TL;DR
The Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, which replaced the Code of Criminal Procedure (CrPC), 1973 on 1 July 2024, retains the broad framework of bail law but introduces several significant changes. The most impactful reform is Section 479, which mandates proactive bail applications by jail superintendents for first-time offenders who have served one-third of their maximum sentence. Anticipatory bail under Section 482 BNSS removes certain restrictive provisos from old Section 438 CrPC, giving courts wider discretion. Default bail timelines remain substantively unchanged but are now read with new mandatory investigation timelines under BNSS.

Detailed Comparison
Bail in Bailable Offences (Section 436 CrPC vs Section 478 BNSS)
What the old law said: Under Section 436 CrPC, when a person accused of a bailable offence was arrested or detained without a warrant, the officer in charge of the police station or the court had a mandatory duty to release the person on bail. If the person was an indigent unable to furnish surety, the court could release on personal bond without sureties.
What the new law says: Section 478 BNSS reproduces this provision with streamlined language. The core obligation — that bail in bailable offences is a matter of right — remains unchanged.
What specifically changed: The language has been modernized, but the substantive right to bail in bailable offences remains absolute and unchanged. No significant departure from the old position.
Practical impact: Minimal for practitioners. The right to bail in bailable offences continues to be enforceable as before.
Maximum Detention and First-Time Offender Bail (Section 436A CrPC vs Section 479 BNSS)
What the old law said: Section 436A CrPC provided that an undertrial prisoner who had served detention for half the maximum period of imprisonment specified for the offence could be released on personal bond, with or without sureties. This applied to all offences except those punishable by death.
What the new law says: Section 479 BNSS significantly expands this framework by introducing:
First-time offender release at one-third: A person who is a first-time offender and has been detained for a period extending up to one-third of the maximum imprisonment for the alleged offence must be released on bail. This is a new entitlement not present in the old law.
Half-period release retained: The existing rule for release after serving half the maximum period continues for all other accused persons (non-first-time offenders).
Jail superintendent's proactive duty: The Superintendent of Jail is now required to proactively apply to the court for bail on behalf of undertrial prisoners who meet the detention thresholds. This shifts the burden from the accused to the prison system.
Multiple-case restriction: An undertrial shall not be released under this provision if investigation, inquiry, or trial in more than one offence or in multiple cases is pending against them. This is a new restriction.
What specifically changed: Three additions — the one-third threshold for first-time offenders, the jail superintendent's mandatory application duty, and the multiple-case exclusion. The death penalty exclusion continues.
Practical impact: This is the single most significant bail reform in BNSS. Defence counsel should proactively track detention periods and invoke Section 479 for first-time offenders. The multiple-case restriction, however, could become a tool for denial — practitioners should be prepared to argue that pending cases must be genuine and not fabricated to defeat bail.
Bail in Non-Bailable Offences — Magistrate's Power (Section 437 CrPC vs Section 480 BNSS)
What the old law said: Section 437 CrPC gave the Magistrate discretion to grant bail in non-bailable offences, subject to several restrictions. Bail could not be granted if there were reasonable grounds to believe the accused was guilty of an offence punishable with death or life imprisonment, unless the accused was under 16, a woman, or sick/infirm.
What the new law says: Section 480 BNSS retains the core framework of Section 437 CrPC with the following modifications:
- The prohibition on anticipatory bail has been expanded to include persons accused of gang rape of a woman below 18 years of age.
- The language has been updated to reference BNS section numbers instead of IPC sections.
What specifically changed: The addition of the gang rape prohibition is the key change. The core discretionary framework for Magistrates remains unchanged.
Practical impact: Practitioners defending persons accused under Section 70(2) BNS (gang rape) must note that Magistrate-level bail is now statutorily barred and applications must be made before the Sessions Court or High Court.
Anticipatory Bail (Section 438 CrPC vs Section 482 BNSS)
What the old law said: Section 438 CrPC allowed the Sessions Court or High Court to grant anticipatory bail to a person who had reason to believe they may be arrested for a non-bailable offence. The section included:
- Proviso to Section 438(1): Power of the police officer in charge to arrest the applicant in cases where interim relief was not granted
- Sections 438(1-A) and 438(1-B): Additional restrictive conditions in certain states
- Sub-section (2): Guiding factors for courts, including nature/gravity of accusation, antecedents of the applicant, and possibility of fleeing justice
What the new law says: Section 482 BNSS retains the core power to grant anticipatory bail but removes several restrictive elements:
- The proviso to Section 438(1) allowing police arrest when interim relief is not granted has been dropped.
- Sections 438(1-A) and 438(1-B) have been excluded.
- The specific guiding factors listed in Section 438(2) have been omitted, leaving courts with broader discretion.
What specifically changed: The removal of restrictive provisos and guiding factors effectively widens the court's discretion. The Chhattisgarh High Court has already held that courts have greater discretionary powers under Section 482 BNSS compared to Section 438 CrPC.
Practical impact: Defence counsel should note that the removal of restrictive provisos strengthens anticipatory bail applications. However, the omission of guiding factors also means courts may develop varying standards. Practitioners should frame applications comprehensively, covering all traditional factors even though they are no longer statutorily mandated.
Special Powers of High Court and Sessions Court (Section 439 CrPC vs Section 483 BNSS)
What the old law said: Section 439 CrPC gave the High Court and Sessions Court special powers to grant bail, including the power to impose any condition, and the power to direct that a person already on bail be arrested and committed to custody.
What the new law says: Section 483 BNSS is substantively identical to Section 439 CrPC, with updated cross-references to BNSS section numbers.
What specifically changed: No substantive change. The superior courts retain their special bail powers.
Practical impact: No change in practice required.
Default Bail (Section 167(2) CrPC vs Section 187(2) BNSS)
What the old law said: Section 167(2) CrPC established the right to default bail if the investigating agency failed to file a chargesheet within the prescribed period — 90 days for offences punishable with death, life imprisonment, or imprisonment of 10 years or more, and 60 days for other offences. This was an indefeasible right recognized by the Supreme Court in multiple decisions.
What the new law says: Section 187(2) BNSS retains these timelines substantively. The 90-day and 60-day limits continue.
What specifically changed: The default bail mechanism remains intact. However, it must now be read alongside the new mandatory investigation timelines under BNSS, which impose separate obligations on investigating agencies to complete investigation and file chargesheets within prescribed periods.
Practical impact: The indefeasible right to default bail continues. Practitioners should track both the default bail clock under Section 187(2) and the new investigation timeline requirements to build comprehensive applications.
New Provisions with No Old Equivalent
Statutory Definitions (Section 2 BNSS)
For the first time, BNSS provides statutory definitions of "bail" (Section 2(1)(b)), "bail bond" (Section 2(1)(c)), and "bond" (Section 2(1)(d)). The CrPC used these terms without defining them, leaving their interpretation to judicial precedent. The codification brings clarity but also limits interpretive flexibility.
Jail Superintendent's Proactive Duty (Section 479(3) BNSS)
The mandatory duty of the jail superintendent to apply for bail on behalf of qualifying undertrial prisoners is entirely new. Under the old law, the burden was entirely on the accused or their counsel to file bail applications.
Abolished Provisions
No bail provision from the CrPC has been entirely abolished. However, the following have been removed or subsumed:
- Section 438(1) Proviso (police power to arrest when interim anticipatory bail relief not granted) — dropped in BNSS
- Section 438(1-A) and 438(1-B) (state-specific restrictive provisions) — dropped in BNSS
- Section 438(2) guiding factors — omitted from Section 482 BNSS, though courts may continue to apply them as a matter of practice
Practical Checklist for Practitioners
- Update all bail petition templates to cite BNSS section numbers (478, 479, 480, 482, 483) instead of CrPC sections
- For first-time offender clients, calculate the one-third detention threshold under Section 479 BNSS and apply proactively
- Note the multiple-case restriction in Section 479 — verify whether pending cases are genuine before conceding this bar
- In anticipatory bail applications, leverage the removal of restrictive provisos under Section 482 to argue for broader court discretion
- Track default bail timelines under Section 187(2) alongside the new investigation deadlines
- For gang rape cases involving victims under 18, note the expanded prohibition on Magistrate-level bail under Section 480
- Engage with jail superintendents to ensure they fulfil their proactive bail application duty under Section 479(3)
- Review all pending bail matters for transitional applicability — cases filed under CrPC but heard after 1 July 2024 must cite BNSS provisions
Recent judicial developments (post-July 2024)
The following cases from the Veritect Legal Intelligence database illustrate how courts are interpreting the new bail provisions in practice:
Suleman Samad v. State of N.C.T. of Delhi (29 January 2025)
Court: Delhi High Court | Judge: Swarana Kanta Sharma | Result: Bail disposed in favour of applicant
The applicant was arrested on 27-03-2023 for alleged sexual assault under IPC Sections 354/354A and the POCSO Act. After more than 1 year and 10 months in judicial custody, jail authorities notified the trial court on 05-12-2024 that one-third of the maximum sentence had been completed and applied for bail under Section 479 BNSS. Despite this, the trial court repeatedly adjourned the matter. The Delhi High Court held that Section 479 BNSS is a statutory right, not discretionary, and the trial court's failure to act constituted an unlawful denial of that right. The Court directed the trial court to dispose of the bail application within seven days.
Significance: This is among the first appellate-level decisions affirming that Section 479 BNSS creates an enforceable statutory entitlement for first-time offenders, not a discretionary benefit.

Tarun Kumar v. Assistant Director, Directorate of Enforcement (20 November 2024)
Court: Delhi High Court | Judge: Jasmeet Singh | Result: Bail granted
The petitioner was detained for 29 months in a PMLA case. The Court held that prolonged pre-trial detention triggers a liberal construction of bail provisions, and that Article 21 overrides statutory bail bars. Critically, the Court held that Section 479 BNSS applies to PMLA cases, expanding the scope of the first-time offender bail provision to special legislation. The Enforcement Directorate argued that an additional EOW FIR pending against the petitioner triggered Section 479(2) BNSS (multiple-case restriction), but the Court granted bail citing the petitioner's fundamental right to speedy trial.
Significance: Establishes that Section 479 BNSS's first-time offender provisions can operate even in cases governed by special legislation with stringent bail bars like the PMLA.
Veritect reference: DLHC010527012024_1_2024-11-20
Mohit v. State Govt NCT of Delhi (4 July 2025)
Court: Delhi High Court | Judge: Amit Sharma | Result: Bail denied
The petitioner had been in custody since 09-09-2021 (over three years and ten months) for abetment of suicide under Section 306 IPC, and had served more than one-third of the maximum sentence. However, the Court denied bail, holding that despite meeting the detention threshold under the first proviso to Section 479(1), the second proviso permits courts to deny bail where the circumstances of the case justify continued detention. The Court noted authenticated digital evidence (forensic reports confirming morphed images, fake Instagram account traced to petitioner's phone) and suicide notes implicating the petitioner in sustained harassment.
Significance: Demonstrates that Section 479 BNSS is not an automatic release mechanism. Courts retain discretion under the second proviso to deny bail even when the detention threshold is met, particularly where strong prima facie evidence exists.

Emerging patterns
Based on available post-July 2024 court orders from the Veritect database:
- Section 479 is being actively invoked: Multiple bail applications now cite Section 479 BNSS as a primary ground, particularly for undertrials who were arrested under the old CrPC but whose detention now falls under BNSS computation.
- Jail superintendent notifications are functioning: In the Suleman Samad case, the jail authorities proactively notified the trial court of the detention threshold being met, demonstrating that the Section 479(3) mechanism is operational in practice.
- Cross-applicability to special laws: The Tarun Kumar decision suggests Section 479 BNSS may apply even to detentions under PMLA, NDPS, and other special legislation, significantly expanding its reach beyond general criminal law.
- Second proviso as a safeguard: The Mohit decision confirms that the second proviso to Section 479(1) prevents automatic release and preserves judicial discretion in cases involving grave offences with strong prosecution evidence.
Frequently Asked Questions
Has the fundamental structure of bail law changed under BNSS?
No. The three-tier bail structure — bailable offence bail as a right, non-bailable offence bail at court discretion, and anticipatory bail before arrest — remains unchanged. The changes are primarily in the detail: enhanced provisions for undertrial release, removal of restrictive provisos in anticipatory bail, and introduction of statutory definitions.
What is the most significant bail reform in BNSS?
Section 479, which mandates release of first-time offenders who have served one-third of the maximum sentence and imposes a proactive duty on jail superintendents to apply for such release. This directly addresses the crisis of undertrial overcrowding in Indian prisons.
Does the right to default bail survive under BNSS?
Yes. The indefeasible right to default bail, recognized by the Supreme Court as a fundamental right of the accused, continues under Section 187(2) BNSS with the same 90-day and 60-day timelines.
Can anticipatory bail be granted for offences punishable with death?
The position remains the same as under CrPC — Section 482 BNSS does not expressly bar anticipatory bail for death-penalty offences, but courts have historically been reluctant to grant it. The expanded prohibition now also covers gang rape of women under 18.
What happens to bail orders passed under CrPC before 1 July 2024?
Bail orders passed under CrPC continue to remain valid. The transitional provisions ensure that proceedings under the old law are not invalidated. However, any fresh bail application filed after 1 July 2024 must be made under the corresponding BNSS provisions.
