Impossibility of Performance CASES

In English law, impossibility of performance occurs when contractual obligations become impossible to fulfil due to unforeseen circumstances, potentially excusing parties from further performance.

Definition and Principles

Impossibility can trigger frustration of contract if the impossibility arises without fault from either party and fundamentally changes the nature of contractual obligations.

Common Examples

  • Destruction of the subject matter essential for contractual performance.
  • Performance becoming illegal due to changes in law.
  • Personal services contracts where the individual providing the service becomes incapacitated or dies.

Legal Implications

  • Contracts may be discharged automatically upon impossibility (frustration).
  • Parties typically excused from further performance without liability.

Practical Importance

Understanding impossibility helps manage risks effectively, ensures fair contractual obligations, and clarifies potential relief available when performance becomes genuinely impossible.
