Explanation:

In contract law, promissory estoppel refers to a theory that when you make a reasonable promise but later you decide to back down, the other party may sue you in order to force you to fulfill your promise.

This theory has been upheld by the Supreme Court in Cohen v. Cowles Media Co. 501 US 663 (1991). So a reasonable promise will have the same binding effect as a contract.
