HEADNOTE

[This headnote is not to be read as part of the judgment]

The respondent, Byron Shire Council ("the Council"), was both the development consent authority and the water and sewerage authority for the Byron Shire. In mid-2000, it assessed that there was spare capacity within the West Byron Sewage Treatment Plant and resolved to allocate that capacity to new developments.

On 6 February 2001 the appellant, Dansar Pty Ltd, lodged an application for approval of the residential development of a property owned by it. In May 2001 there was a deemed refusal of that application and in August 2001 Dansar appealed from that deemed refusal. That appeal was dismissed by the Land and Environment Court in March 2002. In October 2002 Dansar lodged new development applications for the same development. Those applications were approved in June 2005.

In 2007, Dansar commenced proceedings against the Council alleging that the latter had breached a duty of care owed to Dansar, and claiming damages for economic loss suffered as a result of delay in approving its development application. Dansar claimed that but for that breach of duty it would have been allocated the required sewerage capacity and received development approval at some time between December 2001 and February 2002. By judgment of 30 January 2013, McCallum J in the Common Law Division held that the Council did not owe the posited duty of care and entered judgment for the Council.

Held (Meagher and Leeming JJA, dismissing the appeal; Macfarlan JA dissenting):

(1) The existence and content of any duty of care must be determined prospectively and by reference to the statutory context and the positions occupied by the parties in that context ([108]-[110], [158]-[159]).

Sullivan v Moody [2001] HCA 59; 207 CLR 562, CAL No 14 Pty Ltd v Motor Accidents Insurance Board [2009] HCA 47; 239 CLR 390, Perre v Apand Pty Ltd [1999] HCA 36; 198 CLR 180, Graham Barclay Oysters Pty Ltd v Ryan [2002] HCA 54; 211 CLR 540, Stuart v Kirkland-Veenstra [2009] HCA 15; 237 CLR 215, Caltex Refineries (Qld) Pty Ltd v Stavar [2009] NSWCA 258; 75 NSWLR 649, considered.

(2) Where it is said that a public authority owes a duty of care, it is necessary to identify the function or power, the performance or exercise of which is the subject matter of the alleged duty, and to address whether the existence of that duty would give rise to inconsistent obligations or conflicting claims upon the exercise of the power ([159]).

(3) The asserted duty of care is incompatible with the Council's unconstrained exercise of its statutory functions and obligations. In determining whether to increase the permanent load on the treatment works by the amount of capacity required for the appellant's development, the Council was required to give paramount consideration to the safety and continued operation of the treatment facilities, maintaining public health and protecting the environment. That obligation and the interests to which the Council was to have regard are incompatible with the existence of the asserted private law duty of care ([161]).

(4) That incompatibility is not avoided by seeking to restrict the content of the duty by reference to "mechanical" tasks of allocation ([162]). The Council's decision in January 2002 to adhere to the methodology which it had adopted in mid-2000 was not "mechanical" and required a judgment as to whether that methodology and the assumptions and calculations which informed it should be applied when considering Dansar's development ([162]).

Sullivan v Moody [2001] HCA 59; 207 CLR 562, applied.

(5) There was no reliance or assumption of responsibility, and to that extent no relevant vulnerability ([171]-[177]). At no time was Dansar relying on any express or implied assurance from the Council that it would allocate available capacity in a particular way and exercise reasonable care in doing so ([176]). The appellant had the assistance of expert town planning advice. It also had access to officers and staff of the Council, to the public deliberations and resolutions of the Council and to reports presented at those meetings ([173]).

Tepko Pty Ltd v Water Board [2001] HCA 19; 206 CLR 1, Mutual Life & Citizens' Assurance Co Ltd v Evatt [1968] HCA 74; 122 CLR 556, Perre v Apand Pty Ltd [1999] HCA 36; 198 CLR 180, Woolcock Street Investments Pty Ltd v CDG Pty Ltd [2004] HCA 16; 216 CLR 515, considered.

(6) The appellant had no right or entitlement to have any further load committed to the sewerage system. Nor did it have any right or interest, the enjoyment of which depended on the exercise of care by the Council or the existence of which depended on the exercise of care by the Council in the performance of a function that it was obliged to undertake ([179]-[180]). In that respect, the position is to be contrasted with Caltex Oil (Australia) Pty Ltd v The Dredge "Willemstad" [1976] HCA 65; 136 CLR 529, Hill v Van Erp [1997] HCA 9; 188 CLR 159 and Perre v Apand Pty Ltd [1999] HCA 36; 198 CLR 180.

(7) (Per Macfarlan JA, dissenting) The Council was subject to a common law duty of care in the operational task of allocating to developments for which approval was sought the sewerage capacity that it had determined was available and should be allocated to development applicants in order of receipt of application ([73], [83], [85]-[87]). There is no reason why a statutory authority such as the Council may not be subject to specific duties of care related to aspects of its functions that do not involve matters of judgment, opinion or public policy ([69]).

Avenhouse v Hornsby Shire Council (1998) 44 NSWLR 1, Armidale City Council v Alec Finlayson Pty Ltd [1999] FCA 330; 104 LGERA 9 and Western District Developments Pty Ltd v Baulkham Hills Shire Council [2009] NSWCA 283; 75 NSWLR 706, followed.

Dictum of Mason J in Sutherland Shire Council v Heyman [1985] HCA 41; 157 CLR 424 at 469, applied.

Judgment

MACFARLAN JA: In 1997 the respondent Council, which is both the development consent authority and water and sewerage authority for the Byron Shire, resolved to limit the number of new developments it approved in the area, due to the limited capacity of its two sewerage treatment plants. In September 2000, Mr John Vaughan, the principal of Dansar Pty Ltd (the appellant), gave instructions for the preparation of an application by Dansar to the Council for approval of the residential development of a property owned by it. Mr Vaughan was aware of the Shire's limited sewerage capacity but believed that the Council would allocate Dansar part of the available capacity for its development.

Dansar's development application was lodged with the Council on 6 February 2001 but was only approved (by then in an amended form) on 20 June 2005.

Dansar commenced the present proceedings in 2007 claiming damages from the Council for the breach by it of a common law duty of care that it owed to Dansar. Dansar alleged, and continues to allege, that the delay in approval was largely caused by the Council failing to exercise reasonable care in carrying out the mechanical task of allocating the spare capacity which it had determined should be allocated to new developments. Dansar contended that if the Council had not acted negligently, it would have realised that capacity was available to allocate to Dansar, would have made such an allocation and would have approved the development application much earlier than occurred, with Dansar thereby avoiding the financial loss it suffered as a result of the delay.

The proceedings were heard by McCallum J sitting in the Common Law Division. By judgment of 30 January 2013, her Honour found that the Council did not owe the asserted duty of care to Dansar and directed the entry of judgment for the Council ([2013] NSWSC 17).

On appeal, Dansar challenged that finding and contended that this Court should find that the Council both owed the alleged duty of care and breached it. The parties agreed that if the Court found for Dansar on liability, questions of causation and quantum of damages should be remitted to the Common Law Division for determination.

For the reasons that appear below, I consider that the alleged duty was both owed and breached and that the Council did not demonstrate that any of the statutory defences upon which it relied (Civil Liability Act2002 (NSW) ss 43, 43A and 44) were applicable. As a result, the appeal should be allowed and the proceedings remitted to the Common Law Division.

RELEVANT STATUTORY AND OTHER PROVISIONS

Environmental Planning and Assessment Act 1979 (NSW)

Section 76A of the Environmental Planning and Assessment Act ("EPAA") prohibits the development of land without consent where, as in the case of Dansar's proposed development, an environmental planning instrument requires development consent to be obtained. Section 78A permits a person to apply to a consent authority, in this case the Council, for consent to carry out a development. The consent authority is required to consider the matters identified in s 79C in evaluating the application, including the provisions of a relevant environmental planning instrument.

Local Government Act 1993 (NSW)

Section 68 of the Local Government Act ("LGA") prohibits the carrying out of sewerage work and the connection of private drains or sewers to public drains or sewers unless an approval is obtained from the relevant council, here the respondent Council. In determining an application, the council is to consider, inter alia, protection of the environment and of public health, safety and convenience (see s 89). Section 78A(3) of the EPAA permits an application for such approval to be made in a relevant development application lodged with the same council under the EPAA.

Section 176 of the LGA confers a right of appeal to the Land and Environment Court ("LEC") on an applicant who is dissatisfied with the determination of an application for approval concerning sewerage works. The LEC has a discretion on such an appeal to award compensation to an applicant for approval, for any expense incurred in consequence of a council's refusal to grant, or delay in granting, an approval:

"if the Court considers that the council would not have acted in the way it did but for the fact that it was unduly influenced by vexatious or unmeritorious submissions made by members of the public or that the council has acted vexatiously" (see s 179).

Byron Local Environmental Plan 1988

Clause 45(1) of the Byron Local Environmental Plan ("the LEP") provides:

"45(1) The Council shall not consent to the carrying out of development on any land to which this plan applies unless it is satisfied that prior adequate arrangements have been made for the provision of sewerage, drainage and water services to the land".

Civil Liability Act 2002 (NSW)

Sections 43 and 43A of the Civil Liability Act ("CLA") are in the following terms:

"43 Proceedings against public or other authorities based on breach of statutory duty

(1) This section applies to proceedings for civil liability to which this Part applies to the extent that the liability is based on a breach of a statutory duty by a public or other authority in connection with the exercise of or a failure to exercise a function of the authority.

(2) For the purposes of any such proceedings, an act or omission of the authority does not constitute a breach of statutory duty unless the act or omission was in the circumstances so unreasonable that no authority having the functions of the authority in question could properly consider the act or omission to be a reasonable exercise of its functions.

(3) In the case of a function of a public or other authority to prohibit or regulate an activity, this section applies in addition to section 44.

43A Proceedings against public or other authorities for the exercise of special statutory powers

(1) This section applies to proceedings for civil liability to which this Part applies to the extent that the liability is based on a public or other authority's exercise of, or failure to exercise, a special statutory power conferred on the authority.

(2) A special statutory power is a power:

(a) that is conferred by or under a statute, and

(b) that is of a kind that persons generally are not authorised to exercise without specific statutory authority.

(3) For the purposes of any such proceedings, any act or omission involving an exercise of, or failure to exercise, a special statutory power does not give rise to civil liability unless the act or omission was in the circumstances so unreasonable that no authority having the special statutory power in question could properly consider the act or omission to be a reasonable exercise of, or failure to exercise, its power.

(4) In the case of a special statutory power of a public or other authority to prohibit or regulate an activity, this section applies in addition to section 44."

Section 44 of the CLA provides that a public authority such as the Council is not liable for a failure to exercise or to consider exercising any regulatory function if the authority could not have been required to exercise the function in proceedings instituted by the plaintiff.

THE FACTUAL CIRCUMSTANCES

Following the limitation on new developments that the Council imposed in 1997, interim upgrade works were undertaken to improve the Byron Bay area's sewerage capacity.

In mid-2000, an officer in the Council's Engineering Department, Mr Ian Cook, calculated the sewerage capacity of the West Byron Sewerage Treatment Plant (being that which is relevant to Dansar's land) (the "West Byron STP") available for allocation by the Council. He derived a figure of 371 EPs which was converted by Council staff to 92.4 ETs. An "ET" (meaning "equivalent tenement") is a standard measure used to assess the impact of a property on the sewerage system. An "EP" (meaning "equivalent person") is a standard unit of sewerage usage based on the usage of a typical person in a residential setting. Council staff used a ratio of four EPs to one ET in making the conversion. Subsequent documents and also submissions before this Court usually referred to the not materially different figure of 92.75 ETs which I shall use.

At its meeting on 19 September 2000, the Council noted that the West Byron STP had an unused capacity of 371 EPs available for allocation to applicants for development approval.

Dansar lodged its development application with the Council on 6 February 2001, after Mr Vaughan of Dansar had been advised by the Mayor of Byron Bay that there was sewerage capacity available to cover the development.

In a memorandum of 27 February 2001 to the Council's General Manager and others, its Senior Development Engineer, Mr Bob Hanby, said that 32.14 ETs of the 92.75 ETs previously identified spare capacity of the West Byron STP had been allocated to various approved development applications and that the allocations required to satisfy further applications that had been lodged with Council exceeded the balance of the spare capacity. He said that it was therefore necessary "that a protocol be put in place with regard to allocation of the remaining ETs and further acceptance of Development Applications". It is clear that the allocations made and to be made did not include that required for Dansar's development.

These figures were repeated by the Council's General Manager, Ms Robyn Read, in a memorandum of 28 February 2001 to all councillors. Ms Read concluded that there was "no remaining spare capacity in the West Byron STP assuming the success of a large percentage of lodged DAs". The Mayor showed Mr Vaughan a copy of this memorandum the following day. What he said indicated that Dansar's development was one of those to which the previously identified spare capacity had been or would be allocated. Further communications with Council representatives in the following months confirmed Mr Vaughan's belief that this was so.

On 1 March 2001 the Mayor issued a media release stating that the development applications that the Council was then processing would consume the remaining capacity of the West Byron STP and that "any spare capacity that emerges because of the failure of current development applications will be allocated on the basis of date of receipt". The Council passed a resolution to this effect on 24 April 2001. Mr Vaughan read the press release and also a notice to the same effect posted at the Council's offices.

By memorandum of 14 August 2001, Council staff recommended that the Council defer a decision on Dansar's development application for two months to allow for the submission of a revised proposal addressing various concerns set out in the report. None of those concerns related to sewerage. The Council so resolved on that day.

On 31 August 2001, Dansar lodged with the LEC an appeal against the "deemed refusal" of its development application which occurred by reason of the Council not having determined the application within the period prescribed by the regulations (see s 82 EPAA). That deemed refusal did not preclude the Council thereafter considering and determining the application (ibid).

In a memorandum presented to the Council meeting of 28 August 2001, Council staff noted that there were sufficient ETs to allocate to development applications lodged prior to 6 March 2001.

In October 2001 Dansar lodged with the Council amended plans for its development application.

On 2 November 2001 the Council filed in Dansar's LEC proceedings a "Draft Statement of Issues". The first two issues were stated to be:

"1.1 Whether adequate arrangements can be made for the provision of services to the proposed development in accordance with clause 45 of the Byron Local Environmental Plan 1988.

1.2 Whether the proposal can be approved having regard to the inability to make prior adequate arrangements to the satisfaction of Council for the disposal of sewage".

An internal Council document of 18 December 2001 referred to the Dansar development application as requiring, in its original form, 11.6 ETs and 12.4 ETs in its amended form.

By a memorandum of 18 December 2001 Council officers recommended the refusal of Dansar's development application for a number of reasons, the first of which was as follows:

"The proposed development exceeds the available additional loading on sewerage services, and therefore prior adequate arrangements have not been made in accordance with Clause 45 of the Byron Local Environmental Plan 1988".

The memorandum included the following discussion on that topic:

"The calculation of the loading on the sewerage system proposed by this development is as follows:

11 x 2 bedroom units @ 0.7 ET / unit

= 7.7 ET

6 x 3 bedroom units @ 0.95 ET / unit

= 5.7 ET

Total

= 13.4 ET

The additional loading [being additional to the standard 1.0 applicable to the undeveloped site] created by the proposed development is 12.4 ET. There is insufficient capacity available from Council's sewerage infrastructure for the subject development. A separate report is to be presented to the Committee for consideration in this regard. In this regard, the application has not made prior adequate arrangements for the provision of sewerage services to the land as required by Clause 45 of Byron LEP 1988. Additionally the original application was for 11.6 ET. It is not reasonable that the applicant now apply for additional 'spare' ET. Any future allocation, which may become available, should be limited to 11.6 ET".

At its meeting on 18 December 2001, the Council resolved to defer consideration of Dansar's development application and to invite it to amend the application to address a number of points, not including any concerning sewerage. The resolution also stated that "Council recognises that DA 10.2001.64.1 [Dansar's application of 6 February 2001] was included in the pre-6 March 2001 ET allocation". At an extraordinary meeting on 29 January 2002, the Council however rescinded this aspect of its resolution.

A report dated 18 December 2001 prepared by Council staff and dealing with "spare capacity - West Byron sewerage treatment plant" recorded that only 5.073 ETs of the available capacity of 92.75 ETs remained unallocated. It was said that those allocations did not include any allocation for Dansar's development application, which required 11.6 ETs. The report said that there was only 0.943 ET available for Dansar. It noted that further ETs might become available if a development application by Aquarius Backpackers was refused.

The Council's Final Statement of Issues dated 13 February 2002, filed in the LEC proceedings, contained the same first two issues concerning sewerage as included in the draft (as to which, see [24] above).

On 15 February 2002 Mr Phil Warner, the Council's Acting Director of Water and Waste Services, advised councillors that recent sewage flows for Byron Bay showed significant unanticipated growth and indicated that further technical work was being commissioned "to verify the data and suggest appropriate next steps".

Appended to the memorandum was a note from the General Manager which included a statement that "under no circumstances should there be a re-allocation of any ETs that are released through failed court cases, etc". This statement was not contained in what appears to be the final version dated 1 March 2002 of the memorandum and its appended note. In any event, it did not suggest that the identified spare capacity of 92.75 ETs should not remain allocated to those developments to which it had been allocated and which continued to require it.

In his Statement of Evidence for use at the LEC hearing in March 2002, Mr Warner supported the Council's decision to refuse Dansar's development application "as the proposal will place an additional sewage load, in excess of the current and committed loads of 10,395 EP (Equivalent Persons) on the West Byron Sewage Treatment Plant. This plant does not have spare sewage treatment capacity to cater for this additional load". Mr Warner did not say that the spare capacity of 92.75 ETs previously identified as available for allocation should no longer be allocated. Rather, he was saying that Dansar's development could not be accommodated within that total capacity (of 10,395 EPs) because it was already committed. The evidence before the primary judge indicates that this was an erroneous proposition because, contrary to the apparent belief of Council officers, the part of that capacity that had previously been identified as "spare" (92.75 ETs) had not, with due care, been allocated to developments that required it (see [39] - [41] below).

Similarly, in submissions to the LEC on 11 March 2002, the solicitor for the Council opposed Dansar's appeal on the basis, inter alia, that there was insufficient of the 92.75 ETs spare capacity remaining to satisfy the sewerage need for Dansar's development.

In his judgment of 15 March 2002, Commissioner Hoffman of the LEC stated that the parties before him were agreed that one of the two principal issues on the appeal before him was that concerning sewerage identified in [24] above. The Commissioner dismissed the appeal against the deemed decision to refuse the development application. He concluded that sewerage capacity was not available, there being insufficient of the spare capacity of "92 ETs" remaining available for Dansar's development.

A memorandum dated 27 March 2003 from the then General Manager of the Council, Ms Pamela Westing, to councillors and the "Executive Team" stated that allocation of sewerage capacity to development applications would "continue to be made on the basis of a total spare capacity of 92.75 ET, as advised to Council by the then General Manager on 28 February 2001".

Dansar's prospects of obtaining development approval finally changed when, in a letter of 29 April 2004 to Mr Vaughan of Dansar, Ms Westing stated:

" ... A report presenting the issue to Council is scheduled to go to Council's Ordinary Meeting on 11 May 2004. The availability of ETs from the original 92.75 determined in March 2001 is a result of the outcome of various matters before the Land and Environment Court. The report to Council will outline the issues and the options for allocating this capacity. If Council resolves to continue its current process, there will be sufficient ETs available for your development application should you choose to lodge [a] S82A review request, or an appeal to the Land and Environment Court".

The Council passed a resolution to this effect on 11 May 2004 and, by letter of 20 May 2004, the Acting Director of Water and Waste Services of the Council advised Mr Vaughan that 10.5 ETs of the spare sewerage capacity had been reserved for Dansar's development. This was sufficient to satisfy its development's requirements for sewerage.

After further dealings between Dansar and the Council, the Council approved Dansar's amended development application on 20 June 2005.

The available capacity of the West Byron Sewerage Treatment Plant

It was common ground on the appeal that, at all material times, sufficient of the 92.75 ETs total spare capacity referred to above remained available to accommodate Dansar's proposed development application. The Council's position in this respect on appeal and at first instance was confirmed by a letter tendered on appeal. The letter, from Dansar's solicitors to the Council's solicitors, included the following:

"We confirm that you have advised us that your position is that it has never been the Council's case, and it will not be argued on appeal, that ETs were not available for the Dansar application, if the allocations from the pool of 92.75 ETs had been correctly identified and tallied" (Exhibit A).

The nature of the Council officers' errors which led to the Council acting, for a considerable period, on the basis that there was insufficient of the total spare capacity of 92.75 ETs available to accommodate Dansar's proposed development were identified in a schedule provided by Dansar to the Court on appeal. It is unnecessary to state more of the detail of these errors than the following, as the fact that they were made and their effect was a matter of agreement between the parties.

1.8 ETs continued to be allocated in respect of a development application by one Roberts after the application was withdrawn.
1.6 ETs continued to be allocated in respect of a development application by P W O'Connor after the application was approved without any ET requirements.
A standard credit of 1.0 ET per site should have been, but was not, given in respect of a development by C Lonergan and Associates.
3.93 ETs were allocated in respect of a development by one Ahern when no allocation was required for that development.
0.7 ETs continued to be allocated in respect of a development application by one Ives after the application was withdrawn.
11.5 ETs were double counted in respect of a development at Shirley Street, Byron Bay.
9.75 ETs were double counted in respect of a development application by Aquarius Backpackers.

These errors accounted for 30.28 ETs. In addition, Dansar contended that 39.25 further ETs of the total spare capacity of 92.75 ETs were available for allocation but were not recognised by Council officers to be available because Council officers used the wrong conversion rate in converting the figure of 371 EPs to ETs (see [14] above). This contention was not the subject of detailed submissions on appeal because the impact of the errors listed above exceeded by a considerable margin the capacity of between 11.6 and 12.4 ETs required for the Dansar development. I add that there appears to be an error of one ET in the schedule Dansar supplied to this Court, probably making the effect of the alleged conversion rate error 38.25 ETs rather than 39.25 ETs but the difference is of no consequence.

THE JUDGMENT AT FIRST INSTANCE

The primary judge summarised Dansar's case as follows:

"2 Amongst the many planning issues raised by the development application was a question as to the extent of Byron Shire's spare sewage treatment capacity. The present claim rests critically on the Council's consideration of that issue. In broad terms the developer, Dansar Pty Ltd, asserts that the Council negligently underestimated the degree of spare sewage treatment capacity in Byron Shire and overestimated the extent to which such capacity was already at least notionally allocated to existing properties or other approved developments, resulting in its denying the existence of spare capacity sufficient to meet the requirements of Dansar's proposal."

Her Honour made the following further observations concerning Dansar's claim:

"12 ... Dansar's claim focuses acutely on that aspect of the process, being based on the assertion that the Council owed a duty of care to developers, in effect, to get those calculations right. Implicitly, the claim assumes the existence of a private right to have any (correctly calculated) spare capacity allocated for new development.

...

45 ... The essence of the claim is that, having adopted a system for the allocation of the spare capacity identified, the Council failed to implement that system (or made errors in doing so). Implicitly, the premise of the claim is that, regardless of any assumption of responsibility or specific reliance, the adoption of a system informs the existence and content of a duty of care."

The primary judge's reasons for concluding that the Council did not owe Dansar the duty alleged are indicated by the following extracts from her Honour's judgment:

"82 The disconformity between the duty of care asserted by Dansar and the Council's statutory functions is manifest. Many of the functions exercised by the Council within the complex statutory regime considered above focus critically on considerations of public health and environmental impact. The existence of a private right to recover relational interest damages in respect of a failure to allocate sewage treatment capacity to an individual property developer is plainly inimical to the unimpeded exercise of such functions. That consideration alone militates powerfully against imputing a duty of care of the content asserted by Dansar.

...

84 ... [T]he fact that the public interest is a relevant and potentially determinative consideration in any development application is inconsistent with the imposition of a duty on the Council to take care in the allocation of putative units of sewage treatment capacity, less still to do so in a timely fashion.

...

87 In my view, that submission [that the Council had a high degree of control in calculating available sewage treatment capacity] entails two misconceptions. First, it looks with telescopic focus to the financial interests of developers as if that were the only interest required to be served by the exercise of the Council's several functions. Secondly, it treats sewage treatment capacity as if it were a fixed, measurable resource which the Council had an obligation to quantify correctly and to allocate exhaustively. That overlooks the complexity of the sewage issue, for the reasons explained by Mr Warner considered above, and the importance of the Council's separate function as the sewage management authority. The present case is quite different from the position of a certifying authority where the matter required to be certified is known to the Council and not known to the person for whose protection the certificate is issued. The control exercised by the Council, and the degree of vulnerability of the person seeking the certificate or approval, in cases of the kind discussed by Hodgson JA in Makawe derives from a more focussed task.

...

90 The want of reasonable care asserted in the present case is the Council's alleged failure, due to mistakes of calculation or wrong information, to identify enough spare sewage treatment capacity to satisfy itself as to the existence of 'prior adequate arrangements' for the purpose of clause 45 of the Byron Local Environmental Plan. In short, it is a complaint that the Council negligently failed to allow a greater burden on the sewerage system. To say that Dansar was unable to protect itself from the consequences of such negligence in a way that should cast the consequences of the loss on the Council assumes not only that there existed an objective, 'correct' quantity of spare sewage treatment capacity but that all such capacity was required to be allocated for development: see plaintiff's written submissions, paragraphs 29, 53. Each of those premises highlights the disconformity between the duty of care asserted by Dansar and the unimpeded performance of the Council's statutory functions. For the reasons given in the evidence of Mr Warner, the Council's calculation of spare capacity or available ET, whilst helpful for planning purposes, was ultimately no more than theoretical. Further, the Council was under no legal duty to allocate all spare capacity calculated. To adopt such an approach would plainly be in conflict with the proper exercise of its other functions.

91 The vulnerability asserted by Dansar is a want of protection of an economic interest which, as the foregoing analysis of the statutory context reveals, stands in competition with many other interests of varied vulnerability and importance. Dansar ought reasonably to have expected and planned its business on that basis. Mr Vaughan emphasised in his evidence that, until he saw the draft statement of issues in the proceedings in the Land and Environment Court, there were 'no concerns...at all about sewerage': T78.49. However, in the absence of any specific reliance by Dansar on any positive representation by the Council, I do not think it can be concluded that Dansar was vulnerable in the sense explained by the High Court in Woolcock. The recognition of a duty of care to protect an individual against such vulnerability would skew the careful balance of competing interests sought to be achieved by the statutory regime of regulation and management."

RELEVANT CASE AUTHORITY

As indicated by Mason J in Sutherland Shire Council v Heyman [1985] HCA 41; 157 CLR 424 at 457-8, there is "no reason why a public authority should not be subject to a common law duty of care in appropriate circumstances in relation to performing, or failing to perform, its functions, except in so far as its policy-making and, perhaps, its discretionary decisions are concerned". Thus, as a general proposition, "when statutory powers are conferred they must be exercised with reasonable care", with the consequence that the repositories of the powers will be liable for damages for negligence if loss results (Stuart v Kirkland-Veenstra [2009] HCA 15; 237 CLR 215 at [117] per Gummow, Hayne and Heydon JJ).

Likewise, in Caledonian Collieries Ltd v Speirs [1957] HCA 14; 97 CLR 202 at 220, Dixon CJ and McTiernan, Kitto and Taylor JJ referred to the "well-settled principle" that:

"when statutory powers are conferred they must be exercised with reasonable care, so that if those who exercise them could by reasonable precaution have prevented an injury which has been occasioned, and was likely to be occasioned by their exercise, damages for negligence may be recovered".

In Precision Products (NSW) Pty Ltd v Hawkesbury City Council [2008] NSWCA 278; 74 NSWLR 102 at [75], Allsop P (with whom Beazley and McColl JJA agreed) described this passage from Caledonian as "part of the fabric of the common law in the task of the ascertainment of the existence and scope of the duty of care" (see also MM Constructions (Aust) Pty Ltd v Port Stephens Council (No 7) [2012] NSWCA 417; 191 LGERA 292 at [90]). His Honour however emphasised that the passage did not justify the imposition of a duty of care in every case falling within its description. Rather, against the background of the general principle outlined, whether a duty of care existed in a particular case was to be determined by the circumstances of the case, including the statutory background and framework in which the relevant conduct occurred or allegedly should have occurred.

In Sutherland Shire Council v Heyman, Mason J further observed (at 468) that "a duty of care cannot arise in relation to acts and omissions which reflect the policy-making and discretionary elements involved in the exercise of statutory discretions". His Honour distinguished between policy decisions and operational decisions, indicating in relation to the former that "a public authority is under no duty of care in relation to decisions which involve or are dictated by financial, economic, social or political factors or constraints" (at 469).

In cases such as the present where the plaintiff's alleged loss is purely economic, the courts have been cautious in concluding that a duty of care existed. Many considerations are relevant but central to the issue are those to which McHugh J referred in Perre v Apand Pty Ltd [1999] HCA 36; 198 CLR 180 at [105] of "reasonable foreseeability of loss, indeterminancy of liability, autonomy of the individual, vulnerability to risk and the defendant's knowledge of the risk and its magnitude". A more extensive list of "salient features" was given by Allsop P in Caltex Refineries (Qld) Pty Ltd v Stavar [2009] NSWCA 258; 75 NSWLR 649 at [103]. Of particular relevance in the present context are the following factors to which his Honour referred:

"103 ...

(o) the existence of conflicting duties arising from other principles of law or statute;

(p) consistency with the terms, scope and purpose of any statute relevant to the existence of a duty; and

(q) the desirability of, and in some circumstances, need for conformance and coherence in the structure and fabric of the common law."

The exclusive possession by a statutory authority of information of central importance to the dealings between that statutory authority and another person may well support a conclusion that the statutory authority is under a duty of care to deal carefully with that information (see L Shaddock & Associates Pty Ltd v Parramatta City Council (No 1) [1981] HCA 59; 150 CLR 225 at 243 per Stephen J).

Some authorities dealing with claims against local councils that are of potential relevance to the present case are as follows.

In Avenhouse v Hornsby Shire Council (1998) 44 NSWLR 1, this Court found that after the defendant council had approved a subdivision, it was under a duty of care to take the formal steps necessary to give effect to that approval and to do so with due diligence and within a reasonable time. Sheller JA (with whom Mason P and Priestley JA agreed) concluded that the council's failure to certify the plan of subdivision after it had earlier been approved was not related to any policy matter or budgetary constraint (at 22-3), with the result that a duty of care was not precluded.

In Newcastle City Council v Shortland Management Services [2003] NSWCA 156; 57 NSWLR 173, this Court was concerned with the since-repealed s 114 of the Local Government Act 1993 which required a local council to give notice of an application for approval to erect a building to the owners of adjoining lands. It applied if, in the council's opinion, "the enjoyment of the adjoining land may be detrimentally affected by the proposed building after its erection".

The Court held that the defendant council did not owe a common law duty of care to exercise reasonable care in connection with the formation of an opinion under s 114(1) concerning detrimental affectation. Spigelman CJ (with whom Mason P and Sheller JA agreed) observed that "the scope and subject matter of the matter about which the opinion must be formed is not such as can be judged on a standard of reasonable care, as distinct from Wednesbury unreasonableness" (an administrative law, not common law, concept) and concluded that "the subjective nature of the test and the subject matter about which the relevant opinion is to be formed strongly indicate that no common law duty should be found to exist with respect to the formation of the opinion" (at [80] and [82]).

In Armidale City Council v Alec Finlayson Pty Ltd [1999] FCA 330; 104 LGERA 9, the Full Federal Court was concerned with a claim for damages for common law negligence against a local council for granting development applications and approving plans of subdivision when its officers were aware of significant contamination of the subject land. The Court found that it was clearly open to the primary judge to conclude that the council owed a relevant duty of care, the Court observing that the council decisions complained of did not involve policy considerations.

In Precision Products v Hawkesbury City Council, Precision Products claimed damages for the loss it suffered as a result of the allegedly negligent exercise by the respondent council of its power under s 91 of the Protection of the Environment Operations Act 1997 (NSW) to issue notices requiring the clean-up of suspected pollution. The council was alleged to have been negligent in a variety of respects, including issuing two notices on grounds incapable of supporting their issue and denying Precision Products procedural fairness. The Court rejected the posited duty of care because there was an absence of reliance, of assumption of responsibility and of vulnerability, and because the imposition of the alleged duty would have been incompatible with the council's responsibility under the statute in question. Allsop P observed that "[t]o infuse common law duties and the recovery of damages in such a field as the issuing of notices under s 91 where governmental (EPA supervision) and legal (judicial review) controls already exist would introduce an undesirable incompatibility and lack of coherence to the regime of environmental protection" (at [119]). His Honour noted that the position may well be different in a case, such as the present, concerned with a council's approval of a plan or grant of permission for an act to be done or for a person otherwise to engage in activity (at [120]).

In Makawe Pty Ltd v Randwick City Council [2009] NSWCA 412; 171 LGERA 165, the current owner of a residential apartment building claimed damages from a local council for negligently giving approval to previous owners to construct a building at a time when the council was in possession of a geo-technical report indicating that there was a risk of flooding in the then proposed underground carpark. The claim was treated as one for pure economic loss. Hodgson JA (with whom Campbell JA relevantly agreed) reviewed earlier cases in which local authorities were alleged to owe duties of care to developers and purchasers in relation to the former's approval of development and building applications. His Honour (at [43]) said that he did not disagree with any of those cases and drew the following general propositions from them:

"(1) General statements such as that of Gibbs CJ in Heyman, to the effect that when statutory powers are conferred they must be exercised with reasonable care, do not mean that in all cases, where a local authority exercises statutory powers in respect of the approval of subdivisions and/or building work, it owes a duty of care in respect of those approvals to developers and/or subsequent purchasers of the property.

(2) However, if the approving authority is subject to a statutory requirement not to give consent unless it is satisfied of something, the courts may well find a duty, owed to developers and to purchasers, to exercise reasonable care in considering whether it is so satisfied: Taitapanui, Western Districts.

(3) If the approving authority actually knows something seriously detrimental to the subdivision or the building, and is aware that it is likely that developers and/or purchasers do not know this, the courts may well find a duty owed to developers and purchasers to exercise reasonable care in relation to that detrimental feature: Fregnan, Finlayson, Booth.

(4) If the approving authority makes a positive requirement that something be done which otherwise would not be done, the courts may well find a duty owed to developers and purchasers to exercise reasonable care in making that requirement: Fregnan.

(5) If the approving authority is required to consider or take into account some particular matter which bears on the structural integrity of buildings to be erected, the courts may well find a duty owed to developers and purchasers to exercise reasonable care to avoid risks of property damage arising from this matter: Fregnan, Bamford."

In Western Districts (Western Districts Developments Pty Ltd v Baulkham Hills Shire Council [2009] NSWCA 283; 75 NSWLR 706), to which his Honour referred in his second general proposition, a council approved a plan of subdivision even though a required certificate of compliance had not been obtained from the water supply authority. The council was held liable to later owners of a lot in the subdivision for damages resulting from the council's negligent failure to ensure that this certificate had been issued. This Court held that the council owed the plaintiffs a duty of care to satisfy itself that the requirement for a water supply certificate of compliance was met. Preston CJ of LEC (with whom Giles and Campbell JJA relevantly agreed) found that there was no issue of coherence with administrative law as there had been in Precision Products v Hawkesbury City Council.

Taitapenui (Moorabool Shire Council v Taitapanui [2006] VSCA 30; 14 VR 55), to which Hodgson JA also referred in relation to his second proposition, was a case in which a local council was held liable (on the basis that it was the employer of a building surveyor) for loss suffered by subsequent purchasers of a building for which its surveyor had negligently approved a building permit.

In Makawe, Hodgson JA considered the case before him to be finely balanced but concluded (as did the other members of the Court) that the council did not owe a relevant duty of care. One of a number of matters that his Honour took into account was that the council had not been shown to have actual knowledge of something seriously or potentially detrimental to the owner of the building of which the council would have been aware that the developer did not know ([45]). Campbell JA similarly emphasised the absence of proof that the council had knowledge that others concerned in the construction of the building did not have ([71]). His Honour also emphasised the absence of any relevant communication between the plaintiff (as a subsequent owner) and the council ([69] and [73]).

In MM Constructions, developers sued the respondent council for damages for negligence in its handling of a development application and subsequent modification applications. The developers failed because it was held that there had been no relevant reliance, no assumption of responsibility and no vulnerability, and that the posited duty did not conform to the statutory framework. Important to the latter finding was the existence of a statutory framework for challenge to the council's decisions by way of appeal and the necessity in deciding whether to grant approval for the council to consider "the broad range of interests public and private of the kind set out in the EPA Act, ss 5 and 79C" (at [98]).

THE ISSUES ON APPEAL

Dansar submitted on appeal that the primary judge erroneously characterised the duty it alleged as a duty on the part of the Council to correctly allocate the spare sewerage treatment capacity by forming an opinion about a matter of some complexity involving public health, economic and other considerations.

Dansar submitted that the alleged duty was in fact very different in that it focused only on the mechanical or operational task of implementing the scheme of sewerage allocation which the Council had decided to pursue. The alleged duty was thus said to be to take reasonable care in performing the mechanical or operational tasks of allocating the spare capacity of the West Byron STP which the Council had identified as being available for new developments, and informing itself as to the outcome of that process. Mr Bannon SC, senior counsel for Dansar, submitted that the Council had made "a basic error of maths" and that Dansar was in a highly vulnerable position because there was nothing it could do to investigate the correctness of the Council's calculations (Transcript p 35).

Dansar submitted that if the relevant Council officers had not made basic errors of a mechanical nature, the Council would undoubtedly have concluded that Clause 45 of the LEP (see [10] above) had been satisfied and would have granted development approval in a timely fashion. Dansar emphasised in this connection that the evidence showed that the Council was at all relevant times willing, and intending, to allocate sewerage capacity to Dansar's development if that capacity was available, which the Council would have realised it was if basic calculations had been made carefully.

In response, the Council relied upon the primary judge's approach and submitted in particular that there was a lack of coherence between the alleged duty and relevant statutory provisions.

The Council's opposition to a finding of a breach of duty, in the event of a finding that a relevant duty existed, was of a limited character only. Separately, it relied upon ss 43, 43A and 44 of the Civil Liability Act in defence of Dansar's claim.

As noted earlier, the parties agreed that if the issue of liability was determined in Dansar's favour, the proceedings should be remitted to the Common Law Division for determination of the issues of causation and quantum of damages.

RESOLUTION OF THE APPEAL

DUTY OF CARE

The nature of Dansar's complaints

The essence of the primary judge's reasons for concluding that no relevant duty of care was owed was that such a duty of care would be inconsistent with "the unimpeded performance of the Council's statutory functions" (see Judgment [90] quoted in [44] above). Her Honour's view was that the Council's performance of its statutory functions concerning sewerage involved the resolution of issues of some complexity and required the Council to have regard particularly to considerations of public health and environmental impact (Judgment [82] and [87]). Performance of those functions therefore required the exercise of judgment about questions on which more than one view was available and involved issues of public policy.

The authorities referred to in [45] to [61] above would undoubtedly preclude a finding that the Council owed to private developers such as Dansar a generalised duty to exercise its statutory functions concerning sewerage and developments in a careful fashion. Certainly no duty of care would be owed in respect of the exercise of a judgment of the type referred to in the preceding paragraph. However, there is no reason why a statutory authority such as the Council may not be subject to specific duties of care related to aspects of its functions that do not involve matters of judgment, opinion or public policy (see for example Sutherland Shire Council v Heyman referred to in [45] and [48] above). The decision in Avenhouse (see [52] above) illustrates this proposition. In that case, the Council's decision to approve the subdivision would undoubtedly have involved questions of judgment and policy, with the result that the Council would not have been under a duty of care in the making of it. However the steps following approval of the subdivision were of an "operational" character, to use the word Mason J used in Sutherland Shire Council v Heyman at 469 (see [48] above). There was no reason why the Council should not be subject to a duty of care in taking them, as the Court held it was.

As Dansar submitted, the steps of which it complained in the present case were of this character. The Council officers determined in mid-2000 that the West Byron STP had a capacity of 371 EPs (converted by Council officers to 92.75 ETs) available for allocation and at its meeting on 19 September 2000, and on a number of occasions thereafter, the Council proceeded upon the basis that this was the case and that that capacity should be allocated to developments as applications for approval were received thereafter (see [14] to [19] above). As a result of the mechanical errors identified in [40] to [41] above, Council officers believed by December 2001 that the 92.75 ETs spare capacity had been duly allocated to development applications other than that of Dansar (see [28] and [32] above).

It is clear from the evidence that if the Council and its officers had not laboured under this mistaken belief, sufficient of the 92.75 ETs spare capacity would have been allocated to Dansar's development to fulfil its sewerage requirements, with the consequence that the Council, when exercising its development control functions, would inevitably have been satisfied, in terms of Clause 45(1) of the LEP, "that prior adequate arrangements [had] been made for the provision of sewerage, drainage and water services to the land" on which Dansar's development was proposed to be undertaken (see [10] above).

When, if at all, prior to the actual approval date of 20 June 2005, the Council would have approved Dansar's development application if it had been satisfied in terms of Clause 45(1) of the LEP earlier is not a question for present determination. It is a question of causation to be addressed on remission of the proceedings to the Common Law Division. Unless it is determined favourably to Dansar, Dansar will not obtain a substantial damages award.

What I have said above does not indicate that once the Council and its officers began to use the figure of 92.75 ETs available capacity the Council remained bound, vis á vis Dansar or otherwise, to adhere to that figure and allocate it to development applications. On the contrary, it was at all times open to the Council to take a different judgmental or policy view about the available capacity and to act upon it, but it did not do so. So long as it adhered to the figure of 92.75 ETs, it was in my view, subject to my consideration of other "salient features" relevant to the imposition of a common law duty of care to which I will turn below, subject to a common law duty of care in the operational task of allocating it to developments for which approval was sought.

The relevance of the increased sewage flows

The Council submitted that the increased sewage flows in the Byron Bay area that Mr Warner identified in his memorandum of 15 February 2002 (see [30] above) indicated that the Council was not, and could not be, obliged to allocate the previously ascertained figure of 92.75 ETs because that figure was based on lesser sewage flows occurring at an earlier time. It would of course have been open to the Council, on the basis of Mr Warner's view, to decide not to allocate any remaining part of the 92.75 ETs because of changed circumstances, but the Council did not do this.

In December 2001 the Council's approach to the sewerage requirements of Dansar's development turned on the question of whether any of the previously identified 92.75 ETs spare capacity for the West Byron STP remained unallocated (see [26] and [28]). The position remained the same after Mr Warner's memorandum of 15 February 2002, as demonstrated by Mr Warner's evidence for use at the LEC hearing and the submissions made at that hearing, in March 2002, on behalf of the Council (see [32] and [33] above). The Commissioner's decision similarly turned on that question and the Council memorandum of 27 March 2003 showed that the Council was still utilising the figure of 92.75 ETs in 2003 ([34] and [35] above). Furthermore, by notice dated 9 December 2011, the Council admitted that from 20 September 2000 until 2005 it used the calculation of the West Byron STP's spare capacity of about 92 ETs to allocate ETs to each of the 36 development applications lodged with the Council between 20 September 2000 and 1 March 2001 (this being the period during which Dansar's application was lodged). The notice refers to 92.4 ETs but this is not, at least for present purposes, materially different from 92.75 ETs (see [14] above).

The primary judge said that "[f]or the reasons given in the evidence of Mr Warner, the Council's calculation of spare capacity or available ET, whilst helpful for planning purposes, was ultimately no more than theoretical" and that "the Council was under no legal duty to allocate all spare capacity calculated" (Judgment [90] quoted in [44] above).

Her Honour's reference to Mr Warner's evidence was apparently to his evidence in these proceedings that Dansar's reliance on 92.75 ETs "spare capacity" identified by the Council's engineers confused "a prediction of capacity with the actual measured or assessed capacity of the plant to process greater loads of sewage" (Judgment [15]). This evidence demonstrated why the Council, consistently with the discharge of its statutory functions, could not have been under any obligation to adhere to an estimate made at one time as conditions and considerations later changed. However, for the reasons already given, this is not a reason to deny the existence of a duty of care in relation to the implementation of an approach that the Council adopted, and continued to apply notwithstanding changed circumstances.

Certainly, as the Council submitted, its performance of its statutory functions required it to have regard to the actual measured or assessed capacities at the relevant time but there is no basis for concluding in the present case that it did not do so. In particular, the Council was conscious of the increased flows identified by Mr Warner but did not change its decision to make 92.75 ETs of capacity available to developers. For the same reason, the Council's reliance on a concession it alleged that Dansar's expert witness, Mr David Bristow, made in his evidence, that in light of the increased sewage flows it would not have been unreasonable for the Council to have refused Dansar's development application, is misplaced.

Clause 45 of the LEP

The Council relied on appeal upon this Court's decision in Codlea Pty Ltd v Byron Shire Council [1999] NSWCA 399; 105 LGERA 370 in which a development application relating to and subject to the Byron LEP was refused because the Council was not satisfied, in terms of Clause 45(1) of the LEP, that "prior adequate arrangements" had been made for the provision of sewerage services for the proposed development. The Court held that an appeal against the refusal of the development application entitled the Court to substitute its own satisfaction under Clause 45 for the Council's lack of satisfaction, but the Court could not make an arrangement concerning sewerage where none had been made by the Council. The Court accepted that the "arrangements" referred to in Clause 45 extended at least to "willingness on the part of the relevant authorities to co-operate in a consensual way" (at [40]).

In reliance on Codlea, the Council submitted that the duty of care asserted by Dansar "would be incoherent with the purely factual nature of the Byron LEP Clause 45 pre-condition, and the consequently unexaminable fact of the absence of any such sewerage arrangements" (written submissions [16.8]). However in the present case the requirements of Clause 45(1) would have been satisfied if the Council had taken reasonable care in performance of the operational steps involved in the allocation of the identified spare capacity. The consensual element of Clause 45(1) to which Codlea adverted was satisfied by the Council's undoubted willingness to allocate sewerage capacity to Dansar's development if sufficient of the 92.75 ETs spare capacity identified were available. The element of satisfaction would have been present if the Council had carefully allocated the identified spare capacity because it would have been apparent to it that there was not only, as the Council had given Dansar to understand (see [16] and [18] above), a willingness on its part to provide capacity in response to Dansar's application but also an ability to do so. Contrary to the Council's submission, the alleged duty was thus not inconsistent with the existence of a discretion in the Council to make or not make arrangements of the type referred to in Clause 45(1).

Whether inconsistency with the statutory framework

In argument on the appeal the Council emphasised two issues of coherence between the posited duty of care and the relevant statutory framework. First, it contended that a common law duty of care could not "relevantly attach to a non-statutory decision not to enter into a sewerage arrangement" (Transcript p 41). However Dansar did not contend that the posited duty would do this. That duty was not one "to enter into a sewerage arrangement" but a duty of the Council to take reasonable care in its allocation of identified spare sewerage capacity. On Dansar's case, compliance with this duty would have led to the Council appreciating that Clause 45 of the LEP had been satisfied, because there was both a willingness and an ability of the Council to make an allocation to Dansar of the sewerage capacity required for its development.

Secondly, the Council asserted that there was a lack of such coherence by reason of s 179 of the LGA (see [9] above). However, this section applies only where a council has been "unduly influenced by vexatious or unmeritorious submissions made by members of the public" or has acted "vexatiously" (s 179(1)). Neither of these circumstances is present here and I do not consider any implication can be drawn from the section, or otherwise, that it was intended to operate exhaustively, with the consequence that a common law duty of care directed at other circumstances would be inconsistent with it.

In summary, I find that the statutory framework was not inconsistent with the posited duty of care. The conduct to which Dansar's claim was directed did not concern the Council's consideration of environmental, public hygiene or other policy factors (compare Precision Products and MM Constructions referred to in [56] and [61] above). Nor did it involve questions of judgment or opinion (compare Newcastle City Council v Shortland at [53] to [54] above). Rather, the conduct involved mechanical steps more analogous to those with which Avenhouse, Armidale City Council and Western Districts (see [52], [55] and [58] above) were concerned. The general propositions formulated by Hodgson JA in Makawe (see [57] above) also provide some support for my conclusion, particularly the second proposition. Unlike the position in Makawe, there was here direct communication and a relationship between the plaintiff and the Council and the Council was in possession of information concerning the allocation of spare capacity for the West Byron STP of which it knew or should have known Dansar would be unaware (see also Shaddock referred to in [50] above).

Other relevant factors

I turn now to consider other factors of relevance to the existence or non-existence of a duty of care in the present case.

In my view the element of reliance was present here. In September 2000 the Council concluded that a limited amount of spare capacity of the West Byron STP (371 EPs which it converted to 92.75 ETs) was available for allocation (see [15] above). Dansar was given reason to believe (see [16] above) that its development would receive an appropriate allocation and lodged its application accordingly. It was totally reliant for its allocation on the Council's careful dispensation of the spare capacity. The Council was the sole repository of the information and calculations necessary to determine whether any of the 92.75 ETs were available for Dansar and therefore had a high degree of control over what occurred. Moreover, unlike the position in Precision Products (see [56] above), the conduct occurred in the context of the Council exercising a power (of approval of a development application) for the benefit of Dansar. In embarking on its exercise it assumed (subject to issues arising out of the statutory framework) a responsibility to Dansar. Dansar was vulnerable, at least because it had no effective right of appeal, it not having the knowledge of the Council's steps in allocating the 92.75 ETs spare capacity that would have enabled it to know that it had cause for complaint. Moreover, the decision in Codlea (see [79] above) would have constituted a significant, although perhaps not insurmountable (see [80] above), impediment to an appeal being mounted.

Other factors favouring the imposition of a relevant duty of care are that Dansar and the Council were, by reason of Dansar's lodgment of its development application and the Council's responsibility to deal with it, in a close "one-to-one" relationship and the likelihood of Dansar suffering harm from the absence of or delay in approval of its development application would have been readily foreseeable to a reasonable council in the position of the respondent.

My view is that in these circumstances the Council owed Dansar the duty of care Dansar alleged. The statements of general principle referred to in [45] to [50] above support the imposition of that duty, as does a consideration of the particular circumstances of the case. For the reasons I have given, the statutory context in which the Council acted did not require a different conclusion.

BREACH OF DUTY

In argument on the appeal, Mr P W Taylor SC, who appeared for the Council, confined his arguments concerning breach to the statutory defences that I address below and to one that the increased sewage flows identified in early 2002 (see [30] above) constituted changed circumstances rendering it reasonable for the Council to depart from its earlier intention to allocate 92.75 ETs of the spare capacity of the West Byron STP, with the result that there was no breach of duty in not allocating any of that capacity to Dansar. The Council relied particularly on the evidence of Mr Warner and the alleged concession by Mr Bristow (see [78] above) in this respect. However, this change of circumstances does not answer Dansar's case because, as I have pointed out, the Council decided nevertheless to continue to allocate the previously identified spare capacity of 92.75 ETs. On Dansar's case, it was negligent in doing this.

In light of the rejection of this latter argument of the Council, it follows from the manner in which the Council's case was put that, unless any of the statutory defences assist the Council, the conclusion that it committed a breach of duty must follow (see the appeal transcript at pp 70-71).

The earliest date upon which Dansar ultimately came to allege that a breach occurred was 29 January 2002, the date when the Council rescinded that part of its earlier resolution which recognised Dansar's entitlement to an allocation. I accept that a breach occurred on this date as, at least by then, the Council and its staff should have realised that a careful allocation of the identified spare capacity of 92.75 ETs would have led to an allocation being available to Dansar to meet its development's requirements.

THE STATUTORY DEFENCES

Dansar submitted that the Council ought not to be permitted to rely on appeal upon its pleaded statutory defences under s 43, 43A and 44 of the Civil Liability Act (see [11] to [12] above). Dansar pointed to the absence of a Notice of Contention and of written submissions lodged prior to the appeal hearing addressing the defences. To this I would add the circumstance that the primary judge did not deal with the defences. Nevertheless, I would permit the Council to rely upon them as any prejudice to Dansar was overcome by Dansar being afforded the opportunity to lodge, after the appeal hearing, a written submission concerning the defences.

Section 43 Civil Liability Act

This section applies only to proceedings "based on a breach of a statutory duty" (s 43(1) - see [11] above). The section is thus inapplicable in the present case because Dansar's claim is not so based but it is based upon a breach of a common law duty of care.

Section 43A Civil Liability Act

On appeal, the Council did in substance do no more in relation to its s 43A defence than adopt its first instance written submissions relating to that issue. Those submissions contended, but only in a limited fashion, that the Council's conduct was not unreasonable in the sense referred to in s 43A(3) (see [11] above). The Council relied in this respect only on the argument addressed above arising out of Codlea (see [80] above) and on its argument, also addressed above, concerning the increased West Byron STP sewage plant flows in early 2002 (see [74] above). For the reasons that I have given above (see [77] and [80]), neither of these arguments answer Dansar's claim. In my view, neither addressed the factual situation in the present case where the Council had a continuing intention to allocate 92.75 ETs from the West Byron STP capacity but failed to take carefully the mechanical steps involved in doing so. Bearing in mind the standard of negligence referred to in s 43A(3) (as to which see Precision Products at [175]-[177]), it would in my view have been necessary for the Council to contend, and establish, that the careless mistakes it made in relation to the allocations (see [40] above) were not capable of being described as ones which no council acting reasonably could have made. As it did not do either, its defence under s 43A fails.

In light of the limited submissions provided to this Court on the statutory defences, it is not necessary or appropriate to deal with any other hurdles the Council may have faced in relying on this or the other defences.

Section 44 Civil Liability Act

This section is concerned with the failure of an authority such as the Council "to exercise or to consider exercising any function of the authority to prohibit or regulate an activity ..." (s 44(1)). The present is not such a case. It is concerned with an aspect of the Council's functions in approving developments. There is no allegation that the Council failed to prohibit or regulate any activity of Dansar, or of any other person.

CAUSATION

The parties agreed that unless the Court considered that remittal would plainly be futile (and Dansar's claim would therefore fail because the Council's breach of duty caused it no loss), the issue of causation should be remitted to the Common Law Division for determination. On appeal, the issue of causation was not addressed by the parties in detail but there is in my view nothing in the material put before the Court to indicate that Dansar's case on causation is hopeless. As a result, the issue should be remitted.

ORDERS

As Dansar is entitled to succeed on the only issue with which the primary judge dealt, namely duty of care, the appeal should allowed.

I propose the following orders:

(1) Appeal allowed.

(2) Set aside the order made by the primary judge on 30 January 2013 and any order made thereafter concerning the costs of the proceedings at first instance.

(3) Remit the proceedings to the Common Law Division for it:

(a) To determine whether the appellant suffered any loss, and if so how much, as a result of the respondent's breach of duty as found by this Court; and

(b) To enter judgment and make consequential orders, including as to the costs of the proceedings at first instance.

(4) Order the respondent to pay the appellant's costs of the appeal.

MEAGHER JA: The respondent Council has responsibility for the care and management of the water, sewerage and drainage works for the Byron Shire and supplies those services to the community living in that area. The issue in this appeal is whether, when considering an application for the allocation of sewerage capacity for its proposed development, the Council owed a duty of care to the appellant property developer. It will be necessary later in these reasons to consider more closely the content of that asserted duty which is said to be concerned only with the carrying out of the 'mechanical' task involved in allocating capacity previously determined to be available. The appellant alleges that but for the Council's breach of that duty its application for the construction of a residential complex would have been approved three years earlier than occurred and that it suffered financial loss as a result. That loss includes profits which the appellant alleges it would have obtained had the development been approved earlier. The appellant does not allege that it relied upon the accuracy of any advice or information provided by the Council.

Introduction

One of the sewage treatment plants which the Council operates and manages is the West Byron sewage treatment plant (West Byron STP). That plant was first commissioned in 1990. In early 2000 works upgrading that plant were completed. Those works increased its average design flow capacity to 2,000kL/day and its peak dry weather flow capacity to 2,500kL/day.

Those design capacities may also be expressed in EPs or ETs. An EP, an abbreviation for equivalent person, is a standard measure of sewerage load (hydraulic as well as biological) based on the estimated daily contribution to the load of a typical person in a residential setting (which takes account of all zonings in that setting including residential, commercial and industrial). ET or equivalent tenement describes the potential daily hydraulic load generated by a standard household connected to the sewerage system. These measures are used when establishing the design capacity of a sewage treatment plant and estimating the potential sewage contribution of developments within the sewage catchment area. The assumption ordinarily made as to usage by an equivalent person is 240L/day. The assumption as to the ratio of ETs to EPs can vary according to factors such as population density and is contestable in the sense that for a given catchment area there is likely to be a range of values which might be justified as reasonable, at one end conservative and at the other, less so.

In June 2000 the Council carried out an assessment to determine the existing and committed loads at its sewerage facilities, including the West Byron STP. To do so it measured the hydraulic load based on actual flows into that plant. The current load was 1,588.8kL/day. It then estimated the "committed" load which consisted of undeveloped lots deemed to have an entitlement to sewerage services (because they were in a reticulated area where owners were already paying sewerage rates) and land or properties the subject of development applications which had been approved. It did so adopting the assumptions 1 EP = 240L/day and 1 ET = 4 EPs. It then subtracted the current and committed load from the plant's design capacity. The "spare" capacity was assessed to be 371 EPs, which was then expressed as 92.75 ETs.

In September 2000 the Council, in its capacity as sewerage authority, resolved not to enter into any arrangement or agreement for the provision of further sewerage services to any proposed development which would increase the load on the West Byron STP beyond its present capacity for non-peak loads of 8,333 EPs or 2,000kL/day. The effect of that resolution, based on its earlier assessment, was that the Council should not enter into any new arrangements for the provision of sewerage services that would result in the estimated spare capacity of 371 EPs being exceeded. The imposition of any additional load was described as seriously jeopardising the plant's ability to meet its "EPA licence criteria and to comply with Council's statutory obligations for pollution control".

The appellant's case before this Court was that the Council was negligent in carrying out the "operational and mechanical" task of implementing its decision to allocate that spare capacity. By narrowing the content of the asserted duty of care in this way the appellant sought to meet an argument that the suggested duty of care would be incompatible with the Council's statutory and other obligations. It submitted that this narrower duty arose "once the Council's functions had been exercised in resolving to allocate some [capacity] to new development applications". In its written submissions the appellant described the subject matter of the duty of care for which it contended in the following terms:

In the way the appellant's case is formulated, whether the Council owed it a duty of care and whether it suffered any economic loss depend on the Council's having adhered to its earlier acknowledgement of available capacity and decision, albeit uncommunicated at the time, as to how that capacity might be allocated. If in January 2002 the Council had reassessed the question of capacity by reference to the more recent data relied upon by Mr Warner, it could have concluded that there was no available uncommitted capacity. Alternatively, it may have decided to reserve any capacity which was otherwise available for a particular use or development such as a hospital or nursing home. In either event, the appellant's application for an allocation of capacity would have been refused in circumstances to which the suggested duty of care would not have applied. That this is so exposes a fundamental difficulty for the appellant's case. The primary judge points to that difficulty in her reasons at [45] where it is observed that the earlier adoption by the Council of a methodology for the allocation of capacity "informs the existence and content" of the duty of care.

In Vairy v Wyong Shire Council at [60] Gummow J warned against the danger of focussing on the alleged breach when addressing the existence and content of any duty of care. That is because that is a question of law to be determined prospectively. One risk of doing so is that the duty will, as in this case, be framed retrospectively by too specific reference to what happened: per Hayne J in CAL No 14 Pty Ltd v Motor Accidents Insurance Board [2009] HCA 47; 239 CLR 390 at [68]. A related risk is that the question as to the existence of the duty will not be addressed prospectively.

Where it is said that a public authority owes a duty of care, it is necessary to identify the function or power, the performance or exercise of which is the subject matter of the alleged duty. Having done so, as the joint judgment in Sullivan v Moody makes clear at [60], it is then necessary to address whether the existence of that duty would give rise to inconsistent obligations in the performance of that function or conflicting claims upon the exercise of the power. These questions are part of the prospective inquiry as to the existence and content of the duty. They are not answered, as the appellant's argument would have it, by looking to the way in which the public authority acted on the particular occasion in question and asking whether its doing so in fact required it to give consideration to conflicting claims, or engaged statutory obligations inconsistent with that duty.

The function in relation to which it is said the Council owed a duty of care was that of deciding whether to increase the permanent load on the treatment works by the amount of capacity required for the appellant's development. That question arose in the context of its determining whether to approve that development. The Council undertook that function between December 2001 and February 2002. There were two particular matters to which it had to give attention. The first was whether, as sewerage authority, it should allocate capacity and consent in principle to the development being connected to the public sewer. The second was whether, as consent authority, it was satisfied that there was an arrangement within cl 45(1) of the Byron LEP.

Those questions had to be addressed consecutively and the answer to the second was dictated by the answer to the first. In addressing the first the Council was required to give paramount consideration to the safety and continued operation of the treatment facilities, maintaining public health and protecting the environment. That obligation and the interests to which the Council was to have regard are incompatible with the existence of a private law duty to take reasonable care to avoid economic loss to a developer resulting from refusal of or delay in its development approval.

Furthermore, that incompatibility is not avoided by restricting the duty to what is described as the "mechanical" task of allocation. When the Council was considering the appellant's application in the period from December 2001, it remained subject to these statutory obligations. In deciding, by its rescission resolution of 29 January 2002, to adhere in relation to the appellant's development to the methodology it had previously adopted, the matters to which the Council was able to have regard included any recent data as to loadings on the treatment plant as well as the assumptions and calculations underlying the earlier report of its officers of 18 December 2001. The decision to adhere to the earlier methodology was not a "mechanical" one. It involved a judgment as to whether the previous methodology and the assumptions and calculations which informed it should be applied to that development.

For these reasons the primary judge was correct to conclude that there was a disconformity between the alleged duty of care and the Council's statutory functions and obligations and that the existence of such a duty would be "inimical to the unimpeded exercise" of those functions. That incompatibility would ordinarily be a sufficient reason for denying the existence of the duty: Sullivan v Moody at [60].

There are other features of the relationship between the parties that must be considered. They are the foreseeability of harm, indeterminacy, reliance and assumption of responsibility, and the vulnerability of the appellant. The primary judge concluded that there was "no relevant reliance, no assumption of responsibility and no vulnerability in the relevant sense": [85], [91], [92]. I agree with each of those conclusions.

Foreseeability of harm. As Allsop P observed in MM Constructions (Aust) Pty Ltd v Port Stephens Council at [93], delay in or rejection of a development approval can readily be seen to have economic consequences for a developer. To that extent, in the present case it was foreseeable that a developer might incur some financial disadvantage if its development application was delayed or refused.

However, the risk of harm to which the suggested duty is directed is not all or any delay in the approval of the development application, or all or any such delay due to a refusal to allocate or delay in allocating sewage treatment capacity. It is only the risk of economic harm resulting from delay or refusal of a development application due to negligence in the mechanical or operational task of allocating capacity.

In that event, the applicant would only suffer financial loss as a result of any delay or refusal if there were spare capacity that would have been allocated earlier, but for the relevant negligence. Whether there was capacity available for allocation was a matter for the judgment of the Council as sewerage authority and not something in respect of which there could be only one "correct" answer. As the primary judge observed at [87] treatment capacity was not a "fixed, measureable resource which the Council had an obligation to quantify correctly and to allocate exhaustively".

Assuming that but for the relevant negligence the Council would have concluded that there was capacity available, whether the appellant would suffer financial loss as the result of any delay or refusal of its application would then depend on a range of factors, some of which would not in the ordinary course be known to the Council. Those factors include the developer's intentions with respect to the development; any alternative opportunities available to the developer with respect to the use or sale of the undeveloped property; the costs of proceeding with the development, including financing and construction costs; and the revenues received or anticipated before, during and on completion of the development.

Although in a general sense it was foreseeable that the appellant might suffer detriment if its development was delayed or refused due to carelessness in allocating capacity, it was not foreseeable that the appellant would inevitably do so: cf Caltex Oil at 577, and Perre v Apand at [131], [216].

Indeterminacy. The present case is not one in which the liability of the Council is indeterminate in any relevant sense: see Caltex Oil at 568 (Stephen J); Perre v Apand at [106] - [108] (McHugh J) and Woolcock v CDG at [21] (Gleeson CJ, Gummow, Hayne and Heydon JJ). The class of potential claimants is those who lodged development applications in the period between August 2000 and February 2001. The general nature of their claims and the measure of the damages that might be claimed can realistically be determined.

Reliance and assumption of responsibility. Liability claims for negligent misstatement or advice ordinarily depend upon the presence of known reliance and an assumption of responsibility. The speaker must realise, or the circumstances must be such that it ought to have realised, that the recipient intends to rely upon the information or advice in connection with some matter of business or serious consequence and the circumstances must be such that it is reasonable for the recipient to seek or accept, and to rely upon, the information or advice: Tepko Pty Ltd v Water Board at [47] (Gleeson CJ, Gummow and Hayne JJ), citing Mutual Life & Citizens' Assurance Co Ltd v Evatt [1968] HCA 74; 122 CLR 556 at 571 (Barwick CJ).

The presence of reliance is also an indication of 'vulnerability' as that notion is understood: Perre v Apand at [10] (Gleeson CJ); Woolcock v CDG at [24] (Gleeson CJ, Gummow, Hayne and Heydon JJ). The vulnerability arises because of the recipient's known reliance on the defendant as the source of advice or information.

In preparing and lodging its development application the appellant had the assistance of expert town planning advice. It also had access to officers and staff of the Council, of whom it could make inquiries, and to the public deliberations and resolutions of the Council and reports presented at its public meetings. The fact that the appellant and its advisors exercised that access is apparent from the terms of its original development application, the evidence of Mr Vaughan as to his dealings with the Council and the correspondence between the Council and the appellant's town planners.

At the time it lodged its development application the appellant had an expectation that there would be capacity available for its development. However, it did not have any assurance from the Council to that effect or any assurance as to the way in which any available capacity would be allocated. The appellant at the same time must be taken to have appreciated that in determining that there was or was not available capacity, the Council was bound to consider whether increasing the permanent load on the plant, by granting capacity, would compromise its operation.

At no time did the appellant seek any assurance from the Council that it would act carefully or competently in implementing, or making, a decision about available capacity. Instead, assurances were sought that capacity was or would be available to its development. The terms of those requests show that the appellant was not proceeding on the basis that it had any entitlement to receive capacity or to have capacity allocated in a particular way. In that context, the more specific subject of whether the Council staff might make calculation errors in implementing any decision about how capacity was to be allocated was not a matter to which the appellant expressly addressed attention.

The appellant may have had an expectation that the Council would undertake the exercise of allocation equitably and competently but, as Allsop P also observed in MM Constructions v Port Stephens Council at [94], that was "no more than a reasonable expectation of members of the public". That expectation would include an appreciation that from time to time errors are made in the conduct of the activities of a public or private service provider which affect the supply of its services. As Gillard J noted in Johnson Tiles Pty Ltd v Esso Australia PtyLtd [2003] VSC 27; Aust Torts Reports 81-692 at [1017], whilst it may be taken for granted that service providers will be efficient and timely, experience shows that nothing is guaranteed. At no time was the appellant relying on any express or implied assurance from the Council that it would allocate available capacity in a particular way and exercise reasonable care in doing so.

Vulnerability. The notion of vulnerability includes circumstances in which a plaintiff is unable to protect itself from the consequences of a defendant's want of reasonable care. That may be because it has exercised that ability by placing reliance on the defendant for information or advice. As the above analysis shows, that is not so in this case. It may also be because the plaintiff's enjoyment of a right, interest or expectation is controlled in some relevant sense by the defendant: Pyrenees Shire Council v Day at [168] (Gummow J); Perre v Apand at [38] (Gaudron J), [129] (McHugh J).

The economic loss claimed by the appellant is the amount necessary to put it in the position it would have been in had it received a timely allocation of capacity and development approval. That loss includes expenses that it says would not have been incurred if development approval had not been delayed and benefits in the form of profits that it says would have been realised. In Hill v Van Erp [1997] HCA 9; 188 CLR 159 the economic loss suffered by the intended beneficiary was the value of an expected testamentary benefit the receipt of which depended totally on the exercise of care in relation to work (specifically the preparation of a will and the securing of its proper execution) which the solicitor had agreed to perform.

The appellant had no right or entitlement to have any further load committed to the sewerage system. Nor did it have an expectation to that effect, the enjoyment of which necessarily depended on the exercise of care by the Council in relation to a task that it was obliged to perform. The Council was able at any time in the discharge of its responsibility as sewerage authority to determine that there should be no further increase in the permanent load to the treatment works or decide that any such increase should be allocated to specific developments or in a particular way. In these respects the appellant's position is to be contrasted with that of the plaintiffs in Hill v Van Erp, Caltex Oil and Perre v Apand. In Caltex Oil the detriment suffered was the loss of the enjoyment of Caltex's right to use property (the pipeline) which was vital to the ongoing conduct of its business: at 576-577 (Stephen J). In Hill v Van Erp the intended beneficiaries' interests were "totally and unavoidably dependent upon the proper performance of a function within the sole province of the solicitor": at 186 (Dawson J). In Perre v Apand, the plaintiffs were denied access to the "principal and lucrative market" in which they were selling and entitled to sell their potatoes: at [195] (Gummow J). Here, by way of contrast, the appellant's continued enjoyment of any right or interest or expectation was not controlled by the Council. There was no such right or interest, the enjoyment of which depended on the exercise of care by the Council or the existence of which depended on the exercise of care by the Council in the performance of a function that it was obliged to undertake.

The appellant appreciated at the outset that there was a risk that its development may be delayed or not proceed or proceed in a different form. There were several reasons why that might have occurred. An aspect only of one of those reasons is sought to be made the subject of a duty of care. The appellant was well positioned with the assistance of its expert advisors, and after making inquiries of the Council, to assess before it lodged its application the risk that there would be insufficient sewerage capacity available. It was also in a position to defer the incurring of significant expenses in relation to the development until such time as it had made an arrangement with the Council for the allocation of capacity. In the absence of any such arrangement the appellant may have proceeded in part on an expectation that the Council and its officers would act competently and responsibly in relation to the care and management of the sewerage facilities. At the same time it was foreseeable as a possibility that its development might be refused or delayed in circumstances where reasonable care was not taken. However, that fact and the fact that it might suffer detriment as a result were not sufficient to make it vulnerable in the relevant sense: Woolcock at [23].

Conclusion

Consideration of these features of the relationship between the appellant and the Council, and the statutory context which informs it, points clearly to the conclusion that the Council was not subject to the suggested duty of care. The appellant's claim is for economic loss in circumstances where there was no reliance or assumption of responsibility or relevant vulnerability so as to justify the imposition of that duty. Furthermore to do so would involve subjecting the Council to conflicting claims and obligations in relation to its care and management of the sewerage works.

This conclusion makes it unnecessary to consider any question of breach; and, in any event, it is not useful to do so in circumstances where the Council does not seriously contest that if it owed the narrow duty of care contended for that duty may have been breached.

The appeal should be dismissed and the appellant ordered to pay the respondent's costs.

LEEMING JA: I agree with the reasons and conclusions of Meagher JA. This Court being divided, I should explain why I respectfully disagree with the judgment of Macfarlan JA, which I have also had the advantage of reading in draft. As I see the position, much of the difficulty in this appeal is linguistic, and may be avoided by carefully distinguishing the various duties owed, and the different functions performed, by the Council.

This is not a case where Dansar alleged that it relied on any representation by the Council. That was expressly disavowed. The duty for which Dansar contended arose upon the submission, in February 2001, of its development application, and continued so long as the Council chose to consider that application. Dansar's development application, consistently with cl 45 of the Byron Local Environmental Plan 1998 and the temporary availability of "Equivalent Tenements" or "ETs", stated that:

"Recent studies have indicated that the West Byron [Sewage] Treatment Plant has spare capacity sufficient to accommodate the wastewater load from the proposed development. Based on Council's normal requirements, each two-bedroom development will generate a sewer load of 0.7 ET. The whole development therefore will generate 11.6 ET (18 x 0.7 minus 1 ET 'credit'). [Sewage] from the site will be directed into Council's existing sewerage system, taking advantage of the existing capacity available."

The application referred in terms to cl 45 and said:

"The site can be adequately served with water, telephone and electrical services. In relation to sewer, we understand that limited capacity exists at the West Byron plant, and we would seek to connect to the existing system to exploit that capacity."

No party disputed that the Council's power was confined by cl 45(1) of the Byron LEP 1998. The Council had no power to grant consent "unless it is satisfied that prior adequate arrangements have been made for the provision of sewerage ... ". That is to say, the Council's state of satisfaction was a condition precedent to the exercise of power under s 80 of the Environmental Planning and Assessment Act 1979 (NSW) (EP&A Act). In that sense it may be said to be jurisdictional: Barrick Australia Ltd v Williams [2009] NSWCA 275; 74 NSWLR 733 at [26]. The state of satisfaction must be regularly formed, and could be challenged on judicial review, in accordance with what Latham CJ said in R v Connell; ex parte Hetton Bellbird Collieries Ltd [1944] HCA 42; 69 CLR 407 at 432. Indeed, "any person" (for example, the neighbours some of whom objected to the Dansar's development application) could bring Class 4 proceedings to challenge the consent: see McGovern v Ku-ring-gai Council [2008] NSWCA 209; 72 NSWLR 504. It is trite that any body exercising public power must first satisfy itself that the preconditions have been satisfied. In the case of courts, it has been said to be "the very first duty of any Court" and "the first duty of every judicial officer": Hazeldell Ltd v Commonwealth [1924] HCA 36; 34 CLR 442 at 446; Federated Engine-Drivers' and Firemen's Association of Australasia v Broken Hill Proprietary Co Ltd [1911] HCA 31; 12 CLR 398; see also Eberstaller v Poulos [2014] NSWCA 211 at [1] and [14].

But although it is conventional and appropriate to describe Council's obligation to satisfy itself of the preconditions to any exercise of power as a "duty", such duty is distinct from the private law duty urged by Dansar in this appeal. For one thing, Council never exercised the power to grant or refuse consent under the EP&A Act (ultimately, the Land and Environment Court dismissed an appeal from Council's deemed refusal) and so there was no occasion for it to reach the state of satisfaction required by cl 45(1). For another, the private law duty for which Dansar contends is one whose breach sounds in damages, rather than vitiating an exercise of public power. For a third, as narrowly formulated, it was a duty to take reasonable care in allocating spare sewerage capacity previously determined to be available. That duty was, correctly, regarded by Dansar as distinct from the determination of available sewerage capacity, which Dansar accepted was not subject to the alleged duty of care.

Dansar alleged that the Council was required to give "proper consideration" to its development application, including proper consideration as to whether "prior adequate arrangements had been made". That submission conflates the obligation upon the Council to satisfy itself of a precondition to the exercise of its power to grant consent, in its capacity as consent authority, with the Council's functions as sewerage authority. It is the latter which matters for present purposes.

In determining whether the duty for which Dansar contends exists, it is necessary to ask a question which may seem to be quite artificial. Was the Council exercising its functions under the EP&A Act (responding to a particular application for consent by a landowner), or was the Council exercising its functions as a sewerage authority, implementing spare sewerage capacity in accordance with a resolution reflecting an evaluation of competing and diverse interests (such as the existing demand, the environmental impacts and compliance with the Council's licence)? The artificiality arises because in the present case, the same Council performed both functions, but that will not always be so. The force of Codlea Pty Ltd v Byron Shire Council [1999] NSWCA 399; 105 LGERA 370 is that the function of entering into an "adequate arrangement" is outside the functions exercised in a Class 1 appeal by the Land and Environment Court pursuant to s 39(2) and therefore distinct from the Council's functions under the EP&A Act.

I accept that Dansar's application for development consent necessarily amounted to its seeking an arrangement for the provision of sewerage for 11.6 ETs (for without the Council being satisfied of the existence of such an arrangement, it had no power to grant consent). However, where (as Dansar accepted) the Council had no duty in formulating, from time to time, the policies it would put in place for allocating the limited sewerage capacity, which necessarily were approximate, contestable and liable to change at any time and without notice, it is difficult to see how there could be a duty to take reasonable care in the implementation of those policies so as to avoid pure economic loss.

The foregoing is wholly consistent with the reasons of Meagher JA. The analysis required to determine the existence of a duty to take reasonable care is, necessarily, more wide-ranging than the matters to which I have referred, and I gratefully agree with the whole of his Honour's reasons. I would add that I regard this appeal as an unusual case; ordinarily, it might be expected that such cases would involve reliance by the plaintiff upon a representation made by Council about how its policies were being implemented.
