Examination of Witnesses — In-Chief, Cross-Examination, Re-Examination

Sections 137 to 154 of the Indian Evidence Act, 1872 (IEA) — re-enacted in renumbered form in the Bharatiya Sakshya Adhiniyam, 2023 (BSA) — set out the procedural framework within which the testimony of witnesses is led, tested and corroborated in Indian trials. Section 137 IEA defines the three stages of witness examination: examination-in-chief by the party calling the witness, cross-examination by the adverse party, and re-examination by the party calling the witness. The chapter then unfolds the rules governing each stage — the kinds of question that may be asked, the scope of cross-examination, the use of leading questions, the testing of the witness's credit, the impeachment of testimony, and the procedural protections that govern the witness in the witness box.

The chapter is the most procedurally important in the BSA. Every trial — civil or criminal — is built on the testimony of witnesses, and that testimony is led and tested under the framework of Sections 137 to 154 IEA. The student who masters the chapter can navigate the trial-court procedure with confidence and can identify, on any fact-pattern, the appropriate stage of examination and the rules that govern questions and answers at that stage.

Concept — three stages of witness examination

The three-stage architecture of witness examination is the procedural backbone of Indian trial practice. The party calling the witness leads him in chief, eliciting testimony favourable to the party's case. The adverse party then cross-examines the witness, testing the testimony and seeking to elicit testimony favourable to the cross-examiner's case. The original party then re-examines, addressing matters that have arisen on cross-examination and clarifying any ambiguities or apparent contradictions.

The chapter on oral testimony under the direct-evidence rule develops the substantive rule that the witness must depose to what he himself perceived. The chapter on witnesses — competency, compellability, privileged communication develops the threshold rules of competency and privilege that operate before the examination begins.

Section 137 IEA — examination-in-chief, cross-examination, re-examination

Section 137 IEA / corresponding BSA provision defines the three stages. The examination of a witness by the party who calls him shall be called his examination-in-chief. The examination of a witness by the adverse party shall be called his cross-examination. The examination of a witness, subsequent to the cross-examination, by the party who called him, shall be called his re-examination.

The provision establishes the architecture; the subsequent sections develop the rules that govern each stage. The order is fixed: examination-in-chief first, cross-examination next, re-examination last. The trial court controls the order and may, on application, direct the recall of a witness for further examination on any matter. The chapter on order and production of witnesses under Section 135 IEA develops the framework on the order in which witnesses are called.

Section 138 IEA — order of examinations

Section 138 IEA / corresponding BSA provision provides that witnesses shall be first examined-in-chief, then if the adverse party so desires cross-examined, then if the party calling him so desires re-examined. The examination and cross-examination must relate to relevant facts, but the cross-examination need not be confined to the facts to which the witness testified on his examination-in-chief. The re-examination shall be directed to the explanation of matters referred to in cross-examination; and, if new matter is, by permission of the court, introduced in re-examination, the adverse party may further cross-examine upon that matter.

The provision gives cross-examination a significant procedural advantage: the cross-examiner is not confined to the matters covered in chief, but may explore any relevant fact bearing on the witness's testimony, on his credit, or on the case generally. The provision also permits new matter to be introduced in re-examination only with the court's permission, and triggers a further cross-examination on that matter to ensure fairness.

Section 139 IEA — cross-examination of person called to produce a document

Section 139 IEA / corresponding BSA provision provides that a person summoned to produce a document does not become a witness by the mere fact that he produces it, and cannot be cross-examined unless and until he is called as a witness. The provision is significant in trial practice: the proponent of a document may secure its production by summons without exposing the producer to cross-examination, provided the producer is not called as a witness. Where the producer is called as a witness, full cross-examination is permitted.

Section 141 IEA — leading questions

Section 141 IEA / corresponding BSA provision defines a leading question as any question suggesting the answer which the person putting it wishes or expects to receive. Sections 142 and 143 IEA then govern when leading questions may and may not be asked. Leading questions must not, if objected to by the adverse party, be asked in examination-in-chief or in re-examination, except with the permission of the court. Leading questions may be asked in cross-examination.

The chapter on leading questions and their permissibility develops the framework on leading questions in detail, including the recognised exceptions to the prohibition on leading in chief — questions of an introductory or undisputed nature, questions on matters as to which the witness has shown himself hostile, and questions where the witness is a child or otherwise needs leading to comprehend the matter.

Sections 145 and 146 IEA — cross-examination as to previous statements and questions to test the witness

Section 145 IEA / corresponding BSA provision provides that a witness may be cross-examined as to previous statements made by him in writing or reduced into writing, and relevant to matters in question, without such writing being shown to him, or being proved; but if it is intended to contradict him by the writing, his attention must, before the writing can be proved, be called to those parts of it which are to be used for the purpose of contradicting him. The provision is the principal mechanism by which previous inconsistent statements are used to impeach the witness's testimony at trial.

Section 146 IEA / corresponding BSA provision permits questions in cross-examination directed at four purposes: (i) to test the witness's veracity; (ii) to discover his position in life; (iii) to shake his credit by injuring his character; and (iv) to elicit facts about the witness's character relevant to the assessment of his testimony. The cross-examiner is given wide latitude to test the witness, but the questions must be relevant and the trial court has the discretion to disallow questions that are oppressive, irrelevant or designed only to insult.

Section 147 IEA — questions a witness is bound to answer

Section 147 IEA / corresponding BSA provision provides that if any question put to a witness relates to a matter relevant to the suit or proceeding, the witness shall be bound to answer it, subject only to the privileges of Sections 122 to 132 IEA. The provision is the operational counterpart of Section 132 IEA on the no-incrimination compulsion: the witness must answer relevant questions, with the proviso that the answers cannot be used against him criminally except for perjury.

Sections 148 to 152 IEA — questions on collateral matters

Sections 148 to 152 IEA / corresponding BSA provisions deal with questions on collateral matters. Section 148 IEA provides that the court is to decide when questions shall be asked and when witnesses are to be compelled to answer. Section 149 IEA prohibits questions without reasonable grounds — counsel cannot ask scandalous or insulting questions without reasonable grounds. Section 150 IEA provides for procedure when questions are asked without reasonable grounds — the court may report the matter to the High Court or other authority. Section 151 IEA empowers the court to forbid indecent and scandalous questions. Section 152 IEA empowers the court to forbid questions intended to insult or annoy.

Together these provisions vest the trial court with the discretion to control the conduct of cross-examination and to prevent abuse of the witness through irrelevant, scandalous or oppressive questioning. The chapter on character evidence in civil and criminal cases under Sections 46 to 50 BSA develops the related framework on the limited admissibility of character evidence.

Section 153 IEA — exclusion of evidence to contradict answers to questions testing veracity

Section 153 IEA / corresponding BSA provision provides that when a witness has been asked and has answered any question which is relevant to the inquiry only insofar as it tends to shake his credit by injuring his character, no evidence shall be given to contradict him; but, if he answers falsely, he may afterwards be charged with giving false evidence. The provision is the rule against contradiction on collateral matters: the cross-examiner who attacks the witness's credit by questions on collateral matters cannot lead independent evidence to contradict the answers; he must accept the answers and proceed.

The provision contains two recognised exceptions: where the witness denies a previous conviction, evidence may be given to contradict him; and where the witness denies any matter from which an inference of partiality, bias or interest may be drawn, evidence may be given to contradict him. These exceptions recognise that previous convictions and bias are sufficiently important to justify independent contradiction even though the underlying matter may technically be collateral.

Section 154 IEA — questions by party to his own witness

Section 154 IEA / corresponding BSA provision provides that the court may, in its discretion, permit the person who calls a witness to put any questions to him which might be put in cross-examination by the adverse party. The provision is the principal route by which a hostile witness is cross-examined by the side that called him. Where the witness has shown himself hostile — by giving evidence contrary to the case of the side calling him — the trial court may grant leave to the calling side to cross-examine, including by leading questions, on the strength of the section.

The chapter on hostile witness — concept, procedure, evidentiary value develops the framework on hostile-witness procedure in detail, including the threshold for declaring a witness hostile and the evidentiary value of testimony given by a hostile witness on cross-examination by his own side.

Operational architecture in trial practice

In trial practice in the Indian civil and criminal courts under the BSA framework, the examination of witnesses unfolds in a tightly choreographed sequence familiar to every trial-court practitioner. The proponent of the witness calls him to the witness box; the trial court conducts a brief voir dire if competency is in question on the facts known to the court; the witness is then sworn on the appropriate oath; the proponent then leads the witness in chief, eliciting the substantive testimony in the witness's own words and ensuring that the entire substance of the witness's perception of the facts in issue is placed on the trial-court record. The opposing counsel then cross-examines the witness, testing the testimony, eliciting concessions, putting the case for the cross-examining side, and impeaching the credit through prior inconsistent statements and bias. The proponent then re-examines, addressing matters arising on cross-examination and clarifying any apparent contradictions.

The chapter on the order in which witnesses are produced develops the framework on the order in which witnesses are called and on the rules of recall and further examination during the trial. The chapter on refreshing memory and cross-examination on documents develops the related framework on the witness's use of documents to refresh memory and on cross-examination on documentary evidence.

Distinguishing examination-in-chief from cross-examination — strategic considerations

Examination-in-chief is conducted by the side calling the witness; the witness is presumed friendly to that side; leading questions are generally not permitted. The purpose is to elicit the witness's substantive testimony in support of the calling side's case. Cross-examination is conducted by the adverse side; the witness is presumed not friendly; leading questions are generally permitted. The purpose is to test the witness's testimony, to elicit testimony favourable to the cross-examining side, and to impeach the witness's credit where possible.

Re-examination is conducted by the calling side after cross-examination; it is confined to matters arising on cross-examination unless the court permits new matter; its purpose is to repair the damage caused by cross-examination and to clarify ambiguities. The chapter on burden of proof and standard of proof in trial develops the burden framework that interacts with the strategic considerations of witness examination.

BSA-specific changes — minor cosmetic only

The BSA reproduces Sections 137 to 154 IEA in renumbered form without substantive change. The three-stage architecture of examination is preserved; the rules on leading questions are preserved; the cross-examination-as-to-credit framework is preserved; the rule against contradiction on collateral matters under Section 153 IEA is preserved; the hostile-witness procedure under Section 154 IEA is preserved. The classical case law on the conduct of witness examination, on the scope of cross-examination, on the impeachment of witnesses, and on the recall of witnesses continues to govern the renumbered sections without doctrinal variation. For the side-by-side mapping see our IEA to BSA section-mapping table.

Common pitfalls in answer scripts

Three errors recur and they trip up even mains candidates.

First, treating cross-examination as confined to matters covered in chief. It is not. Section 138 IEA expressly states that cross-examination need not be confined to the facts to which the witness testified on his examination-in-chief. The cross-examiner may explore any relevant fact bearing on the witness's testimony, on his credit, or on the case generally.

Second, treating Section 153 IEA's rule against contradiction as absolute. It is not. The two exceptions — previous conviction and bias — operate as recognised carve-outs, and the cross-examiner may lead independent evidence to contradict the witness's denial of either matter.

Third, treating leading questions as absolutely prohibited in chief. They are not. Section 142 IEA permits leading questions in chief on introductory or undisputed matters, on matters as to which the witness has shown himself hostile, and with the permission of the court in defined circumstances. The chapter on admissions and their evidentiary value under Sections 15 to 21 BSA develops the related framework on admissions that interacts with the leading-questions rule.

For the broader topic-cluster of Evidence Act and BSA notes — covering relevancy, oral, documentary and electronic evidence, witness examination and the BSA-specific innovations — the chapter index links to every other unit in the syllabus.

Practical drafting — preparing the witness for examination

In civil and criminal practice in the trial courts, the proponent of a witness prepares the witness for examination through a thorough briefing on the structure of the testimony, the substantive matters to be covered, and the likely lines of cross-examination. The witness must understand that his role is to depose to facts within his own perception, in his own words, and to answer cross-examination questions truthfully and concisely. The proponent must avoid coaching the witness on the substance of the testimony, but may legitimately prepare him on procedure, on the layout of the courtroom, and on the formal aspects of the examination process.

The cross-examiner prepares by analysing the witness's prior statements, identifying inconsistencies and weaknesses, and constructing a sequence of questions designed to elicit favourable testimony or to impeach the witness's credit. The chapter on proof of documents and the attesting-witness rule develops the related framework on the documentary evidence that often forms the basis of cross-examination on prior inconsistent statements and conduct.

Special protections for vulnerable witnesses

Modern Indian trial practice in the special courts and the ordinary trial courts has developed special procedural protections for vulnerable witnesses — children, victims of sexual offences, witnesses requiring witness protection under the Witness Protection Scheme. The trial court may permit the examination of such witnesses through video conferencing from a remote location, behind a screen that shields the witness from the accused in the courtroom, in camera proceedings closed to the public, or with the assistance of a support person who accompanies the witness during the testimony. The protections are designed to minimise the trauma of the trial process for the vulnerable witness while preserving the fairness of the examination procedure for both sides.

The Supreme Court has been particularly attentive to the protection of child witnesses in POCSO prosecutions and of women witnesses in sexual-offence prosecutions. The chapter on the limits of character-evidence admissibility develops the related framework on the limited admissibility of character evidence in such prosecutions, which interacts with the cross-examination rules of the present chapter to protect the witness from intrusive questioning on past life and personal history.

The role of the trial judge in controlling examination

The trial judge plays a central role in controlling the examination of witnesses. Sections 148 to 152 IEA vest the judge with the discretion to disallow questions that are scandalous, indecent, oppressive or designed only to insult or annoy. The judge is the guardian of the witness's dignity and of the fairness of the trial proceedings; his discretion is exercised throughout the examination of every witness to ensure that the testimony is led and tested within the bounds of relevance, propriety and respect for the witness as a person who has come before the court to assist in the administration of justice.

Conclusion — the chapter as the procedural heart of the trial

Sections 137 to 154 IEA and the corresponding BSA provisions together constitute the procedural heart of the Indian trial. The three-stage architecture of examination-in-chief, cross-examination and re-examination is the framework within which all testimonial evidence is led and tested. The detailed rules on leading questions, on cross-examination as to credit, on questions on collateral matters, on the rule against contradiction, and on the hostile-witness procedure together ensure that the testimony of witnesses is received fairly, tested rigorously, and weighed accurately by the trial court. The mains aspirant who has internalised the three stages, the rules governing each stage, and the strategic considerations that arise in trial practice will be at home in this chapter and will not be tripped up by any examination-procedure fact-pattern, however ingeniously the examiner constructs it.

Frequently asked questions

What are the three stages of witness examination under Section 137 IEA?

Section 137 IEA / corresponding BSA provision defines the three stages: (i) examination-in-chief — the examination of a witness by the party who calls him; (ii) cross-examination — the examination of a witness by the adverse party; and (iii) re-examination — the examination of a witness, subsequent to the cross-examination, by the party who called him. The order is fixed and the trial court controls the procedure. Re-examination is confined to matters arising on cross-examination unless the court permits new matter, in which case the adverse party may further cross-examine on the new matter.

Can cross-examination explore matters not covered in examination-in-chief?

Yes. Section 138 IEA expressly provides that cross-examination need not be confined to the facts to which the witness testified on his examination-in-chief. The cross-examiner may explore any relevant fact bearing on the witness's testimony, on his credit, or on the case generally. The provision gives cross-examination a significant procedural advantage and is the principal mechanism by which the testimony of a witness is tested for accuracy, completeness and credibility in the trial process.

When may leading questions be asked under the BSA?

Sections 142 and 143 IEA / corresponding BSA provisions govern leading questions. Leading questions must not, if objected to by the adverse party, be asked in examination-in-chief or in re-examination, except with the permission of the court. The court will permit leading in chief on introductory or undisputed matters, on matters as to which the witness has shown himself hostile, on questions to a child witness who needs leading to comprehend the matter, and in other defined circumstances. Leading questions may be asked freely in cross-examination, where they are the principal mode of testing the witness.

What is the rule against contradiction on collateral matters under Section 153 IEA?

Section 153 IEA / corresponding BSA provision provides that when a witness has been asked and has answered any question which is relevant to the inquiry only insofar as it tends to shake his credit by injuring his character, no evidence shall be given to contradict him; if he answers falsely, he may be charged with perjury. The provision contains two exceptions: where the witness denies a previous conviction, and where the witness denies any matter from which an inference of partiality, bias or interest may be drawn — in both cases independent evidence may be led to contradict the witness.

How is a hostile witness handled under Section 154 IEA?

Section 154 IEA / corresponding BSA provision permits the trial court, in its discretion, to allow the person who calls a witness to put any questions to him which might be put in cross-examination by the adverse party. Where the witness has shown himself hostile by giving evidence contrary to the case of the side calling him, the trial court grants leave to the calling side to cross-examine, including by leading questions. The evidentiary value of the testimony of a hostile witness is reduced but not destroyed; the court weighs the testimony with caution and may rely on parts of it that are corroborated by other evidence.
