L(2) = is the average estimated land acquisition cost (per m2) at the time of consent"
10 Clause 5.5 provides for the adjustment of contributions that have already been fixed under other provisions of the plan. The figure C in the formula is the amount fixed by the consent. This is then adjusted to reflect changes in the estimated acquisition cost between the date of consent (L(2)) and the date of payment (L(1)). Clause 5.5 does not authorise any adjustment for changes in the estimated land acquisition cost between the date of the plan and the date of consent.
11 Mr Preston relied on the opening lines of cl 5.5 which he submitted assumed that the contributions will have been adjusted before they were fixed so as to be relative to current day values at the date of consent, but his submission is not supported by the text.
12 The opening words refer to contributions which will have been fixed under other provisions of the plan. They are to be adjusted "at the date of payment", "as follows". When so adjusted they are to be "relative to current day values". If current day values have increased by 25% since the consent the same percentage increase in the contribution would ensure that "contributions" were relative to current day values at the date of payment.
13 In my judgment cl 5.5 does not authorise the fixing of a contribution amount to reflect changes in the estimated land acquisition cost between the date of the plan and the date of the consent, and does not even contemplate that such an adjustment will have occurred pursuant to other provisions in the plan.
14 Unfortunately for the Council its plan does not contain any provision which enables the land cost component of the contribution amount to be fixed by reference to the estimated land acquisition cost at the date of consent to reflect changes in land value estimates from the date of the plan to the date of consent. The recital provisions do not and can not provide the necessary machinery for achieving such an adjustment. The answer of McClellan CJ to question 1 was therefore correct.
15 During the argument the Court asked Mr Preston whether contribution condition amounts were a tax and referred to the definition of a tax given by Latham CJ in Matthews v Chicory Marketing Board (Vic) (1938) 60 CLR 263, 276:
"… a compulsory exaction of money by a public authority for public purposes, enforceable by law, and … not a payment for services rendered."
16 Mr Preston submitted that these amounts were not a tax and referred the Court to a number of decisions, the most relevant being that of Cowdroy J in Meriton Apartments Pty Ltd v Minister for Urban Affairs and Planning (2000) 107 LGERA 363, 377-9 where the authorities are collected. This decision establishes that these amounts are not taxes, and that the principles which govern the construction of taxation legislation do not apply.
17 The fact that such an amount is not a tax does not affect the conclusion reached above because under s 94(11) conditions imposing an obligation to pay such amounts must be "determined in accordance with a contributions plan approved under s 94B" and the plan did not authorise the fixing of a contribution which had been adjusted for changes in land values between the date of the plan and the date of the consent.
Adjustments based on average land value estimates in Shire Plan
18 Question two asked whether the formula in cl 5.5 for quarterly adjustments to the land acquisition component was a "quarterly … variation to readily accessible index figures" within cl 32(3)(b) of the Regulation. Clause 5.5 relevantly provides:
"The land component of a contribution condition amount will be adjusted in line with the latest average land value estimates published in the Shire Plan (Baulkham Hills Shire Council). The average estimates will be reviewed on a quarterly basis and determined by averaging the cost of prime residential land acquisitions (per m2) within the Kellyville/Rouse Hill release area over the previous quarter."
19 When the plan was adopted on 18 July 2000 Appendix A contained the estimated land acquisition cost of $84,082,068 for land required for open space and recreation within the release area. That cost must have been based on some average land value but this was not stated in or readily apparent from Appendix A. Clause 5.5 provides that "The average land estimates will be reviewed on a quarterly basis" in accordance with land value estimates "published in the Shire Plan".
20 The clause authorises adjustments to the land component of a contribution amount to reflect changes in the average estimated land acquisition cost between the date of consent and the date of payment and is effective for that purpose if it complied with cl 32(3)(b) of the Regulation. This provides:
"A council may make the following kinds of amendments to a contributions plan without the need to prepare a new contributions plan:
