9 According to the pleadings, the following issues require adjudication -
(i) whether the proposed development to which the development consent was granted was relevantly development for the purposes of a " tourist facility " within the meaning of SEPP 71; and
(ii) whether that development, if so characterised, was relevantly State significant development.
10 As will appear the manner in which the case was mutually conducted, issue (i) was not seriously in contest. Rather, having assumed an affirmative answer to the question, the competing cases explored the legal consequences of that affirmative answer for the second of the stated issues. In particular, the second Respondent's case was that in consequence of an affirmative answer to issue (i), it necessarily followed that the development consent had approved development that was prohibited development in terms of the Maclean Local Environmental Plan 2001 (the LEP) and that that result was only legally sustainable by reference to the power that is conferred by the EP&A Regulation concerning the expansion or intensification of "existing uses". The second Respondent argued that once the "existing use" power is necessarily invoked to sustain the development consent which authorised the carrying out of prohibited development, that development cannot in law be State significant development as defined by s 76A(7)(a).
11 If the Applicants are to succeed in their challenge to the validity of the development consent, both issues (which reflect the two ingredients of the statutory concept of State significant development) must be answered in the affirmative.
B. THE LEGAL FOUNDATION FOR THE APPLICANTS' CLAIM
12 The Applicants' case is that no matter how the development consent granted by the Council is legally conceived in terms of the legal permissibility of the approved development (whether or not that permissibility is sourced in the LEP or existing use entitlements under the EP&A Regulation), the development consent nonetheless is a legal nullity because the approved development was relevantly State significant development and the Minister (and not the Council) was the relevant consent authority having the responsibility to determine the development application.
13 "State significant development" is defined by the EP&A Act, s 4(1) as having the meaning given by s 76A(7) which is in the following terms:
(7) State significant development
State significant development is:
(a) development:
(i) that is declared by a State environmental planning policy or a regional environmental plan to be State significant development, and
(ii) that may be carried out with development consent, or
(b) particular development, or a particular class of development:
(i) that, under an environmental planning instrument, may be carried out with development consent, and
(ii) that, in the opinion of the Minister, is of State or regional environmental planning significance, and
(iii) that is declared by the Minister, by notice in the Gazette, to be State significant development, or
(c) development that is proposed to be carried out in accordance with a development application that the Minister has directed, under section 88A, to be referred to the Minister for determination, or
(d) prohibited development in respect of which a direction by the Minister under section 89 is in force.
14 In order to substantiate their legal claim that the approved development was relevantly State significant development, the Applicants who rely in this respect exclusively upon SEPP71, must establish that the approved development was relevantly (i) "development on land to which SEPP71 applies for the purpose of tourist facilities (except bed and breakfast establishments and farm stays)" as referred to in Schedule 2 to SEPP 71; and (ii) was "development that may be carried out with development consent". In this respect, cl 10 of SEPP 71 provides:
State significant development
(1) Pursuant to section 76A (7) of the Act, development specified in Schedule 2 is declared to be State significant development.
(2) Pursuant to section 76A (9) of the Act, the Minister is the consent authority for State significant development.
15 Although in these proceedings the second Respondent has not sought to argue that the approved development was not relevantly development of land to which SEPP71 applies for the purposes of "tourist facilities" (it has argued that it was not relevantly State significant development because, in terms of the LEP, development for the purposes of a "tourist facility" was an absolutely prohibited purpose of development in respect of the subject land), it nonetheless is incumbent upon the Applicants to establish all elements of their claim to declaratory relief: see Jones v Sutherland Shire Council (1979) 40 LGRA 323 at 327 per Hutley JA:
Where a person seeks a declaration, he has to prove all the facts which are necessary to enable that declaration to be obtained. This means that he takes upon himself to prove all the conditions necessary to be established, including matters which he could require the other party to prove, if he were the defendant.
16 In seeking to establish their claim that the development consent is a legal nullity because the approved development was relevantly a State significant development, the competing cases have commonly proceeded upon two unstated assumptions which are fundamental to the Applicants' claim, namely: -
(i) that it is for this Court to determine for itself whether the approved development was relevantly development for the purposes of " tourist facilities " within the meaning of SEPP71, and
(ii) that the effect of s 76A(7)(a) of the EP&A Act (repeated by cl 10 of SEPP71) declaring the Minister to be the consent authority for the State significant development specified in Schedule 2 to SEPP71 necessarily divested the Council of its function as the " consent authority " nominated by the LEP in respect of the development application to which it purported to grant the development consent.
17 Despite the fundamental importance of these two unstated assumptions, they were not the subject of any argument or debate at the hearing. It may be that without expressly so saying, all parties conceded that the correctness of both assumptions was supported by two recent decisions of the Court of Appeal, namely Chambers v Maclean Shire Council (2003) 126 LGERA 7 and Currey v Sutherland Shire Council (2003) 129 LGERA 223 insofar as they commonly held that a development application made to a body that is not the relevant "consent authority" in terms of the EP&A Act is of no legal effect.
18 In these circumstances, I do not think it necessary for me to closely examine the two assumptions other than what I now have to say in respect of the question of who in the present case was the relevant "consent authority" (this being something that was not discussed in either of the decisions of the Court of Appeal).
19 The statutory functions conferred upon a "consent authority" are of fundamental importance to the operation of Pt 4 of the EP&A Act. Thus, to note some of those functions, all development applications are made to the consent authority (s 78A), any procedural requirements relating to the development application must be undertaken by the consent authority (ss 79, 79A, 79B), the planning evaluation of the development application is undertaken by the consent authority (s 79C) and the development application is determined by the consent authority (s 80).
