Proving or disproving serious harm
40 At this point it is useful to address an issue which was debated before the Court, being the manner in which serious harm to reputation might be proved or disproved.
41 By s 10A(1) of the Defamation Act, it is an element of a cause of action for defamation that the publication of a defamatory matter about a person has caused, or is likely to cause, serious harm to the reputation of that person. In the course of the hearing, contested submissions were made about how Mr Peros might go about establishing that. In particular, the existence of the Coroner's report and the subsequent media publicity were initially identified as being hindrances to him. It became evident, however, that there may be difficulties in utilising that material on the question of serious harm as a result of the application of the principle from the decision of Dingle v Associated Newspapers Ltd [1964] AC 371 (Dingle). That principle provides that a defendant cannot rely, in relation to the mitigation of damages, on the fact that similar defamatory statements have been published about the same claimant by other persons: see Lachaux v Independent Print Ltd [2020] AC 612, 627 [22] (Lachaux). It was submitted that the same applies in relation to the establishing of serious harm.
42 Nevertheless, Mr Peros carries the onus of establishing that his reputation has suffered serious harm and, in doing so, he must establish the required degree of causation between the publications complained of and what he claims is the resulting damage. On this topic, Mr McCafferty KC referred to Amersi v Leslie [2023] EWHC 1368 (KB), a decision of Nicklin J in the Media & Communications List. There (at [143] - [163]), his Honour dealt with the progenitor provision of s 10A(1) of the Defamation Act (Qld), being s 1(1) of the Defamation Act 2013 (UK). His Honour identified (at [144]) that serious harm can only be established by reference to "the impact which the statement is shown actually to have had", and that "[i]t depends on a combination of the inherent tendency of the words and their actual impact on those to whom they were communicated": Lachaux at 623 [14]. He further observed (at [145]) that the assessment of serious harm was not a "numbers game", such that publication to a relatively small number of persons may cause very serious harm and whether serious harm has been caused is a matter of evidence. His Honour further accepted (at [146]) that, in cases of mass publication, it was not necessary for a claimant to seek out those who substantially thought less of them because of the defamatory matter, and whether "tangible evidence" of serious harm to reputation is required will depend upon the circumstances.
43 In the course of his Honour's reasons, Nicklin J cited from the decision of Collins Rice J in Sivananthan v Vasikaran [2023] EMLR 7, where her Honour referred to the causation requirement of the serious harm element. Her Honour said at 252 [45] and 255 [56] - [57]:
Section 1(1) uses the language of causation prominently ('caused or is likely to cause'). The 'serious harm' component of libel therefore contains an important causation element, as with any other tort or civil wrong. The starting point is that defendants are responsible only for harm to a claimant's reputation caused by the effect of each statement they publish in the minds of the readership of that statement. A claimant therefore has to establish a causal link between each item he sues on and serious harm to his reputation, actual or likely.
…
The fourth is a point which also arose on the facts in Lee v Brown. Where a libel claimant selects some publications as examples of a wider campaign of allegations by a defendant, that claimant may face a daunting problem of causation. If a defendant has undertaken a protracted course of conduct publicising allegations, a corresponding improbability arises that any member of that public later re-encountering them in published form will be impacted as an effect of that specific publication. The serious harm test is about the impact of an individual publication by a defendant on its readership. If the readership already knows everything about the defendant's view of the claimant contained in the publication from the defendant's own history and course of conduct, it is correspondingly unlikely that the publication will have material impact. There are other torts addressed to campaigns and courses of conduct (such as harassment), but libel is concerned with the effects of individual publications.
The fifth point is related, but distinct. If publication is not only in the context of a well-known dispute between the parties, but to an audience already either partisan or resolutely neutral as between them, then again a claimant may have to work harder to make their case on causation. In a polarised context, it may be less probable that anyone's mind will have been changed either way by the publication. If no-one's mind is changed, then establishing the causation of reputational harm is a problem.
44 From this, the submission was made on behalf of Ms Blackburn that establishing serious harm was an exercise in causation and the onus lay on the claimant to establish as a matter of fact that the publication complained of caused serious harm to them. It was further submitted that the Dingle principle was irrelevant to the causative question, and that the Court would be required to take into account the broader context of the publications about Mr Peros, which would presumably include the Coroner's report and the resultant media reporting. Thus, it was said that the Court could assess those circumstances and it would easily reach the conclusion that by the time the statements alleged in Mr Peros' statement of claim were made, he had no reputation that could be seriously harmed.
45 Conversely, Mr Potter SC submitted that the Dingle principle applied to the assessment of serious harm, such that the circumstances of the Coroner's report and its publication, as well as the media reporting, could not be taken into account. In doing so, he relied on the decision of the Supreme Court of the United Kingdom in Lachaux and, in particular, the reasons of Lord Sumption (with whom the other Law Lords agreed). Lord Sumption (at 623 [14]) identified that a statement is not defamatory merely because of its inherent tendency to cause harm to reputation. Rather, following the introduction of s 1(1) of the Defamation Act 2013 (UK) it must have caused or is likely to cause harm which is serious. He added:
… The reference to a situation where the statement "has caused" serious harm is to the consequences of the publication, and not the publication itself. It points to some historic harm, which is shown to have actually occurred. This is a proposition of fact which can be established only by reference to the impact which the statement is shown actually to have had. It depends on a combination of the inherent tendency of the words and their actual impact on those to whom they were communicated. …
46 In this way, his Lordship observed (at 624 - 625 [17]) that the defamatory character of a statement no longer depends only on the meaning of the words and their inherent tendency to damage a reputation. The claimant must demonstrate, as a matter of fact, that the publication complained of has caused harm and that harm is serious. In the matter before the Supreme Court, the trial judge, Warby J had based his conclusions of serious harm on the scale of the publications, the fact that they had come to the attention of at least one person in the United Kingdom who knew the claimant, that they were likely to have come to the attention of similar persons, and the gravity of the statements themselves. Of this, Lord Sumption opined at 627 [21]:
But I do not accept, any more than the judge did, that his case must necessarily fail for want of such evidence. The judge's finding was based on a combination of the meaning of the words, the situation of Mr Lachaux, the circumstances of publication and the inherent probabilities. There is no reason why inferences of fact as to the seriousness of the harm done to Mr Lachaux's reputation should not be drawn from considerations of this kind. Warby J's task was to evaluate the material before him, and arrive at a conclusion on an issue on which precision will rarely be possible.
47 At 627 - 628 [22] - [24] of Lord Sumption's reasons, his Lordship dealt with, inter alia, whether the Dingle principle applied to the serious harm analysis. In relation to this his Lordship said at 627 - 628 [24]:
The effect of the Dingle rule is to treat evidence of damage to the claimant's reputation done by earlier publications of the same matter as legally irrelevant to the question what damage was done by the particular publication complained of. It has been criticised, but it is well established. It has the pragmatic advantage of making it unnecessary to determine which of multiple publications of substantially the same statement occurred first, something which in the case of a newspaper would often be impossible to ascertain and might differ from one reader to the next. The practical impact of the Dingle rule in the modern law is limited by section 12 of the Defamation Act 1952, which allows a defendant to rely in mitigation of damage on certain recoveries or prospective recoveries from other parties for words to the same effect; and by the operation of the Civil Liability (Contribution) Act 1978. Section 1 of the Act is concerned with the threshold of harm and not with the measure or mitigation of general damage. But both raise a similar question of causation. It would be irrational to apply the Dingle rule in one context but not the other, and no one is inviting us to abrogate it. The judge was therefore entitled to apply it.
48 The correctness of Lord Sumption's observations were not debated in the course of the application such that there is no need to reach any conclusion upon that topic. However, why an evidential rule of pragmatism or policy should necessarily apply to a fact-specific and contextual issue is not self-evident from his Lordship's reasons. The application of the Dingle principle to the statutory obligation to demonstrate serious harm to reputation from the publication complained of is, necessarily, a judicial exegesis on the plain words of the section derived from a rule of evidence. Nevertheless, as such a rule it is only concerned with the way in which the claimant's reputation at the time of publication is proved. It does not suggest that their reputation is not relevant. That reputation, or lack of it, may be established by other means, including the evidence of those who know the claimant and by what they believed about the claimant.
49 Mr Potter SC also referred to the recent decision of McEvoy J in Hun v Aljazeera International, which concerned two applications to have the serious harm element of the claimant's defamation actions determined separately. Relevantly, the claimant, Mr To Hun, had brought two separate proceedings for defamation against Aljazeera International (Malaysia) SDN BHD and others, and Nationwide News Pty Ltd and another. In the first proceedings, Mr Hun sued the Aljazeera respondents on the basis of publications in Australia of certain material that, in broad terms, suggested that Mr Hun had been involved in dishonest and illegal conduct in Cambodia. The publications were alleged to have been through material on the company's website and a documentary which it published on YouTube. In the second proceedings against Nationwide News and another, the respondents were sued on the basis of certain publications in The Australian newspaper and on its website of an article entitled, "Dictator's Nephew and links to crime".
50 The Aljazeera respondents brought their application under r 30.01 of the Rules for the same reason that Ms Blackburn pursued the present application in reliance on it, whilst the Nationwide News respondents sought to rely on both r 30.01 and s 10A(5) of the Defamation Act.
51 Mr Hun pleaded that the publication of the documentary caused serious harm to his reputation and his particulars included the extent of the publication, the viewing of it on the internet, the gravity and scandalous nature of the imputations, the ostracism of his children which was said to have occurred following the publication, and the non-renewal of his visa. A similar plea was made in relation to his defamation claim against Nationwide News. In support of their applications that the serious harm issue be determined first, the respondents submitted, in part, that there was substantial material in the public domain about Mr Hun including allegations of his involvement in drug trafficking and money laundering. It was said that, in such circumstances, the impact of the publications of which Mr Hun complained would be de minimis.
52 In relation to the issue of the assessment of serious harm, McEvoy J accepted (at [41] - [42]) that although the focus should be on the damage to reputation, the Court is to look at the totality of the circumstances, including the seriousness of the imputations conveyed and their inherent tendency to cause harm. In this context, he accepted Lord Sumption's observations in Lachaux to the effect that what had to be shown was actual harm to the claimant's reputation, but that this could be established from "a combination of the meaning of the words, the extent of publication, and the inherent probabilities". His Honour also observed that the nature and extent of the publications in question was relevant to whether a separate determination of the issue of serious harm should occur. He opined at [43]:
It may be observed at a level of generality that it is difficult to see how it would ever be appropriate to deal with serious harm as a separate question where there are mass media publications which, at least arguably, convey imputations of the most serious kind.
53 His Honour was here identifying that the separate hearing procedure in r 30.01 of the Rules was generally inappropriate to resolve the issues which would arise where serious harm is alleged to have occurred by reason of mass media publications of serious imputations. The rule contemplates that the trial of separate questions should be confined to reasonably stark cases and not those where there could be substantial contested facts which involve evidence which would need to be repeated at trial, or would require the same deponent to return at trial. The issues which arose before his Honour would not normally justify the adoption of the r 30.01 process.
54 In the scenario before McEvoy J, it was also considered that there was a potentially large viewership of the material complained of and there would likely be disputes about the evidence and what it disclosed. On that basis, his Honour concluded (at [48]) that the inquiry into serious harm would not be straightforward and would extend to the gravity of the imputations, their inherent tendency to cause harm to the claimant's reputation, the extent of the publications including the extent of their spread on the "grapevine", the identity of the persons to whom it was spread, the claimant's personal circumstances, evidence of the actual impact of the publications, and the inherent probabilities involved.
55 In relation to the existence of historical material in the public domain which demonstrated that the claimant had a bad reputation at the time of publication, his Honour held that its admissibility at trial would be a contestable issue and he referred to the Dingle principle and its acceptance in Australia in Australian Broadcasting Corporation v Chau Chak Wing (2019) 271 FCR 632, 663 - 664 [94].
56 Returning to the present case, whether the Coroner's report and the media reports, or either of them, are admissible of themselves to disprove serious harm is an open question. It is possible, even likely, that the Dingle principle does not necessarily apply to, or apply with the same force to, each of the items of evidence. Although the question was not fully ventilated before this Court, some doubt must exist as to whether, in the circumstances of this case, the Dingle principle would exclude reception of the Coroner's report. In relation to that principle, it has been held that judicial findings which are in the public domain may be admissible: see Channel Seven Sydney Pty Ltd v Mahommed (2010) 278 ALR 232, 285 [253]. Though the Coroner's report is not a judicial determination, on the essentially factual question of whether Mr Peros might have suffered serious harm to his reputation, it is not immediately self-evident that the publication of the findings of an organ of State which followed a process to which the rules of natural justice applied, and at which Mr Peros appeared, would be excluded in the same manner as the publications of media outlets are. The reasoning in Channel Seven Sydney Pty Ltd v Mahommed by no means excludes such material and, though the findings might not fit within the concept of "judicial findings", it is difficult to detect any relevant distinction. Further, on the basis of Mr Peros' submissions, a finding of a Royal Commission about a claimant concerning the specific incident which is the subject of the alleged defamation would be inadmissible to establish a lack of reputation. For present purposes, it remains an open question which will need to be determined following fulsome submissions.
57 The consequence of the foregoing is that the metes and bounds of the application of the Dingle principle in the present case are unclear. The particular issues in contest are unknown, the evidence which either party will adduce is unknown, and there is doubt about the admissibility of the evidence which may be called. These features militate against the use of the procedure provided by r 30.01 to resolve the question of whether Mr Peros has suffered serious harm.
58 Reference was also made by the parties to the decision in Selkirk v Hocking, where O'Callaghan J granted an application for a separate hearing of the question of serious harm. However, the known circumstances in that case did not involve the abovementioned difficulties. There, the publication in question was to a very limited audience of no more than three persons, and the claimant had admitted in separate proceedings that she had engaged on other occasions in the same dishonest conduct which was the subject of the alleged defamation. In other words, the scope of the issues surrounding the determination of whether the claimant had suffered serious harm was limited and obviously so. It ought to be noted that in the subsequent determination by O'Callaghan J in Selkirk v Hocking (No 2) [2023] FCA 1085 [21], reliance was placed on the observations of the United Kingdom Court of Appeal in Lachaux v Independent Print Ltd [2018] QB 594, 620 [79], where Davis LJ (with whom Sharp and McFarlane LJJ agreed) held:
Whether in any given case the imputation is of sufficient gravity as of itself to connote serious reputational harm (quite apart from the question of consequential or special damage) should therefore normally be capable - where the question of serious harm is in issue and is not appropriately to be left to trial - of being relatively speedily assessed at the meaning hearing. If it is, nevertheless, desired by a defendant to put in evidence at an interlocutory stage designed to show that there is no viable claim of serious harm the summary judgment procedure under CPR Pt 24 is available if the circumstances so justify. There may, for instance, be cases where the evidence shows that no serious reputational harm has been caused or is likely for reasons unrelated to the meaning conveyed by the defamatory statement complained of. One example could, for instance, perhaps be where the defendant considers that he has irrefutable evidence that the number of publishees was very limited, that there has been no grapevine percolation and that there is firm evidence that no one thought any the less of the claimant by reason of the publication. …
59 The difference in the circumstances in that case and the present highlight the difficulties which might be encountered were an attempt to be made to resolve the question of serious harm by use of the r 30.01 procedure.
