Introduction
The doctrine of consideration is a cornerstone of the English law of contract. It is the legal principle that requires something of value to be exchanged between the parties to an agreement for that agreement to be legally binding. This "price of the promise" (Pollock, 1950) ensures that the law only enforces bargains, not gratuitous promises or gifts. While the basic concept appears straightforward, its application through centuries of case law has developed a series of rules that can be technical and have been subject to judicial modification and academic criticism. This essay will critically discuss the doctrine of consideration by examining some of its key principles. It will argue that while the doctrine serves a vital function in policing agreements, the rules developed by the courts are not always consistent and have required significant judicial creativity to adapt to modern commercial contexts. This will be demonstrated through a discussion of five key cases which have shaped the rules on the sufficiency of consideration, past consideration, the performance of existing duties, and the part-payment of debts.
Case Law Analysis
Chappell & Co Ltd v The Nestle Co Ltd [1960] AC 87
The Issue The central legal issue in this case was whether items of trivial economic value, specifically used chocolate bar wrappers, could constitute part of the consideration for a contract. The court had to determine if these wrappers were something of value in the eyes of the law, sufficient to support a binding agreement.
Basic Facts of the Case The defendants, Nestlé, ran a sales promotion where they offered to sell customers a gramophone record for one shilling and sixpence, plus three of their chocolate bar wrappers. The claimants, Chappell & Co, owned the copyright to the song featured on the record. Under the Copyright Act 1956, a royalty was payable to the copyright holder based on the 'ordinary retail selling price' of the record. Chappell & Co argued that the price was not just the money but also included the wrappers, and since the wrappers had no fixed value, the 'ordinary retail selling price' could not be determined, meaning Nestlé had breached their copyright. Nestlé argued the wrappers were worthless and not part of the consideration.
The Judgement The House of Lords, by a majority, held that the wrappers were part of the consideration. Lord Somervell famously stated 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 reasoning was that Nestlé had stipulated the wrappers as a requirement for the sale. The fact that they did so indicated that the wrappers were of value to them, as the promotion was designed to increase the sales of their chocolate bars. Therefore, the wrappers were part of the price paid for the record. This case firmly establishes the principle that consideration must be sufficient (i.e., something of value in the eyes of the law) but it absolutely does not need to be adequate (i.e., of equal market value to the promise it is given for). The courts will not inquire into the fairness of the bargain.
Re McArdle [1951] Ch 669
The Issue The Court of Appeal had to decide whether a promise to pay for work that had already been completed could be legally enforced. The key issue was whether an act performed before a promise of payment is made can be considered good consideration for that promise.
Basic Facts of the Case A house was owned jointly by five siblings, who were to inherit it upon their mother’s death. During the mother's lifetime, the wife of one of the siblings, Mrs McArdle, carried out significant improvements and repairs to the property. After the work was finished, all the siblings signed a document addressed to Mrs McArdle, stating: "In consideration of your carrying out certain alterations and improvements to the property… we the beneficiaries… hereby agree that the executors… shall repay to you from the said estate the sum of £488 in settlement of the amount spent on such improvements." When the mother died, the other siblings refused to authorise the payment. Mrs McArdle sued to enforce the promise.
The Judgement The court held that the promise was unenforceable due to a lack of consideration. The judges reasoned that Mrs McArdle’s consideration—the work she had done on the house—was 'past'. She had completed the repairs before the siblings made the promise to pay her. The wording of the document, "in consideration of your carrying out…", misleadingly suggested a future or present act, but the reality was that the work was already done. The rule is that past consideration is not good consideration. The promise was essentially a promise to pay for a gift or a past favour, and without fresh consideration, it was not a binding contract. This case provides a clear illustration of this strict rule, which prevents past voluntary acts from being used to support a later promise.
Stilk v Myrick (1809) 2 Camp 317
The Issue The issue here was whether sailors who agreed to do extra work after some of their crewmates had deserted were entitled to the extra wages they had been promised. Specifically, the court considered if performing an existing contractual duty was good consideration for a new promise from the same contracting party.
Basic Facts of the Case The claimant, a seaman, agreed to sail a ship from London to the Baltic and back for a wage of £5 per month. During the voyage, two of the twelve crew members deserted the ship. The captain was unable to find replacements and promised the remaining crew that he would divide the wages of the two deserters among them if they worked the ship back to London. The claimant agreed and the ship returned safely. The captain then refused to pay the extra money.
The Judgement The court ruled in favour of the captain, finding that there was no consideration for the promise of extra pay. The claimant was already contractually bound to work the ship back to London. The desertion of a small number of the crew was considered a normal emergency of the voyage, and the remaining sailors were simply performing the duties they had originally agreed to. They had not provided anything new of value in exchange for the captain's promise. Lord Ellenborough held that the promise was void for want of consideration. This case established a key rule that performing an existing contractual duty owed to the promisor is not good consideration for a new promise of extra payment from that promisor. This rule is often justified on policy grounds, as it prevents parties from using their position to demand more money for the same work (a form of economic duress).
Williams v Roffey Bros & Nicholls (Contractors) Ltd [1991] 1 QB 1
The Issue This case revisited the rule in Stilk v Myrick. The Court of Appeal had to decide whether a party who promises to make an additional payment for the timely completion of an existing contractual duty receives a "practical benefit" that can count as good consideration.
Basic Facts of the Case The defendants, Roffey Bros, were building contractors with a contract to refurbish a block of 27 flats. They subcontracted the carpentry work to the claimant, Mr Williams, for £20,000. Part-way through the work, Williams got into financial difficulty, partly because the agreed price was too low. Roffey Bros were concerned that Williams would not complete the work on time, which would mean they would incur a penalty for late completion under their main contract. To avoid this, Roffey Bros promised to pay Williams an additional £10,300, at a rate of £575 per completed flat. Williams continued the work but the defendants did not make all the promised extra payments. Williams sued.
The Judgement The Court of Appeal found in favour of Williams, holding that his completion of the existing work could be good consideration for the promise of extra payment. The court distinguished this case from Stilk v Myrick by introducing the concept of ‘practical benefit’. Glidewell LJ stated that if one party (A) has a contract with another party (B) to do work, and A has reason to doubt B will complete, and A then promises B extra payment in return for B's promise to perform on time, and as a result of this promise A obtains a practical benefit (or avoids a disbenefit), then this benefit can be consideration. Here, Roffey Bros’ practical benefits included avoiding the penalty clause in their main contract, avoiding the trouble and expense of finding a new carpenter, and formalising the payment schedule. This decision significantly softened the rigid rule from Stilk v Myrick, showing the courts' willingness to recognise commercial realities where there is no evidence of duress.
Foakes v Beer (1884) 9 App Cas 605
The Issue The House of Lords considered whether a promise to accept part-payment of a debt in full and final settlement of the entire debt was legally binding. The specific legal question was whether the part-payment itself could be good consideration for the promise to forgive the balance.
Basic Facts of the Case Dr Foakes owed Mrs Beer a sum of money following a court judgment. They entered into an agreement where Mrs Beer agreed that if Dr Foakes paid a portion of the debt immediately and the rest in instalments, she would not take any further legal action against him. Dr Foakes duly paid the entire principal amount of the debt according to this new agreement. However, a judgment debt also carries a right to interest. After the principal had been paid off, Mrs Beer sued Dr Foakes for the interest that had accrued on the debt.
The Judgement The House of Lords held that Mrs Beer was entitled to claim the interest. The court affirmed the precedent set in Pinnel's Case (1602), which established that part-payment of a debt on the due date can never be satisfaction for the whole amount. The reasoning was that the promise to pay a smaller sum cannot be consideration for a promise to discharge a larger one, because the promisor is merely doing part of what they were already legally obliged to do. Dr Foakes had not provided any fresh consideration for Mrs Beer’s promise to forgive the rest of the debt (the interest). This decision has been criticised for being commercially unrealistic, as creditors often find it beneficial to accept a smaller sum for a quick settlement rather than risk getting nothing if the debtor becomes insolvent.
Conclusion: Applying the Cases to the Doctrine
The five cases discussed above reveal the complex and sometimes contradictory nature of the doctrine of consideration. On one hand, the doctrine is founded on simple principles seen in cases like Chappell v Nestle, where the courts refuse to measure the adequacy of a bargain, thereby upholding freedom of contract. Similarly, the rule in Re McArdle provides certainty by clearly stating that past acts cannot be used to enforce a later promise, preventing a flood of claims based on favours.
However, the journey from the strict rule in Stilk v Myrick to the more pragmatic approach in Williams v Roffey Bros shows a doctrine under strain. The original rule in Stilk was clear but could lead to harsh results, whereas Williams v Roffey reflects a judicial desire to give effect to commercial agreements made in good faith, recognising that a 'practical benefit' can be just as valuable as a new legal right. Yet, this creates tension. The 'practical benefit' logic from Williams v Roffey appears to directly contradict the ruling in Foakes v Beer, where a creditor who receives part-payment of a debt surely receives a practical benefit, especially if the alternative is the debtor’s bankruptcy. The courts have to date refused to extend the 'practical benefit' principle to cases of part-payment of debt, leaving two conflicting lines of authority. This demonstrates that while consideration is the price of the promise, what the law deems to be a valid 'price' is not always logical or consistent. The cases show a doctrine that, while fundamental, has been stretched and reshaped by judicial hands to balance the need for legal certainty with the realities of commercial practice.
