Civil litigation often raises an important procedural question:
Can courts rely on oral evidence to contradict, vary, or alter the terms of a written contract?
The Supreme Court in S. Nazeer Ahmed v. State Bank of Mysore (2007) clarified one of the most important evidentiary principles governing civil disputes:
When parties reduce their agreement into writing, the document itself becomes the best evidence of its terms.
The judgment remains an important authority on the Indian Evidence Act, documentary evidence, interpretation of contracts, and admissibility of oral evidence in civil litigation. The Court explained the relationship between written contracts and oral testimony and clarified the limits of proving facts outside contractual documents.
Introduction
Civil disputes involving contracts, banking transactions, mortgages, guarantees, and commercial agreements often involve:
Conflicting oral claims attempting to modify written documents

The Supreme Court addressed this issue by interpreting:
- Sections 91 and 92 of the Indian Evidence Act, 1872
- Rules relating to documentary evidence
- Admissibility of oral evidence in contractual disputes
The Court clarified:
When a contract is reduced into writing, the writing itself ordinarily governs the rights and obligations of parties.

Judgment of the Supreme Court
The Supreme Court clarified:
When parties intentionally reduce their agreement into writing, the document itself becomes primary evidence of its contents.
The Court explained:
Section 91 embodies the “best evidence rule”
Meaning:
The contents of a written contract must ordinarily be proved through the document itself.
The Court further clarified:
Section 92 prohibits oral evidence that contradicts, varies, adds to, or subtracts from written contractual terms.
The Supreme Court emphasized:
Courts must primarily interpret rights from the written document and not subsequent oral assertions.
However, the Court also clarified:
Oral evidence may still be admissible in exceptional situations recognized by law.
Sections 91 and 92 Explained
Section 91 – Best Evidence Rule
Section 91 provides:
When terms of a contract or transaction are reduced into writing, the document itself becomes the best evidence of those terms.
Thus:
- Written contracts must be proved through the document
- Oral evidence cannot replace written proof
- Courts must examine documentary evidence first
Section 92 – Exclusion of Oral Evidence
Section 92 provides:
Oral evidence cannot contradict, vary, add to, or subtract from terms of a written contract
The Court clarified:
Parties cannot bypass written contractual obligations through later oral claims.
Exceptions to Section 92
The Court explained that oral evidence may still be admissible to prove:
- Fraud
- Mistake
- Invalidity of document
- Separate oral agreements in certain situations
- Subsequent modification where legally permissible
Thus:
The exclusion of oral evidence is important but not absolute.
Legal Principles Established
1. Written Document Is Best Evidence
The Court held:
A written contract ordinarily speaks for itself.
Rights and obligations must be gathered from the document.
2. Oral Evidence Cannot Contradict Written Terms
The Court clarified:
Oral assertions cannot ordinarily vary contractual terms recorded in writing.
3. Sections 91 and 92 Work Together
The Court emphasized:
Section 91 governs proof of documents while Section 92 restricts contradictory oral evidence.
4. Limited Exceptions Exist
The judgment clarified:
Oral evidence may still be admitted in legally recognized exceptional circumstances.
