On 1 July 2024, India turned a historic page in its legal history. Three colonial-era statutes that had governed criminal justice for over 150 years — the Indian Penal Code (IPC), 1860, the Code of Criminal Procedure (CrPC), 1973, and the Indian Evidence Act, 1872 — were replaced by three new laws. For law students, judiciary aspirants and teachers, this is the single most important development to master today. This guide explains what changed, what stayed the same, and how to prepare.

What Changed on 1 July 2024

The three new criminal laws received the President’s assent on 25 December 2023 and came into force on 1 July 2024:

• Bharatiya Nyaya Sanhita (BNS), 2023 replaces the Indian Penal Code, 1860 — the substantive law defining offences and punishments.
• Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023 replaces the Code of Criminal Procedure, 1973 — the procedure for investigation, arrest, bail and trial.
• Bharatiya Sakshya Adhiniyam (BSA), 2023 replaces the Indian Evidence Act, 1872 — the law of evidence.

BNS, BNSS and BSA at a Glance

• BNS has 358 sections across 20 chapters (the IPC had 511 sections).
• BNSS has 531 sections (the CrPC had 484).
• BSA has 170 sections (the Evidence Act had 167).

Fewer sections does not mean fewer offences — it reflects the consolidation of overlapping provisions and the removal of obsolete ones.

Key Changes Every Student Should Know

• Zero FIR — an FIR can be registered at any police station regardless of jurisdiction (BNSS Section 173).
• Electronic records — e-FIR, e-charge sheets and electronic evidence are formally recognised, with digital records treated as primary proof.
• Community service is introduced as a punishment for certain petty offences for the first time.
• Sedition as it existed under the IPC is removed; a new provision addresses acts endangering the sovereignty, unity and integrity of India.
• Mandatory forensics for offences punishable with seven years or more, plus time-bound investigation and trial.
• Trial in absentia of proclaimed offenders becomes possible.

Old Cases vs New Cases: Which Law Applies?

A common myth is that pending IPC cases are wiped out. They are not. The transitional provisions preserve them: if an offence was committed before 1 July 2024, the IPC, CrPC and Evidence Act continue to apply; offences on or after that date fall under the BNS, BNSS and BSA. Courts and practitioners will therefore work with both the old and new codes side by side for years — which is exactly why understanding the mapping between them matters.

What This Means for Law Students & Judiciary Aspirants

The Bar Council of India has directed universities to update their syllabi, and judicial services, civil services and law-enforcement examinations now test the new laws. Practical advice:

• Study the new statutes as your primary text, but keep the IPC/CrPC/Evidence Act for context — much settled case law still explains the underlying principles.
• Learn the section mapping (for example, IPC 302 → BNS 103) so you can move between old judgments and new provisions.
• Focus on the genuinely new offences and procedures (digital evidence, Zero FIR, fixed timelines) — these are favourite examination topics.
