Section 96 BSA: Exclusion of Evidence to Explain Ambiguous Document

Section 96 BSA bars external evidence to explain or cure ambiguity apparent on the face of a document.

Introduction

Section 96 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA) governs the exclusion of evidence offered to explain or amend an ambiguous document. Where the language of a document is ambiguous or defective on its face, a party cannot ordinarily introduce external evidence to determine what the disputed wording was intended to mean or to fill in defects left in the document.

The provision reflects the distinction between patent ambiguity and latent ambiguity. Patent ambiguity is apparent from the document itself, whereas latent ambiguity arises when apparently clear language is applied to existing facts. Section 96 addresses patent ambiguity; the following provisions of the BSA deal with related rules of documentary interpretation.

Section 96 substantially corresponds to Section 93 of the Indian Evidence Act, 1872. It is important in disputes concerning contracts, deeds, property transactions and other written instruments.

Bare Act: Section 96 of the Bharatiya Sakshya Adhiniyam, 2023

96. Exclusion of evidence to explain or amend ambiguous document.— When the language used in a document is, on its face, ambiguous or defective, evidence may not be given of facts which would show its meaning or supply its defects.

Illustrations

(a) A agrees, in writing, to sell a horse to B for “one lakh rupees or one lakh fifty thousand rupees”. Evidence cannot be given to show which price was to be given.

(b) A deed contains blanks. Evidence cannot be given of facts which would show how they were meant to be filled.

Explanation of Section 96 BSA

1. Meaning of an ambiguous document

A document is ambiguous when its wording does not clearly convey the intended meaning. Under Section 96, the relevant ambiguity must be apparent from the language of the document itself.

For example, if a written agreement states that a horse will be sold for either ₹1,00,000 or ₹1,50,000 without resolving which price applies, the document contains an ambiguity on its face.

A party cannot ordinarily introduce oral testimony or other external evidence merely to establish which of those two prices the parties supposedly intended.

2. What is patent ambiguity?

Patent ambiguity refers to uncertainty that is apparent from reading the document without needing to examine external circumstances.

Examples include:

• A written agreement specifying two alternative prices without identifying the applicable price.
• A deed containing blank spaces where material terms should have been entered.
• A written instrument containing wording so uncertain or defective that its intended meaning cannot be established from the document itself.

Section 96 prevents a party from curing such defects through evidence of what the parties allegedly intended.

3. Why does Section 96 exclude such evidence?

The provision promotes certainty and reliability in documentary transactions. If a party could routinely rely on oral statements to complete missing terms or choose between contradictory expressions, the written instrument would cease to provide a dependable record of the transaction.

The rule also prevents courts from effectively drafting a new agreement for the parties by supplying material terms that the document itself fails to establish.

However, Section 96 should not be read as a universal prohibition on external evidence in every dispute concerning a document. The precise issue is whether the evidence is being offered to cure ambiguity or a defect apparent on the face of the document.

4. Application of Section 96 to contracts

Section 96 may become relevant when a party seeks to enforce a contract whose written terms are inherently uncertain.

Example: A and B sign an agreement stating that A will sell a specified horse to B for either ₹1,00,000 or ₹1,50,000. A later claims that the lower amount was intended, while B claims that the higher amount was agreed.

Under the illustration to Section 96, evidence cannot be introduced merely to select the intended price. The ambiguity appears in the written agreement itself.

The question of whether the agreement is enforceable must also be assessed under the applicable substantive law, including Section 29 of the Indian Contract Act, 1872, where relevant. Section 96 is an evidentiary rule; it does not independently determine every question of contractual validity.

5. Application where a deed contains blanks

The second illustration concerns a deed containing blanks.

Example: A deed purports to transfer property but leaves a material description blank. A party attempts to introduce oral testimony to establish what property was supposed to be inserted in that space.

Section 96 excludes evidence offered to supply the defect in the manner described by the illustration. Whether the document has any other legally effective operation depends on its wording and the applicable law.

A court must distinguish between impermissibly supplying a missing term and admissible evidence relevant to a separate legal issue.

Patent Ambiguity vs Latent Ambiguity

The distinction between patent and latent ambiguity is central to understanding Section 96 BSA.

Basis	Patent ambiguity	Latent ambiguity
Meaning	The uncertainty is apparent from the document itself	The uncertainty emerges when the document is applied to existing facts
Source	Defective, uncertain or contradictory wording	A difficulty in identifying the person, property or subject to which apparently clear words refer
Relevant provisions	Section 96 BSA	Sections 98–100 BSA may be relevant, depending on the type of ambiguity
External evidence	Section 96 bars evidence offered to explain or cure the facial ambiguity	Relevant external evidence may be admissible under the applicable provision
Example	An agreement specifies two alternative prices without identifying the applicable one	A deed refers to a person’s property in a particular city, but the person owns no property there and owns a property in a nearby city

The distinction is not simply whether a document is unclear. The court must examine where the uncertainty originates and what the evidence is intended to establish.

Difference Between Section 96 and Section 97 BSA

Sections 96 and 97 deal with different problems in interpreting documents.

Basis	Section 96 BSA	Section 97 BSA
Subject	Exclusion of evidence to explain or amend an ambiguous document	Exclusion of evidence against the application of a document to existing facts
Nature of language	Ambiguous or defective on its face	Plain in itself and accurately applicable to existing facts
Main rule	External evidence cannot be used to explain the facial ambiguity or supply its defects	Evidence cannot be introduced to show that clear language was not intended to apply to facts it accurately describes
Illustrative situation	A written agreement gives two alternative prices for the same horse	A deed clearly describes an estate that matches the owner’s actual estate, but a party claims it referred to a different property

Section 96 addresses ambiguity in the document’s language. Section 97 addresses an attempt to depart from the application of clear language where it accurately fits the existing facts.

Important Case Laws on Section 96 BSA

The following decisions concern the predecessor provision, Section 93 of the Indian Evidence Act, 1872, or closely related principles of documentary interpretation and contractual certainty. They should not be described as judgments originally decided under Section 96 BSA.

1. Keshavlal Lallubhai Patel v. Lalbhai Trikumlal Mills Ltd., AIR 1958 SC 512

Court: Supreme Court of India

Legal principle: The dispute involved the uncertainty of conditions concerning an extension of time for performance. The Supreme Court considered whether the relevant conditions were sufficiently definite and addressed the principle of contractual certainty under Section 29 of the Indian Contract Act, 1872.

Relevance to Section 96 BSA: The decision is relevant to the broader principle that courts cannot simply resolve material uncertainty by supplying a meaning that the contractual language does not establish. Its central relevance is to contractual certainty; it should not be treated as a decision exclusively interpreting Section 96 BSA.

2. Sachin C. Shah v. Hemant D. Shah & Others, decided on 6 May 2015

Court: Bombay High Court

Case reference: Arbitration Petition Nos. 974 of 2011 and 1069 of 2011.

Legal principle: The dispute concerned a family arrangement recorded in a memorandum of understanding, including questions about blank annexures and whether the document was sufficiently certain to be enforced. The Court discussed the distinction between patent and latent ambiguity and considered the prohibition against using evidence to cure ambiguity apparent on the face of a document.

The Court also examined whether the memorandum itself supplied an agreed basis for preparing the annexures, rather than whether the arbitrator was impermissibly creating contractual terms.

Relevance to Section 96 BSA: The judgment illustrates why courts must distinguish between filling a facially defective document with an intended meaning that it does not contain and resolving disputed matters by applying a basis already established in the document. It is a decision under the former Evidence Act and should be read in the context of its particular facts.

Relationship Between Section 96 BSA and Section 29 of the Indian Contract Act, 1872

Section 96 is concerned with the admissibility of evidence offered to explain or cure facial ambiguity in a document. Section 29 of the Indian Contract Act, 1872 concerns agreements whose meaning is not certain or capable of being made certain.

These provisions address related but distinct questions:

• Section 96 BSA: Can external evidence be admitted to explain or supply a defect apparent on the face of the document?
• Section 29 of the Indian Contract Act, 1872: Is the agreement void because its meaning is uncertain or incapable of being made certain?

A document that contains facial ambiguity does not automatically lead to the same outcome in every case. Its legal effect depends on the nature of the defect, the contractual terms and the applicable substantive law.

Practical Examples of Section 96 BSA

Situation	Application of Section 96
A written sale agreement specifies two different prices without stating which applies	Evidence cannot be introduced merely to select the intended price
A deed contains blanks and a party seeks to establish orally how they were intended to be filled	The illustration excludes evidence offered to supply those defects
A document uses clear wording, but the identity of the property becomes uncertain when applied to external facts	The issue may involve latent ambiguity and a different statutory provision
A party alleges that a document was obtained by fraud	The question is distinct from merely curing a facial ambiguity and must be examined under the applicable rules
A party seeks to enforce an agreement with materially uncertain terms	Section 96 and the applicable substantive law, including Section 29 of the Contract Act where relevant, may need to be considered

These examples are illustrative. The admissibility and legal effect of evidence depend on the document, the purpose for which the evidence is offered and the relevant provisions of law.

What is Section 96 of the Bharatiya Sakshya Adhiniyam, 2023?

Section 96 excludes evidence of facts offered to explain or supply defects where the language of a document is ambiguous or defective on its face.

What is patent ambiguity under Section 96 BSA?

Patent ambiguity is uncertainty apparent from reading the document itself, such as an agreement specifying two alternative prices without identifying which one applies.

Can oral evidence be used to fill blanks in a deed?

Under the illustration to Section 96, evidence cannot be given to establish how blanks in a deed were intended to be filled. The legal effect of the document must be assessed in light of the actual defect and applicable law.

What is the difference between patent and latent ambiguity?

Patent ambiguity appears on the face of a document. Latent ambiguity arises when apparently clear language is applied to existing facts and a difficulty emerges in identifying the intended person, property or subject.

Which section of the Indian Evidence Act corresponds to Section 96 BSA?

Section 96 BSA substantially corresponds to Section 93 of the Indian Evidence Act, 1872.

Which case laws are relevant to Section 96 BSA?

Keshavlal Lallubhai Patel v. Lalbhai Trikumlal Mills Ltd., AIR 1958 SC 512, is relevant to contractual certainty. Sachin C. Shah v. Hemant D. Shah, decided by the Bombay High Court on 6 May 2015, discusses patent and latent ambiguity in documentary interpretation.

Conclusion

Section 96 of the Bharatiya Sakshya Adhiniyam, 2023 prevents parties from using external evidence to explain or repair ambiguity that is apparent from the language of a document itself. The rule promotes certainty in written instruments and prevents courts from supplying missing terms merely on the basis of alleged intentions.

For proper application, the court must distinguish patent ambiguity from latent ambiguity and identify the purpose for which the evidence is offered. Section 96 should also be read alongside the neighbouring provisions governing documentary interpretation and, where contractual uncertainty is involved, the relevant principles of substantive contract law.
