A Judge of the High Court may order that subsection (1) is not to apply if satisfied by a party to a civil or criminal proceeding that, having regard to the issues to be determined in that proceeding, the public interest in the disclosure of evidence of the identity of the informant outweighs—
(a)
any likely adverse effect of the disclosure on the informant or any other person; and
(b)
the public interest in the communication of facts and opinion to the public by the news media and, accordingly also, in the ability of the news media to access sources of facts.
