Privity of contract

Privity of contract is the doctrine that a contract cannot, as a general rule, confer enforceable rights or impose contractual liabilities on a person who is not a party to it. Its negative aspect is familiar: A and B cannot by their contract impose a burden on C. That proposition remains fundamental. Its positive aspect was historically more controversial: even where A and B contract with the evident object of benefiting C, C could not sue B at common law merely because the promise was made for C’s benefit. That second proposition has been substantially qualified by the Contracts (Rights of Third Parties) Act 1999.

For Tripos purposes, privity is best understood not as an isolated technical rule, but as a junction between several themes already encountered. From Week 3, consideration explains part of the older law: a third-party beneficiary usually gave no consideration for the promise. From Week 4, construction is central: the 1999 Act asks whether the contract expressly gives C enforcement rights or whether the term purports to confer a benefit on C, subject to contrary intention. From Week 5, exclusion clauses and Himalaya clauses show privity’s commercial importance in multi-party performance chains. From Week 9, public policy reminds us that contract law must decide when private arrangements should have effects beyond the parties.

The orthodox common law rule produced conspicuous hardship. A widow promised an annuity under a contract between her husband and nephew could not sue personally. A son-in-law for whose benefit two fathers had covenanted could not enforce the covenant. A consignee might wish to sue a stevedore who mishandled goods, although the stevedore was not party to the bill of lading. The law developed devices: agency, trusts of contractual rights, assignment, collateral contracts, tort duties, restrictive covenants in land, specific performance by the promisee, and the doctrine of transferred loss. These devices were often ingenious, but they lacked candour and coherence.

The modern law therefore has two layers. First, the common law rule still matters. It controls burdens; it explains cases outside the 1999 Act; it structures remedies where the promisee rather than the third party sues; and it remains central where parties exclude the Act. Secondly, the Act creates a general statutory route by which an identified third party may enforce a contractual term in specified circumstances. The Act is permissive rather than mandatory: parties may confer rights, withhold rights, or draft out the statutory regime.

In a Cambridge supervision or examination, the strongest answers do not merely recite Tweddle, Dunlop and Beswick. They ask four questions. Who is suing? What right is being enforced? Was that claimant party to the contract or brought within an exception? If the claimant has no direct right, can the promisee recover substantial damages or specific relief? The best essays also distinguish privity from consideration. They overlap historically, but they are not identical. A third party may be a stranger to consideration; a contracting promisee may have provided consideration yet suffer no personal financial loss. Much of the modern law is an attempt to solve that latter remedial problem without abandoning the former structural principle.

The history of privity is not a straight line from error to enlightenment. Early common law did not always draw a sharp distinction between the party to whom a promise was made and the person for whose benefit it was made. By the nineteenth century, however, the doctrine had crystallised around two propositions: only a party to a contract may sue on it; and consideration must move from the promisee. The leading nineteenth-century authority is Tweddle v Atkinson, where the intended beneficiary of a marriage settlement could not enforce promises made between his father and father-in-law. The case came to stand for the proposition that a stranger to the consideration cannot sue, even if the contract was made for his benefit.

The doctrine was then entrenched by the House of Lords in Dunlop Pneumatic Tyre Co Ltd v Selfridge & Co Ltd. Dunlop sold tyres to a distributor on terms designed to maintain resale prices. The distributor obtained a corresponding undertaking from Selfridge, but Dunlop was not party to that later contract. The House of Lords held that Dunlop could not enforce it. Viscount Haldane LC treated privity and consideration as cardinal principles. The result fitted the classical model of contract: contractual liability is voluntarily assumed to a counterparty; contractual rights are correlative to the bargain; and consideration marks the legal boundary of enforceability.

Yet the classical model was ill-suited to many commercial and family arrangements. Contracts are often made in networks. Building contracts may involve employers, contractors, sub-contractors, funders, tenants and purchasers. Carriage of goods by sea involves shippers, carriers, consignees, shipowners, stevedores, warehouse operators and insurers. Insurance, pensions and settlements commonly aim to benefit persons who are not signatories. A rule that only the immediate promisee may sue is conceptually clean, but commercially awkward.

The common law responded through exceptions and evasions. Agency allowed a principal to sue where the contracting party acted as agent. Trusts allowed a promisee to hold the benefit of a promise on trust for a third party, though courts were reluctant to infer such a trust from mere benefit. Assignment allowed transfer of existing contractual rights, but could not create rights initially in the third party. Collateral contracts allowed a third party to sue if a separate contract could be found between promisor and third party. In shipping, Himalaya clauses and the Eurymedon device used agency and unilateral contract analysis to extend exclusions and limitations to stevedores. In building cases, transferred loss allowed the promisee to recover damages for loss suffered by a third party in limited circumstances.

The most visible pressure point was remedial. Suppose A contracts with B for B to confer a benefit on C. B breaches. C, under the old law, cannot sue. A can sue, because A is party to the contract, but A may have suffered no personal financial loss. If A is awarded only nominal damages, B’s promise becomes practically unenforceable. If A recovers substantial damages measured by C’s loss, the compensatory principle is strained, but the contractual allocation of risk is vindicated. Beswick v Beswick exposed that tension. The widow could obtain relief as administratrix of her husband’s estate, but not in her personal capacity. The House of Lords used specific performance to reach a just result, but the conceptual difficulty remained.

Reform was repeatedly proposed. The Law Commission’s Report No 242 identified the old rule as causing injustice, defeating legitimate expectations, producing complexity, and requiring artificial exceptions. Parliament responded with the Contracts (Rights of Third Parties) Act 1999. The Act did not abolish privity. It made a controlled inroad into the third-party beneficiary rule while preserving the prohibition on imposing burdens and preserving party autonomy through construction and opt-out provisions. The historical lesson is therefore not that privity disappeared, but that it moved from an absolute barrier to a default rule within a more candid statutory framework.

1. Privity concerns enforceability, not validity. A contract between A and B may be valid even though it benefits C. The issue is whether C can enforce it. Conversely, the fact that C cannot enforce the contract at common law does not make the contract void. A promisee may still sue; the question then becomes what remedy the promisee can obtain.

1. The burden rule remains strict. A contract cannot impose a contractual obligation on a third party without that person’s consent. If A and B agree that C must pay £10,000 or must perform services, C is not bound merely because A and B have so agreed. This proposition is not displaced by the 1999 Act, which concerns enforcement of benefits by third parties, not imposition of liabilities upon them. It reflects both autonomy and fairness: contractual liability is justified by consent, undertaking, or a legally recognised substitute such as agency.

1. At common law, a third-party beneficiary could not sue merely as beneficiary. Tweddle and Dunlop express the traditional rule. The reason was often put in terms of consideration: the third party had not furnished the price of the promise. But the deeper reason is privity: the promise was not made to the third party as contracting party. A claimant must therefore identify either party status or a recognised route around the rule.

1. The 1999 Act creates the principal modern exception. Under section 1, a third party may enforce a term if the contract expressly provides that he may, or if the term purports to confer a benefit on him, unless on proper construction the parties did not intend enforceability. The third party must be expressly identified by name, class, or description, but need not exist when the contract is made. A contract may therefore confer rights on future employees, future purchasers, family members, or members of an identified class, provided the statutory conditions are met.

The leading cases show a movement from formal exclusion to controlled accommodation of third-party interests.

Tweddle v Atkinson is the classical starting point. Two fathers agreed to pay money to the husband of a newly married couple. The husband was the intended beneficiary, but not a party to the agreement and had provided no consideration. His claim failed. The case is often taught as consideration doctrine, but it is equally a privity case: the claimant sought to enforce a promise not made to him as contracting party.

Dunlop entrenched the doctrine at the highest level. Dunlop’s resale price maintenance scheme failed because Dunlop was not party to the undertaking given by Selfridge to the distributor. Agency was argued but rejected on the facts. The case supplied the canonical statement that only a person who is party to a contract may sue on it, and that consideration must move from the promisee.

Beswick exposed the remedial weakness of the old rule. A nephew promised his uncle that he would pay an annuity to the uncle’s widow after the uncle transferred his business. After the uncle died, the nephew refused. The widow could not sue personally, but as administratrix she could enforce the contract and obtain specific performance. The result mitigated injustice, but only because of the widow’s representative capacity. The case is a powerful illustration of why reform was needed.

The Eurymedon is the major shipping exception. A bill of lading contained a clause protecting servants and agents of the carrier. When goods were damaged by stevedores, the Privy Council upheld the stevedores’ reliance on the clause through an analysis involving agency and unilateral contract. The decision is doctrinally elaborate, but commercially intelligible: parties intended the limitation to protect those performing the carriage operation.

Linden Gardens and Darlington concern defective building work and transferred loss. In Linden Gardens, the House of Lords accepted that an employer might recover substantial damages for defective performance even where the property had been transferred, because otherwise the contractor’s breach would go without effective remedy. Darlington applied analogous reasoning where the plaintiff was not the building owner but the transaction contemplated that the works were for another’s benefit.

Panatown is the most difficult modern case. The employer contracted for building works on land owned by a third party, but the owner also had a direct duty of care deed from the contractor. The House of Lords denied the employer substantial damages for the owner’s loss, by majority. The existence of a direct remedy for the third party was decisive for some members of the appellate committee. Panatown therefore limits transferred loss and shows that the law is reluctant to multiply recovery where the contractual structure has provided another route.

Nisshin Shipping v Cleaves was one of the important early interpretations of the 1999 Act. Charterparties provided for commission to be paid to brokers. The brokers were not parties, but were held entitled to enforce the commission clauses under the Act. The case demonstrates the potency of section 1(1)(b): a term providing for payment to a third party naturally purports to confer a benefit, absent contrary intention.

Avraamides v Colwill supplies a caution. The Act requires the third party to be expressly identified by name, class or description in the contract. It is not enough that the contracting parties knew who would be affected. The statutory formalities matter.
