Having set express termination clauses (ETCs) in their legal context, this article's first aim is briefly to explain three significant points concerning their operation which have now been clarified. Other important questions remain unresolved, and the second aim is to explore four of them: the judicial “reading down” of ETCs; whether termination need be immediate; the recoverability of expectation damages; and the avoidance of an unintended repudiation. Respects in which the English law of contract on each of them would benefit from development or change are identified, and it is argued that the Canadian approach to the award of expectation damages following termination pursuant to an ETC is preferable to the established Anglo-Australian position.
