15 In a case such as the present, the giving of reasons for arriving at the claimant's damages is generally "an incident of the judicial process" (Housing Commission of New South Wales v Tatmar Pastoral Co Pty Ltd (1983) 3 NSWLR 378 at 386; Public Service Board of New South Wales v Osmond (1986) 159 CLR 656 at 667). What are sufficient reasons depends on why the reasons are required and the particular circumstances, but important functions of the giving of reasons are to enable the parties to know why the damages have been assessed in the particular amount and to enable a dissatisfied party to exercise a right of appeal. Exercise of a right of appeal in relation to assessment of damages will be impeded if it is not known why the judge arrived at the particular amount - how can it be said whether the judge was right or wrong?
16 It is not necessary for the reasons to be lengthy or elaborate, or for every fact leading or relevant to the ultimate decision or the detailed chain of reasoning to be set out (Soulemezis v Dudley (Holdings) Pty Ltd (1987) 10 NSLWR 247 at 271, 280). Nor is it necessary for every matter raised in the proceedings to be dealt with (Kiama Constructions Pty Ltd v Davey (1986) 40 NSWLR 639 at 647).
17 But it is necessary that the reasons show that attention has been given to the evidence critical to the issues in the case and that the basis of critical findings be apparent (Soulemezis v Dudley (Holdings) Pty Ltd at 281; Mifsud v Campbell (1991) 21 NSWLR 725 at 728). The "broad outline and constituent facts on which [the judge] has acted" should be apparent (Soulemezis v Dudley (Holdings) Pty Ltd at 273 per Mahoney JA), or the "essential ground or grounds on which the decision rests should be articulated", including why one conclusion rather than another is to be preferred (Soulemezis v Dudley (Holdings) Pty Ltd at 280 per McHugh JA). As was said by Samuels JA in Strbak v Newton (NSWCA, 18 July 1989, unreported) -
" … It is going too far to suggest that in every case a judge must submit the material before him or her to the most meticulous analysis and carry into judgment a detailed exposition of every aspect of the evidence and the arguments. What is necessary, it seems to me, is a basic explanation of the fundamental reasons which led the judge to his conclusion. There is no requirement, however, that the reasons must incorporate an extended intellectual dissertation upon the chain of reasoning which authorises the judgment which is given."
18 The ability effectively to exercise a right of appeal guides, and sets a minimum standard for, the sufficiency of reasons (Soulemezis v Dudley (Holdings) Pty Ltd at 280-1), always with regard to the particular circumstances.
19 In considering the circumstances of the present case, and applying the foregoing principles, it is necessary to bear in mind the manner in which the trial before Hughes ADCJ was conducted. As is not uncommon, his Honour had an abundance of medical and other reports, but with the one exception no oral evidence from the authors of the reports to assist him in evaluating them and reconciling or choosing between them. The realities of much litigation of the present kind have to be acknowledged, and they do not make the judge's task any easier. In such circumstances, a judge's findings may be greatly dependent on his assessment of the claimant as an accurate historian of the claimant's injuries and disabilities, and the judge's preference for one medical or occupational opinion rather than another or others may be difficult to displace on appeal. But it is still necessary for the judge to explain, conformably with the principles described above, why the particular medical or occupational opinion is preferred, and that will normally involve at least some analysis of the divergent opinions. If, as may often be the case, the judge's assessment of the reliability of the claimant is significant to the preference, it may be all the more important that the judge so indicate, and that the explanation extend to why the particular view is taken of the claimant's evidence.
20 Regrettably, and with full appreciation of the difficulty in which his Honour was placed by the manner in which the trial was conducted, I do not think he gave adequate reasons for his findings as to the appellant's injuries and disabilities and the assessment of her damages. A number of matters contribute to their deficiency.
21 While stating that he had carefully read all the medical evidence, which he described as conflicting greatly, his Honour neither described the respects in which there were different opinions nor, beyond the bald acceptance of Dr Potter, why he found that the only complaints attributable to the accident related to a closed head injury (no longer symptomatic) and the left knee. The appellant's evidence put forward a great many other complaints, broadly conformably with the particulars. It seems (although it is not clear) that his Honour accepted that the appellant had disabilities going beyond the complaints he upheld, but regarded them as a result of "various other difficulties that this plaintiff has had". The other difficulties which he had in mind may have been the fracture, thyroid deficiency and hormone replacement therapy, but preference for those difficulties as the reason for the other complaints is not explained.
22 Even the finding based on acceptance of Dr Potter was qualified. The finding as to some of the multiple complaints but not others was "by and large", and reference to the passage from Dr Potter's report took the reader only to another unspecific selection of integers of what was described only as a significant injury. This exacerbates the unsatisfactory features identified in the preceding paragraph.
23 Reference to Dr Potter's report shows that he accepted that there was a fractured left knee, a head injury, a neck injury, and facial lacerations, and that there was a component of depression. Dr Potter also found symptomatology relating to both knees. He referred to "behavioural issues and degenerative issues" as "factors … independent of the mva", and to pains "while mobilising". If attention be confined to Dr Potter's reports (there were two), they supported greater injury and disability attributable to the accident than stated by his Honour, and were arguably consistent with disabilities not directly due to the accident but causally related to it. There was abundant evidence, from the appellant and from other doctors, of continuing cervical problems and of effects upon the right knee and the shoulders, arms and hands of strain flowing from the injured left knee and the use of crutches. None of this was dealt with by his Honour.
24 Brain damage was rejected, but the appellant's evidence and the reports (including Dr Potter's reference to a component of depression and a report of Dr James Maguire, a psychiatrist who assessed the appellant on behalf of the respondent) gave considerable support for emotional disturbance causally related to the accident. Dr Middleton referred to "emotional/psychological trauma resulting from the initial accident and [the appellant's] ongoing pains and disabilities". This also was not dealt with by his Honour.
25 The denial of damages for home care services was because of acceptance of Dr Jones' opinion that the appellant was "independent of personal care and most activities of daily living …". This left some activities of daily living possibly affected by the appellant's disabilities, and there was much evidence from the appellant and her husband, with support from the opinion of Dr Middleton, which if accepted demonstrated the need for assistance during recovery, some continuing need for assistance, and a likelihood of increased need for assistance in the future. His Honour did not express reservations as to the credibility of the appellant or her husband. The allowance for future medical expenses would seem to accept deterioration in the appellant's condition with a need for assistance in the future. The one-sentence treatment of the matter by his Honour, with respect, was less than sufficient attention to a significant element in the appellant's claim.
26 In my opinion these matters are enough to demonstrate, without going further, the deficiency in his Honour's reasons. While detailed exposition was not necessary, in order that he assess the appellant's damages his Honour had to find with clarity the injuries she had suffered in the accident and the disabilities causally related to the accident; where there was conflict, it had to be apparent that he had paid regard to the full extent of the appellant's claims and had made his finding on rational grounds explaining his resolution of the conflict. In the circumstances of this case, and particularly because he did not express reservations as to the credibility of the appellant or her husband, it was not sufficient to state acceptance of the opinions of Dr Potter and Dr Jones without noticing the evidence of the appellant and her husband and the conflicting opinions and, however, succinctly, explaining his preference. Lesser difficulties in the reasons aside, they did not do this.
27 It was common ground that, if the appeal was allowed, the Court could not reassess the appellant's damages. I propose that the appeal be allowed with costs, that the judgment for $318,776.00 be set aside, that the proceedings be remitted to the District Court for rehearing limited to assessment of damages, and that the respondent have a certificate under the Suitors Fund Act if qualified. The order made below for the costs of the trial should stand.
