"The current law of duress and undue influence is so unclear that it creates chaos rather than uncertainty in the law." Discuss.

The area of law concerning defective contracts tainted by duress or undue influence has been created in order to protect those people that enter into a contract which involves high degrees of risks and which has been entered in disadvantageous circumstances. English law does not normally concern itself with the fairness of a bargain but it does recognise that it needs to intervene in some circumstances. Cases based on duress and undue influence are exceptional. It is true that the law in this area is unclear but in order to discuss its effectiveness it is necessary to weigh up both its merits and weaknesses. It will then be possible to decide whether this area of law is chaotic rather than uncertain.

In short, at common law, the doctrines of duress and undue influence allow a contract to be set aside if one party has put unfair and improper pressure on the other in the negotiations leading up to the contract. So, an inequality of bargaining power between contractual parties, which is exploited by the more dominant party, is a basis on which the law may permit the weaker party to rescind that contract.

Duress is the unlawful pressure to perform an act. In Universe Tankships v. ITWF,1 Lord Scarman said that to establish that duress had occurred, it was necessary to establish two things. Firstly, that the victim was subjected to pressure which was illegitimate and secondly, that the pressure exerted on the victim was so great that it gave rise to the compulsion of his/her will. If both these facts are present, the doctrine of duress would render the contract voidable. There are different categories of duress. Duress to the person cases are of little significance, since the number of cases in this area has always been small. Duress to property recognises that a threat to seize another's property or to damage it will justify a claim of duress and result in the ensuing contract being set aside. More recently, the emergence of a new and far more significant doctrine of economic duress has taken place. Due to its comparatively recent development in English law the doctrine is still developing. It therefore contributes to the chaotic nature of this area of the law.

Kerr J in the case of Occidental Worldwide Investment Corporation v Skibs A/S Avanti, The Sibeon and The Sibotre2 first examined the idea of economic duress. A common situation raising the possibility of action for economic duress is where one party threatens to break a contract unless that contract is renegotiated, and the other agrees rather than face disastrous consequences as a result of the breach. This area is fraught with difficulty because companies who deal with each other on a regular basis often voluntarily agree to change the terms of the contract. The economic duress doctrine threatens them. However, the need for a clear and recognised doctrine in English Law has been called for due to changes to the law relating to consideration, particularly concerning variation of commercial contracts.

In Pao On v Lau Yiu Long,3 the Privy Council approved the doctrine of economic duress and attempted to identify its essential ingredients. Two essential conditions for the operation of the doctrine were identified by Lord Scarman. Firstly, there must be a 'coercion of the will that vitiates consent' and secondly, the pressure or threat must be 'illegitimate'.

Pao On involved the sale of shares in a company called Fu Chip. The plaintiffs agreed with the defendants that they would not sell 60% of their shares for one year. The defendants then promised to indemnify the ...
