Force Majeure and Impossibility Doctrine

What happens when circumstances make contractual performance impossible, impracticable, or radically different from what the parties contemplated? Force majeure clauses excuse performance when extraordinary events (pandemics, wars, natural disasters) prevent it. The doctrine of impossibility/impracticability provides similar relief even without explicit contractual language when performance becomes objectively impossible or commercially unreasonable. The COVID-19 pandemic stress-tested these doctrines globally, revealing that most force majeure clauses were poorly drafted, many didn't cover pandemics, and courts varied widely in their interpretation. The deeper lesson is about the limits of contractual foresight: no agreement can anticipate every contingency, and the rules for handling unanticipated disruption are among the most consequential in contract law.

When to use it

When drafting or reviewing contracts that need to address catastrophic disruption scenarios. When an extraordinary event has occurred and you need to assess your contractual obligations and options. When building organizational resilience against events that could make normal operations impossible.

How it can help

When drafting any significant contract, spend time on the force majeure clause—it's the section that matters most when things go catastrophically wrong. List specific triggering events rather than relying on general language. Define what 'inability to perform' means and what obligations exist during the force majeure period (notice requirements, mitigation duties, termination rights). After COVID, every serious contract should address pandemic, supply chain disruption, and government shutdowns explicitly.
