Release of Undertrial Prisoners Under Section 479 BNSS

Who can be released under section 479 BNSS?

Section 479 covers any person detained during the investigation, inquiry or trial of an offence under any law, provided the offence is not one for which death or life imprisonment is a possible punishment. It applies to undertrials only. Someone who has been convicted and is waiting for an appeal is not an undertrial; their route is suspension of sentence by the appellate court, which our post on criminal appeal or revision explains.

Two classes of undertrial benefit. Everyone who has spent up to one-half of the maximum term of imprisonment for the offence in custody is to be released by the court on bail. A first-time offender, meaning someone never convicted of any offence in the past, is to be released on a bond once they have spent up to one-third of the maximum term. A bond here means a personal bond, usually without sureties, though the court can ask for sureties if it records reasons.

Two outer limits apply to everyone. No undertrial can be detained beyond the maximum term of imprisonment provided for the offence, whatever else is going on. And the period of detention is counted only for custody in that case, not custody in another case or time spent on bail.

Which offences are excluded from section 479?

The exclusion turns on the punishment written in the section, not on what the prosecution expects. If death or imprisonment for life is one of the punishments for the offence, section 479 does not apply. Murder (section 103 BNS), rape (section 64), dowry death (section 80) and attempt to murder (section 109) are obvious examples.

Some exclusions surprise people. Forgery of a valuable security, will or similar document under section 338 BNS carries imprisonment for life as a possible sentence, so a person held mainly for that offence cannot use section 479, even though the case looks like a paper fraud. Criminal breach of trust by a public servant, banker or agent under section 316(5) is in the same position. Read the punishment clause of every section in the chargesheet before assuming eligibility.

Where section 479 is excluded, long custody can still support bail. The Supreme Court in Union of India v K.A. Najeeb (2021) held that prolonged incarceration with no early end to the trial can justify bail under Article 21, even under statutes with strict bail conditions. That is an argument for regular bail before the Sessions Court or High Court, not a mechanical release under section 479.

How do you calculate one-half and one-third of the maximum sentence?

Take the maximum term of imprisonment for the offence as written in the statute, then divide. The table shows common offences. Courts generally look at the most serious offence the person is held for. These are illustrations; check the exact sub-section in your chargesheet.

The count starts from the day of arrest in that case and includes police custody and judicial custody. It stops while the person is on bail. If the person was arrested, released, and arrested again in the same case, add the separate spells together.

What counts as delay caused by the accused?

The explanation to section 479(1) excludes from the count any period of detention caused by delay in proceedings on the part of the accused. This is where most section 479 applications are actually fought. The prosecution will go through the order sheets and point to every adjournment taken by the defence, every date the accused was not produced because of their own conduct, and every application that held up the trial.

Not every adjournment is the accused's fault. Dates lost because the prosecution witness did not appear, the IO was on leave, the court was on leave or the jail did not produce the accused are not delay by the accused. Nor is time taken in deciding an application the accused was entitled to file, such as a discharge application, unless it was plainly frivolous. A co-accused's adjournments should not be counted against you either, though prosecutors sometimes try.

When Advocate B.K. Singh prepares a section 479 application, the working document is a date-by-date table drawn from the certified order sheets: date, what happened, who asked for the next date and why. Courts respond to that table far better than to a general statement that the accused has been in jail a long time, and it leaves the prosecution little room to inflate the excluded period.

Who is a first-time offender under section 479?

The proviso describes a first-time offender as a person who has never been convicted of any offence in the past. The test is conviction, not arrest or FIR. A person who has been arrested before, or who was acquitted in an earlier case, remains a first-time offender. A person with an old conviction for any offence, even a minor one that ended in a fine, does not.

Be careful with two situations. A conviction that was set aside on appeal is no longer a conviction, so it should not count. A person released on probation after a finding of guilt is in a less settled position, because some laws remove the disqualification attached to a conviction while others do not; raise it openly rather than leaving the prosecution to find it.

Proof is usually simple. The accused files an affidavit that there is no previous conviction, and the court may call for a report from the police. Many Delhi courts rely on the jail's nominal roll, which records previous convictions and other cases. If the nominal roll is wrong, correct it before the hearing, because the court will treat it as the official record.

Does section 479 apply if more than one case is pending?

Section 479(2) says that where an investigation, inquiry or trial in more than one offence or in multiple cases is pending against a person, they shall not be released on bail by the court under this section. Read literally, it excludes anyone facing more than one case, and possibly anyone facing more than one offence in one FIR, which would be almost every accused.

That literal reading is being contested, and the point has not been finally settled. The better argument is that the bar targets separate pending proceedings, not several sections invoked in one FIR, because otherwise the first proviso would rarely apply. Until the Supreme Court decides it, expect the prosecution in Delhi courts to raise section 479(2) wherever there is a second FIR, and expect courts to read the record carefully.

Section 479(2) does not stop a court from granting regular bail under sections 480 or 483 on the merits. Long custody remains a strong ground in a regular bail application even where the statutory release is barred, and a person facing several minor cases may be able to apply for bail in each, case by case.

Can the court refuse release even after the period is complete?

Yes, in a limited way. Under the proviso to section 479(1), the court may, after hearing the Public Prosecutor and recording reasons in writing, order continued detention beyond one-half of the maximum term, or release the person on bail with sureties instead of a personal bond. This is an exception that needs reasons specific to the accused, such as a record of jumping bail or a real risk of absconding, not a general reference to the seriousness of the offence.

There is one limit no reason can override. The final proviso says no person shall be detained during investigation, inquiry or trial for more than the maximum term of imprisonment for the offence. If that point is reached, release is compulsory.

In practice, courts in Delhi usually grant release when the computation is clean, the accused is a first-time offender and there is a stable address. Refusals tend to follow disputes over the excluded period, a second pending case, or an accused who has absconded before in the same matter.

What is the jail superintendent's duty under section 479(3)?

Section 479(3) requires the superintendent of the jail to apply in writing to the court, without delay, when an undertrial completes one-half or one-third of the period, so that the court can proceed with release. This was added because many eligible undertrials never had anyone to file for them under the old section 436A.

In Delhi, undertrials are held mainly in the Tihar, Rohini and Mandoli jail complexes. Each jail maintains nominal rolls and custody records, and the Supreme Court has asked jail authorities across the country to identify eligible prisoners and move the courts. Undertrial Review Committees, chaired by the District Judge, also review the cases of undertrials who may be eligible.

Families should not wait for the jail to act. The superintendent's application is a safety net, not a substitute for a properly argued application from the accused's advocate. Jail applications are often generic and do not deal with the excluded period, which is exactly what the prosecution will contest.

How to apply for release under section 479 BNSS in a Delhi court

The application goes to the court where the case is pending: the magistrate during investigation or a magistrate's trial, and the Sessions Court where the case has been committed or is triable by it.

1. Get the custody certificate

   Ask the jail for a custody certificate or nominal roll showing the date of admission, all periods of custody in the case and any other pending cases or previous convictions. Families can request it through the advocate or the jail legal aid clinic.

2. List the sections and their maximum terms

   Take every section in the FIR and chargesheet, note its maximum punishment and check that none carries death or life imprisonment. Identify the most serious offence, since that sets the period.

3. Prepare the date-by-date table

   Obtain certified copies of the order sheets and record who caused each adjournment. Calculate the custody period with and without the dates the prosecution may call delay by the accused.

4. Draft and file the application

   Cite section 479, set out the computation, attach the custody certificate, order sheets and an affidavit on previous convictions, and state whether the accused is a first-time offender. Mention any other cases honestly.

5. Serve the Public Prosecutor

   The court will hear the prosecutor, who may file a reply contesting the period, the first-offender status or the other-cases point. Be ready with the order sheets on the date of hearing.

6. Furnish the bond

   If release is ordered on a personal bond, it is executed in court and a release warrant is sent to the jail. If sureties are required, keep surety documents and verification ready to avoid an extra night in custody.

Does section 479 apply to old cases registered before 1 July 2024?

Yes. Before 1 July 2024, section 436A CrPC gave release after one-half of the maximum term, with no special rule for first-time offenders. When the BNSS came in, the question was whether undertrials in older cases, still governed by the CrPC under section 531 BNSS, could claim the one-third benefit. On 23 August 2024 the Supreme Court recorded the Union Government's statement that section 479 applies to all undertrials, including those in cases registered before 1 July 2024, and proceeded on that basis.

In practical terms, an undertrial in an old IPC case who is a first-time offender can apply for release after one-third of the maximum term under the IPC section charged. The calculation uses the punishment in the IPC section, not the BNS equivalent, because the offence is still an IPC offence. Our post on which law applies to an old FIR explains that split between substantive and procedural law.

The application can cite both section 479 BNSS and the Supreme Court's order. Where the court is reluctant, the alternative is to argue the same facts as a ground for regular bail.

Does section 479 apply in NDPS, PMLA and other special law cases?

Generally yes, unless the special law excludes it. Courts applied section 436A to cases under special statutes, and the Supreme Court noted in Vijay Madanlal Choudhary v Union of India (2022) that section 436A was available to persons accused under the PMLA. The same reasoning is generally carried over to section 479, since special laws apply the general procedure code except where they provide otherwise.

The arithmetic can still be daunting. A commercial quantity NDPS case with a maximum of twenty years means ten years for the general rule. That is why long-custody arguments in NDPS cases are usually made under Article 21 alongside the section 37 test, as discussed in our post on commercial quantity bail and on our NDPS and NCB case page.

For PMLA, the maximum term for money laundering is seven years, or ten years where the scheduled offence is under the NDPS Act. Half of seven is three and a half years. Long custody in PMLA cases has been argued successfully as a ground for bail even with the twin conditions under section 45, and our PMLA practice page covers that bail standard.

How is section 479 different from default bail and regular bail?

Default bail under section 187 depends on one thing: whether the chargesheet was filed within 60 or 90 days of remand. It is about investigation delay, it is available early in the case, and it is lost once the chargesheet comes in. Section 479 depends on time served against the maximum sentence, and it is available at any stage until the trial ends.

Regular bail under sections 480 and 483 is a discretion exercised on the merits: the gravity of the accusation, the evidence, the risk of absconding or tampering, and the time in custody. Section 479 is closer to a statutory entitlement once the conditions are met, with only a narrow discretion to refuse. An undertrial does not have to wait for section 479 to apply for regular bail, and should not.

Think of section 479 as the floor. If regular bail is refused and default bail is not available, section 479 sets the date by which the law expects release, and that date should be in the family's diary from the first week of custody.

Documents for a section 479 application

What conditions apply after release under section 479?

Release under section 479 is on bail or bond, so the ordinary conditions follow. The court will require attendance on every date, a residence address, and usually an undertaking not to contact witnesses or the complainant. It may require the accused to stay within Delhi NCR or surrender a passport where travel abroad is a concern.

Breaking the conditions can lead to cancellation and re-arrest, just as with any other bail. The grounds and procedure are explained in our post on when bail can be cancelled. If a condition becomes impossible to follow, for example because of a job in another city, apply to the court to change it rather than ignoring it.

Release also does not end the case. The trial continues, and the time spent in custody is set off against any sentence if the person is later convicted, under section 468 BNSS. For a first-time offender in a case carrying seven years, the custody already served may by then be a large part of the likely sentence.

Common mistakes in section 479 applications

The most common mistake is counting from the wrong date or the wrong offence. Families count from the FIR rather than the arrest, or use a lesser offence when the chargesheet also invokes a heavier one. The second is ignoring the excluded period and filing an application that collapses as soon as the prosecutor reads out the order sheets.

Others include not mentioning a second pending case, which then surfaces in the nominal roll and damages credibility, and claiming first-offender status without checking for an old fine in a minor case. Some people also wait for the jail to apply, losing months. And some file a section 479 application when default bail was still available, which is quicker and cleaner.

Finally, people often give up when section 479 is refused because of a second case or an excluded offence. Long custody remains a ground for regular bail, and in the right case for an Article 21 argument before the High Court. Advocate B.K. Singh's practice in such matters is to keep the custody table updated every month, so that a fresh bail application can be filed the moment the facts shift.
