Explain the scope of examination-in-chief, cross-examination and re-examination under the Indian Evidence Act. State briefly their objects. What documents may be used by a witness to refresh his memory? In the Indian Evidence Act what is meant by 'refreshing memory'?

The law of evidence is, in a very real sense, the law of human memory and human honesty. Every rule in Chapter X of the Indian Evidence Act, 1872 — now re-enacted in Chapter X of the Bharatiya Sakshya Adhiniyam, 2023 — is designed to ensure that the court gets as close to the truth as the human condition will allow. At the heart of this chapter lies the structured examination of witnesses: the examination-in-chief, the cross-examination, and the re-examination. And woven into the fabric of this structure is the doctrine of refreshing memory — a recognition that the human mind forgets, and that a just system must provide for that frailty.

The Statutory Foundation

Section 137 of the IEA (corresponding to Section 142 of the BSA) defines the three kinds of examination with admirable clarity. The examination of a witness by the party who calls him is his examination-in-chief. The examination by the adverse party is his cross-examination. And the examination by the party who called him, subsequent to the cross-examination, is his re-examination. Section 138 of the IEA (Section 143 of the BSA) lays down the order in which these examinations must proceed, and the scope of each.

The structure is sequential and interdependent. Witnesses shall be first examined-in-chief, then — if the adverse party so desires — cross-examined, and then — if the party calling him so desires — re-examined. The word "desires" in the statute is significant: cross-examination and re-examination are rights, not obligations. An adverse party may choose not to cross-examine a witness if the testimony given in chief does not injure its case, or is beyond challenge. But once the right is declined, it cannot ordinarily be reclaimed.

Examination-in-Chief: Laying the Foundation

The examination-in-chief is the real curtain-raiser of the forensic battle. It is through this examination that the party calling the witness unfolds his case — telling his story in a coherent, chronological, and persuasive manner. Section 138 of the IEA (Section 143 of the BSA) requires that the examination-in-chief must relate to relevant facts. It cannot range over matters that are irrelevant to the issues before the court.

The cardinal restriction that governs the examination-in-chief is the rule against leading questions. Section 142 of the IEA (Section 146 of the BSA) states that leading questions — that is, questions which suggest to the witness the answer which the questioner wishes or expects to receive — must not, if objected to, be asked in examination-in-chief or re-examination, except with the court's permission. The reason for this prohibition is deeply practical. The witness is presumed to be favourably disposed towards the party who calls him, and if leading questions were freely permitted, the advocate could simply put the entire story into the witness's mouth and reduce the examination to a series of affirmative nods. The court would then receive, not the witness's genuine recollection, but the advocate's scripted version of events. This is precisely what the law will not countenance.

The court, however, has discretion to permit leading questions as to matters which are introductory, undisputed, or already sufficiently proved. For questions of a routine or non-controversial character — the witness's name, address, occupation — there is no need to insist upon the non-leading form, and doing so would be a needless waste of the court's time.

Once examination-in-chief is conducted, the statement becomes part of the record. It is evidence in the true sense of the word. In Hardeep Singh v. State of Punjab (AIR 2014 SC 1400), the Supreme Court held that examination-in-chief untested by cross-examination is, undoubtedly in itself, evidence. However, as the same court has repeatedly observed, the statements made in examination-in-chief lose much of their credibility and weight unless they are put into the crucible of cross-examination and emerge unscathed from the test.

Cross-Examination: The Greatest Legal Engine

John Henry Wigmore, the pre-eminent American evidence scholar, called cross-examination "the greatest legal engine ever invented for the discovery of truth." India's courts have enthusiastically adopted this view. Cross-examination is the most powerful and the most feared of the three stages of examination — and rightly so, for it is the moment when the story told in examination-in-chief is put to the test.

Section 138 of the IEA (Section 143 of the BSA) states that the examination and the cross-examination must relate to relevant facts, but — and this is the critical distinction — the cross-examination need not be confined to the facts to which the witness testified on his examination-in-chief. This latitude is necessary for the very purposes which cross-examination is designed to serve.

Objects of Cross-Examination

The objects of cross-examination are three-fold, and have been stated with remarkable precision by the courts over the years. In Anita Sharma v. New India Assurance Co. Ltd. (2021 1 SCC 171), the Supreme Court enumerated them:

1. To destroy or weaken the evidentiary value of the witness of the adversary

2. To elicit from the adverse witness facts favourable to the cross-examiner's client

3. To show that the witness is unworthy of belief by impeaching his credit

4. To test his veracity — by probing the sources of his knowledge, his opportunity to observe, his capacity to remember

5. To discover who he is and what his position in life is

6. To shake his credit by injuring his character

These objects explain why cross-examination is given the wide latitude that Section 138 of the IEA and Section 143 of the BSA confer upon it. If cross-examination were confined strictly to the facts deposed in chief, an experienced advocate could conduct the examination-in-chief in such a manner as to shut out an entire category of relevant facts, leaving the cross-examiner with no room to manoeuvre. The legislature has wisely prevented this by allowing cross-examination to extend to the whole case.

Scope and Leading Questions

Unlike examination-in-chief, leading questions may be freely asked in cross-examination. Section 143 of the IEA (Section 146(4) of the BSA) is unambiguous on this point. The reason is equally clear: the cross-examiner is dealing with an adverse witness, and there is no risk of his tutoring or coaching that witness. The element of dexterous surprise — which Wigmore regarded as the very soul of effective cross-examination — can only be preserved if the advocate can put pointed, direct, and suggestive questions.

In Vinod Kumar v. State of Punjab (2015 3 SCC 220), the Supreme Court emphasised that it is imperative, if examination-in-chief is over, that cross-examination should be completed on the same day. The inordinate deferral of cross-examination — in that case, by over a year and eight months — was described by the court as "an anathema to the concept of proper and fair trial."

Limits on Cross-Examination

The right of cross-examination, though wide, is not without its governors. Section 146 of the IEA (Section 149 of the BSA) permits questions that test veracity, discover the witness's position in life, or shake his credit by injuring his character — even if the answers might incriminate the witness. But Section 148 of the IEA (Section 151 of the BSA) requires the court to decide whether questions going only to credit should be compelled, and to weigh their propriety. Section 149 of the IEA (Section 152 of the BSA) provides that no question imputing a charge against a witness shall be asked without reasonable grounds for believing the imputation to be well-founded. Sections 151 and 152 of the IEA (Sections 154 and 155 of the BSA) require the court to forbid questions that are indecent, scandalous, or intended to insult or annoy the witness.

The proviso to Section 146 of the IEA (Section 149 of the BSA) — inserted by the Criminal Law Amendment Act, 2013 and carried forward in the BSA with reference to offences under the Bharatiya Nyaya Sanhita — specifically provides that in prosecutions for rape and allied sexual offences, questions as to the victim's general immoral character or previous sexual experience shall not be permitted in cross-examination for proving consent or the quality of consent. This proviso is a landmark of legislative wisdom and judicial sensitivity.

One further discipline governs cross-examination: the rule of confrontation. A witness whose credibility is to be challenged by a prior inconsistent statement must be confronted with it, under Section 145 of the IEA (Section 148 of the BSA), before it can be used against him. This is fair play, not a technicality — the witness must be given an opportunity to explain the inconsistency.

The Rule of Non-Examination as Acceptance

A critically important consequence follows from the failure to cross-examine. The Supreme Court has held, in a consistent line of authority, that if the relevant facts stated in examination-in-chief are not challenged in cross-examination, they shall be deemed to be admitted. In Sarwan Singh v. State of Punjab (2003 1 SCC 240), the court stated that where the opponent has declined to avail himself of the opportunity to put his case in cross-examination, it must follow that the evidence tendered on that issue ought to be accepted. The fact not put to a witness in cross-examination is treated as accepted.

Re-Examination: Repairing the Damage

The re-examination is the final opportunity afforded to the party who called the witness to repair any damage done in cross-examination. Section 138 of the IEA (Section 143 of the BSA) provides that re-examination shall be directed to the explanation of matters referred to in cross-examination. If new matter is introduced in re-examination — with the permission of the court — the adverse party gets the right to further cross-examine upon that new matter.

Object and Scope

The object of re-examination is to fill in the lacunae or explain the inconsistencies which the cross-examination has exposed. It is not an opportunity to supplement the examination-in-chief with entirely new testimony that has no connection with what was discussed in cross-examination. The Supreme Court stated this with clarity in Pannayar v. State of Tamil Nadu (AIR 2010 SC 85): there is an erroneous impression that re-examination should be confined to the clarification of ambiguities alone. In fact, if the party who called the witness feels that explanation is required for any matter referred to in cross-examination, he has the liberty to put any question in re-examination to get that explanation. The public prosecutor should formulate his questions for that purpose, and the court should be liberal in granting permission. However, totally new facts which have no concern with the cross-examination cannot be introduced in re-examination.

Like the examination-in-chief, re-examination also prohibits leading questions, subject to the court's permission. It partakes of the character of examination-in-chief — the witness is again being examined by the party who called him, and the presumption of favourability re-emerges.

A Comparative Overview of the Three Stages

Refreshing Memory: The Doctrine in Its Entirety

It would be unrealistic to expect that a witness who observed a transaction months or years before the trial will carry every detail alive in his mind. The law of evidence has long recognised that the memory of an honest witness can fail without any dishonest intent. The doctrine of refreshing memory — governed by Sections 159, 160, and 161 of the IEA (Sections 162, 163, and 164 of the BSA) — is the legal mechanism that addresses this human frailty.

What is Refreshing Memory?

Refreshing memory means that a witness, while under examination in court, may refer to a document to revive or jog his recollection before giving oral testimony about the facts recorded in that document. The critical point is that the witness is not reading from the document as a substitute for oral testimony — he is using the document as a trigger to assist the process of recollection, so that he can then speak from his own revived memory. This distinction is fundamental. The document is an aid to the memory, not a replacement for it.

Section 159 of the IEA (Section 162 of the BSA): The Core Provision

Section 159 of the IEA (Section 162 of the BSA) lays down the conditions under which a witness may refresh his memory by reference to a writing. The provision operates in three distinct situations:

First — A witness may refresh his memory by referring to any writing made by himself at the time of the transaction concerning which he is questioned, or so soon afterwards that the court considers it likely that the transaction was at that time fresh in his memory.

Second — A witness may also refer to any such writing made by any other person, and read by the witness within the time aforesaid — provided that when he read it, he knew it to be correct.

Third — an expert may refresh his memory by reference to professional treatises. This is a special dispensation for expert witnesses — a doctor testifying about symptoms, a chemist about a compound, or a ballistics expert about trajectory — who may refer to standard professional texts to anchor their opinion.

The section also permits a witness to refer to a copy of a document to refresh memory, with the court's permission, provided the court is satisfied that there is sufficient reason for the non-production of the original.

The Time Element: "At the Time" or "So Soon Afterwards"

The phrase "so soon afterwards that the court considers it likely that the transaction was at that time fresh in his memory" is a standard of temporal proximity that the courts have applied with good sense. What this means is that the writing need not have been made at the very instant of the transaction — it may have been made a few hours or days later — but the time lapse must be short enough that the court can be satisfied the memory was still fresh when the record was made. A police officer who records a statement the same day he witnesses an event stands on safe ground. A person who makes a note of a complex financial transaction a week later may or may not satisfy the court, depending on the nature of the transaction and the interval.

In Mangat Ram v. Pakhar Singh (AIR 1962 Pun 374), the Punjab High Court held that whether the writing was made at such a time that the transaction was still fresh in the witness's memory is essentially a question of fact, to be decided by the court on the circumstances of each case.

Section 160 of the IEA (Section 163 of the BSA): Testimony Without Specific Recollection

Section 160 of the IEA (Section 163 of the BSA) takes the doctrine a step further. It provides that a witness may testify to facts mentioned in any such document as is mentioned in Section 159, even if he has no specific recollection of the facts themselves, provided he is sure that the facts were correctly recorded in the document.

The illustration to Section 160 captures this with precision: a book-keeper may testify to facts recorded by him in books regularly kept in the course of business, if he knows that the books were correctly kept, although he has forgotten the particular transactions entered.

This is an important provision. It recognises that in the world of modern business and administration, the sheer volume of transactions makes it impossible to retain specific recollection of each one. A person who keeps careful and accurate records may legitimately testify from those records even without independent memory, provided he is able to affirm the correctness of the records themselves. The weight to be attached to such testimony will, of course, be assessed by the court.

Section 161 of the IEA (Section 164 of the BSA): The Adverse Party's Right

The provision for refreshing memory would be incomplete — and potentially dangerous — without a corresponding right in the adverse party to examine the document used. Section 161 of the IEA (Section 164 of the BSA) provides that any writing referred to under Sections 159 and 160 must be produced and shown to the adverse party if he requires it, and the adverse party may, if he pleases, cross-examine the witness thereupon.

This is a rule of fundamental fairness. If a witness refreshes his memory from a document, and the adverse party cannot see that document, the cross-examiner operates in the dark. He cannot tell whether the witness is genuinely refreshing a fading memory or reading a narrative prepared by someone else. The right to inspect and cross-examine on the document is, therefore, essential to the integrity of the process.

In the context of police diaries under Section 172 of the CrPC (now Section 192 of the BNSS, 2023), the law provides a specific application of this principle. Where a police officer refreshes his memory by looking at an entry in the case diary, the accused or his agent is entitled to see that entry and to cross-examine the officer upon it. The diary entry does not become substantive evidence by this process — it remains only the basis of the refreshed testimony.

Documents That May Be Used to Refresh Memory

Drawing together the threads from Section 159 and the judicial decisions, the documents that may be used to refresh memory include:

• A writing made by the witness himself at the time of the transaction or so soon afterwards that the transaction was fresh in his memory — this includes a witness's personal diary, a note made on the spot, a letter written contemporaneously, or a memorandum prepared soon after an event

• A writing made by another person and read by the witness when he knew it to be correct — for example, a statement recorded by an officer from the mouth of a witness, which the witness read and confirmed

• Business records regularly kept in the course of business, where the person keeping the records can affirm their correctness under Section 160

• A copy of a document, with the court's permission, when the original is unavailable for sufficient reason

• Professional treatises, in the case of expert witnesses

What cannot be used to refresh memory is any document that the witness never verified for correctness, or that was made so long after the event that the court cannot be satisfied the memory was fresh at the time of recording.

Refreshing Memory vs. Past Recollection Recorded

There is a distinction that must be carefully observed. The provision under Section 159 — refreshing memory — contemplates a situation where the witness does have some memory of the event, and the document merely revives it. The provision under Section 160 — testimony without specific recollection — addresses the situation where the witness has no independent memory but can affirm the correctness of the document. In the second case, the testimony rests on the document's reliability rather than on revived personal recollection. Both modes are permissible, but they operate on different foundations, and the court must know which of the two it is dealing with when assessing the weight of the testimony.

The Supreme Court, across a broad range of decisions, has consistently held that refreshing memory is a legitimate tool of a fair trial. Its abuse — where a witness effectively reads from a prepared narrative rather than speaking from refreshed recollection — is a matter that the court must guard against by careful observation of the witness's demeanour, the nature of the document, and the manner in which it is being used.
