Burden of Proof, Presumptions and Estoppel under the Bharatiya Sakshya Adhiniyam, 2023
Sections 104 to 123 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA) answer one of the most important questions in litigation: who must prove what? The chapter moves from the general burden of proof to special burdens, facts especially within knowledge, statutory presumptions, presumptions concerning marriage, suicide, dowry death and consent, and finally estoppel.
The subject is especially important in criminal cases because a special evidentiary burden must never be confused with the prosecution’s foundational duty to prove the offence. This article should be read with our BSA foundation guide, BNS General Exceptions guide, and our specialist articles on admissions and confessions and electronic evidence.
- Section 104 states the general rule: a person asking the court to give judgment based on asserted facts must prove those facts.
- Section 105 asks who would fail if no evidence were given by either side; that person carries the burden.
- Section 108 places the burden on an accused who invokes a BNS General Exception or a special exception/proviso, while the court presumes the absence of those circumstances unless established.
- Section 109 concerns facts especially within a person’s knowledge, but it does not relieve the prosecution of its initial burden in a criminal case.
- In Ravi v. State of Punjab, 2025 INSC 170, the Supreme Court reaffirmed that the special-knowledge rule cannot be used to cure a prosecution case that has not first established the circumstances pointing to guilt.
- Section 116 creates a rule of conclusive proof concerning legitimacy of a child born during a valid marriage or within the statutory post-dissolution period, subject to the no-access exception.
- Section 117 uses the expression may presume for abetment of suicide by a married woman where statutory conditions are met.
- Section 118 uses shall presume for dowry death once the statutory foundational facts are established.
- Section 119 permits the court to presume facts from the common course of natural events, human conduct and business; its illustrations include adverse inference for withholding evidence.
- Section 120 creates a statutory presumption of absence of consent in the specified rape prosecution once the statutory preconditions are established and the woman states that she did not consent.
- Sections 121–123 codify estoppel. Estoppel controls what a party may deny after inducing another to act on a representation; it does not generally create substantive rights contrary to law.

Official Statutory Framework
Chapter VII of the BSA is titled Of the Burden of Proof and runs from Sections 104 to 120. Chapter VIII, Estoppel, contains Sections 121 to 123. The official statute is available on India Code.
For examination purposes, the chapter should not be memorised as twenty disconnected provisions. It follows a logical progression: general burden → special burden → presumptions → estoppel.
Part I — Burden of Proof and Evidential Onus
Burden of Proof vs Onus of Proof
The expressions are often used interchangeably in ordinary argument, but a useful doctrinal distinction exists. The legal burden identifies which party ultimately has to establish a proposition required for judgment. The evidential onus describes the practical obligation to answer evidence once the opposing side has produced material sufficient to call for an explanation.
| Point | Legal Burden | Evidential Onus |
|---|---|---|
| Nature | Ultimate obligation to establish a required proposition | Practical need to answer evidence or establish a particular fact |
| Movement | Often fixed by substantive/evidence law | May shift during the trial as evidence develops |
| Criminal example | Prosecution must prove offence ingredients | Accused may need to explain a fact especially within knowledge after foundational prosecution facts are shown |
| Risk of error | Failure may determine the case | Failure may permit an inference only where law and proved facts justify it |
Part II — Sections 104–107: General Burden Rules
Section 104: The Foundational Rule
Section 104 provides the starting proposition. Whoever desires a court to give judgment as to a legal right or liability dependent on the existence of facts asserted by that person must prove that those facts exist. When a person is bound to prove a fact, the burden of proof is said to lie on that person.
In a civil action, the plaintiff ordinarily carries the burden on facts constituting the cause of action, while the defendant carries the burden on affirmative defences requiring separate facts. In a criminal prosecution, the State ordinarily bears the burden of proving the factual and mental ingredients of the offence.
Section 105: Who Would Fail if Nobody Led Evidence?
Section 105 gives a practical test: the burden lies on the person who would fail if no evidence at all were given on either side. This hypothetical is especially useful in civil disputes.
Section 106: Burden as to a Particular Fact
Section 106 separates the burden relating to a particular fact from the ultimate burden on the whole case. The person who wants the court to believe a particular fact ordinarily has to prove it unless another law places that burden elsewhere.
This is why an accused who asserts a specific alibi, a civil party who asserts payment after admitting the debt, or a litigant who alleges a special waiver may carry the burden concerning that particular factual proposition even though another party carries the ultimate burden on the main dispute.
Section 107: Foundational Facts for Admissibility
Sometimes one fact must be proved before another item of evidence can become admissible. Section 107 places the burden of proving that foundational fact on the person who wishes to rely on the dependent evidence.
Before relying on a statement under the unavailable-maker rule, prove the statutory circumstance that makes the maker unavailable and the relevant Section 26 category.
Before tendering a copy under the secondary-evidence route, prove the circumstance that legally permits departure from primary evidence.
Part III — Section 108: Accused Invoking General Exceptions
Section 108 is the evidence-law counterpart of the General Exceptions in Sections 14–44 BNS. Where an accused claims that the case falls within a General Exception, a special exception, or a proviso contained elsewhere in the BNS or another law defining the offence, the burden of proving the circumstances bringing the case within that exception lies on the accused. The court shall presume the absence of those circumstances unless established.
The section does not mean that the prosecution is excused from proving the offence. It operates after identifying the prosecution’s ingredients and the distinct factual basis of the claimed exception.
| Question | Prosecution | Accused invoking exception |
|---|---|---|
| Did accused commit the prohibited act with required mental element? | Must establish offence ingredients | May challenge prosecution proof |
| Did statutory insanity/unsoundness exception apply? | Not generally required to disprove in advance without factual basis | Section 108 places burden of exception circumstances on accused |
| Was private defence available? | Still must prove prosecution case | Must establish factual circumstances supporting the exception |
Part IV — Section 109: Facts Especially Within Knowledge
Section 109 provides that when a fact is especially within the knowledge of a person, the burden of proving that fact is upon that person. The rule reflects practical fairness: where one side has peculiar access to a fact that the other side cannot reasonably be expected to prove directly, the law may place the explanatory burden on the person possessing that special knowledge.
But the provision is frequently overstated in criminal litigation. It is not a substitute for investigation, and it cannot be used to turn every unexplained circumstance into proof of guilt.
The Supreme Court reiterated, while discussing the predecessor Section 106 Evidence Act, that the initial burden remains on the prosecution. The special-knowledge provision does not modify the ordinary criminal rule placing the onus of proving guilt on the State.
The Court stressed that the rule cannot be invoked to make up for the prosecution’s inability to prove circumstances pointing to guilt. It becomes relevant only after the prosecution has discharged its initial onus and established facts from which a reasonable inference concerning guilt can arise.
Illustration: Death Inside a Shared Home
Suppose a death occurs inside premises occupied by the accused and deceased. The accused may possess special knowledge about what happened inside. Yet the prosecution must first establish the nature of death, relevant circumstances connecting the accused, and the foundational chain of evidence. Only then may the absence of a credible explanation acquire evidentiary significance. Section 109 does not prove homicide by itself.
Part V — Sections 110–114: Special Burden Rules
| Section | Rule | Exam Point |
|---|---|---|
| 110 | Death of person known to have been alive within 30 years | Burden of proving death lies on person asserting death |
| 111 | Person not heard of for seven years | Once statutory foundation is shown, burden shifts to person asserting continued life |
| 112 | Partners, landlord/tenant, principal/agent | Established relationship is presumed to continue until termination is proved |
| 113 | Ownership | Possession can shift burden onto person denying ownership in the statutory circumstances |
| 114 | Good faith in active-confidence transactions | Party in position of active confidence bears burden of proving good faith |
Seven Years’ Absence Does Not Automatically Prove Date of Death
The rule concerning a person not heard of for seven years concerns the burden on whether the person is alive. Students should not mechanically infer that the law also fixes the precise date or moment of death. A separate factual foundation may be required where the date itself affects succession, insurance, limitation or another legal right.
Active Confidence and Good Faith
Section 114 becomes important in fiduciary or confidence-based transactions. Where one party occupies a position of active confidence, that party may have to establish that the transaction was in good faith. This is a statutory recognition that informational and relational inequality can justify a different burden allocation.
Part VI — May Presume, Shall Presume and Conclusive Proof
Before reading Sections 115–120, students must understand the three statutory levels of presumptive effect contained in the BSA definitions.
The court has discretion: it may regard the fact as proved unless disproved, or may call for proof.
Once the statutory foundation is established, the court must regard the fact as proved unless it is disproved.
Once the foundational fact is established, the law does not permit evidence to disprove the fact declared conclusive, subject to the statute’s own exception.
Part VII — Sections 115–120: Statutory Presumptions
Section 115: Presumption as to Certain Offences
Section 115 creates a special presumption for specified offences committed in an area declared disturbed under the statutory framework and in the factual circumstances defined by the section. Because this is a specialised presumption with precise statutory preconditions and specified offences, it should be applied from the exact text rather than reduced to a broad proposition that presence in a disturbed area proves guilt.
For an exam answer, identify the notification/status of the area, the specified offence, the statutory factual conditions and the precise fact that the court is directed to presume.
Section 116: Birth During Marriage — Conclusive Proof of Legitimacy
Section 116 treats birth during the continuance of a valid marriage, or within the statutory period after its dissolution while the mother remains unmarried, as conclusive proof of legitimacy, unless it can be shown that the parties to the marriage had no access to each other at the relevant time.
The provision is important because it illustrates the strongest form of statutory evidentiary rule: once the foundational conditions exist, the court does not merely draw a rebuttable inference in the ordinary way. The statute itself defines the narrow route by which the conclusion may be displaced.
Section 117: Abetment of Suicide by a Married Woman — “May Presume”
Where a married woman commits suicide within seven years of marriage and it is shown that her husband or his relative subjected her to cruelty, Section 117 permits the court, having regard to all other circumstances of the case, to may presume that the suicide was abetted by the husband or relative.
Section 118: Dowry Death — “Shall Presume”
Section 118 is stronger. Where the question is whether a person committed the dowry death of a woman and it is shown that soon before her death she was subjected by that person to cruelty or harassment for, or in connection with, a demand for dowry, the court shall presume that the person caused the dowry death.
The presumption therefore does not arise from marriage or death alone. The prosecution must first prove the statutory foundational facts, particularly the dowry-linked cruelty or harassment and its required temporal relationship with the death.
Section 119: Court May Presume Existence of Certain Facts
Section 119 is a broad common-sense provision. The court may presume the existence of a fact that it thinks likely to have happened, having regard to the common course of natural events, human conduct and public or private business in relation to the facts of the particular case.
Its illustrations are among the most important in evidence law because they show how ordinary experience enters judicial reasoning without turning inference into speculation.
Possession of stolen property soon after theft may support an inference that the possessor is the thief or knew it was stolen, unless satisfactorily explained.
The court may treat an accomplice as unworthy of credit unless corroborated in material particulars, subject to the statutory context.
The court may presume that judicial and official acts have been regularly performed.
Evidence that could be and is not produced may be presumed to be unfavourable to the person withholding it.
Adverse Inference Is Not Automatic
The adverse-inference illustration is powerful but contextual. The court should consider whether the evidence existed, whether the party had control or ability to produce it, whether a satisfactory reason for non-production exists, whether the fact is material and what other evidence is already on record. Section 119 says the court may presume; it does not command punishment for every missing document.
For digital records, this may intersect with preservation and authenticity issues discussed in our electronic-evidence guide. Failure to preserve original CCTV, server logs or a complete chat can affect both admissibility analysis and the inference the court is invited to draw.
Section 120: Presumption as to Absence of Consent in Certain Rape Prosecutions
Section 120 applies in the rape prosecution identified by the provision. Where sexual intercourse is proved and the question is whether it occurred without the woman’s consent, if the woman states in her evidence before the court that she did not consent, the court shall presume that she did not consent.
The provision illustrates an important structural point: a statutory presumption operates only after its foundational facts are established. It should not be described as a presumption that every allegation is true or that every element of the offence is automatically proved.
Presumptions at a Glance
| Section | Subject | Effect | Foundation First? |
|---|---|---|---|
| 116 | Legitimacy | Conclusive proof, subject to statutory no-access exception | Yes |
| 117 | Abetment of suicide by married woman | May presume | Yes — suicide within seven years + cruelty + surrounding circumstances |
| 118 | Dowry death | Shall presume | Yes — soon-before dowry-linked cruelty/harassment |
| 119 | Natural events, human conduct, business | May presume | Yes — context determines whether inference is justified |
| 120 | Absence of consent in specified rape prosecution | Shall presume | Yes — statutory offence/context, intercourse and woman’s evidence of no consent |
Part VIII — Sections 121–123: Estoppel
Section 121: General Estoppel
Where one person, by declaration, act or omission, intentionally causes or permits another person to believe a thing to be true and to act upon that belief, neither that person nor the person’s representative may, in a suit or proceeding between them, deny the truth of that thing.
A useful estoppel analysis asks four questions:
- Was there a representation by declaration, act or omission?
- Was it intended or permitted to induce belief?
- Did the other person actually act on that belief?
- Is the maker now trying to deny the represented fact in a dispute between the relevant parties?
Estoppel vs Admission
An admission is relevant evidence and, under Section 25, is not ordinarily conclusive proof. Estoppel is different: where its elements are satisfied, the party is prevented from denying the represented fact in the relevant proceeding. An admission may sometimes furnish the factual basis for an estoppel, but the doctrines are not identical.
| Point | Admission | Estoppel |
|---|---|---|
| Primary role | Evidence suggesting an inference | Rule preventing inconsistent denial after reliance |
| Conclusive? | Not ordinarily; Section 25 | Operates as a bar to denial when statutory elements are satisfied |
| Reliance required? | Not an element of every admission | Yes — other person must act on induced belief |
Section 122: Estoppel of Tenant and Licensee
Section 122 prevents a tenant of immovable property, and persons claiming through the tenant, from denying that the landlord had title at the beginning of the tenancy during its continuance. A similar rule applies to a person who entered immovable property by licence in relation to the title of the person who granted the licence when it was given.
The rule is based on consistency: a person who obtained possession through another cannot ordinarily accept that source of possession and simultaneously deny the source-title at the relevant starting point while retaining the benefit of the relationship.
Section 123: Acceptor, Bailee and Licensee
Section 123 contains special estoppel rules relating to the acceptor of a bill of exchange, a bailee and a licensee. The common principle is that a person who received a legal benefit, instrument or possession on an accepted basis is restricted from later denying the foundational authority or title in the manner prohibited by the section.
Part IX — How to Solve a Burden-of-Proof Problem Question
- Identify the fact in issue. What proposition must be established for the right, liability or offence?
- Apply Section 104. Who asserts the fact on which judgment depends?
- Use the Section 105 no-evidence test. Who would fail if both sides led nothing?
- Separate particular facts. Does Section 106 place a burden concerning a discrete factual assertion?
- Check admissibility foundations. Does Section 107 require a preliminary fact before the evidence can be received?
- If accused invokes an exception, apply Section 108. Identify the exact General Exception or special proviso and its factual ingredients.
- For special knowledge, apply Section 109 cautiously. Has the prosecution or opposing party first proved the necessary foundational circumstances?
- Check Sections 110–114. Is there a statutory rule concerning life/death, relationship, ownership or good faith?
- Identify any presumption. Is it may presume, shall presume or conclusive proof?
- Prove foundational facts before invoking the presumption.
- Consider Section 119 inference. Is an inference from human conduct, business practice, recent possession, official regularity or withheld evidence justified?
- If representation and reliance are involved, test estoppel under Sections 121–123.
- Conclude separately on burden, presumption and ultimate proof. A shifted onus is not automatically a final finding of liability or guilt.

The burden-of-proof chapter is best understood as a system for allocating evidentiary responsibility, not as a set of shortcuts to judgment. Sections 104–109 identify who must establish the general case, particular facts, exceptions and facts especially within knowledge. Sections 110–120 create targeted burden rules and presumptions. Sections 121–123 prevent inconsistent denial where the requirements of estoppel are satisfied.
In criminal litigation, the central discipline is to keep the prosecution’s initial burden separate from any later explanatory burden on the accused. Ravi v. State of Punjab reinforces that Section 109’s special-knowledge principle cannot repair an incomplete prosecution case.
Memory line: §104 general burden → §105 no-evidence test → §108 exceptions → §109 special knowledge → §§110–114 special burdens → §§115–120 presumptions → §§121–123 estoppel.
Academic note: This article is for legal education and examination preparation. Presumptions and evidentiary burdens are fact-sensitive and may interact with special statutes and constitutional principles. Current statutory text and full judgments should be checked before professional reliance.
