Contract law (2022): Rights of third parties: Privity of contract

The doctrine of privity of contract is a common law principle which provides that a contract cannot confer rights or impose obligations upon any person who is not a party to the contract. 

The premise is 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 because of its implications for contracts made for the benefit of third parties who are unable to enforce the obligations of the contracting parties. In England and Wales, the doctrine has been substantially weakened by the Contracts (Rights of Third Parties) Act 1999, which created a statutory exception to privity (enforceable third-party rights). 

Third party rights. 

Privity 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 corporation. 

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: for instance, in Donoghue v Stevenson – a friend of Ms. Donoghue bought her a bottle of ginger beer, which contained the partially decomposed remains of a snail. Since the contract was between her friend and the shop owner, Mrs. Donoghue could not sue under the contract, but it was established that the manufacturer was in breach of a duty of care owed to her. Accordingly, she was awarded damages in the tort of negligence for having suffered gastroenteritis and "nervous shock".
