Leave is Refused to Adduce the Proposed Expert Evidence
43In DEXUS Funds Management Ltd v Blacktown City Council [2011] NSWLEC 156 Craig J summarised the legal principles applicable to a grant of leave to adduce expert evidence in judicial review proceedings commenced in Class 4 of this Court's jurisdiction (at [8]-[9]):
8.The Court of Appeal has recently had occasion to consider UCPR 31.19. In Shellharbour City Council v Minister for Planning [2011] NSWCA 195 Giles JA said (at [35]):
"The primary purpose of the rule is to control the calling of expert evidence, restricting it to that which is reasonably required to resolve the proceedings having regard to the admonition of just, quick and cheap. That evidence may be relevant and admissible is not enough, let alone that it is possible to argue that it is relevant and admissible."
His Honour's observations made clear that relevance and admissibility alone will be insufficient. When exercising the discretion available under the rule, it is necessary to determine whether the evidence is "reasonably required" in order to ensure the just, quick and cheap disposition of the real issues in dispute.
9.It is well established that the scope for admissible expert evidence in judicial review proceedings is very confined. Indeed, the scope for evidence that was not before the decision maker is limited: (Attorney-General for the Northern Territory v Minister for Aboriginal Affairs (1989) 23 FCR 536 at 539-540; McCormack v Deputy Commissioner of Taxation [2001] FCA 1700; (2001) 114 FCR 574 at [37] - [38]; ULV Pty Ltd v Scott (1990) 19 NSWLR 190; Woolworths Ltd v Wyong Shire Council [2005] NSWLEC 400). While it is accepted that evidence may be adduced in such proceedings of material available to the decision maker had appropriate enquiry been made (Prasad v Minister for Immigration and Ethnic Affairs [1985] FCA 47; (1985) 6 FCR 155), such an enquiry is not sought to be the subject of expert evidence to be adduced in this matter, assuming that such evidence could ever properly be the subject of expert material.
44In Shellharbour City Council v Minister for Planning [2011] NSWCA 195 the Court of Appeal held that the trial judge had correctly taken the view "that a substantial contest of experts would be a waste of time and money, having regard to her assessment of the unlikelihood that it could be of assistance" (at [29] per Hodgson JA).
45Generally in judicial review proceedings, only the material that was before the decision-maker at the time the decision was made is relevant. This is because judicial review examines the lawfulness of the decision and not its merits. While there are a number of limited exceptions to this general principle, depending on the circumstances of the case and the challenges made to the decision under review (see DEXUS (at [9]); Moolarben Coal Mines Pty Ltd v Director-General of the (former) Department of Industry and Investment NSW (Agriculture Division) [2011] NSWLEC 191 (at [69]-[76]) and INL Group Ltd v Director-General, New South Wales Department of Planning [2011] NSWLEC 256 (at [31]-[32])), none are applicable here.
46In DEXUS a declaration of invalidity was sought in relation to the granting of a development consent for the construction of a new shopping centre by Blacktown City Council. Four grounds upon which the decision of the Council was claimed to have miscarried were pleaded. First, that the Council failed to give any proper consideration to parking and traffic impacts upon local roads and traffic signal-controlled intersections in the vicinity of the proposed development. Second, that a deferred commencement condition was said to be lacking in finality and certainty in a number of nominated matters. Third, that the Council failed to give any proper consideration to matters concerning contamination of part of the land the subject of the consent. And fourth, that the grant of development consent was manifestly unreasonable.
47These grounds are analogous to the grounds of review pleaded in the present case.
48In refusing to grant leave Craig J opined as follows (at [13]):
13 In considering these matters, the task of this Court when determining the proceedings will be to assess the information that was before the Council in order to determine whether it has failed to consider the matters pleaded in paragraph 14 of the points of claim. Expert evidence directed to the sufficiency of that information or whether the Council failed to consider matters or was satisfied as to matters about which it was required to be satisfied are all issues of fact in respect of which expert evidence would not appear to be admissible.
49In my opinion his Honour's comments are directly applicable to the present application. I respectfully adopt and apply them.
50Craig J went on to reason that (at [17]-[22]):
17 Observations similar to those made in respect of the proposal to call a contaminated land expert apply with equal force to the directions sought to call a traffic expert. DEXUS has pleaded the manner in which there was a failure to consider relevant considerations in relation to traffic and parking matters. Documents before the Council or available to it at the time of making its decision must surely be the basis upon which the Court will determine whether relevant matters were considered. Assuming, as I am told was the case, that there was expert evidence available to the Council a the time of making its decision, the calling of expert evidence to express a different opinion would not be evidence relevant to be considered in judicial review proceedings.
18 It was suggested on behalf of DEXUS that "various factual matters" upon which it seeks to rely "can only be identified with the assistance of expert witnesses". That statement does not appear to support, on a ground relevant to the present proceedings, the basis upon which evidence should be adduced. If the role of the intended experts is to identify "factual matters" then that expert is in no better position to do so than is the Court.
19 The prospect that the evidence sought to be adduced by DEXUS will impermissibly slide into merit review is exemplified by the manner in which its written submissions identify the "relevant factual matters" that it seeks to have addressed. I do not recite all of them but nomination of three of them will exemplify the proposition. They are:
"(i) the identification of matters which should have been considered by Council in respect to traffic;
(ii) the identification of impacts which should have been considered in respect to such matters
...
(vii) in particular the impacts which should have been assessed as to the likely impact of traffic control signals at the changed eastern access to the site in respect to ... " (Emphasis added)
20 In similar vein, the "relevant factual matters" required from the land contamination expert identified propositions of which the first is an appropriate example:
"(i) that the information before Council at the time it determined the application was insufficient to enable it to conclude whether and to what extent the land is contaminated"
21 All of these matters of "fact" ought not, for the purpose of judicial review, require expert evidence. Rather, at least as they are framed both in the letter of particulars provided by DEXUS and articulated in the written submission, they are matters that are capable of being argued on the basis of the material provided to or available to the Council at the time of its determination.
22 I do not overlook the claim made by DEXUS alleging that the Council's decision was manifestly unreasonable. However, as this claim is pleaded simply by reference to the traffic and contaminated land issues said not to have been considered by the Council, it does not appear to me to be a ground that gives rise to an independent basis upon which to direct expert evidence.
51Again his Honour's reasoning is apposite. In this case, there is clearly a risk that the particular expert evidence that Mr Rossi seeks to adduce will slide impermissibly into merits review. This is illustrated by the manner in which the orders sought in the notice of motion identify the relevant considerations that ought to have been taken into account by the JRPP and the council in determining the DA. For example, the evidence of Mr Hill is sought to demonstrate (emphasis added):
1.When determining the development application, what the JRPP as the decision maker and the Council as the consent authority ought to have taken into consideration of relevance to the development the subject of the development application...
52Similarly, Mr Betro's evidence is allegedly required to show (emphasis added):
6.What engineering issues arise... that ought to have been considered in the determination of the development application by the decision maker and consent authority.
7.Whether the decision maker failed to take into account the matters that it ought to have given the extent of land-filling approved by the Development Consent.
53Although these alleged discrepancies between what was and what "ought to have been" considered may provide a foundation for arguing that the documentation that was put before the JRPP was inadequate, this does not, as presently pleaded, properly sound in an action for judicial review. First, the claims by Mr Betro are not anchored to any identifiable statutory contravention. Second, the omissions are matters that are capable of being argued on the basis of the material that was before the JRPP at the time it made its decision. That is to say, either the JRPP had, assuming it was relevant, the material before it and failed to consider it, or it did not have material that it was obliged to consider. Either way, it is the statute that is the objective touchstone of what material the JRPP should have taken into account, not the subjective views of Mr Betro.
54Mr Rossi submitted that Mr Hill is required to give evidence regarding:
(a)what environmental planning instruments applied to the development application and in what respects;
(b)what development control plan/s applied to the development application and in what respects;
......
(h)whether and if so in what respects the development has been carried out otherwise than in accordance with the development consent.
55Not only are these matters not the subject of any allegations in the pleadings, they are matters that, with respect to Mr Hill, the Court is best placed to determine because they require the interpretation, construction and application of environmental planning instruments.
56The evidence of Mr Beasley concerns "identifying by accurate survey the work that has been carried out since the grant of development consent" in order to determine the volume and placement of cut and fill along the common boundary. But the determination of these facts is not relevant to the validity of the development consent as pleaded.
57As the recitation of the claims pleaded against the respondents demonstrates, the proposed expert evidence cannot assist the Court. The matters pleaded require an objective assessment as to whether or not the alleged breaches have occurred. The subjective views of the putative experts are irrelevant. These are judicial, and not merits, review proceedings.
58If, as is submitted, there has been a failure by the JRPP to consider matters concerning the fill in the approval of the development application, this will be, as I discussed above, manifested by recourse to the material before the JRPP. To reiterate, stated above, either the JRPP has considered, or properly considered, these matters, assuming Mr Rossi is able to demonstrate as a matter of law that they are required to be taken into account pursuant to the EPAA or some other statutory instrument, in which case Mr Rossi will fail; or the JRPP has not, in which case Mr Rossi will almost certainly succeed.
59Mr Rossi further submitted that the expert evidence was directly relevant to the exercise of discretionary relief, in particular the claim for demolition and removal of the fill from the common boundary.
60Assuming Mr Rossi is successful in obtaining a declaration that the development consent is invalid, it is possible that expert evidence will, at this point, become necessary to the question of the appropriate relief to be granted.
61However, having regard to the overriding purpose contained in s 56 of the CPA, as informed by the principles contained in ss 57-60 of that Act, it would be neither "quick, just" nor "cheap", to put the respondents to the cost and inconvenience of adducing expert evidence of the type foreshadowed by Mr Rossi at this stage of the proceedings in order to meet a claim for relief that may never eventuate. If Mr Rossi is ultimately successful in his quest for invalidity, then the issue of relief on the question of discretion can be determined at this stage.
