C.2 Relevant Principles
17 The principles to be applied in determining whether a published matter is defamatory have been stated and restated innumerable times: see, generally, Oliver v Nine Network Australia Pty Ltd [2019] FCA 583 (at [19]-[20]); Stead v Fairfax Media Publications Pty Ltd [2021] FCA 15; (2021) 387 ALR 123 (at 127-128 [15]). It is nonetheless worthwhile to draw out a number of propositions which warrant emphasis in the present case.
18 First, the lodestar is what the ordinary reasonable person would understand by the matter in question. As the High Court explained in Trkulja v Google LLC [2018] HCA 25; (2018) 263 CLR 149 (at 160 [31] per Kiefel CJ, Bell, Keane, Nettle and Gordon JJ), the exercise is:
one of attempting to envisage a mean or midpoint of temperaments and abilities and on that basis to decide the most damaging meaning that ordinary reasonable people at the midpoint could put on the impugned words or images considering the publication as a whole.
19 Secondly, as I remarked in Oliver v Nine Network (at [19]-[20]), I am tasked with assessing the impugned matter as a whole, identifying its emphases and tonalities, and considering the latitude it gives to the ordinary reasonable person to draw defamatory inferences. The ordinary reasonable person is, of course, not a lawyer, but rather someone who views the publication "casually and is prone to a degree of loose thinking": Trkulja (at 160-161 [32] per Kiefel CJ, Bell, Keane, Nettle and Gordon JJ).
20 Thirdly, and relatedly, there is a need to focus on the impression the ordinary reasonable person gleans from a matter, particularly in the context of publications made and viewed online. As I said in Kumova v Davison (No 2) [2023] FCA 1 (at [46]) (albeit in the context of matters published on social media), where the Court is concerned with questions of meaning, context is everything. The reader's interaction with publications on available platforms is often transient. A similar observation may be made as to matters published via a news programme broadcast on radio or television.
21 Fourthly, where, as here, the Court is concerned with whether the imputations were in fact conveyed, I am constrained by authority to determine, on the balance of probabilities, that the alleged defamatory meaning was in fact the "single objective meaning" of the words: Australian Broadcasting Corporation v Chau Chak Wing [2019] FCAFC 125; (2019) 271 FCR 632 (at 646-647 [32] per Besanko, Bromwich and Wheelahan JJ); cf Palmer v McGowan (No 5) [2022] FCA 893; (2022) 404 ALR 621 (at 640 [71]-[72]).
22 Fifthly, there is a body of authorities as to imputations concerning investigation, suspicion and guilt: see, by way of summary, Rush v Nationwide News Pty Ltd (No 7) [2019] FCA 496 (at [86]-[88] per Wigney J). In Favell v Queensland Newspapers Pty Ltd [2005] HCA 52; (2005) 79 ALJR 1716, the High Court remarked (at 1720 [12] per Gleeson CJ, McHugh, Gummow and Heydon JJ) that a statement that a person is under investigation, without more, may not suffice to impute guilt. If, however, it is accompanied by an account of the "suspicious circumstances that have aroused the interest of the authorities, and that points towards a likelihood of guilt, then the position may be otherwise": Favell v Queensland Newspapers (at 1720 [12] per Gleeson CJ, McHugh, Gummow and Heydon JJ); Herron v HarperCollins Publishers Australia Pty Ltd [2022] FCAFC 68; (2022) 400 ALR 56 (at 64-65 [31] per Rares J, Wigney J and Lee J agreeing).
23 It may be the case that a statement that a person is being investigated or is suspected of wrongdoing conveys no more than that there are reasonable grounds to suspect or investigate potential guilt: Rush v Nationwide News (at [86] per Wigney J); Lewis v Daily Telegraph Ltd [1964] AC 234 (at 267-268 per Lord Morris of Borth‐y‐Gest). The ordinary, reasonable reader is, as Sir Anthony Mason explained in Mirror Newspapers Limited v Harrison (1982) 149 CLR 293 (at 300), "mindful of the principle that a person charged with a crime is presumed innocent until it is proved that he is guilty". As Wigney J noted in Rush v Nationwide News (at [89]), there is no reason to suppose that these general notions "do not equally apply where the relevant publication concerns a complaint which has been made to, or is being investigated by, a person or body other than the police or the prosecution service", such as, in the present case, the Department of Defence (DOD) and Office of the Special Investigator (OSI).
24 Reference is oftentimes made in submissions on meaning involving publications of allegations of wrongful conduct to the so-called "bane and antidote" principle and the notion of "smoke and fire". It should be said at the outset that there are dangers in fixing upon metaphors in discerning what should be the straightforward factual question of meaning and also to setting down a rigid taxonomy with respect to alleged imputations concerning guilt and suspicion: Australian Broadcasting Corporation v Chau Chak Wing (at 644-645 [28] per Besanko, Bromwich and Wheelahan JJ). In any event, such metaphors, like many of the short-hands used in the law of defamation, are no more than mnemonics which give colour to what is in reality a jury question.
25 As to "bane and antidote", the real point (in contexts such as the present) is whether the reader leaves the publication understanding that the allegation is no more than an allegation (see, for example, Bik v Mirror Newspapers Limited [1979] 2 NSWLR 679). The mere presence of a denial of a defamatory charge does not necessarily prevent the publication being defamatory, for the viewer may be left in the position of having to choose between inconsistent assertions: see P Milmo QC and W V H Rogers (eds), Gatley on Libel and Slander (Thomson Reuters, 11th ed, 2008) 131-132 [3.31]. As noted by Wigney J in Rush v Nationwide News (at [91]), quoting John Fairfax Publications Pty Ltd v Rivkin [2003] HCA 50; (2003) 77 ALJR 1657 (at 1666 [50] per McHugh J), the concept reflects the reality that a "reader is entitled to give some parts of [a publication] more weight than other parts".
26 The "smoke and fire" notion is best explained by quoting the famous remarks of Lord Devlin in Lewis v Daily Telegraph (at 285) (see also Favell (at 1720 [11]-[12] per Gleeson CJ, McHugh, Gummow and Heydon JJ)):
A man who wants to talk at large about smoke may have to pick his words very carefully if he wants to exclude the suggestion that there is also a fire; but it can be done. One always goes back to the fundamental question: what is the meaning the words convey to the ordinary man. You cannot make a rule about that. They can convey a meaning of suspicion short of guilt; but loose talk about suspicion can very easily convey the impression that it is a suspicion that is well founded.
(Emphasis added).
27 Sixthly, it is fundamental that a person who repeats a defamatory statement made by a third party is liable for the publication of it, whether or not it is expressly adopted or endorsed: Corby v Allen & Unwin Pty Ltd [2014] NSWCA 227 (at [139]-[141] per McColl JA, Bathurst CJ and Gleeson JA agreeing).
28 Seventhly, and of some significance for reasons explained below, both parties accepted that the Court is not bound by the precise form of imputations pleaded and, as was explained by Gaudron and Gummow JJ in Chakravarti v Advertiser Newspapers Limited (1998) 193 CLR 519 (at 546), there will usually be no disadvantage in allowing an applicant to rely on meanings comprehended in the meaning pleaded, or a meaning which is simply a variant of the meaning pleaded.
