Shirlaw v Southern Foundries (1926) Ltd: HL 1940

Where a party enters into an arrangement which can only take effect by the continuance of an existing state of circumstances, there is an implied engagement on his part that he will do nothing of his own motion to put an end to that state of circumstances.
Lord Atkin said: ‘The arrangement between the parties appears to me to be exactly described by the words of Cockburn C.J. in Stirling v. Maitland (1864) 5 B and S 840, 852: ‘If a party enters into an arrangement which can only take effect by the continuance of an existing state of circumstances’; and in such a state of things the Lord Chief Justice said: ‘I look on the law to be that there is an implied engagement on his part that he shall do nothing of his own motion to put an end to that state of circumstances, under which alone the arrangement can be operative’. That proposition in my opinion is well established law. Personally I should not so much base the law on an implied term, as on a positive rule of the law of contract that conduct of either the promisor or promisee which can be said to amount to himself ‘of his own motion’ bringing about the impossibility of performance is in itself a breach. If A promises to marry B and before performance of that contract marries C, A is not sued for breach of an implied contract not to marry anyone else, but for breach of his contract to marry B.’
