A witness summoned to produce a document must bring it before the Court if it is in the witness's possession or power, despite objections to production or admissibility. The Court decides such objections and may inspect the document or receive other evidence to determine admissibility, except where the document concerns matters of State. Where translation is necessary, secrecy may be directed unless the document is to be given in evidence.

Section 161 requires production and inspection, on the adverse party's request, of any writing used by a witness under the preceding memory-refreshing provisions. The adverse party may cross-examine the witness concerning that writing. Application of this right to police diaries is governed in connection with the separate provision addressing such diaries.

A witness may testify to facts stated in a document of the kind referred to in section 159 despite lacking specific recollection, if satisfied that the facts were correctly recorded. A book-keeper may testify about transactions recorded in regularly maintained business books if the book-keeper knows that the books were correctly kept, notwithstanding forgotten individual transactions.

Refreshing memory permits a witness under examination to consult a contemporaneous or shortly subsequent writing made personally, where the matter remained fresh in memory. A writing made by another person may also be used if it was read within that period and known to be accurate. A copy may be consulted with the Court's permission upon sufficient reason for non-production of the original. Experts may refer to professional treatises.

Export Declaration Form compliance is generally required from 1 October 2026 for exports of goods and services. At electronic data interchange ports, a Shipping Bill serves as the goods export declaration. Service exporters generally file EDF within 30 days after the invoice month ends and may use a consolidated monthly EDF. Software exports move from the separate SOFTEX process into the EDF framework, subject to applicable exemptions and special provisions.

Proved statements relevant under sections 32 or 33 may be contradicted or corroborated, and the maker's credit may be impeached or confirmed. Matters may be proved where they could have been proved if the maker had been called as a witness and had denied the suggested matter on cross-examination. This enables testing of both the statement's reliability and the maker's credibility.

Corroboration of witness testimony permits proof of a witness's former statement concerning the same fact when made at or about the time of the occurrence, or before an authority legally competent to investigate that fact. The earlier statement may be proved in evidence to support the witness's later testimony, and its corroborative use requires both statements to relate to the same fact.

Section 156 permits questions to a witness intended to be corroborated about circumstances observed at or near the time or place of a relevant fact, where proof of those circumstances would support the witness's testimony. Independent evidence of collateral incidents connected by time or place may corroborate an accomplice's account of a robbery, including incidents occurring while travelling to or from the location.

Section 155 permits impeachment of a witness's credit by the adverse party, or by the calling party with the Court's consent. Permitted methods include reputation evidence from persons acquainted with the witness, proof of bribery or other corrupt inducement, and proof of former inconsistent statements concerning evidence liable to contradiction. Reasons for a credibility witness's belief may be elicited only in cross-examination, and the resulting answers cannot be contradicted, though false answers may support a charge of giving false evidence.

Section 154 permits the person who calls a witness, subject to the Court's discretion, to ask questions that could be put by the adverse party in cross-examination. Permission is discretionary. Reliance on any part of the witness's evidence remains available despite permission to conduct such questioning under sub-section (1).

Section 153 restricts extrinsic evidence used to contradict a witness's answers to questions relevant only for shaking credibility by injuring character. Contrary evidence is generally excluded after such an answer, though a false answer may expose the witness to a charge of giving false evidence. Contradiction remains permissible for denied previous convictions, facts impeaching impartiality, or material facts in issue rather than mere character or credit.

The Court must forbid questions that appear intended to insult or annoy a witness. Questions that may be proper in subject matter must also be excluded where their form is needlessly offensive, preventing abusive or unnecessarily disparaging questioning during examination of witnesses.

Section 151 of the Indian Evidence Act, 1872 permits the Court to forbid questions or inquiries regarded as indecent or scandalous during examination of witnesses, even where they bear on matters before it. Such questioning remains permissible where it relates to facts in issue or is necessary to determine whether those facts existed.

Questions asked without reasonable grounds during witness examination may lead the Court to report the circumstances to the High Court or other professional authority where the question was asked by a barrister, pleader, vakil or attorney subject to that authority's professional oversight. The power to report is discretionary and depends on the Court's opinion that reasonable grounds were absent.

Questions conveying imputations against a witness require reasonable grounds for believing the allegation is well-founded. Speculative or random accusations are not proper. Such grounds may arise from professional instructions or from court information supported by satisfactory reasons. Where nothing is known about a witness, an accusation made at random lacks a proper basis; however, unsatisfactory answers about the witness's lifestyle and means of living may justify further questioning.

The Court controls whether a witness may be compelled to answer questions unrelated to the proceeding that affect credibility by injuring character. Questions are proper where the imputation, if true, would seriously affect credibility. They are improper where the imputation is remote, has little bearing on credibility, or is disproportionate to the importance of the witness's evidence. A refusal to answer may support an unfavourable inference.

Section 147 governs when a witness is to be compelled to answer a question in examination. Where a question relates to a matter relevant to the suit or proceeding, the provisions applicable under section 132 apply to that question for purposes of compulsion. The statutory scheme links relevance to the application of the section 132 provisions.

Cross-examination permits questions testing a witness's veracity, establishing identity and social position, or impairing credibility, even where answers may incriminate the witness or expose the witness to a penalty or forfeiture. In specified rape prosecutions involving consent, the victim's general immoral character or prior sexual experience cannot be used in cross-examination or evidence to prove consent or its nature.

Cross-examination on a witness's previous written statements is permitted when relevant to matters in question, without first showing or proving the writing. If the writing is intended to contradict the witness, the witness's attention must first be drawn to the specific portions proposed for contradiction before the writing may be proved for that purpose. Application to police diaries is governed by the separate procedural framework for such diaries.

Evidence as to matters in writing restricts oral testimony concerning contracts, grants, dispositions of property, or document contents where production is required. An adverse party may object until the document is produced or entitlement to secondary evidence is established. Statements by others about document contents may nevertheless be proved orally when independently relevant, including to demonstrate motive.
