No such notice was served upon the owner and occupier of the premises.
20 Clause 34 of the Planning Scheme provided, inter alia:
(1) If an existing building or existing work is such that had it been erected or carried out after the appointed day its erection or carrying out would have been permissible with the consent of the responsible authority or if an existing use of an existing building or existing work would have been permissible with such consent had the building been erected or the work carried out after that date, or if an existing use of land is such that if it had been commenced after that date it would have been permissible with the consent of the responsible authority, the owner or occupier of or any person having an estate or interest in, the building or work or land may apply to the responsible authority for its consent to the retention of the building or work or to the continuance of the existing use of the building, work or land, as the case may be.
Any application under this subclause may be made at any time before service on the applicant of a warning notice or at any time after service of such notice and before the prescribed notice under s 342P of the Act takes effect.
(2) In any case where the application under this clause is made to the responsible authority the operation of a warning notice whether served before or after the making of the application shall be suspended pending the decision of the responsible authority on such application and, in any case where an appeal against the decision of the responsible authority is made as hereinafter provided, the operation of the notice shall be suspended pending the determination of the appeal.
An appeal may be made by the applicant against the decision of the responsible authority under this clause in accordance with the provisions of section 341 of the Act, and the provisions of that section shall extend, mutatis mutandis, to and in respect of any such appeal.
(3) If consent is given under this clause to the retention of the building or work or to the continuance of the existing use of the building, work or land, the responsible authority shall not serve a warning notice, and in the case where any such notice may have been already served, such notice shall cease to have effect."
21 Clauses 35 and 36 of the Planning Scheme provided, inter alia:
"35(1) Notwithstanding the foregoing provisions of this Ordinance, an existing building, the erection of which would have contravened some provision of this Ordinance if it had taken place after the appointed day or had taken place after the appointed day without the consent of the responsible authority, may be altered, enlarged, or extended, or added to by the erection of new buildings, provided -
(a) the responsible authority having regard to the circumstances of the case and the public interest approves the alteration, enlargement, extension or addition unconditionally or subject to conditions;
…
36. The right conferred by this Part of this Ordinance to continue the use of an existing building shall where such building was immediately before the appointed day used for more than one purpose include a right to alter the proportion in which the several parts of such building were used immediately before that day."
22 An application under clause 34 was made by a bank which claimed to have an estate or interest in Nos 4 and 6 Kensington Road, Summer Hill. The application said:
"The Bank is interested in the properties described hereunder and desires consents under Clause 34 of the above Ordinance for the continued use and/or development of the properties as flatettes:-
No 4 Kensington Road, Summer Hill - present owner H R Feather - being parts of Lots 15, 16 and 17 of Section 5.
No 6 Kensington Road, summer Hill - present owner Mrs C M Feather - being parts of Lots 15, 16 and 17 of Section 5."
23 A Works Committee's report which went to the Council for its consideration read as follows:
"Clause 6134. Commonwealth Bank, Dungog. Kensington Road Nos 4 and 6. Approval sought to the continued use of the premises as flatettes. Report by the Town Planner:
'I recommend approval be given to the continued use of these premises as residential buildings.'
Recommendation: That the report be adopted and approval be granted."
24 On 13 October 1953, the Council adopted that part of the Works Committee's report.
25 Subsequently, on 14 October 1953, the Town Clerk wrote to the respondent as follows:
"Replying to your letter of the 23rd ultimo, I wish to advise that the Council offers no objection to the continued use of premises Nos. 4 and 6 Kensington Road, Summer Hill as flatettes."
26 Notwithstanding the Town Clerk's reference to flatettes, it is clear that the Council approved the use of the premises, Nos 4 and 6 Kensington Road, as residential buildings.
27 The consent granted was an effective consent to the existing use of the premises. Part VI of the Planning Scheme makes provision with respect to the making of application for consent and the granting of consent. There is no reason to restrict the provisions of that Part to applications for a new or varied use. In Felt & Textiles of Australia Pty Ltd v Sydney City Council (1954) 19 LGR 238, Sugerman J explained this when he said at 241-2:
" On a consideration together of the provisions of cll.26, 28, 29, 32, 34 and 41 of the Ordinance the responsible authority in my opinion has under cl.34 a discretion to determine whether or not it will grant consent to the retention of an existing building, & c., or the continuance of an existing use, within Column IV in the Table to cl.26, subject, of course, to the appeal to this Court, which is provided for by cl.34(2). Existing column IV buildings and uses, as well as existing Column V buildings and uses, are expressly included within the power of the responsible authority to serve warning notices under the proviso to cl.32. No provision is made for consent to the retention or continuance of a Column V building or use. That the existing building or use should fall within Column IV, and not Column V, is a condition governing the right to apply under cl.34, and not a measure of the responsible authority's discretion thereunder. Even apart from the provisions of cl.41(3), cl.34 itself contains ample indication that the responsible authority is to have a discretion in deciding an application, which, if it is to be brought at all, must relate to a Column IV use; see the reference in sub-cl.(2) to 'the decision of the responsible authority upon such application', and the terms of sub-cl.(3) which import that consent may or may not be given to the retention or continuance of the building or use, which, ex hypothesi , is a Column IV building or use."
