Bharatiya Sakshya Adhiniyam, 2023
The Bharatiya Sakshya Adhiniyam, 2023 (BSA) is India’s general statute governing the relevance, admissibility, proof and evaluation of evidence. It came into force on 1 July 2024 and replaced the Indian Evidence Act, 1872 for proceedings governed by the new law.
The BSA contains 170 sections across 12 chapters and expressly integrates electronic and digital records into the statutory definition of documents and documentary evidence. For law students, it should be studied as the third pillar of the new criminal-law framework: the BNS defines offences, the BNSS governs procedure, and the BSA determines what material the court may receive and how it is proved.
- Section 1 applies the BSA to judicial proceedings before courts, including courts-martial, but not to affidavits presented to a court or officer, or proceedings before an arbitrator.
- Section 2 expressly includes electronic and digital records within “document” and “documentary evidence”.
- Section 3 is the foundational relevancy rule: evidence may be given of facts in issue and facts declared relevant by the Adhiniyam.
- Admissions begin at Section 15; confession rules are concentrated in Sections 22–24.
- Section 26 contains the important rule for statements of persons who are dead or otherwise unavailable, including the statutory foundation for dying declarations.
- Sections 57–60 distinguish primary and secondary evidence and the conditions for proving documents by secondary evidence.
- Sections 61–63 contain the modern electronic-record framework; Section 63 includes a statutory certificate and Schedule.
- The burden-of-proof chapter begins at Section 104; Section 108 addresses an accused relying on General Exceptions and Section 109 concerns facts especially within knowledge.
- Witness competency begins at Section 124 and examination of witnesses at Section 140.
- Section 170 preserves the old Evidence Act for specified proceedings already pending immediately before commencement of the BSA.
- Scope, definitions and transition from the Evidence Act
- Facts in issue, relevant facts and res gestae
- Admissions, confessions and statements of unavailable persons
- Opinion evidence, character and judicial notice
- Oral, documentary and electronic evidence
- Primary evidence, secondary evidence and Section 63 certificate
- Burden of proof and statutory presumptions
- Estoppel
- Competency and privileges of witnesses
- Examination-in-chief, cross-examination, re-examination and contradictions
Official Statutory Source and Commencement
The BSA received Presidential assent on 25 December 2023 and came into force on 1 July 2024. The official text can be checked on India Code and through the Ministry of Home Affairs New Criminal Laws portal.
Its long title is significant: it is an Act to consolidate and provide the general rules and principles of evidence for fair trial. The BSA is therefore not merely a renumbered Evidence Act. It retains much of the classical evidence structure while expressly modernising digital records and electronic modes of proof.
Part I — Structure of the BSA: 12 Chapters, 170 Sections
| Chapter | Sections | Subject |
|---|---|---|
| I | 1–2 | Preliminary: application and definitions |
| II | 3–50 | Relevancy of facts |
| III | 51–53 | Facts which need not be proved |
| IV | 54–55 | Oral evidence |
| V | 56–93 | Documentary evidence, including electronic records |
| VI | 94–103 | Exclusion of oral evidence by documentary evidence |
| VII | 104–120 | Burden of proof and presumptions |
| VIII | 121–123 | Estoppel |
| IX | 124–139 | Witnesses |
| X | 140–168 | Examination of witnesses |
| XI | 169 | Improper admission and rejection of evidence |
| XII | 170 | Repeal and savings |
Section 1: Where Does the BSA Apply?
The BSA applies to all judicial proceedings in or before a court, expressly including courts-martial. It does not apply to affidavits presented to a court or officer or to proceedings before an arbitrator. This scope provision should be stated in any introductory examination answer because it immediately shows that “law of evidence” does not apply identically to every fact-finding process.
Section 2: The Digital Definition of “Document” and “Evidence”
Section 2 expressly recognises that a document includes electronic and digital records. Its illustrations refer to material such as emails, server logs, documents on computers, laptops or smartphones, messages, websites, locational evidence and voicemail messages stored on digital devices.
The definition of evidence likewise includes witness statements given electronically and documents—including electronic or digital records—produced for the court’s inspection. This is one of the most important drafting signals in the new law: digital evidence is no longer treated as an awkward add-on to a paper-document regime.
Part II — Relevancy of Facts: Sections 3–50
Section 3: Facts in Issue and Relevant Facts
Section 3 is the gateway provision. Evidence may be given of the existence or non-existence of every fact in issue and of other facts that the Adhiniyam declares relevant—and of no others. The distinction is fundamental.
A fact from which a right, liability or disability asserted or denied in the proceeding necessarily follows. In a murder trial, causation and intention may be facts in issue.
A connected fact made legally relevant by one of the statutory rules, such as motive, preparation, conduct, identity, conspiracy or a fact forming part of the same transaction.
Closely Connected Facts and the Same Transaction
Section 4 makes facts relevant when they are so connected with a fact in issue or relevant fact as to form part of the same transaction, even if they occurred at different times or places. This is the statutory field commonly associated with the doctrine of res gestae.
Motive, Preparation and Conduct
Section 6 makes motive, preparation and relevant previous or subsequent conduct admissible within the statutory conditions. Motive is not a substitute for proof of the offence, but in a circumstantial case it can materially strengthen or weaken an inference when connected with other proved facts.
Conspiracy
Section 8 deals with things said, done or written by conspirators in reference to their common intention after the common intention is first entertained, subject to the statutory threshold. Students should distinguish this evidence rule from the substantive offence of criminal conspiracy under the BNS.
Admissions, Confessions and Dying Declarations
| Concept | Key BSA Provision | Core Point |
|---|---|---|
| Admission | §15 onwards | A broad category of statements suggesting an inference as to a fact in issue or relevant fact. |
| Confession | §§22–24 | Criminal statements admitting guilt are subject to stricter rules, especially inducement/coercion and police-confession restrictions. |
| Statement of unavailable person | §26 | Specified statements may become relevant where the maker is dead, cannot be found, is incapable, or cannot reasonably be procured. |
| Expert opinion | §39 | Expertise may assist on science, technical subjects, handwriting, digital forensics and other specialist questions. |
A recurring exam mistake is to equate admission and confession. Every confession is evidentially a form of admission, but every admission is not a confession. The criminal law imposes stricter admissibility rules because of the risk of coercion and the consequences of self-incrimination.
Part III — Oral, Documentary and Electronic Evidence
Sections 54–55: Oral Evidence Must Be Direct
The BSA preserves the principle that oral evidence must ordinarily be direct. A witness proves what that witness saw, heard or otherwise perceived. Hearsay is therefore generally excluded unless the statement falls within a statutory route making it relevant.
Sections 57–60: Primary and Secondary Evidence
| Issue | Primary Evidence | Secondary Evidence |
|---|---|---|
| Statutory focus | §57 | §58; conditions in §60 |
| Basic idea | The original or legally recognised primary form | Recognised substitutes where statutory conditions are met |
| Examples | Original agreement, original record, recognised original electronic form | Certified copies, accurate mechanical copies, compared copies, written admissions and other listed forms |
| Common error | Assuming only paper can be “original” | Assuming every photocopy is automatically admissible |
Section 58 expands and modernises the list of secondary evidence. Yet the basic discipline remains: identify the original, explain why it is not being produced, identify the precise statutory category of secondary evidence, and satisfy the conditions under Section 60.
Sections 61–63: Electronic and Digital Evidence
Section 61 prevents exclusion merely because a record is electronic or digital. Subject to Section 63, such a record has the same legal effect, validity and enforceability as other documents. Section 62 directs proof of electronic-record contents through Section 63. Section 63 then lays down the conditions for admissibility of computer output and the certificate mechanism.
- The certificate accompanies the electronic record when it is submitted for admission under the statutory route.
- It identifies the electronic record and explains how it was produced.
- It provides appropriate device/source particulars.
- It addresses the statutory regular-use and reliability conditions.
- The Schedule expressly contemplates device/source details and hash values.
- The statutory Schedule contains separate certification components, including the party/source information and expert certification framework.
For litigation, “screenshot = proof” is an unsafe assumption. A screenshot may be relevant, but questions of authenticity, completeness, source, device custody, extraction method, metadata, certificate compliance and evidentiary weight remain separate. The same principles matter in criminal cases, commercial disputes and family litigation involving chats, recordings and financial records; see our practical guide on evidence in divorce cases.
Electronic Evidence Preservation Checklist
- Preserve the original device or source where reasonably possible.
- Do not crop, edit or overwrite the original file.
- Export complete chats instead of relying only on isolated screenshots.
- Preserve email headers, metadata, logs and source information where relevant.
- Record who extracted or copied the material and when.
- Maintain chain of custody in forensic or criminal matters.
- Generate and preserve hash values where appropriate.
- Prepare the Section 63 certificate in the statutory form when the provision applies.
Sections 94–103: Written Terms versus Oral Evidence
Where the terms of a contract, grant or other disposition have been reduced to writing, Section 94 ordinarily requires proof through the document itself or admissible secondary evidence. Section 95 then restricts oral evidence that seeks to contradict, vary, add to or subtract from the written terms, subject to its statutory provisos.
For contract and property problems, students should therefore distinguish between proving the terms of the document and proving an independent fact such as fraud, illegality, want of capacity, failure of consideration or another matter falling within the statutory exceptions.
Part IV — Burden of Proof, Presumptions and Estoppel
Sections 104–109: Core Burden Rules
| Section | Rule | Exam Use |
|---|---|---|
| 104 | General burden on the person asserting facts necessary for judgment | Start every burden-of-proof answer here |
| 105 | Burden lies on the person who would fail if no evidence were given | Useful for civil-procedure style problems |
| 106 | Burden as to a particular fact | Who wants the court to believe that fact? |
| 107 | Foundational facts required to make other evidence admissible | Death before dying declaration; loss before secondary evidence |
| 108 | Accused relying on General Exceptions or special exception/proviso | Connect with BNS General Exceptions |
| 109 | Fact especially within a person’s knowledge | Does not erase prosecution’s primary criminal burden |
In criminal law, the prosecution remains responsible for proving the ingredients of the offence. Specific statutory burdens—such as Section 108 when the accused invokes an exception—must be analysed separately rather than used to reverse the entire presumption of innocence.
May Presume, Shall Presume and Conclusive Proof
The court may regard the fact as proved unless disproved, or may call for proof.
The court must regard the fact as proved unless and until it is disproved.
Once the foundational fact is proved, the other fact must be treated as proved and contrary evidence is not permitted.
Sections 121–123: Estoppel
Estoppel prevents a person who intentionally caused or permitted another to believe a fact and act upon it from later denying that fact in the relevant dispute. It is a rule of consistency and fairness in proof, not a general mechanism for creating a legal right where substantive law forbids one.
Part V — Witnesses and Examination of Witnesses
Section 124: Who May Testify?
The starting rule is competency, not exclusion. Every person is competent to testify unless the court considers that the witness is prevented from understanding the questions or giving rational answers because of tender years, extreme old age, disease of body or mind, or a similar cause. A person of unsound mind is therefore not automatically incompetent.
Witness Unable to Communicate Verbally
Section 125 allows evidence by writing or signs and provides for interpreter or special-educator assistance where necessary; the statement is to be videographed in the circumstances stated by the section.
Accomplice and Number of Witnesses
Section 138 deals with accomplice testimony and Section 139 states that no particular number of witnesses is required to prove a fact. Quality and legal sufficiency matter more than a mechanical witness count.
Sections 140–168: Examination, Cross-Examination and Judicial Control
The examination chapter regulates the order of witnesses, admissibility foundations, examination-in-chief, cross-examination, re-examination, leading questions, contradiction by previous statements, questions testing veracity, impeachment of credit, corroboration, refreshing memory, production of documents and the Judge’s power to ask questions or order production.
| Stage | Primary Function | Typical Restriction |
|---|---|---|
| Examination-in-chief | Witness presents the party’s affirmative evidence | Leading questions ordinarily restricted except as permitted |
| Cross-examination | Tests accuracy, credibility, omissions, contradictions and alternative hypotheses | Questions remain subject to judicial control and statutory protections |
| Re-examination | Explains matters arising in cross-examination | New matter generally requires permission and may reopen cross on that matter |
For criminal trials, the evidence rules operate together with the procedural stages explained in our BNSS cognizance, charge and trial guide. The BSA answers whether and how a fact can be proved; the BNSS answers when and through what procedure that evidence is received.
Part VI — BSA versus Indian Evidence Act, 1872
| Issue | Indian Evidence Act | BSA 2023 |
|---|---|---|
| Overall size | 167 sections | 170 sections |
| Digital records | Added through amendments and Section 65B framework | Electronic/digital records integrated into definitions and proof framework |
| Electronic certificate | Section 65B certificate jurisprudence | Section 63 plus statutory Schedule and hash/source details |
| Electronic witness statements | Not framed as centrally in original definitions | Definition of evidence expressly includes statements given electronically |
| Transition | Former general evidence law | Section 170 saves specified proceedings already pending before commencement |
Common Evidence-Law Mistakes
- Using old Evidence Act section numbers without checking the BSA equivalent.
- Confusing relevance with admissibility and admissibility with evidentiary weight.
- Treating every photocopy as secondary evidence without proving the Section 60 foundation.
- Assuming a screenshot alone proves a complete digital conversation.
- Failing to preserve source devices, metadata and chain of custody.
- Using an isolated message while omitting the surrounding conversation necessary to understand its effect.
- Treating an admission as automatically conclusive.
- Treating a police statement as a judicial confession.
- Invoking Section 109 “special knowledge” as though it removes the prosecution’s burden to prove the offence.
- Confusing witness competency with witness credibility.
Part VII — How to Solve an Evidence-Law Problem Question
- Identify the fact in issue. What must the party actually prove?
- Ask whether the proposed fact is relevant. Identify the BSA rule connecting it to the fact in issue.
- Identify the form of evidence. Oral, documentary, electronic, expert, admission, confession or statement of an unavailable person?
- Check exclusionary rules. Police confession, hearsay, written-term rule, privilege or another statutory bar?
- Check the mode of proof. Primary evidence, secondary evidence, certified copy, witness testimony, Section 63 certificate or expert foundation?
- Identify the burden. Who must establish the foundational fact and to what standard?
- Check presumptions. Is the provision “may presume”, “shall presume” or conclusive proof?
- For witness evidence, separate competency from credibility.
- For contradictions, identify the previous statement and follow the statutory contradiction procedure.
- Conclude separately on relevance, admissibility and weight. These are three different questions.

Frequently Asked Questions
What replaced the Indian Evidence Act, 1872?
The Bharatiya Sakshya Adhiniyam, 2023 is the current central evidence statute for proceedings governed by it. It came into force on 1 July 2024, subject to the savings clause in Section 170.
How many sections are there in the BSA?
The BSA contains 170 sections across 12 chapters, followed by the statutory Schedule connected with the Section 63 electronic-evidence certificate.
Does BSA apply to courts-martial?
Yes. Section 1 expressly includes judicial proceedings before courts, including courts-martial.
Are electronic records admissible?
Yes. Section 61 prevents exclusion merely because the material is electronic or digital, but the relevant proof and admissibility requirements—including Section 63 where applicable—must still be satisfied.
Is every photocopy secondary evidence?
No. The proposed copy must fit a recognised form of secondary evidence and the statutory conditions permitting secondary evidence must be established.
Is a WhatsApp screenshot enough by itself?
Not necessarily. Relevance, authenticity, completeness, device/source proof, Section 63 compliance and evidentiary weight must be examined separately.
Does Section 109 shift the entire criminal burden to the accused?
No. It deals with facts especially within a person’s knowledge. The prosecution’s primary obligation to prove the ingredients of the offence remains central.
The Bharatiya Sakshya Adhiniyam should be studied as a sequence of questions rather than a catalogue of sections: Is the fact relevant? Is the evidence admissible? Has it been proved in the legally prescribed manner? Who carries the burden? What presumption applies? How should the witness or document be tested?
The most significant practical change is the deeper statutory integration of electronic and digital material. Sections 61–63, the Schedule, device/source information and hash-based certification make digital-evidence literacy indispensable for modern litigation.
Revision sequence: relevancy → admissions/confessions → oral evidence → documentary/electronic evidence → burden and presumptions → estoppel → witnesses → examination → repeal and savings.
Academic note: This article is for legal education and examination preparation. Evidence questions are fact-sensitive. Special statutes, transitional provisions and later judicial interpretation may affect the applicable rule, so the current statutory text and full judgments should be checked before professional reliance.
