12 Accordingly, as I have said, I would not reject the balance of Mr Edmonds' report on the basis of the Makita objection.
13 I come then to the relevance objection. For reasons that I explained in my judgment of 7 June 2007, the difference between the current value of the subject property and the value which the property would have had if it had been as represented is not the relevant measure of damages. Mr Alexis, however, submits that an order might be made under Trade Practices Act, s 87, for the payment of compensation according to that measure, and further, that demonstration that the current values of the properties are adversely affected by exposure to noise may bear on the discretion to grant injunctive or other relief under s 87.
14 In this context, it is important to appreciate that fundamental to Trade Practices Act, s 87, is the concept of damage suffered or likely to be suffered "by conduct of another person that was engaged in ... in contravention of", relevantly, s 52. That damage is the same damage as is referred to in s 82. As I explained in the judgment of 7 June 2007, it corresponds with the detrimental change of position of the person deceived in reliance on the conduct complained of. In a case such as that of the plaintiffs with whom we are presently concerned, it is ordinarily the difference between the price actually paid for the property, and its true value, ordinarily determined as at the time of purchase: that is the rule in Potts v Miller (1940) 64 CLR 282, to which I adverted in that judgment.
15 What the present argument seeks to do is to have admitted, by a side wind, evidence of "damage" assessed on a different basis and at a different time. In short, it is not evidence of the damage suffered or likely to be suffered by the alleged contravening conduct, but evidence of the quite different subject matter of the present difference between the value of the property "as is" today, and the value it would have had "as represented" today. This would invite the Court to embark on an irrelevant inquiry and open up issues which simply do not need to be addressed in this case. In my view, the fundamental question to which Mr Edmonds' current market values scenarios A and B are addressed is irrelevant.
16 I turn then to the third objection. Mr Alexis concedes that Mr Edmonds has assumed the accuracy of the evidence of Mr Simpkin and Ms Dwyer and of that of Mr Billington and Ms Mather, as to the impact of noise on their apartments, and I agree that that assumption is an essential assumption in each of his reports, such that without it, the ultimate opinion could not stand. However, the evidence of those witnesses on that subject has been admitted, pursuant to (NSW) Evidence Act 1995, s 136, on the limited basis that it was evidence only in Glen Eight's claim for damages in respect of the Azure, as informing an assessment of the impact of noise on the value of units in the Azure, for the purpose of determining the value of the Azure "as is" - not its value "as represented". That, of course, is an entirely different basis from that on which Mr Edmonds has sought to use that evidence. Recognising this, Mr Alexis has foreshadowed that he would seek leave to extend the basis upon which that evidence has so far been admitted, conceding that it would then be necessary to offer to make the relevant witnesses available for further cross-examination.
17 While any such application might have called for more careful consideration if I had been of the view that the evidence was relevant to the s 87 case, as things stand, it reinforces my decision to reject the evidence. Almost three weeks into the trial, when the lay noise evidence, after having twice been rejected, was admitted on the limited basis explained in my judgment of 8 June, ([2007] NSWSC 594), and since then has been consistently admitted on that basis - even to the point that I have referred earlier today to the limited basis on which it has been admitted as "the usual s 136 lay noise evidence order", I think it is too late to revisit that issue - especially in circumstances where almost all of the witnesses who have given that evidence have been cross-examined - or, more significantly, not cross-examined on what they have said about noise - on the basis that the evidence has so far been admitted for that limited purpose, and would have to be recalled for further cross-examination if that position were now to change.
18 Accordingly, although I would not reject Mr Edmonds' reports on the basis of the Makita objection, I hold that the opinions of value which he proffers are irrelevant and, therefore, ought not be admitted, and, in addition, that on the current state of the proceedings, assumptions essential to his conclusions cannot be made good.
