Should the evidence have been excluded under s 135?
61 Section 135 relevantly provides that a court may refuse to admit evidence if its probative value is substantially outweighed by the danger that the evidence might be unfairly prejudicial to a party. At trial Mr Riordan said that because Mr Gidman's evidence was unsubstantiated, (1) the evidence was of limited probative value and (2) Hay was prejudiced because Mr Riordan was unable to effectively cross-examine Mr Gidman, not knowing the factual bases for his evidence. It would be unfair, Mr Riordan argued, to be forced to "blindly" cross-examine Mr Gidman, at the risk of prompting Mr Gidman to elaborate on his evidence and make out La Trobe's case.
62 The judge rejected this submission, holding that none of Mr Gidman's evidence would prejudice Hay. An appeal court may only interfere with a judge's discretionary decision consistently with the principles in House v R (1936) 55 CLR 499; see also Collaroy Services Beach Club Ltd v Haywood [2007] NSWCA 21, [49]. In my view, there has not been any error demonstrated in the judge's exercise of his discretion that would justify overturning his decision. To the contrary, if I were to consider the matter afresh, I would admit the evidence. Too much, in my view, is nowadays made of the need to have at hand every piece of information imaginable to enable effective cross-examination to take place. Perhaps there are a handful of cases where the discretion to refuse evidence should be exercised. But that can hardly be so here where the evidence is straightforward and could easily be challenged if untrue.
63 It must also be remembered that to exclude evidence under s 135, there must be compelling circumstances for the exclusion. The discretion should only be exercised where the prejudice substantially outweighs the probative value of the evidence, for only then will the admission of the evidence cause "unfair prejudice".
64 It is true that the meaning of the term "unfair prejudice" has been somewhat contentious. The ALRC explained the risk of unfair prejudice as being the danger that the evidence might be used in an improper, perhaps emotional, way: ALRC, Evidence (Interim) Report, Report no 26 (1985), v 1, [644]. Clearly, a risk of that kind is much greater in the context of jury trials. However, there are also numerous authorities that suggest that an unfair prejudice may arise from procedural considerations: see Odgers, Uniform Evidence Law (9th ed, 2010) [1.3.14560].
65 Mr Riordan refers to two authorities in support of his submission. The first is the Guide Dogs case. The applicant, a guide dog organisation, argued that the terms "seeing eye dog" and "guide dog" were particularly associated with the applicant. It claimed that the respondent, another guide dog association, had committed the tort of passing off and had contravened s 52 of the TPA by using the term "seeing eye dog" in relation to its services. The Chief Executive Officer of the defendant gave evidence the following evidence:
19. Since I became chief executive officer of the Association, I have had extensive dealings with members of the public and the media in New South Wales and the ACT in relation to guide dogs. I have travelled to all States of Australia except Western Australia and the Northern Territory to represent the Association on [sic], and have had dealings with members of organisations interested in providing assistance to blind and vision impaired persons. All persons with whom I have so dealt have used the terms "seeing eye dog" and "guide dog" interchangeably and have not used such terms to distinguish between any particular organisation or its method of training guide dogs.
20. Often acquaintances of mine, who know that I am the chief executive officer of the Association, will, in general conversation, ask me a question in words to the effect: "How are the seeing eye dogs?" or "How are the guide dogs?" or "How are the blind dogs?". The term "guide dogs", "seeing eye dogs" and "blind dogs" are used about equally by persons speaking to me in these conversations. Recently, in a discussion with friends at my golf club, one of my friends was complaining about his family dog and another said words to the effect: "You should give it to Joe, he will turn it into a seeing eye dog."
Objection was made to the final sentence of paragraph 19 and all of paragraph 20.
66 Sackville J determined (at 532) that the final sentence of paragraph 19 should be excluded under s 135, but that paragraph 20 should not be excluded. In respect of the final sentence of paragraph 19, Sackville J said (at 531-2) that the evidence was of limited weight, the witness having made no attempt to recount the nature and context of the conversations. Without having that context, the plaintiff did not have a full and fair opportunity to test the opinion in cross-examination, particularly given that the opinion went to the most critical issue to be resolved. On the other hand, he said (at 532-3) that the evidence in paragraph 20 gave sufficient substance of particular conversations (even though some were not precisely identified) and did not purport to characterise their effect in terms of the issues in the case.
67 A number of observations can be made about the Guide Dogs decision. The first is that the decision to exclude the last sentence of paragraph 19 was based on Sackville J concluding that it concerned opinions about the effect of conversations. The requirements for giving evidence about the effect of conversations are more stringent than for most other forms of evidence. Professor Wigmore explained that when a witness testifies about an ordinary act or occurrence, there is no requirement, for admissibility purposes, that the whole of the deed or occurrence be offered or taken together. On the other hand, where the evidence reproduces a conversation, it is necessary for at least the substance of the conversation to be reproduced so as to allow it to be properly interpreted in context: 7 Wigmore on Evidence (Chadbourn rev 1978) Ch 73. The second observation is that Sackville J admitted the evidence in paragraph 20, notwithstanding that full particulars were not provided about most of the conversations. So long as the substance of the conversations was apparent, there was no unfair prejudice to the applicant in not knowing the precise particulars of the conversations, such as where and when they took place.
68 The second case upon which Mr Riordan relied was another decision of Sackville J, Seven Network Ltd v News Ltd (No 8) (2005) 224 ALR 317. An employee of the applicant, Seven Network, gave contentious evidence about his assessment that Seven had a number of strategic advantages in adapting to developments in the emerging pay TV market. The employee's opinions about those advantages were high-level and abstract in nature. The respondents accepted that the evidence was admissible to the extent that it showed that the witness held the expressed opinions. However, the respondents argued that the evidence should be excluded if used to prove the truth of the belief or the facts relied upon in forming that belief. This was because the evidence was effectively expert evidence tendered without complying with the requirements governing the admissibility of expert evidence, as to which see Makita (Aust) Pty Ltd v Sprowles (2001) 52 NSWLR 705. Sackville J accepted the respondents' argument. He noted (at [22]-[24]) that the witness' opinions concerned highly complex and contentious issues, without divulging any basis for those opinions. Given the very large volume of documents in the case, he said it would be difficult to test in cross-examination any further evidence ascertained about the basis of the opinions.
69 In my view, the cases upon which Mr Riordan relied are far removed from the present case. It is important that Mr Gidman's evidence be read as a whole and in context. He testified as to various matters regarding the opportunities for La Trobe to invest in alternative mortgage-backed loans at the time it lent money to Jet, the terms on which such loans might have been made, and the fact that opportunities were foregone as a result of lending to Jet. The evidence has clear limitations, which both Mr Gidman and counsel for La Trobe frankly conceded. Some of the evidence could not be substantiated through documents, particularly in relation to loan rejections. Some of the evidence was not as specific as it might have been, such as when Mr Gidman could not recall particular instances of loans that were rejected.
70 But there is nothing particularly unusual about Mr Gidman's evidence. It is no different to any other evidence commonly given in the absence of documentary evidence and without perfect recollection. Counsel for Hay could have responded in a variety of ways. For example, he might have challenged the credibility of Mr Gidman in cross-examination, if such a course were warranted. He might have asked questions of Mr Gidman about ambiguities in his evidence or about any inconsistencies between his evidence and other available evidence. Alternatively counsel could have chosen not to cross-examine Mr Gidman at all, and submit that La Trobe had not discharged its onus of proof. Indeed, this is, in effect, what happened at trial, with only limited questions being asked to confirm that Mr Gidman could not recall specific loan applications that had been rejected.
71 Where a litigant faces evidence from his/her opponent that is in some respects ambiguous or unsubstantiated, counsel has a strategic choice to make about how to deal with the shortcomings. Counsel may choose to explore and seek to expose those shortcomings in cross-examination, at the risk of allowing the witness to remedy the position through further evidence. Alternatively, counsel may choose to leave the evidence as is. To be faced with a strategic decision is not to be burdened with a forensic disadvantage. The possibility of helping an opponent make out his/her case is one of the risks of cross-examination.
72 I appreciate there may be some cases where the witness, having given the barest of evidence in chief, has the potential to "ambush" an opponent with new, unanticipated evidence under cross-examination and for which there is no reasonable opportunity to test. In Seven Network (No 8), for example, given the volume of documents and the complexity of the issues involved, there was clearly a risk of ambush. Similarly, in Guide Dogs there was such a risk where the witness made a bald statement regarding the effect of numerous conversations without providing any context to those conversations (although it is noteworthy that further evidence was allowed where relatively limited substance was given about the conversations).
73 This case did not present the risk of ambush. Mr Gidman gave detailed evidence supported, where possible, by lengthy documentation attached to his witness statement. It was clear that, in some respects, Mr Gidman simply could not give more specific evidence and, to that extent, there was nothing unexpected that was likely to arise in cross-examination. The issues about which Mr Gidman gave evidence were well understood and, where further clarification might have been given, it would hardly have come as a surprise to counsel. For example, it is true, as Mr Riordan pointed out, that Mr Gidman did not directly explain how, on the one hand, La Trobe had foregone loan opportunities due to lending money to Jet while, on the other, La Trobe's financial statements recorded substantial cash at hand. One possibility, which is clearly averted to by Mr Gidman in his witness statement, is that the cash was required to be held for liquidity purposes. This, perhaps, was not spelt out by Mr Gidman as well as it could have been, but that is not to suggest that counsel suffered a forensic disadvantage. Similarly, it is true that Mr Gidman did not directly state that, after lending to Jet, La Trobe rejected loan applications due to lack of funding. Mr Gidman did say, however, that (1) loans had been rejected and (2) loan applications can be rejected due to insufficient funds. Again, if counsel had cross-examined about this, it would hardly have come as a surprise if Mr Gidman had clarified his position unfavourably for Hay's case.
