And at p.340, Lord Atkinson also said this:
A more difficult question, however, remains upon which the authorities cited give little, if any, assistance. It is this: What would be the effect of embodying separable foreign and irrelevant defamatory matter in a libel? Would it make the occasion of the publication of the libel no longer privileged to any extent, or would those portions of the libel which would have been within the protection of the privileged occasion, if they had stood alone and constituted the entire libel, still continue to be protected, the irrelevant matter not being privileged at all and furnishing possible evidence that the relevant portion was published with actual malice. In the absence of all guiding authority the latter would, in my opinion be more consistent with justice and legal principle, and I think it is ,in law, the true result.
39 And at p.348, Lord Shaw of Dunfermline said this:
If, accordingly, and in so far as the communication deals with matter not in any reasonable sense germane to the subject-matter of the occasion, the protection is gone: the occasion with its privilege does not reach a communication upon this foreign and totally unconnected matter. Further, the introduction of such matter into a communication otherwise protected by the occasion may sometimes (this is conceivable) have a bearing upon the issue of whether the other and protected matter was published with express malice.
40 In Horrocks v. Lowe, Lord Diplock, with whom Lord Wilberforce, Lord Hodson and Lord Kilbrandon agreed, said this at p.151:
The exception is where what is published incorporates defamatory matter that is not really necessary to the fulfilment of the particular duty the protection or the protection of the particular interest upon which the privilege is founded. Logically it might be said that such irrelevant matter falls outside the privilege altogether. But if this were so it would involve the application by the court of an objective test of relevance to every part of the defamatory matter published on the privileged occasion; whereas, as everyone knows, ordinary human beings vary in their ability to distinguish that which is logically relevant from that which is not and few, apart from lawyers, have had any training which qualifies them to do so. So the protection afforded by the privilege would be illusory if it were lost in respect of any defamatory matter which upon logical analysis could be shown to be irrelevant to the fulfilment of the duty or the protection of the right upon which the privilege was founded. As Lord Dunedin pointed out in Adam v. Ward [1917] A.C. 309, 326-327 the proper rule as respects irrelevant defamatory matter incorporated in a statement made on a privileged occasion is to treat it as one of the factors to be taken into consideration in deciding whether, in all the circumstances, an inference that the defendant was actuated by express malice can properly be drawn. As regards irrelevant matter the test is not whether it is logically relevant but whether, in all the circumstances, it can be inferred that the defendant either did not believe it to be true or, though believing it to be true, realised that it had nothing to do with the particular duty or interest on which the privilege was based, but nevertheless seized the opportunity to drag in irrelevant defamatory matter to vent his personal spite, or for some other improper motive, Here, too, judges and juries should be slow to draw this inference.
41 I note that in Bellino v. Australian Broadcasting Corporation (1996) 185 CLR 183, Dawson, McHugh and Gummow JJ said this at p.228:
It is true that, at common law, privilege only attaches to those defamatory imputations that are relevant to the privileged occasion. Where a potentially privileged communication consists partly of matters relevant to the privilege and partly to matters that are not relevant, qualified privilege only attaches to that part which is relevant to the occasion. Moreover, the inclusion of the irrelevant part in the communication forms evidence of malice and can destroy the privilege attaching to the relevant part.
42 Their Honours went on to quote part of the passage given above from Lord Finlay LC's judgment in Adam v. Ward. It was submitted by Mr. McClintock that that passage indicated a rejection of what Lord Diplock said in Horrocks v. Lowe.
43 In my opinion, the correct principle to be drawn from the passages I have quoted is that a matter which is irrelevant to and unconnected with the privileged occasion does not have the protection of privilege at all, and that the inclusion of such matter may also base an inference of malice which will deprive even the relevant part of the communication of the protection of privilege. In so far as the passage from Horrocks v. Lowe suggests otherwise, in my opinion it is not supported by Adam v. Ward and is contradicted by the passage quoted from Bellino. However, as noted earlier, I think the cumulative effect of the passages quoted from Adam v. Ward and Horrocks v. Lowe do indicate that, unless malice is inferred, material communicated on the privileged occasion will have the protection of the privilege unless it is truly unconnected with the subject matter of the occasion.
44 In the present case, I am not satisfied that the primary judge was wrong to hold that the defamatory part of the publication was not irrelevant to the subject matter of the privileged occasion. It was in my opinion germane and reasonably appropriate to the occasion to give readers the context of the proceedings in which the decision relevant to occupational health and safety was made, and the part of the publication complained about really does no more than to indicate the nature of the proceedings and the result of the proceedings, so that the part of the judgment relevant to occupational health and safety is put in a context. Certainly, the part complained about is not such as could possibly ground an inference of malice.
45 Turning to the third matter raised by Mr. McClintock, in my view the requirement that a report of court proceedings be accurate in order that it have the protection of qualified privilege is a requirement that applies to one particular category of qualified privilege, namely that applicable to reports of court proceedings made to the public in general. It is not an additional requirement imposed over and above the other requirements for the reciprocal duty and interest category of qualified privilege.
46 For example, if there was an enquiry by a prospective employer, who was considering placing a prospective employee in a position of trust, made of a person with knowledge of that prospective employee, and the person of whom the enquiry was made knew that the prospective employee had been convicted of an offence involving dishonesty, and that person honestly but mistakenly communicated to the prospective employer that the prospective employee had been convicted of obtaining money by false pretences, whereas the conviction was in fact for larceny by a servant, the qualified privilege would not in my opinion be lost because the communication happened to be an inaccurate report of court proceedings. Viewed in that way, in my opinion none of the passages referred to by Mr. McClintock support a requirement of accuracy in reporting the result of court proceedings in cases where the qualified privilege is the result of a reciprocal duty and interest of the type involved in this case.
47 For those reasons, in my opinion the appeal fails.
