Document: The Building Block of Written Evidence

The legal concept of “document” determines the scope of a vast number of offences and evidentiary rules. Under BNS Section 2(8), a document is any matter expressed or described upon any substance by letters, figures, or marks, intended to be used as evidence. This definition is deliberately wide—it covers ancient palm-leaf manuscripts, modern emails, contracts, court orders, land records, photographs, maps, and audio-visual recordings. The intent to use the matter as evidence is the key element.

Substances on Which Documents May Be Made

The BNS/IPC definition expressly provides that documents may be expressed on any substance—not just paper. This encompasses: paper and parchment; stone, wood, metal, bark, or skin; film, magnetic tape, or optical disc; electronic and digital records (expressly included via the IT Act, 2000 definition). This comprehensive scope ensures that the law does not lag behind technological developments in record-keeping.

Electronic Records as Documents

The express inclusion of “electronic record” (as defined in the Information Technology Act, 2000 Section 2(1)(t)) was a significant addition. Under BSA 2023 Section 61, an electronic record produced from a properly maintained computer system is admissible as evidence of the facts contained in it, provided a certificate under Section 63 BSA is furnished. This provision is the primary vehicle for admitting digital evidence—emails, WhatsApp messages, CCTV footage, and data from electronic devices—in court proceedings.

Documents in Evidence Law: BSA Classification

The Bharatiya Sakshya Adhiniyam, 2023 classifies documents into: Public documents (BSA Section 72)—forming acts of sovereign authority, official bodies, courts, and registers maintained by public officers; and Private documents (BSA Section 73)—all other documents. Public documents can be proved by certified copies; private documents must generally be proved by primary evidence (original) or secondary evidence (where permitted).

Documents in Criminal Law

Forgery (BNS Section 336) is the making of a false document. For forgery, the subject matter must be a “document” as defined. This has led to significant litigation about whether particular items (blank cheques, photographs, computer printouts) qualify as documents. The Supreme Court in State v. S.J. Choudhary (1996) 2 SCC 428 held that a typewriter ribbon is a document because marks on it express letters. Courts generally interpret the definition expansively to prevent technical escapes from forgery prosecutions.

“A document in law is not limited to paper writing; it is any matter capable of carrying and conveying information intended to be used as proof. The medium is irrelevant; the intent to evidence is everything.”
