The doctrine of frustration mitigates the common law’s insistence on literal performance of absolute promises. Moving on from the strict “absolute contracts” rule of Paradine v Jane (1647), the modern doctrine kills the contract automatically and discharges the parties without damages.

The “Radically Different” Test

Originating in Taylor v Caldwell (1863), the doctrine no longer rests on the “implied term” fiction. Per Davis Contractors v Fareham UDC (1956), frustration occurs where a supervening event makes the obligation “radically different” from what was undertaken — a “multi-factorial” inquiry into the terms, context, the parties’ contemplation of risk, the event, and the possibility of future performance.

Construction and Force Majeure

The starting point is the contract’s terms: frustration does not apply where express provision is made, and in practice force majeure and hardship clauses regulate such events. But a force majeure clause covers events resolvable within a relatively short timeframe — in Metropolitan Water Board v Dick Kerr (1918), even a broad delay clause did not prevent frustration when a government order “vitally and fundamentally” changed the contract.

Foreseeability

A foreseeable event generally does not frustrate, the parties being taken to have allocated that risk. In The Eugenia (1964), Lord Denning argued the key question is whether the parties made provision; if they foresaw a danger but did not provide for it, the doctrine could still apply if performance became radically different — though high foreseeability usually implies risk assumption.

Self-Induced Frustration

Frustration must not be due to the party’s own “act or election”. In Maritime National Fish v Ocean Trawlers (1935), it failed because the party chose not to allocate a licence to the contract vessel; in The Super Servant Two (1990), a carrier with an option between two vessels could not claim frustration after one sank, its choice to deploy the other being a human choice.

Frustration of Purpose

  • Krell v Henry (1903): a flat hire was frustrated because viewing the coronation was the foundation of the contract.
  • Herne Bay Steam Boat Co v Hutton (1903): hiring a boat to see a naval review was not frustrated — the review was only the hirer’s motive and the venture his risk.

The Remedial Framework: the 1943 Act

  • Section 1(2): money paid is recoverable and money payable ceases to be payable; the court may allow retention/recovery of expenses where just.
  • Section 1(3): where a party gained a “valuable benefit”, the court awards a “just sum”. In BP v Hunt, Robert Goff J defined “benefit” as the “end product” of services; if a frustrating event destroys it, the benefit may be nil.

Comparison with International Regimes

English law is less liberal than systems like the Principles of European Contract Law, which let courts adapt a contract for “hardship”. English law prefers the certainty of upholding the bargain or terminating it automatically over judicial adjustment.

Recent Force Majeure Instances

The geopolitical and health crises of the 2020s tested force majeure heavily, success often hinging on wording and on the event being the sole cause of non-performance. During the 2026 Middle East energy crisis, Chevron declared force majeure at Israel’s Leviathan gas field after a government order to suspend production on security grounds; QatarEnergy declared force majeure on LNG deliveries after disruption to the Strait of Hormuz; and damage to Qatar’s Ras Laffan terminal illustrated physical impossibility. By contrast, COVID-19 aviation-lease cases (Salam Air, 2020; Wilmington Trust v SpiceJet, 2021) rejected frustration, the lessees having accepted “hell or high water” obligations and the disruption being too short for long leases. And a 2026 Iranian Supreme Court ruling held that long-standing sanctions were a foreseeable risk, defeating a force majeure claim.
