His Honour proceeded:
"The public had already availed itself of the opportunity to make submissions on the subject of height restrictions; two submissions were made against, and one in favour of the proposed changes. The s 69 report shows that those submissions were taken into consideration in the decision to make the second plan. Having regard to the proximity in time between the public notification of the two plans - the period for submissions on the first draft had closed exactly two weeks before the second draft was advertised - it is unlikely that the views or circumstances of potential objectors had so altered that it was necessary to elicit fresh submissions upon this change.
In my opinion, members of the public, including objectors, who had seen the first advertisement and the first draft plan when it was exhibited, would not have been led by the second advertisement to believe that the first draft was no longer on foot. It is probably more likely that they would have believed that the changes in the first draft plan were being considered, while an entirely distinct proposal was being notified by means of a second advertisement".
26 Lloyd J concluded:
"I find that the public notification that took place, which included the notice of 1 June 2000, satisfied both the form and the purpose of s 66. In form it satisfied the technical requirements of the Act. In substance, although the notice of 1 June 2000 contained an explanation which did not itself give a complete picture of the proposed plan, in the circumstances of the case it nevertheless fulfilled the function of relevantly informing the public of the proposed changes and the function of allowing public participation in the making of the plan. In short, I find that the extra material which Council included in that advertisement did not defeat 'the beneficial effect of the giving of public notice' ( Litevale at 102) because the public, only a month earlier, had had proper notice of those changes which that advertisement neglected to mention, and an opportunity to make submission thereon. There can be no suggestion that any member of the public was misled".
27 Mr Preston SC, senior counsel for the appellant, drew attention to the fact that Lloyd J had found that, "taken in isolation", the Second Draft Plan was misleading, that it was "technically incomplete" and that it did not "give a complete picture of the proposed plan". He submitted that, firstly, Lloyd J was wrong to have regard to the "context" (it was said that he should have considered the notice of the Second Draft Plan alone) and, secondly, even if regard could be had to the context, Lloyd J had erred in finding that the notice of the First Draft Plan formed part of the relevant context.
28 Mr Rigg supported the reasoning of Lloyd J but first submitted, in effect, that his Honour was wrong in finding that the notice of the Second Draft Plan, when looked at without reference to the notice of the First Draft Plan, was misleading.
29 Mr Rigg argued that the words in the later (second) notice, referring to the recognition of the difference between larger shopping centres and small neighbourhood shops, would have alerted any reasonable reader to the fact that the Second Draft Plan incorporated limitations to the height of certain buildings. He submitted, in effect, that such limitations would be an inevitable consequence of the "difference" to which the notice referred.
30 I do not accept Mr Rigg's submissions. Inherent in his argument is that it was implicit in the stated purpose of recognising the difference between larger shopping centres and small neighbourhood shops that the act of recognition involved making planning changes appropriate to that "difference" and that one such change was the new height limitation. Firstly, when looked at alone, the implication contended for does not readily arise from the ordinary meaning of the words used. The word "recognises" implies the acknowledgment of existing differences and not the implementation of changes. Secondly, the statements in the notice that one of the purposes was to "simplify and consolidate all recent changes" and that "the Plan does not alter any of the recent changes made to the Business Zones" reinforce the impression conveyed by the word, "recognises". Thirdly, in my view, no reasonable reader would be warned by the words used that the draft plan proposed a change to the height restrictions.
31 The Council was not required by s 66 to provide any information in the notice about the purpose of the draft plan being exhibited. However, once having provided an explanation, that explanation needed to be accurate and complete. It was not. The change involving height restrictions was a material matter: Leichhardt Municipal Council v Minister for Planning [No 2] (at 88 to 89). It should have been part of any description of the purpose of the Second Draft Plan. It was not. The notice, looked at on its own, was misleading. This was the view of Lloyd J and I think his Honour was entirely correct in this respect.
32 I turn now to the opinion expressed by Lloyd J that the notice should not be looked at on its own, but, rather, in context, and that the context included the notice for the first Draft Plan. It was on this basis that his Honour said that, "because the public, only a month earlier, had had proper notice of those changes," there could be no suggestion that any member of the public was misled.
33 Had the notice of the Second Draft Plan referred expressly to the earlier notice, it would have been readily arguable that regard should be had to the earlier notice in determining whether the notice of the Second Draft Plan was misleading. But the notice of the Second Draft Plan neither expressly nor impliedly made any reference to the earlier notice. There is no basis on which it could be said that the earlier notice was incorporated by reference into the later notice. In my opinion, the earlier notice did not form part of any relevant context in which the notice of the Second Draft Plan is to be construed. On this ground alone, in my view, it is not permissible to have regard to the earlier notice. The notice of the Second Draft Plan must be regarded as misleading in a material respect.
34 There was some discussion during the course of argument as to whether a person who read both notices might be misled by the later notice. In my view, this question must be answered in the affirmative. Some five weeks elapsed between the two notices. Both the First and Second Draft Plans were for land within the 3(a) and 3(c) zones; they concerned the same subject-matter. It is not beyond the bounds of reasonable possibility that, for that reason, a person who read both notices might have believed from the terms of the notice of the Second Draft Plan that the Second Draft Plan was intended to replace the First Draft Plan and therefore did not involve limiting the height of buildings.
35 In my opinion, it is likely that persons who read only the notice of the Second Draft Plan (and did not read the first notice) would have been misled. Such persons, on reading the second notice, would probably have believed that the Second Draft Plan did not involve the limitation of building heights. It is conceivable that, between the dates on which the two notices were published, some persons first became interested in land affected thereby. Such persons might not have taken the trouble to read the first notice but, later, might have read the notice of the Second Draft Plan. As I have stated, there is a probability that they would have been misled by the latter notice.
36 The respondent submitted that, should it be held that the notice of the Second Draft Plan was invalid because it was misleading, the whole of Amendment 23 should not be declared to be invalid. The respondent submitted:
"[B]y virtue of s 32(3) of the Interpretation Act 1987 (NSW), only the two-storey height limit, which is quite severable, would be ineffective, and the rest of the Plan, mainly the changes to nominal zoning, would remain valid".
37 Section 32 of the Interpretation Act 1987 (NSW) provides:
"(1) An instrument shall be construed as operating to the full extent of, but so as not to exceed, the power conferred by the Act under which it is made.
(2) If any provision of an instrument, or the application of any such provision to any person, subject-matter or circumstance, would, but for this section, be construed as being in excess of the power conferred by the Act under which it is made:
(a) It shall be a valid provision to the extent to which it is not in excess of that power, and
(b) the remainder of the instrument, and the application of the provision to other persons, subject-matters or circumstances, shall not be affected.
(3) This section applies to an instrument in addition to, and without limiting the effect of, any provision of the instrument or of the Act under which it is made".
38 Section 32(2) applies to any provision of an instrument construed as being in excess of power. In other words, it applies to an instrument part of which is within power and part which is in excess of power. It does not, in my view, apply where there is a lack of power to make the whole instrument. Where the whole instrument is made in excess of power it is a nullity and s 32(2) has no ameliorating effect. This was the conclusion to which Pearlman CJ came in Darling Casino Ltd v Minister for Planning and Sydney Harbour Casino Pty Ltd (1995) 86 LGERA 186 (at 207) and I agree with her Honour in this regard.
39 In any event, the proposition that the provisions relating to height restrictions should be severed from the plan made by the Minister under s 70 (and the remainder of the plan declared to be valid) falls foul of the principle laid down in Olsen v City of Camberwell [1926] V.L.R. 58 (at 68) and followed in several cases since then, see, for example, Dunkley v Evans [1981] 1 WLR 1522, Thames Water Authority v Elmbridge Borough Council [1983] QB 570, Director of Public Prosecutions v Hutchinson [1990] 2 AC 783 and Sloane v McDonald Industries (Sales) Pty Ltd (1989) 17 NSWLR 86. It was approved by the High Court in Harrington v Lowe (1996) 190 CLR 311.
40 The principle in question (as expressed by Cussen J at 68) is as follows:
"If the enactment, with the invalid portion omitted, is so radically or substantially different a law as to the subject-matter dealt with by what remains from what it would be with the omitted portions forming part of it as to warrant a belief that the legislative body intended as a whole only, or in other words, to warrant a belief that if all could not be carried into effect the legislative body would not have enacted the remainder independently, then the whole must fail".
41 The Council's strategic planner, Mr O'Dwyer, reported on 26 April 2000 that recent amendments to the local environmental plan, coupled with the height restrictions amendment proposed in the First Draft Plan, would create an overly complex planning regime in the Hurstville local government area. This led Mr O'Dwyer to recommend the changes reflected in the Second Draft Plan. The Council adopted Mr O'Dwyer's recommendations and decided to deal with the proposal for height restrictions and the proposals for zoning changes in a single plan, namely the Second Draft Plan. It seems therefore that the Council resolved to approve the Second Draft Plan because of the desirability of implementing the height restrictions "coupled with" the need to reduce the number of sub-zones. That being so, it is not possible for this Court to determine whether the Council would have approved the Second Draft Plan without the height restrictions.
42 In the circumstances, I would not accept the submission that there should be severance in regard to Amendment 23.
43 In the circumstances, I propose the following orders:
