Termination of Contract in UK Law

So perhaps it would be simpler to say at the outset that frustration occurs whenever the law recognises that without default of either party a contractual obligation has become incapable of being performed because the circumstances in which performance is called for would render it a thing radically different from that which was undertaken by the contract.

Repudiation is a drastic conclusion which should only be held to arise in clear cases of a refusal, in a matter going to the root of the contract, to perform contractual obligations.

If one party so acts or so expresses himself, as to show that he does not mean to accept and discharge the obligations of a contract any further, the other party has an option as to the attitude he may take up. But repudiation by one party standing alone does not terminate the contract: it takes two to end it, by repudiation, on the one side, and acceptance of the repudiation, on the other.

(2) An act of acceptance of a repudiation requires no particular form: a communication does not have to be couched in the language of acceptance. It is sufficient that the communication or conduct clearly and unequivocally conveys to the repudiating party that that aggrieved party is treating the contract as at an end.

I. Frustration of a contract takes place when there supervenes an event (without default of either party and for which the contract makes no sufficient provision) which so significantly changes the nature (not merely the expense or onerousness) of the outstanding contractual rights and /or obligations from what the parties could reasonably have contemplated at the time of its execution that it would be unjust to hold them to the literal sense of its stipulations in the new circumstances; in such case the law declares both parties to be discharged from further performance.

So far as concerns repudiatory conduct, the legal test is simply stated, or, as Lord Wilberforce put it, “perspicuous”. It is whether, looking at all the circumstances objectively, that is from the perspective of a reasonable person in the position of the innocent party, the contract breaker has clearly shown an intention to abandon and altogether refuse to perform the contact.

In my judgment, there is of course a middle ground between acceptance of repudiation and affirmation of the contract, and that is the period when the innocent party is making up his mind what to do. If he does nothing for too long, there may come a time when the law will treat him as having affirmed. If he maintains the contract in being for the moment, while reserving his right to treat it as repudiated if his contract partner persists in his repudiation, then he has not yet elected.
