CONSIDERATION
25 In my view, the appropriate way to proceed is to start with the question of whether the valuation complies with s 75-10(3) of the GST Act. To be a compliant valuation it must accord with the Determination. If a valuation complies with the Determination, then the valuation is valid and operative for the purposes of s 75-10(3). However, if the valuation fails to comply with the Determination, then the question will arise as to the consequences of such failure.
26 This approach involves an analysis of the construction of the GST Act, and the result of any non-compliance being determined by reference to that construction: see, eg, Project Blue Sky Inc v Australian Broadcasting Authority (1998) 194 CLR 355, 390-91; and Tasker v Fullwood [1978] 1 NSWLR 20, 23-4.
27 In some cases, compliance with a statutory requirement allows for no middle course, and is obligatory: see Hunter Resources Ltd v Melville (1988) 164 CLR 234, 249 per Dawson J.
28 In the case of a valuation under the Determination, it is clear that a valuation must be provided by a professional valuer. There could be no middle course here - if not provided by a professional valuation there would be no 'valuation'.
29 Equally the valuer 'must' have regard to three matters: the market value of the completed premises; the cost to complete the partly completed premises; and the profit margin and holding costs that are attributable to the period on or after the valuation date. Further, these matters would need to be given appropriate weight as important or essential elements in the making of the valuation: see R v Hunt 180 CLR 322, 329. If the valuer did not have regard to these three matters, nor give them appropriate weight, then the language of s 75-10(3) and purpose for the valuation coming into existence, indicate that the valuation would be invalid and of no operation for the purposes of the Determination.
30 However, just because another valuer may come to a different valuation figure does not mean that the valuation relied on may not be in compliance with the requirements of s 75-10(3) and the Determination. Within any valuation there will be matters of subjective judgement undertaken by the professional valuer based upon his or her expertise and experience.
31 The fact that there may be matters of subjective analysis undertaken is encompassed and envisaged by the Determination which relies upon a professional valuer undertaking the task and coming to a valuation. However, in reaching the final valuation, the professional valuer must not deviate from the method of valuation dictated by the terms of the Determination. In this proceeding, the hypothetical development method of valuation was in fact adopted, and was the appropriate method as required by the Determination. To the extent that there are judgement calls to be made within the application of that method, then this would be a matter for the valuer's professional expertise upon which minds may differ in arriving at a particular value.
32 In considering this matter, I have not found much assistance from the cases relied on by the taxpayer. The question is one of compliance with a statutory requirement and the consequences of any non-compliance. We are not dealing with a contractual setting, nor with the exercise of a power by a public official. However, even if it were appropriate to apply by analogy the principles referred to in Peko-Wallsend Ltd 162 CLR 24, no different result would be reached in this proceeding. In the end it is a matter of determining what factors the professional valuer was bound to consider, and then to determine whether the failure to take into account a particular factor would result in invalidity.
33 It is thus now necessary to address the application of Method 1 by Mr Nicodimou.
34 As set out in cl 5 of the Determination, the methodology requires the valuer to assess the market value of the completed premises as at 1 July 2000, and then subtract from this figure the costs to complete the partially completed premises and the profit margin and holding costs. What is left is the price that the hypothetical developer would pay for the partially completed premises on 1 July 2000 and that is the value of those premises on 1 July 2000.
35 Mr Nicodimou applied Method 1 as follows:
Valuation of completed property(1) $54,141,275
LESS: Cost to complete(2) $18,843,000
25% Profit & Risk(3) $10,532,255
Interest $1,912,693
Valuation of Incomplete Property as at 1 July 2000 $22,929,000
