It is also true that, statute apart, whilst an expert may inform himself in any
way he chooses (including in many cases from sources which are necessarily
hearsay) he may not give hearsay evidence as to details of any transactions not
within his personal knowledge in order to establish such details as matters of fact:
English Exportees (London) Ltd v Eklonwall Ltd [1973] 1 All ER 726. In the
present case, however, there is a statute, to the terms of s38 of which I have
already referred, which largely dispenses with the rules of evidence. Since the
statute permitted the reception into evidence of the respondent's valuer's
evidence as to the sales relied on by him (and, if it matters, that evidence was
given without objection), it can hardly be contended that the evidence was
inadmissible. Indeed, Mr Hamilton QC, senior counsel for the appellant, did not
so contend. Rather, his contention was that his Honour should have placed
minimal reliance on the respondent's valuer's evidence for the reason referred to.
But, once evidence has been properly admitted at a trial, the weight to be
accorded to that evidence is purely a matter for the trial judge; and, more
importantly, a ground of appeal that a trial judge gave inappropriate weight to
particular evidence raises a question of fact, not a question of law: see Azzopardi
v Tasman UEB Industries Ltd (1985) 4 NSWLR 139. These considerations alone
would dispose of the first ground of appeal adversely to the appellant. But even
if they did not exist I would be reluctant to uphold this ground of appeal, because,
as Mr Hall QC, senior counsel for the respondent, pointed out to us, the appellant
had been given notice of the sales relied on by the respondent, and therefore had
ample opportunity to examine, if he wished, the contracts of sale relating to those
sales, and to cross-examine the respondent's valuer about them or even tender
them; but he denied himself the opportunity to utilize this advantage.
