Legal Case Summary
L’Estrange v E. Graucob Ltd [1934] 2 KB 394
Affirmed that the clauses of a written contract are binding on the signatories, even where a party is unaware of the contract’s full contents.
Facts
The claimant, L’Estrange, contracted to purchase a slot machine for cigarettes from the defendant, Graucob, and the agreement included an express clause stating ‘This agreement contains all the terms and conditions under which I agree to purchase the machine specified above and any express or implied condition, statement, or warranty, statutory or otherwise not stated herein is hereby excluded’. The machine proved to be faulty and the claimant thus brought an action against the defendant, alleging that the machine breached the Sale of Goods Act by not being of merchantable quality. The defendant asserted that the statute was made irrelevant by the express clause, and that he was not in breach of the agreement they had made. The claimant responded she had been unaware of the clause as she had not properly read the agreement and it ought not apply.
Issue
Whether the clause excluding all terms not stated in the contract should be deemed effective and binding.
Held
The Court of Appeal found for the defendant, determining that the express provisions of the contract were binding and effectively excluded the relevance of statutory sales provisions. Furthermore, the fact that the claimant had not properly read the contract did not impact its validity, as in signing the contract she consented to be bound by its contents. Significantly this case emphasizes the Court’s respect for sanctity of contract.

This case summary remains accurate as a statement of the common law rule established in L’Estrange v Graucob: a party who signs a contractual document is generally bound by its terms, whether or not they have read them.
However, readers should note an important statutory development that significantly limits the practical reach of this principle in consumer contexts. The Consumer Rights Act 2015 now governs contracts between traders and consumers and substantially restricts the ability to exclude or restrict statutory rights and implied terms (including those equivalent to the former Sale of Goods Act implied terms, now found in ss.9–18 of the 2015 Act). Exclusion clauses of the kind in issue in L’Estrange v Graucob would, in a modern consumer contract, be subject to a fairness assessment under the 2015 Act and could not lawfully exclude the consumer’s statutory rights. The Unfair Contract Terms Act 1977 also continues to apply in business-to-business contexts to limit certain exclusion clauses. The article’s reference to the Sale of Goods Act reflects the law as it stood at the time of the case; the relevant implied terms in consumer sales are now governed by the Consumer Rights Act 2015, and in non-consumer sales by the Sale of Goods Act 1979 (as amended).
The core principle of the case — that a signatory is bound by the terms of a signed document — remains good law, confirmed in subsequent cases including Toll (FGCT) Pty Ltd v Alphapharm Pty Ltd and reaffirmed in domestic authorities, though it operates subject to these statutory constraints and to the general law on misrepresentation and non est factum.
