Construction of s 43A
76 The term 'environmental authorisation' was already defined in s 43A. Clearly 'specific environmental authorisation' was added to focus on precise specifics of the authorisation.
77 In short, the effect of the amendments was to narrow the scope of the exemption provided by s 43A to particular actions which were specifically authorised by an existing environmental approval. Therefore, a general authorisation to do an action in an area would not after 2006, qualify as a 'prior authorisation' for the purposes of s 43A of the EPBC Act.
78 That this was the intended effect is confirmed by reference to the Explanatory Memorandum to the Environment and Heritage Legislation Amendment Bill (No. 1) 2006 which said the following in respect of the changes to s 43A (at [53]):
Items 123 to 128 - Section 43A
53. These items amend section 43A of the Act which provides that certain actions which were specifically authorised before the commencement of the Act do not require approval under Part 9 of the Act. The purpose of these amendments is to clarify that in order for section 43A to apply to an action the action must have been authorised under a specific environmental authorisation which relates to that particular action (by reference to acts and matters uniquely associated with that action) and not types, groups, or classes of actions. For example, in relation to an action involving vegetation clearance, an environmental authorisation which authorised all persons, or a class of persons, to undertake vegetation clearance in the general area in which the action is proposed to be taken would not be a specific environmental authorisation for the purposes of section 43A. Further, the amendments clarify that section 43A only applies to an action which was authorised by a specific authorisation before the commencement of the Act, if the relevant authorisation is still in force.
79 For ease of reference the changes made to s 43A by the 2006 Act amendments are shown below in strikethrough (for deletions) and underlining (for additions):
43A Actions with prior authorisation
(1) A person may take an action described in a provision of Part 3 without an approval under Part 9 for the purposes of the provision if:
(a) the action consists of a use of land, sea or seabed; and
(b) the action was specifically authorised under a law of the Commonwealth, a State or a self-governing Territory before the commencement of this Act; and
(b) before the commencement of this Act, the action was authorised by a specific environmental authorisation; and
(c) immediately before the commencement of this Act, no further specific environmental authorisation was necessary to allow the action to be taken lawfully.; and
(d) at the time the action is taken, the specific environmental authorisation continues in force.
(1A) For the purposes of paragraphs (1)(c) and (d), a renewal or extension of a specific environmental authorisation is taken to be a new specific environmental authorisation unless:
(a) the action that is authorised by the authorisation following the renewal or extension is the same as the action that was authorised by the authorisation before the commencement of this Act; and
(b) the renewal or extension could properly be made or given without any further consideration of the environmental impacts of the action.
Note: If a renewal or extension of a specific environmental authorisation is taken to be a new specific environmental authorisation, the condition in paragraph (1)(c) or (d) would not be met.
(2) In this section this Act:
environmental authorisation means an authorisation under a law of the Commonwealth, a State or a self-governing Territory that has either or both of the following objects (whether express or implied):
(a) to protect the environment;
(b) to promote the conservation and ecologically sustainable use of natural resources.
specific environmental authorisation means an environmental authorisation that:
(a) identifies the particular action by reference to acts and matters uniquely associated with that action; or
(b) was issued or granted following a consideration of the particular action by reference to acts and matters uniquely associated with that action.
80 It is evident that the scope of the exemption in s 43A has been narrowed since it was considered in Greentree. In particular, a general authorisation by or under a State law will no longer be sufficient to engage the exemption. It is now necessary for the environmental authorisation under State law to satisfy one of the two limbs of the definition of 'specific environmental authorisation' set out above. Further, as noted, for a prior authorisation exemption to be made out under s 43A of the EPBC Act, it is necessary that all four limbs under s 43A(1) be satisfied.
81 Examining the current form of s 43A(1) in greater detail and turning first to each of the four limbs under s 43A(1) of EPBC Act, the first requirement is s 43A(1)(a) is that 'the action consists of a use of land, sea or seabed'. Section 43A(1)(a) is clearly satisfied on the facts of this case as the Proposed Action consists of a use of land.
82 Section 43A(1)(b) requires that 'before the commencement of this Act, the action was authorised by a specific environmental authorisation'. Ministerial Statement 368 is an authorisation made under the EP WA Act that came about prior to the commencement of the EPBC Act on 16 July 2000. The date of the authorisation of Ministerial Statement 368 is not at issue, rather, its characterisation.
83 Section 43A(1)(c) mandates that 'immediately before the commencement of this Act, no further specific environmental authorisation was necessary to allow the action to be taken lawfully'. This requirement too is argued to be satisfied on the facts of this case because immediately prior to the commencement of the EPBC Act, on 16 July 2000, no further specific environmental authorisation was necessary to allow the Proposed Action to be taken lawfully. In particular, had the Proposed Action hypothetically been taken immediately prior to 16 July 2000, then the only additional authorisation required as a matter of law would have been a subdivision approval from the WAPC, which the applicants argue would not have been an 'environmental authorisation' as defined in s 43A(2) of the EPBC Act, as the former TPD Act was not a law concerning the protection of the environment or the conservation of natural resources.
84 Importantly, the applicants note that the enquiry required by s 43A(1)(c) of the EPBC Act focusses upon a specific point in time, being immediately prior to the commencement of the EPBC Act on 16 July 2000, so the question of whether a further specific environmental authorisation would have been necessary must be viewed in the context of the statutory framework, existing environmental values and environmental science as they stood at that time, as opposed to considering these in a present day context.
85 Section 43A(1)(c) of the EPBC Act incorporates the words 'was necessary'. The applicants say that it only refers to environmental authorisations that would have been mandatory, as opposed to something that would have been optional or something that a given proponent may have sought out of an abundance of caution.
86 On this note, s 38 of the EP WA Act, as it stood immediately prior to the commencement of the EPBC Act, did not impose any mandatory obligation on a proponent to refer a proposal to the EPA for potential assessment and approval under Pt IV of the EP WA Act. It can be noted that at the time of commencement of the EPBC Act s 38 of the EP WA Act was, relevantly, in the following terms:
38. Referrals
(1) A proposal that appears likely, if implemented, to have a significant effect on the environment, or a proposal of a prescribed class -
(a) subject to section 48I, shall, in the case of a proposal other than a proposal under an assessed scheme, be referred in writing to the Authority by a decision-making authority as soon as that proposal comes to the notice of the decision-making authority; and
(b) may be referred in writing to the Authority by -
(i) the proponent; or
(ii) in the case of a proposal other than a proposal under an assessed scheme, any other person.
(2) If it appears to the Minister that there is public concern about the likely effect of a proposal, if implemented, on the environment, the Minister may refer in writing the proposal to the Authority.
(3) The Authority shall, if -
(a) it considers that a proposal is likely, if implemented, to have a significant effect on the environment; and
(b) in the case of a proposal under an assessed scheme, the Authority did not, when it assessed the assessed scheme under Division 3, have sufficient scientific or technical information to enable it to assess the environmental issues raised by that proposal,
or if a proposal is of a prescribed class, require in writing a decision-making authority or proponent to refer in writing the proposal to the Authority within such period as is specified in that requirement.
(3a) In subsections (1) and (3), a reference to a proposal of a prescribed class includes a reference to a proposal of a prescribed class under an assessed scheme.
(4) A decision-making authority or proponent which or who is required under subsection (3) to refer a proposal to the Authority shall comply with that requirement.
(5) Subject to section 46(6), a proposal shall be referred once only to the Authority under this section.
…
87 It cannot therefore be said, the applicants argue, that the Proposed Action, immediately before the commencement of the EPBC Act, 'was required' to be the subject of some further Pt IV of the EP WA Act environmental authorisation, for the purpose of s 43A(1)(c) of the EPBC Act.
88 Section 43A(1)(d) of the EPBC Act requires that 'at the time the action is taken, the specific environmental authorisation continues in force'. This final requirement in s 43A(1) is said to be clearly satisfied on the facts of this case, as Ministerial Statement 368 remains in force.
89 Whether Ministerial Statement 368 is shown to be a 'specific environmental authorisation' of the Proposed Action within the meaning of s 43A requires close regard to the statutory term. As identified above, this is a higher threshold than in Greentree. For convenience, s 43A(2) is set out again where the key terms are defined:
43A Actions with prior authorisation
…
(2) In this Act:
environmental authorisation means an authorisation under a law of the Commonwealth, a State or a self-governing Territory that has either or both of the following objects (whether express or implied):
(a) to protect the environment;
(b) to promote the conservation and ecologically sustainable use of natural resources.
specific environmental authorisation means an environmental authorisation that:
(a) identifies the particular action by reference to acts and matters uniquely associated with that action; or
(b) was issued or granted following a consideration of the particular action by reference to acts and matters uniquely associated with that action.
90 To constitute a 'specific environmental authorisation', Ministerial Statement 368 must satisfy the definition of 'environmental authorisation' and then one of the two sub-definitions to 'specific environmental authorisation'. This is the first hurdle that the applicants' arguments confront. They must demonstrate that Ministerial Statement 368 has, either expressly or impliedly, the object of protecting the environment and/or of promoting the conservation and ecologically sustainable use of natural resources. While I do not need to make a conclusive determination on this issue as I am satisfied even if it were an environmental authorisation, that it was not a specific environmental authorisation, I consider there are difficulties in such a characterisation of what, prima facie, is an urban planning document.
91 From the outset, the Minister has emphasised in written and oral submissions the sole reliance the applicants place on Ministerial Statement 368, described by the Minister as a 'high level planning document'. Ministerial Statement 368 contains no mention of the applicants, of their lots or of their particular development, specifically, the Proposed Act. Further, Ministerial Statement 368 does not make specific reference to the proposed subdivision of and, more importantly, it does not address the proposed clearing of the Subject Land.
92 First, it must be noted that Ministerial Statement 368 is an environmental authorisation granted to the DPUD. The conditions imposed, and commitments undertaken, by operation of Ministerial Statement 368, including those (limited) environmental conditions, are directed at the DPUD, being the 'proponent'. Clause 6-1 requires Ministerial approval for any change of proponent. There is no evidence that the proponent was ever changed. Ministerial Statement 368, therefore, does not authorise any conduct specifically by the applicants.
93 Properly understood, it is clearly a high-level document which contemplates the need for more detailed environmental management planning. Clause 3-2 and cl 5-1 both specify a requirement for the preparation of an Environmental Management Programme.
94 In addition, Ministerial Statement 368 did not authorise the subdivision or clearing of the Subject Land for the purposes of State law. Further authorisation was required under Western Australian law for the subdivision and clearing of the Subject Land and the residential development, being the Proposed Action. Ministerial Statement 368 simply does not descend to any level of sufficient particularity of authorising clearing of the Subject Land. This is problematic given both sub-definitions to 'specific environmental authorisation' contemplate an authorisation of a 'particular act'. The Proposed Action (as defined in these reasons (at [2]) in accordance with the applicants' amended originating application) is not contemplated by Ministerial Statement 368.
95 That further subdivision approval for the Subject Land was needed and granted was made explicit in evidence. It appears that subdivision approval in respect of the Subject Land was in fact granted on 27 February 2015, with later subdivision approval dated 17 October 2016 being granted in respect of a portion of the Subject Land. The applicants' evidence confirms this by referring to the subsequent approval of 17 October 2016 as granting 'approval of the proposed subdivision of portions of Lots 635 and 739 (first stage) including 247 residential lots'. It is also important to note, in respect of both these subdivision approvals, that environmental conditions were imposed. In the 27 February 2015 subdivision approval the following is recorded:
The condition(s) of this approval, with accompanying advice, are:
…
CONDITIONS:
Environmental
12. Prior to the commencement of subdivisional works a Fauna Management Plan including information on relocation of native fauna species is to be prepared and approved to ensure the protection and management of the sites environmental assets with satisfactory arrangements being made for the implementation of the approved plan. (Local Government)
13. Measures being taken to ensure the identification and protection of any vegetation on the site worthy of retention that is not impacted by subdivisional works, prior to commencement of subdivisional works. (Local Government)
14. Prior to commencement of subdivision works, investigation for soil and groundwater contamination is to be carried out to determine if remediation is required. If required, remediation, including validation of remediation, of any contamination identified shall be completed prior to the issuing of titles to the satisfaction of the Western Australian Planning Commission on advice from the Department of Environment Regulation, to ensure that the lots created are suitable for the proposed use. Investigations and remediation are to be carried out in compliance with the Contaminated Sites Act 2003 and current Department of Environment Regulation Contaminated Sites Guidelines.
(Department of Environment Regulation)
96 In the 17 October 2016 subdivision approval the following is recorded:
The condition(s) of this approval, with accompanying advice, are:
…
CONDITIONS:

13. Prior to the commencement of subdivisional works a Fauna Management Plan including information on relocation of native fauna species is to be prepared and approved to ensure the protection and management of the sites environmental assets with satisfactory arrangements being made for the implementation of the approved plan.

14. Measures being taken to ensure the identification and protection of any vegetation on the site worthy of retention that is not impacted by subdivisional works, prior to commencement of subdivisional works. (Local Government)
15. Prior to commencement of subdivision works, investigation for soil and ground water contamination is to be carried out to determine if remediation is required. If required, remediation, including validation of remediation, of any contamination identified shall be completed prior to the issuing of titles to the satisfaction of the Western Australian Planning Commission on advice from the Department of Environment Regulation, to ensure that the lots created are suitable for the proposed use.
Investigations and remediation are to be carried out in compliance with the Contaminated Sites Act 2003 and current Department of Environment Regulation Contaminated Sites Guidelines. (Department of Environment Regulation)
97 This poses further difficulty to the applicants' contention that s 43A(1)(c) is satisfied which requires that 'immediately before the commencement of this Act, no further specific environmental authorisation was necessary to allow the action to be taken lawfully'.
98 The submissions for the applicants also rely on a letter dated 5 May 1994, which was described as an appendix to EPA Bulletin 746. To say, as this letter does, that 'decisions on the use of bushland areas … should be made through the planning process both at the State and local level' also does not extend to the particularity of authorising clearing of the Subject Land, or authorise any activity by the applicants upon the Subject Land. It is plainly not a specific prior authorisation of the kind that would be necessary to attract the exemption in s 43A.
99 Finally, it is necessary to consider one further argument advanced by the applicants. As the applicants observe, it is trite law that that in the absence of some clear statement to the contrary, an Act will be assumed not to have retrospective operation: see Maxwell v Murphy (1957) 96 CLR 261 (at 267). See also other cases cited in Pearce and Geddes, Statutory Interpretation in Australia (9th ed) (at 357-358). It is contended that legislation only operates retrospectively if it provides that rights and obligations are changed with effect prior to the commencement of the legislation: Pearce and Geddes (at 360).
100 The applicants contend that a question arises as to whether the EPBC Act operates to change retrospectively the rights that are conferred by the Urban Deferred zoning of the Subject Land as it stood prior to the commencement of the EPBC Act. The applicants say that there is no clear statement in the EPBC Act that it is intended to affect the rights that attach to the Subject Land as a result of the Urban Deferred zoning of the land. The applicants contend the EPBC Act should not be interpreted in a manner that will defeat the rights of a landowner arising under the existing zoning of the Subject Land, where no further environmental authorisation was required for the development of the land for urban purposes.
101 As to the presumption against retrospectivity, there is no ambiguity in s 43A with respect to which that interpretative aid could assist the applicants in the present case. Indeed, there is no question of retrospectivity. All legislation impinges on existing rights and obligations. Conduct that could formerly be engaged in will have to be modified to conform with a new law: see Chang v Laidley Shire Council (2007) 234 CLR 1 (at [113]). It cannot therefore be said that legislation having this effect is retrospective because it operates as all legislation does. Legislation only operates retrospectively if it provides that rights and obligations are changed with effect prior to the commencement of the legislation. The EPBC Act relevantly established a new regime moving forward. Section 43A may be seen as creating an exemption and the 2006 Act modifying the exemption. The creation of an exemption in the case of past specific approval of the limited kind referred to in s 43A does not amount to retrospectivity. It is, rather, a limited saving from the prospective operation of the EPBC Act. It is the Proposed Action with which this case is relevantly concerned. Had the development been completed before the introduction of the 2006 amendment to the EPBC Act, the EPBC Act would have had no relevant effect.
