11 The experts agree that the highest and best use of each of the subject sites is the existing use, namely commercial office development with basement level retail.
12 Section 6A of the Valuation Act is relevant for the purpose of the valuation of the subject sites. It provides:-
(1) The land value of land is the capital sum which the fee-simple of the land might be expected to realise if offered for sale on such reasonable terms and conditions as a bona-fide seller would require, assuming that the improvements, if any, thereon or appertaining thereto, other than land improvements, and made or acquired by the owner or the owner's predecessor in title had not been made.
(2) Notwithstanding anything in subsection (1), in determining the land value of any land it shall be assumed that:
(a) the land may be used, or may continue to be used, for any purpose for which it was being used, or for which it could be used, at the date to which the valuation relates, and
(b) such improvements may be continued or made on the land as may be required in order to enable the land to continue to be so used,
but nothing in this subsection prevents regard being had, in determining that value, to any other purpose for which the land may be used on the assumption that the improvements, if any, other than land improvements, referred to in subsection (1) had not been made.
(3) Notwithstanding anything in subsection (1), in determining the land value of any land, being land in relation to which, at the date to which the valuation relates, there was a water right:
(a) the land value shall include the value of the right, and
(b) it shall be assumed that the right shall continue to apply in relation to the land.
It is agreed that s 6A(2) of the Valuation Act is particularly relevant due to the over-development of the subject sites.
13 Section 4 of the Valuation Act defines "land improvements" as follows:-
Land improvements means:
(a) the clearing of land by the removal or thinning out of timber, scrub or other vegetable growths,
(b) the picking up and removal of stone,
(c) the improvement of soil fertility or the structure of soil,
(d) the restoration or improvement of land surface by excavation, filling, grading or levelling, not being works of irrigation or conservation,
(d1) without limiting paragraph (d), any excavation, filling, grading or levelling of land for the purpose of the erection of a building, structure or work, not being for the purpose of irrigation or conservation,
(e) the reclamation of land by draining or filling together with any retaining walls or other works appurtenant to the reclamation, and
(f) underground drains.
14 The parties also agree that the recent decision of the High Court of Australia in Maurici v Chief Commissioner of State Revenue (2003) 212 CLR 111 is relevant although the Valuer-General submits that Maurici does not dictate the appropriate method of valuation in the present proceedings. It is appropriate to summarise the findings in Maurici since these proceedings appear to be one of the first instances in which the Court may have need to consider the application of the High Court's decision.
15 In Maurici the High Court was concerned with the valuation of a parcel of land in the Sydney suburb of Hunters Hill pursuant to s 6A of the Valuation Act. At par 16 the High Court stated that s 6A of the Valuation Act firstly requires improvements "other than land improvements" to be identified; secondly "notionally to remove the improvements from the land"; and thirdly to determine how "the land in its notionally unimproved state [is] to be valued". It is the third step which the High Court recognised as the stage at which "difficulties arise". Their Honours said at par 16:-
The traditional, and usually unexceptionable method is to seek out relatively contemporaneous sales of comparable properties between parties at arm's length, unaffected by special circumstances, such as, for example, a strong desire by a purchaser to buy an adjoining property, and to use those sales as a yardstick for the valuation of the relevant land.
16 The High Court at par 17 criticised the evidence of the Chief Commissioner of State Revenue's valuer for refining comparable sales to sales of vacant or substantially vacant land because such sales were not representative of sales in Hunters Hills "as vacant land in Hunters Hill is scarce, if not to say, very scarce". The High Court continued with the following comment at par 17:-
The approach of the respondent, taken to its ultimate conclusion would mean that if there were one only (reasonably comparable, in location, outlook and other relevant features) vacant parcel of land left in a district, the likely or actual recent sale price of that parcel would effectively set the value for each and every improved parcel of land in that district.
17 At par 18 the High Court made it clear that in valuing land the following principle cannot be ignored:-
…that sales to be treated as comparable sales need to be truly comparable; or, to put it another way, in valuing the land the respondent's valuer did not proceed rationally, in that he was unreasonably selective in ultimately confining himself to two sales of scarce vacant land for the purposes of the comparison… A group of comparable sales cannot be representative if it does not go beyond sales of scarce vacant land.
