Submissions and reasoning
14 Mr Moore provided detailed written and oral submissions in support of his argument that the contract pursuant to which the appellants acquired the property was made on 13 September 1985. He submitted that facts accepted by the AAT showed that by this date the appellants had made an oral offer to purchase identifiable property at a specified price and that the vendor, Mrs Ransom, had accepted this offer. Mr Moore submitted that the AAT's mistake had been to confuse the task of identifying the time of the making of the contract with the quite different task of identifying the time when the contract became enforceable. Moreover, the finding of the AAT that the parties remained in negotiations until the date of exchange of the written contract on 31 October 1985 was said to be "totally unreasonable and perverse". Concerning the statement by the vendor's solicitor in the letter dated 13 September 1985 that there was to be no liability until exchange, Mr Moore submitted that the evidence showed it was made without authority. The vendor subsequently countermanded the position and instructed her solicitor to date the contract 13 September 1985.
15 Mr Erskine of counsel, for the respondent, pointed out that in addition to the factors identified by the appellants as being necessary to a valid contract, it is also necessary that the parties intend to enter into a binding contract. He pointed to a clear finding by the AAT that the parties did not intend to be legally bound until exchange of contracts. It is worth noting the AAT's comments:
"… this Tribunal has undertaken the task of examining the totality of what has been placed before it with respect to whether the accepted evidence discloses any contract recognised by the common law and the time of the making of any such contract. The Tribunal finds that there was one contract and one only which had the attributes prescribed by the common law and that was the Agreement for Sale of Land referred to throughout these reasons as "the written contract". Until the execution and exchange of the written contract there was not a contract and what had taken place prior to that point in time clearly fell into the 3rd class delineated in Masters and Another v Cameron (1954) 91 CLR 353. As to the time of the making of the above contract the Tribunal finds that it was 31 October 1985. This was the first time that there was a meeting of the minds, a consensus reached incorporating an intention to form legal relations. This was the time that the common law would acknowledge that a contract had come into existence between the parties."
16 The AAT's finding of fact that 31 October 1985 was the first time that the parties had reached a consensus with the intention to form legal relations was made after a careful examination of the evidence. In my opinion, this finding was open to the AAT on the evidence and it is not for the Court to interfere with that finding.
17 In support of his contention that a binding agreement was reached on the earlier date (13 September), Mr Moore submitted that this was a commercial agreement and that it is rare for commercial agreements not to be intended to have legal consequences. He referred the Court to relevant passages in Carter and Harland Contract Law in Australia 2nd ed. 1991 at [401] and the cases referred to there. However, this argument does not take account of the strong convention concerning the sale of land in New South Wales which has been the subject of judicial comment on numerous occasions.
18 In Allen v Carbone (1975) 132 CLR 528 at 533, the High Court commented that the "usual method of selling real estate in New South Wales is by means of the signing and exchange of contracts in the form approved by the Real Estate Institute of New South Wales". It relied on this practice to support an inference that the parties did not intend an informal agreement for the sale of the property to be binding. In GR Securities Pty Ltd v Baulkham Hills Private Hospital Pty Ltd (1986) 40 NSWLR 631, McHugh JA in the NSW Court of Appeal referred to the method of exchange at 634 and stated that "even though the parties agree in writing that real estate is sold for a specified price, the presumption is that no binding contract exists until 'contracts' are exchanged". This presumption or expectation has been accepted in many other cases; see for example Sindel v Georgiou (1984) 154 CLR 661 at 665-666, Elgas Ltd. v A. J. Young Industries Pty. Ltd. (1987) NSW ConvR ¶55-329 at 57,016 per McHugh JA and Kirton v Nethery (1996) 7 BPR 14,954. In Lezabar Pty. Ltd. v Hogan (1989) NSW ConvR ¶55-468 ("Lezabar")at 58,387-58,388, Gleeson CJ noted that in Allen v Carbone (above) the High Court had referred to this issue as "the first consideration" and commented:
"One reason why this consideration is important is that the form of contract ordinarily used contains important provisions for the protection of both parties, and a court would not lightly attribute to knowledgeable parties an intention to forgo such protection."
19 In this case, as in Lezabar, the agreed facts show that the parties were aware of this method of selling land and contemplated that contracts of the usual kind would be exchanged in due course. They both put the matter in the hands of their solicitors. On the very day on which the parties agreed on the sale, the vendor's solicitor forwarded a contract to the purchaser's solicitor and specifically noted that "no legal liability shall attach to either party until such time as exchange has been effected". There followed a period of negotiation involving such things as the amount of the deposit, the inclusions and the identification by survey of the property. All of these factors tend to confirm that the parties here adopted the usual method of sale and purchase of land in New South Wales and that they did not intend to be bound by the oral agreement between them.
20 Neither my comments here nor the authorities cited above should be taken as denying that it is possible for a contract for the sale of land in New South Wales to be effected other than by exchange of contracts. Ultimately, the intention of the parties as to whether they enter into binding obligations is decisive; Masters v Cameron (1954) 91 CLR 349 at 360-2. In reaching the point from which they intend to be bound, they may agree that one of the terms of the contract is that certain obligations under it are to be retrospective to a specified date. However, the date of the formation of the contract is a matter of law and the parties cannot, by backdating the written document, rewrite history with the effect that a binding contract existed from the specified date.
21 No special form of words is necessary to ensure that an agreement is binding or not binding. However, the practice in New South Wales of proceeding by exchange of contracts is so entrenched that a party contending for an intention to proceed other than in accordance with the established procedure will need clear evidence to support the contention. As Bryson J commented in Dowdle v Inverell Shire Council (1999) 195 ANZ ConvR 429 at 431:
In New South Wales courts approach questions relating to supposed informal contracts for the sale of land with a disposition towards finding that the parties intended to use the ordinary mechanism of an exchange of contract to achieve a binding contract."
22 In the decision appealed from, Finn J pointed out (at [15]) that the crucial aspect, from the appellants' point of view, was that the Tribunal did not believe Mr McDonald.
"It was not because of error of law that Mr McDonald lost his application to the Tribunal. It was because he was not believed. And once his evidence was disregarded, that which remained pointed inexorably to the conclusion at which the Tribunal arrived."
23 I respectfully agree. The appeal must be dismissed with costs.
