Misrepresentation and Vitiating Factors for SQE1

Contract Law > Misrepresentation and Vitiating Factors

Vitiating factors are circumstances that undermine the validity of an otherwise properly formed contract. Misrepresentation is the most commonly tested vitiating factor on the SQE1, but you also need to understand duress, undue influence and mistake. A contract may appear valid on its face, but a defect in consent or fairness can allow one party to set it aside. Understanding vitiating factors is essential within Contract Law and connects closely to contract terms.

What Are Vitiating Factors?

Candidates frequently lose marks by confusing the three types of misrepresentation and their remedies — a distinction the examiners test repeatedly. Failing to classify correctly or to identify when the burden of proof shifts under s.2(1) leads to wrong answers.

A vitiating factor is something that renders a contract voidable (or, in the case of certain mistakes, void). The contract appears to be formed correctly, but a defect in consent or integrity means one party can challenge its validity.

Misrepresentation is a false statement of fact (not opinion or future intention) made by one party to the other before or at the time of the contract, which induces the other party to enter into the contract. Other vitiating factors include duress, undue influence and mistake.

Key Principles for SQE1

Types of Misrepresentation

Fraudulent Misrepresentation

The representor makes the statement knowing it is false, without belief in its truth, or recklessly as to its truth (Derry v Peek).

  • Remedy:: Rescission and damages in the tort of deceit. The burden is on the claimant to prove fraud.

Negligent Misrepresentation

The representor has no reasonable grounds for believing the statement to be true. Under s.2(1) Misrepresentation Act 1967, the burden is on the representor to prove they had reasonable grounds. This shifts the burden of proof, making it much easier for the claimant.

  • Remedy:: Rescission and/or damages under s.2(1). Damages are assessed on the same basis as fraudulent misrepresentation (Royscot Trust v Rogerson).

Innocent Misrepresentation

The representor had reasonable grounds for believing the statement was true.

  • Remedy:: Rescission only; the court may award damages in lieu of rescission under s.2(2) Misrepresentation Act 1967.

Quick Comparison Table

| Type | Burden of Proof | Remedy Available | |---|---|---| | Fraudulent | Claimant proves fraud (high threshold) | Rescission + damages in tort | | Negligent | Defendant must prove reasonable grounds | Rescission + damages under s.2(1) | | Innocent | Defendant must prove reasonable grounds | Rescission; damages in lieu under s.2(2) |

Bars to Rescission

Even if misrepresentation is proved, rescission may be barred by:

  1. Affirmation — if the innocent party continues to perform the contract or acts inconsistent with setting it aside
  2. Lapse of timeLeaf v International Galleries — if unreasonable delay passes
  3. Impossibility of restitution — if the subject matter cannot be returned in substantially the same state
  4. Third-party rights — if innocent third parties have acquired rights

Exam tip

Section 2(1) is a game-changer in misrepresentation cases. Once the claimant proves the false statement induced the contract, the burden shifts to the representor to prove reasonable grounds for belief. Do not make the claimant bear the burden of proving the defendant knew it was false — that is only needed for fraud.

Duress

Duress is illegitimate pressure that compels a party to enter the contract. Types include:

  • Duress to the person — threats of physical harm
  • Duress to goods — threats to destroy goods
  • Economic duress — illegitimate economic pressure that coerces agreement (DSND Subsea Ltd v Petroleum Geo-Services ASA)

The contract is voidable. The distinction between legitimate commercial pressure (hard bargaining) and illegitimate coercion is critical.

Undue Influence

Undue influence occurs where one party exploits a position of trust or influence over the other.

Actual Undue Influence (Class 1)

Direct proof that one party exercised undue influence over the other. This requires evidence of overt pressure or coercion.

Presumed Undue Influence (Class 2B — Royal Bank of Scotland v Etridge)

Presumed undue influence arises where:

  1. A relationship of trust and confidence exists between the parties, AND
  2. The transaction calls for explanation (is unusual or at significant undervalue)

Common relationships: solicitor/client, parent/child, doctor/patient. The burden shifts to the defendant to prove the transaction was entered into freely and with full understanding.

Key requirement: The innocent party must have received independent legal advice, or the presumption is much harder to rebut.

Common Mistake

Common mistake occurs where both parties share the same fundamental mistake about existing facts. The contract may be void at common law if the mistake renders the subject matter essentially different from what was agreed (Bell v Lever Brothers). The threshold is very high.

Critical distinction: A mistake as to quality (e.g., a painting is a reproduction rather than an original) does not void the contract. Only mistakes as to the existence or fundamental nature of the subject matter void it.

Mutual and Unilateral Mistake

  • Mutual mistake (parties at cross-purposes) may prevent agreement
  • Unilateral mistake (one party knows the other is mistaken) may make the contract void, particularly regarding identity (Shogun Finance Ltd v Hudson)

How This Appears in SQE1 Questions

SQE1 questions often present a pre-contractual statement and ask you to classify it and identify the correct remedy. Examiners test this distinction repeatedly. The key traps include:

  • Confusing the three types of misrepresentation — learn the classification and remedies for each
  • Forgetting the burden of proof shifts under s.2(1) to the representor
  • Missing the bars to rescission — especially affirmation and lapse of time
  • Treating economic duress as ordinary commercial negotiation — there must be illegitimate pressure, not merely hard bargaining
  • Assuming quality mistakes void contracts — only existence/fundamental nature mistakes void at common law

Common Mistakes Students Make

  • Confusing types of misrepresentation — learn the classification and available remedies for each
  • Forgetting that s.2(1) shifts burden to the representor — once the false statement is proved, the defendant must prove reasonable grounds
  • Overlooking bars to rescission — especially affirmation and lapse of time
  • Treating economic duress as ordinary commercial negotiation — there must be illegitimate pressure
  • Assuming mistakes as to quality void contracts — they do not; only existence/fundamental nature mistakes void
  • Missing presumed undue influence — a relationship of trust + transaction calling for explanation is enough

Quick Summary

  • Fraudulent misrepresentation: Statement known to be false or made recklessly. Remedy: rescission + damages. Claimant proves fraud.
  • Negligent misrepresentation: No reasonable grounds for belief. Remedy: rescission + damages. Burden shifts to defendant under s.2(1).
  • Innocent misrepresentation: Reasonable grounds for belief. Remedy: rescission; damages in lieu under s.2(2).
  • Bars to rescission: Affirmation, lapse of time, impossibility of restitution, third-party rights.
  • Duress: Illegitimate pressure. Contract voidable. Distinguish from hard bargaining.
  • Presumed undue influence: Relationship of trust + transaction calling for explanation. Burden shifts to defendant.
  • Common mistake: Only voids if mistake is as to existence/fundamental nature, not quality.

Quick check questions based on this article.

Question 1

Scenario

A business owner is negotiating the purchase of a restaurant. During negotiations, the seller states that the restaurant's annual turnover is "approximately £400,000." The seller bases this statement on the previous year's accounts, which showed a turnover of £395,000. However, the seller is aware that several major corporate clients have since cancelled their regular bookings, which is likely to reduce the turnover significantly in the current year. The buyer, relying on the seller's statement, agrees to purchase the restaurant for £300,000. The buyer does not request access to the restaurant's current financial records or conduct any independent financial due diligence. After completing the purchase, the buyer discovers that the current year's turnover is projected to be only £250,000 due to the lost corporate clients. The buyer seeks to rescind the contract and recover the purchase price. The seller argues that the statement was substantially accurate at the time it was made, as the previous year's turnover was indeed close to £400,000. The sale contract contains an entire agreement clause but no express warranty regarding turnover. The buyer completed the purchase four months ago and has been trading from the premises throughout that period.

Which of the following best describes the buyer's legal position regarding the seller's statement about turnover?

Question 2

Scenario

A small business owner enters into a contract to purchase a commercial printing press from a dealer for £45,000. Before the sale, the dealer tells the business owner that the press is capable of producing 10,000 prints per hour. The dealer knows this figure is based on the manufacturer's specification for the newest model, and that this particular press, which is a refurbished earlier model, has a maximum output of 6,500 prints per hour. The business owner would not have entered into the contract if the true output had been stated. After delivery, the business owner discovers the true output capacity and seeks to rescind the contract. Six months have passed since delivery, during which the business owner used the press daily. The business owner has also made modifications to the press costing £3,000 to adapt it for specialised work. The business owner mentioned at the time of purchase that output speed was crucial because of a large contract with a publishing house. The dealer offered a 12-month warranty on the press, which the business owner accepted. The dealer's sales brochure contained a small-print disclaimer stating that 'all performance figures are approximate and should not be relied upon.' The business owner did not read the brochure before signing the contract.

Is the business owner likely to succeed in rescinding the contract?

Question 3

Scenario

A furniture manufacturer delivers a consignment of bespoke furniture to a retailer under a supply contract. The contract price is £25,000 and the furniture has been made to the retailer's specific design requirements. Upon delivery, the manufacturer refuses to unload the furniture from the delivery vehicle unless the retailer agrees to pay an additional £5,000, claiming that the cost of materials has increased since the contract was agreed. The retailer has customers who have already paid deposits for the furniture and are expecting delivery within the week. The retailer cannot source equivalent bespoke furniture from any other manufacturer within that timeframe. The retailer agrees to pay the additional £5,000 and the manufacturer unloads the furniture. The retailer pays the additional sum under protest. Two weeks later, the retailer seeks to recover the £5,000. The retailer had recently refurbished his showroom at a cost of £15,000, which is unrelated to this transaction.

Which of the following best describes the retailer's legal position?
