Definition

A rule of law that prevents a person from asserting something contrary to a position they have previously represented as true, when another person has relied on that representation to their detriment. Section 115 of the Indian Evidence Act, 1872 codifies estoppel. When one person by their declaration, act, or omission intentionally caused another to believe something and act on it, they cannot in proceedings deny the truth of that thing.

Examples

A landlord who accepts rent without objection for years after the lease period expires is estopped from claiming the tenant is a trespasser — the conduct of accepting rent confirms continued tenancy.
A person who represents themselves as the owner of property and induces another to buy it is estopped from later denying their ownership in a suit by the buyer.

Case Study

In Union of India v. Indo-Afghan Agencies (1968), the Supreme Court applied estoppel (and promissory estoppel) against the government — holding that the State cannot approbate and reprobate (blow hot and cold) — a representation made by the government that induced conduct cannot be denied when it would cause injustice to the party who relied on it.
