5. I think that the conclusion reached by the majority of the Full Court is supported by two decisions in this Court: Kroehn v. Kroehn [1912] HCA 45; (1912) 15 CLR 137 and Smith v. Madden [1946] HCA 19; (1946) 73 CLR 129 . In the latter case Dixon J. (as he then was) said (1946) 73 CLR, at p 132 : "I think that in this Court taxing officers ought not to treat the briefing of two counsel upon a trial as exceptional and as requiring something special in the case to warrant it, but, on the contrary, should treat it as usual and proper unless it happens that the proceedings are simple and not heavy and involve no question of consequence, a thing which, of course, may quite well happen, particularly when the jurisdiction depends, as here, on diversity of residence: See Porter and Wortham, Guide to Costs, 13th ed., pp. 902, 903; Halsbury's Laws of England, 2nd ed., vol. 2, p. 551; and per Madden C.J., Ward v. Roberts & Co. (1897) 23 VLR 182, at p 185 ." It should be noticed that his Honour did not merely say that a case which is not simple or not heavy or involves no question of consequence does not warrant two counsel. These characteristics are stated cumulatively. Where a case is simple and not heavy and involves no question of consequence it is not usual or proper to treat it as warranting two counsel even though the court is the High Court or a State Supreme Court. It could not be anticipated that the present case would be heavy but to attain justice for the plaintiff substantial work had to be done. The proper protection of the plaintiff was likely to demand of counsel more than asking the witnesses simple questions and addressing the jury on readily understood facts. Winneke C.J. made some observations which I think ought to be quoted because, in my view, they demonstrate that the case is of the kind in which it is usual and proper under r. 27 to brief two counsel. His Honour said: "In determining the matter for itself, I think the Court must have regard to the situation facing the plaintiff and his advisers at the time when the decision to brief senior counsel was taken, and to treat the engagement of such counsel as a reasonable and proper precaution, and not due to over-caution, if at that time the action could fairly be regarded as one of real substance. This approach, in my opinion, is justified and required by the reasoning of Dixon C.J. in Smith v. Madden [1946] HCA 19; (1946) 73 CLR 129 , of Lowe J. in Preston v. Preston (1936) ALR 104 , and of Mann C.J. in Freeman v. Freeman (1939) ALR 483 , with which, if I may respectfully say so. I am in full agreement. Approaching the matter in that way, the decision to engage senior counsel in the present case must be viewed in the light of what appear to me to be several important considerations. It had been ascertained that the injuries suffered by the plaintiff were much more serious than was supposed at the time the proceedings were commenced, and by its transfer to the Supreme Court the nature of the action had, notwithstanding the admission of liability, undergone a substantial change. It had become apparent from the reports obtained from the plaintiff's specialists that he was likely to be confronted with an ultimate permanent disability of a substantial nature, the seriousness of which lay in the onset of osteo-arthritis in the hip, with a distinct possibility in the expressed view of one of those specialists of that disease progressing over a period of ten to fifteen years to a degree that would require an arthrodesis. The plaintiff, presenting the appearance of a young and healthy man who had returned to hard labouring work and active participation in vigorous sport, would be faced with the difficulty of inducing a jury to appreciate the full significance of an injury which would only manifest its seriousness in the future, and progressively over a lengthy period of time. In this connexion it is material to say that his appearance before the jury, would be likely to seem consistent notwithstanding the lapse of three years since the occurrence of the accident, with the excellent result mentioned in the hospital report. The sum involved for the plaintiff was likely to be substantially influenced by the view taken by the jury of the degree to which, and the time within which, the osteo-arthritis would probably develop in the future, and as the plaintiff had been examined by two specialists on behalf of the defendants the possibility had to be faced of a sharp conflict of expert opinion on these vital issues of the case. If such conflict occurred, cross-examination of the opposing experts and ultimate presentation of the plaintiff's case to the jury, could have a very material bearing on the amount of the verdict likely to be obtained by him. The case was one in which, it seems to me, the plaintiff and his advisers were faced with a wide margin between possible minimum and maximum verdicts. The cumulative effect of the above-mentioned considerations, viewed as I think it should be in prospect and not in retrospect, was to present the plaintiff and his advisers with substantial difficulties which, in the future conduct of the litigation, could have a marked bearing upon the amount he was likely to recover, and accordingly upon his comfort and security in later life. In my opinion those considerations justify the action in being regarded as one of importance to the parties and of real substance." (at p485)
