Evidence Law: Indian Evidence Act, 1872 / Bharatiya Sakshya Adhiniyam, 2023 (BSA)

Audio and Video Recordings as Evidence

Audio and Video Recordings as Evidence under the Bharatiya Sakshya Adhiniyam, 2023: The Conditions in Ram Singh, Voice Identification and Proof

Recordings of conversations have been received in Indian courts since the 1960s, and the conditions on which they are received were settled long before the law of electronic evidence existed. Those conditions have not been displaced. A recording tendered today must satisfy both the old judicial requirements — voice identification, accuracy, absence of tampering, safe custody, audibility — and the statutory requirements of Sections 57, 61 and 63. Satisfying one and not the other is of no use at all.

1. A Recording Is a Document

A recording is matter recorded on a substance by means capable of recording it, and it is a document within Section 2(1)(d). The illustrations to that definition name voice mail messages stored on digital devices expressly, and an audio or video file falls within 'electronic and digital records' in any event.

Two consequences follow that are easily overlooked. A recording is proved as a document, not by calling the person who made it and asking what was said — his testimony is evidence about the recording, and the recording is the evidence of the conversation. And the whole of Part III applies, including the rules about primary and secondary evidence and about how much of a record must be produced.

2. The Foundational Decisions

Three decisions established the position and remain the starting point.

📖 Yusufalli Esmail Nagree v. State of Maharashtra, AIR 1968 SC 147

Held: A tape recording of a conversation is admissible in evidence. The process of tape recording offers an accurate method of storing and later reproducing sounds, and the recording is a document within the meaning of the Act. Where a conversation was recorded without the knowledge of one of the participants, the recording does not offend Article 20(3), because the accused was not compelled to speak — he spoke of his own volition, and there was no compulsion to be a witness against himself. The recording of a conversation forming part of the transaction is relevant as res gestae.

Ratio: Recordings are admissible documents; a surreptitious recording does not offend the protection against self-incrimination, because no compulsion is involved.

📖 R.M. Malkani v. State of Maharashtra, (1973) 1 SCC 471

Held: A contemporaneous tape record of a relevant conversation is a relevant fact and is admissible under the provision corresponding to Section 4 of the Adhiniyam. It is res gestae, it is comparable to a photograph of a relevant incident, and it is therefore a relevant fact. The Court held that the recording was admissible provided the conversation is relevant, the voice is identified, and the accuracy of the recording is proved by eliminating the possibility of erasure. It further held that the protection against self-incrimination was not attracted, there being no compulsion.

Ratio: A contemporaneous recording is relevant as part of the transaction, on the same footing as a photograph of the incident.

📖 Ram Singh v. Col. Ram Singh, 1985 Supp SCC 611

Held: The Court set out the conditions governing the admissibility of tape-recorded evidence. (i) The voice of the speaker must be duly identified by the maker of the record or by others who recognise his voice; where the voice is denied by the maker, it may be proved by comparison. (ii) The accuracy of the tape-recorded statement must be proved by the maker of the record by satisfactory evidence, direct or circumstantial. (iii) Every possibility of tampering with or erasure of a part of the record must be ruled out, and the burden lies on the party tendering it. (iv) The statement must be relevant according to the rules of evidence. (v) The recording must be carefully sealed and kept in safe or official custody. (vi) The voice must be clearly audible and not lost or distorted by other sounds or disturbances.

Ratio: The leading statement of the conditions, applied to recordings of every kind and undisplaced by the statutory provisions on electronic evidence.

3. The Six Conditions Examined

3.1 Identification of the voice

The recording establishes that words were spoken; it does not establish by whom. Identification proceeds by three routes and they are not equally strong.

Recognition by a person familiar with the voice is the ordinary route. A witness who knows the speaker deposes that the voice is his, and is cross-examined on the basis and extent of his familiarity and on the quality of the recording.

Admission by the speaker is the strongest, and is often obtained in cross-examination where the content is not damaging in itself.

Expert comparison with a voice sample is available under Section 39(1), whose residuary words now accommodate voice analysis without any argument about whether it is a 'science'. The court's power to compel a sample is settled.

📖 Ritesh Sinha v. State of Uttar Pradesh, (2019) 8 SCC 1

Held: A three-Judge Bench held that a Judicial Magistrate may order a person to give a voice sample for the purposes of investigation, notwithstanding the absence of an express statutory provision, in exercise of a power to be inferred from the scheme of the criminal procedure legislation. Compelling a voice sample does not violate Article 20(3), since a voice sample, like a specimen signature or a thumb impression, is material for comparison and does not convey any personal knowledge relating to the offence. The position follows from State of Bombay v. Kathi Kalu Oghad, AIR 1961 SC 1808.

Ratio: A voice sample is identificatory rather than testimonial, and may be compelled.

3.2 Accuracy

The maker of the recording must prove that it accurately reproduces the conversation. What is required is evidence of who made the recording, with what device, when, where, and in what circumstances, and that the recording covers the whole of the relevant conversation.

A recording produced by somebody who cannot say how it was made, or who was not present when it was made, has not been proved accurate, and the condition is not satisfied by the recording sounding plausible.

3.3 Absence of tampering

Ram Singh places the burden on the party tendering the recording to rule out the possibility of tampering or erasure. This is a demanding requirement and it is the condition that most often fails.

Audio and video are edited without difficulty and without visible trace, and a party cannot discharge the burden simply by asserting that no editing occurred. What discharges it is preservation of the original recording in its original device or format, a hash computed at the earliest moment, sealing and custody, and where the point is contested, expert examination of the file for discontinuities, splices, encoding inconsistencies and metadata anomalies.

3.4 Relevance

The recording must be relevant under the ordinary heads. Most commonly it is relevant as part of the transaction under Section 4, on the reasoning in R.M. Malkani; as an admission under Section 15 where the speaker is a party; as conduct under Section 6(2); or as showing a state of mind under Section 12.

Where the speaker is not a party and the recording is offered to prove the truth of what he said, it is hearsay, and proving the recording under Section 63 does not make the assertion true.

3.5 Sealing and custody

The recording must be sealed and kept in safe or official custody. This requirement predates the modern chain-of-custody discipline and expresses the same idea: the court must be able to see that what it is hearing is what was recorded.

3.6 Audibility

The voice must be clearly audible and not lost or distorted. A recording in which the material words cannot be heard proves nothing, and a transcript prepared by an interested party does not cure it — the transcript is an aid to listening, not a substitute for it, and where the parties differ about what is audible the court must listen for itself.

4. The Standard Applied

📖 Tukaram S. Dighole v. Manikrao Shivaji Kokate, (2010) 4 SCC 329

Held: Electronic recordings are prone to tampering, alteration, transposition and excision, and the court must therefore be satisfied beyond reasonable doubt that the record has not been tampered with. The standard of proof about the authenticity and accuracy of such evidence has to be more stringent than in the case of documentary evidence, and the party tendering the recording must establish its genuineness by cogent evidence. A recording produced without proof of the source, the manner of recording and the custody of the record cannot be acted upon.

Ratio: The standard of proof for the authenticity of a recording is more stringent than for ordinary documentary evidence, precisely because of the ease of manipulation.

This decision is the modern statement of why the Ram Singh conditions are applied strictly. The reasoning has, if anything, strengthened: editing tools that once required equipment and skill are now available to anybody, and the absence of visible signs of editing establishes nothing.

5. The Statutory Layer

The judicial conditions govern weight and authenticity. The statutory provisions govern admissibility, and both must be satisfied.

Primary or secondary? The Explanations to Section 57 apply. Explanation 3 makes each of several files storing a record primary evidence. Explanation 4 makes a record from proper custody primary evidence unless disputed — which, in a case about a recording, it invariably will be. Explanation 5 is directly in point where a video recording was simultaneously stored and transmitted or broadcast, and it makes each stored recording primary evidence without the qualification that weakens Explanation 4.

Where the certificate is required, the four conditions in Section 63(2) must be satisfied and the certificate under Section 63(4) furnished in the form of the Schedule, with the hash value in Part A and an expert declaration in Part B.

⚠ The hash and the anti-tampering condition are the same requirement

Ram Singh requires the party to rule out tampering. The Schedule requires disclosure of a hash value. These are not two burdens but one, approached from different directions — and the hash is by far the better answer, because it converts an assertion that the recording is unaltered into a verifiable proposition. A digest computed when the recording was preserved, recorded contemporaneously, and matching the file produced in court discharges the Ram Singh burden more convincingly than any amount of oral assurance.

6. Transcripts

A transcript is almost always produced with a recording, and its status should be clear.

A transcript is not the evidence. The recording is the evidence, and the transcript is an aid to following it. It is prepared by somebody, and that somebody's accuracy, competence and impartiality are all open to question.

Three points follow. The person who prepared the transcript should be identified and, where it is contested, examined. Where the parties differ about a passage, the court must listen to the recording and form its own view. And where the conversation is in a language the court does not follow, a translation is a further layer requiring its own proof — the translator being, in effect, an expert whose competence must be established.

7. Completeness

Section 33, BSA

When any statement of which evidence is given forms part of a longer statement, or of a conversation, or part of an isolated document, or is contained in part of an electronic record, evidence shall be given of so much and no more as the Court considers necessary in that particular case to the full understanding of the nature and effect of the statement, and of the circumstances under which it was made.

A recording of a conversation engages the section on two footings, being both a conversation and an electronic record. The requirement is the same as with any exchange: enough must be produced for the court to understand what was said and the circumstances in which it was said.

A party producing an extract from a longer recording, or a recording that begins part-way through a conversation, should expect to be asked for the rest. Where it is withheld, Illustration (g) to Section 119 permits the presumption that what is withheld would have been unfavourable — and in the case of a recording the inference is a natural one, since a party who recorded a conversation ordinarily has the whole of it.

8. Recordings Made Without Consent

A recording made without the knowledge of one participant raises three questions, and the answers are settled.

Is it admissible? Yes. Yusufalli Nagree and R.M. Malkani both concerned surreptitious recordings and both held them admissible. The general Indian position, established in Pooran Mal v. Director of Inspection (Investigation), (1974) 1 SCC 345, is that the test of admissibility is relevancy, and evidence is not excluded because of the manner in which it was obtained unless a statute so provides.

Does it offend Article 20(3)? No. The protection is against being compelled to be a witness against oneself. A person who speaks of his own volition, unaware that he is being recorded, is not compelled, and both decisions so held.

Is it lawful? That is a different question from admissibility. Interception of communications is regulated by the Information Technology Act, 2000 and by the telegraph legislation, and unauthorised interception may be an offence. A recording obtained unlawfully may nevertheless be admissible on the Pooran Mal principle, while exposing the person who made it to consequences — and the circumstances in which it was obtained remain a legitimate subject of comment on its weight.

⚠ Admissibility and propriety are different questions

A party producing a surreptitious recording should expect the court to receive it and then to ask why it was made, when, and by whom. A recording made by a person who anticipated litigation and set out to manufacture evidence is admissible and may be worth very little, because the conversation may have been steered. The circumstances of making are always relevant to weight even where they are irrelevant to admissibility.

9. A Practical Checklist

  1. Preserve the original device or file, not a copy shared through a messaging application, which re-encodes and strips metadata.
  2. Compute a hash at the moment of preservation and record it contemporaneously.
  3. Seal and keep the record in safe custody, as Ram Singh requires.
  4. Identify the maker and be ready to prove when, where, with what device and in what circumstances the recording was made.
  5. Plan the voice identification — a witness familiar with the voice, an admission, or an expert comparison with a sample.
  6. Produce the whole recording, not an extract, because Section 33 requires it and withholding invites an adverse inference.
  7. Prepare the transcript carefully, identify who made it, and treat it as an aid rather than as the evidence.
  8. Obtain the certificate under Section 63(4), and consider whether Explanation 5 to Section 57 applies where the recording was simultaneously stored and transmitted.

10. The Position Stated Shortly

  1. A recording is a document and is proved as one, not by the testimony of the person who made it.
  2. Recordings have been admissible since Yusufalli Nagree, and a contemporaneous recording is relevant as part of the transaction — R.M. Malkani.
  3. The six conditions govern — laid down in Ram Singh — voice identification, accuracy, absence of tampering, relevance, sealing and custody, and audibility.
  4. The burden of ruling out tampering lies on the party tendering, and the standard of proof as to authenticity is more stringent than for ordinary documents — Tukaram Dighole.
  5. The statutory layer applies as well. Explanations 4 and 5 to Section 57, and where they do not apply, Section 63 and the certificate.
  6. The hash value is the modern answer to the anti-tampering condition, and it is far stronger than oral assurance.
  7. A transcript is an aid, not the evidence, and where the parties differ the court must listen for itself.
  8. A surreptitious recording is admissible and does not offend Article 20(3), though the circumstances of making bear on its weight.
