Economic Duress (OCR A-Level Law): Revision Notes
Economic Duress
What is economic duress?
Economic duress is a vitiating factor that allows a contract to be set aside when one party has been forced into the agreement through improper financial threats. Unlike normal commercial negotiations, economic duress involves pressure so severe that it removes the victim's genuine freedom to choose.
The doctrine recognises that where a party enters a contract because they have been coerced through threats to their economic position, they lack real consent. Such an agreement cannot be considered a true bargain between the parties.
The foundational definition comes from Kerr J in The Siboen and The Sibotre (1976), who described economic duress as:
such a degree of coercion that the other party was deprived of his free consent and agreement
This definition establishes that economic duress requires more than simple pressure—it must reach a level where the victim's ability to make a free choice is fundamentally compromised.
Essential elements of economic duress
To successfully claim economic duress, the victim must establish two distinct elements:
- Coercion of the will
- Illegitimate pressure
Both elements must be present for a successful claim.
Coercion of the will
Coercion of the will means the victim's freedom to choose was so restricted that they had no realistic alternative but to agree to the demand. The courts examine several factors when assessing whether coercion occurred.
In Pao On v Lau Yiu Long (1980), the Privy Council established key indicators that courts should consider:
- Whether the victim protested at the time of the agreement
- Whether alternative courses of action were available to the victim
- Whether the victim received independent legal advice before agreeing
- Whether the victim attempted to avoid the pressure or seek help
These factors help courts distinguish between situations where a party reluctantly accepts terms as part of normal business negotiations, and situations where genuine coercion has occurred.
The Universal Sentinel (1983) provides another helpful definition, describing economic duress as arising from:
submission arising from the realisation that there is no other practical choice open to them
In this case, a trade union threatened to blacklist a ship unless a release fee was paid. The court found this constituted economic duress because the ship owner had no realistic alternative—without the release, the ship could not operate commercially.
Illegitimate pressure
Illegitimate pressure means the type of threat used must be improper. This element is crucial because it prevents every hard-fought business negotiation from being challenged as duress.
The courts recognise that commercial pressure is a normal part of business life. Tough negotiations, hard bargaining, and driving advantageous deals are all legitimate business practices. The pressure must cross the line into illegitimate conduct before it can constitute duress.
Examples of illegitimate pressure include:
Threats to breach existing contracts: In Atlas Express v Kafco (1989), a large delivery firm threatened to stop deliveries to a small supplier just before Christmas unless they agreed to pay increased rates. The court held this was economic duress because:
- The timing was deliberately chosen to maximise pressure
- The small firm had no time to find alternative suppliers
- The threat involved breaching the existing contract
- The larger firm was exploiting its dominant position
Threats from trade unions or federations: The Universal Sentinel (1983) confirmed that economic duress can arise from pressure by organisations like trade unions, not just from the other contracting party directly.
Exploitation of financial vulnerability: In DC Builders v Rees (1965), the defendant knew the builders were in severe financial difficulty and facing bankruptcy. They offered to pay only £300 of the £462 owed, knowing the builders had no choice but to accept. The Court of Appeal held this was coercion because there was no true agreement between the parties—the builders only accepted because of their desperate situation.
The distinction between legitimate and illegitimate pressure
It is sometimes difficult to identify where the boundary lies between acceptable commercial pressure and illegitimate coercion. The courts must balance the need to protect vulnerable parties against the importance of allowing robust commercial negotiations.
Williams v Roffey Bros (1991) illustrates legitimate commercial pressure. Builders voluntarily offered additional payment to subcontractors to ensure work was completed on time. Although the subcontractors were in financial difficulty, there was no economic duress because:
- The builders made a reasonable commercial choice
- There was no threat or improper pressure
- The agreement provided practical benefits to both parties
- The builders acted of their own initiative
This case demonstrates that not every agreement made under financial pressure constitutes duress—the pressure must be illegitimate in nature.
Remedies for economic duress
Voidable contract
Where economic duress is established, the contract becomes voidable. This means the contract is valid unless and until the injured party chooses to set it aside.
The injured party has the right to rescission—that is, to have the contract cancelled and to be restored to their pre-contractual position. However, this right is not absolute.
Time limits and affirmation
The victim must seek rescission as soon as reasonably possible after the economic duress has ended. Delay may be treated as affirmation of the contract, meaning the victim is treated as having accepted it despite the duress.
The Atlantic Baron (1979) demonstrates this principle clearly. A shipbuilder demanded a 10% price increase during construction of a tanker, and the buyer agreed. However, the buyer waited eight months after delivery before claiming economic duress to recover the extra payment.
Although the court accepted that there had probably been economic duress, the claim failed because:
- The eight-month delay was excessive
- The buyer had affirmed the contract through their conduct
- They had accepted the increased price for too long
This shows victims must act promptly or risk losing their right to set the contract aside. Delay can be fatal to a duress claim even where duress is otherwise established.
Damages in tort
Because economic duress is similar to the tort of intimidation, the injured party may also claim damages to compensate for losses suffered. This provides an alternative or additional remedy beyond simply setting aside the contract.
Exam technique: analysing economic duress scenarios
When answering problem questions on economic duress, follow this structured approach:
1. Identify the threat: What pressure was applied? Was it a threat to breach a contract, to withdraw services, or to take other action?
2. Assess coercion of the will:
- Did the victim protest?
- Were there alternative options available?
- Did they seek independent advice?
- Did they attempt to resist or avoid the pressure?
3. Determine if pressure was illegitimate:
- Was this normal commercial pressure or improper coercion?
- Did the threat involve unlawful or improper conduct?
- Was there exploitation of vulnerability?
4. Consider timing and affirmation:
- Did the victim act promptly to challenge the contract?
- Or did they delay and potentially affirm it?
5. Identify appropriate remedies:
- Rescission (if claimed promptly)
- Damages in tort
Key cases summary

|---|---|---|
| The Siboen and The Sibotre (1976) | Ship charterers demanded contract renegotiation during recession | Established definition: economic duress is coercion that deprives a party of free consent and agreement |
| Pao On v Lau Yiu Long (1980) | Party refused to complete main contract unless subsidiary agreements were met | Set out factors courts consider: protest, alternatives, independent advice, steps to avoid duress |
| The Universal Sentinel (1983) | Ship blacklisted unless release fee paid to union | Economic duress can include pressure from trade unions; submission from having no other practical choice |
| Atlas Express v Kafco (1989) | Large firm threatened small supplier with stopping deliveries just before Christmas unless higher prices paid | Threat by larger firm to breach contract can be economic duress, especially when exploiting timing and vulnerability |
| Williams v Roffey Bros (1991) | Builders voluntarily offered extra payment to subcontractors | No economic duress where party makes reasonable commercial choice without improper pressure |
| The Atlantic Baron (1979) | Shipbuilder demanded price increase; buyer waited eight months before claiming duress | Delay in challenging contract may amount to affirmation, defeating duress claim |
| DC Builders v Rees (1965) | Defendant exploited builder's financial difficulties to pay reduced amount | Exploitation of financial vulnerability constitutes coercion; no true agreement where party forced to accept due to desperate situation |
Remember!
Key Points to Remember:
- Economic duress requires two elements: coercion of the will AND illegitimate pressure
- Commercial pressure alone is not enough—the pressure must be improper or illegitimate
- Courts consider whether the victim protested, had alternatives, received independent advice, or attempted to avoid the pressure
- Successful claims make the contract voidable, allowing for rescission (if claimed promptly)
- Victims must act quickly after the duress ends, or risk affirming the contract through delay
- Damages may be available in tort as economic duress is similar to the tort of intimidation
