Introduction
In the law of England and Wales, a legally binding contract is typically formed when there is an offer, acceptance, intention to create legal relations, and consideration. The doctrine of consideration is a fundamental element that distinguishes a simple promise from a legally enforceable agreement. It is often described as the 'price of the promise', requiring that each party to an agreement gives something of value in exchange for what they receive. This principle of reciprocity ensures that contracts are a two-way street, preventing one-sided or gratuitous promises from being legally binding. However, the development of this doctrine through case law has created a set of rules that can sometimes appear technical and rigid. This essay will critically discuss the doctrine of consideration by analysing five key judicial decisions: Currie v Misa (1875), Carlill v Carbolic Smoke Ball Co (1893), Chappell & Co Ltd v Nestle Co Ltd (1960), Tweddle v Atkinson (1861), and Stilk v Myrick (1809). By examining the issues, facts, and judgments of these cases, this discussion will explore how the core principles of consideration have been established and the challenges they can present.
Currie v Misa (1875) LR 10 Ex 153
The Issue
The central issue in Currie v Misa was to define what constitutes valid consideration in the eyes of the law, particularly in the context of a pre-existing debt and a negotiable instrument. The case provided an opportunity for the court to articulate a comprehensive definition of consideration.
Basic Facts
The case involved a transaction between Lizardi & Co., who sold bills of exchange to the defendant, Misa. Payment was to be made at a later date. In the meantime, Lizardi was indebted to their banker, Currie (the claimant). To cover this debt, Lizardi gave Currie a security, which was the debt owed to them by Misa. Before Misa's payment was made, Lizardi encountered financial difficulties. Upon learning this, Misa instructed his bank not to honour the cheque he had issued to pay for the bills. Currie, as the holder of the security, sued Misa for the payment. Misa’s defence was that Currie had not provided any consideration for the promise to pay, as Lizardi's debt to Currie was a past, or pre-existing, debt.
The Judgement
The House of Lords delivered a judgment that has become a cornerstone of contract law. Lush J provided the classic definition of consideration, stating: "A valuable consideration, in the sense of the law, may consist either in some right, interest, profit, or benefit accruing to the one party, or some forbearance, detriment, loss, or responsibility, given, suffered, or undertaken by the other." The court established that consideration involves a benefit to the person making the promise (the promisor) or a detriment to the person to whom the promise is made (the promisee). In this specific case, the court found that a pre-existing debt did not, in itself, form sufficient consideration for a subsequent promise to pay. However, the case ultimately turned on the separate rules concerning negotiable instruments, where consideration is presumed. The lasting impact of the case is its clear and authoritative definition of consideration, which has been cited in countless subsequent cases.
Carlill v Carbolic Smoke Ball Co (1893) 1 QB 256
The Issue
The Court of Appeal in Carlill v Carbolic Smoke Ball Co addressed two main issues. Firstly, whether an advertisement could be considered a serious offer capable of acceptance, creating a binding contract. Secondly, if it was an offer, what consideration was provided by the person accepting it to make the company’s promise to pay enforceable.
Basic Facts
The Carbolic Smoke Ball Company manufactured and sold a product they claimed could prevent influenza. They placed an advertisement in several newspapers which promised a £100 reward to any person who contracted influenza after having used the smoke ball three times daily for two weeks, according to the printed directions. The advertisement further stated that £1,000 was deposited with a bank "shewing our sincerity in the matter." Mrs Louisa Carlill purchased a smoke ball, used it as directed, but still contracted influenza. When she claimed the £100, the company refused to pay, putting forward several defences, including that the advert was mere 'sales puff' and not a serious offer, and that Mrs Carlill had not provided any consideration.
The Judgement
The Court of Appeal rejected all the company's arguments and held that a valid contract had been formed. It found the advertisement was not a mere puff but a unilateral offer to the world, which could be accepted by anyone who performed the specified conditions. On the issue of consideration, the court held that Mrs Carlill had provided valid consideration. This was found in the detriment she suffered by the inconvenience of using the smoke ball as instructed. Furthermore, the company gained a benefit from her actions through the promotion of their product and increased sales. This judgment illustrates that in a unilateral contract, the performance of the requested act by the promisee is sufficient to constitute both acceptance of the offer and the provision of consideration.
Chappell & Co Ltd v Nestle Co Ltd (1960) AC 87
The Issue
The primary legal issue before the House of Lords in Chappell v Nestle was whether items of trivial or non-existent monetary value could be regarded as part of the legal consideration for a promise. This case tested the long-established principle that consideration must be sufficient but need not be adequate.
Basic Facts
As part of a marketing campaign, Nestle offered to sell records of a popular song for one shilling and sixpence (1s 6d) plus three wrappers from their sixpenny chocolate bars. Chappell & Co owned the copyright to the song and were entitled to a royalty based on the 'ordinary retail selling price' under the Copyright Act 1956. Chappell argued that the chocolate wrappers were part of the consideration, and thus the selling price was not just the money but also included the value of the wrappers. Nestle contended that the wrappers were worthless, had no intrinsic value, and were simply a condition to qualify for the offer.
The Judgement
The House of Lords, by a majority, held that the wrappers were part of the consideration. The reasoning was that Nestle had stipulated the wrappers as a requirement, and this provided them with a commercial benefit by increasing the sales of their chocolate bars. Lord Somervell delivered a famous dictum, stating that "A peppercorn does not cease to be good consideration if it is established that the promisee does not like pepper and will throw away the corn." The judgment confirmed the principle that the courts will not inquire into the adequacy of consideration. As long as the promisee provides something of value in the eyes of the law, however small, it will be deemed sufficient consideration. The benefit to Nestle was clear, so the wrappers, despite being thrown away, were part of the price paid for the record.
Tweddle v Atkinson (1861) 1 B&S 393
The Issue
This case concerned the rule of privity of contract and the related principle of consideration. The direct issue was whether a third party, for whose benefit a contract was made, could sue to enforce that contract if they had not personally provided any consideration.
Basic Facts
The claimant, William Tweddle, was engaged to be married. His father and his future father-in-law entered into a written agreement where each promised to pay a sum of money to William. The agreement explicitly stated that William Tweddle "has full power to sue the said parties in any Court of law or equity for the aforesaid sums". The father-in-law died without having paid his promised sum. William Tweddle brought an action against the executor of his father-in-law's estate, Mr Atkinson, to recover the money.
The Judgement
The court found in favour of the defendant, Atkinson. The claim failed because William Tweddle was a "stranger to the consideration." The promises were made between the two fathers, and the consideration for the father-in-law’s promise was the promise made by William’s own father. No consideration had 'moved from' William himself. Wightman J stated that "it is now established that no stranger to the consideration can take advantage of a contract, although made for his benefit." This case firmly established the common law rule that consideration must move from the promisee and reinforced the doctrine of privity, which dictates that only a party to a contract can sue upon it. This principle has since been significantly altered by the Contracts (Rights of Third Parties) Act 1999, but Tweddle v Atkinson remains the foundational case for the common law position.
Stilk v Myrick (1809) 2 Camp 317
The Issue
The key legal issue in Stilk v Myrick was whether the performance of a pre-existing contractual duty could amount to sufficient consideration for a fresh promise made by the other party.
Basic Facts
The claimant, Stilk, was a seaman contracted to crew a ship for a voyage from London to the Baltic and back for a wage of £5 per month. Partway through the voyage, two of the eleven crew members deserted. The captain was unable to find replacements and promised the remaining nine crewmen that he would divide the wages of the two deserters between them if they would work the ship back to London. The crew agreed and completed the voyage. Upon return, the captain refused to pay the extra wages. Stilk sued to recover his share.
The Judgement
Lord Ellenborough held that the claimant was not entitled to the extra money. The reasoning was that in agreeing to work the ship home, Stilk and the other crew members had not provided any new consideration. They were already bound by their original contract to do everything necessary in the emergencies of the voyage to ensure the ship's safe return. The desertion of a small part of the crew was considered one such emergency. Therefore, the promise to work the ship home was merely a promise to perform an existing duty. As no new consideration was given for the captain’s promise of extra pay, that promise was unenforceable. This established a strict rule that has been heavily debated and was later refined in cases like Williams v Roffey Bros [1991] 1 QB 1, which introduced the concept of 'practical benefit' as a potential exception.
Conclusion
The five cases discussed demonstrate the core principles and complexities of the doctrine of consideration. Currie v Misa provides the classic legal definition, establishing consideration as a benefit to one party or a detriment to the other. This requirement of a bargain is central to English contract law. The decision in Chappell v Nestle reinforces this by showing that the law is not concerned with the 'adequacy' of the bargain; as long as what is given has some value in the eyes of the law, it is 'sufficient'. Carlill v Carbolic Smoke Ball Co illustrates how the doctrine adapts to unilateral contracts, where the consideration is the performance of a requested act.
However, the cases also reveal areas where the doctrine has been criticised for being overly rigid. The rule in Stilk v Myrick, that performance of an existing duty is not good consideration, can appear to defeat reasonable commercial expectations where a party agrees to pay more to ensure a contract is completed. The subsequent development of the 'practical benefit' principle in Williams v Roffey Bros shows the courts attempting to moderate this strict rule to achieve more commercially sensible outcomes. Similarly, the principle that consideration must move from the promisee, as established in Tweddle v Atkinson, led to the harsh privity rule, which prevented a person from enforcing a contract made for their benefit. This was widely seen as unjust and was eventually reformed by Parliament through the Contracts (Rights of Third Parties) Act 1999.
In conclusion, the doctrine of consideration acts as a crucial test for the enforceability of promises. It ensures that only bargains are upheld by the courts, not gratuitous undertakings. As the selected cases illustrate, it has a clear and logical foundation. Yet, its application has sometimes led to strict and inflexible outcomes, prompting both judicial refinement and legislative intervention to ensure the law remains fair and aligned with modern commercial practice.
