The question just formulated rests on the assumption that it is to the evidence that, at all events in the first instance, the Court ought, and is entitled, to have recourse, in order to resolve the differences of opinion. I have always taken the view, and shall continue to do so unless directed by a superior court to do otherwise, that the creation of a special division in a court to deal with a particular class of case is not intended to turn the presiding judge into an independent expert in the very field in which testimony will be tendered to him that he will be called on to evaluate. It would never occur to a trial judge who, for example, had heard many cases in which expert medical evidence had been tendered, to choose between the conflicting testimony of two medical witnesses by applying to it his own medical knowledge. That knowledge would, no doubt, have been of inestimable value in understanding the testimony; in suggesting questions; in comparing one set of opinions with another. But it would be quite contrary to principle, I apprehend, for the judge to bring a third set of opinions into the arena, and to supplement or condemn testimony properly adduced before him in reliance on his own theoretical grasp of principles and precepts of medicine. The judge may have proper and rational grounds for preferring one expert to another; such grounds are well-known and accepted. He may, by a consideration of the whole of the evidence, expert and non-expert, be able to conclude that one opinion is more likely to be sound than another or others, even though both or all opinions are given by men of integrity, learning and skill, and are supported, within self-ordained limits, by impeccable reasoning. He may, because he has been persuaded by the evidence of one expert, find that there is a fatal flaw in the reasoning of another. It may appear that, having regard to the whole of the evidence, certain factual assumptions, and hence the opinions based on those assumptions, are not well founded. But the judge cannot arrogate to himself the role of an expert who is, in any respect, primus inter pares. In the Land and Valuation Court I seek to be informed and, as best I can, to evaluate; I do not sit to use such acquired knowledge of valuation principles as I have acquired in order to confirm or to condemn. I must act on the evidence, and if any of it is, in any way, defective, incomplete or irreconcilable then I must make such use as I can of whatever other evidentiary material is available to correct, complete or reconcile."
