ABSTRACT
Earl Loreburn: When a lawful contract has been made and there is no default, a court of law has no power to discharge either party from the performance of it unless either the rights of some one else or some Act of Parliament give the necessary jurisdiction. But a court can and ought to examine the contract and the circumstances in which it was made, not of course to vary, but only to explain it, in order to see whether or not from the nature of it the parties must have made their bargain on the footing that a particular thing or state of things would continue to exist. And if they must have done so, then a term to that effect will be implied, though it be not expressed in the contract. In applying this rule it is manifest that such a term can rarely be implied except where the discontinuance is such as to upset altogether the purpose of the contract. Some delay or some change is very common in all human affairs, and it cannot be supposed that any bargain has been made on the tacit condition that such a thing will not happen in any degree.
