Criminal Law Research Topics under BNS, BNSS and BSA

Criminal law research in India now begins with the Bharatiya Nyaya Sanhita (BNS), the Bharatiya Nagarik Suraksha Sanhita (BNSS) and the Bharatiya Sakshya Adhiniyam (BSA), all in force from 1 July 2024. The strongest topics test a specific new provision against old case law, constitutional rights or ground realities, and the list below gives you such topics, sorted by statute and theme.

Substantive offences under the BNS

• Section 152 BNS: The IPC’s sedition provision is gone, but Section 152 punishes acts endangering the sovereignty, unity and integrity of India. Does it meet the standard of Kedar Nath Singh (1962), or does it widen the net?
• Organised crime, Section 111: Is a general code the right home for an offence borrowed from special laws like MCOCA? A comparative study of definitions and evidence thresholds.
• Petty organised crime, Section 112: Does the offence risk criminalising poverty-linked street crime?
• Terrorist act, Section 113: With UAPA still in force, who decides which law to invoke, and should that choice be reviewable?
• Mob lynching, Section 103(2): Does a separate murder category for groups of five or more on grounds such as caste or community change charging and conviction patterns?
• Section 69 BNS: Sexual intercourse by deceitful means or a false promise to marry. Gender protection or a new route to criminalise failed relationships?
• Marital rape exception: Exception 2 to Section 63 survives in the BNS. How do the pending challenges frame the issue, and what would a statutory reform look like?
• Community service: Section 4(f) adds community service as a punishment. Which agencies design and supervise it, and is there any data yet?
• Gender-neutral offences: Which BNS offences became gender neutral and which did not? A mapping of gaps for male and transgender victims.

Procedure under the BNSS

• Police custody, Section 187: Custody of up to 15 days can now be taken in parts during the first 40 or 60 days. Does staggered custody undercut the liberty safeguards in CBI v. Anupam J. Kulkarni (1992)?
• Undertrial release, Section 479: First-time offenders can be released after one-third of the maximum sentence. Why does implementation lag, and what role should jail superintendents play?
• Trial in absentia, Section 356: Can a proclaimed offender be tried and convicted without being present, consistent with Article 21 and the ICCPR?
• Zero FIR and e-FIR, Section 173: Has registration become easier for women and remote complainants? An empirical study design using one State’s data.
• Preliminary enquiry, Section 173(3): For offences punishable with three to seven years, does the 14-day enquiry window dilute Lalita Kumari (2013)?
• Videography of search and seizure, Section 105: What happens to evidence when recording is missing?
• Forensics, Section 176(3): Forensic experts must visit crime scenes for offences punishable with seven years or more. Is there enough capacity at district level?
• Timelines: Do the BNSS deadlines for charge, judgment and investigation have any consequence when breached?
• Electronic proceedings, Section 530: Virtual trials and summons by electronic means. Fair trial and digital divide concerns.

Evidence under the BSA

• Section 63 BSA: The certificate for electronic records now has a prescribed format in the Schedule, signed by the person in charge and an expert. Does this settle the questions left after Arjun Panditrao Khotkar (2020)?
• Electronic records as primary evidence: How should courts treat cloud data, WhatsApp chats and CCTV footage now?
• Deepfakes as evidence: What authentication standards should courts apply to audio and video that may be synthetic?
• Confessions and digital interrogation: Do Sections 22 and 23 BSA adequately guard against coercion when statements are recorded on devices?

Cross-cutting and empirical topics

• Pending cases under old law: how are courts handling transition under Section 531 BNSS?
• Translating the new codes: does the use of Hindi titles affect understanding among litigants in non-Hindi States?
• Police training on the new codes: a survey design for one district.
• Victim rights in the BNSS: information on progress of investigation within 90 days. Is it followed?
• Criminal law and AI: should predictive policing tools be regulated under the BNSS or a separate law?

How to narrow a criminal law topic

1. Start from one section. Compare it with the IPC or CrPC equivalent in a two-column table. Note what changed in words, punishment and procedure.
2. Add one test. Constitutional (Article 14, 20, 21), comparative (UK or another common law system) or empirical (case outcomes in one court).
3. Use a research question. For example: “Does Section 187(3) BNSS allow police custody beyond the first 15 days of remand, and if so, is that consistent with Article 21?” See framing research questions.
4. Keep claims proportionate. Two years of practice is limited data. Say what your evidence can and cannot show.

• The 2023 report of the Parliamentary Standing Committee on Home Affairs on the three Bills.
• Supreme Court and High Court judgments interpreting the new codes (search by section number and “BNSS” on official sites).
• NCRB “Crime in India” and “Prison Statistics India” for data.

Frequently asked questions

Should I still cite IPC and CrPC cases?

Yes, where the new provision is substantially the same. Explain the correspondence (for example, IPC Section 124A and BNS Section 152) and note any differences in wording.

When did BNS, BNSS and BSA come into force?

All three came into force on 1 July 2024. Offences committed before that date continue under the old law, subject to the savings clauses.

Is there enough case law on the new codes for a paper?

There is a growing body of High Court decisions and some Supreme Court rulings. Many good papers are doctrinal comparisons or small empirical studies rather than case-law surveys.
