As this finding of her Honour is a finding based at least in part on the credibility of a witness, the constraints on challenges to such findings identified by the High Court need to be applied: "[t]he finding must stand unless it can be shown that the trial judge has failed to use or has palpably misused his or her advantage or has acted on evidence which was inconsistent with facts incontrovertibly established by the evidence or was glaringly improbable" ( Devries v Australian National Railways Commission [1993] HCA 78; (1993) 177 CLR 472 at 479, citations omitted; affirmed in Fox v Percy [2003] HCA 22; (2003) 214 CLR 118 at [26-7]).
15 On appeal, the appellant complained in relation to this finding that "[t]he trial judge failed to provide any analysis of the evidence or address any part of the Appellant's case" (Orange Appeal Book 9V). A number of matters were then referred to by the appellant. I will come to these shortly.
16 Before doing so, I point out that it is not incumbent upon a trial judge to refer to all of the evidence before him or her. That would impose an unreasonable and unnecessary burden. As Meagher JA put it in Beale v GIO of NSW (1997) 48 NSWLR 430:
"[W]here certain evidence is important or critical to the proper determination of the matter and it is not referred to by the trial judge, an appellate court may infer that the trial judge overlooked the evidence or failed to give consideration to it …" (at 443; see also Young v Cesta-Incani [2007] NSWCA 229 at [56].
17 There was of course a good deal of evidence to which her Honour did not refer but the question which needs to be addressed is whether there was anything "important or critical" to which she should have referred, but did not refer. If there was, it may indicate that there was an error in her Honour's process of fact finding (see Waterways Authority v Fitzgibbon [2005] HCA 57; (2005) 79 ALJR 1816 at [130] per Hayne J), such that her Honour's conclusions may be amenable to challenge consistently with the principles stated in Devries and quoted above.
18 The first matter referred to by the appellant was evidence given by the respondent and his wife concerning work performed by the respondent at his wife's business. That evidence was not, by reason of any conflict between the respondent's evidence and that of his wife or otherwise, "critical or important". There was nothing in it which in my view needed to be referred to by her Honour.
19 The appellant then complained of deficiencies in her Honour's treatment of the evidence as to the pre-accident condition of the respondent's low back. It made reference to the evidence of Dr Lee, the cross-examination of Dr Evans, worker's compensation claim forms which the respondent completed, the evidence "contained within any of the Exhibits" and the evidence of Dr Smith (Orange Appeal Book 10J-P).
20 As to these matters, evidence of Dr Lee as to the respondent's ongoing incapacity was sufficiently referred to by her Honour (Red Appeal Book 19D) and there was in fact no cross-examination of Dr Evans. Further, none of the evidence comprising the claim forms or the other Exhibits to which the Court was taken on the appeal were in my view of a sufficiently significant nature to require mention by her Honour.
21 The remaining evidence to which the appellant referred was that of Dr Smith, who was called as a witness by the appellant. He expressed the view that the respondent was "manufacturing his illness". Her Honour referred to that evidence and gave reasons for rejecting it (Red Appeal Book 20T-21G). As is apparent from those reasons, her Honour's conclusion as to Dr Smith's evidence was very much bound up with the view that she took about the respondent's evidence. Once her Honour had concluded that the respondent had ongoing pain in his low back and left leg and that his perception of that pain had been heightened by a depressive condition which he had (Red Appeal Book 22F), it followed that the proposition propounded by Dr Smith that the respondent was manufacturing his illness was liable to be rejected, as in fact occurred. Her Honour's conclusion concerning Dr Smith being dependent to a significant extent upon the credit based finding in relation to the respondent, I see no basis upon which the conclusion is open to attack consistently with the Devries' principles.
22 The appellant also complained that the primary judge did not refer to numerous occasions upon which the respondent gave evidence to the effect that he could not remember certain matters about which he was asked. Those answers did not in my view reflect adversely on the credit of the respondent and it was certainly open to her Honour to take that view, as she apparently did. There was nothing about the answers which characterised them as "important or critical" matters which needed to be the subject of reference by her Honour.
23 Finally under this heading, the appellant criticised her Honour's statement that the evidence of the respondent "was not significantly challenged in any material respect" (see the passage from the judgment quoted in [6] above). This statement by her Honour needs to be understood in the context in which it appears, namely, at the end of a paragraph which she commenced by referring to the submission of the appellant that the respondent "was not a reliable witness" and which identified matters relied upon by the appellant. Understood in its context, her Honour's statement is an expression of a view that the matters relied upon by the appellant to challenge the respondent's credit were not significant matters. That being her Honour's view, and it being a view that I share, there is no justification for a complaint that she did not descend to any greater detail in her judgment.
24 Support for her Honour's view is to be found in a reading of the transcript of the appellant's oral address at the trial. Counsel for the appellant described as the "hub" of the appellant's submissions the proposition that what occurred by reason of the accident was "an aggravation that's lasted for a limited period of time". He said that the respondent's pre-existing back condition would have continued to deteriorate and would have "overtaken" the aggravation caused by the accident (Black Appeal Book 113P-T). This submission did not sit well with the proposition advanced by Dr Smith that the respondent was "manufacturing" his illness. Rather, the submission assumed that the respondent had significant continuing pain but that after a period of "say six months" after the accident that pain was attributable not to the accident but to a progressive deterioration of a pre-existing back condition. Having described the "hub" of his submissions in this way, counsel for the appellant then said that he was going to "address a couple of other issues and then turn to the schedule of damages". He said in this context that "your Honour would have a concern about the evidence of the plaintiff"(Black Appeal Book 113U). Limited matters were then referred to. Her Honour could in these circumstances well be forgiven for not regarding the challenge to the respondent's credit as a major one based on matters of telling significance.
