Which term describes the concept that something is allowed to continue because all defenses against it are stopped?

The term that describes the concept where something is allowed to continue because all defenses against it are stopped is estoppel. Estoppel is a legal principle that prevents a person from arguing something contrary to a claim they have already made or accepted due to their previous actions or statements. This principle is crucial in ensuring fairness and preventing a party from taking advantage of a situation by asserting defenses after a certain point has been reached or an agreement has been made.

In the context of this question, estoppel operates by preventing a party from retracting their previous positions, thereby allowing the other party to rely on the established understanding or agreement. The application of estoppel can effectively halt any defenses that could be employed against the claims being made, ensuring that the situation continues as if the retracted claim or defense had never existed.
