Estoppel Under the BSA: Sections 121-123 Explained

Estoppel under the BSA, 2023 is the rule of evidence, set out in Sections 121 to 123, that stops a person who has, by declaration, act or omission, led another to believe a fact and act on that belief from later denying the truth of that fact in a proceeding between them. It re-enacts Sections 115 to 117 of the Indian Evidence Act, 1872 in substance, with only renumbering and light modernisation of language. The provisions have applied since the BSA came into force on 1 July 2024. In practice, the doctrine has not changed; what has changed is the section number a lawyer or exam candidate must now cite.

This article sets out what estoppel under the Bharatiya Sakshya Adhiniyam means, the exact Sections 121 to 123 and their Evidence Act equivalents, the essentials, the kinds of estoppel, the leading Supreme Court cases, the exceptions, and how the doctrine compares with res judicata, waiver and admission.

Estoppel is one of those doctrines that sounds technical and turns out to be common sense dressed in Latin. It rests on a simple idea: a person should not be allowed to blow hot and cold, to assert one thing and then its opposite, when someone else has already relied on the first version to their cost.

For law students and judiciary aspirants, the practical worry after 1 July 2024 is smaller than it looks. The estoppel provisions walked across from the old code almost word for word, so the settled case law from decades of Evidence Act practice still governs. You just cite Section 121 where you once cited Section 115.

Estoppel under Section 121 of the Bharatiya Sakshya Adhiniyam, 2023 is a rule of evidence: when a person, by declaration, act or omission, intentionally makes another believe a fact and act on that belief, neither that person nor their representative may later deny its truth in a proceeding between them. It corresponds to Section 115 of the Indian Evidence Act, 1872.

Estoppel under the Bharatiya Sakshya Adhiniyam

Estoppel under the Bharatiya Sakshya Adhiniyam is a rule of evidence that prevents a person from denying, in a legal proceeding, a fact that they earlier caused another person to believe and act upon. The BSA houses it in Chapter VIII, across Section 121 of the Bharatiya Sakshya Adhiniyam, 2023 to Section 123. The word itself comes from the old French estoupail, meaning a stopper or bung, and that is exactly what the doctrine does: it stops a mouth that has already spoken.

Why does this matter in a courtroom? Evidence law is built to help a court find the truth, yet estoppel does something almost opposite. It shuts out evidence of the real facts because the party trying to prove them has, by their own earlier conduct, forfeited the right to be heard on the point. The justification is fairness. A court will not let one person profit from a contradiction that has already trapped another.

The rule and the maxim behind it

The doctrine runs on the maxim allegans contraria non est audiendus: a person alleging contradictory things is not to be heard. English law gave the principle its modern shape in Pickard v. Sears (1837), where the court held that where one person by words or conduct wilfully causes another to believe a certain state of things and induces them to act on that belief, the first person is concluded from averring a different state of things. Indian law absorbed that principle and codified it, first as Section 115 of the Indian Evidence Act, 1872 and now as Section 121 of the BSA.

The rule is narrow but firm. It bites only when a representation has been made, believed, and acted upon. Casual statements that nobody relied on do not create an estoppel, and this is where many pleas collapse.

Why the doctrine exists

The object of estoppel is to prevent fraud and to secure justice between parties by promoting honesty and good faith. It grew out of equity, and equity’s instinct is that a person should not be able to approbate and reprobate, to accept the benefit of a position and then attack it. When a landlord accepts rent on the footing that they own the property, or a seller passes off land as theirs and takes the price, the doctrine steps in to hold them to the version others trusted.

There is a practical edge here too. Commerce depends on people being able to rely on what others tell them. If every representation could be freely retracted the moment it became inconvenient, ordinary dealings would grind to a halt. Estoppel puts a legal cost on going back on your word once someone has acted on it.

A rule of evidence, not a cause of action

Estoppel is a shield, not a sword. It bars a party from denying a fact; it does not, by itself, create a right, a title, or a cause of action. A plaintiff cannot walk into court and sue on estoppel alone. They must have an independent claim, and estoppel then prevents the other side from setting up a particular defence or denial. Courts have repeatedly described estoppel as a rule of evidence, and its placement in an evidence statute, both the old Act and the BSA, confirms that character. For readers who want the older Evidence Act framing in depth, this is well covered in the doctrine’s treatment under the Indian Evidence Act.

A common confusion is whether estoppel can manufacture a title to property that a person never had. It cannot. If the true facts are that a person owns nothing, estoppel may stop the other side from denying a fact in the dispute, but it does not vest ownership by magic. In practice, the doctrine adjusts what each side is allowed to prove; it does not rewrite the substantive law of who owns what.

Sections 121 to 123 of the BSA and their Evidence Act equivalents

Sections 121 to 123 of the Bharatiya Sakshya Adhiniyam, 2023 contain the entire codified law of estoppel, and each maps cleanly onto a provision of the old Indian Evidence Act, 1872. Section 121 carries the general rule from Section 115; Section 122 carries the tenant and licensee estoppel from Section 116; Section 123 carries the acceptor, bailee and licensee estoppel from Section 117. Nothing of substance was dropped or added. The renumbering is the headline, and the doctrine underneath is the same one the courts have applied for a century and a half.

Section 121 BSA, the general rule

Section 121 of the Bharatiya Sakshya Adhiniyam, 2023 states the core principle. In the words of the statute, when one person has, by his declaration, act or omission, intentionally caused or permitted another person to believe a thing to be true and to act upon such belief, neither he nor his representative shall be allowed, in any suit or proceeding between himself and such person or his representative, to deny the truth of that thing.

The section carries a statutory illustration that captures the doctrine perfectly. A intentionally and falsely leads B to believe that certain land belongs to A, and thereby induces B to buy and pay for it. The land afterwards becomes the property of A, and A seeks to set aside the sale on the ground that, at the time of sale, he had no title. He must not be allowed to prove his want of title. That single illustration answers most exam questions on the section, and it is worth memorising in the statutory language.

Section 122 BSA, estoppel of a tenant and of a licensee of a person in possession

Section 122 of the BSA (the successor to Section 116 of the Indian Evidence Act, 1872) prevents a tenant from denying that the landlord had a title to the property at the beginning of the tenancy. A person who came onto the land as a licensee of someone in possession is similarly barred from denying that person’s title at the time the licence was given. The logic is that you cannot take possession under someone, enjoy the property on the footing of their ownership, and then turn around and challenge the very title you accepted.

There is an important limit that examiners love and litigants forget. The estoppel is confined to the state of the title at the beginning of the tenancy. A tenant is not estopped forever. They may show that the landlord’s title has since come to an end, that it has expired, or that a third party has lawfully acquired the title afterwards. In an eviction or possession dispute, this is the difference between a hopeless defence and a viable one: a tenant cannot say “you never owned it”, but they can say “you no longer own it”.

And the rule is a common source of trouble in family and joint-property litigation, where a person let into a house as a licensee later claims to have been a co-owner all along. Section 122 will usually shut down the attempt to deny the possessor’s title at the point the arrangement began.

Section 123 BSA, acceptor of a bill of exchange, bailee or licensee

Section 123 of the BSA (the old Section 117) deals with three commercial actors. An acceptor of a bill of exchange is not permitted to deny that the drawer had authority to draw or to endorse the bill. A bailee or licensee cannot deny that their bailor or licensor had, at the time the bailment or licence began, the authority to make that bailment or grant that licence. Again, the theme is consistency: having dealt with someone on the basis of their authority, you cannot later deny it to escape liability.

The section preserves two explanations that soften the rule at its edges. An acceptor of a bill may still deny that the bill was actually drawn by the person by whom it purports to have been drawn, which keeps the defence of forgery alive. A bailee who delivers the goods back to a person with a better title, or who is compelled to do so, may prove that a third person had a right superior to that of the bailor. These carve-outs stop the estoppel from forcing a party to honour a fraud or to ignore a genuinely superior claim.

What the 1 July 2024 switch changed, and what it did not

The BSA replaced the 152-year-old Indian Evidence Act on 1 July 2024, and for estoppel the change is almost entirely cosmetic. The numbering moved, the drafting was lightly modernised, and the substance stayed put. The decades of precedent built under Sections 115 to 117, including everything the Supreme Court has said about promissory estoppel and its limits, continues to apply to Sections 121 to 123. Early signals from High Court and Supreme Court benches suggest that judgments from mid-2024 onward will simply re-anchor the old authorities to the new numbers, and practitioners expect that re-anchoring to settle within a few years.

For anyone sitting a judiciary or university exam, the safe recall is the mapping itself: Section 121 BSA equals old Section 115, Section 122 equals old Section 116, Section 123 equals old Section 117. A model answer under the new syllabus still follows the same skeleton: define estoppel, state the essentials, give the statutory illustration, note an exception, and cite a leading case. The only adjustment is the section number at the top of the answer. This transition sits inside a much larger renumbering exercise, and it helps to see it alongside how the criminal codes moved too, for example the wider shift from the old codes to the BNSS and BSA, and the way electronic evidence is now treated under Section 63 of the BSA.

Essentials of estoppel under Section 121 BSA

The essentials of estoppel under Section 121 BSA are four, and every one of them must be present before a court will apply the doctrine. Miss one, and the plea fails. The Supreme Court set out and systematised these ingredients in B.L. Sreedhar v. K.M. Munireddy, (2003) 2 SCC 355, which remains the cleanest modern statement of what a party pleading estoppel has to establish.

The four ingredients

The four ingredients can be stated in sequence:

1. A representation. One person makes a representation of an existing fact to another, whether by a positive declaration, by an act, or by an omission or silence where there was a duty to speak.
2. Intention that it be acted upon. The representation is made intentionally, in a way meant to cause the other person to believe it and to act on that belief.
3. Belief and action. The other person genuinely believes the representation and does in fact act on it.
4. Detriment. Acting on the belief, that person alters their position to their prejudice, so that allowing the first person to resile would cause them loss.

The fourth ingredient, detriment, is the one that decides most cases. In Gyarsi Bai v. Dhansukh Lal, AIR 1965 SC 1055, the Supreme Court made clear that estoppel needs a representation, action upon it, and a resulting detriment; where the party claiming estoppel suffered no detriment, the doctrine cannot be invoked. A representation that nobody relied on, or reliance that cost nothing, will not raise an estoppel however clear the words were.

One more point of substance: estoppel operates on representations of fact, not on promises about the future. A statement about what presently exists can found an ordinary estoppel under Section 121. A promise about what one will do later belongs to the separate doctrine of promissory estoppel, which is treated below.

Who can plead estoppel, and the burden of proof

Only the person to whom the representation was made, or their representative in interest, can set up the estoppel. It is a personal and, in a sense, mutual bar: it binds the maker of the representation in favour of the person who was misled, and not the world at large. A stranger who happened to overhear the representation but never acted on it gains nothing from it.

The burden of proving an estoppel lies squarely on the party who asserts it, and the plea must be raised specifically. Estoppel is not something a court is expected to discover on its own from a general narrative. It has to be pleaded with the representation, the reliance, and the detriment set out, and then proved. Where the real facts are equally known to both sides, there is no estoppel at all, because a person cannot say they were misled about something they knew as well as the maker.

Kinds of estoppel

Estoppel takes several forms that Indian courts have recognised over time, and knowing the taxonomy helps a reader place any given fact situation in the right box. The forms overlap at the edges, but each has a distinct trigger. Is every one of them found in the BSA? No. The statute codifies estoppel by conduct and the specific tenancy and commercial estoppels; the other varieties are judicial and equitable developments that sit alongside the code.

Estoppel by record, by deed, and by conduct

Estoppel by record arises from the decision of a competent court: once a matter has been finally decided, the parties are bound by that record and cannot reopen it. In Indian practice this shades into res judicata, discussed later. Estoppel by deed prevents a party to a formal deed from denying facts that the deed recites, though its role in Indian law is limited compared with English conveyancing.

Estoppel by conduct, also called estoppel in pais, is the everyday form and the one Section 121 codifies. It arises from a representation by declaration, act or omission outside any deed or record, and it covers the great mass of estoppel disputes, from land sales to commercial dealings.

Promissory estoppel and equitable estoppel

Promissory estoppel is the equitable offshoot that deals with promises about future conduct rather than statements of existing fact. Where a person makes a clear and unequivocal promise intended to create legal relations, and the other party acts on it, the promisor may be held to the promise even without consideration. Its modern origin lies in the English decision in Central London Property Trust Ltd. v. High Trees House Ltd. (1947), and Indian courts developed it vigorously against the Government, as the next section shows. “Equitable estoppel” is simply the broader label for these equity-based estoppels, which include promissory estoppel and, in property contexts, proprietary estoppel.

Estoppel by acquiescence and estoppel by negligence

Estoppel by acquiescence arises where a person stands by in silence while another acts on a mistaken belief, when they had a duty and an opportunity to speak. Their silence becomes a representation, and they are later barred from asserting the right they sat on. Estoppel by negligence arises where a person owes a duty of care, breaches it, and by that breach enables a third party to be misled, for instance by carelessly allowing another to appear as the owner of goods.

Issue estoppel and estoppel in criminal proceedings

Issue estoppel prevents a particular issue of fact, once finally decided between the same parties by a competent court, from being reopened in later proceedings between them. It is distinct from the general bar on double jeopardy or autrefois acquit, which concern being tried twice for the same offence. Indian courts accept that issue estoppel operates in criminal law: if a fact essential to the prosecution has been decided in the accused’s favour in an earlier trial, the prosecution cannot ask a later court to find the opposite. That is a narrow but real application, and it links to the broader use of inherent powers and issue estoppel in criminal matters. Outside that limited space, there is generally no estoppel in criminal law to legalise an offence, a point taken up under exceptions.

Promissory estoppel and estoppel against the Government

Can promissory estoppel bind the Government? Yes, and this is the most litigated and most exam-relevant corner of the whole doctrine. Where a public authority makes a clear and unequivocal promise, intending it to be acted upon, and a citizen or business does act on it to their prejudice, the authority can be held to that promise even in the absence of a formal contract. The Indian courts built this rule over roughly four decades, and it remains good law under the BSA because the doctrine is judicial and equitable, not tied to any section number that changed in 2024.

How the doctrine reached the State

The turning point came in Union of India v. Indo-Afghan Agencies Ltd., AIR 1968 SC 718, where exporters of woollen goods acted on an Export Promotion Scheme assurance of import entitlements and then received less than promised. The Supreme Court held the Government bound by its representation despite the absence of a formal contract executed under Article 299 of the Constitution. A few years later, in Century Spinning & Manufacturing Co. Ltd. v. Ulhasnagar Municipal Council, (1970) 1 SCC 582, the Court confirmed that a public body is not free to ignore a representation that a citizen has relied upon to their detriment, and that it can be held to its word like any other party.

This was a genuine shift. For a long time the assumption had been that the State, acting in the public interest, could change course freely. These decisions established that reliance has consequences even when the party on the other side wears the coat of government.

The high-water mark

The doctrine reached its fullest expression in Motilal Padampat Sugar Mills Co. (P) Ltd. v. State of Uttar Pradesh, (1979) 2 SCC 409, where a sugar manufacturer set up a new unit relying on a State announcement of a total sales-tax exemption for new units, only for the State to resile. The Supreme Court held that a clear and unequivocal promise, intended to be acted upon and in fact acted upon, binds the Government, and that the burden of showing any overriding equity to escape the promise lay on the State. The Court also clarified that waiver, if relied on, must be pleaded and proved, and it drew the line between estoppel on an existing fact and promissory estoppel on a future promise.

In practice, this is the case every judiciary aspirant should be able to state in two sentences, because it anchors the entire government-promise line of authority. It is also the case counsel reach for first whenever an incentive or exemption is withdrawn after industry has committed capital in reliance on it.

Modern reaffirmation and its boundary

The Supreme Court reaffirmed the principle in State of Punjab v. Nestle India Ltd., (2004) 6 SCC 465, holding the State to an assurance on purchase tax that a manufacturer had acted upon, while distinguishing a legitimate change of policy from a broken promise. The consistent thread is that a clear promise plus detrimental reliance binds the State, but the doctrine is not a blank cheque. Where the promise runs into a statute, or genuine public interest demands a change, the equity yields. Those boundaries are the subject of the next section.

Exceptions and limitations of estoppel

Estoppel does not apply in several important situations, and these exceptions are where strong-looking claims most often die. The doctrine is equitable and subordinate to the law: it cannot be used to defeat a statute, to bind those the law protects, or to freeze the State’s essential functions. Any answer or argument on estoppel is incomplete without them.

No estoppel against a statute or the law

There is no estoppel against a statute. A person cannot, by representation or conduct, confer on a court a jurisdiction that the law withholds, validate something the law declares void, or compel an authority to act contrary to a mandatory provision. The same principle means there is generally no estoppel in criminal proceedings to legalise an offence: parties cannot agree or represent their way out of what the criminal law forbids.

The point recurs in tax and incentive litigation. In M/s Sharma Transport v. Government of Andhra Pradesh, (2002) 2 SCC 188, the Supreme Court accepted that promissory estoppel is well established in administrative law but confirmed that it is subject to limits, and that an exemption notification can be withdrawn without offending the doctrine. In Kasinka Trading v. Union of India, (1995) 1 SCC 274, the Court held that an exemption granted in public interest can equally be withdrawn in public interest, and that promissory estoppel yields to an overriding public interest and to the requirements of statute. Estoppel cannot chain the legislature or an authority exercising statutory power.

No estoppel against a minor

A minor cannot be estopped in a way that defeats the protection the law gives them. The classic authority is Mohori Bibee v. Dharmodas Ghose (1903), where the Privy Council held a minor’s agreement to be void, and it is settled that a minor who misrepresents their age to obtain a loan or enter a contract is not estopped from later pleading minority. To hold otherwise would let estoppel undo the statutory incapacity that exists precisely to shield minors. This is a favourite illustration of how estoppel bows to a protective rule of substantive law.

No estoppel against sovereign and legislative functions

Estoppel does not operate to fetter the State in the exercise of its sovereign, legislative, or essential executive functions. A government cannot be estopped from performing a public duty or from making policy that the public interest requires, even if an earlier assurance pointed the other way. In Delhi Cloth & General Mills Ltd. v. Union of India, (1988) 1 SCC 86, the Supreme Court underlined that promissory estoppel needs a clear and unambiguous promise that the other party has acted on by altering its position, and that it cannot compel the Government to act beyond its power or contrary to law; a provisional or contingent representation creates no binding promise at all.

This is the second-order consequence that keeps government-promise litigation alive year after year. Every time an industrial policy, subsidy, or tax concession is withdrawn, the same tension replays: industry pleads reliance, and the State pleads statute and public interest. Practitioners who can map a client’s facts onto the right side of that line, promise-and-reliance versus statute-and-policy, are the ones who win these cases, and the demand for that skill is not going away.

No estoppel on a point of law, or where both parties know the truth

Estoppel is about facts, not law. There is no estoppel on a pure question of law, so parties cannot, by agreeing on the legal position, bind a court to a wrong view of the law. Equally, there is no estoppel where the true facts are known to both sides, because a person cannot claim to have been misled about something they knew as well as the other. These two limits together stop the doctrine from being used as a device to manufacture legal results that the facts and the law do not support.

Estoppel compared: res judicata, waiver, admission and promissory estoppel

Estoppel is often confused with three neighbouring concepts, and the comparisons are a reliable source of exam questions and pleading errors alike. Each shares a family resemblance with estoppel but differs in source, effect, and who can raise it. Getting the distinctions right is what separates a confident answer from a muddled one.

Estoppel versus res judicata

Estoppel is a rule of evidence that stops a party from denying a fact they represented; res judicata, under Section 11 of the Code of Civil Procedure, 1908, is a bar that stops a matter already decided between the same parties from being litigated again. Estoppel flows from the conduct of a party, while res judicata flows from the decision of a court. Estoppel binds only the party who made the representation, whereas res judicata binds both parties equally and goes to the jurisdiction of the court to try the matter afresh. One is about what you may prove; the other is about whether you may litigate at all.

Estoppel versus waiver

Waiver is the intentional relinquishment of a known right, while estoppel arises from misleading another into a belief they act upon. Waiver depends on the conduct of the party giving up the right and needs no detriment to the other side; estoppel depends on the effect of a representation on the person who relied on it and requires that reliance to have caused detriment. A right can be waived deliberately with full knowledge; an estoppel can arise even where the maker did not intend to surrender any right, so long as the representation misled the other party.

Estoppel versus admission

An admission is a statement, oral or documentary, that suggests an inference about a fact in issue; it is a piece of evidence and, as a rule, it can be explained or rebutted. Estoppel is stronger: it is a conclusive bar that shuts out the truth altogether on the point covered. Put simply, an admission may be shown to be mistaken, but an estoppel does not allow the party bound by it to prove that the represented fact was false. The two often arise from the same words, yet their legal force is very different.

Estoppel versus promissory estoppel

Ordinary estoppel under Section 121 rests on a representation of an existing fact; promissory estoppel rests on a promise about future conduct. The first is a rule of evidence codified in the BSA; the second is an equitable doctrine developed by the courts and applied notably against the Government. And promissory estoppel can, in a limited way, be enforced even without consideration, which is why it is sometimes discussed alongside the Indian Contract Act, 1872 rather than the evidence code. A related question, whether estoppel and limitation are the same, has a short answer: they are not. Limitation bars a remedy after a fixed period regardless of any representation, while estoppel bars a denial regardless of time.

Frequently asked questions

1. What is estoppel under the Bharatiya Sakshya Adhiniyam? Estoppel under the Bharatiya Sakshya Adhiniyam, 2023 is a rule of evidence in Sections 121 to 123 that stops a person from denying a fact they earlier caused another to believe and act upon. It re-enacts the estoppel provisions of the Indian Evidence Act, 1872 and has applied since 1 July 2024. The doctrine prevents a party from taking contradictory positions to another’s prejudice.

2. Which section of the BSA deals with estoppel? Section 121 of the BSA lays down the general rule of estoppel, and Sections 122 and 123 deal with specific estoppels of tenants, licensees, acceptors of bills of exchange and bailees. Together, Sections 121 to 123 in Chapter VIII contain the entire codified law of estoppel. They correspond to Sections 115 to 117 of the old Indian Evidence Act.

3. What is Section 121 of the BSA? Section 121 is the general estoppel provision. It says that when a person, by declaration, act or omission, intentionally makes another believe a thing to be true and act on that belief, that person cannot later deny its truth in a proceeding between them. It is the direct successor to Section 115 of the Indian Evidence Act, 1872.

4. What is the doctrine of estoppel in simple words? In simple words, estoppel means you cannot go back on what you led someone else to believe if they relied on it and would be harmed. If your words or conduct made another person act to their cost, the law stops you from denying what you represented. It exists to prevent fraud and to keep people to positions others have trusted.

5. Give an example of estoppel under Section 121 BSA. The statute’s own illustration is the standard example. A falsely leads B to believe that certain land belongs to A, and B buys and pays for it; the land later actually becomes A’s, and A tries to cancel the sale by saying he had no title when he sold. The law does not allow A to prove his want of title, so the sale stands.

6. What is the Indian Evidence Act equivalent of Section 121 BSA? Section 121 of the BSA corresponds to Section 115 of the Indian Evidence Act, 1872. Section 122 corresponds to Section 116, and Section 123 corresponds to Section 117. The provisions were carried over in substance, so precedent under the old sections still applies.

7. Did the BSA change the law of estoppel? No, not in substance. The BSA renumbered the estoppel provisions and lightly modernised the language, but the rule, its essentials, and the case law remain the same. A lawyer now cites Section 121 where they once cited Section 115, and the settled Supreme Court authority continues to govern.

8. What are the essentials of estoppel? There are four: a representation of an existing fact; made with the intention that it be acted upon; belief in and action on that representation by the other party; and detriment suffered because of that reliance. All four must be present. The absence of detriment, in particular, defeats the plea.

9. On whom does the burden of proving estoppel lie? The burden lies on the party who sets up the estoppel, and it must be specifically pleaded. A court will not infer estoppel from a general narrative; the representation, the reliance, and the detriment have to be pleaded and proved. Where both parties knew the true facts, no estoppel arises.

10. How many kinds of estoppel are recognised in Indian law? Indian law recognises several kinds, including estoppel by record, estoppel by deed, estoppel by conduct (in pais), promissory estoppel, estoppel by acquiescence, estoppel by negligence, and issue estoppel. Section 121 of the BSA codifies estoppel by conduct, while the others are largely judicial and equitable developments. They overlap at the edges but each has a distinct trigger.

11. What is promissory estoppel? Promissory estoppel is an equitable doctrine under which a clear and unequivocal promise about future conduct, intended to be acted upon and in fact acted upon, can bind the promisor even without consideration. Indian courts have applied it notably to hold the Government to its assurances. It differs from ordinary estoppel, which rests on a representation of existing fact.

12. Can promissory estoppel be invoked against the Government? Yes. Where the Government makes a clear and unequivocal promise, intending it to be acted upon, and a party acts on it to their detriment, the Government can be held to the promise even without a formal contract. This was established in a line of Supreme Court cases from the late 1960s onwards. The doctrine is subject to limits where a statute or genuine public interest intervenes.

13. What is the difference between estoppel and res judicata? Estoppel is a rule of evidence that bars a party from denying a represented fact; res judicata, under Section 11 of the Code of Civil Procedure, 1908, bars re-litigation of a matter already decided. Estoppel arises from a party’s conduct and binds only the maker of the representation. Res judicata arises from a court’s decision and binds both parties.

14. What is the difference between estoppel and waiver? Waiver is the intentional giving up of a known right and needs no detriment to the other side. Estoppel arises from misleading another into a belief they act upon, and it requires that reliance to have caused detriment. Waiver looks at the conduct of the person surrendering the right; estoppel looks at the effect on the person misled.

15. Can estoppel be used against a minor or against a statute? No to both. A minor who misrepresents their age is not estopped from pleading minority, because estoppel cannot defeat the protection the law gives minors. Likewise, there is no estoppel against a statute: no representation or conduct can validate what the law forbids or confer a jurisdiction the law withholds.

16. Does estoppel apply in criminal proceedings? Only in a limited way. Issue estoppel can prevent the prosecution from reopening a fact already decided in the accused’s favour between the same parties, which is distinct from the bar on double jeopardy. Beyond that, there is generally no estoppel in criminal law to legalise an offence or to oust the court’s jurisdiction.
