89 First, the common law's recognition in the 'newspaper rule' of the public interest in the free flow of information by the imposition of restraints on the disclosure of the identity of a media proprietor's or journalist's confidential source of information, at the interlocutory stage of defamation and related actions, notwithstanding the relevance of the identity of the source to the issues to be tried. Secondly, whether, in the particular case, the information which the source has revealed, on a confidential basis, appears to be a matter of genuine public interest, including whether the information discloses an iniquity. Thirdly, the manner in which the information was obtained, including whether it was obtained by lawful means. Fourthly, the pleadings in the pending proceedings, including the elements of the plaintiff's causes of action, any admissions by the defendant, and the apparent reasonableness or unreasonableness of any denials or non-admissions in the defence. Fifthly, whether the plaintiff is likely to experience real and substantial difficulty in proving any element of any cause of action without the disclosure of the identity of the confidential source. Sixthly, whether any difficulty in proof as a result of the non-disclosure of the identity of the source is likely materially to complicate the trial or unduly to extend its length, to involve significant expense for the plaintiff (especially an indigent plaintiff or a plaintiff with limited financial resources) or to cause significant inconvenience to a proposed witness. Seventhly, the apparent importance to the plaintiff and generally of the rights which he or she seeks to vindicate in the pending proceedings.
