Consideration
34 In my opinion, the reference in s 75(1) of the unamended Act to 'for the purposes of Part 4' means no more than the development control mechanisms in that Part were applicable, except where the subject matter was not amenable to those controls. It must be kept steadily in mind that when the LEP was made, this section was in the Act. It must be taken to have informed the meaning and content of the instrument. It is difficult to understand how s 75(1) could not have affected the meaning of 'development' within s 4 when 'development' is pivotal to the operation of Part 4 of the Act.
35 It should be noted in passing that the appellant does not submit that cl 23 of the LEP is ultra vires. Rather, Mr Hale submits that cl 23 regulates 'development' within its own terms. He submits however that parts of cl 23 may be ineffective so as to require development consent. In my opinion, the submission gives no recognition to s 75(1) or subpara (f) of s 26 of the unamended Act.
36 The transposition of the words in s 75(1) of the unamended Act to subpara (f) of the definition of development in the amended Act did not, in my view, alter the outcome of cl 23 of the LEP.
37 The parties are in dispute as to whether the LEP operates in an ambulatory fashion. The appellant submits that the words in the instrument must have the meaning that they were intended to have at the time the LEP was made. It is submitted that to hold otherwise would defeat the consultation and public participation processes inherent in the making of the LEP. Those provisions in the Act would, in effect, be bypassed.
38 There are two answers to this proposition. First, while the public consultation process is important, the process is not, as Mr Ayling notes, sacrosanct. For example, an LEP may be substantially affected by a decision of the Minister. Moreover, State Environmental Planning Policies, the highest form of planning instruments, do not have to be preceded by any public participation.
39 The second answer is one of manifest inconvenience. If the appellant's submission is correct, then in order to facilitate the amendments made to the Act, many hundreds of LEPs would have to be amended.
40 However, because of the view I take as to the effect of s 75(1) of the unamended Act and subpara (f) of the definition of development in the amended Act, it is unnecessary to determine the ambulatory nature of the LEP and the application of Birch v Allen (1942) 65 CLR 621.
