Consideration
45 It is well to start with an often quoted statement of principle. In Legal & General Life of Australia v A Hudson Pty Limited McHugh JA stated:
It will be difficult, and usually impossible, however, to imply a term that a valuation can be set aside on the ground of the valuer's mistake or because the valuation is unreasonable. The terms of the contract usually provide, as the lease in the present case does, that the decision of the valuer is "final and binding on the parties". By referring the decision to a valuer, the parties agree to accept his honest and impartial decision as to the appropriate amount of the valuation. They rely on his skill and judgment and agree to be found by his decision.
46 And:
… as between the parties to the main agreement the valuation can stand even though it was made negligently. While mistake or error on the part of the valuer is not by itself sufficient to invalidate the decision or the certificate of valuation, nevertheless, the mistake may be of a kind which shows that the valuation is not in accordance with the contract. A mistake concerning the identity of the premises to be valued could seldom, if ever, comply with the terms of the agreement between the parties. But a valuation which is the result of the mistaken application of the principles of valuation may still be made in accordance with the terms of the agreement. In each case the critical question must always be: Was the valuation made in accordance with the terms of a contract? If it is, it is nothing to the point that the valuation may have proceeded on the basis of error or that it constitutes a gross over or under value. Nor is it relevant that the valuer has taken into consideration matters which he should not have taken into account or has failed to take into account matters which he should have taken into account. The question is not whether there is an error in the discretionary judgment of the valuer. It is whether the valuation complies with the terms of the contract.
47 McHugh JA found that the mistake made by the valuer was not of the relevant kind. The rent review clause made the decision of the valuer final and binding on the parties to the lease. The lease did not suggest that it would not be final and binding if it was the result of error or mistake or was unreasonable. The decision would still bind the parties.
48 As Mason P observed in Holt v Cox (1997) 23 ACSR 590 at 595 the reasoning of McHugh JA has been frequently followed with approval.
49 Mason P said:
A close reading of McHugh JA's judgment in Legal & General indicates that his Honour was not propounding the view that a valuation will stand regardless of error. Rather he was making the point that mistake is not itself a ground of vitiation: see also Wamo Pty Ltd v Jewel Food Stores Pty Ltd (1983) ANZ Conv R 50. A valuation may contain factual error or embody consideration of matters which should not have been taken into account, but it does not follow that the result is outside that which the contract contemplated would be within the realm of determination by the valuer. As McHugh JA makes plain, "in each case the critical question must always be: Was the valuation made in accordance with the terms of [the] contract? If it is, it is nothing to the point that the valuation may have proceeded on the basis of error or that it constitutes a gross over or under value" (emphasis added).
50 As McHugh JA observed in Hudson, by providing that the decision of the valuer be final and binding, the parties agree to accept the valuer's honest and impartial valuation. They rely on his skill and judgment. The valuation stands even if made negligently. A mistake by the valuer will only matter if it shows that the valuation was not made in accordance with the contract. His Honour made the point that even if a valuation proceeded on the basis of error, or was a gross under or over value, it matters not. Further, a failure to take account of relevant matters (or the converse) is not a vitiating mistake.
51 In my opinion, Palmer J's decision was correct. There is no vitiating error to be found. Once Mr Norris had found the highest and best use as a retail/commercial site, he was not obliged to carry out a detailed feasibility study. He did not have to envisage with precision what building could be constructed on the site on an economically viable basis. The appellant's submission to this effect must be rejected.
52 In any event, it appears from a reading of the valuer's determination that he determined the current market rental having regard to the comparable sales evidence. This was within the valuer's discretion and judgment. The valuer said in his evidence that he adopted a comparable sales technique by using two commercial sites at Parramatta. His Honour accepted this evidence.
53 The use that the valuer made of a land residual exercise was no more than a check. Again, Mr Norris' evidence made this clear. In particular, when he examined a number of such options, he found them to be unhelpful. Indeed, he said that he found the whole land residual exercise unhelpful. The determination itself and the valuer's evidence, accepted by the trial judge, make it plain that the valuer made his determination on the basis of comparable sales evidence.
54 While I do not see that the valuer made any mistake with regard to the conditions of the deferred development consent, regarding car parking and including the need for the developer to obtain a lease from the council (and the associated evidence), even if they occurred they cannot be vitiating mistakes. At the highest they are errors in methodology which are not vitiating errors.
55 It is also apparent that the valuer's use of the deferred development consent was as a guide or check only. The determination was, as I have already stated, based on comparable sales evidence.
56 In relation to the comparable sales used, it is clear that the valuer made adjustments and his evidence confirmed this. He was not shaken in cross-examination and his Honour accepted the evidence.
57 In utilising the two comparable sales, there was no evidence to suggest that they were not comparable or that there was any error in measuring their degree of comparability.
58 This case is a far cry from McCathie where five properties were averaged. As compared to the present case it is easy to see the vice of the averaging referred to by Williams J at page 15.
59 I am unable to see how the expert failed to follow the usual valuation principles in the State. In this regard, I accept the submission on behalf of the first respondent that there is no valuation principle or doctrine of economic feasibility. No issue is taken that the valuer could not conclude that the highest and best use of the land was as he found. Once that is accepted, the valuer is not obliged to work out precisely what could be constructed on the land and proceed to viability studies and the like.
60 As to the submission concerning the sufficiency of reasons of the valuer, I can see no error in his Honour's approach. In my opinion, the valuer's reasons were quite sufficient for the purposes for which they were required by the lease.
61 The reasons the valuer gave were sufficient to enable the parties to see whether clause 1(d) had been complied with in the valuation exercise. Detailed reasons, such as to be provided by a judicial officer or arbitrator, are not required. This valuer was appointed to act as an expert and not as an arbitrator. Gillard J discussed the standard of reasons usually required of a valuer in The Commonwealth v Wawbe Pty Limited (Unreported, Supreme Court of Victoria, 25 September 1998). I agree with his Honour's observations. The form of the particular clause in this lease requiring 'sufficient reasons' does not detract from the force of what Gillard J said.
62 In any event, even a judge does not have to detail every factor seen as relevant or irrelevant or itemise every fact taken into account. Judicial reasons are not required to be elaborate. Rather they need to be such as indicate to the parties why and on what basis the decision was made. Step by step reasons to a conclusion are not required.
63 In my view, Mr Norris gave sufficient reasons to satisfy the requirement of the lease.
64 Accordingly it is unnecessary to deal with the contention of the first respondent.
