A more thorough explanation: Estoppel is a legal doctrine that prevents a person from asserting a claim or right that contradicts or is inconsistent with a previous position, representation, or conduct, especially when such assertion would unfairly harm another party who relied on the original position, representation, or conduct.
Example: The defendant is estopped from denying liability due to the representations made in the contract.
