Over 75% of India’s prison population consists of undertrial prisoners — people who have not been convicted of any offence but are waiting for their trial to conclude. Many of them have already spent more time in custody than the maximum sentence they would receive even if convicted. Section 479 of the Bharatiya Nagarik Suraksha Sanhita 2023 is Parliament’s direct response to this. It gives undertrial prisoners a statutory right to bail once they cross a defined threshold of detention — not as a matter of the court’s discretion, but as a legal entitlement.
This article covers the complete bail framework under BNSS 2023, with the CrPC equivalents for reference, the key changes that BNSS introduced, and the Supreme Court judgments of 2024 and 2025 that have shaped how Section 479 is applied in practice.
Types of Bail Under BNSS 2023
| Type of Bail | BNSS Section | Old CrPC Section | Who Grants | Key Feature |
| Bail in bailable offences | Section 478 | Section 436 | Police officer or Magistrate | Right to bail — not discretionary. The accused cannot be detained if they are willing to furnish bail. |
| Undertrial bail (half sentence rule) | Section 479 | Section 436A | Court | Statutory entitlement after serving half or one-third (first-time offenders) of maximum sentence. Main subject of this article. |
| Bail in non-bailable offences | Section 480 | Section 437 | Magistrate | Discretionary. Court considers nature of offence, evidence, and accused’s history. |
| Bail pending appeal | Section 481 | Section 389 | Appellate Court | Granted while appeal against conviction is pending. |
| Anticipatory bail (pre-arrest bail) | Section 482 | Section 438 | Sessions Court or High Court | Granted before arrest where person has reasonable apprehension of arrest. |
| Bail by Sessions Court or High Court | Section 483 | Section 439 | Sessions Court or HC | Concurrent jurisdiction with Magistrate for non-bailable offences — wider powers. |
Section 479 BNSS — Undertrial Bail in Detail
Section 479 BNSS replaced Section 436A CrPC. The structure is similar but with one important addition for first-time offenders.
| Section 479 BNSS — Exact Rule: Where a person has, during investigation, inquiry, or trial, undergone detention for a period extending up to ONE-HALF of the maximum period of imprisonment specified for that offence — the court SHALL release the person on bail. FIRST-TIME OFFENDER PROVISION (New in BNSS): Where such person is a first-time offender (never convicted of any offence in the past) — the court SHALL release on bond if the person has undergone detention for a period extending up to ONE-THIRD of the maximum period of imprisonment specified for that offence. “SHALL” = mandatory — court has no discretion once threshold is crossed. EXCEPTIONS — Section 479 does NOT apply where: → The offence is punishable with death or life imprisonment → The person has two or more cases pending in different FIRs → Court specifically records reasons to deny (extraordinary circumstances) |
Section 479 vs Section 436A CrPC — What Changed
| Aspect | Section 436A CrPC (Old) | Section 479 BNSS (New from 1 July 2024) |
| Half sentence rule | Same — half of maximum sentence | Same |
| First-time offender | No special provision — all undertrials same threshold | One-third threshold for first-time offenders — NEW |
| Multiple FIRs | Not expressly addressed | Expressly excluded — Section 479 not available if accused has cases in multiple FIRs |
| Retrospective application | Only for post-CrPC cases | SC held in August 2024 — applies to ALL undertrials including pre-July 2024 cases |
| Court’s discretion | Court “may” release | Court “shall” release — stronger language |
| Definition of bail | Not defined in CrPC | BNSS Section 2(b) defines bail for the first time |
Supreme Court Cases — Section 479 BNSS
1. Re: Inhuman Conditions in 1382 Prisons (2024 INSC 519 — August 23, 2024)
This is the landmark judgment on Section 479 BNSS. The Supreme Court bench of Justices Hima Kohli and Sandeep Mehta held that Section 479 BNSS applies retrospectively to all undertrial prisoners across India — including those whose cases were registered before 1 July 2024. The Court directed: all jail superintendents to proactively identify undertrial prisoners who have crossed the half-sentence or one-third threshold; all High Courts to monitor compliance; and courts at all levels to give Section 479 applications priority and decide within three months. The retrospective application was significant because it meant lakhs of pre-July 2024 undertrials immediately became eligible.
2. Section 479 BNSS and PMLA — 2025
The Supreme Court in 2025 addressed whether Section 479 BNSS applies to undertrial prisoners in PMLA (Prevention of Money Laundering Act) cases, which have stringent twin-condition bail restrictions under Section 45 PMLA. The Court held that Section 479 BNSS applies even to PMLA cases — a first-time offender who has served one-third of the maximum sentence can seek bail under Section 479 BNSS even though PMLA Section 45 makes bail otherwise very difficult to obtain. This judgment significantly eased bail prospects for long-detained PMLA undertrials and is directly testable as a current affairs Mains question on bail law.
3. Satender Kumar Antil v. CBI (2021) — Still Binding for BNSS Bail Applications
Though decided under CrPC, Satender Kumar Antil v. CBI (2021) 10 SCC 51 issued detailed guidelines on bail that continue to bind all courts under BNSS as well. The Supreme Court held that courts and police must apply the principle that bail is the rule and jail is the exception, particularly for offences not involving violence. The Court criticised the practice of courts refusing bail without recording reasons, and directed that wherever an arrested person is not likely to receive a sentence of more than 7 years, bail should ordinarily be considered. These guidelines inform how Section 480 BNSS discretionary bail applications are decided.
Section 482 BNSS — Anticipatory Bail
Anticipatory bail under Section 482 BNSS (was Section 438 CrPC) allows a person who has a reasonable apprehension of arrest for a non-bailable offence to approach the Sessions Court or High Court for bail in anticipation. The provision is available even after an FIR is filed, as long as the person has not yet been arrested. The substantive grounds for granting anticipatory bail remain unchanged from CrPC: the nature and gravity of the accusation, the antecedents of the applicant, the possibility of the applicant fleeing justice, and whether the accusation appears to be made to humiliate or injure the applicant.
One post-BNSS development: the Allahabad High Court held in December 2025 that Section 482 BNSS applies retrospectively — meaning anticipatory bail applications can be filed under BNSS even for offences committed before 1 July 2024. Another development: Section 18 of the SC/ST (Prevention of Atrocities) Act bars anticipatory bail by reference to “Section 438 CrPC.” Whether this bar now applies to Section 482 BNSS is a live legal question that different High Courts have answered differently as of July 2026.
Bail Law — Mains Exam Format

| Step 3 — Apply discretionary bail factors | For Section 480 — nature of offence, evidence, accused’s history, flight risk, Satender Kumar Antil guidelines. |
| Step 4 — Check anticipatory bail | If accused not yet arrested — Section 482 BNSS — Sessions Court or HC — reasonable apprehension of arrest for non-bailable offence. |
| Step 5 — Cite SC cases | Re: Inhuman Conditions 1382 Prisons (2024 INSC 519) for Section 479, Satender Kumar Antil for general bail guidelines, PMLA 2025 case if PMLA involved. |

What is the difference between Section 479 and Section 482 BNSS?
Section 479 BNSS is the undertrial bail provision — it applies after a person has already been arrested and has spent half (or one-third for first-time offenders) of the maximum sentence in custody. Section 482 BNSS is anticipatory bail — it is sought before arrest, by a person who has a reasonable apprehension of being arrested for a non-bailable offence. Section 479 is a mandatory release once the threshold is met. Section 482 is discretionary — the Sessions Court or High Court decides based on the facts.
Does Section 479 BNSS apply to death penalty or life imprisonment cases?
No. Section 479 BNSS expressly excludes offences where the punishment of death or life imprisonment has been specified as one of the punishments. So a person charged with murder under Section 101/103 BNS, gang rape under Section 70 BNS, or any other offence that carries death or life as a possible sentence cannot use Section 479 BNSS to seek undertrial bail on the half-sentence ground. They must apply for bail under Section 480 BNSS (non-bailable offences) on general discretionary grounds.
