Illegitimate Pressure CASES

In English contract law, illegitimate pressure refers to threats or coercion that undermine a party’s free consent to an agreement. It is a key element of economic duress and can render a contract voidable.

Definition and Principles

Illegitimate pressure goes beyond hard bargaining. It arises where one party applies unlawful or unconscionable pressure, leaving the other with no practical choice but to agree. The law protects genuine consent while allowing robust commercial negotiation.

Requirements for Establishing

• Pressure: The claimant must show they were subjected to coercion or threats.
• Illegitimacy: The pressure must be unlawful, unconscionable, or contrary to public policy.
• Causation: The pressure must have induced the agreement or variation.
• Lack of practical choice: The claimant must demonstrate they had no realistic alternative but to submit.

Practical Applications

Illegitimate pressure is often alleged in commercial contexts, such as threats to breach an existing contract unless more favourable terms are accepted. Courts distinguish between acceptable commercial pressure and coercion that vitiates consent.

Importance

Recognising illegitimate pressure ensures that contracts rest on free and voluntary agreement. It prevents exploitation while maintaining space for legitimate negotiation and commercial leverage.
