BNSS vs CrPC: Major Changes Explained

A Comprehensive Guide to India's New Criminal Procedure Code — All Important Changes, Section-by-Section Comparison, and What Every Citizen Must Know

Updated: August 2026 | Reading Time: 25 Minutes | Author: Law Zone Editorial Team

Introduction: The End of an Era

For over five decades, the Code of Criminal Procedure, 1973 (CrPC) served as the backbone of India's criminal justice system. It governed everything from how the police register a complaint to how a trial concludes in court. But let's be honest — a law written in 1973 was simply not equipped to handle the complexities of 21st-century India. Cybercrimes, organized crime, digital evidence, and the massive backlog of pending cases were realities that the old CrPC struggled to address.

Enter the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) — a landmark legislation that came into force on July 1, 2024, replacing the CrPC entirely. The name itself tells a powerful story. While "CrPC" was a dry, colonial-era acronym, "Bharatiya Nagarik Suraksha Sanhita" literally translates to "Indian Citizen Protection Code." This shift in nomenclature signals a fundamental change in philosophy — from a procedure-focused colonial law to a citizen-centric, protection-oriented framework that puts the rights and safety of ordinary Indians at its core.

Key Takeaway: The BNSS is not merely a renumbered CrPC. It represents a conscious effort to remedy the procedural gaps of the old code by statutorily integrating technology, mandating stricter timelines, and introducing modern concepts like compulsory forensics and trial in absentia.

The BNSS doesn't just tinker around the edges. It introduces sweeping reforms across investigation, arrest, bail, trial procedures, and the use of technology in justice delivery. It aims to make the system faster, more transparent, more tech-savvy, and more responsive to the needs of victims while maintaining a delicate balance with the rights of the accused. In this article, we'll walk you through every major change, every new power, and every safeguard introduced by this transformative law — in simple, human language that anyone can understand.

If you are new to the new criminal laws, we recommend reading our detailed guide on the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023 for a foundational understanding before diving into the specific comparisons below.

1. Structural Reorganization: From 484 to 531 Sections

One of the most immediate differences between the CrPC and the BNSS is the structural overhaul. The CrPC consisted of 37 Chapters, 484 Sections, and 2 Schedules. The BNSS expands this to 39 Chapters, 531 Sections, and 2 Schedules. This increase is not due to added complexity, but rather to a better reorganization of provisions. Clauses that were previously clubbed together have been separated for clarity.

For example, provisions related to FIRs, arrests, and bail have been categorised more systematically, enabling easier navigation for law enforcement officers and legal practitioners. The BNSS also removes some redundant provisions:

• Metropolitan Magistrates: The distinction between Metropolitan Magistrates and Judicial Magistrates has been eliminated, bringing uniformity across urban and rural areas.
• Judicial Magistrate of Third Class: This post has been removed to streamline the court hierarchy.
• Assistant Sessions Judge: This position has also been omitted to simplify the judicial structure.
• Section 144-A of CrPC: The power to prohibit carrying of arms in processions has been deleted as redundant.

Learn more about the court structure under the new law in our article on Section 9 of BNSS — Courts of Judicial Magistrates.

2. The Digital Revolution: Technology Integration

A glaring gap in the CrPC was its silence on modern technology. While courts had permitted electronic processes through judicial orders, especially post-COVID-19, there was no uniform statutory provision. The BNSS changes this fundamentally. It explicitly allows for trials, inquiries, service of summons, and recording of evidence to be conducted electronically, providing a clear legal foundation that was absent in the CrPC.

2.1 Electronic FIRs (e-FIRs)

Under Section 173 of the BNSS, the concept of electronic FIRs has been formally recognized. The law mandates that information regarding cognizable offences received electronically must be reduced to writing and signed by the informant within three days. This provision legalises the e-FIR mechanism, ensuring that complaints can be registered remotely without physical presence at a police station.

Practical Impact: Victims of cybercrimes, which frequently transcend geographical boundaries, can now register complaints from anywhere. This is particularly critical given the borderless nature of digital offences.

2.2 Zero FIR Becomes Statutory

The concept of a "Zero FIR" was a judicial innovation, most notably affirmed by the Supreme Court in Lalita Kumari v. Govt. of U.P., to ensure victims were not turned away. However, it was not written into the CrPC's Section 154. The BNSS rectifies this. Section 173(1) of the BNSS now gives this crucial judicial precedent a statutory home, making it a legal mandate for every police officer to register an FIR upon receiving information about a cognizable offence, regardless of their territorial jurisdiction.

2.3 Electronic Summons and Warrants

Section 63 of the BNSS revolutionizes the form of summons. While Section 61 of CrPC only recognized physical, paper-based documents, Section 63 BNSS adds the revolutionary clause for electronic communication. Summons can now be served via encrypted digital communication with digital signature or seal image.

Our detailed analysis of Section 63 of BNSS — Form of Summons explains how this impacts every citizen who receives court communications.

2.4 Mandatory Videography of Search and Seizure

Under the CrPC, search and seizure procedures lacked a mandatory audio-visual recording requirement, often leading to disputes. Section 105 of the BNSS introduces a crucial new safeguard: the videography of any search and seizure is now mandatory. The proviso to Section 185(2) adds that such recording shall preferably be made by a mobile phone.

2.5 Digital Evidence Collection

While the Evidence Act dealt with admissibility, the CrPC was limited in its scope for collecting digital evidence. Section 311A of the CrPC empowered a Magistrate to order a person to provide specimen signatures or handwriting. The corresponding Section 349 of the BNSS expands this power significantly, allowing magistrates to also order the collection of finger impressions and voice samples, even from a person not under arrest.

3. Mandating Speed: Strict Timelines for Justice

The CrPC had some timelines, like the 60/90 day period for filing a charge sheet under Section 167. However, many stages lacked strict statutory deadlines, contributing to the infamous backlog of Indian courts. The BNSS introduces a culture of speed by making timelines mandatory across the board.

Procedure	CrPC Position	BNSS 2023 Mandate	BNSS Section
Investigation Completion	No fixed timeline; investigations could drag on for years	Must be completed within 90 days, extendable to 180 days for serious offences	Section 193
Charge Framing (Sessions Court)	No strict timeline prescribed after first hearing	Must frame charges within 60 days from first hearing on charges	Section 228
Judgment Delivery	No statutory deadline; judgments often delayed indefinitely	Must be pronounced within 30 days of completion of arguments (extendable to 45/60 days with recorded reasons)	Section 258
Victim Updates	No provision requiring police to update victims	Victim/informant must be informed of investigation progress within 90 days	Section 193(3)
Medical Report (Rape Cases)	No fixed deadline	Medical practitioner must submit report within 7 days of examination	Section 52
Bail Application Disposal	No strict timeline	Magistrates must decide bail applications within 7 days	Section 480
Distribution of Proceeds of Crime	No specific timeline	Must be distributed within 60 days of court order	Section 107

Why This Matters: These timelines, if enforced, could dramatically speed up the justice delivery system and reduce the current backlog of millions of pending cases. The culture of delay that plagued the old system now faces statutory resistance.

4. Arrest Procedures: New Rules, New Safeguards

The moment of arrest is one of the most critical interactions between the state and the citizen. The BNSS introduces several important changes to how arrests are conducted, aiming to make the process more humane yet effective. For a deeper understanding of your rights during arrest, read our guide on Can Police Arrest You Without a Warrant?

4.1 Mandatory Recording of Reasons

For offences punishable with imprisonment of seven years or more, the police must now record reasons for arrest in writing before making the arrest. This is a significant safeguard against arbitrary arrests. The officer must justify why arrest is necessary, and this record becomes subject to judicial scrutiny.

4.2 Notice Before Arrest

The BNSS consolidates the old Sections 41 and 41A of CrPC into Section 35, incorporating the Arnesh Kumar safeguards directly into the statutory text. The new law adds additional protections, including special safeguards for the elderly and infirm. Our article on Arnesh Kumar v. State of Bihar (2014) explains how these landmark guidelines have been preserved and strengthened.

4.3 Handcuffing: A Controversial New Power

Perhaps one of the most debated provisions of the BNSS is Section 43(3), which for the first time gives police the statutory power to use handcuffs. Under the old CrPC, there was no specific provision about handcuffs, and the Supreme Court had consistently held that handcuffing should be an exception, not the rule.

The BNSS now permits handcuffs for:

• Habitual or repeat offenders
• Persons who have escaped from custody
• Organized crime, terrorist acts, drug-related crimes
• Murder, rape, acid attack, human trafficking
• Offences against the State
• Economic offences

Constitutional Concern: Critics argue that this provision could lead to routine handcuffing and violates the dignity of the accused, contrary to Supreme Court precedents. The inclusion of "economic offences" in this list has particularly raised eyebrows, as white-collar criminals are typically not a flight risk.

4.4 Medical Examination

The CrPC allowed medical examination of the accused in certain cases, including rape cases, but only on the request of at least a sub-inspector level police officer. The BNSS provides that any police officer can request such an examination, potentially streamlining the process but also raising concerns about oversight.

5. Police Custody: The 15-Day Rule Reimagined

This is one of the most significant and controversial changes in the BNSS. Under the old CrPC, if a person was arrested, they had to be produced before a magistrate within 24 hours. The magistrate could then authorize police custody for up to 15 days, followed by judicial custody for up to 60 or 90 days depending on the offence. The general rule was that police custody should be taken in the first 15 days of remand.

CrPC, 1973 (Old Law)

Police custody of 15 days could only be granted within the first 15 days of remand. Once the accused was sent to judicial custody, they could not be taken back into police custody.

BNSS, 2023 (New Law)

Police custody of 15 days can now be authorized in whole or in parts at any time during the initial 40 or 60 days out of the total 60 or 90 days of judicial custody.

Section 187(2) of the BNSS fundamentally alters this. It allows the police to seek the total 15 days of custody in parts, at any time during the initial 40 or 60 days of detention. This means police can request to take an accused back into police custody even after they've been in judicial custody for several weeks.

Critical Concern: This fragmented custody provision could be used to deny bail to accused persons for extended periods. If the police haven't exhausted their 15 days of custody, they can argue that the accused needs to be taken back for further interrogation, potentially keeping them in detention longer. The Standing Committee on Home Affairs had recommended that the interpretation of this clause be clarified.

6. Mandatory Forensic Investigation: Science Meets Justice

This is one of the most revolutionary departures from the previous regime. The CrPC had no provision that made forensic investigation a compulsory part of the process. It was left to the discretion of the investigating officer. Section 176(3) of the BNSS introduces a game-changing mandate:

For any offence punishable with seven years of imprisonment or more, a forensic expert must visit the crime scene to collect evidence, and the entire process must be recorded via videography on mobile phone or any other electronic device.

This transforms the investigation of serious crimes from a confession-driven model to a modern, evidence-based one. If a state does not have forensic facilities, it must utilize such facilities in another state until the required infrastructure is developed.

Timeline for Implementation: This provision will be effective from the date notified by the State Government within a period of five years, giving states time to develop the requisite machinery.

The benefits are manifold:

• More reliable trials based on scientific evidence
• Stronger prosecution with forensic backing
• Reduced wrongful arrests and convictions
• Enhanced transparency through mandatory videography

7. Victim-Centric Approach: Giving Voice to the Vulnerable

The CrPC was primarily concerned with the prosecution and the accused. The BNSS shifts this paradigm by introducing robust victim-centric provisions:

7.1 Right to Information

Under Section 193(3) of the BNSS, the police must inform the victim or informant of the progress of the investigation within 90 days. This closes a long-standing gap where victims were often left in the dark about their own cases.

7.2 Participation in Proceedings

Victims of specific crimes may now be heard when charges are being framed. This ensures that the victim's perspective is considered at crucial stages of the trial.

7.3 Audio-Video Recording of Statements

Statements of victims, particularly in sexual offences, must be recorded through audio-video means. In sexual offences, statements must be recorded by women officers, providing a more sensitive environment for survivors.

7.4 Timely Compensation

The State is required to give victims interim relief in a timely manner, ensuring that victims do not suffer financially while waiting for the conclusion of lengthy trials.

7.5 Witness Protection

Improved witness protection measures prevent intimidation and ensure fairness for survivors who might otherwise be too afraid to testify.

8. Trial in Absentia: Justice Without Borders

For the first time in India's general criminal procedure law, the BNSS introduces trial in absentia — the ability to conduct a trial and pronounce judgment even when the accused is not present. Section 356 of the BNSS applies specifically to proclaimed offenders.

Under Section 299 of the CrPC, only the recording of evidence against an absconding accused was permitted, but the trial could not conclude. The BNSS takes a massive leap forward by allowing a full trial to proceed and a judgment to be pronounced in the absence of a proclaimed offender.

Safeguards Built Into the Law:

• The accused must first be declared a proclaimed offender through a rigorous process
• Two consecutive warrants must have been issued within a 30-day interval
• The court cannot commence the trial until 90 days have lapsed from the date of framing charges
• A notice must be published in a national or local newspaper
• Relatives or friends must be informed
• Information must be displayed at the accused's house and local police station
• If the accused is not represented, the court must provide a state-funded lawyer

This provision aims to prevent the common problem of trials getting stalled indefinitely because the accused has fled, while ensuring that the accused's rights are not completely sacrificed.

9. Sentencing Powers and Community Service

The BNSS introduces significant changes regarding the sentencing power of Magistrates and adds a new form of punishment:

Aspect	CrPC, 1973	BNSS, 2023
JMFC Fine Power	Maximum fine up to Rs. 10,000	Maximum fine up to Rs. 50,000 + Community Service option
JMSC Fine Power	Maximum fine up to Rs. 5,000	Maximum fine up to Rs. 10,000 + Community Service option
Consecutive Sentences Cap	Maximum aggregate of 14 years	Maximum aggregate of 20 years
Community Service	No provision	Introduced as punishment for petty offences
Concurrent vs. Consecutive	Presumption of consecutive if not mentioned	Court must consider gravity and explicitly state the decision

The introduction of community service as a specific punishment for several petty offences is a reformative sentencing option that was not part of the old code. This reduces burden on courts, provides quick resolution for petty offences, and encourages social responsibility.

10. Detention, Bail, and Release of Undertrials

The BNSS makes critical changes to how undertrials are treated, particularly regarding default bail and maximum detention periods.

10.1 Default Bail Restrictions

Under the CrPC, if an accused has spent half of the maximum period of imprisonment in detention, they must be released on personal bond (except for offences punishable by death). The BNSS adds two significant exclusions:

• Offences punishable by life imprisonment are now excluded (previously only death-punishable offences were excluded)
• Persons against whom proceedings are pending in more than one offence are excluded

Impact: As many cases involve charges under multiple sections, this may severely limit the availability of default bail for a large number of undertrials.

10.2 Maximum Detention Period

Section 436A CrPC has been replaced by Section 479 of the BNSS. The one-half and one-third rules for release of undertrials now explicitly bar release where investigation, inquiry, or trial is pending against the undertrial in more than one offence or in multiple cases. Read our comprehensive guide on Maximum Detention of an Undertrial and Release under Section 479 BNSS.

10.3 Maintenance Provisions

The maintenance provisions under the old Section 125 CrPC have been renumbered as Section 144 BNSS, with subsequent sections also renumbered. The substantive law remains almost unchanged. Learn more in our article on Maintenance Under Section 125 CrPC (Section 144 BNSS).

11. Witness Attendance and Protection

The BNSS updates provisions regarding witness attendance during investigations. Under Section 179, the investigating officer can call any person acquainted with the facts of the case.

CrPC Exemptions (Section 160)

Men below 15 years or above 65 years were exempted from appearing at any place other than their residence.

BNSS Exemptions (Section 179)

Men below 15 years or above 60 years are exempted, and this exemption now also extends to persons with acute illness.

Importantly, a new proviso allows these exempted persons to voluntarily appear at the police station if they choose to do so, respecting the autonomy of vulnerable witnesses while ensuring their testimony isn't lost.

12. Summary Trials and Plea Bargaining

Chapter 22 of the BNSS deals with summary trials. The new provision has a legal mandate to try the listed offences as per the summary procedure, as Section 283 of BNSS uses the word "shall" instead of "may" which was used in the old CrPC.

Key changes in summary trials:

• The value of property subject matter of listed offences increased from Rs. 2,000 to Rs. 20,000
• Magistrates may try summarily offences not punishable with death, life imprisonment, or imprisonment exceeding 3 years (previously 2 years)
• The decision to try a case summarily under Section 283(2) is not appealable

14. Challenges and Controversies

While the BNSS represents a paradigm shift, it is not without its controversies and implementation challenges:

14.1 Expanded Police Powers

The altered police custody provisions, statutory handcuffing power, and the ability to seek custody in fragments have raised serious concerns about potential misuse. Legal experts worry that these provisions could be used to extract confessions or deny bail strategically.

14.2 Infrastructure Gap

The success of the BNSS depends heavily on implementation:

• Do police stations have the infrastructure for electronic FIRs?
• Are forensic labs equipped to handle mandatory investigations?
• Will courts have the resources to meet strict timelines?
• Is digital literacy sufficient for electronic summons and evidence?

14.3 Overlap with Existing Laws

The overlap with existing laws like the Criminal Procedure (Identification) Act, 2022, creates potential confusion. The BNSS allows evidence collected by retired or transferred investigating officers to be presented by their successors, which violates normal rules of evidence regarding cross-examination of the document's author.

14.4 Property Attachment Concerns

The powers to attach property from proceeds of crime under the BNSS do not have the same safeguards provided in the Prevention of Money Laundering Act, raising concerns about due process.

14.5 Training and Awareness

Proper implementation requires massive training for police and judiciary, infrastructure for digital courts, and widespread public awareness. Without these, the law's promise may remain on paper.

15. Conclusion: A New Philosophy of Justice

The Bharatiya Nagarik Suraksha Sanhita, 2023, represents a paradigm shift in India's criminal justice system. It brings the law into the digital age, emphasizes forensic science, protects victims' rights, and aims to deliver speedy justice. The introduction of community service, mandatory forensic investigations, electronic proceedings, and trial in absentia are genuinely progressive steps that align India's procedural law with 21st-century realities.

However, the law is not without its controversies. The expanded police custody provisions, the restrictions on default bail for multiple charges, the statutory power to use handcuffs, and the potentially weaker safeguards for property attachment are areas that will likely be tested in courts for years to come.

The Bottom Line: The BNSS is not just a new law — it's a new philosophy of justice, one that seeks to balance the rights of the accused with the rights of victims, the needs of law enforcement with the protections of civil liberties, and the traditions of the courtroom with the possibilities of technology.

What is clear is that India has taken a bold step toward modernizing its criminal justice system. The success of this transformation will ultimately depend not just on the text of the law, but on how faithfully it is implemented on the ground — in police stations, forensic labs, and courtrooms across the nation. For citizens, understanding these changes is the first step toward exercising their rights effectively in the new legal landscape.
