Frustration

Frustration discharges a contract when a supervening event, through no fault of either party, renders performance radically different from what was undertaken (Davis Contractors Ltd v Fareham UDC [1956]). The test is objective: would performance in the new circumstances be fundamentally different from the original obligation? The doctrine operates as a rule of law imposed when justice requires discharge, not as an implied term. It is deliberately narrow—mere difficulty, expense, or delay does not suffice. The rationale balances competing imperatives: while contracts should be kept (pacta sunt servanda), holding parties to obligations transformed beyond recognition would be unjust. Courts expect sophisticated parties to allocate risks expressly through force majeure clauses; frustration remains a residual doctrine of last resort.

Taylor v Caldwell (1863) 3 B & S 826: Destruction of subject matter discharges the contract; a music hall burning down frustrated the hire contract. This foundational case established that absolute contracts yield to impossibility.

Davis Contractors Ltd v Fareham UDC [1956] AC 696: Lord Radcliffe reformulated the test—frustration occurs when performance becomes 'radically different'. Mere increased cost and delay from labour shortages did not frustrate a building contract. This remains the leading modern authority.

Krell v Henry [1903] 2 KB 740: Cancellation of Edward VII's coronation frustrated a contract to hire rooms overlooking the procession route. The case establishes frustration of purpose where the common foundation fails, though compare Herne Bay v Hutton where partial purpose remained.

Maritime National Fish Ltd v Ocean Trawlers Ltd [1935] AC 524: Self-induced frustration precludes the doctrine; choosing to allocate fishing licences elsewhere prevented reliance on frustration. A party cannot engineer their own escape.

The Sea Angel [2007] EWCA Civ 547: Modern synthesis requiring multi-factorial assessment: contractual terms, parties' knowledge, nature of supervening event, risk allocation. The inquiry remains fact-sensitive within the 'radically different' framework.

Courts follow a structured analysis. First, identify the supervening event and confirm it arose without fault of either party. Second, construe the contract to understand what was originally undertaken. Third, assess whether performance in the new circumstances would be radically different—not merely harder or less profitable. Key factual triggers include: destruction of subject matter (Taylor v Caldwell); supervening illegality through war or statute; death/incapacity in personal service contracts; destruction of the common purpose known to both parties (Krell v Henry). Courts examine whether parties foresaw the risk or allocated it contractually—force majeure clauses typically exclude frustration. The Law Reform (Frustrated Contracts) Act 1943 then governs financial adjustments: recovery of money paid (s.1(2)), retention for expenses, and payment for valuable benefits (s.1(3)).

Students routinely conflate frustration with mistake (which concerns pre-existing facts at formation) or breach (which involves fault). The biggest error is finding frustration too readily—remember Tsakiroglou where doubling voyage cost via Cape route didn't frustrate. Always check for express risk allocation in force majeure clauses. Don't overlook foreseeability (Amalgamated Investment)—if parties could anticipate the event, frustration unlikely applies. Self-induced frustration (Maritime National Fish) bars the doctrine entirely. Remember leases rarely frustrate (National Carriers). Always address the 1943 Act's financial consequences after establishing frustration—omitting statutory analysis loses marks.
