(a) The EPA Act and Regulation
7Section 76A(1) of the EPA Act is in the following terms:
"76A Development that needs consent
(1) GeneralIf an environmental planning instrument provides that specified development may not be carried out except with development consent, a person must not carry the development out on land to which the provision applies unless:
(a) such a consent has been obtained and is in force, and
(b) the development is carried out in accordance with the consent and the instrument."
8Division 2 of Pt 4 of the EPA Act sets out the steps to be taken to obtain development consent when it is required. Section 78A provides for the making of an application for development consent whilst ss 79-79C provide for the procedures to be adopted by the consent authority in considering whether to grant consent.
9Section 80 of the EPA Act deals with the determination of an application for development consent. So far as relevant it provides as follows:
"80 Determination
(1) GeneralA consent authority is to determine a development application by:
(a) granting consent to the application, either unconditionally or subject to conditions, or
(b) refusing consent to the application.
(2) Despite subsection (1), the consent authority must refuse an application for development, being the subdivision of land, that would, if carried out, result in a contravention of this Act, an environmental planning instrument or the regulations, whether arising in relation to that or any other development.
(3) 'Deferred commencement' consentA development consent may be granted subject to a condition that the consent is not to operate until the applicant satisfies the consent authority, in accordance with the regulations, as to any matter specified in the condition. Nothing in this Act prevents a person from doing such things as may be necessary to comply with the condition."
10Section 81 of the EPA Act provides for the notification of the grant of consent. It is in the following terms:
"81 Post-determination notification
(1) The consent authority must, in accordance with the regulations, notify its determination of a development application to:
(a) the applicant, and
(b) in the case of a development application for consent to carry out designated development, each person who made a submission under section 79 (5), and
(c) such other persons as are required by the regulations to be notified of the determination of the development application.
(2) If the consent authority is not the council, the consent authority must notify the council of its determination.
(3) In the case of a development application for consent to carry out designated development, the consent authority must also notify each person who made a submission under section 79 (5) by way of objection of the person's rights to appeal against the determination and of the applicant's rights to appeal against the determination."
11Section 83 of the EPA Act provides for the date from which consent operates. Sections 83(1) and 83(2) are in the following terms:
"83 Date from which consent operates
(1) Subject to subsections (2) and (3), if a determination is made by the granting of consent, the consent becomes effective and operates from:
(a) except as provided in paragraph (b)-the date that is endorsed on the notice given to the applicant in accordance with section 81 (1) of the determination of the development application or under section 82D(4), or
(b) in the case of designated development to which an objection has been made in accordance with section 79 (5):
(i) if consent was granted under section 80 (6) or (7) following the holding of a review that includes a public hearing by the Planning Assessment Commission-the date that is endorsed on the notice of the determination of the development application given to the applicant in accordance with section 81 (1), or
(ii) in any other case-the expiration of 28 days from the date that is endorsed on the notice of the determination of the development application given to the applicant in accordance with section 81 (1).
(2) Subject to subsection (3), if a determination is made by the granting of consent or the granting of consent subject to conditions, and an appeal has been made under section 97(1) or 98, the consent:
(a) ceases to be, or does not become, effective pursuant to subsection (1), and
(b) becomes effective and operates from the date of the determination of that appeal, except where that decision is to refuse development consent."
12Section 82A of the EPA Act provides that, subject to certain exceptions when the consent authority is a Council, an applicant may request a review of the decision. Section 97 provides for a right of appeal against the determination of the consent authority within 6 months after notice has been received in accordance with the Regulation, or it is determined in accordance with the time specified in the Regulation that the consent authority has refused consent.
13Clause 100 of the Regulation, made under the EPA Act, provides for the form of notification of the consent. Subclauses 100(1) and 100(4) of the Regulation are relevant for the purpose of the proceedings. They are in the following terms:
"100(1) For the purposes of section 81 (1) of the Act, a notice of the determination of a development application must contain the following information:
(a) whether the application has been granted or refused,
(b) if the application has been granted, the terms of any conditions (including conditions prescribed under section 80A (11) of the Act) on which it has been granted,
(c) if the application has been refused, or granted subject to conditions (other than conditions prescribed under section 80A (11) of the Act), the consent authority's reasons for the refusal or for the imposition of those conditions,
(c1) whether the applicant has the right to request a review of the determination under section 82A of the Act,
...
(d) the date on which the determination was made,
(e) the date from which any development consent that is granted operates,
...
(4) In the case of a development consent granted subject to a condition that the consent is not to operate until the applicant satisfies the consent authority, or a person specified by the consent authority, as to any matter specified in the condition:
(a) the date from which the consent operates must not be endorsed on the notice of determination, and
(b) if the applicant satisfies the consent authority, or person, as to the matter, the consent authority must give notice to the applicant of the date from which the consent operates."
14Clause 102 of the Regulation provides for notification of the determination of consent of an application for development consent to be sent to those persons entitled to receive it within 14 days of the date of determination. The Regulation requires that for the purposes of s 81(1)(c) of the EPA Act any person who has made a submission in respect of the application for development consent is required to be notified.
15Section 101 of the EPA Act provides as follows:
"101 Validity of development consents and complying development certificates
If public notice of the granting of a consent or a complying development certificate is given in accordance with the regulations by a consent authority or an accredited certifier, the validity of the consent or certificate cannot be questioned in any legal proceedings except those commenced in the Court by any person at any time before the expiration of 3 months from the date on which public notice was so given."
