On occasion the ground was no more than that her Honour had erred in making a finding; see for example grounds 3, 4, 5, 6, 51 and 57.
61 Having read the written submissions and listened to the submissions put orally I am satisfied, for reasons I will come to, that the evidence was sufficient for her Honour to conclude that the assaults had occurred on the four occasions she described and in the manner she described. The substance of the appeal is in the area of causation and whether it was open to the trial Judge to conclude that the deep vein thrombosis in the right axillary and sub-clavian veins was caused or exacerbated by all or any of the assaults.
62 The nature of the appeal and particularly the grounds of appeal require reference again to the principle for which Abalos v Australian Postal Commission (1990) 171 CLR 167 stands. In Rosenberg v Percival (2001) 75 ALJR 734 McHugh J, with whom on this point Gummow J agreed (see para 92), said at para 37 and following:
"[37] As Brennan and Gaudron JJ and I said in Devries v Australian National Railways Commission , 'the trial judge had the advantage, which was denied to the judges of the Full Court, of being able to judge the true character and intelligence of the plaintiff' ((1993) 177 CLR 472 at 477). In addition, as I have pointed out above, there were many objective matters that supported the trial judge's findings that the patient would have had the operation even if the risk had been drawn to her attention. None of the matters referred to by Kennedy J pointed so overwhelmingly to the patient not proceeding with the surgery that they negatived the advantage that Gunning DCJ had in seeing and hearing the patient. Even if the matter is looked at on a purely objective basis, the matters against the patient's claim were as weighty as the matters in her favour, perhaps more so. Once it is accepted that the matters in her favour could not overwhelm either the matters against her or the judge's assessment of her character, fortitude and intelligence, the Full Court's opportunity to review the judge's finding on the causation issue was very limited.
[38] Wherever the boundary of review lay, in the circumstances of this case, the Full Court could not set aside the trial judge's findings on the bare ground that he did not give sufficient weight to matters that the judges of the Full Court thought assisted the patient's case. In Devries , Brennan and Gaudron JJ and I also said (at 479):
'More than once in recent years, this Court has pointed out that a finding of fact by a trial judge, based on the credibility of a witness, is not to be set aside because an appellate court thinks that the probabilities of the case are against - even strongly against - that finding of fact. If the trial judge's finding depends to any substantial degree on the credibility of the witness, the finding must stand unless it can be shown that the trial judge 'has failed to use or has palpably misused his advantage' or has acted on evidence which was 'inconsistent with facts incontrovertibly established by the evidence' or which was 'glaringly improbable'. [citations omitted]
[39] To similar effect are remarks of Deane and Dawson JJ in Devries. Their Honours said at 482-3 that, 'consistently with the obligation to make full allowance for the advantage which the trial judge had enjoyed, the Full Court could properly overturn the trial judge's finding only if it was vitiated by some error of principle or mistake or misapprehension of fact or if the effect of the overall evidence was such that it was not reasonably open' to make the finding that he did.
[40] In this case, the trial judge's finding was based on the credibility of the witness and on facts that were not 'inconsistent with facts incontrovertibly established by the evidence' or 'glaringly improbable'. That being so, it is impossible to conclude that he failed to use or has palpably misused 'his advantage' because he did not give to countervailing matters the weight that the Full Court thought they deserved.
[41] One of the consequences of the 'advantage' of seeing and hearing the witnesses is that the trial judge is in a far better position than an appellate court to know what individual weight should be assigned to the various factors - credibility, matters for and matters against - that must be evaluated in making the ultimate findings of fact in the case. Where a finding is based on credibility and other facts support the finding, the case would need to be exceptional before an appellate court could set aside the finding on the ground that, judging by the transcript, the trial judge gave insufficient weight or consideration to other facts and circumstances in the case. The common law tradition is an oral tradition. Trial by transcript can seldom be an adequate representation of an oral trial before a judge or an oral trial before a judge and jury.
[42] No suggestion could reasonably be made that Gunning DCJ acted on an erroneous principle or mistook or misapprehended the facts of the case. Nor was the overall effect of the evidence such that it was not reasonably open to find that the patient would have proceeded with the surgery, if she had been warned of the possibility of a temporomandibular joint disorder."
63 The trial Judge was aware of the seriousness of the respondent's allegation that the appellant had assaulted her on the several occasions referred to. Her Honour referred to Briginshaw v Briginshaw in which at 362-3, Dixon J, after referring to statements that an issue such as fraud must be proved "clearly", "unequivocally", "strictly", or "with certainty", said:
"This does not mean that some standard of persuasion is fixed intermediate between the satisfaction beyond reasonable doubt required upon a criminal inquest and the reasonable satisfaction which in a civil issue may, not must, be based on a preponderance of probability. It means that the nature of the issue necessarily affects the process by which reasonable satisfaction is attained. When, in a civil proceeding, a question arises whether a crime has been committed, the standard of persuasion is, according to the better opinion, the same as upon other civil issues (citations omitted). But, consistently with this opinion, weight is given to the presumption of innocence and exactness of proof is expected."
64 The trial Judge accepted the respondent's evidence about the first assault particularised. Her Honour's finding coincided with the respondent's sworn evidence. The respondent said that the assault occurred in mid-April 1995. The trial Judge said it probably occurred later than that and may have occurred at the end of May or on 4 June 1995. On 4 June as the appellant conceded the respondent telephoned her sister and complained that she had been assaulted. The respondent consulted Dr Soe in relation to itchiness and a rash on her body on 29 May and 1 June 1995. She said she told Dr Soe about a physical assault. Dr Soe's account was that she did mention the appellant's cruelty and controlling behaviour but made no mention of an assault. The trial Judge preferred Dr Soe's account.
65 Her Honour was comfortably satisfied that the respondent and her witnesses were honest and reliable in relation to the critical matters about which they gave evidence and that the appellant and his mother were dishonest. Her Honour recognised that as she presented herself the respondent was a volatile, emotional and somewhat histrionic witness who was at times verbally aggressive and interrupted questions which were put to her. I do not accept that assuming, as is asserted, that the respondent as a witness had a propensity to blame others or was less than reliable in allegations she made against the appellant and other people concerning matters independent of her cause of action, it was not open to the trial Judge to come to the conclusion that she was honest and reliable in relation to critical matters about which she gave evidence or that it was not open to the trial Judge to conclude on the evidence that it would have been very difficult for the respondent to lie in relation to many matters about which she gave evidence or that it was not open to her to come to the conclusion that the appellant was an unimpressive witness because of various matters referred to as occurring during his cross-examination. It was quite open to her Honour to take account of the fact that the appellant gave evidence about matters which were not put in cross-examination to the respondent. As the respondent submitted, what weight her Honour put on the various matters described in the grounds of appeal under the heading "Findings of Credit" was entirely for her.
66 What I have said about the first assault applies to the other three assaults particularised, except that the trial Judge was satisfied they occurred on the dates alleged. The findings were based on the respondent's oral evidence which was accepted. On the evening of 12 June 1995, the day of the second assault particularised, the respondent was admitted to the St George Hospital. A venogram disclosed a thrombosis of the axillary sub-clavian vein. Her Honour noted that the evidence given by the appellant's mother differed from the contents of two Family Court affidavits. She considered that the appellant and his mother fabricated their evidence of arm complaints by the respondent. This finding suggests, though her Honour did not rely on it, that the appellant had something to hide about what happened. The trial Judge accepted the respondent's evidence that she was frightened to disclose the assault at the hospital because of threats made to her by the appellant and through June was too embarrassed to disclose the assault. Her Honour observed that she may well have considered that disclosure would undermine her prospects of preserving the marriage.
67 The evidence of the respondent about the assault on 3 July 1995 is consistent with that given by her father, Mr Pitt, which her Honour accepted. The trial Judge said:
"The plaintiff's parents were both reliable witnesses. I was particularly impressed by the evidence of the plaintiff's father, who was calm, fair and, if anything, understated in his evidence."
68 On 4 July 1995 the respondent told Dr Lines that she had been assaulted by the appellant (this appears in his patient card note of 4 July 1995, Blue AB 155). When the police were called to the matrimonial home at Mortdale the respondent's mother told them that she had just found out that the appellant had been assaulting the respondent. This allegation was made in the appellant's presence and he did not deny it. The appellant's evidence was that when he arrived home there was no mention of domestic violence or assault and he had not heard the respondent's mother speaking to the police about an assault. His allegation that the respondent in the presence of her mother started to do pretend karate fist punches and sternum punches very close to his face in a threatening manner was put neither to the respondent nor to her mother in cross-examination.
69 The fourth assault particularised occurred on 5 July 1995 at a time shortly before or during which the respondent spoke to Pastor Murdoch by telephone. Apart from the time of the conversation the trial Judge accepted the evidence of Pastor Murdoch. As a result of a second conversation with the respondent Pastor Murdoch spoke to the police. This seems to have resulted in a further police attendance.
70 I am satisfied that on the evidence and bearing in mind the seriousness of the allegations the trial Judge was entitled to find that the assaults occurred as the respondent described them. Ample reasons were given for her conclusions which in substance flowed from her hearing the respondent give evidence and believing what she said despite an acknowledgment that in some respects the respondent's presentation and manner were unsatisfactory. The trial Judge was alive to all these matters but they did not individually or together make her Honour's findings glaringly improbable or in any sense inconsistent with facts incontrovertibly established by the evidence. To my mind it was understandable that newly married the respondent did not immediately complain to doctors or to her parents. From 3 July she did complain. I would reject the grounds of appeal relied upon to support the submission that all or any of the findings of physical assault should be overturned.
71 In a case such as the present, where much depends upon the history that a plaintiff gave to treating and other doctors, upon her appearance when she visited them and upon which of differing opinions should be accepted, the trial Judge faces an extremely difficult task in doing justice to the parties on evidence which consists entirely of medical reports without any oral medical evidence. In Ziade v NSW Ministerial Insurance Corporation (Court of Appeal, 26 March 1993, unreported), Handley JA observed that the plaintiff's case had been conducted with an economy of effort not appropriate in a case where serious injuries were alleged and substantial damages claimed. In that case the plaintiff was the only witness called to give oral evidence and on the medical issues the plaintiff's legal advisers contented themselves with tendering a bundle of medical reports. The defendant responded by tendering a further bundle of medical reports. The trial Judge had great reservations about the plaintiff's credit. His Honour accepted the opinion of one of the doctors in one of his reports. Handley JA remarked that it was impossible for the Court on the materials available to it and given his Honour's findings as to the credibility of the plaintiff to disturb his conclusions on the medical evidence. Kirby P, as his Honour then was, said:
"…(as we see in virtually every running list of this kind) cases are increasingly being determined in the way this case had to be determined, namely, by the evaluation of the oral evidence of the plaintiff alone and the attempt by the trial Judge to decide where the truth and justice lay as between the series of conflicting medical reports seen from the perspective of the impression which the plaintiff makes. On the face of things this is an odd way to resolve the differences of conflicting expert opinions."
72 Judge Murrell found that on the occasion of the first assault particularised the appellant hit the respondent in the chest delivering what the respondent referred to as a "sternum hit". He hit her a couple of times that way. On 12 June 1995 he punched her twice in the top front of her right arm connecting through to her chest. By that night a test disclosed a thrombosis of the axillary sub-clavian vein. On 3 July 1995 the appellant punched the respondent three or four times in the right upper arm/shoulder area very hard with a closed fist. On 4 July 1995 he pushed or attempted to push her. On 5 July 1995 he started to hit her in the back of her head, on her right arm, in the shoulder and chest areas, in her stomach and on her legs. The trial Judge found, and on the evidence this seems to be beyond doubt, that the respondent had a predisposition to the development of Padgett Schroeder Syndrome or effort thrombosis of the axillary sub-clavian vein. This conclusion was supported by Professor May's report of 14 November 1996. Professor May went on to say that the diagnosis of the respondent as having a deep vein thrombosis in the right axillary sub-clavian vein could be caused by physical assault in the vicinity of where the blood clot actually formed. The likely effect of a direct assault in the vicinity of the clot would be an extension of the clot embolisation where a portion of the clot breaks free and travels in the direction of the lungs. The respondent had evidence of such an abnormality on physical examination.
73 Dr Endrey-Walder in his report of 19 February 1999 was of opinion that it was difficult to argue that anything short of a direct blow over the vein, well protected behind the clavicle, could conceivably have caused the clotting. He took the view on a history different from the evidence that the respondent gave namely, the respondent's indication to him that the alleged assault was with a closed fist to the lateral aspect of her right arm, that an injury even with a closed fist to that part of the body would not cause a thrombosis in the axillary sub-clavian vein.
74 Neither party saw fit to require any of the medical experts to attend for cross-examination. They were content to leave it to her Honour to decide the case on the written reports. Her Honour accepted the opinion of Professor May which was consistent with that of Dr Endrey-Walder if the blow was a direct blow over the vein. On the evidence her Honour was satisfied that in the assault of 12 June 1995 the appellant did land a direct blow over the vein. This accorded with the respondent's evidence both as to the nature of the blow and as to what was diagnosed when she arrived later that evening at St George Hospital. The trial Judge said:
