Oral Evidence vs Documentary Evidence under the Bharatiya Sakshya Adhiniyam, 2023: The Three Rules and Which Prevails

Section 2(1)(e) recognises only two kinds of evidence, and the relationship between them is governed by three separate sets of provisions that answer three different questions. Confusing them produces most of the argument in this area. Section 54 says what may be proved orally. Sections 56 to 60 say how the contents of a document are proved. Sections 94 to 103 say that where a transaction has been reduced to writing, the writing is the only evidence of its terms.

1. The Two Kinds

The definition is exhaustive of the categories and open as to their content. Everything a court receives as evidence is either the statement of a witness or a document produced for inspection, and the Adhiniyam has extended both limbs to their electronic equivalents — statements given electronically on the oral side, and electronic and digital records on the documentary side.

2. The Three Rules

The three operate in sequence and address different objections. A party met with the complaint that his oral evidence is inadmissible should identify which of the three is being invoked, because the answer differs in each case and an answer directed at the wrong rule is no answer at all.

3. The First Rule — Section 54

The section is enabling. Oral evidence is the ordinary means of proving anything, and the single carve-out is the contents of documents and electronic records.

The carve-out is narrower than it appears, and the distinction that matters is between the contents of a document and facts about the document. Contents must be proved under Sections 56 to 60. Everything else may be proved orally.

4. The Second Rule — Proof of Contents

Where the contents of a document are to be proved, Sections 56 to 60 supply the machinery, and they give effect to the best evidence rule.

The principle is that the document itself is the best proof of what it says. A witness recounting the terms of a deed from memory substitutes a fallible account for an exact record, and where the record can be produced there is no reason to accept the account.

Primary evidence under Section 57 is the document itself produced for inspection, together with the electronic outputs the Explanations to that section deem to be primary. Secondary evidence under Section 58 is evidence of the contents given otherwise, and it is admissible only in the circumstances enumerated in Section 60 — where the original is with the opposite party or a person out of reach and is not produced after notice, where its contents are admitted in writing, where it is lost or destroyed, where it is not easily movable, where it is a public document, where a certified copy is permitted by law, and where the originals consist of numerous accounts that cannot conveniently be examined in court.

5. The Third Rule — Exclusion of Oral by Documentary Evidence

Sections 94 to 103 address a different question altogether. They are not about how contents are proved; they assume the document is before the court and ask whether oral evidence may be given to add to, vary or contradict its terms.

Section 95 carries the principle further: where the terms have been proved by the document, no evidence of any oral agreement or statement shall be admitted as between the parties, for the purpose of contradicting, varying, adding to or subtracting from its terms.

The rationale is the certainty of written transactions. Parties who reduce their bargain to writing do so precisely so that the writing shall settle what was agreed, and permitting either of them to say afterwards that something else was agreed would destroy the point of the exercise.

5.1 The provisos

Section 95 carries a series of provisos which are of great practical importance and which are what make the section workable. Oral evidence is admissible to prove, among other things —

• any fact which would invalidate the document, such as fraud, intimidation, illegality, want or failure of consideration, or a mistake in fact or law;
• the existence of a separate oral agreement on a matter on which the document is silent, and which is not inconsistent with its terms, regard being had to the degree of formality of the document;
• the existence of a separate oral agreement constituting a condition precedent to the attaching of any obligation under the document;
• the existence of a distinct subsequent oral agreement to rescind or modify the contract, except where the contract is required by law to be in writing or has been registered;
• any usage or custom by which incidents not expressly mentioned are usually annexed to contracts of that description, provided the annexing would not be repugnant to the express terms;
• any fact showing in what manner the language of the document relates to existing facts.

6. Which Prevails Where They Conflict

Where oral testimony and a document contradict one another, the answer depends on what the conflict is about.

Where the conflict is about the terms of a written transaction, the document prevails and the oral evidence is not merely outweighed but excluded, subject to the provisos. This is not a question of weight at all; Section 95 removes the oral evidence from consideration.

Where the conflict is about a fact outside the document, both are evidence and the court weighs them. A witness who says a payment was made on a particular date, contradicted by an entry in a register, is not excluded by any rule; the court decides which to believe, and in doing so will ordinarily attach considerable weight to a contemporaneous record made without reference to any dispute.

Where the conflict is between a document and the account of how it came into existence, the oral evidence is admissible under the provisos to Section 95 — fraud, want of consideration, a condition precedent — and the question is again one of weight.

As a general matter of assessment, courts prefer a contemporaneous document to recollection, and the reasons are the ones behind the best evidence rule: a document does not forget, does not reconstruct, and was ordinarily made before anyone had a reason to shade the account. But this is a working preference and not a rule, and clear oral evidence may displace a document whose provenance or accuracy is in doubt.

7. The Comparison

8. Electronic Records

Electronic records sit on the documentary side but require a further step, and the two questions must be kept apart.

Relevance and content are governed by the ordinary provisions. An electronic record is a document under Section 2(1)(d), and a statement in it is subject to the same rules about hearsay and admissions as a statement in a letter.

Proof is governed by Sections 57, 61 and 63. The Explanations to Section 57 deem specified electronic outputs to be primary evidence — among them a record produced from proper custody unless disputed, and each of several files where a record is stored simultaneously or sequentially. Section 61 provides that admissibility shall not be denied merely because a record is electronic. Where the output tendered does not fall within the Explanations, it is secondary evidence and the certificate prescribed by the Schedule to Section 63(4) is required, with the hash value in Part A and the expert declaration in Part B.

The practical consequence is that the familiar question — is this primary or secondary evidence — has a different answer for electronic records than for paper, and a party who assumes that a printout must be secondary evidence may be requiring a certificate he does not need, while a party who assumes it must be primary may be tendering a record that cannot be received.

9. The Position Stated Shortly

1. Three separate rules govern the relationship, and they answer three different questions.
2. Section 54 permits every fact to be proved orally except the contents of documents and electronic records, and the carve-out is confined to contents.
3. Facts about a document may always be proved orally — its existence, execution, delivery, condition, loss or destruction.
4. Sections 56 to 60 give effect to the best evidence rule. Primary evidence is required except in the cases enumerated in Section 60, and a foundation must be laid before secondary evidence is received.
5. Sections 94 to 103 exclude oral evidence of the terms of a written transaction, and this is exclusion rather than a question of weight.
6. The provisos to Section 95 are what make the rule workable, admitting evidence of fraud, want of consideration, a condition precedent, a separate collateral agreement, a subsequent modification, and usage.
7. The exclusion operates only between the parties. A stranger to the document is not bound by it.
8. Electronic records require a further step, and whether a given output is primary or secondary is answered by the Explanations to Section 57 rather than by intuition.
