Duress

Barton v Armstrong [1973] UKPC 2 is an English contract law case relating to duress. It held that a person who agrees to a contract under physical duress may avoid the contract, even if the duress was not the main reason for agreeing to the bargain.

Facts

Mr Barton was the managing director of a company, whose main business was in property development. Its main projects were going through ‘Paradise Waters (Sales) Pty Ltd’. Barton made a deed so the company agreed to pay $140,000 to Armstrong, and buy his shares for $180,000. Mr Armstrong was the chairman of the board.

Street J found Mr Armstrong had threatened to have Mr Barton killed. But the NSW Court of Appeal said Mr Barton failed to discharge the onus that the threat had caused him to make the contract.

Advice

The Privy Council advised that Mr Barton could avoid the contract for being under duress, and it did not matter that he may have agreed to the deal any way. Lord Cross, Lord Kilbrandon and Sir Garfield Barwick held that physical duress does not need to be the main reason, it must merely be one reason for entering an agreement. Lord Cross said the same rule should apply for duress as in misrepresentation, ‘that if Armstrong’s threats were ‘a’ reason for Barton’s executing the deed he is entitled to relief even though he might well have entered into the contract if Armstrong had uttered no threats to induce him to do so…’

Lord Wilberforce and Lord Simon, dissenting jointly, held that while in agreement on the law, there was no duress on the facts, but the threats needed to be at least "a" reason for entering the contract. They held the case,

involves consideration of what the law regards as voluntary or its opposite… Absence of choice… does not negate consent in law; for this the pressure must be one of a kind which the law does not regard as legitimate. Thus, out of the various means by which consent may be obtained - advice, persuasion, influence, inducement, representation, commercial pressure - the law had come to select some which it will not accept as a reason for voluntary action: fraud, abuse of relation of confidence, undue influence, duress or coercion. In this the law, under the influence of equity, has developed from the old common law conception of duress - threat to life and limb - and it has arrived at the modern generalisation expressed by Holmes J - ‘subjected to an improper motive for action’ (Fairbanks v Snow)...

The three tests for physical duress are to, first, ‘show that some illegitimate means of persuasion was used’ and second that ‘the illegitimate means used was a reason (not the reason, nor the predominant reason nor the cliching reason)’ and third that his evidence is ‘honest and accepted’.
