Estoppel

Estoppel is a judicial device whereby a court may prevent or "estop" a person from making assertions or from going back on their word. The person barred from doing so is said to be "estopped".^[1]^[2] Estoppel may prevent someone from bringing a particular claim. In common law legal systems, the legal doctrine of estoppel is based in both common law and equity.^[3]^[4] Estoppel is also a concept in international law.^[5]
