Indian Evidence Law – Bharatiya Sakshya Adhiniyam 2023-Exclusion of Evidence to Explain or Amend an Ambiguous Document [Section 96]

​Meaning and Object
Section 96 deals with cases where a document is ambiguous or defective on the face of it. Such ambiguity is known as patent ambiguity, i.e., an uncertainty that is apparent from the document itself without reference to external facts.
The object of this provision is to maintain the certainty and sanctity of written documents by preventing parties from using oral or extrinsic evidence to correct obvious defects or ambiguities.

Statutory Rule
When the language used in a document is ambiguous or defective on its face,
no evidence may be given of facts which would:

• Explain its meaning, or
• Supply or remove its defects.

Nature of Ambiguity

• The ambiguity must be visible from the document itself.
• It must not require external facts to discover the defect.
• Such ambiguity cannot be cured by oral or extrinsic evidence.

Illustrations

1. Uncertain Price
   • A agrees in writing to sell his cow to B for Rs. 1500 or Rs. 2000.
   • Evidence cannot be given to prove which price was intended.
2. Alternative Consideration
   • A agrees in writing to sell a horse to B for “one lakh rupees or one lakh fifty thousand rupees.”
   • Oral evidence is inadmissible to clarify the price.
3. Blanks in a Document
   • A deed contains blanks.
   • Evidence cannot be given to show how the blanks were intended to be filled.

Underlying Principle

• A document must speak for itself.
• Where the defect or ambiguity is apparent, the court cannot rely on external evidence to interpret or amend it.
• Allowing such evidence would amount to rewriting the contract, which is not permitted.

Use of Internal Evidence

• Although extrinsic evidence is barred,
• The court may interpret the document by:
  • Reading it as a whole, and
  • Using statements contained in one part of the document to clarify another part.
• This is permissible only when the clarification arises from the document itself.

Judicial Interpretation
In Pardeep Kumar v. Mahaveer Pershad, a lease deed contained blanks regarding the date of commencement. However, another clause stated that the first installment of rent was payable on a particular date. The High Court held that:

• The date of payment of the first installment could reasonably be treated as the date of commencement.
• This was allowed because the clarification was derived from the internal contents of the document, not from oral evidence.

Key Points

• Section 96 applies only to patent ambiguity.
• Oral or extrinsic evidence is not admissible.
• Essential defects cannot be cured from outside the document.
• Internal consistency of the document may be used for interpretation.

Conclusion
Section 96 of the Bharatiya Sakshya Adhiniyam, 2023 excludes evidence to explain or amend documents that are ambiguous or defective on their face. The provision reinforces the principle that written instruments must be clear and complete, and courts cannot rely on external evidence to cure patent defects.
