Definition
The rule that a party seeking to prove the contents of a document must produce the original document (primary evidence) — secondary evidence (copies, oral accounts of documents) is only admissible when the original is unavailable and proper grounds are shown.
The best evidence rule in Indian evidence law is codified in Sections 62-65 of the BSA 2023 (formerly Sections 62-65 IEA). Primary evidence is the document itself — the original. Secondary evidence includes certified copies, copies made from originals, counterparts of documents, and oral accounts of the document's contents. Secondary evidence is only admissible in the specific situations listed in Section 63 BSA: original is in possession of the adverse party or a third party who refuses to produce it; original is lost or destroyed; original cannot be easily moved; existence of the original is not disputed; or original is a public document. The rule's purpose: to prevent fraud, alteration, and misrepresentation that could occur if copies were routinely substituted for originals.
Statutory Definition
Section 62, Bharatiya Sakshya Adhiniyam (BSA), 2023 (formerly Section 62 IEA): 'Primary evidence means the document itself produced for the inspection of the court.' Section 63 BSA (formerly Section 63 IEA): 'Secondary evidence means and includes — (1) certified copies given under the provisions hereinafter contained; (2) copies made from the original by mechanical processes...; (3) copies made from or compared with the original; (4) counterparts of documents as against the parties who did not execute them; (5) oral accounts of the contents of a document given by some person who has himself seen it.'
Etymology & Origin
The 'best evidence' rule derives from the 18th-century English rule formulated by Lord Harwicke: 'The best evidence the nature of the case will admit must be produced.' The logic: if better evidence exists (the original), producing inferior evidence (a copy) raises the suspicion that the original, if produced, would be unfavourable.

Best Evidence Rule: The Original or a Good Reason
The best evidence rule operates on a simple principle: if you have the original, produce it. A copy might be accurate — but it might also have been altered, incompletely reproduced, or selectively excerpted. The original speaks for itself; a copy speaks through the person who made it, introducing a chain of trust. The best evidence rule minimises this chain and reduces the opportunity for fraud.
When Secondary Evidence Is Admissible: Section 63 BSA
Secondary evidence of a document's contents is admissible only in six situations: (a) original is in the possession or power of the adverse party or a third party who will not produce it on notice; (b) original has been destroyed or lost — though the party seeking to use secondary evidence must prove the loss/destruction; (c) original is not easily movable — a large signboard, an inscription on a wall; (d) original is a public document (public documents may be proved by certified copies — Section 76-77 BSA); (e) no original ever existed — the document was directly made in multiple counterparts, each being an original for the parties who signed it; or (f) the original is admitted by the other side to exist but they refuse to produce it.
Electronic Records: Section 63 BSA Extended
The BSA 2023 has significantly updated the best evidence rule for electronic records. Under Section 63 BSA, electronic records are treated as primary evidence if they are the original file — a printout or display of an electronic record is secondary evidence. However, electronic records are admissible as evidence if a certificate under Section 63(4) BSA (formerly Section 65B IEA) is provided — certifying that the electronic record was produced by a computer that was regularly used and functioning properly. The Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020) 7 SCC 1 judgment clarified that the Section 65B certificate must be obtained from the person who is in control of the computer system.
“The best evidence rule says: if you want the court to act on the contents of a document, show the document. A copy is a copy — and a copy carries the risk that it is not a faithful reproduction. The original speaks with an authority a copy can never fully replicate.”
