Agreement in English law

The most important feature of a contract is that one party makes an offer for a bargain that another accepts. This can be called a 'concurrence of wills' or a 'meeting of the minds' of two or more parties. There must be evidence that the parties had each from an objective perspective engaged in conduct manifesting their assent, and a contract will be formed when the parties have met such a requirement.^[2] An objective perspective means that it is only necessary that somebody gives the impression of offering or accepting contractual terms in the eyes of a reasonable person, not that they actually did want to contract.^[3]

Where a product in large quantities is advertised for in a newspaper or on a poster, it is generally regarded as an offer, however if the person who is to buy the advertised product is of importance, i.e. his personality etc., when buying e.g. land, it is merely an invitation to treat. In Carbolic Smoke Ball, the major difference was that a reward was included in the advertisement which is a general exception to the rule and is then treated as an offer. Whether something is classified as an offer or an invitation to treat depends on the type of agreement being made and the nature of the sale. In retail situations an item being present is normally considered an invitation to treat; this was established for items on display in shop windows in Fisher v Bell [1961] 1 QB 394 and for items on shelves in Pharmaceutical Society of Great Britain v Boots Cash Chemists (Southern) Ltd [1953] 1 QB 401.

Retail agreements can also be considered invitations to treat if there is simply not enough information in the initial statement for it to constitute an offer.^[4] In Partridge v Crittenden [1968] 1 WLR 1204 the defendant had placed an advertisement indicating that he had certain birds for sale, giving a price but no information about quantities. He was arrested under the Protection of Birds Act 1954 for 'offering such birds for sale'; it was ruled that since the advertisement did not specify the number of birds he had it could not constitute an offer; if it did he could have been legally bound to provide more birds than he possessed.^[4] The same principle was applied for catalogues in Grainger v Gough [1896] AC 325, when it was ruled that posting catalogues of items for sale to people did not constitute an offer since there was insufficient detail.^[4]

During that period he withdrew the offer. The court held that "the offeror was entitled to revoke his offer at any time prior to acceptance because no option agreement existed",^[5] which would have obliged Grant to keep the offer open.

An offer can be rejected by the offeree(s). An offer which is rejected is thereby extinguished: see Hyde v Wrench (1840) 3 Bea 334.

When an offer is stated to be open for a specific length of time, the offer automatically terminates when it exceeds the time limit. See:

• Ramsgate Victoria Hotel v Montefiore (1866) LR 1 11 Ex 109
• Manchester Diocesan Council for Education v Commercial Investments Ltd

• In Bradbury et al. v Morgan et al. (1862),^[6] the court ruled that a death does not in general operate to revoke a contract, although in exceptional cases it will do so.^[7]

A writes to B offering to sell certain property at a stated price. B writes to A offering to buy the same property at the same price. The letters cross in the post. Is there (a) an offer and acceptance, (b) a contract?

In this case, it is assumed that "where offers cross there was no binding contract", because B's acceptance was not communicated to A. Therefore, there was no contract what so ever.

• Tinn v Hoffman (1873) 29 LT 271: "A rejection terminates an offer, so that it can no longer be accepted." The authority cited in Bonner Properties Ltd v McGurran Construction Ltd, a Northern Ireland case of 2008, is Tinn v Hoffman and Company (1873):

  In that case Mr Tinn was negotiating with the defendants for the purchase of some 800 tons of iron. The exchange of correspondence between them dealt with quantity, time and price. The majority of the Court of Exchequer held that there was no binding contract as the plaintiff's purported letter of acceptance of 28 November did not constitute the same as it was too late for the defendant's offer to sell contained in the letter of 24 November (which had requested "your reply by return of post"). On appeal to the Court of Exchequer Chamber the majority of that court (Blackburn, Keating, Brett, Grove and Archibald JJ, with Quain and Honeyman JJ dissenting) affirmed this judgment of the majority below.^[8]

Revocation can be made by the offeror only before acceptance is made. Also the revocation must be communicated to the offeree(s).Unless and until the revocation is communicated, it is ineffective. See:

• Byrne v Van Tienhoven (1880) 5 CPD 344.
• Hudson ‘Retraction of Letters of Acceptance’ (1966) 82 Law Quarterly Review 169

If the terms of the contract are uncertain or incomplete, the parties cannot have reached an agreement in the eyes of the law.^[9] An agreement to agree does not constitute a contract, and an inability to agree on key issues, which may include such things as price or safety, may cause the entire contract to fail. However, a court will attempt to give effect to commercial contracts where possible, by construing a reasonable construction of the contract (Hillas and Co Ltd v Arcos Ltd^[10]).

Courts may also look to external standards, which are either mentioned explicitly in the contract^[11] or implied by common practice in a certain field.^[12] In addition, the court may also imply a term; if price is excluded, the court may imply a reasonable price, with the exception of land, and second-hand goods, which are unique.

If there are uncertain or incomplete clauses in the contract, and all options in resolving its true meaning have failed, it may be possible to sever and void just those affected clauses if the contract includes a severability clause. The test of whether a clause is severable is an objective test—whether a reasonable person would see the contract standing even without the clauses.
