Questions lawful in cross-examination
Testing the witness — within limits. In cross-examination a witness may be asked questions that test his truthfulness, reveal who he is, or shake his credit — even if the answer would incriminate him. But a strict bar protects a sexual-offence victim from questions about her character or sexual history to prove consent.
How to read Section 149
Cross-examination may test a witness’s truthfulness, background and credit — even on self-incriminating matters — but not a sexual-offence victim’s character or sexual history to prove consent.
Questions may tend to test his veracity, to discover who he is and his position in life, or to shake his credit by injuring his character.
These may be asked even though the answer might criminate him or expose him to a penalty or forfeiture.
In prosecutions for rape and related offences (BNS §§ 64–71) where consent is in issue, the victim may not be questioned on her character or previous sexual experience to prove consent.
The bare Act
The section in its own words — three heads of lawful cross-examination, and a protective proviso.
When a witness is cross-examined, he may, in addition to the questions hereinbefore referred to, be asked any questions which tend—
(a) to test his veracity; or
(b) to discover who he is and what is his position in life; or
(c) to shake his credit, by injuring his character, although the answer to such questions might tend directly or indirectly to criminate him, or might expose or tend directly or indirectly to expose him to a penalty or forfeiture:
Proviso.—Provided that in a prosecution for an offence under section 64, section 65, section 66, section 67, section 68, section 69, section 70 or section 71 of the Bharatiya Nyaya Sanhita, 2023 or for attempt to commit any such offence, where the question of consent is an issue, it shall not be permissible to adduce evidence or to put questions in the cross-examination of the victim as to the general immoral character, or previous sexual experience, of such victim with any person for proving such consent or the quality of consent.
In short: cross-examination is the great engine for testing a witness, and this section widens the questions that may be put. Beyond the ordinary relevant questions, a witness may be asked anything tending to (a) test his veracity — is he a truthful person; (b) discover who he is and his position in life — his identity and standing; and (c) shake his credit by injuring his character. Crucially, these credit questions may be pressed even though the answer might incriminate the witness or expose him to a penalty or forfeiture — read this with § 137, which compels the answer but gives the witness use immunity for it. The proviso then carves out a vital protection: in a prosecution for rape or a related sexual offence under sections 64 to 71 of the BNS 2023 (or an attempt), where consent is in issue, it is not permissible to lead evidence or cross-examine the victim about her general immoral character or previous sexual experience with anyone, for the purpose of proving consent or its quality. This is the rape-shield rule — a victim’s dignity is not to be attacked through her sexual history.
→ This carries forward IEA 1872 § 146 — the lawful heads of cross-examination, with the rape-shield proviso.
