A Legal Article on the Doctrine of Promissory Estoppel in Indian Administrative Law
Author : Aanjaney Maratha, Student at Jindal Global Law School, O.P Jindal Global University
Abstract
This article examines promissory estoppel as applied against the Indian State and asks how the doctrine reconciles judicial equity with the constitutional separation between executive policy and judicial enforcement. Beginning with the foundational case of Motilal Padampat Sugar Mills, the article traces the doctrine’s expansion to cover non-contractual governmental assurances, its recognized exceptions for illegality and public interest, and its most recent restatement in State of Himachal Pradesh v. M/s Kundlas Loh Udyog (2026). The article argues that Indian courts have kept the doctrine within workable bounds chiefly through one discipline: estoppel can hold government to a promise it made but cannot extend a promise to cover ground it never intended to cover. The article situates this discipline within the wider debate on whether judicially evolved equity encroaches on legislative and executive policy space and closes with practical takeaways for parties seeking to rely on governmental assurances.
To the Point
A government department promises a tax holiday to attract investment. A company spends crores acting on that promise. Years later, the department changes its mind. Can the company hold the government to its word? Indian courts have answered this question for nearly fifty years through the doctrine of promissory estoppel, and in May 2026, the Supreme Court added another important chapter in State of Himachal Pradesh v. M/s Kundlas Loh Udyog. The doctrine lets a promise enforce a promise even without a contract or consideration, but only within strict limits. It cannot rewrite a policy, compel illegality, or override the public interest. This piece traces that boundary, explains why it matters for businesses dealing with the State, and looks at where the doctrine may be headed next.
Use of Legal Jargon
Estoppel, in ordinary contract law, stops a person from denying something they earlier represented as true. Promissory estoppel extends this idea to future promises rather than statements of existing fact. It is distinct from estoppel under Section 115 of the Indian Evidence Act, 1872, which governs representations of fact, not promises of future conduct. The doctrine operates independently of consideration, the requirement under Section 10 of the Indian Contract Act, 1872 that every enforceable promise be supported by something given in return. It also bypasses, in practical effect, the formal contracting requirements of Article 299 of the Constitution, which insists that government contracts be executed in the name of the President or Governor and in writing.
Two doctrines often travel together in this area and are worth distinguishing. Promissory estoppel concerns private reliance on a promise. Legitimate expectation, by contrast, concerns a procedural or substantive expectation arising from a settled practice or representation, and is reviewed under administrative law principles of fairness and non-arbitrariness rather than contractual reliance. Courts also speak of the doctrine being subject to the “executive necessity” exception and the “public interest” override, both shorthand for situations where the State is permitted to resile from its promise.
The Proof
The doctrinal foundation lies in Motilal Padampat Sugar Mills v. State of U.P., where Justice Bhagwati held the government bound by its assurance of sales tax exemption even though no formal contract existed and no consideration had passed. The Court’s reasoning rested on equity: a clear and unequivocal promise, intended to be acted upon, that was in fact acted upon, would bind the promisor unless inequity could be avoided some other way.
This was not the first appearance of the idea against the State. In Union of India v. Indo-Afghan Agencies Ltd., the Supreme Court had already enforced assurances made under an export incentive scheme, holding that the absence of a formal contract did not defeat the claim. Earlier still, Collector of Bombay v. Municipal Corporation of the City of Bombay restrained the government from making a fresh demand for land revenue after the Corporation had altered its position on the strength of an official assurance.
The limits emerged just as clearly through later cases. Jit Ram Shiv Kumar v. State of Haryana briefly suggested that the doctrine could not apply to the exercise of executive functions, a doubt the Court resolved in Union of India v. Godfrey Philips India Ltd. by affirming Motilal Padampat as the correct statement of law. Kasinka Trading v. Union of India and Shree Sidhbali Steels Ltd. v. State of U.P. confirmed that fiscal and economic policy can be altered in the public interest notwithstanding an earlier promise, provided the change is bona fide and not arbitrary. State of Rajasthan v. Mahaveer Oil Industries and Shrijee Sales Corporation v. Union of India applied the same reasoning to withdrawal of import and customs concessions.
The most recent application of this proof comes from State of Himachal Pradesh & Ors. v. M/s Kundlas Loh Udyog (2026 INSC 534), decided on 25 May 2026 by Justices J.B. Pardiwala and K.V. Viswanathan. The Himachal Pradesh Industrial Policy, 2019 offered concessional electricity tariffs to “eligible enterprises” under Clause 16(a), while Clause 16(b) gave existing units undertaking expansion a separate rebate. The respondent company, an existing unit that had expanded its operations, claimed the Clause 16(a) tariff benefit as an “eligible enterprise.” The High Court agreed on a literal reading of the words. The Supreme Court reversed, holding that the clause, read in the context of the policy’s structure, was meant only for genuinely new industrial units, and that allowing the respondent’s claim would hand it a double benefit never intended by the policy. A later amendment substituting “new” for “eligible” was treated as clarificatory of the original intent rather than a fresh change in the law. The Court’s central holding bears directly on this article’s theme: promissory estoppel can compel the State to honor a promise it made but cannot be used to manufacture an entitlement the promise never covered.
Case Laws
- Motilal Padampat Sugar Mills Co. Ltd. v. State of Uttar Pradesh, (1979) 2 SCC 409 — Established that the government can be bound by a clear promise even absent consideration or a formal contract, where the promisee has acted upon it.
- Union of India v. Indo-Afghan Agencies Ltd., (1968) SCR (2) 366 — Applied the doctrine to enforce assurances made under an export incentive scheme without a pre-existing contractual relationship.
- Collector of Bombay v. Municipal Corporation of the City of Bombay, (1952) SCR 43 — An early instance restraining the government from resiling from an assurance after the other party altered its position.
- Jit Ram Shiv Kumar v. State of Haryana, (1980) 3 SCR 689 — Held, controversially, that the doctrine could not apply to executive functions of the State; later disapproved.
- Union of India v. Godfrey Philips India Ltd., (1985) 4 SCC 369 — Disapproved Jit Ram and reaffirmed Motilal Padampat as the governing law on promissory estoppel against the State.
- Kasinka Trading v. Union of India, (1995) 1 SCC 274 — Recognized that the doctrine yields to a bona fide change in fiscal or economic policy made in the public interest.
- Shree Sidhbali Steels Ltd. v. State of U.P., (2011) 3 SCC 193 — Confirmed that industrial and fiscal concessions remain subject to modification or withdrawal for public interest reasons.
- State of Rajasthan v. J.K. Udaipur Udyog Ltd., (2004) 7 SCC 673 — Held that beneficiaries of policy concessions do not acquire indefeasible rights, since such concessions remain defeasible.
- State of Himachal Pradesh & Ors. v. M/s Kundlas Loh Udyog, 2026 INSC 534 — Held that promissory estoppel cannot be invoked to claim a benefit that a government policy never intended for the claimant’s category, even where the claimant relied on the policy and altered its position.
Conclusion
Fifty years after Motilal Padampat, promissory estoppel against the State has settled into a doctrine with a clear, if narrow, channel. It binds government to promises it made and intended to be relied upon. It does not bind government to promises imagined from ambiguous wording, nor does it freeze fiscal and economic policy against bona fide change in the public interest. Kundlas Loh Udyog reaffirms this channel rather than departing from it: the Court did not weaken estoppel against the State; it simply declined to stretch a specific clause beyond the category of beneficiaries it was written for. Read together with the public interest exception recognized since Kasinka Trading, the doctrine today functions less as a judicial override of legislative or executive intent and more as a check against government acting inconsistently with intent it has itself clearly expressed. The encroachment debate that animated early academic criticism has, in this sense, been answered by judicial self-discipline rather than legislative correction. For businesses dealing with the State, the lesson of the 2026 ruling is practical: reliance on a policy is only as strong as the promise the policy contains.
FAQs
Q1. Can promissory estoppel be used against the legislature when making a law?
No. The doctrine restrains executive and administrative conduct; it cannot compel the legislature to enact, retain, or refrain from amending a statute.
Q2. Does a party need to show financial loss to claim promissory estoppel?
No. Indian courts have held that what matters is a change of position in reliance on the promise, not proof of monetary detriment.
Q3. Can the government ever go back on a promise it made?
Yes, where withdrawing the promise is necessary to prevent harm to the public interest or where honouring it would require the State to act unlawfully or beyond its powers.
Q4. What did the 2026 Kundlas Loh Udyog case decide?
It held that a company could not claim a tariff benefit meant only for new industrial units, since the policy clause in question was never intended to cover existing units that had merely expanded, regardless of reliance.
Q5. Is promissory estoppel the same as legitimate expectation?
No. Promissory estoppel arises from a specific promise relied upon by a party; legitimate expectation arises from a consistent past practice or representation and is assessed under administrative law fairness standards, independent of individual reliance.
