On 1st July 2024, India did something it had not done since independence: it replaced the three pillars of its criminal justice system in one stroke. The colonial-era Indian Penal Code, Code of Criminal Procedure, and Indian Evidence Act gave way to three new laws. For every citizen, lawyer, and business, this is not a cosmetic rename - it changes how crimes are defined, how police investigate, and how courts weigh evidence. Here is what actually changed, in plain English.
The three new codes
- Bharatiya Nyaya Sanhita (BNS), 2023 - replaces the Indian Penal Code (IPC), 1860. This is the substantive law: it defines crimes and their punishments.
- Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023 - replaces the Code of Criminal Procedure (CrPC), 1973. This is the procedural law: arrests, investigation, bail, and trial.
- Bharatiya Sakshya Adhiniyam (BSA), 2023 - replaces the Indian Evidence Act, 1872. This governs what evidence a court can consider and how.
Why the overhaul happened
The stated aim was to shift the philosophy of the system from punishment to justice, to shed colonial-era language and offences, and to bring criminal procedure into the digital age. Whatever one's view of how well it succeeds, the practical reality is that the section numbers everyone knew for generations - 302 for murder, 420 for cheating - have changed, and a transition period of overlapping cases is inevitable.
What changed in substantive law (BNS)
- Familiar offences, new numbers. Murder, cheating, theft, and the rest survive but are renumbered and regrouped, with offences against women and children brought together more coherently.
- Terrorism defined in the general code. For the first time terrorism is defined within the main penal law rather than only in special statutes.
- Organised crime and 'petty' organised crime are now distinct offences.
- Community service is introduced as a form of punishment for certain minor offences - a genuinely new concept in Indian penal law.
- Mob lynching based on identity markers is recognised as a specific offence carrying severe punishment.
What changed in procedure (BNSS)
- Zero FIR - you can register an FIR at any police station regardless of where the offence occurred, and it is then transferred to the right jurisdiction.
- e-FIR - certain complaints can be registered electronically, reducing the friction of physically reaching a police station.
- Time-bound steps - the law sets deadlines for stages such as filing the charge sheet and pronouncing judgment, aimed at curbing endless delay.
- Mandatory forensics - forensic investigation is required for serious offences, with videography of search and seizure.
- Victim rights - victims are entitled to be kept informed of the progress of the investigation.
What changed in evidence (BSA)
The headline shift is the formal embrace of the digital world. Electronic and digital records - emails, server logs, location data, messages - are now squarely recognised as primary evidence, with rules for their admissibility. This matters enormously for modern investigations and for businesses, where most records are now electronic rather than paper.
For ordinary citizens the most useful practical change is the Zero FIR and e-FIR: you no longer have to be in the 'right' police station to start the legal process - jurisdiction is sorted out afterwards.
What it means for businesses
Compliance and finance professionals should pay attention for three reasons. First, offences like cheating and fraud - common in commercial disputes - are renumbered, so contracts, policies, and legal notices that cite old IPC sections need updating. Second, the strong recognition of electronic evidence raises the stakes on data retention, email hygiene, and audit trails. Third, the new organised-crime provisions broaden exposure in cases involving coordinated economic offences.
A practical example
Suppose an employee discovers a fraud and wants to report it, but the relevant branch is in another city. Under the new procedure they can walk into their local police station and register a Zero FIR; it is recorded immediately and transferred to the correct jurisdiction, rather than being turned away. If the case proceeds, the company's emails and server logs - now clearly admissible as electronic evidence under the BSA - can carry the proof, provided the business kept them intact.
Common misconceptions to avoid
- Thinking old cases vanished - offences committed before 1st July 2024 are still tried under the old laws.
- Assuming the crimes themselves changed wholesale - most are renumbered, not abolished.
- Citing IPC section numbers in fresh notices and contracts out of habit.
- Underestimating how central electronic evidence has become.
Frequently asked questions
Do old cases get re-tried under the new laws? No. Offences committed before 1st July 2024 continue under the IPC, CrPC, and Evidence Act; the new codes apply to offences from that date onward.
Is the section for murder really different now? Yes - the offences continue but the numbering has changed, so the famous old section numbers no longer apply to new cases.
Can I really file an FIR anywhere? Yes. The Zero FIR concept, now firmly in the BNSS, lets you register at any police station, with transfer to the proper jurisdiction afterwards.
