The doctrine of privity in contract law provides that a contract cannot confer rights or impose obligations arising under it on any person or agent except the parties to it.
This seems to make adequate sense, in that only parties to contracts should be able to sue to enforce their rights or claim damages as such. However the doctrine has proven problematic due to its implications upon contracts made for the benefit of third parties who are unable to enforce the obligations of the contracting parties.
Third-party rightsPrivity of contract occurs only between the parties to the contract, most commonly contract of sale of goods or services. Horizontal privity arises when the benefits from a contract are to be given to a third party. Vertical privity involves a contract between two parties, with an independent contract between one of the parties and another individual or company.
If a third party gets a benefit under a contract, it does not have the right to go against the parties to the contract beyond its entitlement to a benefit. An example of this occurs when a manufacturer sells a product to a distributor and the distributor sells the product to a retailer. The retailer then sells the product to a consumer. There is no privity of contract between the manufacturer and the consumer.
This, however, does not mean that the parties do not have another form of action e.g. Donoghue v. Stevenson -- here a friend of Ms. Donoghue bought her a bottle of ginger beer, which was defective. Specifically, the ginger beer contained the partially decomposed remains of a snail. Since the contract was between her friend and the shop owner, there was no privity of contract, but it was established that the manufacturer has a duty of care owed to their consumers and she was awarded damages in tort.
Privity is the legal term for a close, mutual, or successive relationship to the same right of property or the power to enforce a promise or warranty.
HistoryPrior to 1833 there existed decisions in English allowing provisions of a contract to be enforced by persons not party to it, usually relatives of a promisee. The doctrine of privity emerged alongside the doctrine of consideration, the rules of which state that consideration must move from the promisee. That is to say that if nothing is given for the promise of something to be given in return, that promise is not legally binding unless promised as a deed. 1833 saw the case of Price v. Easton, where a contract was made for work to be done in exchange for payment to a third party. When the third party attempted to sue for the payment, he was held to be not privy to the contract, and as such his claim failed. This was fully linked to the doctrine of consideration, and established as such, with the more famous case of Tweddle v. Atkinson. In this case the plaintiff was unable to sue the executor of his father-in-law, who had promised to the plaintiff's father to make payment to the plaintiff, because he had not provided any consideration to the contract.
The doctrine was developed further in Dunlop Pneumatic Tyre v. Selfridge and Co. Ltd. through the judgement of Lord Haldane.
Privity of Contract played a key role in the development of negligence as well. In the first case of Winterbottom v. Wright (1842), in which Winterbottom, a postal service wagon driver, was injured due to a faulty wheel, attempted to sue the manufacturer Wright for his injuries. The courts however decided that there was no privity of contract between manufacturer and consumer in order to support the Industrial Revolution.
This issue appeared repeatedly until MacPherson v. Buick Motor Co. (1916), a case analogous to Winterbottom v Wright involving a car's defective wheel. Judge Cardozo, writing for the New York Court of Appeals, decided that no privity is required when the manufacturer knows the product is probably dangerous if defective, third parties i.e. consumers will be harmed because of said defect, and there was no further testing after initial sale. Foreseeable injuries occurred from foreseeable uses. Cardozo's innovation was to decide that the basis for the claim was that it was a tort not a breach of contract. In this way he finessed the problems caused by the doctrine of privity in a modern industrial society. Although his opinion was only law in New York State, the solution he advanced was widely accepted elsewhere.
Common law exceptionsThere are exceptions to the general rule, allowing rights to third parties and some impositions of obligations. These are:
- Collateral Contracts (between the third party and one of the contracting parties)
- Trusts (the beneficiary of a trust may sue the trustee to carry out the contract)
- Land Law (restrictive covenants on land are imposed upon subsequent purchasers if the covenant benefits neighbouring land)
- Agency and the assignment of contractual rights are permitted.
Attempts have been made to evade the doctrine by implying trusts (with varying success), constructing the Law of Property Act 1925 s. 56(1) to read the words "other property" as including contractual rights, and applying the concept of restrictive covenants to property other than real property (without success).
Statutory exceptionsThe Contracts (Rights of Third Parties) Act 1999 (UK) now provides some reform for this area of law which has been criticised by judges such as Lord Denning and academics as unfair in places. The act states:
1. - (1) Subject to the provisions of this Act, a person who is not a party to a contract (a "third party") may in his own right enforce a term of the contract if- (a) the contract expressly provides that he may, or (b) subject to subsection (2), the term purports to confer a benefit on him. (2) Subsection (1)(b) does not apply if on a proper construction of the contract it appears that the parties did not intend the term to be enforceable by the third party.
This entails that a person who is named in the contract as a person authorised to enforce the contract or a person receiving a benefit from the contract may enforce the contract unless it appears that the parties intended that he may not.
The Act enables the aim of the parties to be fully adhered too. Taking the situation in Beswick v Beswick whereby the only reason why Mr Beswick and his nephew contracted was for the benefit of Mrs Beswick. Under the Act Mrs Beswick would be able to enforce the performance of the contract in her own right. therefore, the Act realises the intentions of the parties.
The law has been welcomed by many as a relief from the strictness of the doctrine, however it may still prove ineffective in professionally drafted documents, as the provisions of this statute may be expressly excluded by the draftsmen.
Third-party beneficiariesIn Australia, it has been held that third-party beneficiaries may uphold a promise made for its benefit in a contract to which it is not a party (Trident General Insurance Co Ltd v. McNiece Bros Pty Ltd (1988) 165 CLR 107). There were caveats however; the two parties to the contract are able to vary the terms of the contract as they see fit, unless the third-party has relied on the promise, and the promisor is subject to any defences that it would have had, had the promise been enforced by the promisee. It is important to note though that the decision in Trident had no clear ratio.
Although damages are the usual remedy for the breach of a contract for the benefit of a third party, if damages are inadequate, specific performance may be granted (Beswick v. Beswick  AC 59).
The issue of third-party beneficiaries has appeared in cases where a stevedore has claimed it is covered under the exclusion clauses in a bill of lading. In order for this to succeed, four factors must be made out:
- The bill of lading must clearly intend to benefit the third party.
- It is clear that when the carrier contracts with the consignor, it also contracts as an agent of the stevedore.
- The carrier must have had authority by the stevedores to act on its behalf, or the stevedores must later endorse the actions of the carrier.
- Any difficulties with consideration moving from the stevedores must be made out.
The last issue was explored in New Zealand Shipping Co Ltd v. A M Satterthwaite & Co Ltd  AC 154, where it was held that the stevedores had provided consideration for the benefit of the exclusion clause by the discharge of goods from the ship.
New Zealand has enacted the Contracts Privity Act 1982, which enables third parties to sue if they sufficiently identified as beneficiaries by the contract, and in the contract it is expressed or implied they should be able to enforce this benefit.
