Economic Duress (AQA A-Level Law): Revision Notes
Economic duress
What is economic duress?
Economic duress occurs when one party uses threats relating to another person's financial situation to force them into forming or modifying a contract. This is recognised at common law as a vitiating factor – meaning it undermines the validity of a contract because the innocent party has not given genuine consent.
A contract formed under economic duress cannot be considered a true agreement between the parties. The affected party has been coerced rather than freely agreeing to the terms.
The concept was first supported by Kerr J in The Siboen and The Sibotre (1976), where he defined economic duress as:
such a degree of coercion that the other party was deprived of his free consent and agreement
This foundational definition establishes that the level of coercion must be severe enough to eliminate genuine free will.
The two essential requirements
To successfully establish economic duress, a claimant must prove both of the following elements:
1. Coercion of will
This means the victim's will was overborne by the pressure applied. The courts will consider several factors when assessing whether there was coercion of the will:
- Did the victim protest about the pressure at the time?
- Was there an alternative course of action available to them?
- Were they independently advised by lawyers or other professionals?
- Did they take steps to avoid the pressure or try to escape from it?
These factors were established in Pao On v Lau Yiu Long (1980). The more of these factors present, the more likely it is that coercion occurred. Courts will examine each factor holistically to determine whether the victim truly had free choice.
2. Illegitimate pressure
Not all pressure amounts to economic duress. Coercion caused by pressure alone is insufficient – the pressure must be illegitimate. This is crucial because:
- Hard bargaining and tough negotiation are normal in business
- Commercial pressure is a fact of business life
- Simply driving a hard bargain does not make a contract invalid
- Otherwise, every toughly negotiated deal would be at risk of being voided
The pressure must cross the line from acceptable commercial pressure into illegitimate threats or coercion.
Distinguishing economic duress from legitimate commercial pressure
Pressure to negotiate and enter into contracts is normal in business. The difficulty lies in identifying where the line falls between:
- Necessity to contract (legitimate pressure)
- Coercion (illegitimate pressure)
Commercial pressure by itself is not enough to invalidate a contract. The courts have developed principles through case law to help draw this distinction. This ensures that normal business negotiations remain valid while protecting parties from genuine coercion.
The key is determining whether the pressure crossed the boundary from legitimate commercial negotiation into illegitimate threats or exploitation.
Key legal principles from case law
Threats from trade unions and organisations
Economic duress can include pressure from trade unions or other organisations, not just from the other contracting party.
The Universal Sentinel (1983) established that threats by a union to blacklist a ship constituted economic duress. The court described the situation as:
submission arising from the realisation that there is no other practical choice open to them
This demonstrates that the source of pressure is irrelevant – what matters is whether it constitutes illegitimate coercion.
Threats to breach contracts
A threat by one party (especially a larger, more powerful party) to breach an existing contract can constitute economic duress.
In Atlas Express v Kafco (1989), a larger firm threatened a small firm that they would breach their contract. This was held to be economic duress because:
- The small firm had no realistic alternative
- The timing of the threat (just before Christmas) made it impossible to find alternative suppliers
- The larger firm exploited the smaller firm's vulnerability
Exploitation of vulnerability is a key indicator of illegitimate pressure. When one party deliberately takes advantage of another's weak position, especially regarding timing or lack of alternatives, this crosses into economic duress territory.
When economic duress is NOT present
Not every difficult situation amounts to economic duress. In Williams v Roffey Bros (1991), there was no economic duress because:
- The builders had made a reasonable choice to renegotiate
- The decision was made freely
- There was no illegitimate threat or coercion
This case illustrates that voluntary renegotiation based on mutual benefit does not constitute economic duress.
Effect and remedies for economic duress
Effect on the contract
Economic duress makes a contract voidable, not void. This means:
- The contract exists but can be set aside
- The innocent party has a choice whether to proceed or not
- They can choose to affirm or avoid the contract
The distinction between voidable and void is crucial:
- A void contract has no legal effect from the outset
- A voidable contract is valid unless and until the innocent party chooses to set it aside
This gives the victim control over whether to proceed with or rescind the contract.
Available remedies
Rescission is the primary remedy for economic duress. The injured party is entitled to have the contract set aside, which means:
- Both parties are returned to their pre-contractual position
- The contract is treated as if it never existed
- This is only available unless the party has expressly or impliedly affirmed the contract
Critical timing requirement: The injured party must seek rescission as soon as possible after the economic duress has stopped. Delay can be fatal to a claim and may be interpreted as affirmation of the contract.
Damages may also be available. Since economic duress is similar to the tort of intimidation, damages may be claimed in tort law.
Loss of the right to rescind
The right to rescission can be lost if:
- The victim waits too long before taking action
- They affirm the contract (either expressly or by their conduct)
- It becomes impossible to restore the parties to their original positions
Key cases explained
Case: The Siboen and The Sibotre (1976)
Facts: During a worldwide recession, charterers of ships demanded renegotiation of their existing contracts with ship owners.
Legal significance: This case provided the foundational definition of economic duress. Kerr J described it as a degree of coercion so severe that the other party was deprived of their free consent and agreement.
This definition established the threshold that must be met: the coercion must be significant enough to eliminate genuine free will and consent.
Case: Pao On v Lau Yiu Long (1980)
Facts: C refused to complete the main contract unless D met certain subsidiary agreements. D was very anxious for the main contract to be fulfilled.
Legal significance: This case established the key factors courts should consider when assessing whether coercion of the will occurred:
- Whether the victim protested
- Whether they had alternative options available
- Whether they received independent advice
- Whether they took steps to avoid the duress
These factors provide a practical framework for courts to assess the presence of coercion in commercial disputes.
Case: The Universal Sentinel (1983)
Facts: A ship was blacklisted by a shipping workers' federation unless the owner paid a release fee.
Legal significance: This case demonstrated that economic duress can come from third parties (such as trade unions or federations), not just from the other contracting party. The court noted the victim's submission arose from realising they had no other practical choice.
This expanded the scope of economic duress beyond direct contractual relationships.
Case: Atlas Express v Kafco (1989)
Facts: Kafco had won a contract to supply baskets to Woolworths. During performance, the supplier (Atlas Express) raised its delivery prices and threatened to stop deliveries unless Kafco agreed to pay the increase. Kafco reluctantly agreed.
Legal significance: The court held that:
- Kafco was not bound by the agreement to pay the increase
- Atlas raised the price just before Christmas when Kafco had no time to find alternatives
- This exploitation of vulnerability constituted economic duress
- The threat to breach the existing contract was illegitimate pressure
This case demonstrates how timing and lack of alternatives can establish economic duress, especially when one party deliberately exploits these circumstances.
Case: Williams v Roffey Bros (1991)
Facts: Builders made a voluntary offer to pay additional money to ensure work was completed on time.
Legal significance: This case shows the limits of economic duress. There was NO economic duress because:
- The builders had made a reasonable, informed choice
- There was no threat or illegitimate pressure
- The decision was made freely to protect their own interests
- This was legitimate commercial renegotiation
This case establishes that voluntary renegotiation for mutual benefit does not constitute duress, even if one party is under commercial pressure.
Case: The Atlantic Baron (1979)
Facts: H agreed to build a tanker for N. Later, H insisted the price would increase by 10%. N reluctantly agreed but later argued economic duress to recover the extra payment.
Legal significance: While the court accepted there had probably been economic duress, N lost the right to rescission because:
- They waited eight months before taking action
- This delay meant they had affirmed the contract
- This case emphasises the importance of acting promptly
This case serves as a warning: even where economic duress is established, delay in seeking rescission can be fatal to the claim.
Case: DC Builders v Rees (1965)
Facts: DC Builders had carried out work on Rees's house. Rees knew DC Builders was in serious financial trouble and offered to pay only £300 of the agreed £462 owed. DC Builders agreed to avoid bankruptcy.
Legal significance: The Court of Appeal held that:
- Rees had used coercion by exploiting DC Builders' financial vulnerability
- There was no true accord (genuine agreement) between the parties
- The agreement was obtained through illegitimate pressure
- DC Builders could recover the full amount owed
This case illustrates economic duress in the context of payment disputes, where one party deliberately exploits another's desperate financial situation.
Remember!
Key Points to Remember:
- Economic duress requires proof of both coercion of will and illegitimate pressure – both elements must be present
- Not all pressure is illegitimate – tough commercial bargaining is acceptable and normal in business
- Economic duress makes a contract voidable, allowing the innocent party to seek rescission (setting the contract aside)
- Act quickly – the victim must seek rescission as soon as possible after the duress stops, or they risk losing the right (see The Atlantic Baron)
- Economic duress can come from third parties like trade unions (The Universal Sentinel), not just from the other contracting party
- Courts consider multiple factors including whether there were alternative options, independent advice, and whether the victim protested (Pao On v Lau Yiu Long)
Key Terms:
- Economic duress – threats to financial situation to force agreement
- Vitiating factor – something that undermines contract validity
- Voidable – can be set aside but is not automatically void
- Rescission – remedy that restores both parties to their pre-contract position
- Coercion of will – victim's will was overborne
- Illegitimate pressure – pressure that goes beyond acceptable commercial dealings
