Raffles v. Wichelhaus, 159 Eng. Rep. 375 (Ex. 1864)
Raffles v. Wichelhaus (1864) is one of the most famous cases in contract law, establishing the doctrine that no contract forms when parties attach fundamentally different meanings to a critical term.
When parties attach materially different meanings to an ambiguous term in a contract, and neither party knows or has reason to know of the other's understanding, is there a binding contract?
No contract is formed when both parties attach materially different meanings to an ambiguous term that is essential to the contract, and neither party knows or has reason to know of the other party's different understanding. This is the doctrine of mutual misunderstanding or mutual mistake as to a basic assumption. For a contract to exist, there must be a "meeting of the minds" on essential terms.
The court held that no contract was formed because there was no meeting of the minds regarding which ship Peerless the parties intended. Since each party reasonably understood the term to refer to a different ship, and neither knew of the other's different understanding, there was no mutual assent to the same bargain.
Raffles v. Wichelhaus established the principle that mutual misunderstanding about a material term prevents contract formation, even under the objective theory. The case teaches that while courts generally use an objective standard to interpret contracts, there are limits when ambiguity exists and parties have fundamentally different understandings. This case is foundational in contract law and is distinguished from cases where one party knows or should know of the other's different understanding. It also illustrates the importance of clarity in contract drafting and the consequences of latent ambiguities.
