(j) The operation of s60 on assumption evidence which is given as the basis for an expert opinion is also a special case. Where such evidence is in the form of a bare statement of facts or where facts are stated as having been provided by some other person or persons, s60 operates to make the account evidence of the truth of the facts so stated. That is not so if the expert says that certain facts are assumed for the purpose of providing the opinion. A disadvantage should not be incurred in legal proceedings by happenstance. If the facts stated are contentious, it will ordinarily be unfair that the opposite party is fixed with assumption evidence as evidence of the truth of the facts stated by reason of those facts having been stated in one form rather than the other.
18 In this case, Mr Prior's hearsay evidence went to the result of his inquiries into how the College had conducted its financial and accounting affairs; the state of its accounts and how a trust account had been operated. In his evidence, Mr Prior did not set out what he had been told, but rather summarised the results of his inquiry. The applicants elected not to call direct evidence about various of the matters dealt with in Mr Prior's evidence. It must follow that in this case, the applicants chose the hearsay form, for the purpose of proving the asserted facts by hearsay evidence.
19 This is an unusual approach, as is observed in Odgers, where it is said at footnote [74] 'as a practical matter, one would expect the persons who made the statements to be called as witnesses'. Here, while Mr Brash and Mrs Brash, for example, were called, it appears that there was a deliberate decision made not to call direct evidence from them about matters relevant to what has to be determined in those proceedings. Rather, in his report, Mr Prior summarised his understanding of what they had told him. The end result would appear to have been a process whereby the applicants determined to engage an expert to inquire into matters relevant to what arises for determination in these proceedings, rather than to have the evidence as to those matters called and tested directly at the hearing, before the Court which has to decide the claims which the applicants seek to advance in the proceedings.
20 This is a very unusual approach in my experience, involving a very significant departure from the ordinary course, which involves an expert dealing with matters such as this in his evidence as assumptions, otherwise to be proven in the applicants' case by calling evidence directly from the people who have first hand knowledge of the matters in question. There was no explanation given for this unusual course, simply a bald assertion that it was permitted by s 60 of the Evidence Act.
21 In my view, that is not an approach consistent with the underlying purpose of s 60 of the Evidence Act, nor one which can be encouraged by this Court, particularly in proceedings brought under s 106 of the Industrial Relations Act 1996 ('the Act'), where the fairness of the parties' contracts arise for consideration. In considering those questions, the provisions of s 106(2)of the Act will arise. It provides:
