(5) Where hearsay or opinion evidence is admissible only because the evidence is relevant for a non-hearsay purpose or is relevant otherwise as opinion evidence (s 60 and s 77), special considerations apply. ( Quick v Stoland Pty Ltd (1998) 87 FCR 371 at 377-8, 382). As Sperling J said in Roche v Page (No 11) at [74]:
"(h) Sections 60 and 77 give rise to special considerations. Unlike other exceptions to the hearsay rule and the opinion rule, it is not the objective of those sections to facilitate proof. They are there to avoid a distinction having to be made about evidence being used for one purpose and not for another. Where a document goes into evidence because the existence of the document is a relevant fact, the operation of these sections without a limiting order under s136 may have a consequence which the legislature cannot have intended. Any representation in the document which is probative of some other element in the tendering party's case becomes evidence of the content of the representation. Representations of fact become evidence of the truth of the representation, irrespective of whether they are first-hand or remote hearsay and irrespective of whether the source of the information is disclosed. Representations of expert opinion in the document are probative of whatever is the subject of the opinion expressed, irrespective of whether the author of the document is qualified to express the opinion and irrespective of whether the assumptions made for the purpose of expressing the opinion are specified. Such consequences cannot have been intended where the opposite party is disadvantaged by such consequences. Section 136 serves to avoid such unfairness."
21 In his affidavit Mr Parkinson exhibited his report but did not elaborate on it. He did not swear to holding the opinions expressed in the report. The explanation for his unavailability to attend for cross-examination is unsatisfactory. Having sworn an affidavit in the proceedings which exhibited his report, he and the plaintiffs' legal representatives must have expected that he would be required to attend for cross-examination on his report and on the circumstances surrounding its creation. His apparently having left the employ of LandMark White is no reason for him not to be available to be cross-examined on his report. If he was unwilling to give evidence he should have been subpoenaed. His reluctance to submit his opinion to be tested by cross-examination and the plaintiffs' failure to compel his attendance for that purpose raises a real concern as to the reliability of the report and the opinions expressed in it.
22 One of the possible areas of unfair prejudice arises from the submission made for the third to fifth defendants as described in paragraphs 15-17 above. The defendants are unable to test Mr Parkinson as to whether his report was prepared wholly or partly with the view of assisting the plaintiffs in a case that they had been induced to enter into the contract of sale through misrepresentations of the property's value. However I do not place much weight on that consideration, as no questions were directed to Mr Young along those lines.
23 Of more significance are the matters set out in the third to fifth defendants' written submissions on the admissibility of the report. They point to evidence of the existence of other valuations of the property, not necessarily of LandMark White. Thus Mr Menere said that he told Mr Abbott that Stanley & Thompson, Valuers, had put a figure of $7,500,000 on the land component (T 307). Exhibit 1D20 refers to a valuation apparently of Herron Todd White of $6,000,000. Mr Young gave evidence of a valuation coming in in about six weeks after 19 June, i.e. at the end of July or early August, although that may have been an earlier valuation of LandMark White at $4,900,000. (T 26, T30). The content of those valuations (which have not been produced by the plaintiffs), if known to Mr Parkinson, might have proved fertile grounds for cross-examination.
24 The report struck a value for the property of $5,000,000 by first carrying out what was called a "direct comparison" with other comparable sites on either a rate per square metre or rate per unit value. Mr Parkinson listed nine such comparable sites. He selected three as being the best comparables having a rate per unit site of $52,574, $73,889 and $82,500. Each was said to be considered superior to the subject site. Without the opportunity for the defendants to test the reasons for his selection of the three sites as being the best comparable sites, his reasons for considering the three selected sites to be superior to the subject site, and his reasons for selecting the figure of about $53,764 per unit site ($5,000,000 divided by 93 see para 6.5.1) for the subject land by reference to the "direct comparables", it is hard to know what to make of his comparison.
25 Mr Parkinson then carried out a "residual cashflow analysis". As I understand the analysis, he projected the likely gross sales from the development once the development was completed. He also projected the likely costs of the development including the costs of construction (about which he disclaimed expertise) on the basis of the assumed construction, selling and other costs, including finance costs at an assumed 100% debt funding at 9%. He calculated that assuming the site had a value of $5,000,000, the development would yield profit after interest of $4,690,000, a "development margin after interest" of 20.57% and an internal rate of return after interest of 18.26%. He appears to have considered that such a profit is what a developer would expect and hence concluded that the cashflow analysis supported his valuation using the direct comparison method. Without the opportunity to test the assumptions and the projections which Mr Parkinson made, it is very difficult to see what weight should be put upon the report.
26 One of the submissions of the third to fifth defendants is that Mr Parkinson had assumed construction costs of $15,500,000 for the development but that there are no details of how that figure was arrived at. There is no evidence from a builder or quantity surveyor to support it. Mr Parkinson disclaimed expertise in making that assessment. The defendant submitted that the figure appeared excessive as it equated to a cost of $1,900 per square metre of living area which Mr Parkinson described as being "at the upper end of the likely building cost range" whereas the range which he quoted from Rawlinson's Australia Construction Handbook was $1,524 to $1,606 per square metre. It was submitted that if a figure of $1,550 per square metre rather than $1,900 per square metre were adopted, the resulting valuation for the site should be in the order of $8,000,000, although the process of calculation was not explained in the submission.
27 I do not see how considerations of this kind can be dealt with in the absence of cross-examination of the author of the report. It is not enough to say that these are questions of weight. The difficulty is that without evidence from the author of the report as to the effect, if any, which the considerations which the defendants might raise in cross-examination would have on his opinion, the Court does not know what weight, if any, should be attached to them.
28 It was also submitted for the third to fifth defendants that Mr Parkinson may have been unduly conservative in his assessment because his report was made for mortgage lending purposes and that a less conservative figure might have been obtained if the valuation was made for the purposes of sale. It was also submitted that had Mr Parkinson made the same analysis as at 19 June 2001 rather than 27 September 2001, the valuation may have been higher because, according to his report for the "past 6 months" extensive supply of units "has impacted on (sic) the activity in this market". Again, these are considerations which cannot be evaluated in the absence of the witness.
