelled after it has been filed in court under section 37, the chief officer must immediately give written notice to the court and each party to the proceedings that the certificate has been cancelled.
