"46 Taken in isolation, the last sentence in the comment made by senior counsel for the respondents correctly stated the meaning of business defamation. However, the comment as a whole was both misleading and, in my opinion, incorrect. It did not draw the jury's attention to the distinct nature of business defamation. In particular, the comment did not inform the jury that there could be business defamation even though the defamatory statement did not lower the defamed person in the estimation of right-thinking members of the community. Accordingly, although I do not agree that the meaning of what the respondents' senior counsel said to the jury was quite as alleged by the appellant, the jury needed careful directions to ensure that they were not left with an erroneous or misleading understanding, either of the law or the way in which the appellants put their case.
...
48 The deficiency in her Honour's directions, on the appellants' submission, was that, having explained to the jury the usual meaning of 'defamatory', that is, that generally a statement is defamatory if it has the tendency 'to lower a person in the estimate of ordinary right-thinking members of the community', her Honour then stated that 'equally', 'defamatory' bore a meaning of 'having a tendency to injure the plaintiff in his or her profession or trade by the suggestion of unfitness or incompetence' (emphasis added). Counsel for the appellants submitted that, by the use of the word 'equally', her Honour left it open to the jury to find that, in this case, they could find the matter in the alternative, so that, if they concluded that the appellants were not lowered in the estimate of ordinary right-thinking members of the community by the imputations in the article, then they would fail.
49 Senior counsel for the respondents contended that the appellants were precluded from complaining about the direction because, her Honour having indicated the direction that she proposed to give to the jury following Mr Evatt's request and, having given a direction in respect of which Mr Evatt then made no complaint, the appellants were precluded from now raising the matter: see Alford v Magee [1952] HCA 3; (1952) 85 CLR 437. The respondents also contended that the direction given by her Honour was not materially different from that which she had proposed during the course of discussion with counsel. Finally, they argued that, in any event, the direction was not erroneous. The respondents submitted that it was open to them to defend the case on the basis that defamatory meaning in this case could, if the jury so decided, bear its general meaning of lowering a person in the estimation of right-thinking persons, so that it was correct for her Honour to direct the jury as to both meanings. Finally, senior counsel for the respondents submitted that, in any event, her Honour had pointed out that not only were the two meanings 'equally' available, but also said, 'importantly', for the purposes of this case, business defamation was alleged.
50 It is convenient to deal first with these last two submissions. In my opinion, the direction given by her Honour was wrong. It was incumbent upon her Honour to direct the jury that in the case of a business defamation, it did not matter whether the published material lowered the person in the eyes of right-thinking members of the community. Her Honour did not give that direction. Indeed, by directing the jury first as to the general meaning of defamation and then by 'equally' referring to a business defamation, without adding the important qualification to which I have just referred, her Honour gave a direction that was wrong in law. In the present case, the error was likely to have been more serious because of the strong and almost uncompromising address by senior counsel for the respondents in his focus upon non-business defamation. As I have already explained, his reference to business defamation at the end of his address was itself erroneous in any event, and did not diminish the persistent reliance upon the irrelevant form of defamatory meaning in this case."
