Central London Property Trust Ltd v. High Trees House Ltd (case)

Central London Property Trust Ltd v. High Trees House Ltd (1947) is a key legal case establishing the concept of promissory estoppel. In this case, a landlord agreed to reduce rent during wartime. Later, they tried to claim the full rent again, but the court held that the landlord couldn't go back on the original promise because the tenant had relied on it. Essentially, the case shows that if someone makes a clear promise that others rely on, they may be prevented from going back on that promise later, even if there was no formal agreement.
