Estoppel is a legal principle that prevents a person from asserting a position inconsistent with their prior conduct if it would result in injustice to another who relied on that conduct. For instance, if one party makes a promise or representation that another party relies upon to their detriment, the first party cannot later contradict that promise or representation. This principle ensures fairness and reliance in legal and business transactions. References: Legal textbooks on contract law, specifically sections on equitable principles and estoppel.
