“78. Where it is alleged that one contracting party (the defendant) has induced the other contracting party (the claimant) to enter into the contract between them by duress, the case law has laid down that there are two essential elements that a claimant needs to establish in order to succeed in a claim for rescission of the contract. The first is a threat (or pressure exerted) by the defendant that is illegitimate. The second is that that illegitimate threat (or pressure) caused the claimant to enter into the contract. As Lord Goff said, in the context of economic duress, in Dimskal Shipping Co SA v International Transport Workers’ Federation (The Evia Luck) (No 2)[1992] 2 AC 152 , 165: “[I]t is now accepted that economic pressure may be sufficient to amount to duress [which would entitle a party to avoid a contract] provided at least that the economic pressure may be characterised as illegitimate and has constituted a significant cause inducing the plaintiff to enter into the relevant contract …”
“There is little authority supporting the grant of relief where the claimant’s ‘serious disadvantage’ consists only of the difficult circumstances, including financial, in which he finds himself.”
“In almost all past English cases on unconscionable bargains, B has been an individual with a mental weakness such as inexperience, confusion because of old age or emotional strain … But it is not inconceivable that the relevant weakness could be the very weak bargaining position of a company …”
“(1) It is not sufficient to attract the jurisdiction of equity to prove that a bargain is hard, unreasonable or foolish; it must be proved to be unconscionable, in the sense that “one of the parties to it has imposed the objectionable terms in a morally reprehensible manner, that is to say, in a way which affects his conscience” … (2) “Unconscionable” relates not merely to the terms of the bargain but to the behaviour of the stronger party, which must be characterised by some moral culpability or impropriety … (3) Unequal bargaining power or objectively unreasonable terms provide no basis for equitable interference in the absence of unconscientious or extortionate abuse of power where exceptionally, and as a matter of common fairness, “it was not right that the strong should be allowed to push the weak to the wall” … (4) A contract cannot be set aside in equity as “an unconscionable bargain” against a party innocent of actual or constructive fraud. Even if the terms of the contract are “unfair” in the sense that they are more favourable to one party than the other (“contractual imbalance”), equity will not provide relief unless the beneficiary is guilty of unconscionable conduct … (5) “In situations of this kind it is necessary for the plaintiff who seeks relief to establish unconscionable conduct, namely that unconscientious advantage has been taken of his disabling condition or circumstances”.”
“Section 140A is deliberately framed in wide terms with very little in the way of guidance about the criteria for its application, such as is to be found in other provisions of the Act conferring discretionary powers on the courts. It is not possible to state a precise or universal test for its application, which must depend on the court’s judgment of all the relevant facts. Some general points may, however, be made. First, what must be unfair is the relationship between the debtor and the creditor. In a case like the present one, where the terms themselves are not intrinsically unfair, this will often be because the relationship is so one-sided as substantially to limit the debtor’s ability to choose. Secondly, although the court is concerned with hardship to the debtor, subsection 140A(2) envisages that matters relating to the creditor or the debtor may also be relevant. There may be features of the transaction which operate harshly against the debtor but it does not necessarily follow that the relationship is unfair. These features may be required in order to protect what the court regards as a legitimate interest of the creditor. Thirdly, the alleged unfairness must arise from one of the three categories of cause listed at sub-paragraphs (a) to (c). Fourthly, the great majority of relationships between commercial lenders and private borrowers are probably characterised by large differences of financial knowledge and expertise. It is an inherently unequal relationship. But it cannot have been Parliament’s intention that the generality of such relationships should be liable to be reopened for that reason alone.”
