63 Proper consideration of a relevant matter does not demand factual correctness. It is wrong to equate relevancy with factual correctness. A wrong assessment of the consideration the decision maker takes into account is not a reviewable error of law."
20 The need for proper consideration has been pointed out in many cases collected in the reasons for judgment of Spigelman CJ in Bruce v Cole (1998) 45 NSWLR 163 at 185-186. It was expressed by Gummow J in Khan v Minister for Immigration and Ethnic Affairs (1987) 14 ALD 291 as follows:
"[W]hat was required of the decision maker…was that in considering all relevant material placed before him he give proper, genuine and realistic consideration to the merits of the case and be ready in a proper case to depart from any applicable policy…The assertion by a decision maker that he has acted in this fashion will not necessarily conclude the matter; the question will remain whether the merits have been given consideration in any real sense."
21 It became conventional to say that mandatory consideration of a relevant matter must be "proper, genuine and realistic", accompanied by a caution that those epithets had to be applied cautiously lest they encourage a slide into impermissible merit review. More recently, however, the Court of Appeal has said that it is preferable to avoid using the formula "proper, genuine and realistic", or similar descriptive formulae, because their use is fraught with the danger of a slide into impermissible merit review; but that the relevant matter must be more than merely adverted to or given mere lip service: Anderson v Director-General Department of Environment and Climate Change [2008] NSWCA 337, 163 LGERA 400 at [51]-[58].
22 Manifest unreasonableness as a ground of judicial review conveys the idea that a court should not lightly interfere with administrative decision-making. The test is not whether the Court considers the administrative decision is unreasonable. The test is whether the Court considers the decision is so unreasonable that no reasonable body could have come to it: Notaras at [124]; Minister for Immigration and Citizenship v SZMDS [2010] HCA 16 at [123]. To give grossly inadequate weight to a matter of some importance can only qualify as a ground of judicial review if it satisfies the test of manifest unreasonableness as applied to the exercise of power: Minister for Planning v Walker at [35] quoting Notaras at [119] which cited Belmorgan Property Development Pty Ltd v GPT Re Ltd [2007] NSWCA 171, 153 LGERA 450 at [76]-[78].
23 There may be occasions when failure to take into account a relevant consideration overlaps with manifest unreasonableness: Williams v Minister for the Environment and Heritage [2003] FCA 535 at [32] (Wilcox J).
BACKGROUND
24 Sandon Point comprises 53 hectares of coastal plain located approximately 14 kilometres north of Wollongong City. The development site is located on the western side of Sandon Point and covers approximately 23.35 hectares.
Part 3A of the EPA Act Applies
25 In 2002, the (then) Minister issued a direction under the EPA Act for a Commission of Inquiry (COI) to be held into the preferred use of land at Sandon Point, including land within the development site. The COI 2003 report made 80 findings and recommendations concerning the development of land within the area considered.
26 In 2005, the (then) Minister appointed Charles Hill of Planning Workshop Australia to provide an independent review of the COI's findings and recommendations. In his 2005 report, Mr Hill recommended "a larger development footprint" and "that rezoning for development should be allowed on terms that more than 60 per cent should be left as open space and brought mostly into public ownership; and that some hectares towards the western boundary should be deemed suitable for medium density residential development, including aged care facilities": Walker at [18].
27 On 12 December 2005, the Department of Planning advised Wollongong City Council that the Minister had agreed to consider Sandon Point as a potential State Significant Site under the State Environmental Planning Policy (Major Development) 2005 (Major Projects SEPP) and that it was expected a concept plan would be lodged under Pt 3A of the EPA Act.
28 On 2 March 2006, HLA Envirosciences Pty Ltd, on behalf of Stockland and Anglican Retirement Villages, wrote to the Department of Planning requesting the Minister to declare that the proposed development at Sandon Point was a "major project" within cl 13 of Schedule 1 to the Major Projects SEPP, to which Part 3A applied: s 75B. That clause, as it then stood, concerned residential, commercial or retail projects with a capital investment value of more than $50 million.
29 On 2 April 2006 the Minister made a declaration, having formed the opinion for the purposes of cl 6 of the Major Projects SEPP that the proposed development fell within cl 13 of Schedule 1. As a result, the Minister became the approval authority: s 75D.
30 The Minister authorised Stockland and Anglican Retirement Villages to submit a concept plan for the site, in accordance with s 75M. In turn, the Director-General directed Stockland and Anglican Retirement Villages to prepare a study to justify the inclusion of Sandon Point as a State Significant Site under the Major Projects SEPP.
Concept Plan Approval
31 On 19 June 2006 Stockland and Anglican Retirement Villages submitted a concept plan for residential subdivision and the development of a residential facility. On 21 December 2006 the Minister approved this concept plan under s 75O of the EPA Act.
32 A challenge to the Minister's approval of the concept plan succeeded at first instance in Walker v Minister for Planning [2007] NSWLEC 741, 157 LGERA 124 (November 2007). I held that the approval was invalid as the Minister failed to have regard to the principles of ecologically sustainable development by failing to consider whether the impacts of climate change would lead to an increased flood risk on this flood-constrained coastal plain project. This decision was successfully appealed in Minister for Planning v Walker [2008] NSWCA 224, 161 LGERA 423 (September 2008). However, the Court of Appeal supported much of my reasoning and conclusions, as I discussed in Aldous v Greater Taree City Council [2009] NSWLEC 17, 167 LGERA 13 at [25]-[32]. The Court of Appeal held that it is mandatory that the Minister consider the public interest when determining a concept plan approval application under Pt 3A: at [39], [65], [66]. The majority (the third member of the court expressing no opinion) held:
