10 The facts are not in dispute and may be stated quite briefly. The Defendant acquired the Land in about 1983. It was then known as Lot 164 D.P. 755923, Portion 614 Parish of Conjola.
11 In about 1990 the Defendant formed the intention to subdivide the Land for sale and consulted a registered land surveyor, Mr Beasley, who drew up a proposed plan of subdivision. On 7 December 1990, Shoalhaven Council granted consent to the proposed subdivision. Nothing significant seems to have happened until 29 March 2001 when a plan of subdivision of the land was registered creating Lots 4 and 6 in Deposited Plan 1025204. The Defendant proposed to re-subdivide the Land for sale and in early 2003 he instructed Mr Beasley to act as Project Manager.
12 The Defendant is a businessman, but he himself has no experience in land subdivision. His evidence made it clear that he left virtually all of the management of the subdivision project to Mr Beasley, and became involved only in a minor way in August and September 2003.
13 On 7 March 2003 Mr Beasley, on behalf of the Defendant, lodged an application with Integral Energy for provision of an electricity network for the proposed subdivision. The application, which had been prepared by Mr Beasley himself, stipulated 30 June 2003 as the required date for the supply of electricity to the subdivision. The supply involved two stages: first, the design of the services and next the construction of the services on the Land. Mr Beasley applied to Integral Energy for it to carry out both stages.
14 On 18 March 2003 Mr Beasley advised the Defendant's solicitor, who was then in the process of preparing contracts for sale of lots in the proposed subdivision, that he expected that completion of the registration process would occur within six months. He continued:
"… however a longer period, if obtainable, should be sought, say nine months to protect our mutual client against possible delays."
15 Both Mr Beasley and the Plaintiffs' expert on subdivision procedure, Mr Watkinson, said that to achieve final registration of the proposed plan of subdivision within nine months from the date of the first contract entered into by the Plaintiffs was feasible.
16 On 25 March 2003, the Defendant exchanged contracts for sale of Lot 4 in the proposed subdivision to Mr and Mrs Kierzkowski. On 17 April, the Defendant exchanged contracts for sale with Mr and Mrs Pinches in respect of Lot 4. On 23 April 2003, the Defendant exchanged contracts for sale with Mr and Mrs Tucker in respect of Lot 2.
17 At the time that he lodged the application dated 7 March 2003 with Integral Energy, Mr Beasley was aware that the electricity supply industry had been de-regulated so that neither Integral Energy nor any other supplier had a monopoly of the supply of the electrical services required to be provided prior to registration of the subdivision. In other words, there was a competitive market for the supply of the services which Integral Energy was being approached to supply.
18 As will have been seen from the letter from the Defendant's solicitor to the Plaintiffs' solicitors of 27 October 2003, the only basis upon which the Defendant stated that registration within the nine month period was impossible was the inability to procure electricity supply services within the contractually stipulated time. The sole issue in the case has really come down to this: whether the Defendant, by himself and through his agent Mr Beasley, has done everything reasonable to procure the supply of electricity services for the subdivision to enable the subdivision to be registered within nine months from the date of contract.
19 The evidence is that, after lodgement of the application for supply of electricity services with Integral Energy on 7 March 2003, there was no further correspondence between Mr Beasley or the Defendant and Integral Energy until 14 August 2003.
20 However, during that time Mr Beasley had a number of telephone conversations with a Mr Austin at Integral Energy, in which Mr Beasley inquired about the progress of the design work which Integral Energy was supposed to be doing for the subdivision. He says the first such telephone conversation occurred about four weeks after he lodged the application for services, that is, about early April. In that conversation Mr Beasley says he asked Mr Austin: "Where are the projects up to?" He asked Mr Austin not only about the Defendant's subdivision projects but about a number of other projects in which Mr Beasley was engaged. Mr Austin told Mr Beasley that, in relation to the Defendant's project, he had had a site inspection and was trying to find a suitable route for supply of the services.
21 Mr Beasley says that his next inquiry to Mr Austin was about four weeks later, in about early May. In that conversation Mr Beasley says that he asked Mr Austin, "Where is the design?", referring to the electricity design for the Defendant's subdivision. Mr Austin responded that the site was difficult and he was having trouble finding a route for supply.
22 Mr Beasley says that about three or four weeks later, which would be about early June or late May, he had another conversation with Mr Austin when he asked in relation to the Defendant's subdivision, "Where are you up to?" Mr Austin told him that Integral Energy had not progressed much further.
23 Mr Beasley says that about two weeks later he had another conversation with Mr Austin, in which he again asked Mr Austin, "Where are you up to?" Mr Austin responded that Integral Energy had not progressed any further. Mr Beasley said something to the effect that he needed a design fairly soon. This conversation would probably have occurred about late June.
24 Mr Austin says that about two weeks afterwards, probably mid-July, he again spoke to Mr Austin about the progress of work on the design for the Defendant's subdivision. He says Mr Austin told him that he had the project on his pile of things to do but had not yet got to it. Mr Beasley says that it probably would have been about two weeks later, that is, around early August, that he had another conversation with Mr Austin in which he sought an update regarding progress of the design. Mr Austin told him that Integral Energy had not got to it yet. Mr Beasley told him that the matter was getting urgent.
25 It was apparently only in September that Mr Beasley had a conversation with Mr Austin in which Mr Beasley said that he was extremely disappointed with the failure of Integral Energy to perform the design services, not only for the subdivision of the Defendant, but also for other subdivision projects on which Mr Beasley was advising.
26 On 17 September 2003 Mr Beasley sent by facsimile to Integral Energy a letter dated 15 September 2003. In that letter Mr Beasley sought clarification as to which existing projects Integral Energy would continue to undertake for Mr Beasley's various clients. Among those clients, numbering some eight, was the Defendant. In that letter Mr Beasley concludes:
"We trust you will continue to complete these projects otherwise substantial delays with resulting cost implications will occur for our clients as it is not possible to engage other level 3 service providers at present."
27 On 29 September 2003 Integral Energy responded to that facsimile confirming that it would complete the electrical designs for six projects, amongst the eight specified by Mr Beasley in his facsimile of 17 September. Integral Energy concluded by saying that it would not be undertaking any further design work on the Defendant's subdivision.
28 Having received that letter, the Defendant came to the conclusion that he would, in effect, have to start again with another electricity supplier to procure a design for the subdivision and that it was impossible for that design work to be done and the construction of the consequent electrical works to be carried out in sufficient time to enable compliance with the nine months' deadline contained in clause 28.2 of the contract. The Defendant, in consultation with his solicitors, came to the conclusion that he ought therefore to rescind the contracts with the Plaintiffs pursuant to clause 28.3.
29 On 13 October 2003 the Defendant sent a facsimile to Mr Beasley seeking confirmation that:
"… Integral Energy, at the time we entered the contracts (with the Plaintiffs) , was the sole utility able to supply the service and copies of letters, facsimiles and list of diary dates from the first instance you attempted to get pricing from Integral."
30 Mr Beasley responded by facsimile on 14 October 2003:
"Integral Energy were not the only persons available to design and construct the electricity extension to the subdivision. This work is classed as contestable works in which Integral Energy were competing in an open market."
And continued:
"We had always continued to use Integral Energy as we have found them to be reliable and competitive and had no knowledge that they were contemplating leaving the contestable marketplace until September."
31 This evidence confirms the evidence which Mr Beasley gave in cross examination that, at all material times and certainly by the time he submitted an application to Integral Energy on 7 March 2003, he was aware that Integral Energy was but one of a number of possible competitors in the market for the supply of electrical services to the subdivision.
