Vitiating Factors in Contract Law

Vitiating factors are elements or circumstances that can undermine or invalidate the formation of a contract. These factors affect the validity and enforceability of a contract, potentially rendering it void or voidable. Common vitiating factors include misrepresentation, mistake, duress, undue influence, and illegality. Understanding these factors is crucial for determining whether a contract can be legally enforced or if it can be rescinded.

Misrepresentation

Misrepresentation involves a false statement of fact made by one party to another, inducing the latter to enter into the contract. The statement must be factual, not opinion, and must be a significant factor in the other party's decision to contract. Misrepresentation can be classified into three types:

  • Fraudulent Misrepresentation: Occurs when the false statement is made knowingly, without belief in its truth, or recklessly. Remedies include rescission and damages for deceit.
  • Negligent Misrepresentation: The false statement is made carelessly or without reasonable grounds for belief in its truth. Remedies include rescission and damages under the Misrepresentation Act 1967 or common law negligence.
  • Innocent Misrepresentation: A false statement made without fault. The primary remedy is rescission, and the court may also award damages in lieu of rescission under the Misrepresentation Act 1967.

Mistake

A mistake in contract law refers to an erroneous belief about a fact at the time the contract is formed. Mistakes can be categorized into several types:

  • Common Mistake: Both parties share the same fundamental mistake about a key fact, such as the existence of the subject matter. The contract may be void if the mistake renders the contract impossible to perform.
  • Mutual Mistake: Each party misunderstands the other, resulting in a contract where the parties are at cross-purposes. The contract may be void if there is no agreement on the same terms.
  • Unilateral Mistake: One party is mistaken, and the other party knows or ought to know of the mistake. This can make the contract voidable, especially if it involves the identity of a party or the nature of the agreement.

Duress

Duress involves threats or pressure exerted on a party to enter into a contract against their will. The pressure must be such that it overcomes the party's free will. There are different forms of duress:

  • Physical Duress: Threats of physical harm or actual violence to the person or their loved ones.
  • Economic Duress: Unlawful or illegitimate pressure on a party's economic interests, such as threatening to breach a contract unless more favorable terms are accepted.
  • Duress to Goods: Threats to seize, damage, or withhold goods belonging to the party unless they agree to contract terms.

Undue Influence

Undue influence occurs when one party exerts excessive pressure or influence over another, depriving them of free will in making a contract. It often arises in relationships of trust and confidence. There are two main types:

  • Actual Undue Influence: Direct evidence of coercion or manipulation in the contracting process.
  • Presumed Undue Influence: Arises in certain relationships where one party is in a position of trust (e.g., solicitor and client, doctor and patient), and a rebuttable presumption of undue influence exists.

Illegality

Contracts that involve illegal activities or are against public policy are void and unenforceable. Illegality can arise in various contexts:

  • Statutory Illegality: Contracts that violate statutory provisions are void. For example, a contract for the sale of illegal drugs.
  • Common Law Illegality: Contracts that are contrary to public policy, such as agreements restraining trade unreasonably, are void.

Case Law

Misrepresentation - Smith v Land and House Property Corp (1884)

The court found that a statement made by a seller regarding a tenant's reliability was a misrepresentation, as the tenant was in arrears. This misrepresentation induced the buyer to enter the contract, leading to the contract's rescission.

Mistake - Bell v Lever Brothers Ltd (1932)

This case involved a common mistake where both parties believed an employment contract could be terminated without compensation, unaware of undisclosed breaches. The court held that the contract was not void because the mistake did not fundamentally affect the contract.

Duress - The Atlantic Baron (1979)

The case concerned economic duress where a shipbuilder threatened to breach a contract unless the buyer agreed to a price increase. The court found that the buyer's agreement was made under duress, making the variation voidable.

Examples

Example 1 - Undue Influence

Scenario:

A young adult signs over the title to their property to a financial advisor who has been managing their finances. The advisor, who holds a position of trust, unduly influences the decision. The court may set aside the contract due to presumed undue influence.

Example 2 - Illegality

Scenario:

Two parties enter into a contract to operate a gambling business in a jurisdiction where gambling is illegal. The contract is unenforceable because it involves illegal activities and violates public policy.

Conclusion

Vitiating factors are critical in contract law as they can impact the validity and enforceability of contracts. Misrepresentation, mistake, duress, undue influence, and illegality can render a contract void or voidable, providing grounds for rescission or refusal to enforce the contract. Understanding these factors helps protect parties from unfair or unconscionable agreements and ensures that contracts are formed and performed within the bounds of fairness and legality.
