Legal Case Summary
Atlas Express Ltd v Kafco (Importers & Distributors) Ltd [1989] 1 All ER 641
Contract – Validity – Economic duress – Agreement
Facts
The Kafco imported basket ware and entered a contract with Atlas to sell and deliver baskets to Atlas retail stores. Atlas tried to negotiate a further term in the contract for a minimum order of £440 per trailer load. Several days later, an Atlas representative turned up to Kafco’s premises with an empty trailer and told Kafco that if the trailer was not returned with £440 worth of goods as the new minimum, the trailer would be driven away unloaded. Kafco reasonably believed they would be unable to negotiate further terms of the contract and thereby sabotaging their opportunity to trade with Atlas, so they felt compelled to sign the agreement and meet the new terms of minimum stock trade. The agreement continued until Kafco sent them money on account and a letter stating they had signed the contract under duress. Atlas sued for the money on account.
Issue
Whether Kafco signed in duress, even though they had honored the contract.
Decision / Outcome
Judgment was awarded in favour of Kafco. Kafco were found to have signed the agreement under economic duress as they felt that in the circumstances they had no alternative but to sign the varied contract. Kafco had not approved the new terms of the agreement (as they had previously rejected the proposed variation) and further, there was no consideration for the new agreement as the variation placed Kafco in a less favourable position financially. Thus, their non-payment of the money of account resulted from the duress.

This case summary accurately reflects the decision in Atlas Express Ltd v Kafco (Importers & Distributors) Ltd [1989] QB 833 (also reported at [1989] 1 All ER 641). Tucker J’s findings on economic duress and absence of consideration remain good law.
The doctrine of economic duress as applied in this case continues to be recognised in English contract law. The leading principles have since been further developed and refined by the Supreme Court in Times Travel (UK) Ltd v Pakistan International Airlines Corporation [2021] UKSC 40, which clarified the boundaries of lawful act duress and confirmed that illegitimate pressure remains central to any duress claim. The core reasoning in Atlas Express v Kafco — that a party subjected to illegitimate commercial pressure with no reasonable alternative but to comply may avoid a varied contract — is unaffected by that later authority. Readers should be aware of Times Travel as important Supreme Court guidance on the wider doctrine of duress, particularly regarding what constitutes illegitimate pressure.
The article contains a minor factual inaccuracy in the facts section: it was Kafco that had the contract to deliver baskets to Woolworths stores (not "Atlas retail stores"), and Atlas was the carrier engaged by Kafco to perform those deliveries. This misstatement does not affect the legal principles discussed but may cause confusion when reading the case in full.
