Consideration of these grounds of appeal
144It is not disputed that the Council has the broad and general powers conferred on it by ss 21-24 of the Local Government Act and s 50 of the Interpretation Act.
145However, in the present case, the difficulty is that what the Council has done, on his Honour's construction of the clause, in purporting to fix the annual rates at $100,000 subject only to rate pegging increases, is to fetter its future discretion to consider matters that it is required to consider and determine as part of the process of fixing rates in accordance with its statutory obligations: such as to consider submissions that might be made in the future by other rateable land holders as to the provisions of draft management plans that Council would, on this hypothesis, have to have "retro-fitted" in order to comply with the cap on rates fixed under the antecedent Road Agreement.
146It is not to the point, the Council says, that a council can, for example, discriminate against particular land owners by creating a particular sub-category into which only certain land could fall (as was recognised in Marrickville Metro). I agree. Nor is it to the point that it would be arithmetically possible for the Council, each year, to prepare a draft management plan that included the setting of an ad valorem amount that equated to the agreed amount (i.e., $100,000 together with any rate pegging adjustments).
147The fact that it is possible arithmetically or administratively to engage in a "retrofitting" process when setting rates for the next year does not take into account the fact that if another landowner in the area sought to bring itself within the particular category into which the Gingko Mine fell, or submitted that the draft management plan should not be adopted because, say, rates for the Gingko Mine were disproportionately lower than rates levied for other land, the Council would be required properly to consider those submissions. Any such consideration could be no more than perfunctory if the Council had already bound itself to levy rates in accordance with an arrangement such as that provided for by the Road Agreement.
148Moreover, the Council would on that scenario be inhibited in the future from determining the "fair" imposition of rates across all rateable land if the ad valorem rate for the Gingko Mine was required to be retrofitted in the way the appellants maintain it was open to the Council to do. Any landowner in the relevant category would then be entitled to be assessed by reference to the same ad valorem rate. Hence Council's discretion as to the levying of rates on others in the relevant category would be affected.
149In Ansett at 75, Mason J (as his Honour then was) referred to town planning cases where it was held that the relevant authority could not, by contract, fetter in an anticipatory way its future discretion to approve or reject applications after proper consideration in accordance with the prescribed procedure, citing Ransom & Luck Ltd v Surbiton Borough Council [1949] Ch 180 at 195, 198 (see also Southend-on-Sea Corporation v Hodgson (Wickford) Ltd [1962] 1 QB 416; Rocca v Ryde Municipal Council [1962] NSWR 600; (1961) 79 WN (NSW) 299). His Honour noted at 76 that, in such a case, where the contract or undertaking was not one authorised by the relevant legislation or was incompatible with it, the contract or undertaking was invalid or ultra vires. Somewhat inconsistently with their grounds of appeal, the appellants appeared to acknowledge in oral submissions that the fetter principle would apply to agreements which are inconsistent with the legislation. In my opinion such a concession is well-founded.
150Here, subject to the appellants' argument as to s 564 which I consider in (b) below, there is no express statutory power for the making of a contract fixing land rates for a considerable period into the future. Therefore, to the extent that the contract commits the Council in the future to exercise its statutory power in a particular way, it infringes the principle articulated in Ansett.
151It cannot be said that the general power to enter into contracts overcomes this difficulty. In Darkinjung Pty Ltd v Darkinjung Local Aboriginal Land Council [2006] NSWSC 1008, Barrett J (as his Honour then was) said at [72]:
In all cases where a corporation owes its existence to a statute, it is open to the corporation to do only those things that the statute contemplates are to be done by it. It is commonplace for a founding and enabling statute to contain express statements with respect to the purposes, objects, functions, powers and duties of the corporation. Those express statements, together with the necessary implications to which they give rise, are the source of the corporation's authority and capacity and the limits upon them. Where the corporation purports to act beyond the field of its authority and capacity thus defined, its acts are void.
and at [129]:
These cases proceed on the basis of three main principles. First, it is recognised that a grant of incorporation by Parliament carries with it not only rights and privileges but also duties and responsibilities. Second, the duties and responsibilities, as well as existing for the benefit of the section of the population directly affected, are of a public or quasi-public nature. Third, the corporation may not act to abdicate or evade its statutory duties and responsibilities, even if the means by which it purports to do so otherwise appear to lie within the scope of its objects, functions and powers.
152Unless authorised by s 564 (which I consider below), an agreement to fix future rates up to 20 years in advance is not one expressly authorised by the Local Government Act. Insofar as the Road Agreement has fettered the ability of the Council properly to consider matters that might in future be required to be considered in relation to the making of rates, as I consider it did, it is incompatible with the legislation. His Honour did not err in so concluding.
153As to each of the particular grounds raised, in summary I have concluded that:
(1) subject to the conclusion as to ground 6, clause 3.1 of the Road Agreement was not authorised by the Local Government Act;
(2) again, subject to the conclusion as to ground 6, clause 3.1(a) was inconsistent with the Local Government Act because it purported to fetter the Council's exercise of its statutory duties in the making and levying of rates;
(3) an agreement that purports to fetter the Council's exercise of its statutory duties in the making and levying of rates could only be entered into if expressly authorised by the Local Government Act;
(4) his Honour did not err in considering the doctrine, analogous to the doctrine of ultra vires, that the repository of a statutory discretionary power is not permitted to fetter or bargain away such a power;
(5) the doctrine precluding the fetter by a public body entrusted with statutory powers and duties of those powers and duties (considered in Ransom & Luck Ltd v Surbiton Borough Council [1949] Ch 180 and discussed in Review of Administrative Action, Harry Whitmore & Mark Aronson, as long ago as 1978 - see at 234-235) was relevant when considering the validity of clause 3.1(a);
(6) his Honour did not err in concluding that clause 3.1(a) was a fetter of the Council's discretion to determine rates as distinct from a record of the exercise of the relevant discretion to determine rates (for the reasons I set out under category (c) of the grounds of appeal);
(7) the Council's entry into the agreement as to rates contained in clause 3.1(a) was ultra vires the Local Government Act in the sense that it went beyond the statutory power of the Council;
(8) his Honour did not err in finding that, within the scheme of the Local Government Act, the Council had no discretion to determine rates for the purposes of, and for the period of, clause 3.1(a); and
(9) there was a duty for the Council to determine rates payable each year (s 494).
154This first group of appeal grounds is not made out.
