21 It is true that the trial judge did not say why the evidence was not convincing. It is also not clear whether the trial judge actually rejected the evidence. But that obscurity does not alter the fact that when the judgment is read as a whole, reasons can be found in it for the conclusion of which the plaintiff complains. Whether they are satisfactory reasons is the next question for consideration.
22 In essence, the question is whether the reasons given by the trial judge are so unsatisfactory in point of validity as to justify an order for a new trial. In oral argument, the issue was posed as being whether the trial judge had failed to use or abused a position of advantage enjoyed by him in relation to the hearing of the testimony of the witnesses.
23 While the requirement in civil cases that the trier of fact be satisfied on the balance of probabilities has been called an undemanding standard, it has some reality. Traditionally there are two approaches to its application. One is to demonstrate that the odds of the fact existing or the event happening which the plaintiff is seeking to establish are at least fifty one to forty nine (Davies v Taylor [1974] AC 207 at 219). In view of the inherent unlikelihood of a Mitre 10 salesman saying what the plaintiff alleged, that criterion could not be satisfied, but, as the trial judge said, the conversation could have happened, despite its improbability. This requires the trier of fact to turn to the other approach. On that approach, the trier of fact must
"feel an actual persuasion of its occurrence or existence before it can be found. It cannot be found as a result of a mere mechanical comparison of probabilities independently of any belief in its reality. [At] common law it is enough that the affirmative of an allegation be made out to the reasonable satisfaction of the Tribunal." ( Briginshaw v Briginshaw (1938) 60 CLR 336 at 361-2 per Dixon J; see also Jones v Sutherland Shire Council [1979] 2 NSWLR 206 at 227 per Mahoney JA).
25 The trial judge did not find that the conversation occurred and did not find that it did not occur. Rather he took a third course, which was an available one. In Rehsa Shipping Co SA v Edmunds [1985] 1 WLR 948 at 955-6; [1985] 2 All ER 71 Lord Brandon of Oakbrook said:
"the judge is not bound always to make a finding one way or the other with regard to the facts averred by the parties. He has open to him the third alternative of saying that the party on whom the burden of proof lies in relation to any averment made by him has failed to discharge that burden. No judge likes to decide cases on burden of proof if he can legitimately avoid having to do so. There are cases, however, in which, owing to the unsatisfactory state of the evidence or otherwise, deciding on the burden of proof is the only just course for him to take."
26 In a case of the antiquity of the present one, the trial being over four years after the events in issue, it is quite understandable that the trial judge would find it impossible to come to a conclusion one way or the other.
27 It is also necessary to remember that the appeal is by way of rehearing: Supreme Court Act 1970 s 75A(5). It is not a trial de novo, or a trial of the case afresh on the record. The plaintiff bore the burden in the appeal not merely of showing that on the facts that his contentions might be available but of showing that the trial judge's conclusions ought to be reversed.
28 One other background matter must be borne in mind. In Watson v Foxman (1995) 49 NSWLR 315 at 318-319, McClelland CJ in Eq said:
"Where, in civil proceedings, a party alleges that the conduct of another was misleading or deceptive, or likely to mislead or deceive (which I will compendiously describe as 'misleading') within the meaning of s 52 of the Trade Practices Act 1974 (Cth) (or s 42 of the Fair Trading Act ), it is ordinarily necessary for that party to prove to the reasonable satisfaction of the court: (1) what the alleged conduct was; and (2) circumstances which rendered the conduct misleading. Where the conduct is the speaking of words in the course of a conversation, it is necessary that the words spoken be proved with a degree of precision sufficient to enable the court to be reasonably satisfied that they were in fact misleading in the proved circumstances. In many cases (but not all) the question whether spoken words were misleading may depend upon what, if examined at the time, may have been seen to be relatively subtle nuances flowing from the use of one word, phrase or grammatical construction rather than another, or the presence or absence of some qualifying word or phrase, or condition. Furthermore, human memory of what was said in a conversation is fallible for a variety of reasons, and ordinarily the degree of fallibility increases with the passage of time, particularly where disputes or litigation intervene, and the processes of memory are overlaid, often subconsciously, by perceptions or self-interest as well as conscious consideration of what should have been said or could have been said. All too often what is actually remembered is little more than an impression from which plausible details are then, again often subconsciously, constructed. All this is a matter of ordinary human experience.
Each element of the cause of action must be proved to the reasonable satisfaction of the court, which means that the court 'must feel an actual persuasion of its occurrence or existence'. Such satisfaction is 'not … attained or established independently of the nature and consequence of the fact or facts to be proved' including the 'seriousness of an allegation made, the inherent unlikelihood of a given description, or the gravity of the consequences flowing from a particular finding': Helton v Allen (1940) 63 CLR 691 at 712.
Considerations of the above kinds can pose serious difficulties of proof for a party relying upon spoken words as the foundation of a cause of action based on s 52 of the Trade Practices Act 1974 (Cth) (or s 42 of the Fair Trading Act ), in the absence of some reliable contemporaneous record or other satisfactory corroboration."
29 Though those words were uttered in relation to a misleading conduct case, they have general application. Indeed, the present case is a case of misleading conduct though it was not pleaded as such. Here, not only was the plaintiff relying on a conversation for which there was no support in contemporaneous records and no corroboration (since, though the plaintiff's brother-in-law was present in the shop at the time, he said he was too far away to hear the conversation), but the plaintiff was contending for a conversation, the inherent unlikelihood of which was high. In addition, the risks of misunderstanding alluded to by McClelland J were doubtless increased by the plaintiff's lack of skill in speaking English. Parts of his evidence were given through an interpreter and the parts which were not were not of high linguistic quality.
30 In my opinion, it cannot be said that the plaintiff has demonstrated error in the trial judge's failure to be satisfied that the conversation took place. As the plaintiff submitted, whether uncontradicted evidence should be accepted depends on all the circumstances, including its inherent probability and the possibility of calling evidence in reply. It was possible but it was not inherently probable. The plaintiff submitted that there was no finding that it was inherently improbable, however the trial judge's statement that the alleged advice was "extraordinary" amounts to the same thing.
31 Further, the failure of the plaintiff to make speedy complaint was, at least taken with other factors, capable of weakening confidence in the vital element of the plaintiff's case. The plaintiff's contention that his failure to confront the defendant or identify the particular employee of the defendant lacked significance because if it had had significance, persons in the position of the plaintiff would invariably fail is invalid. That factor taken with other factors is capable of supporting the trial judge's conclusion in the present case. It might not in other cases, and it might not if it stood alone. In oral argument, it was pointed out on behalf of the plaintiff that after the accident he was in hospital for some time. It was also pointed out that any confrontation might have been less likely once legal advice had been sought. It was submitted that the plaintiff was of little commercial sophistication and did not have a confident command of the English language. In summary, it was submitted that to hold against the plaintiff the fact that he did not confront the defendant or its employees was an inappropriate mode of analysis. As indicated earlier, while standing alone it would not be sufficient to justify the trial judge's reasoning, it cannot be an irrelevant mode of analysis.
35 The plaintiff's complaint that the defendant should have called each of the eleven employees who appeared in court to deny having given the plaintiff the alleged advice is invalid. The plaintiff himself denied that any of them had advised him in the terms complained of. The defendant, on the strength of evidence which the trial judge accepted and which the plaintiff did not claim to have been wrongly accepted, found that there was no other relevant employee. It follows that there was no other member of staff on the plaintiff's own evidence who could have given relevant evidence. Those circumstances meant that Jones v Dunkel (1959) 101 CLR 298 was inapplicable.
36 In Payne v Parker [1976] 1 NSWLR 191 at 201-202, Glass JA said:
"Whether the principle can or should be applied depends upon whether the conditions for its operation exist. These conditions are three in number: (a) the missing witness would be expected to be called by one party rather than the other, (b) his evidence would elucidate a particular matter, (c) his absence is unexplained.
...
According to Wigmore , par 285, the second condition is fulfilled where the party or his opponent claims that the facts would thereby be elucidated. Under other formulations, the condition is made out when the witness is presumably able to put a true complexion on the facts: Jones v Dunkel [(1959) 101 CLR 298 at 308], might have proved the contrary: ibid [(1959) 101 CLR 298 at 312]; would have a close knowledge of the facts: O'Donnell v Reichard [[1975] VR 916 at 921], or where it appears that he had knowledge: Nuhic v Rail & Road Excavations [[1972] 1 NSWLR 204 at 211]. I would think it insufficient to meet the requirements of principle that one party merely claims that the missing witness has knowledge, or that, upon the evidence, he may have knowledge. Unless, upon the evidence, the tribunal of fact is entitled to conclude that he probably would have knowledge, there would seem to be no basis for any adverse deduction from the failure to call him."
Here, the only relevant witnesses to be called were those who, according to the plaintiff, did not speak to him. Their evidence would not have "elucidated" the facts beyond the extent to which the plaintiff had done so. The employees of the defendant who were not called are people whom the plaintiff "merely claims" to have material knowledge. The trial judge concluded that they probably would not have material knowledge. Hence there is no room for Jones v Dunkel to operate.
38 The truth is that the plaintiff's denials of having been served by the eleven employees and the trial judge's acceptance of the proposition that there were no other employees were fatal to the reliability of the plaintiff's account and the trial judge's statement that he was not satisfied that the relevant advice had been given may have been a polite way of cloaking a conclusion implicit in his reasoning that in fact the advice was not given.
39 In oral argument, it was pointed out on behalf of the plaintiff that the identification parade involved an attempt to identify a person whom the plaintiff had only ever seen once. A positive claim of a successful identification might have excited disbelief. Indeed, it was submitted that it might be enormously damaging for the plaintiff to have made such a claim. It was also submitted that when each answer to a series of questions in the form, "The gentleman who has answered the name of Stephen Butler, is he the man who gave you advice", was "no", the true meaning of the evidence is that the plaintiff was simply saying "I am not prepared to put my oath positively to the proposition that he is the man who gave the advice but he could have been." It was also submitted that there was no evidence and there should have been that it was not the practice of employees of the defendant to give advice of the character complained of.
42 I would reject these arguments. The difficulty of identification after one encounter is no doubt a real difficulty but it was inherent in the case which the plaintiff was bringing. Once the plaintiff had denied that the persons in court had served him in the shop, there ceased to be any point in calling them. Whatever the plaintiff's difficulties with English, on the face of the cross-examination as recorded, to say "no" does not mean "I'm not sure". If that was what the plaintiff had intended, the matter could have been clarified in re-examination but there was no re-examination on that point.
43 A further submission advanced orally concerned the following passage in the reasons for judgement:
"The procuring of these persons to this court from Narellan for the identification parade must have been enormously disruptive of the defendant's enterprise and given the circumstances, it can be seen as a forensic exercise in fairness to the plaintiff that led the plaintiff's case nowhere."
44 It was submitted on behalf of the plaintiff that it was wrong for the trial judge "to visit upon the plaintiff's head" the inconvenience to the defendant of having brought those employees to the court and that the passage just set out was a veiled criticism of the plaintiff. It was further submitted that the defendant could have had photographs taken of the relevant employees and had them brought to court for the consideration of the plaintiff. Finally, it was submitted that it was wrong to describe what happened as a forensic exercise carried out in fairness to the plaintiff.
45 First, it seems to me that the trial judge was not criticising the plaintiff for the fact that the identification parade was held; it was not the plaintiff who had asked for it.
46 Secondly, whether or not the identification parade was a forensic exercise being carried out in fairness to the plaintiff does not matter. Even if the trial judge intended to say that, or even if it was a flaw in his approach to say that, it is not a flaw which is decisive and certainly not one which would justify a new trial. The Court is not able to order a new trial unless of opinion that some substantial wrong or miscarriage has been occasioned by the ground of appeal which succeeds: Supreme Court Rules Pt 51 r 23(1)(d).
47 The next matter dealt with in oral argument related to the trial judge's treatment of the plaintiff's evidence about flange changing, which was quoted above. The trial judge said that the plaintiff's evidence was "far from convincing". If the trial judge was intending to reject the plaintiff's evidence on that subject, it was capable of having an impact on his credibility on other subjects and to that extent I would reject the plaintiff's oral argument, which was that doubts about the plaintiff's evidence in relation to the changing of flanges could not rationally affect his reliability on whether the conversation occurred. In the course of oral argument, various possibilities were floated between the bar table and the Court as to the significance of the flange evidence. Even if the trial judge committed some error in relation to the flange evidence or even if there is some obscurity in his reasoning about it, it is not sufficiently decisive in his reasoning to justify a new trial.
49 A further argument advanced on behalf of the plaintiff orally related to the credibility of the plaintiff's wife, brother-in-law and cousin in relation to issues relating to what happened to the purchase docket, what happened to the grinder and what happened to the disk fragments from the disk which had shattered and injured the plaintiff. The submission advanced on behalf of the plaintiff was that if there were difficulties with the particular aspects of the evidence of those witnesses, they did not flow on to justify a rejection of the plaintiff's evidence. A related criticism was that insufficient reasoning was exposed to justify the criticisms made by the trial judge of those witnesses. As to that latter criticism, in my opinion there was sufficient reasoning, brief though it was. The trial judge indicated that there were contradictions between the evidence of the witnesses (as there were) and indicated other weaknesses in it.
50 It is not clear whether the trial judge intended his criticisms of those witnesses to flow on to his evaluation of the plaintiff. There was unquestionably an important relationship between the plaintiff's evidence and their evidence. Some of the difficulties in the plaintiff's case were that there was no corroboration for the vital conversation, that there was no documentary proof of purchase from the defendant and that the absence of the grinder meant that it was not possible to test those parts of the plaintiff's testimony that were related to the grinder.
51 The calling of those witnesses was a decision taken by the plaintiff's advisers in order to explain the lack of some of those vital ingredients. The task committed to those witnesses was a task which they failed satisfactorily to perform. To the extent that the trial judge took this into account in rejecting the plaintiff's case as a whole he was entitled to. If on the narrower question of the plaintiff's personal credibility the trial judge is said wrongly to have used the evidence of the others to reject the plaintiff's evidence, the answer is that the trial judge did not reject the plaintiff's evidence but merely found himself unable either to accept or to reject it. In coming to that conclusion, the trial judge was entitled to take into account the evidence of the other witnesses called on behalf of the plaintiff.
52 The plaintiff's submission that in all the circumstances the trial judge failed to use or palpably misused his advantage in having seen the witnesses is invalid. That contention is not supported by the transcript record of the trial, nor is it supported by the reasons for judgment. Delivered as they were very soon after the trial judge heard the evidence, they reveal a sound grip on the central elements of the evidence. Nor are the particular matters relied on in oral argument concerning the failure to complain, the identification parade and the failure to call employees sufficient to support the argument.
