VAN DEN HEUVEL v TUCKER No. SCCIV-00-1212 [2003] SASC 110 - SASC 2003 case summary — Zoe

[159]

As this Court there said, that approach was "not only sound in law, but beneficial in ... operation.

After Warren v Coombes, a series of cases was decided in which this Court reiterated its earlier statements concerning the need for appellate respect for the advantages of trial judges, and especially where their decisions might be affected by their impression about the credibility of witnesses whom the trial judge sees but the appellate court does not. Three important decisions in this regard were Jones v Hyde, Abalos v Australian Postal Commission and Devries v Australian National Railways Commission. This trilogy of cases did not constitute a departure from established doctrine. The decisions were simply a reminder of the limits under which appellate judges typically operate when compared with trial judges.

The continuing application of the corrective expressed in the trilogy of cases was not questioned in this appeal. The cases mentioned remain the instruction of this Court to appellate decision-making throughout Australia. However, that instruction did not, and could not, derogate from the obligation of courts of appeal, in accordance with legislation such as the Supreme Court Act applicable in this case, to perform the appellate function as established by Parliament. Such courts must conduct the appeal by way of rehearing. If, making proper allowance for the advantages of the trial judge, they conclude that an error has been shown, they are authorised, and obliged, to discharge their appellate duties in accordance with the statute.

Over more than a century, this Court, and courts like it, have given instruction on how to resolve the dichotomy between the foregoing appellate obligations and appellate restraint. From time to time, by reference to considerations particular to each case, different emphasis appears in such reasons. However, the mere fact that a trial judge necessarily reached a conclusion favouring the witnesses of one party over those of another does not, and cannot, prevent the performance by a court of appeal of the functions imposed on it by statute. In particular cases incontrovertible facts or uncontested testimony will demonstrate that the trial judge's conclusions are erroneous, even when they appear to be, or are stated to be, based on credibility findings.

One of the topics canvassed during the argument was one that frequently arises in these cases, namely the propriety of a witness, particularly an expert witness, giving evidence in terms of the ultimate issue to be decided by the court. I mentioned this subject incidentally in Cavanett v Chambers ([1968] SASR 97), and I do not see any reason to depart from the views I expressed there. Such evidence is probably still strictly inadmissible (Director of Public Prosecutions v A & BC Chewing Gum Ltd [1967] 2 All ER 504) per Lord Parker CJ at p 506), though it is, in fact, often admitted without objection and there may be cases where it must be admitted, such as evidence of insanity within the M'Naghten Rules, because it is impossible for the opinion of the expert to be conveyed in any other form. But in my view it should be allowed only where absolutely necessary, and in cases like this it is not absolutely necessary. In this case the choice of the word 'appreciable' was the choice of the witness, not the choice of counsel. Presumably he chose it because he knew that it appeared in the statute, but it appeared subsequently from the cross-examination that he did not attach to it, or at least that he may not have attached to it, the meaning which this Court has held that it bears. That illustrates the danger of the practice. I respectfully but emphatically agree with the remarks of Turner J, in his dissenting judgment in Blackie v Police ([1966] NZLR 910, at pp 919-920):-

I approach the problem with an acute sensibility that there is always danger in allowing an expert witness, or indeed any witness, to answer the very question which the Court is called upon to decide. Once this is done and an answer given which is accepted by the Court, the chances of success on an appeal on fact are slight indeed, since there is direct and acceptable evidence on the very point at issue. The consequences of the answer may therefore be nothing less than disastrous from the point of view of the defendant. The only justification which can be advanced for allowing the question must be the impossibility or extreme difficulty of arriving at the truth in any other way; and even in such cases it is indispensable that there must be both a high degree of skill and a complete impartiality in the witness called.

Three or four decades ago it was, speaking generally, reasonable to expect a driver to deal with the exigencies of motor and pedestrian traffic as they presented themselves from moment to moment, but he was not asked to look very far ahead and to seek out possible trouble. Today, I think that the situation has changed fundamentally. Population has increased; a high proportion of families have at least one car and not infrequently two; accidents are numerous; and death on the roads has become tragically familiar. In these circumstances, I think courts, when performing the role of a jury, are entitled, indeed bound, to require of motorists a measure of what is sometimes called defensive driving, or a look out that not only sees immediate, or immediately developing, danger, but looks well ahead and searches for potential danger. Nowadays, for example, a young child on the footpath is not just a person so many feet away, but is a human being that may suddenly present himself in your path; a green light is not just an authority to spring off the mark without further thought, but is an invitation to look to right and left before moving off in case someone is trying unsuccessfully to beat the lights; a bus is not just a stationary vehicle, but represents cover from which, at any time, a pedestrian may emerge; a car with its turning flicker on may not be going to turn, but may have left his flicker on inadvertently; the car that you are following is to be kept a respectable distance in front of you because, at any moment, the driver may stop or slow down virtually without notice; a crest in the road is not just another part of the road, but is a danger point where a motorist, coming in the opposite direction, may well seek to pass on the rise. All these situations, and countless others besides, call for consideration by the reasonable driver because experience has repeatedly shown that perils on the road, as time goes by, seem to be giving less and less warning of their emergence. Of course, what I have said has its corollaries for other road users, but because of the marked increase in the power, weight and speed of today's vehicles, as compared with those of the immediate post-war period, the implications for the drivers of motor vehicles are, in my view, stronger. The courts have, from time to time, spoken of the need to guard against human follies, but, in my opinion, there is a need for courts to emphasize that the guarding referred to includes an ever-present attempt to foresee dangers well ahead of the immediate driving situation.

The true advantages in fact-finding which the trial judge enjoys include the fact that the judge hears the evidence in its entirety whereas the appellate court is typically taken to selected passages, chosen by the parties so as to advance their respective arguments. The trial judge hears and sees all of the evidence. The evidence is generally presented in a reasonably logical context. It unfolds, usually with a measure of chronological order, as it is given in testimony or tendered in documentary or electronic form. During the trial and adjournments, the judge has the opportunity to reflect on the evidence and to weigh particular elements against the rest of the evidence whilst the latter is still fresh in mind. A busy appellate court may not have the time or opportunity to read the entire transcript and all of the exhibits. As it seems to me, these are the real reasons for caution on the part of an appellate court where it inclines to conclusions on factual matters different from those reached by the trial judge. These considerations acquire added force where, as in the present case, the trial was a very long one, the exhibits are most numerous, the issues are multiple and the oral and written submissions were detailed and protracted. In such cases, the reasons given by the trial judge, however conscientious he or she may be, may omit attention to peripheral issues. They are designed to explain conclusions to which the judge has been driven by the overall impressions and considerations, some of which may, quite properly, not be expressly specified.

All of the foregoing considerations leave to be weighed, in some cases at least, the impression which the trial judge holds of a particular witness, perhaps influenced by the witness's demeanour and the kinds of considerations commonly referred to such as hesitation or displays of partisanship not readily conveyed, or conveyed at all, by the printed record. One can hold different views about whether such considerations should intrude in the assessment of qualified expert witnesses. One can strive to minimise resort to such considerations in the case of lay witnesses, out of recognition of the fallibility of human assessment of credibility from appearances. But because trials remain public procedures for the resolution of disputes, it is inescapable that, in some cases at least, credibility assessments will be required where there is no documentary, electronic or other incontrovertible evidence to resolve the conflict presented for decision. In such cases it will remain the fact that, try as it might, the appellate court cannot procure from the printed record exactly the same materials on which to base the judicial decision as the trial judge had.

This conclusion may, as I think, be true of a relatively limited class of case: basically those where the decision depends upon resolving a clash of critical oral testimony, oath against oath. But in such cases, because the appellate court cannot, in presently available records, recapture all of the information properly used to assist the trial judge's decision, the old strictures about that judge's advantage remain as relevant today as they were when first written more than a century ago. In such cases, the appellate court's rehearing must be conducted within a constraint which is set by the somewhat more restricted data available to it. This limitation is not confined to Anglo-Australian law. It is recognised in other countries of the common law and doubtless beyond.

One means of alleviating the burden cast by law on a plaintiff to establish a causal relationship between the breach and the damage concerns the evidentiary onus. Australian law has not embraced the theory that the legal onus of proof shifts during a trial. Nevertheless, the realistic appreciation of the imprecision and uncertainty of causation in many cases - including those involving alleged medical negligence - has driven courts in this country, as in England, to accept that the evidentiary onus may shift during the hearing. Once a plaintiff demonstrates that a breach of duty has occurred which is closely followed by damage, a prima facie causal connection will have been established. It is then for the defendant to show, by evidence and argument, that the patient should not recover damages. In McGhee v National Coal Board, a Scottish appeal, Lord Wilberforce explained why this was so. Although Lord Wilberforce's statement in McGhee has proved controversial in England, it has received support in this Court. Its principle has also been accepted by international experts such as Professor Giesen. I find Lord Wilberforce's exposition compelling:

'T]he question remains whether a pursuer must necessarily fail if, after he has shown a breach of duty, involving an increase of risk of disease, he cannot positively prove that this increase of risk caused or materially contributed to the disease while his employers cannot positively prove the contrary. In this intermediate case there is an appearance of logic in the view that the pursuer, on whom the onus lies, should fail - a logic which dictated the judgments below. The question is whether we should be satisfied, in factual situations like the present, with this logical approach. In my opinion, there are further considerations of importance. First, it is a sound principle that where a person has, by breach of a duty of care, created a risk, and injury occurs within the area of that risk, the loss should be borne by him unless he shows that it had some other cause. Secondly, from the evidential point of view, one may ask, why should a man who is able to show that his employer should have taken certain precautions, because without them there is a risk, or an added risk, of injury or disease, and who in fact sustains exactly that injury or disease, have to assume the burden of proving more: namely, that it was the addition to the risk, caused by the breach of duty, which caused or materially contributed to the injury? In many cases ... this is impossible to prove, just because honest medical opinion cannot segregate the causes of an illness between compound causes. And if one asks which of the parties, the workman or the employers, should suffer from this inherent evidential difficulty, the answer as a matter of policy or justice should be that it is the creator of the risk who, ex hypothesi must be taken to have foreseen the possibility of damage, who should bear its consequences.'
