The doctrine of promissory estoppel is an equitable principle developed to prevent injustice. It applies when one party, through clear and unequivocal words or conduct, makes a promise intended to create or affect legal relations, knowing it will be relied upon by the other party. If the promisee acts upon this promise to their detriment, the promisor is bound and cannot retract. Originating from courts of equity in England, estoppel is considered a rule of equity, while in India, it is primarily a rule of evidence. In India, this doctrine applies equally to private individuals and the government. The Law Commission of India, in its 108th Report (1984), proposed the inclusion of Section 25A in the Indian Contract Act, 1872, to address promissory estoppel.

Representation or Promise:
Action in Reliance:
India:
The doctrine was first applied in the 1880 Calcutta High Court case Ganges Mfg. Co. v. Soorujmull. The court held that a promise, even without consideration, could be enforced if acted upon.
England:
The doctrine was introduced by the House of Lords in Thomas Hughes v. Metropolitan Railway Co. (1877). It was later recognized in Central London Properties Ltd. v. High Trees House Ltd. (1947), where Lord Denning established that a promise, if intended and acted upon, is binding.
Promissory estoppel has since evolved and is widely accepted in legal systems worldwide, including India and England.
Under the Indian Contract Act, 1872:
Under Other Indian Laws:
Section 115 of the Indian Evidence Act, 1872:
Article 299 of the Constitution of India:
Motilal Padampat Sugar Mills Co. Ltd. v. State of U.P. (1979):
Union of India v. Indo-Afghan Agencies Ltd. (1968):
Delhi Cloth & General Mills Ltd. v. Union of India (1987):

Pre-existing Legal Relationship:
Reliance and Alteration of Position:
Equity:
Defensive Nature:
Suspensory Effect:
Minors cannot be held liable under promissory estoppel due to the statutory protection they enjoy under contract law. The doctrine cannot override the legal principle that protects minors from contractual liabilities.
Promissory estoppel ensures fairness by preventing a promisor from reneging on promises that have been relied upon to the promisee's detriment. In India, it holds both individuals and government entities accountable, even in the absence of consideration. By promoting equity and justice, the doctrine prevents promissory retraction, ensuring that promises, whether implied or explicit, are legally upheld.
