IEA to BSA Comparative Section Mapping — A Translation Guide

The Bharatiya Sakshya Adhiniyam, 2023 (BSA) — which replaced the Indian Evidence Act, 1872 (IEA) on 1 July 2024 — re-enacts Stephen's 1872 architecture with a tightened structure, modernised language, and a small but consequential set of substantive additions. For the trial advocate working with case files spanning both regimes, and for the judiciary aspirant preparing for an examination that may be set in either statutory vocabulary, a working translation guide between the IEA's 167 sections and the BSA's 170 sections is indispensable. This chapter provides that guide — chapter-by-chapter — and flags the substantive shifts the BSA introduces.

The doctrinal payoff of the mapping is that no IEA case becomes inaccessible under the BSA. Every Supreme Court and High Court decision interpreting Sections 5, 32, 65B, 105, 113A, or any other IEA provision continues to govern the corresponding BSA section. The translation is mostly section-for-section; the case law is fully portable. Read this chapter together with the chapter on Evidence Act and BSA for the larger framework, and use it as a quick lookup whenever you encounter an IEA reference in older case law and need to find the BSA equivalent.

The structural shift: 167 IEA sections to 170 BSA sections

The IEA had 167 sections divided into three parts: Part I (Relevancy of Facts), Part II (Proof), and Part III (Production and Effect of Evidence). The BSA preserves this tripartite structure but reorganises some material. The numbering differs throughout — the BSA has 170 sections (counting amalgamated provisions), with a slight shift produced by the consolidation of some IEA provisions and the addition of new ones. The cumulative effect is that BSA section numbers run roughly two to three numbers ahead of the IEA's by the middle of the statute, and the gap stabilises by the end.

Chapter-by-chapter correspondence

The mapping below tracks the BSA's chapters (and the corresponding IEA provisions) and flags the substantive shifts where they exist.

Preliminary (Sections 1 and 2 BSA / Sections 1 to 4 IEA)

Section 1 BSA = Section 1 IEA. Short title and commencement. The IEA's territorial-extent provision is dropped, reflecting the post-2019 constitutional position on Jammu & Kashmir. Section 2 BSA consolidates the IEA's Sections 3 (interpretation) and 4 (presumptions) into a single alphabetically-lettered definitions and interpretation clause. New Sub-section (2) imports defined terms from the BNS, BNSS, and IT Act, 2000. Substantive additions include the expanded definition of document under Section 2(1)(d) BSA.

Relevancy of Facts (Sections 3 to 50 BSA / Sections 5 to 55 IEA)

This is the largest chunk of the statute. The correspondence is one-to-one with offsetting numbering. Section 5 IEA (evidence may be given of facts in issue and relevant facts) becomes Section 3 BSA. Section 6 IEA (res gestae) becomes Section 4 BSA. Section 7 IEA (occasion, cause, effect) becomes Section 5 BSA, with the small addition "or relevant facts" in the heading. Section 8 IEA (motive, preparation, conduct) becomes Section 6 BSA, with cosmetic illustration updates ("vakils" to "advocates", "man" to "person", "ravished" to "raped"). The chapter on relevancy of facts works through the architecture; res gestae under Section 4 BSA, statements by conspirators under Section 8 BSA, and facts showing state of mind under Section 12 BSA all carry forward their IEA case law without doctrinal interruption.

Within the relevancy chapter, the most consequential shift is in the definition of admissions (Sections 15 to 21 BSA / Sections 17 to 23 IEA), where archaic language updates and a paragraph restructuring tighten the drafting without altering the doctrine. The Section 21 BSA replacement of "barrister, pleader, attorney or vakil" with "advocate" is illustrative of the BSA's drafting style throughout.

Confessions (Sections 22 to 24 BSA / Sections 24 to 30 IEA)

The confessions chapter sees the BSA's most visible drafting reorganisation. Sections 24, 28, and 29 IEA on involuntary confessions are consolidated into Section 22 BSA, with the older Sections 28 and 29 IEA appearing as provisos. Sections 25 and 26 IEA on confessions to police and confessions in police custody are folded into Sections 23(1) and 23(2) BSA, with the discovery rule from Section 27 IEA appearing as the proviso to Section 23 BSA. Section 30 IEA on consideration of co-accused confessions becomes Section 24 BSA, with the new Explanation II that deems an absent-absconding accused's trial to be a joint trial under Section 24 BSA. The substantive doctrine — including Pulukuri Kotayya v. Emperor AIR 1947 PC 67 on the discovery rule — survives intact.

Statements by unavailable persons (Sections 26 BSA / Section 32 IEA)

Section 32 IEA — the celebrated provision on statements by persons who cannot be called as witnesses, including dying declarations — becomes Section 26 BSA. The doctrine from Pakala Narayana Swami v. Emperor (1939) 41 Bom LR 428 and the long line of dying-declaration cases is fully portable. The drafting updates include language modernisation ("namely" added; "ravished" replaced by "raped").

Statements made under special circumstances (Sections 28 to 33 BSA / Sections 34 to 39 IEA)

Section 34 IEA (entries in books of account) becomes Section 28 BSA. Section 35 IEA (entries in public records) becomes Section 29 BSA. Sections 36 and 37 IEA on maps, charts and laws become Sections 30 and 31 BSA. The architecture is preserved with offsetting numbering.

Judgments when relevant (Sections 34 to 38 BSA / Sections 40 to 44 IEA)

Section 40 IEA (previous judgments to bar a second suit) becomes Section 34 BSA. Section 41 IEA (relevancy of certain judgments in probate, matrimonial, admiralty, insolvency) becomes Section 35 BSA. Section 42 IEA on judgments not within Section 41 becomes Section 36 BSA. The chapter on judgments of courts when relevant works through these provisions in detail; the substantive case law on res judicata and binding nature of prior judgments is fully preserved.

Opinions (Sections 39 to 45 BSA / Sections 45 to 51 IEA)

Section 45 IEA (expert opinion) becomes Section 39 BSA. Section 45A IEA (electronic-record examiner's opinion) is preserved as Section 40 BSA. Sections 46 to 51 IEA on related opinion-evidence rules become Sections 41 to 45 BSA. The substantive doctrine on expert and opinion evidence — including the rules on handwriting comparison under Section 73 IEA (now Section 67 BSA) — carries forward without textual change.

Character (Sections 46 to 50 BSA / Sections 52 to 55 IEA)

The IEA's four character-evidence sections become four BSA sections with offsetting numbering. Section 52 IEA (character irrelevant in civil cases) becomes Section 46 BSA. Section 53 IEA (character of accused in criminal cases) becomes Section 47 BSA. Section 54 IEA (previous bad character) becomes Section 48 BSA. Section 55 IEA (character affecting damages) becomes Section 49 BSA. Section 50 BSA is a residual placeholder. The doctrine on character when relevant is fully preserved.

Facts which need not be proved (Sections 51 to 53 BSA / Sections 56 to 58 IEA)

Section 56 IEA (judicial notice) becomes Section 51 BSA. Section 57 IEA (facts of which the court must take judicial notice) becomes Section 52 BSA, with the list updated for contemporary contexts. Section 58 IEA (admitted facts) becomes Section 53 BSA. The doctrine on judicial notice and admitted facts is fully preserved, with cosmetic updates reflecting the post-Constitution-of-India statutory landscape.

Oral evidence (Sections 54 to 55 BSA / Sections 59 to 60 IEA)

Section 59 IEA (proof of facts by oral evidence) becomes Section 54 BSA. Section 60 IEA (oral evidence must be direct) becomes Section 55 BSA. The doctrine on the direct-evidence rule, including the hearsay-exclusion architecture and the witness-must-have-perceived test, is fully preserved.

Documentary evidence (Sections 56 to 73 BSA / Sections 61 to 78 IEA)

The BSA's documentary-evidence chapter contains some of the most consequential textual shifts. Section 61 IEA becomes Section 56 BSA. Sections 62 and 63 IEA on primary and secondary evidence become Sections 57 and 58 BSA. Sections 64 and 65 IEA on documents to be proved by primary evidence and cases where secondary evidence may be given become Sections 59 and 60 BSA. Sections 65A and 65B IEA on electronic records are reorganised: Section 65A is absorbed into the broader scheme, while Section 65B IEA becomes Section 63 BSA with the substantive expansions covered in detail in that chapter.

Sections 66 to 73A IEA on attestation, handwriting, and proof of execution become Sections 61 to 70 BSA, with offsetting numbering. The substantive doctrine on proof of documents is fully preserved.

Public and private documents (Sections 74 to 90 BSA / Sections 74 to 90A IEA)

This chapter is the most numerically aligned. Sections 74 to 90 IEA on public documents, certified copies, and presumptions as to documents become Sections 74 to 90 BSA with minimal offsetting. Section 90A IEA on electronic records becomes Section 91 BSA with textual updates. The doctrine on public documents, the presumption of genuineness, and 30-year-old documents is preserved with cosmetic refinements.

Exclusion of oral by documentary (Sections 92 to 100 BSA / Sections 91 to 100 IEA)

The IEA's Sections 91 to 100 on exclusion of oral by documentary evidence become Sections 92 to 100 BSA with offsetting numbering. The doctrine — central to contract litigation, where oral terms are sought to be added to written contracts — is fully preserved.

Burden of proof (Sections 104 to 117 BSA / Sections 101 to 114 IEA)

Section 101 IEA (burden of proof) becomes Section 104 BSA. Sections 102 to 105 IEA on the various burden-allocations become Sections 105 to 108 BSA. Section 106 IEA (special knowledge) becomes Section 109 BSA. Sections 113A and 113B IEA on statutory presumptions in matrimonial and dowry cases become Sections 116 and 117 BSA. Section 114 IEA (court may presume existence of certain facts) becomes Section 119 BSA with the illustrations preserved. The chapter on burden of proof under Sections 104 to 117 BSA covers the substantive position.

Estoppel (Sections 121 to 123 BSA / Sections 115 to 117 IEA)

Sections 115 to 117 IEA on estoppel — including the foundational rule that a person who has by his declaration, act, or omission caused another to believe a thing to be true is estopped from denying it — become Sections 121 to 123 BSA. The doctrine, including the rich case-law on promissory estoppel, is fully preserved.

Witnesses (Sections 124 to 168 BSA / Sections 118 to 165 IEA)

The IEA's witness chapter — the longest in the statute — sees the most numerical offsetting. Section 118 IEA (who may testify) becomes Section 124 BSA. Sections 119 and 120 IEA on dumb witnesses and parties to suit become Sections 125 and 126 BSA. Section 121 IEA (judges and magistrates) becomes Section 127 BSA. Section 122 IEA (communication during marriage) becomes Section 128 BSA. The competency and privilege rules cover Sections 124 to 134 BSA in detail, preserving the spousal-privilege doctrine and the professional-privilege rules under Section 126 IEA (now Section 132 BSA).

Sections 135 to 165 IEA on the order and modes of examination of witnesses become Sections 134 to 168 BSA. Section 154 IEA (questioning own witness) becomes Section 157 BSA on hostile witnesses. Section 165 IEA (judge's power to put questions) becomes Section 168 BSA on the judge's power to put questions, with minor textual updates flagged in the BSA-IEA correspondence table.

Improper admission and rejection (Section 169 BSA / Section 167 IEA)

Section 167 IEA on improper admission and rejection of evidence becomes Section 169 BSA without substantive change. The materiality filter, the trial-versus-appeal preservation rule, and the entire body of case law remain controlling.

Repeals and savings (Section 170 BSA)

Section 170 BSA repeals the Indian Evidence Act, 1872 and saves anything done or any action taken under the IEA. The savings clause is the doctrinal bridge that ensures pre-1 July 2024 cases continue under the IEA while post-1 July 2024 cases run under the BSA — and that case law decided under the IEA continues to govern its BSA counterparts where the substantive doctrine is unchanged.

The substantive shifts: a focused list

Most of the BSA's changes are textual — modernised vocabulary, gender-neutral drafting, alphabetic clause-numbering, illustration updates. The substantive shifts are few but consequential:

1. Section 2(1)(d) BSA — expanded definition of document. Electronic and digital records are natively within the definition.
2. Section 2(2) BSA — harmonisation clause. Imports definitions from the BNS, BNSS, and IT Act.
3. Section 24 BSA Explanation II — joint-trial deeming. Absent-absconding accused's trial is deemed a joint trial for confession purposes.
4. Section 63 BSA — restructured certificate regime. Communication devices, semiconductor memory, schedule certificate, broader certifier class.
5. Drop of the territorial-extent clause. Section 1 BSA omits the IEA's exclusion of Jammu & Kashmir.
6. Drafting consolidations. Sections 28 and 29 IEA become provisos to Section 22 BSA; Sections 25 to 27 IEA are folded into Section 23 BSA.
7. Modern terminology throughout. "Vakil", "barrister", "pleader" replaced by "advocate"; "man" replaced by "person"; "ravished" replaced by "raped"; "coin" replaced by "currency"; "agents" replaced by "representatives".

None of these shifts overrules existing case law. The substantive doctrine — built up through Privy Council, Supreme Court, and High Court decisions over 150 years — remains controlling under the BSA.

Using the mapping in practice

Three working rules help the trial advocate and the aspirant navigate the dual regime:

• Cite both numbers. When invoking a provision, cite the BSA section first and the IEA section in parentheses — for example, "Section 26 BSA (previously Section 32 IEA)". This satisfies the BSA's new-law-first convention while preserving the IEA reference for cases litigated or decided under the older regime.
• Treat case law as portable. An IEA decision is a BSA decision unless the BSA's text has changed in a relevant way. The five substantive shifts listed above are the only places where careful reading of the BSA-specific position is required.
• Watch the date. Cases instituted before 1 July 2024 continue under the IEA; cases instituted on or after that date attract the BSA. The savings clause in Section 170 BSA preserves this transition.

Search-intent overlay: what to remember

For Civil Judge prelims, judiciary mains, and judicial-service interviews, four propositions on the BSA-IEA mapping recur:

1. The BSA replaces the IEA on 1 July 2024; pre-existing cases continue under the IEA via the savings clause.
2. The structural correspondence is one-to-one for most provisions, with offsetting numbering.
3. The substantive shifts are limited to five major changes — the expanded document definition, Section 2(2) harmonisation, Section 24 Explanation II, Section 63 BSA, and the dropped territorial-extent clause.
4. IEA case law is fully portable to the BSA except where the substantive shifts displace it.

The savings clause: how transition works in practice

Section 170 BSA's savings clause is the practical bridge between the two regimes. The clause provides that anything done or any action taken under the IEA continues to operate as if it had been done under the corresponding BSA provision. Three operational consequences follow. First, evidence recorded under the IEA in a pending pre-1-July-2024 trial does not need to be re-recorded; it carries forward into any continuation under the BSA. Second, certificates issued under Section 65B IEA before 1 July 2024 do not lose their validity merely because Section 63 BSA now governs new electronic-evidence regimes; they continue to operate within their original case files. Third, presumptions raised under Section 113A or 113B IEA in pending matrimonial trials carry forward as presumptions under Sections 116 and 117 BSA without re-pleading.

For trial advocates managing case files spanning the transition, the rule of thumb is: if the file was opened before 1 July 2024, run the IEA throughout; if opened on or after, run the BSA. Cases on appeal from pre-transition trials continue under the IEA; appeals from post-transition trials apply the BSA. The savings clause prevents the messy possibility of doctrinal limbo — every case is either under the IEA or under the BSA, not in some uncertain space between.

The IEA-to-BSA mapping for the most-tested provisions

Examiners regularly test a handful of high-frequency provisions. The translation table for these is worth committing to memory:

• Section 5 IEA (relevance) → Section 3 BSA
• Section 6 IEA (res gestae) → Section 4 BSA
• Section 8 IEA (motive, preparation, conduct) → Section 6 BSA
• Section 17 IEA (admission defined) → Section 15 BSA
• Section 24 IEA (involuntary confession) → Section 22 BSA
• Section 25 IEA (confession to police) → Section 23(1) BSA
• Section 26 IEA (confession in custody) → Section 23(2) BSA
• Section 27 IEA (discovery rule) → proviso to Section 23 BSA
• Section 30 IEA (co-accused confession) → Section 24 BSA
• Section 32 IEA (statements by unavailable persons) → Section 26 BSA
• Section 45 IEA (expert opinion) → Section 39 BSA
• Section 65B IEA (electronic records) → Section 63 BSA
• Section 101 IEA (burden of proof) → Section 104 BSA
• Section 105 IEA (burden of proving exception) → Section 108 BSA
• Section 113A IEA (abetment of suicide) → Section 116 BSA
• Section 113B IEA (dowry death) → Section 117 BSA
• Section 114 IEA (court may presume) → Section 119 BSA
• Section 154 IEA (hostile witness) → Section 157 BSA
• Section 165 IEA (judge's power) → Section 168 BSA
• Section 167 IEA (improper admission/rejection) → Section 169 BSA

This compact table covers about 80 percent of examination questions on the BSA-IEA mapping. The aspirant who internalises it has a working translation tool for both prelims and mains.

Conclusion

The IEA-to-BSA mapping is a translation guide, not a doctrinal revolution. The BSA preserves Stephen's 1872 architecture with tightened drafting, modernised vocabulary, and a small set of substantive additions tailored to contemporary conditions — chiefly the shift to electronic records and the closure of the absconding-accused gap in joint trials. The numerical offsetting between the two statutes is the surface phenomenon; the deep doctrine is unchanged.

For the aspirant, mastering the mapping means internalising both the structural correspondence and the focused list of substantive shifts. The structural correspondence allows IEA case law to travel into BSA practice; the substantive shifts demand careful attention to the BSA's specific drafting where electronic records, joint trials, harmonised definitions, and the territorial-extent clause are concerned. Read this chapter as a working reference — return to it whenever an IEA section number appears in older case law, and use it to find the BSA equivalent without losing the doctrinal continuity that makes the older case law operative under the new statute. The natural starting points for a deeper engagement with the BSA's substantive innovations are the chapters on the expanded document definition and on the restructured electronic-evidence regime — the two textual shifts that examiners are most likely to test in the BSA's first examination cycles.

Frequently asked questions

How many sections are in the BSA, and how does it compare to the IEA?

The BSA has 170 sections, compared to the IEA's 167. The increase is produced by drafting consolidations (Sections 25 to 27 IEA folded into Section 23 BSA, Sections 28 and 29 IEA folded into Section 22 BSA) offset by additions (the expanded Section 2 with its new sub-section (2), the new Explanation II to Section 24 BSA, the restructured Section 63 BSA on electronic evidence). The structural framework — three parts on relevancy, proof, and production-and-effect of evidence — is preserved from the IEA. The numerical offsetting between IEA section numbers and their BSA equivalents grows by approximately two to three through the middle of the statute and stabilises by the end.

Which IEA cases continue to govern under the BSA, and which do not?

All IEA cases continue to govern except where the BSA's text has substantively changed the underlying rule. The substantive shifts are limited: the expanded definition of document (Section 2(1)(d) BSA), the harmonisation clause (Section 2(2) BSA), the joint-trial deeming explanation (Explanation II to Section 24 BSA), the restructured electronic-evidence regime (Section 63 BSA), and the dropped territorial-extent clause (Section 1 BSA). For all other provisions, IEA case law — including foundational decisions like Pakala Narayana Swami (1939), Pulukuri Kotayya (1947), Bhuboni Sahu (1949), Anvar P.V. (2014), and Arjun Panditrao (2020) — is fully portable to the BSA's corresponding sections.

Does the BSA apply to cases instituted before 1 July 2024?

No. The BSA came into force on 1 July 2024 by Central Government notification. Section 170 BSA repeals the IEA but preserves anything done or any action taken under the IEA. The transition rule is that proceedings instituted before 1 July 2024 continue under the IEA; proceedings instituted on or after that date attract the BSA. Trial courts in 2026 may therefore be running both statutes simultaneously — the IEA in older files and the BSA in newer ones. The savings clause in Section 170 BSA ensures continuity.

What is the convention for citing provisions in BSA-era practice?

Cite the BSA section first and the IEA section in parentheses — for example, 'Section 26 BSA (previously Section 32 IEA)'. The convention satisfies the new-law-first rule that BSA-era courts are increasingly adopting, while preserving the IEA reference for older case law. In subsequent mentions within the same document, the BSA section alone is sufficient. When the case being relied upon was decided under the IEA, the case is cited in its original form — there is no need to translate the holding into BSA terms — but the doctrinal proposition should be restated using the BSA section number.

Where is the canonical correspondence table for BSA and IEA found?

The authoritative correspondence table is a 194-row mapping of every BSA provision to its IEA counterpart with a summary-of-comparison column. Most rows record 'no change' — the substantive doctrine is preserved. The rows that record changes are concentrated in the five substantive-shift areas: the expanded document definition, the harmonisation clause, the joint-trial explanation, the restructured electronic-evidence regime, and the dropped territorial-extent clause. The table is the single most useful working document for any practitioner or aspirant moving between the two regimes; the sections of this chapter summarise its main correspondences in narrative form.
