Exclusion of Oral Evidence by Documentary Evidence under Sections 94 to 103 of the Bharatiya Sakshya Adhiniyam, 2023

When parties reduce a bargain to writing they do so precisely so that the writing shall settle what was agreed. Sections 94 and 95 give effect to that intention by shutting out oral evidence of the terms — and then six provisos rescue the rule from the absurdity it would otherwise produce. The remaining eight sections deal with a different problem: what a court may hear when the document, though conclusive as to its terms, does not clearly say what those terms mean.

1. The Chapter

The chapter divides cleanly into two parts. Sections 94 and 95 contain the exclusionary rule and its exceptions. Sections 96 to 101 deal with ambiguity and are best understood as a single connected scheme. Sections 102 and 103 are saving provisions.

2. Section 94 — The Document Is the Evidence of Its Terms

Section 94 is an application of the best evidence rule to transactions. Where the terms have been reduced to writing, the writing is the only evidence of them, and a witness may not be called to say what the terms were.

Two situations are covered and they should be distinguished. The first is where the parties chose to reduce the terms to writing. The second is where the matter is required by law to be in writing — a transfer of immovable property above the statutory value, a mortgage, a will. In the second class the rule operates whether or not the parties intended the document to be exclusive, because the law has made it so.

3. Section 95 — No Oral Agreement to Vary

Section 94 governs how the terms are proved. Section 95 governs what may be said about them once proved. The two operate in sequence and are frequently cited together as though they were one rule.

Two limitations are built into the section and both are important.

It operates only between the parties. The words are 'as between the parties to any such instrument or their representatives in interest'. A stranger to the document is not bound by the rule and may lead oral evidence about the transaction freely. This is why a third party challenging a sale as sham or benami is not met by Section 95, while a party to the sale attempting the same argument must find a proviso.

It bars only evidence of an oral agreement or statement offered to contradict, vary, add to or subtract from the terms. Evidence offered for some other purpose — to establish a collateral fact, to explain conduct, to show what was done under the document — is untouched.

4. The Six Provisos

Without the provisos the rule would be intolerable, because it would protect a document procured by fraud as firmly as one honestly made. They are the most practically important part of the chapter.

Proviso 4 contains the exception most often overlooked. A subsequent oral agreement to rescind or modify is admissible — except where the contract is required by law to be in writing, or has been registered. A registered sale deed, a registered lease, a mortgage: none of these can be orally modified, and evidence of an oral modification is inadmissible however clearly it is proved.

5. Sections 96 to 101 — The Ambiguity Scheme

Six sections deal with what a court may hear when the terms are settled but their application is not. They are best read together, because the distinction that runs through them is a single one: between an ambiguity on the face of the document and one that appears only when the document is applied to facts.

5.1 Section 96 — Patent ambiguity

Where the language of a document is on its face ambiguous or defective, no evidence may be given of facts which would show its meaning or supply its defects.

The reason is that the court is being asked not to construe a document but to write one. Where a blank has been left, or the words are meaningless, there is nothing to construe, and admitting evidence of what the parties meant would be to make an agreement for them.

5.2 Section 97 — Plain language applying accurately

Where the language of a document is plain in itself and applies accurately to existing facts, evidence may not be given to show that it was not meant to apply to such facts.

This is the counterpart of Section 96 at the other end. Where the words are clear and fit the facts exactly, there is no room for construction and no room for evidence. A party who says the document means something other than what it plainly says is contradicting it, and Section 95 would exclude him in any event.

5.3 Sections 98 to 101 — Latent ambiguity

The remaining four sections admit evidence where the ambiguity emerges only on application, and each addresses a distinct situation.

Section 98 — where the language is plain in itself but unmeaning in reference to existing facts, evidence may be given to show that it was used in a peculiar sense.

Section 99 — where the language applies partly to one set of existing facts and partly to another, but the whole of it does not apply correctly to either, evidence may be given to show to which of the two it was meant to apply. In the statutory arrangement this is the provision addressing language capable of applying to one only of several persons, and evidence may be given of facts showing which was intended.

Section 100 — where the language applies to one of two sets of facts, to neither of which the whole correctly applies, evidence may be given to show to which it was meant to apply.

Section 101 — evidence may be given to show the meaning of illegible or not commonly intelligible characters, of foreign, obsolete, technical, local and provincial expressions, of abbreviations, and of words used in a peculiar sense.

Section 101 is the most used of the four and is the route by which trade terms, local usages and technical vocabulary are explained. It connects with Section 43, which makes relevant the opinion of persons having special means of knowledge as to the meaning of words used in particular districts or by particular classes of people.

6. Sections 102 and 103 — The Savings

Section 102 provides that persons who are not parties to a document, or their representatives in interest, may give evidence of any facts tending to show a contemporaneous agreement varying the terms of the document.

The section makes express what Section 95 implies. The exclusionary rule binds the parties and their representatives; a stranger may prove a contemporaneous agreement varying the terms, and the document is not conclusive against him. This is the statutory basis of a great deal of litigation in which a third party asserts that a recorded transaction was not what it appeared to be.

Section 103 saves the provisions of the Indian Succession Act, 1925 relating to wills. Nothing in this chapter affects the construction of wills under that Act, which contains its own body of rules about the admission of extrinsic evidence to explain testamentary language. The saving reflects the different footing on which wills stand throughout the law of evidence: the maker is dead, and the rules that govern a bargain between living parties are not appropriate to an instrument nobody can be asked about.

7. The Chapter in Its Place

Three distinct rules govern the relationship between oral and documentary evidence, and identifying which is being invoked is the first step in meeting any objection.

A party met with an objection should identify which rule is being relied upon, because the answers are entirely different. If the complaint is that he is proving the contents of a writing, the answer may be that secondary evidence is permissible under Section 60. If the complaint is that he is varying the terms of a written contract, the answer must be found in a proviso to Section 95. If the complaint is that his witness did not perceive the fact, it is Section 55 and there is no answer except an exception to the hearsay rule.

8. Practical Points

1. Ask whether the evidence goes to the terms. Section 95 excludes evidence of the terms; it does not touch evidence about execution, delivery, circumstances or conduct.
2. Ask whether the party is a stranger. Section 95 binds only the parties and their representatives; Section 102 expressly permits a stranger to prove a contemporaneous varying agreement.
3. Plead the proviso relied upon. Fraud, want of consideration, a condition precedent and a collateral agreement should each be pleaded specifically, since evidence on an unpleaded case will be objected to.
4. Check proviso 4 against registration. A subsequent oral modification is inadmissible where the instrument is registered or required by law to be in writing.
5. For a collateral oral agreement, address the formality of the document, because proviso 2 directs the court to have regard to it.
6. Classify the ambiguity before arguing about it. Patent ambiguity excludes evidence under Section 96; latent ambiguity admits it under Sections 98 to 101.
7. For trade or local terms, use Section 101 with Section 43, which admits the opinion of persons having special means of knowledge.
8. For wills, remember Section 103 — the Indian Succession Act, 1925 governs and this chapter does not.

9. The Position Stated Shortly

1. Section 94 makes the document the only evidence of its terms, where the terms have been reduced to writing or the law requires writing.
2. Section 95 excludes oral evidence to contradict, vary, add to or subtract from the terms, once proved.
3. The rule binds only the parties and their representatives. A stranger is free, and Section 102 says so expressly.
4. Six provisos make the rule workable — invalidity, a collateral agreement on a silent matter, a condition precedent, a subsequent rescission or modification, usage or custom, and the relation of the language to existing facts.
5. Proviso 4 does not apply to registered instruments or to contracts required by law to be in writing.
6. Patent ambiguity excludes evidence; latent ambiguity admits it. Section 96 on one side, Sections 98 to 101 on the other.
7. Section 97 shuts out evidence where the language is plain and fits the facts exactly.
8. Section 103 saves the law relating to wills, which is governed by the Indian Succession Act, 1925.
