CONCLUSION
59 For those reasons, in my opinion condition 56 is valid, effectual and enforceable. No breach has yet arisen, because the request made by Westfield did not offer, or at least did not offer with sufficient clarity, appropriate terms as to maintenance of the right of way and insurance.
60 As I understand it, this decision on Westfield's appeal from Land & Environment Court proceedings 41349 of 2004 makes it necessary for there to now be a determination of the application brought by Perpetual (Land & Environment Court proceedings 10114 of 2005) against the deemed refusal of its application under s.96 of the EPA Act to modify development consent No. 44/85/0257. That application was not heard by the Court below and it will now need to be heard. The primary judge also did not resolve the issues raised by Westfield's application (Land & Environment Court proceedings 40227 of 2005) seeking a declaration that the Council cannot be satisfied that the development to which the consent to development application No. 44/85/0257 relates, if modified, will be substantially the same development for which development consent was originally granted by the Council, as modified. It may be that some of the costs of the first instance hearing in this matter will be relevant to those applications. There is also a question as to the costs of this matter below, in circumstances where breach of condition 56 was alleged and, on the view I have taken, not proved. In my view, the costs at first instance should be left in the discretion of the judge who deals with these applications.
61 For those reasons, in my opinion the following orders should be made:
1. Appeal allowed, orders below set aside.
2. Perpetual to pay Westfield's costs of the appeal.
3. No order as to the Council's costs of the appeal.
4. Declaration that condition 56 is valid and enforceable.
5. Cross-claim dismissed.
6. Matter remitted to the Land & Environment Court for decision as to the costs of the first instance hearing.
62 TOBIAS JA: In this matter I have had the benefit of reading in draft the judgments of Hodgson JA and Basten JA. I agree with the orders proposed by Hodgson JA for the reasons given by him and for the additional reasons articulated by Basten JA. However, like Basten JA, I find it unnecessary to express a view on the question of severance.
63 As Basten JA points out in [75] of his judgment, the central issue in the appeal was the validity of condition 56. It was common ground, and acknowledged by the primary judge, that the condition would not be valid unless it met the three-fold test articulated by McHugh J in Temwood Holdings which Hodgson JA has set out in [35] above.
64 The primary judge found that the first and second of those facts were satisfied in that condition 56 was imposed for a planning purpose and reasonably and fairly related to the Glasshouse development. Its planning purpose was the ultimate deletion of vehicular traffic movements from the Pitt Street Mall. I accept that, as Basten JA observes in [85] of his judgment, such a planning purpose would only be legitimate if it derives from the statutory source of the power being exercised. In my opinion, the powers vested in the Council by the Environmental Planning and Assessment Act 1979 were more than adequate to encompass not only the provision of the Pitt Street Mall as a pedestrian thoroughfare, but also the adoption of controls to remove from it all vehicular traffic.
65 Condition 56 also met the second requirement insofar as it related to the Glasshouse development which was in a critical location on King Street to provide vehicular access to the properties to its south as far as Market Street. I would further endorse the finding of the primary judge that is recorded in [87] of Basten JA's judgment as a further basis upon which the second test referred to by McHugh J in Temwood Holdings was satisfied.
66 The validity of condition 56 foundered before the primary judge upon the third test referred to in Temwood Holdings. His Honour's conclusion (at [71]) was that it was devoid of plausible justification such that no reasonable council could have imposed it. Although his Honour coupled that find with the further finding that the condition amounted to a relevant abuse of power, I do not understand him to be backtracking, as it were, upon his earlier finding that the condition fairly and reasonably related to the Glasshouse development. Rather, as [66]-[74] of his judgment illustrated, his Honour dissected the condition in a manner which emphasised his perception of its negative and uncertain qualities which led him to the conclusion that, in all the circumstances, no reasonable council, properly advised, could have it imposed it.
67 However, as Hodgson and Basten JJA make clear, it is difficult if not impossible to characterise the imposition of the condition as manifestly unreasonable in the Wednesbury sense unless one has first construed it to determine precisely the obligation or burden it in fact imposes upon the owner from time to time of the Glasshouse development. Like Basten JA, I agree with the construction of the condition adopted by Hodgson JA.
68 Properly construed, the condition does not impose any obligation upon the owner of the Glasshouse development unless and until there is agreement between at least the owners of Skygarden and Imperial Arcade (and, preferably Centrepoint), to accept an extension of the easement the terms of which are recorded in [14] of the judgment of Hodgson JA. It would also be necessary for Skygarden to grant an easement over its property in favour of Imperial Arcade and/or Centrepoint. Until both these events occur, condition 56 would not operate to impose any obligation upon the owner of Glasshouse to agree to the extension of the easement to benefit the Imperial Arcade and Centrepoint sites.
69 The point is well made by Hodgson JA in [45] of his judgment with which I respectfully agree. There is no doubt that condition 56 is only to operate upon the basis of the existing easement in favour of Skygarden being extended to the Imperial Arcade and Centrepoint properties with appropriate amendments to give effect to the equal division of costs in the terms referred to by Hodgson JA in [51] of his judgment.
70 Perpetual would only become obligated to grant an extension of the easement, and to comply with the condition, when an appropriate instrument complying with the requirements to which I have referred, has been tendered to it for execution. But the fact that that obligation does not presently exist and has not existed since the condition was imposed, does not render the condition uncertain in its operation to the extent that that factor might otherwise be relevant to a determination of whether the condition is Wednesbury unreasonable.
71 It must always be remembered that the test for Wednesbury unreasonableness is stringent: Weal v Bathurst City Council (2000) 111 LGERA 181 at 188 [27] per Mason P. To qualify, the imposition of condition 56 by the Council must have been "so devoid of plausible justification that no reasonable person could have taken that course". In Murrumbidgee Groundwater Preservation Association Inc v Minister for Natural Resources (2005) 138 LGERA 11 at 41 [129] Spigelman CJ, with whom Beazley JA and myself agreed, considered that the most appropriate formulation was whether the decision
"is illogical, irrational or lacking a basis in findings or inferences of fact supported on logical grounds,"
72 Once condition 56 is construed in the manner to which I have referred, it must follow that the condition is not unreasonable in the Wednesbury sense as I have described it. When regard is had to the history of the matter, the correspondence to and from the Council and the contents of the Planning Committee's report pursuant to which the imposition of condition 56 was recommended, it becomes apparent that its imposition was the quid pro quo for the removal of condition B(b). This resulted in the then developer of Glasshouse being granted bonus floor space without having to surrender the transferable floor space which it had acquired pursuant to condition B(b) and which it could now retain and make available for use elsewhere.
73 In these circumstances, given the true nature and extent of the obligation imposed by condition 56 upon the owner of Glasshouse from time to time, no basis exists for declaring the condition invalid as being illogical, irrational or lacking a basis in findings or inferences of fact.
74 For the foregoing reasons, which generally reflect those of Hodgson JA and Basten JA, I agree with the orders proposed.
75 BASTEN JA: The central issue in this appeal was the validity of condition 56 in a development consent granted by the City of Sydney Council for the construction of a building known as "The Glasshouse" at 131-139 King Street, Sydney. The condition is set out by Hodgson JA at [4] above.
76 With one qualification, I agree with the orders proposed by Hodgson JA, for the reasons given by him and for the additional reasons set out below. The qualification is that, because the question of severance does not arise (the condition in question not being invalid) I would express no views about it. The relevant principles were but lightly touched on in submissions. The condition in question, being condition 56, was in effect imposed in exchange for a favourable variation of the floor space ratio. The practical consequences of any finding of invalidity are so fraught with difficulty that they should not be addressed unless and until necessary: cf Lloyd v Robinson (1962) 107 CLR 142 at 152.
77 In the judgment of the Land and Environment Court in this matter, Westfield Management Ltd v Perpetual Trustee Company Ltd [2005] NSWLEC 510 at [5], the primary judge stated:
"The fundamental issue in each case is the proper construction of conditions 19 and 56 of the modified consent … ."
