Consent CASES

In English law, consent refers to the voluntary agreement or permission given by a party, which can significantly affect the legality of actions and the enforceability of agreements.

Definition and principles

Consent must be informed, voluntary, and given freely without coercion, duress, or misrepresentation. Genuine consent is vital to the validity of contracts and certain defences in tort and criminal law.

Factors affecting genuine consent

• Duress: Consent obtained by threats or unlawful pressure is invalid.
• Undue influence: Exploiting a relationship of trust or dependency invalidates consent.
• Misrepresentation: False statements inducing consent can render it voidable.
• Mistake: Fundamental errors can undermine the reality of consent.

Case example: Barton v Armstrong (1973)

In Barton v Armstrong, the Privy Council ruled that consent to a contract is invalid if procured by threats or duress. Even if threats weren’t the sole reason for agreement, their presence sufficiently taints consent, making the contract voidable.

Legal effects of invalid consent

Invalid consent can lead to void or voidable contracts, allowing the affected party to rescind the agreement, claim damages, or seek other remedies depending on circumstances.

Practical importance

Consent remains critical in transactions, contracts, and legal defences, requiring parties to ensure clarity, fairness, and transparency in obtaining and recording consent.
