Every rule about proving a document that follows in the Bharatiya Sakshya Adhiniyam, 2023 (BSA) — what an original is, when a copy will do, how electronic records are handled, when notice must be served — rests on a single classification stated at the very start of the chapter. Section 56 opens the law of documentary evidence with one clean proposition: the contents of a document may be proved in one of two ways, by primary evidence or by secondary evidence. It is the foundation on which Sections 57 to 64 are built, and it is where any question about proving a document properly begins.
56. Proof of contents of documents. The contents of documents may be proved either by primary or by secondary evidence.
Section 56 reproduces Section 61 of the Indian Evidence Act, 1872 (IEA) without any change. Its brevity is deliberate. It is not meant to resolve a dispute on its own; it is meant to frame every dispute that follows by fixing, at the outset, the exhaustive two-fold scheme for proving what a document says.
Two categories, and only two
The force of Section 56 lies in the word "either." The contents of a document may be proved either by primary or by secondary evidence — and by nothing else. There is no third category. Whatever a party wishes to place before the court to establish a document's contents must fall into one of these two boxes: it is either the original itself (primary evidence) or one of the recognised substitutes for it (secondary evidence). This exhaustive classification is what gives the rest of the chapter its logic. Once the modes of proof are limited to two, the natural next questions are what each mode consists of, and when the substitute may be used in place of the original.
It is worth being precise about the scope of the section. Section 56 governs proof of the contents of a document — what it says. It is not concerned with proving that a document is genuine, or that a signature is authentic, or that an electronic record has not been tampered with; those questions are handled by later provisions on execution, attestation, signatures, and presumptions. Keeping the "contents" question separate from the "authenticity" question is the first discipline the chapter teaches, and Section 56 is where that separation starts.
The map of the chapter Section 56 opens
Because Section 56 is a gateway, the clearest way to understand it is to see how the sections that follow fill in the scheme it announces. This run of articles has worked through Chapter V's documentary-evidence provisions in sequence; Section 56 is where they all converge.
| Section | What it settles |
|---|---|
| 56 | Contents are proved either by primary or by secondary evidence — the two-fold scheme. |
| 57 | What primary evidence is — the original itself, now including qualifying electronic records. |
| 58 | What secondary evidence is — the eight recognised substitutes for the original. |
| 59 | Primary evidence is the rule; secondary is the exception. |
| 60 | The seven cases in which secondary evidence may be given. |
| 61–63 | The electronic-evidence regime — admissibility in principle, the special route, and the certificate mechanism. |
| 64 | The notice to produce that unlocks secondary evidence when the original is in another's hands. |
Where electronic records fit the two-fold scheme
One of the quieter achievements of the BSA is that it fits digital material into Section 56's classification rather than treating it as a separate world. An electronic record is not a third kind of evidence outside the primary/secondary divide; it sits within it. Under the expanded Explanations to Section 57, a qualifying electronic record — one produced from proper custody, or stored across multiple files — can be primary evidence. Where it is offered instead as a computer output standing in for the original, it is secondary evidence, proved through the special regime of Sections 62 and 63. Either way, the contents of an electronic document are still being proved "either by primary or by secondary evidence," exactly as Section 56 says. The dedicated electronic-evidence provisions are refinements within the two-fold scheme, not exceptions to it.
This is why Section 56 has aged so well. Written for a world of paper, its abstraction — contents are proved by the original or by a substitute for it — was general enough to absorb technologies its drafters never imagined. The categories did not need rewriting to accommodate emails, databases, or video; only the content of each category had to be updated, which is precisely what Sections 57 to 63 do.
The dichotomy behind the case law
Almost every documentary-evidence dispute that reaches the higher courts is, at bottom, an argument about which side of the Section 56 line a piece of evidence falls on. When the Supreme Court insists that a party lay the foundation for a copy before it can be received — as it did in Jagmail Singh v. Karamjit Singh, (2020) 5 SCC 178, and in requiring that a copy be authenticated as a true copy of the original in M. Chandra v. M. Thangamuthu, (2010) 9 SCC 712 — it is policing the boundary Section 56 draws. Secondary evidence is offered precisely because primary evidence is unavailable, and the whole apparatus of foundations, notices, and certificates exists to make sure the move from one category to the other is justified. Section 56 is the quiet premise those judgments never have to restate, because it is assumed in every one of them.
Key Takeaways
- The chapter's gateway: Section 56 opens the law of documentary evidence by fixing how a document's contents may be proved.
- Two categories only: contents may be proved either by primary or by secondary evidence — an exhaustive, two-fold scheme with no third option.
- Contents, not authenticity: the section governs what a document says, leaving genuineness, execution, and signatures to later provisions.
- Unchanged from Section 61 IEA: the provision is carried over verbatim.
- A preference, not a free choice: Section 59 ranks the two categories, making primary evidence the rule and secondary the exception.
Conclusion
Section 56 is the shortest possible statement of a very large idea. In one line it establishes the entire architecture of documentary proof: two modes, primary and secondary, and nothing outside them. Everything this run has covered — the definition of the original in Section 57, the catalogue of substitutes in Section 58, the primacy rule in Section 59, the exceptions in Section 60, the electronic-evidence framework in Sections 61 to 63, and the notice-to-produce machinery in Section 64 — is an elaboration of the choice Section 56 first names. It carries Section 61 of the 1872 Act forward untouched, and it remains the natural starting point for anyone asking the most basic question in the law of evidence: how do I prove what this document says?
