Introduction
Every witness who has ever taken the stand in an Indian courtroom has moved through the same three-stage sequence, in the same fixed order, governed by the same short provision. It rarely gets cited directly in judgments the way flashier sections do, but it is the scaffolding that every other rule in this chapter — leading questions, contradiction by prior statement, character testing, and more — is built on top of.
Section 143 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA), in Chapter X ("Of the Examination of Witnesses"), lays down the order of examination itself: examination-in-chief, then cross-examination, then re-examination — and the distinct rules governing what each stage may properly cover. This article works through all three parts, a Supreme Court ruling on why the sequence cannot be skipped, and how Section 143 functions as the structural spine for the other provisions already covered in this series.
143. Order of examinations.
(1) 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.
(2) The examination-in-chief 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.
(3) 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.
Subsection (1): A Fixed Sequence, Not a Suggestion
The first subsection sets the order every witness follows: examination-in-chief always comes first, by the party who called the witness. Cross-examination follows only if the adverse party chooses to exercise it. Re-examination follows only if the calling party chooses to exercise it, and only after cross-examination has actually occurred. This sequence is mandatory — a court cannot rearrange it, and skipping a stage that a party has properly invoked is a procedural defect, not a matter of judicial convenience.
The Sequence Cannot Be Skipped: A Supreme Court Reminder
The importance of following this order strictly was underlined by a bench of the Supreme Court comprising Justice Abhay Oka and Justice Ujjal Bhuyan, which held that recording only a witness's examination-in-chief without also recording the cross-examination that a party is entitled to is contrary to law, expressly invoking Section 138 of the old Indian Evidence Act — the BSA's Section 143. The ruling is a reminder that Section 143's sequence is not a mere administrative convenience for trial courts; a truncated examination that denies a party the cross-examination stage this section guarantees can taint the resulting testimony's validity.
Subsection (2): Why Cross-Examination Is Allowed to Roam
Subsection (2) draws a deliberate asymmetry between the first two stages. Examination-in-chief must stick to relevant facts — and, practically, tends to stay close to the specific matters the calling party wants the witness to establish. Cross-examination, while it too must relate to relevant facts, is explicitly freed from any requirement to stay confined to whatever the witness covered in chief.
This asymmetry exists because cross-examination serves two distinct functions that examination-in-chief does not: testing, weakening, or undermining the opposing party's case, and — just as importantly — building the cross-examining party's own case through the opponent's witness. A witness who was only asked about event A in chief can still be cross-examined about events B and C, so long as B and C are themselves relevant facts in the proceeding.
Subsection (3): Re-Examination's Narrower Job, and the Escape Valve
Where cross-examination is deliberately unconfined, re-examination is deliberately narrow: it must be directed at explaining matters that came up during cross-examination. A party cannot use re-examination as a second bite at examination-in-chief to introduce fresh, unrelated ground.
Subsection (3) does provide one escape valve: if the court permits genuinely new matter to be introduced during re-examination — something beyond mere explanation of cross-examination topics — the adverse party regains the right to further cross-examine specifically on that new matter. This prevents the narrow purpose of re-examination from being quietly stretched into a backdoor for unrebutted new evidence.
Worked Example: All Three Subsections in One Trial
A prosecution witness is examined-in-chief about seeing the accused near the scene at 9 p.m. On cross-examination, defence counsel — under subsection (2) — is not confined to the 9 p.m. sighting and asks broader questions about the witness's relationship with the victim, a matter never raised in chief but relevant to possible bias. In re-examination, the prosecution — under subsection (3) — may only ask the witness to clarify or explain that relationship testimony, not introduce an unrelated new sighting. If the court permits the prosecution to introduce a genuinely new fact during re-examination — say, a second sighting the witness had not mentioned before — defence counsel regains the right to cross-examine specifically on that new sighting.
Section 143 as the Spine of This Chapter
Section 143 is not an isolated rule — it is the structural framework that the other provisions covered in this series operate within. Section 146 BSA's rules on leading questions depend entirely on knowing which of Section 143's three stages a question is asked in. Section 148 BSA's contradiction procedure and Section 149 BSA's permissible cross-examination subject matter both presuppose the cross-examination stage that Section 143 defines and authorises. Section 145 BSA's confirmation that character witnesses face ordinary examination only makes sense against the three-stage order Section 143 establishes as the default for every witness. Understanding Section 143 first is what makes the rest of this chapter's more specific rules intelligible as a coherent system rather than a list of disconnected provisions.
| Related Provision | How It Depends on Section 143's Framework |
|---|---|
| Section 146 BSA (Leading Questions) | Applies different rules depending on which of Section 143's three stages is underway |
| Section 148 BSA (Contradiction by Prior Writing) | Operates specifically within the cross-examination stage Section 143 authorises |
| Section 149 BSA (Lawful Cross-Examination Questions) | Defines subject-matter limits within the cross-examination stage Section 143 creates |
Section 143 BSA vs. Section 138 IEA: No Substantive Change
Section 143 corresponds to Section 138 of the Indian Evidence Act, 1872 (IEA). The BSA presents the same content in three clearly numbered subsections rather than continuous paragraphs, but the substance — the fixed order, the relevance requirement, the unconfined scope of cross-examination, and the narrower, explanation-directed scope of re-examination with its further-cross-examination escape valve — is carried forward entirely unchanged.
Who Section 143 Actually Affects
- Every trial lawyer operates within this three-stage sequence for every witness, whether or not the section is ever cited by name.
- Cross-examining counsel can range well beyond the topics covered in chief, so long as the new ground is itself relevant to the case.
- Parties conducting re-examination must confine themselves to explaining cross-examination matters, not smuggling in fresh evidence.
- Trial judges must ensure the sequence is followed in full, since truncating it — particularly denying a party its cross-examination opportunity — has been held contrary to law.
- Appellate courts reviewing the record should check that the order and scope rules in all three subsections were actually respected before relying on the resulting testimony.
Key Takeaways
- The three-stage order is mandatory: examination-in-chief, then cross-examination (if invoked), then re-examination (if invoked) — in that sequence, without exception.
- Skipping cross-examination is a legal defect, not a shortcut: the Supreme Court has held that recording only examination-in-chief, without the cross-examination a party is entitled to, is contrary to law.
- Cross-examination is deliberately unconfined: it need not stick to the topics raised in chief, reflecting its dual role of attacking the opponent's case and building the cross-examiner's own.
- Re-examination is deliberately narrow, with one escape valve: it must explain cross-examination matters, but genuinely new material admitted with court permission reopens further cross-examination on that specific point.
- Section 143 is the structural spine of this chapter: Sections 145, 146, 148, and 149 all operate within, and depend on, the three-stage framework it establishes.
Conclusion
Section 143 rarely makes headlines, but it is the quiet architecture underneath almost everything else in this chapter — the fixed order that turns a witness's appearance into a structured, testable process rather than an unstructured conversation. Its asymmetry between an unconfined cross-examination and a narrowly directed re-examination reflects a considered judgment about where the risks of unfairness actually lie at each stage.
Having worked backward through Sections 149 down to 143 in this run, the shape of the chapter becomes clear: Section 143 supplies the sequence, and Sections 144 through 149 each govern a specific situation that arises somewhere within that sequence — contradiction, leading questions, character, and the boundaries of what a witness can be asked. None of those specific rules would make sense without the framework this section provides.
