Principles on the operation of section 97
27 Both counsel relied upon a number of authorities in support of their contentions about the operation of s 97 of the Evidence Act. It is appropriate to begin with the most authoritative decision, that of the Full Court of this Court in Jacara v Perpetual Trustees WA Ltd (2000) 106 FCR 51; [2000] FCA 1886 (Jacara), which considered the operation of s 97 in some depth. While both counsel referred to this decision, Mr Sheahan placed particular reliance upon it. In Jacara, the applicant (Jacara) claimed it had been induced to enter into a lease of a kiosk in a shopping centre by a series of representations allegedly made to it by a Ms Kelly, who was an agent of Perpetual Trustees WA Ltd, the proprietor of the shopping centre concerned. The critical representations were allegedly made to a Mr Williams, who was associated with Jacara. They were to the effect that there would be a substantial increase in the number of customers attending the shopping centre, and therefore Jacara's turnover, following its redevelopment. For present purposes, the pertinent question raised on the appeal was whether the trial judge had erred in excluding evidence of representations to similar effect allegedly made by Ms Kelly to five other persons who were also contemplating entering into leases of shops in the redeveloped shopping centre. The Full Court concluded that the trial judge did not so err and dismissed the appeal.
28 Sackville J delivered the primary decision and Whitlam J (at [1]) and Mansfield J (at [108]) agreed. In the course of his reasons, Sackville J set out: the apposite provisions of the Evidence Act (at [17]-[24]); the legislative scheme in the Evidence Act governing tendency evidence (at [47]-[53]); the common law position on similar fact or propensity evidence (at [68]-[71]) and the test for "significant probative value" under s 97 (at [72]-[76]). It may also be noted that there was an issue in Jacara as to whether s 97 of the Evidence Act governed the evidence concerned at all (see at [54]-[67]). As is noted above (at [2]), no such issue arises in this case.
29 It is convenient to set out a summary of the relevant principles that can be extracted from his Honour's comprehensive and detailed examination in Jacara of the operation of s 97 and the other related provisions of the Evidence Act. They are as follows:
(a) the effect of s 56 of the Evidence Act is that irrelevant evidence is inadmissible in a proceeding while relevant evidence is admissible, except as otherwise provided by the Evidence Act: see at [47];
(b) under s 55(1), relevant evidence is that evidence which, if it were accepted, could rationally affect the assessment of the probability of the existence of a fact in issue in a proceeding: see at [47];
(c) the definition of "relevant evidence" requires a minimal logical connection between the evidence and the fact in issue. However, the relevant evidence does not need to render a fact in issue probable, or even sufficiently probable. Instead, it is enough if it only makes the fact in issue more probable, or less probable, than it would be without the evidence, ie if it affects its probability: see at [47];
(d) relevant evidence is only excluded if one of the exclusionary rules applies, or if the Court exercises a discretionary power to exclude the evidence: see at [48];
(e) the tendency rule in s 97 of the Evidence Act is a contingent exclusionary rule in the sense that the tendency evidence is excluded only if the Court forms a view that the evidence would (now "will": see at [30] below) not have significant probative value: see at [48];
(f) the Evidence Act was not intended to be a mere codification of the common law rules of evidence. Instead, it was intended to make, and did make, substantial changes to the law of evidence: see at [50];
(g) the tendency rule in s 97(1) of the Evidence Act departs from the more relaxed common law approach to the admission of similar fact evidence in civil proceedings set out in authorities such as Sheldon v Sun Alliance Australia Ltd (1989) 53 SASR 97: see at [68]-[71]. Thus, under s 97(1) of the Evidence Act, even if the evidence is relevant, it will not be admissible if the Court thinks that the evidence would (now "will": see at [30] below) not have "significant probative value": see at [72];
(h) for the evidence to have "significant probative value", more is required than mere statutory relevance (under s 55 (see above)) but something less than a "substantial" degree of relevance is required: see at [73];
(i) this means that the evidence has to be "important" or "of consequence" in establishing the fact in issue, or that it has to be "clearly and strongly probative of the relevant fact in issue": see at [73] and the cases cited; and
(j) however, the statutory language provides the standard that has to be applied and statements in authorities (such as cited above) are not to supplant that statutory language: see at [74].
30 Before identifying how Sackville J proceeded to apply these principles in Jacara, it is convenient to note that s 97(1) of the Evidence Act has been amended since the decision in Jacara. While that amendment was achieved by repealing s 97(1) in its entirety and replacing it with a new section, the changes to it were not as radical as this legislative approach might otherwise suggest. In fact, only three words were changed: the word "if" at the end of the introductory words to the provision was changed to the word "unless"; the word "or" between sub-sections (a) and (b) was changed to the word "and"; and the word "would" in the first line of sub-section (b) was changed to the word "will": see Evidence Amendment Act 2008 (Cth).
31 The background to these amendments is recorded by Buchanan J in Astram Financial Services Pty Ltd v Bank of Queensland Ltd [2010] FCA 1010 at [235]-[238]. In this process, his Honour quoted from the Explanatory Memorandum where the purpose of the amendments is described (see at [238]): "[t]he amendment does not change the substantive law, but makes the provision easier to understand". Taking into account the changes made by these amendments (at [30] above), I consider that the Legislature has achieved this purpose. I therefore agree with the observation in Odgers S, Uniform Evidence at Law (10th ed, Thomson Reuters) (at 1.1.60) that: "The provision has been amended to make it clear that the onus is on the party seeking to have the evidence ruled admissible to persuade the court that … the evidence 'will' have 'significant probative value'." Otherwise, I do not consider the principles on the operation of s 97(1) of the Evidence Act as set out in Jacara (above) have been affected by these amendments.
32 In Jacara, Sackville J concluded (at [77]-[82]) that the trial judge did not err in rejecting the evidence of the five other persons as to what Ms Kelly had allegedly said to them. In his submissions, Mr Sheahan relied upon the two factors specifically identified by his Honour: the differences in the accounts and the period of time that had elapsed. Those factors were summarised by his Honour (at [81]) as follows:
In my view, it was well open to the primary Judge to conclude that the various accounts differed among themselves and from Mr Williams' version to such an extent that the evidence could not be said to have significant probative value on the facts and issues. This conclusion is reinforced by the fact that the conversations with the five tenants are said to have occurred some four to twelve months after the dealings with Mr Williams and Ms Kelly.
33 Mr Sheahan submitted that, in this case, the corresponding factors were even more remote than those in Jacara. He submitted that the representations were made by a range of different Storm financial advisers, rather than one; they were made over a period of many years (from 1996 to 2008), rather than four to twelve months; and they were different in content and effect and made in different market circumstances. As a consequence, he submitted there was all the more reason why the tendency evidence in this case was not significantly probative of the facts in issue.
34 Mr Campbell responded that this case was different from Jacara. This was so because, in Jacara, the factual accounts were diverse and they did not go to the central issue, whereas in this case, all of the representations made were to the same effect: there was "no risk" of investing with Storm. Furthermore, he submitted they go to the central issue as to whether representations of this kind were made by Ms Seymour and Mr Drummond to Mrs Richards.
35 Both counsel relied upon a number of other authorities, in particular: Mr Campbell on Trifunovski and Twynam Pastoral Co Pty Ltd v AWB (Australia) Limited [2008] FCA 1922 (Twynam); and Mr Sheahan on Australian Competition and Consumer Commission v CC (NSW) Pty Ltd (1999) 92 FCR 375; [1999] FCA 954 and DF Lyons Pty Ltd v Commonwealth Bank of Australia (1991) 28 FCR 597 (DF Lyons). Since the principles in relation to the operation of s 97 of the Evidence Act have been authoritatively outlined in Jacara, it is unnecessary to consider any of these decisions for the purpose of identifying those principles. Furthermore, as Gummow J said in DF Lyons (at 607), "each case has to be considered with close regard to its particular circumstances". This can be aptly demonstrated from a brief consideration of the decisions in DF Lyons and Twynam, both of which, unlike the other two decisions above, involved claims for misleading or deceptive conduct under s 52 of the Trade Practices Act 1974 (Cth). In DF Lyons, Gummow J rejected as similar fact evidence on common law principles the evidence of three persons to whom similar statements had been made about foreign currency loans, at about the same time, by Mr Green, the CBA bank official concerned. It was Mr Green who had allegedly made the misleading or deceptive representations to Mr Lyons, one of the applicants, about the same subject matter. His Honour's conclusions about the admissibility of that similar fact evidence was as follows (at 607):
In the present case, Mr Green had dealings with various customers of the Bank at Taree concerning foreign exchange loans and they took place in the period in which he was dealing with Mr Lyons. In that sense, there was an underlying unity in Mr Green's activities, but as one might expect, the dealings with customers varied with the particular circumstances as they arose. The nature of the causes of action propounded by the applicants means that specific representations must be established. That is why in the oral evidence of Mr Lyons, both in chief and in cross-examination, great attention was paid in eliciting what was or was not said in precise terms on particular occasions. As a matter of ordinary experience of human behaviour, the evidence which the applicants seek to lead would not tend to prove the making of the representations upon which the applicants rely.

36 On the other hand, in Twynam, Jagot J admitted as tendency evidence under s 97 of the Evidence Act the affidavit evidence of four persons who deposed to having conversations with a Mr Adams about the sale of wheat at about the same time as he (Mr Adams) allegedly made the misleading or deceptive representations to Mr Setter about the same subject matter. While her Honour noted a number of differences in the various conversations, she was nonetheless persuaded by the "striking similarities" between the critical parts of them. Her Honour's conclusion that this tendency evidence should be admitted was as follows (at [13]):
Despite these differences there are striking similarities in respect of the essential allegation in paragraph 12(d) of the statement of claim and Mr Setter's evidence that if the applicant did not buy wheat "now" there would be none left until the next harvest in October 2003. First, it is apparent that the disputed conversations are all said to have occurred in late October or early November 2002 and thus are proximate in time. Secondly, the disputed conversations all involve the respondent's customers or potential customers for the purchase of grain. Thirdly and most importantly, each conversation refers not only to the availability of wheat or grain but to the need to buy now as either no grain would be available until October 2003 (Mr Vickery and Mr Rowland) or grain could become unavailable (Mr Gillogly and Mr Roberts). Hence, the time, context and essential or critical content of the conversations are all remarkably similar. For these reasons I consider that the disputed evidence, taken together with Mr Setter's evidence, has significant probative value within the meaning of s 97 of the Evidence Act (at least in its current form) and is provisionally relevant. The disputed evidence will involve additional time but its probative value is not substantially outweighed by any undue waste of time. As such, I do not accept that it should be excluded under s 135(c).
(Emphasis added)
37 Not surprisingly, Mr Sheahan placed particular reliance on the conclusion in DF Lyons and Mr Campbell placed particular reliance on the conclusion in Twynam. However, in relation to Twynam, Mr Sheahan also pointed to at least two factual distinctions which he submitted were significant in this case. They were: that in Twynam, the same officer of the respondent (Mr Adams) was involved in all of the conversations; and all of the conversations occurred in a short period of time, in late October and early November 2002.
38 Given the more relaxed approach taken to the admission of similar fact evidence in civil proceedings according to common law principles as identified in Jacara (see at [29(g)] above), one might have expected the opposite results in these two cases. This underscores the importance of the statement above (at [35]) that one must look closely to the particular factual circumstances of each case. Accordingly, with all these principles in mind, I will now turn to consider the particular factual circumstances of this case.
