"Where parties who have been in negotiation reach agreement upon terms of a contractual nature and also agree that the matter of their negotiation shall be dealt with by a formal contract, the case may belong to any of three cases. It may be one in which the parties have reached finality in arranging all the terms of their bargain and intend to be immediately bound to the performance of those terms, but at the same time propose to have the terms restated in a form which will be fuller or more precise but not different in effect. Or, secondly, it may be a case in which the parties have completely agreed upon all the terms of their bargain and intend no departure from or addition to that which their agreed terms express or imply, but nevertheless have made performance of one or more of the terms conditional upon the execution of a formal document. Or, thirdly, the case may be one in which the intention of the parties is not to make a concluded bargain at all, unless and until they execute a formal contract.
In each of the first two cases there is a binding contract: in the first case a contract binding the parties at once to perform the agreed terms whether the contemplated formal document comes into existence or not, and to join (if they have so agreed) in settling and executing the formal document; and in the second case a contract binding the parties to join in bringing the formal contract into existence and then to carry it into execution. Of these two cases the first is the more common. Throughout the decisions on this branch of the law the proposition is insisted upon which Lord Blackburn expressed in Rossiter v Miller (1878) 3 App Cas 1124 when he said that the mere fact that the parties have expressly stipulated that there shall afterwards be a formal agreement prepared, embodying the terms, which shall be signed by the parties does not, by itself, show that they continue merely in negotiation. His Lordship proceeded: " . . . as soon as the fact is established of the final mutual assent of the parties so that those who draw up the formal agreement have not the power to vary the terms already settled, I think the contract is completed" (1878) 3 App Cas, at p1151: see also Sinclair, Scott & Co Ltd v Naughton [1929] HCA 34; (1929) 43 CLR 310, at p 317. A case of the second class came before this Court in Niesmann v Collingridge [1921] HCA 19; (1921) 29 CLR 177 where all the essential terms of a contract had been agreed upon, and the only reference to the execution of a further document was in the term as to price, which stipulated that payment should be made "on the signing of the contract". Rich and Starke JJ observed (1921) 29 CLR, at pp 184, 185 that this did not make the signing of a contract a condition of agreement, but made it a condition of the obligation to pay, and carried a necessary implication that each party would sign a contract in accordance with the terms of agreement. Their Honours, agreeing with Knox CJ, held that there was no difficulty in decreeing specific performance of the agreement, "and so compelling the performance of a stipulation of the agreement necessary to its carrying out and due completion" (1921) 29 CLR, at p 185: see also O'Brien v Dawson [1942] HCA 8; (1942) 66 CLR 18, at p 31.
Cases of the third class are fundamentally different. They are cases in which the terms of agreement are not intended to have, and therefore do not have, any binding effect of their own: Governor & c of the Poor of Kingston-upon-Hull v Petch [1854] EngR 995; (1854) 10 Exch 610 (156 ER 583). The parties may have so provided either because they have dealt only with major matters and contemplate that others will or may be regulated by provisions to be introduced into the formal document, as in Summergreene v Parker [1950] HCA 13; (1950) 80 CLR 304 or simply because they wish to reserve to themselves a right to withdraw at any time until the formal document is signed. These possibilities were both referred to in Rossiter v Miller (1878) 3 App Cas 1124. Lord O'Hagan said: "Undoubtedly, if any prospective contract, involving the possibility of new terms, or the modification of those already discussed, remains to be adopted, matters must be taken to be still in a train of negotiation, and a dissatisfied party may refuse to proceed. But when an agreement embracing all the particulars essential for finality and completeness, even though it may be desired to reduce it to shape by a solicitor, is such that those particulars must remain unchanged, it is not, in my mind, less coercive because of the technical formality which remains to be made" (1878) 3 App Cas, at p 1149. And Lord Blackburn said:
'Parties often do enter into a negotiation meaning that, when they have (or think they have) come to one mind, the result shall be put into formal shape, and then (if on seeing the result in that shape they find they are agreed) signed and made binding; but that each party is to reserve to himself the right to retire from the contract, if, on looking at the formal contract, he finds that though it may represent what he said, it does not represent what he meant to say. Whenever, on the true construction of the evidence, this appears to be the intention, I think that the parties ought not to be held bound till they have executed the formal agreement (1878) 3 App Cas, at p 1152.'
So, as Parker J said in Von Hatzfeldt-Wildenburg v Alexander (1912) 1 Ch 284, at p 289 in such a case there is no enforceable contract, either because the condition is unfulfilled or because the law does not recognize a contract to enter into a contract.
The question depends upon the intention disclosed by the language the parties have employed, and no special form of words is essential to be used in order that there shall be no contract binding upon the parties before the execution of their agreement in its ultimate shape: Farmer v Honan [1919] HCA 13; (1919) 26 CLR 183. Nor is any formula, such as "subject to contract", so intractable as always and necessarily to produce that result: cf Filby v Hounsell (1896) 2 Ch 737. But the natural sense of such words was shown by the language of Lord Westbury when he said in Chinnock v Marchioness of Ely [1865] EngR 335; (1865) 4 De GJ & S 638 (46 ER 1066): "if to a proposal or offer an assent be given subject to a provision as to a contract, then the stipulation as to the contract is a term of the assent, and there is no agreement independent of that stipulation" [1865] EngR 335; (1865) 4 De GJ & S 638, at p 646 (46 ER, at p 1069). Again, Sir George Jessel MR said in Crossley v Maycock (1874) LR 18 Eq 180:
'If the agreement is made subject to certain conditions then specified or to be specified by the party making it, or by his solicitor, then, until those conditions are accepted, there is no final agreement such as the Court will enforce (1874) LR 18 Eq, at pp 181, 182.'
This being the natural meaning of "subject to contract", "subject to the preparation of a formal contract", and expressions of similar import, it has been recognized throughout the cases on the topic that such words prima facie create an overriding condition, so that what has been agreed upon must be regarded as the intended basis for a future contract and not as constituting a contract. Indeed, Lord Greene MR remarked during the argument in Eccles v Bryant and Pollock (1948) Ch 93, at p 94 that when the expression "subject to contract" was used he had never known a case in which it had been suggested, much less held, that this did not import that there was nothing binding till the exchange of parts of the formal contract was made. The effect of the early cases on the subject was stated by Sir George Jessel MR in Winn v Bull (1877) 7 Ch D 29 when he said in a passage which has become well-known:
It comes, therefore, to this, that where you have a proposal or agreement made in writing expressed to be subject to a formal contract being prepared, it means what it says; it is subject to and is dependent upon a formal contract being prepared. When it is not expressly stated to be subject to a formal contract it becomes a question of construction, whether the parties intended that the terms agreed on should merely be put into form, or whether they should be subject to a new agreement the terms of which are not expressed in detail (1877) 7 Ch D, at p 32.
The subsequent cases on the point have been numerous, and it will suffice to refer to two only in addition to those already cited. A case very like the present is Santa Fe Land Co Ltd v Forestal Land etc Ltd (1910) 26 TLR 534 in which an offer was made "subject to a formal contract to be approved by your solicitors and ourselves on acceptance of the offer, when any minor details can be settled". The acceptance of this offer was held by Neville J not to constitute a concluded contract. The learned judge, following Winn v Bull (1877) 7 Ch D 29 said:
Now it is important not only in cases of the sale of land, but in all cases where letters pass with regard to the sale of any property which is being negotiated, that the parties should be able to protect themselves by some suitable words from being bound by the negotiation they are conducting. In the present case I think the words in question do impose the condition that if the offer is accepted a more formal contract is to be prepared by the solicitors which is to embody all the details (1910) 26 TLR, at pp 534-535.
The other case is Spottiswoode Ballantyne & Co Ltd v Doreen Appliances Ltd (1942) 2 KB 32. The Court of Appeal there had to consider an agreement for the letting of premises, expressed to be "subject to the terms of a formal agreement to be prepared by their (the owners') solicitors". The court construed this phrase as meaning that the formal agreement had to be not only prepared by the solicitors but executed by the parties. Lord Greene concluded that the language used was equivalent to the common and more concise phrase "subject to contract", and added that "it is well settled that that phrase makes it clear that the intention of the parties is that neither of them is to be contractually bound until a contract is signed in the usual way" (1942) 2 KB, at p 35. Goddard LJ repeated the observation of Bankes LJ in Keppel v Wheeler (1927) 1 KB 577: "I pause here to state plainly what is now well established, that where a person accepts an offer subject to contract, it means that the matter remains in negotiation until a formal contract is settled and the formal contracts are exchanged" (1927) 1 KB, at p 584."
