Fig. 1The type of misrepresentation, fixed by the maker's state of mind, determines the remedy available.

Key points

A misrepresentation is an untrue statement of fact (or law) made by one party to the other before or at the time of contracting, which induces the other to enter the contract. It is a vitiating factor: it does not usually make the contract void, but voidable, so that the misled party may rescind it. To be actionable the statement must be one of fact, not a mere statement of opinion (Bisset v Wilkinson (1927), where a genuine opinion as to a farm's capacity was not a misrepresentation) unless the maker had special knowledge (Smith v Land and House Property Corporation (1884)), and not a mere sales puff. Silence is generally not a misrepresentation, but there are exceptions - for example where a change of circumstances falsifies an earlier true statement (With v O'Flanagan (1936)) or where a half-truth misleads. The statement must have induced the contract - the misled party must have relied on it.
Misrepresentation is classified by the state of mind of the person who made it, which affects the remedy. A fraudulent misrepresentation is a false statement made knowingly, without belief in its truth, or recklessly as to whether it is true (Derry v Peek (1889)); it allows rescission and damages in the tort of deceit. A negligent misrepresentation is one made without reasonable grounds for believing it to be true; under section 2(1) of the Misrepresentation Act 1967 the person misled may claim damages unless the representor proves that they had reasonable grounds to believe, and did believe, the statement was true - a reversal of the burden of proof that favours the claimant (Howard Marine and Dredging v Ogden (1978)). An innocent misrepresentation is one made with reasonable grounds for belief; the remedy is rescission, or damages in lieu of rescission at the court's discretion under section 2(2).
The principal remedy for misrepresentation is rescission - setting the contract aside and restoring the parties, so far as possible, to their pre-contract positions. Rescission is an equitable remedy and may be lost (barred) where the misled party has affirmed the contract, where too much time has passed, where third parties have acquired rights, or where restitution is no longer possible. Damages may also be available, on the different bases described above.
For evaluation, the law of misrepresentation protects the reliance parties place on statements made during negotiations, and the reversed burden of proof under section 2(1) of the Misrepresentation Act 1967 is a significant protection for the misled party. But the distinctions between the categories, and the different measures of damages, are complex, and the availability of rescission is hedged with bars. A strong answer establishes an actionable misrepresentation, classifies it, and identifies the appropriate remedy.
Worked example

Worked problem question: misrepresentation

D, selling a business, tells C its accounts are accurate when D has not checked and had no reasonable grounds to say so; C buys in reliance and suffers loss. Advise on misrepresentation and remedies.

  1. 01Issue

    Whether D made an actionable misrepresentation and what remedy C has.

  2. 02Rule / authority

    A misrepresentation is a false statement of fact inducing the contract; a negligent misrepresentation under s.2(1) Misrepresentation Act 1967 makes D liable in damages unless D proves reasonable grounds for belief; the misled party may also rescind.

  3. 03Application

    D's statement of fact about the accounts was untrue and induced C to contract. As D had no reasonable grounds to believe it, it is a negligent misrepresentation under s.2(1); D bears the burden of proving reasonable belief and cannot. C may rescind and claim damages under s.2(1).

  4. 04Conclusion

    C can rescind the contract and recover damages for negligent misrepresentation under s.2(1) of the Misrepresentation Act 1967.

Result: The answer establishes a false statement of fact inducing the contract and applies the s.2(1) negligent-misrepresentation regime and its remedies.

Exam focus

  • Be able to establish an actionable misrepresentation (a false statement of fact inducing the contract - Bisset v Wilkinson) and classify it as fraudulent (Derry v Peek), negligent (s.2(1) Misrepresentation Act 1967) or innocent.
  • Explain the remedies - rescission and damages - and the bars to rescission.

Typical mistakes

  • Treating a genuine statement of opinion or a sales puff as a misrepresentation; it must be a false statement of fact (Bisset v Wilkinson).
  • Overlooking the reversed burden of proof for negligent misrepresentation under s.2(1) Misrepresentation Act 1967.

§ 02

Economic duress#

●●○StandardLPAQA 7162/3 - Vitiating factorsLPDfE GCE Law subject content

Key points

Duress is illegitimate pressure applied to a person to make them enter a contract, and it renders the contract voidable. Traditionally duress concerned threats to the person, but the courts have recognised economic duress - illegitimate commercial pressure - as a vitiating factor. It typically arises where one party threatens to break an existing contract, or to withhold performance, unless the other agrees to new or more onerous terms, and the other party has no realistic practical alternative but to agree.
For economic duress the pressure must be illegitimate and must be a significant cause of the innocent party entering the contract. In Pao On v Lau Yiu Long (1980) the Privy Council identified factors relevant to whether pressure amounts to duress: whether the party coerced protested, whether they had an alternative course such as an adequate legal remedy, whether they had independent advice, and whether they took steps to avoid the contract afterwards. In Universe Tankships of Monrovia v International Transport Workers' Federation (1983) the House of Lords confirmed that economic pressure can amount to duress where it is illegitimate and the victim has no real choice, and in Atlas Express v Kafco (1989) a threat to stop deliveries unless a higher price was paid, made to a company that had no practical alternative, amounted to economic duress.
Economic duress must be distinguished from the legitimate commercial pressure that is a normal feature of business negotiations; the mere fact that one party drove a hard bargain is not duress. The key is that the pressure is illegitimate - usually a threatened breach of contract or unlawful act - and that it leaves the victim no reasonable alternative. Where economic duress is established the contract (or the variation) is voidable, so the innocent party may set it aside, subject to bars similar to those for rescission.
For evaluation, the recognition of economic duress is an important protection against the abuse of superior bargaining power, and it complements the rules on consideration in policing the modification of contracts. The difficulty lies in distinguishing illegitimate pressure from hard but lawful bargaining, which makes the boundaries of the doctrine uncertain. A strong answer identifies the illegitimate pressure, applies the Pao On factors, and concludes whether the contract is voidable for economic duress.
Worked example

Worked problem question: economic duress

D, mid-contract, threatens to stop essential deliveries unless C agrees to pay substantially more; C, with no alternative supplier in time, agrees. Advise on whether C is bound.

  1. 01Issue

    Whether the variation is voidable for economic duress.

  2. 02Rule / authority

    Economic duress arises from illegitimate pressure (typically a threatened breach) that is a significant cause of agreement and leaves no practical alternative (Pao On v Lau Yiu Long (1980); Atlas Express v Kafco (1989)).

  3. 03Application

    D's threat to break the existing contract is illegitimate pressure. C had no realistic alternative supplier in the time available, so the pressure left no practical choice and was a significant cause of C's agreement, as in Atlas Express v Kafco.

  4. 04Conclusion

    The variation is voidable for economic duress, so C may set it aside and is not bound to pay the increased price.

Result: The answer identifies illegitimate pressure and the absence of a practical alternative and concludes the variation is voidable.

Exam focus

  • Be able to establish economic duress - illegitimate pressure that is a significant cause and leaves no practical alternative (Pao On; Atlas Express v Kafco).
  • Distinguish illegitimate pressure from legitimate hard bargaining and explain that the contract becomes voidable.

Typical mistakes

  • Treating any strong commercial pressure as duress; the pressure must be illegitimate and leave no practical alternative.
  • Assuming economic duress makes a contract void; it makes it voidable, subject to bars similar to rescission.

Active revision

A supplier, knowing the buyer is desperate, threatens to withhold an essential delivery unless the buyer agrees to a much higher price, and the buyer agrees. Advise on economic duress.

§ 03

Discharge of a contract#

Fig. 2A contract ends by performance, agreement, breach or frustration.

Key points

A contract may be discharged - the parties released from their obligations - in four main ways: by performance, by agreement, by breach, and by frustration. The general rule for discharge by performance is that performance must be complete and exact: under the entire obligations rule, a party who does not perform completely is entitled to nothing (Cutter v Powell (1795), where a sailor who died before completing a voyage earned no wages). This strict rule is softened by exceptions: where a party has substantially performed, they may claim the contract price less the cost of remedying the defects (Hoenig v Isaacs (1952)); where obligations are divisible; where one party is prevented from completing by the other (Planché v Colburn (1831)); and where the other party has freely accepted partial performance (Sumpter v Hedges (1898), where there was no such free acceptance).
Discharge by agreement occurs where both parties agree to release each other, which itself requires consideration (or a deed) unless the contract is wholly executory. Discharge by breach arises where a party commits a repudiatory breach - a breach of a condition, or a sufficiently serious breach of an innominate term - which entitles the innocent party to treat the contract as at an end and claim damages; the innocent party may instead affirm and keep the contract alive. An anticipatory breach, where one party indicates in advance that they will not perform, allows the innocent party to sue immediately without waiting for the date of performance (Hochster v De La Tour (1853)).
Discharge by frustration occurs where, after the contract is formed, an event beyond the parties' control makes performance impossible, illegal, or radically different from what was undertaken. The classic case is Taylor v Caldwell (1863), where the destruction of a music hall frustrated a contract to hire it. In Krell v Henry (1903) the cancellation of a coronation procession frustrated a contract to hire a room to view it, because the common purpose had disappeared. Frustration is narrow: mere hardship, inconvenience or a bad bargain is not enough (Davis Contractors v Fareham Urban District Council (1956)), and it does not apply where the frustrating event is self-induced (Maritime National Fish v Ocean Trawlers (1935)). The Law Reform (Frustrated Contracts) Act 1943 adjusts the parties' positions after frustration, allowing the recovery of money paid, relieving future obligations, and permitting allowances for expenses incurred and valuable benefits conferred.
For evaluation, the strictness of the entire obligations rule can cause hardship, which the exceptions only partly relieve, and the doctrine of frustration is deliberately narrow to prevent parties escaping bad bargains, at the cost of leaving some genuinely disrupted contracts without relief. The Law Reform (Frustrated Contracts) Act 1943 is generally regarded as a fair mechanism for adjusting losses. A strong answer identifies the mode of discharge in issue and applies its rules to the facts.
Worked example

Worked problem question: frustration

C hires D's hall for a concert; before the date, the hall is destroyed by an accidental fire. Advise on whether the contract is discharged.

  1. 01Issue

    Whether the destruction of the hall discharges the contract by frustration.

  2. 02Rule / authority

    A contract is frustrated where an unforeseen event beyond the parties' control makes performance impossible (Taylor v Caldwell (1863)); the Law Reform (Frustrated Contracts) Act 1943 then adjusts the parties' positions.

  3. 03Application

    The accidental destruction of the hall makes performance impossible and is beyond the parties' control, so the contract is frustrated on the Taylor v Caldwell principle. Under the 1943 Act, money paid in advance is recoverable and future obligations are discharged, subject to allowances for expenses.

  4. 04Conclusion

    The contract is discharged by frustration, and the parties' positions are adjusted under the Law Reform (Frustrated Contracts) Act 1943.

Result: The answer applies the doctrine of frustration and the statutory adjustment of the parties' positions.

Exam focus

  • Be able to apply the entire obligations rule and its exceptions (Cutter v Powell; Hoenig v Isaacs; Sumpter v Hedges), and the rules on breach, anticipatory breach (Hochster) and frustration (Taylor v Caldwell; Krell v Henry; Davis Contractors).
  • Explain the effect of the Law Reform (Frustrated Contracts) Act 1943 on the parties' positions after frustration.

Typical mistakes

  • Treating any interruption or hardship as frustration; frustration is narrow and excludes mere hardship or a bad bargain (Davis Contractors).
  • Applying frustration to a self-induced event; frustration must be beyond the parties' control (Maritime National Fish).

Active revision

A venue hired for a specific event is destroyed by fire before the event. Advise on whether the contract is discharged and the parties' positions.

Fig. 3A loss is recoverable if it arises naturally or was within both parties' contemplation, subject to the duty to mitigate.

Key points

The usual remedy for breach of contract is an award of damages, a common-law remedy available as of right. The aim of contract damages is to put the claimant, so far as money can, in the position they would have been in had the contract been properly performed - protecting the claimant's 'expectation' or loss of bargain. This differs from the tort measure, which looks backward to the position before the wrong. The claimant may alternatively claim reliance losses (wasted expenditure), and in certain contracts whose purpose is enjoyment, damages for distress and disappointment are available (Jarvis v Swans Tours (1973), a spoiled holiday).
Damages are limited by the rules on causation and remoteness. The leading case is Hadley v Baxendale (1854), which lays down two limbs: the claimant can recover losses that arise naturally, in the ordinary course of things, from the breach; and losses that, though not arising naturally, were within the reasonable contemplation of both parties at the time of contracting as the probable result of a breach, because of special knowledge communicated to the defendant. In Victoria Laundry v Newman Industries (1949) the claimant could recover ordinary lost profits from the late delivery of a boiler but not the profits of an especially lucrative contract of which the defendant was unaware. The claimant is also under a duty to mitigate their loss by taking reasonable steps to reduce it, and cannot recover for losses that reasonable mitigation would have avoided.
A contract may fix the sum payable on breach. A liquidated damages clause - a genuine attempt to pre-estimate the likely loss - is enforceable, but a penalty clause, designed to punish or deter breach rather than to compensate, is not (Dunlop Pneumatic Tyre v New Garage (1915)). The modern approach in Cavendish Square Holding v Makdessi (2015) asks whether the clause imposes a detriment on the party in breach out of all proportion to any legitimate interest of the innocent party in performance. Where damages are inadequate, the court may grant an equitable remedy in its discretion: specific performance, compelling a party to perform (not granted for personal-service contracts or where damages suffice); an injunction restraining a breach; rescission; or rectification of a mistaken document.
For evaluation, the compensatory, expectation-based measure and the Hadley v Baxendale remoteness rules are generally regarded as fair and predictable, balancing full compensation against the need to keep liability within the parties' contemplation. The penalty rule protects against oppressive clauses, though the Cavendish reformulation has made its application more flexible and less certain. A strong answer assesses damages using the expectation measure and the two limbs of Hadley v Baxendale, considers mitigation, and identifies any equitable remedy.
Worked example

Worked problem question: assessing contract damages

D delivers essential equipment late; C loses its normal trading profits during the delay and also a specially lucrative contract of which D was unaware. Advise on the damages recoverable.

  1. 01Issue

    Which of C's losses are recoverable under the rules on remoteness.

  2. 02Rule / authority

    Damages protect the expectation interest and are limited by Hadley v Baxendale (1854): losses arising naturally (first limb) and losses within both parties' reasonable contemplation through special knowledge (second limb); Victoria Laundry v Newman Industries (1949).

  3. 03Application

    The ordinary lost profits arise naturally from late delivery and are recoverable under the first limb. The profit on the exceptional contract was not within D's reasonable contemplation because D had no knowledge of it, so it is too remote under the second limb, as in Victoria Laundry.

  4. 04Conclusion

    C can recover the ordinary lost profits but not the profit on the exceptional contract, which is too remote for want of special knowledge.

Result: The answer applies the two limbs of Hadley v Baxendale to separate recoverable from irrecoverable losses.

Exam focus

  • Be able to assess damages on the expectation measure and apply the two limbs of Hadley v Baxendale (Victoria Laundry) and the duty to mitigate.
  • Distinguish enforceable liquidated damages from unenforceable penalties (Dunlop; Cavendish v Makdessi) and identify the equitable remedies (specific performance, injunction).

Typical mistakes

  • Using the tort measure (restoring the pre-contract position) for contract damages; contract damages protect the expectation (as-if-performed) position.
  • Recovering unusual losses under Hadley v Baxendale without the special knowledge required by the second limb (Victoria Laundry).
