BNS, BNSS & BSA Decoded: New Criminal Laws Cheat Sheet for Judiciary 2026

The clock is ticking. With 33rd BPSC Bihar Judicial Service Prelims scheduled for 3 June 2026, just 24 days from today, and notifications for UP PCS-J (218 vacancies), MP Civil Judge, and Delhi Judicial Service all expected through Q3 and Q4, one section of the syllabus has rewritten how examiners think: the three new criminal laws — Bharatiya Nyaya Sanhita (BNS) 2023, Bharatiya Nagarik Suraksha Sanhita (BNSS) 2023, and Bharatiya Sakshya Adhiniyam (BSA) 2023. These have replaced IPC, CrPC, and the Indian Evidence Act respectively from 1 July 2024. Most state judiciary papers in 2026 will draw 25–35% of their criminal-law questions from these new codes. This cheat sheet, structured by mapping changes, structural shifts, and probable question patterns, is your final-stretch tool.

1. Why the New Criminal Laws Now Dominate Every Judiciary Paper

The three Sanhitas are not merely renamed colonial statutes — they restructure offences, redefine procedure, and grant statutory recognition to electronic evidence. The Bihar Judicial Service 2026 notification (Advt. 12/2026) explicitly lists BNS, BNSS, and BSA as core subjects. Madhya Pradesh’s 150-MCQ Prelims paper now allocates an estimated 18–22 questions to criminal codes alone, and Allahabad High Court’s draft proposal for the upcoming UP PCS-J revision retains heavy weightage on procedural reforms. The pattern across recent Assam, Rajasthan, and Haryana Mains papers confirms one thing: direct section-quoting questions are rising, especially comparative mapping (e.g., “Section X of IPC corresponds to Section Y of BNS”). Aspirants who can quote section numbers without hesitation will outscore those who only “understand the concept.”

2. BNS — Section-by-Section Mapping You Must Memorise

The BNS contains 358 sections, down from IPC’s 511. Examiners love deletion-and-renumbering trivia. The most probable question hooks are:

• Murder: IPC Section 302 → BNS Section 103. Punishment unchanged (death or life imprisonment).
• Culpable homicide not amounting to murder: IPC 304 → BNS Section 105.
• Causing death by negligence: IPC 304A → BNS Section 106 (now with enhanced punishment for hit-and-run plus failure to report — up to 10 years).
• Mob lynching: Codified for the first time under BNS Section 103(2) — when 5 or more persons act on grounds of race, caste, sex, language, or personal belief, punishment is death or life imprisonment.
• Sedition repealed and replaced: The new Section 152 creates the offence of “acts endangering sovereignty, unity and integrity of India” — note this is narrower and offence-specific, not the colonial sedition standard.
• Terrorism: Statutorily defined for the first time in general criminal law under Section 113, importing UAPA’s framework.
• Organised crime: New Section 111 — earlier covered only under state-specific MCOCA-type laws.
• Snatching: Carved out as a distinct offence under Section 304, separate from theft and robbery.
• Cheating: IPC 420 → BNS Section 318.
• Rape: IPC 375/376 → BNS Sections 63–70; gang rape on a minor below 18 now attracts the death penalty.

3. BNSS — The Procedural Revolution You Cannot Ignore

BNSS contains 531 sections against CrPC’s 484. The changes are heavily procedural and tech-forward — exactly the kind of material that yields a steady 8–10 MCQs per paper.

• Zero FIR with statutory backing: Section 173 mandates registration of FIR in cognizable offences irrespective of jurisdiction, with mandatory transfer within 15 days.
• e-FIR: First information may be given electronically, with the proviso that it must be signed within three days. This is a frequent factual question.
• Time-bound investigation in sexual offences: Section 193(3) — investigation in offences against women and children must be completed within 2 months.
• Police custody: Section 187 — the 15-day police custody period may now be sought in fragmented manner across the first 40/60 days of judicial custody, a major departure from CrPC’s restrictive interpretation in CBI v. Anupam Kulkarni.
• Trial in absentia: Section 356 permits trial of proclaimed offenders in absentia after a 90-day waiting period — entirely new.
• Mandatory videography: Section 105 requires search and seizure to be videographed; this is admissible as evidence.
• Forensic visits mandatory: For offences punishable with 7+ years, forensic team visit to the scene is compulsory under Section 176(3).
• Summary trials expanded: Now cover offences punishable up to 3 years (earlier 2 years) under Section 283.
• Judgment timelines: Judgment to be pronounced within 45 days of conclusion of arguments; charge framing within 60 days of first hearing — see Sections 258 and 251.

4. BSA — Why Electronic Evidence is the New Section 65B

BSA retains 170 sections, broadly mirroring the Indian Evidence Act, but with three substantive upgrades:

• Electronic records as primary evidence: Section 57 expressly treats electronic and digital records as primary evidence. The Section 65B (IEA) certificate regime is preserved but expanded under BSA Section 63, with a clearer schedule for certificate format.
• Expanded definition of “document”: Now includes electronic and digital records, communications stored on semiconductor memory, voice mail, server logs, smartphones, and locational data — see BSA Section 2(1)(d).
• Joint trials and confessions: Section 30 of IEA → BSA Section 24, with clarified illustrations on the value of co-accused confessions.
• Expert opinion: Expanded to include digital forensics, cyber experts, and DNA analysts under Section 39.

5. The Comparative Question Pattern: How Examiners Test the New Codes

Across 2025 mock test analyses and recent state PYQs, four question archetypes dominate:

1. Direct mapping MCQs: “Section 420 IPC corresponds to which section of BNS?” — pure recall. Targets weak preparation.
2. Conceptual shift MCQs: “Which of the following is a new offence introduced under BNS that did not exist under IPC?” Options typically include mob lynching, organised crime, terrorism, snatching.
3. Procedural timeline MCQs: “Under BNSS, judgment must be pronounced within how many days?” — pure factual.
4. Mixed-statute MCQs: Combine BNS + BNSS + BSA — for example, “X commits theft and FIR is filed electronically; under which provision and which sanhita?” Tests integration.

Mains essay questions in MP, Rajasthan, and Bihar are also testing critical comment: “Discuss whether the BNS adequately addresses cyber offences” or “Examine the constitutional validity of trial in absentia under Section 356 BNSS.” Read at least three SCC Online or LiveLaw editorials per code to develop a defensible position.

6. The Smart 24-Day Revision Plan for Bihar Aspirants

If you are sitting the BPSC 33rd Bihar Judicial Service Prelims on 3 June 2026, here is a tight, realistic plan from today (10 May 2026):

• Days 1–5 (10–14 May): Complete one full reading of BNS — chapter-wise, with the IPC-BNS mapping table open. Target 70 sections per day.
• Days 6–10 (15–19 May): BNSS first reading. Focus on procedural timelines, custody provisions, and the new chapters on electronic records and trial in absentia.
• Days 11–13 (20–22 May): BSA in entirety. It is the shortest of the three and the highest yield per section.
• Days 14–18 (23–27 May): Two daily MCQ sets — one mixed, one criminal-law-only. Aim for 50 questions per day, with full solution review.
• Days 19–22 (28–31 May): Two full-length sectional mocks. Use them diagnostically, not for ego.
• Days 23–24 (1–2 June): Revise only your error log. Sleep 7 hours. Reach the centre 90 minutes early on 3 June.

7. Common Mistakes That Cost Aspirants 8–10 Marks

Across the 2024 and 2025 judiciary exam cycles, three recurring errors stand out:

• Confusing BNS section numbers with IPC: Especially Section 103 (BNS murder) being mistaken for Section 103 IPC (right of private defence). Always cross-tag.
• Treating “Zero FIR” as new: It existed in practice and judicial precedent earlier; what is new is statutory recognition under BNSS Section 173.
• Forgetting the 1 July 2024 enforcement date: Offences committed before 1 July 2024 continue to be tried under IPC/CrPC/IEA. This temporal cut-off is a favourite trick question.

FAQ

Q1. Are the new criminal laws — BNS, BNSS, BSA — applicable to the 33rd BPSC Bihar Judicial Service 2026 exam?

Yes. The 33rd Bihar Judicial Service Prelims notification confirms that BNS, BNSS, and BSA replace IPC, CrPC, and the Indian Evidence Act respectively. Candidates must prepare from the new codes for both Prelims and Mains.

Q2. Will offences that occurred before 1 July 2024 be tested under BNS or IPC?

Offences committed before 1 July 2024 continue to be governed by the old codes — IPC, CrPC, and IEA. Offences from 1 July 2024 onwards fall under BNS, BNSS, and BSA. Exam questions commonly test this transitional rule.

Q3. How many sections do the new criminal codes contain?

BNS has 358 sections (down from IPC’s 511), BNSS has 531 sections (up from CrPC’s 484), and BSA retains 170 sections (broadly comparable to the Indian Evidence Act’s 167).

Q4. What is the most high-yield topic across BNS, BNSS, and BSA for judiciary prelims 2026?

Section-mapping between old and new codes is the highest-yield topic, followed by procedural timelines under BNSS (custody, charge-framing, judgment), and the treatment of electronic records as primary evidence under BSA Section 57.

Q5. Are mock tests available for the new criminal laws specifically?

Yes — most reputable judiciary preparation platforms now offer dedicated BNS-BNSS-BSA mock test series. Pair these with bare-act reading and previous year analysis for maximum retention.

Final Word

The new criminal laws are no longer a “topic” — they are the spine of judiciary prelims and mains in 2026. Map every IPC section you have ever revised to its BNS counterpart, drill the BNSS timelines, and treat BSA Section 57 like an old friend. Walk into the 3 June Bihar Judicial Service centre — and every subsequent state judiciary centre this year — knowing that the section numbers, the timelines, and the new offences are the difference between a cut-off miss and a cut-off clear.
