If, however, the matter complained of is not ex facie defamatory, or does not refer by name to the person alleged to be defamed, and the defamatory character which is attributed to the matter, or the identity of the person defamed, would be apparent only to persons who had knowledge of special circumstances, it is necessary, in order to prove publication, to prove that it was published to a person or persons who had knowledge of those circumstances.
His Honour later said:
This is not to say that the mere fact that the name is not mentioned makes it essential to call a witness to prove that he identified the complainant by the description. To take an example used in argument, in an action against a widely circulated newspaper for an alleged libel upon a plaintiff contained in an article which described him only as "the Prime Minister of Australia", it would be unnecessary to call a witness to prove that he had received the issue of the newspaper and knew who the Prime Minister was. In such a case the nature of the description would be such that special knowledge would be unnecessary to identify the person indicated: Jones v. E. Hulton & Co. [13] . But the less revealing the description the greater the danger of omitting proof of identification. It is hardly necessary to add that it would be, to say the least, imprudent for a plaintiff who expected to obtain substantial damages to abstain from proving the scope of the publication and its effect, in accordance with the usual practice in actions of defamation: cf. Sunkissed Bananas (Tweed) Ltd. v. Banana Growers' Federation Co-operative Ltd. [14] .
It was decided in that case that the plaintiffs, who sued on a report defaming the owners of two buildings without naming them, failed because their identity was not a matter of general notoriety and they omitted to prove that the report was published to persons who would know who the owners were. Jordan C.J.'s statement of the law was followed and applied in Cross v. Denley [15] and more recently in Kruse v. Lindner [16] .
