Exceptions to Onus Probandi — Exceptions, Facts Especially Within Knowledge, and Good Faith (ss. 107–109, 114) — BSA (Law of Evidence) Notes

Exceptions to Onus Probandi — Exceptions, Facts Especially Within Knowledge, and Good Faith (ss. 107–109, 114)

A ticket inspector finds a man in the compartment with no ticket. The man says “I bought one.” Must the railway prove the negative — that he did not buy a ticket, tracing every window at every station? That would be absurd. The law’s answer is simple and centuries old: the fact of whether he bought a ticket is locked inside the passenger’s own head and pocket, so he must prove it. This little problem is the most-repeated fact-pattern in Unit 4, and it turns on one section — s. 109.

The last topic gave the general rule: he who asserts must prove (ss. 104–106). But a general rule that never bent would sometimes force a party to prove the impossible. So the Adhiniyam carves out exceptions — situations where the burden is placed on the party best able to discharge it, whatever the general rule would say. Four sections matter.

A. Facts to be proved to make evidence admissible — s. 107

Section 107 (old IEA s. 104) is the housekeeping rule: the burden of proving any fact that a person must prove in order to make his evidence of some other fact admissible lies on that person. If A wants to give secondary evidence of a lost document, A must first prove the fact of loss — because that fact is what unlocks the door to his evidence. It rarely appears in a problem on its own, but it completes the set.

B. Burden of proving a case within an exception — s. 108

Section 108 (old IEA s. 105) deals with the accused who pleads a defence. When a person is accused of an offence, the burden of proving that his case falls within any of the General Exceptions in the Bharatiya Nyaya Sanhita (the old IPC — insanity, private defence, grave and sudden provocation, accident) — or within any special exception or proviso — lies on him, and the court shall presume the absence of such circumstances.

Two limits keep this from swallowing Woolmington:

The accused proves the exception only on a preponderance of probabilities, not beyond reasonable doubt. He need only make his defence probable.
The prosecution’s burden to prove the offence itself, beyond reasonable doubt, never shifts. Section 108 shifts only the burden of the exception, not of the guilt.

C. Facts especially within knowledge — s. 109

Section 109 (old IEA s. 106) is the one the problems test: when any fact is especially within the knowledge of any person, the burden of proving that fact is upon him. The section exists precisely because it would be unreasonable to make the other side prove a fact that only one person could possibly know. The illustration in the Act itself is the traveller without a ticket: whether he had a ticket is a fact especially within his knowledge, so the burden of proving it is on him.

🔑 Section 109 does not relieve the prosecution of proving the offence. It applies only to a subsidiary fact that lies peculiarly within one person’s knowledge. In the ticket case the railway must still prove the man was travelling; only the ticket — a fact he alone can establish — is thrown onto him.

D. Good faith in a transaction of active confidence — s. 114

Section 114 (old IEA s. 111) covers the fiduciary: where there is a question as to the good faith of a transaction between parties, one of whom stands to the other in a position of active confidence (a lawyer and client, a guardian and ward, a father and a son who has just attained majority), the burden of proving the good faith of the transaction is on the party who is in that position of active confidence. The dominant party — the one trusted — must show the deal was fair; the trusting party does not have to prove it was unfair.

🧩 WORKED EXAMPLE — the three exceptions in three problems

Facts. (i) P is caught on a train with no ticket and says he bought one. (ii) Q, on trial for murder, pleads he was insane at the time. (iii) A son, just turned 18, sells his land to his father for a low price and later sues to undo the sale; the father says it was a fair, good-faith deal.

Rule. A fact especially within a person’s knowledge must be proved by him (s. 109); an accused pleading an Exception must prove it on the balance of probabilities (s. 108); good faith in a transaction of active confidence must be proved by the dominant party (s. 114).

Apply. In (i) the ticket is a fact especially within P’s knowledge — P must prove it (s. 109). In (ii) insanity is a General Exception — Q must prove it, on a preponderance of probabilities, while the prosecution still proves the killing beyond reasonable doubt (s. 108). In (iii) the father stands in active confidence over a son barely of age — the father must prove the good faith of the sale (s. 114).

Conclusion. Each is an exception to “he who asserts must prove”: the burden lands on the person best placed to discharge it.

Decoy. In all three the tempting answer is the general rule (ss. 104–105 — “the plaintiff/prosecution must prove its case”). That is the planted trap; the exceptions displace it.

Section 108, BSA 2023: “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, or within any special exception or proviso… is upon him, and the Court shall presume the absence of such circumstances.”

Section 109, BSA 2023: “When any fact is especially within the knowledge of any person, the burden of proving that fact is upon him.” (Illustration: A is charged with travelling on a railway without a ticket. The burden of proving that he had a ticket is on him.)

Section 114, BSA 2023: “Where there is a question as to the good faith of a transaction between parties, one of whom stands to the other in a position of active confidence, the burden of proving the good faith of the transaction is on the party who is in a position of active confidence.”

In Simple Terms: The general rule bends in three places. If a fact is locked inside your own knowledge (the ticket), you prove it (s. 109). If you plead a defence like insanity, you prove that defence — but only that it is probable — while the State still proves the crime (s. 108). And if you are the trusted, dominant party in a relationship (the father, the guardian, the lawyer), you must prove the deal was in good faith (s. 114).

Case Laws

Shambhu Nath Mehra vs State of Ajmer (1956) — s. 106 (now s. 109) does not relieve the prosecution of its burden; it applies only to facts especially within the accused’s knowledge, not to the offence itself.
State of West Bengal vs Mir Mohammad Omar (2000) — where the accused last seen with the victim offer no explanation for a fact within their special knowledge, s. 106 (s. 109) can be pressed into service to complete the chain.
K.M. Nanavati vs State of Maharashtra (1962) — an accused pleading a General Exception (here, grave and sudden provocation / private defence) bears the burden of proving it on a preponderance of probabilities; the presumption of innocence otherwise stands.
Subramania Iyer vs Ranganatha Iyer (1968) — where a party stands in a position of active confidence, the burden of proving the good faith of the transaction lies on him (s. 111 IEA, now s. 114).
