The Concept and Its Roman Root

When a person walks into a court of law asserting a right or alleging a wrong, the legal system does not take his word for it. It demands proof. The ancient Roman maxim that underlies the entire chapter on burden of proof is: ei qui affirmat, non ei qui negat, incumbit probatio — the burden lies upon him who affirms, not upon him who denies. This is the philosophical bedrock on which the statutory framework rests.

The phrase burden of proof, or its Latin equivalent onus probandi, is however used in two distinct and quite different senses — a distinction that the courts have consistently emphasised and which the student must grasp clearly from the outset. The Gujarat High Court in Patel Ramanbhai Mathurbhai v Govindbhai Chhotabhai Patel (2020 1 GLH 261, affirmed by the Supreme Court in AIR 2019 SC 4822) explained it with precision: burden of proof includes both the burden of persuasion and the burden of production. The burden of persuasion is the duty to convince the fact-finder to view facts in a way that favours the person asserting them. The burden of production is the duty to introduce enough evidence on an issue so that the issue is decided in one's favour. The Supreme Court in State of Maharashtra v Wasudeo Ramchandra Kaidalwar (AIR 1981 SC 1186) added further clarity when it held that the expression "burden of proof" has two distinct meanings: first, the legal burden of establishing the guilt or the case — that never shifts; and second, the evidential burden of leading evidence — that shifts constantly as the trial progresses.

Section 101 IEA (Section 104 BSA): The Primary Rule

Section 101 of the Indian Evidence Act, 1872 — now reproduced as Section 104 of the Bharatiya Sakshya Adhiniyam, 2023 — is the cornerstone. It declares:

"Whoever desires any Court to give judgment as to any legal right or liability dependent on the existence of facts which he asserts, must prove that those facts exist. When a person is bound to prove the existence of any fact, it is said that the burden of proof lies on that person."

The illustration given by the Act is eloquent in its simplicity:

A desires a Court to give judgment that B shall be punished for a crime which A says B has committed. A must prove that B has committed the crime.

A desires a Court to give judgment that he is entitled to certain land in the possession of B, by reason of facts which he asserts. A must prove the existence of those facts.

Notice that both illustrations — one criminal, one civil — arrive at the same conclusion: the burden lies on the party who asserts, not on the party who denies. In a civil suit for possession of land, the plaintiff must prove his title. In a murder trial, the prosecution must prove that the accused committed the offence. The negative is never required to be proved — it is the affirmative that demands evidence.

The rule is adopted partly because it is just that he who invokes the machinery of law should be the first to prove his case, and partly because, in the nature of things, a negative is more difficult to establish than an affirmative.

Section 102 IEA (Section 105 BSA): On Whom Does It Lie?

While Section 101 tells us what burden of proof means, Section 102 (now Section 105 BSA) provides a practical test to determine on whom the burden falls. The section states:

"The burden of proof in a suit or proceeding lies on that person who would fail if no evidence at all were given on either side."

The illustrations illuminate this beautifully:

A sues B for land of which B is in possession, and which A asserts was left to A by the will of C, B's father. If no evidence were given on either side, B would be entitled to retain his possession. Therefore the burden of proof is on A.

Here, B wins merely by sitting still — because the law presumes that a person in possession has rightful possession. A must disturb that presumption. So the burden falls on A.

A sues B for money due on a bond. The execution of the bond is admitted, but B says it was obtained by fraud, which A denies. If no evidence were given on either side, A would succeed, as the bond is not disputed and fraud is not proved. Therefore the burden of proof is on B.

Here, A has already established his claim by virtue of the admitted bond. If B makes no further move, A succeeds. Therefore, it is B who must prove fraud. The burden shifts to the person who would otherwise lose — not as a permanent transfer, but as a practical direction.

Section 103 IEA (Section 106 BSA): Burden as to Particular Fact

Section 103 (now Section 106 BSA) amplifies Section 101 by dealing not with the burden on the whole case, but with the burden in respect of any particular fact in issue. It provides:

"The burden of proof as to any particular fact lies on that person who wishes the Court to believe in its existence, unless it is provided by any law that the proof of that fact shall lie on any particular person."

The illustration provided is a classical one:

A prosecutes B for theft and wishes the Court to believe that B admitted the theft to C. A must prove the admission. B wishes the Court to believe that at the time in question he was elsewhere. He must prove it.

This section elegantly captures the idea that every assertion — whether by the plaintiff, prosecution, or the defendant — must be proved by the person who makes it. If the prosecution wishes to rely on an admission, it must prove the admission. If the accused wishes to plead alibi, he must prove the alibi. The illustration on alibi has been applied consistently by the Supreme Court — in State of Uttar Pradesh v Sughar Singh (AIR 1978 SC 191) and again in Dudhnath Pandey v State of Uttar Pradesh (AIR 1981 SC 911), the Court held that a plea of alibi must be proved with such certainty as to completely exclude the possibility of the accused's presence at the scene of the crime.

Section 104 IEA (Section 107 BSA): Fact Preliminary to Evidence

Section 104 (now Section 107 BSA) deals with a specific and important situation where the very admissibility of a piece of evidence depends first upon proof of another foundational fact. The section provides:

"The burden of proving any fact necessary to be proved in order to enable any person to give evidence of any other fact is on the person who wishes to give such evidence."

The illustrations given are clear:

A wishes to prove a dying declaration by B. A must prove B's death.

A wishes to prove, by secondary evidence, the contents of a lost document. A must prove that the document has been lost.

A dying declaration is only admissible if the declarant is dead — it is a foundational requirement. Until death is proved, the declaration simply cannot enter the record. Similarly, secondary evidence of a document is only permissible upon proof of the document's loss. The person who wishes to take advantage of these forms of evidence must first discharge the burden of proving the gateway fact.

Section 105 IEA (Section 108 BSA): Burden on the Accused to Prove Exceptions

Section 105 (now Section 108 BSA) is one of the most contested provisions in criminal jurisprudence — for it carves out a specific departure from the general rule that the prosecution must prove everything. It provides:

"When a person is accused of any offence, the burden of proving the existence of circumstances bringing the case within any of the General Exceptions in the [Bharatiya Nyaya Sanhita, 2023 / Indian Penal Code] or within any special exception or proviso contained in any other part of the said Sanhita, or in any law defining the offence, is upon him, and the Court shall presume the absence of such circumstances."

The illustrations drive home the point:

A, accused of murder, alleges that by reason of unsoundness of mind he did not know the nature of the act. The burden of proof is on A.

A, accused of murder, alleges that by grave and sudden provocation he was deprived of the power of self-control. The burden of proof is on A.

This is a deliberate statutory choice: the prosecution need not disprove every exception — that would be an impossible task. The law places the burden of proving the exception squarely on the accused. However, and this is crucial — the standard of proof demanded of the accused is not as heavy as that demanded of the prosecution. While the prosecution must prove guilt beyond reasonable doubt, the accused need only establish his exception on a preponderance of probabilities or a balance of probabilities. The Supreme Court stated this authoritatively in MP Gupta v State of Rajasthan (AIR 1974 SC 773): the accused can discharge his burden by showing a balance of probabilities and need not establish his case beyond reasonable doubt.

Section 106 IEA (Section 109 BSA): Facts Within Special Knowledge

Section 106 (now Section 109 BSA) provides relief in another common situation — where a fact is especially within the knowledge of a party. The section provides that when any fact is especially within the knowledge of any person, the burden of proving that fact is upon him. The classic illustration in the Act deals with the ticketless traveller: if a person is found on a train without a ticket and he claims he had one, the fact of having a ticket is especially within his knowledge, and the burden lies on him to prove it.

The Supreme Court applied this principle in KN Beena v Muniyappan (AIR 2001 SC 2895) in the context of cheque bouncing under Section 138 of the Negotiable Instruments Act — the court held that since the cheque is presumed to be issued for a debt or liability, the burden lies on the accused drawer to show that no such debt existed, that being a fact especially within his knowledge.

How the Burden Shifts — The Vital Distinction

The single most important distinction for a student of evidence law to understand is this: the legal burden never shifts; the evidential burden or onus constantly shifts.

The Supreme Court in Raghavamma v Chenchamma (AIR 1964 SC 136) stated this with characteristic precision: there is an essential distinction between burden of proof and onus of proof — burden of proof lies upon the person who has to prove a fact and it never shifts, but the onus of proof shifts. Such shifting of onus is a continuous process in the evaluation of evidence.

Consider this example. A sues B for money lent, producing a promissory note. A has the legal burden — he must prove the loan. Now B admits the note but says he has repaid. The legal burden never leaves A — if the evidence at the end is in perfect equipoise, A loses. But the evidential burden has shifted: once A proves the note, B must produce evidence of repayment, or he will fail on that plea.

In a criminal trial, the prosecution's legal burden — to prove guilt beyond reasonable doubt — never shifts to the accused. As the Supreme Court held in Jarnail Singh v State of Punjab (AIR 1996 SC 755), the burden of proving guilt beyond all reasonable doubt always rests on the prosecution and on its failure, it cannot fall back upon the evidence adduced by the accused in support of his defence. The accused need only create a reasonable doubt in the mind of the court — he does not have to establish innocence.

The Concept of Reverse Burden

A departure from the general rule is the concept of reverse burden of proof, where the statute itself places the initial legal burden on the accused rather than on the prosecution. This is different from the onus under Section 105, which only requires the accused to prove a specific defence he pleads after the prosecution has established its case. In reverse burden, the law raises a presumption of guilt from certain proved facts and requires the accused to rebut it.

Section 114, illustration (a) of the Evidence Act is an early example: a man found in possession of stolen goods soon after the theft may be presumed to be either the thief or a receiver of stolen goods — the burden shifts to him to explain his possession. Under the NDPS Act, the Prevention of Corruption Act (Section 20), and the Dowry Prohibition Act, the reverse burden operates more explicitly. The Supreme Court in Harendra Sarkar v State of Assam (AIR 2008 SC 2467) cautioned that reverse burden should not be applied by courts unless it is expressly imposed by statute, as it fundamentally encroaches upon the presumption of innocence that is a facet of Article 21 of the Constitution.

When Burden Becomes Academic

One final principle deserves attention. When both parties have fully led their evidence and the entire evidentiary material is before the court, the Supreme Court has repeatedly held in Narayan Bhagwantrao Gosavi Balajiwale v Gopal Vinayak Gosavi (AIR 1960 SC 100) and Ramji Dayawala Sons Pvt. Ltd. v Invest Import (AIR 1981 SC 2085) that the question of burden of proof becomes academic — the court simply weighs the totality of the evidence and decides which version is more probable. Abstract questions of burden only matter when one side fails to produce any evidence at all, or when the scales remain perfectly balanced at the end of the trial.

The law of burden of proof, in short, is a mirror of the foundational principle of any civilised legal order: a person who asserts must prove, a person who seeks relief must earn it, and the machinery of justice is activated only by the party who knocks at its door.
