This article has been written by Subodh Asthana, a second-year student of Hidayatullah National Law University. The author has discussed the doctrine of promissory estoppel.       

Section 2(h) of the Indian Contract Act 1872 states that Contract is an agreement enforceable by law and such agreement means when one person has promised to fulfil one’s obligation to another and when another person backs out or fails to perform one’s obligation to which he has guaranteed then the doctrine of promissory estoppels comes into the picture. To comprehend and study the exact extent of the regulation of promissory estoppels, it is important to follow its inception.

Estoppel is the result of equity principles. It is the recent development in the principles of contracts act where one party has by his words, conduct made to other a promise or assurance which was intended to affect legal relations between the parties. Therefore a person who gives his words cannot be allowed to revert back from what he/she has intended to act.

Promissory Estoppel: Explained

Promissory estoppel is a moderately new advancement. To follow the development of teaching in England, we have to allude to a portion of the English choices. The early cases did not talk about this tenet as estoppel. They discussed it as ‘raising equity’. Lord Cairns expressed the regulation in its most punctual structure in the accompanying words in Hughes v. Metropolitan Railway Company.

“It is the main rule whereupon all courts of equity continue, that if parties who have gone into clear and unmistakable terms which includes certain lawful outcomes for a short time later by their own demonstration or with their own consent enter upon a course of exchange which has the impact of driving one of the parties to assume that the severe rights emerging under the agreement won’t be enforced, or will be kept in anticipation, or held in hold, the individual who generally may have enforced those rights won’t be permitted to uphold them where it would be inequitable having respect to the dealings which have along these lines occurred between the parties.”

The doctrine of Promissory Estoppel was also based on obiter dicta of Justice Denning in Central London Property Trust Ltd vs. High trees House Ltd wherein the court ruled that after promising to reduce the rent of flats and then again increasing it, would affect the intended legal obligations of the parties. It was also held in Combes vs Combes that where one party by his words or conduct made an offer to another party to which any promise and assurance was intended to affect relations between them and to be acted upon accordingly, then one party has taken him on his word and then acted upon it.

Under English Law, the principle and rule has been applied in the case of explicit and not an unequivocal promise where one party, without a new consideration, makes a deal to avoid implementing his rights, since it is inequitable for the promisor to backpedal on such guarantee since the promisee probably adjusted his position independence of the guarantee made, which need not really be inconvenient.

The promisor can resile from his guarantee on giving reasonable notice, which may not be formal, giving the promisee a reasonable chance of continuing his position. The promise would move toward becoming last and irreversible if the promisee can’t continue his position, Promissory estoppel serves to suspend and not entirely quench the current obligation, The rule applies not exclusively to the contractual relationship, yet additionally to statutory rights, or to a connection between neighbouring landowners.

Promissory Estoppel in India

Sometime before the doctrine of promissory estoppel was defined, the Calcutta High Court perceived that the principle of estoppel was not kept distinctly to the law of evidence, however, that an individual might be estopped from doing acts or depending on specific contentions or contention. In a later case, the Bombay High Court empowered the municipality to oppose the case of the Secretary of State to be launched out starting from the earliest stage the municipality had levelled, and raised versatile claims, in the conviction that they had a flat outright which should not be turned out except if other reasonable ground was outfitted, a conviction which was preferable to a desire made by the administrative authority which the legislature realized that the municipality would act upon.

Much later, the Supreme Court connected the standard (with one judge really utilizing the term promissory estoppel) to block the administration from evaluating land income in connection to a market site, when it had prior settled not to charge any lease on business sectors for business sectors would resemble other open buildings.

The court in UOI vs Anglo Afghan Agencies ruled that the doctrine of promissory estoppel discovered its most articulate exposition. For this situation, the writ-applicant had depended on the fare advancement plot issued by the Central Government which had sent out woollen products, and after that guaranteed the import qualification authentication for the full an incentive under the plan. The solicitor put together its case with respect to dependence, and the administration argued official need.

The Supreme Court negatived the protection of official need, and brought up that it didn’t discharge the legislature from its commitment to respect the guarantee made by it, if the native  acting in dependence on the guarantee, had adjusted his position, and that as well, despite that the guarantee was not recorded in the structure required by article 299 of the Constitution.

Afterwards, in Century spinning and manufacturing Co Ltd vs Ulhasnagar Municipality, the doctrine was connected to implement a guarantee of exception from the instalment of octroi obligation given by a metropolitan organisation. The court drew the refinement between the portrayal of the current actuality and description that something would be done in future was spelt out, and it was thus carefully observed.

At last, in, the Supreme Court managed the doctrine of promissory estoppel at the incredible length and held that it afforded a reason for the activity. For this situation in Motilal Padampat Sugar Mills vs. State of UP, wherein the Government of Uttar Pradesh proclaimed a plan exempting all new modern units from deals charge for a long time in the paper. The appealing party sugar organisation got the portrayal affirmed from the Secretary, Industries Department, the Director of Industries, and the Chief Secretary, expressing that in perspective on the business charge exception declared by the administration, is expected to set up a hydrogenation plant for vanaspati.

It was held that the all-out portrayal contained in the letters for the benefit of the Government of Uttar Pradesh, based on which the appealing party acquired cash from money related organizations and set up a plant, conjured the doctrine of promissory estoppel and the administration will undoubtedly complete the portrayal and excluded the litigant from the instalment of offers charge in regard to produced merchandise for a time of three years. 

The Supreme Court has seen that the doctrine of promissory estoppel is a guideline developed by value to keep away from foul play, and however generally named promissory estoppel, it is neither in the domain of agreement nor in the realm of estoppel, yet it is a doctrine advanced by value so as to avert lousy form where guarantee is made by an individual realizing that it would be followed up on by the individual to whom it is made and in actuality it is so followed up on and it is inequitable to permit the gathering making the guarantee to return upon it.

Applicability of Promissory Estoppel in India

On account of Motilal Padampat Sugar Mills the Supreme Court, after a review of Indian, English and American cases, held that:

  • The rule can outfit a reason for the activity.
  • The pertinence of the doctrine isn’t limited to parties as of now authoritatively bound to each other or having a prior legitimate relationship.
  • The doctrine did not depend on estoppel, nor can its task be shackled by consideration. It isn’t essential to demonstrate any consideration for the materialism of the doctrine of promissory estoppel.
  • The rule would be connected where the actualities are with the end goal that foul play can stay away from just by the requirement of guarantee.
  • It is unimportant if no hindrance is appeared to have been caused, it is sufficient if there is a difference in position.
  • The state isn’t resistant from obligation for promissory estoppel and it can’t depend on the doctrine of official need not to shackle its future official activity. It might be connected against the state, even in its legislative or open or sovereign limit, if its application is essential to avert extortion or show unfairness. The official authority is no safeguard.
  • The doctrine of promissory estoppel must respect value when required, yet it isn’t sufficient to state that open intrigue will endure. It will be for the court to choose if the administration indicates reasons.
  • There is no promissory estoppel against the state in its authoritative limit.
  • The certainty that the guarantee isn’t as a formal contract required by workmanship 299 of the Constitution won’t influence the materialism of the doctrine.

Promissory Estoppel in a contractual relationship

The rule of promissory estoppel applies, when it does, just without a finished up contract. It couldn’t be conjured where a particular term in the agreement engaged a bank to end the advance agreement or the organization dropped the permit to run pay phones on expiry of the term or where the court would not expand the mining permit past the concurred time of a half year or wherein regard of office understandings for working pay telephones, rate of commission was decreased and the measure of security store upgraded, and the understanding gave such powers to the phone division.

The rule has been connected to force of the civil law to execute a rent deed, where ensuing upon a correspondence from the load up about distribution, the solicitor had spent sums on getting water and power associations and set up development on the plot or to avoid the power load up from pulling back the refund guaranteed, despite the fact that the standard concurrence with the power shopper explicitly given that the buyers will pay such rates as might be updated by the Board every once in a while.

The rule has been additionally connected to keep town or lodging advancement experts from making changes to plans of portions or to the singular distribution of plots or houses or to force such specialists to allocate or hand over plots or houses or even to keep such specialists from making changes in assignments by amending their policies. It has likewise been connected to implement guarantees of monetary foundations to give fund or advances.

Applicability of doctrine on public and private entities

In the case, the court observed,Public bodies are as much bound as private individual to complete portrayals of certainties and guarantees made by them, depending on which different people have adjusted their situation to their preference, in this way declining to make a refinement between the private individual and a public body as respects the utilization of the doctrine of promissory estoppel. It was recommended that the commitment could emerge as legal action, and if the law requires the agreement to be in a specific structure, it could be authorised in equity.

The case after examining the doctrine of promissory estoppel by and large, chose to what degree the doctrine was pertinent against the administration. The judgment nonetheless, insinuates the utilisation of the doctrine to private gatherings observing.

It is valid that promissory estoppel can’t be summoned to urge the administration or even a private gathering to complete a demonstration denied by law or promissory estoppel can’t be conjured to constrain the legislature or even a private gathering to complete a demonstration restricted by law and keeping in mind that it alludes with endorsement to the perceptions in 41  public bodies or the State is as much bound as private people to complete commitments brought about by them.

In all the Indian cases alluded over, the portrayals comprising the guarantees were made by or for the benefit of the state or public bodies. The doctrine has from there on created in India for the most part in the field of authoritative law.

The primary issue for the situation concerned the applicability of the doctrine to the legislature in its different capacities, and the court continued to choose the equivalent after choosing the extent of the doctrine. There is no case explicitly applying the doctrine between private parties. Except for a lone perception that the rule has been held pertinent to managerial law and not between private parties, there is no perception blocking the utilisation of the rule between private gatherings (not government or public bodies). Nor has the Supreme Court constrained the utilisation of the doctrine while detailing it.

It is along these lines presented that the doctrine as propounded for the situation applies with equivalent power to guarantees and obligations made and created by people other than the legislature or public bodies.

Exceptions to the doctrine

Some immunities and limitations have been given wherein the doctrine of promissory estoppel would not apply. Some of the exceptions of the Doctrine of promissory estoppels are as follows.

  • The doctrine must respect equity when required. The promise may not be upheld against the administration if it is biased to expect the legislature to remember. On the off chance that the administration fights that public intrigue would endure by requirement, the legislature should demonstrate the realities and conditions to the court, and it would be for the court to choose whether those would render it unjust to uphold risk against the government.
  • Mere supplication of the progress of strategy isn’t sufficient, it would need to be legitimised. It is just if the court is fulfilled on appropriate and adequate material set by the administration that superseding and overpowering public intrigue necessitates that the legislature ought not to be held bound by the promise (the weight of indicating it lies on the legislature), the court would decline to authorise it.
  • No portrayal or promise made by an officer can block the legislature from upholding a statutory restriction. The doctrine can’t be profited to allow or excuse a rupture of law. Nor can the legislature or public bodies be constrained to complete the portrayal if it is in opposition to the law, or past their position or power.21 Nor would it be able to be conjured against the activity of administrative authority. The governing body additionally can’t be blocked by this doctrine from practising its capacity.
  • The promisor might be pardoned from playing out the promise in exceptional cases, where the resulting occasions make it outlandish or discriminatory for the promisor to play out his sole obligation.


The portrayal or assurance depended upon must be unambiguous and unequivocal, and not a matter of induction, or a negligible expectation or possibility. But simple demonstrations of extravagance, especially in business exchanges, don’t make rights. While an aim to influence lawful relationship must be set up, such an objective might be found impartially, i.e., it might be demonstrated that the promisor as far as he could tell proposed to influence lawful relationship or that he deliberately so acted that he can’t be heard to state that he didn’t plan this to be the outcome.

At the point when promissory estoppel is conjured, the promise or confirmation essential to help it is definitely not exactly a promising official on the gatherings in the contract. It would not be necessary to summon the doctrine of promissory estoppel at all if the promise held contractual power.

Be that as it may, be the promise supporting promissory estoppel is firmly comparable to in many regards to a promise having a contractual impact. One of its basic properties is a similar level of unequivocally, which with the giving of full thought would have dressed it with contractual effect. In the Court of Appeal, Lord Denning alluded to the exceptional outcomes of holding that an affirmation inadequate (because of inconclusiveness) to shift a contract was yet unmistakable to help promissory estoppel achieving a similar outcome.


To pull in the applicability of the doctrine, it isn’t essential that the promisee, acting in dependence on the promise, ought to have endured any weakness. What is just vital is that the promisee ought to have modified his situation in reliance on the promise, only that he more likely than not been directed to act uniquely in contrast to what he would somehow or another have done.

The altering position should mean such modification in the situation of the promisee as it causes it to appear to the court that holding the promisor to his portrayal is essential to do equity between the parties. The change of position need not include any disadvantage to the promisee except if by drawback, treachery to the promisee, which would result if the promisor was to subside from his promise.

The Law Commission of India couldn’t help contradicting the view that disservice was not necessary, and prescribed that so much hindrance was significant as that harm or misfortune which the promisee was probably going to endure if the promisor was permitted to backpedal on the promise or portrayal.

Promise irrevocable

The promisor may deny his promise except if it is unjust for him to backpedal on it. It would be unfair if the promisee, having acted in dependence on the promise, can’t be re-established to the situation where he was before he made a move. If the promisee can be re-established to that position, the promisor may backpedal on his promise. It has been held that even where there is no abrogating public intrigue, the promisor may resile from the obligation by giving reasonable notice, giving the promisee reasonable open door for continuing his position, if it is feasible for the promisee to reestablish the present state of affairs risk. Be that as it may, if the promisee can’t continue his position, the promise ends up last and irrevocable.


The doctrine depends on dependence, and it produced for anticipating unfairness. Any cure should, in this way, be formed for the reasons for counteracting it.

The promise can be authorised by explicit authorisation, directives and obligations. A fundamental inquiry emerges about the premise of conceding pay rather than the abovementioned when the idea of the exchange requests or when the above cures are insufficient.

When cures in the contract are worried to put the plaintiff in as high a situation as he would have involved had the litigant played out his promise they are said to satisfy the desires caused and to ensure the desire intrigue of the plaintiff. Then again, the assurance of dependence intrigue is worried about putting the plaintiff in as high a situation as he was in before the promise was made, i.e., to put the plaintiff in the status quo. This can be outlined with the accompanying precedents, the principal where the doctrine is utilised as a reason for the activity, and the second where it is utilised as protection.

No Estoppel against Minors

Assume that a minor by distorting his age incites another to contract with him, will there be any estoppels against him, or, as it were, will he be blocked from unveiling his actual age in case coming about because of the contract?

Indeed, even this inquiry had at one time made a debate. Yet, it is currently settled by the dominance of power that there are no such estoppels against a minor.

The infant isn’t ceased from setting up the resistance of outset. The reason is exceptionally straightforward. There can be no estoppel against a resolution. The strategy of the law of contract is to shield people underneath age from contractual risk and usually, the doctrine of estoppels can’t be utilised to overcome that approach. In this manner, for a situation under the steady gaze of the Bombay High Court, Beaumont CJ audited the previous specialists and closed by saying:

“The Court is of the conclusion that where an infant speaks to falsely or generally that he is of age and in this manner incites another into a contract with him then in an activity established on the contract the infant isn’t halted from setting up outset.”


It tends to be said that if the Government of India or of any State in India makes a promise to any individual and the promise isn’t conflicting with the law and regulation that must be adhered to and isn’t against the public intrigue, at that point a short time later it can’t decline to maintain its promise. The Supreme Court of India has said that following up on the affirmation or portrayals are sufficient and ensuing burden, harm or bias caused isn’t to be demonstrated.

It is likewise insignificant whether such portrayal was completely or halfway in charge of such adjustment in the position. It can be also said that wherein the Government or any private entity has promised to fulfil any contractual obligations and then that entity backs out without committing the obligation to its entirety then it would lead to arbitrariness on one party’s right and therefore rights of one party would be lynched if every party is allowed to back from their obligations. Thus the same was also ruled in Pournami Oil Mills Case, wherein the court directed the government to fulfil the promise done by it.
