OVERVIEW
15The factual background is not substantially in issue because the events and circumstances are identified in the documents in evidence and communications before me and the main issues turn on the characterisation of the conduct in the circumstances.
16On 29 September 2000 the defendants by their planning agent, Forbes Rigby Pty Ltd (Forbes), lodged an application for development consent for the subdivision referred to in the contract. The application was accompanied by a Statement of Environmental Effects prepared by Forbes. This stated that the land is irregularly shaped and dominated by two narrow ridgelines converging to the west which have moderate to steep side slopes which are well vegetated. The northern dwelling on the site is accessed by an all-weather right of way extending from Araluen Avenue and postal services are also delivered from that avenue. The southernmost dwelling, erected sometime after 1984, is accessed by a private access way which connects with the Mount Kembla Ring Track which connects to Cordeaux Road about 800 metres further to the west. The Mount Kembla Ring Track is a public road owned by the Council. Forbes, in their main statement addressed the subject of bushfire risk and rights of way and concluded that the bushfire threat should be no greater by reason of the subdivision.
17Three weeks after lodgement of the development application, on 17 October 2000, the contract was entered into and the payment of $385,000 deposit was made by the plaintiffs. On the same day, the parties executed a mortgage to secure the $385,000 as provided for in special condition 9 of the contract.
18On 28 November 2000, as a consequence of statements by the Council concerning bushfire risks, Forbes engaged Mr Axel von Krusenstierna, a bushfire consultant to comment on the likely bushfire impacts of the proposed subdivision. In his letter of engagement Forbes stated that they agreed with the consultant that the current dwelling on proposed Lot 2 was in a precarious position being sited at the top of a ridge at the head of a long, steep, heavily vegetated gully. They said that in their own previous study prepared for local landowners they had indicated a medium-high bushfire risk for the site but they recorded that in their current Statement of Environmental Effects they did not think that having regard to the proposed access for emergency bushfire purposes the bushfire threat would be any greater by reason of the subdivision.
19On 30 November 2000, Mr von Krusenstierna expressed the view that the southern dwelling was surrounded by bushland with high fuel loads which on the south-eastern side of the dwelling was less than 5 metres from the side of the building. The dense vegetation and steep slopes adjacent to the dwelling placed it in a high hazard area. He said that the Council, in its management plan, had indicated that the bushfire hazard around the southern dwelling was moderate but the consultant considered this was due to a mistaken classification of the surround vegetation as "rainforest". He expressed the view that a reasonable level of fire protection could not be provided for a dwelling on the site of the existing southern dwelling but that the access to the southern part of the land could be improved and the dwelling relocated to a much better position. He canvassed the question of access and fire protection in some detail and considered there should be a two-wheel drive all-weather emergency access route across the proposed Lot 1 to Araluen Avenue for residents on the proposed Lot 2. He considered that the existing dwelling on new Lot 2 should be abandoned in favour of a safer location to the west where it would be able to comply with current standards for fire protection. This indicates that there was concern prior to the grant of development consent about bushfire danger in respect of Lot 2 but the conclusion reached was that the problem could be minimized by relocation of the dwelling on Lot 2.
20Between late 2000 and early 2001 there were further communications between Forbes and the Council in relation to bushfire considerations and access. On 26 February 2001 Forbes notified the Council that they would do what they could to improve the situation via the subdivision through improved access and servicing considerations.
21On 9 April 2001 the Council issued its conditional development consent to the subdivision. It imposed a condition relating to all-weather access for fire-fighting equipment and improvements to services to the dwellings. The consent was for a two-year period which could be extended with Council approval. In addition it was a requirement of the consent that a Construction Certificate had to be obtained before any work commenced on the property. Of particular relevance is condition 6 relating to access which is in these terms:
"ACCESS
6. The developer must construct an all-weather accessway suitable for fire appliances from Araluen Avenue to the southern most dwelling on proposed Lot 2 . The accessway must be a minimum of 5 metres wide and where possible a 2 metre strip each side kept clear of shrubs, bushes and long grass. In this regard tree branches must be lopped where they will obstruct a fire appliance.
The accessway must be capable of supporting a fully loaded fire appliance (28 tonnes or 8 tonnes per axle) . In this regard, the existing concrete strips may be incorporated into the design of the accessway on the provision that written certification is submitted from a suitable qualified Civil and/or Structural Engineer stating that the driveway strips are capable of supporting a fully loaded fire appliance (28 tonnes or 8 tonnes per axle).
Details of the accessway, including plan views, long-sections, cross-sections and the effect of adjoining land must be submitted with the Construction Certification Application for approval by the Certifying Authority. (Emphasis added.)
22After notification of the consent, the Council wrote to the defendants on 17 May 2001, because it appeared that illegal works had been carried out on the property by Mr Foster in breach of the condition which required the prior issue of a Construction Certificate before commencing work.
23On 23 May 2001, Forbes wrote to the Council stating that Mr Foster was happy to assist with resolving the matter by submitting a formal application to the Council for a Construction Certificate as soon as possible. In fact an application for a Construction Certificate was not made until 29 November 2002.
24On 26 September 2001, Forbes wrote to the Council in relation to condition 6 seeking a modification of that condition involving a reduction in width from 9 metres (5 metres wide with 2 metres clearance either side) to 4 metres' clearance in all directions. The letter also pointed out that the proposed track design for the access route could not achieve the maximum grade of 17 per cent as required by the NSW Fire Brigade due to the physical restrictions of the site. They enclosed an application to modify the development consent and a copy of a drawing together with the application fee. A copy of this letter was sent to Mr Foster.
25By 17 October 2001 on expiry of the 12-month period from the date of contract the plan of subdivision had not been registered. However, no decision was made at that time by either party to rescind on the ground that special condition 3 had not been fulfilled. Mr Foster and Forbes thereafter continued to negotiate with the Council to obtain the modification of the consent and registration of the plan. As a consequence of the non-rescission and subsequent conduct, the contract should be taken to have been affirmed and thereafter it continued in force on the basis that it was conditional on registration of the plan within a reasonable time after 17 October 2001.
26On 13 December 2001 the Council issued a notice of determination of the application to modify the consent. The condition of access in the modified consent was varied to read as follows:
"ACCESS
6. The developer must construct an all-weather accessway for emergency evacuation and fire appliance , from Araluen Avenue to the southern most dwelling on proposed Lot 2. The accessway must be a minimum of 4 metres overall clearance in all directions and kept clear of shrubs, bushes and long grass. In this regard tree branches must be lopped where they will obstruct a fire appliance. (Amendment No. 1 - dated 12 December, 2001)
The accessway must be capable of supporting a fully loaded fire appliance (28 tonnes or 8 tonnes per axle) . In this regard, the existing concrete strips may be incorporated into the design of the accessway on the provision that written certification is submitted from a suitable qualified Civil and/or Structural Engineer stating that the driveway strips are capable of supporting a fully loaded fire appliance (28 tonnes or 8 tonnes per axle).
Where accessway grades exceed 1 in 6, appropriate signs are to be erected advising of the excessive grade before ascent and descent points where the excessive grades commence. (Amendment No. 1 - dated 12 December, 2001)
Details of the accessway, including plan views, long-sections, cross-sections and the effect on adjoining land must be submitted with the Construction Certificate Application for approval by the Certifying Authority. (Emphasis added.)
27It should be noted that the relevant variations are indicated in bold on the new condition 6 and also in condition 16(viii) which was modified to read:
"Restriction-as-to-user over proposed Lots 1 and 2 that restricts vehicular access by NSW Fire Brigade and NSW Rural Fire Service fire appliances to those sections of the all-weather accessway equal to or less than 1 in 6. ( Amendment No. 1 - dated 12 December, 2001 )."
28On 8 April 2002 the solicitors for the defendants wrote to the solicitors for the plaintiffs referring to the exchange of contracts stating that at the time of exchange the defendants and their consultants had been led to believe, by officers of the Council, that the proposed subdivision would be a "minor DA" involving predictable but modest expense and capable of approval well within a 12-month period. They stated that the Council in approving the development consent imposed unforeseen conditions some of which were regarded by the consultants as impracticable, impossible or illegal. They noted that the defendants persisted in negotiating with the Council and had obtained a modified consent with new conditions. They referred to the fact that the new conditions required the construction of an access way for fire-fighting purposes without any prior warning or consultation. They noted that Mr Foster estimated that approximately $50,000 additional funding would be required to comply with the Council's current set of conditions which could take up to 12 months to fulfil and that their client, Mr Foster, had not budgeted for such a large additional sum nor did he contemplate paying on-going interest on the advance secured by the mortgage. They stated that they had advised the defendants that they were entitled to rescind the contract and that they proposed to do so in the near future unless the matter could be resolved. They proposed two alternatives. First, that the plaintiffs fund the remaining cost of the development, secondly the possible grant to the plaintiffs of a lease not exceeding five years.
29On 11 April 2002 the solicitors for the plaintiffs recorded that in Forbes' Statement of Environmental Effects in September 2000 they specifically referred to the creation of a right of way to Araluen Avenue for emergency bushfire purposes and that therefore the need for access for such equipment was foreseeable and anticipated. The plaintiffs considered the conditions to be reasonable and necessary in the light of reports by experts highlighting the fire risk to the property.
30There was further correspondence between the parties up to 12 June 2002 and also advice was sought from counsel by the defendants resulting in a facsimile of 12 June 2002 from the solicitors for the defendants stating that the defendants had been advised to proceed with the subdivision. There is also a diary note by Mr Hall dated 14 July 2002 recording a conversation with Mr Foster in which Mr Foster acknowledged he must complete the contract and that he owed Forbes $25,000 and "was going to see them tomorrow to get things moving".
31On 17 September 2002 Forbes wrote to Mr Foster confirming that they had received instructions to undertake the technical investigations for a two-lot subdivision.
32The application for the Construction Certificate was not sent to the Council for a further two-and-a-half months, that is to say not until 29 November 2002. There is no evidence that Mr Foster took any steps to procure the earlier submission of the application for a Construction Certificate, the necessity for which had been stated in the development consent of 9 April 2001.
33On 12 December 2002 the Council wrote to Forbes insisting that the defendants had an obligation to satisfy the requirement that the access way be capable of supporting a fully loaded fire fighting vehicle of 28 tonnes or 8 tonnes per axle. The Council stated that if the defendants wished to delete this condition from the development consent, an amended development application was required and noted that a geotechnical report and sediment control plan as required by the conditions of modified approval had not yet been lodged. The substance of this communication from the Council was notified to Mr Foster shortly thereafter.
34On 19 December 2002 the Council repeated this suggestion in relation to the Construction Certificate and the need to comply with the condition concerning the access.
35No further steps were thereafter taken by Mr Foster or Forbes to amend the access requirements of the modified development consent despite this warning.
36On 9 April 2003 the development consent lapsed as the two-year period had expired and the development had not commenced. A notification to both the original development consent and the modified consent had stated that the duration of the development consent could be extended to three years with the approval of the Council but no attempt was made by Mr Foster or Forbes to extend the two-year period.
37The next event was that Mr Foster obtained a geotechnical assessment from Coffey Geosciences Pty Ltd on 26 June 2003 in relation to slope stability in the vicinity of the proposed access way and as to the measures which could be taken in relation to construction of the access way and erosion control measures.
38On 25 August 2003 the Council notified Forbes that because the development consent had expired, and a 12-month extension to the approval had not been sought, the Construction Certificate would be refused if extenuating circumstances were not demonstrated by Friday, 29 August 2003. The evidence is that this warning was conveyed to Mr Foster shortly after 25 August 2003.
39No action was taken by Mr Foster, as a consequence of this notification, to preserve the development consent as suggested by the Council.
40In fact the development consent was not refused until 3 October 2003 about six weeks after the statement by the Council that an immediate application to extend could be made within five days from 25 August if extenuating circumstances were shown. The formal refusal was expressly based on the fact that the development consent for subdivision had expired.
41On 10 November 2003 Mr Foster wrote to the plaintiffs stating that since the initial development application he had incurred additional expenses of $35,000 in consulting fees alone in attempting to deal with the difficulties imposed by the Council's conditions of consent and related matters so that he was in a position where he was unable to meet his most basic day-to-day living expenses.
42On 29 February 2004 Mr Foster instructed Forbes to cease working on the project and without any further action having been taken over the next six months, on 17 December 2004, the solicitors for the defendants wrote to the plaintiffs' solicitors purporting to rescind the contract and asking for details of amounts owing under the mortgage. The purported rescission was expressed to be based on special condition 4 and clause 19 of the contract both of which are referred to in [5] and [6] above.
43On 3 February 2005 the solicitors for Mr Foster wrote seeking to redeem the mortgage for $385,000. This was rejected.
44On 7 February 2005 the solicitors for the plaintiffs rejected the claim that there had been a rescission and insisted on performance of the contract by the defendants. This was rejected on behalf of the defendants by letter dated 14 February 2005.
45On 20 November 2008 the statement of claim was filed in these proceedings.
46When the matter came on for hearing before me the plaintiffs elected to accept the notice of rescission as a repudiation of the contract and to terminate the contract and sue for damages thereby foregoing the claim for specific performance and pursuing the claim for damages which had been made in the alternative in the statement of claim.
