Most bail arguments are about the offence: its gravity, the accused's role, the strength of the material. A distinct and increasingly important line of cases is about time — the years an undertrial has already spent in custody against the realistic horizon of the trial. The constitutional anchor is Article 21, and the leading modern statement is Union of India v. K.A. Najeeb (2021), where the Supreme Court held that even the rigours of a special statute's bail-limiting provision do not oust the constitutional courts' power to grant bail when incarceration has become punitive by delay. With Section 479 of the BNSS now codifying release for undertrials who have served substantial portions of the maximum sentence, delay-based bail rests on two mutually reinforcing foundations.
Why time changes the bail question
Pre-trial detention is preventive, not punitive: it exists to secure attendance, protect the investigation and prevent tampering. Each of those purposes weakens as the case ages. After the charge sheet, the investigation is complete; after the evidence of key witnesses, tampering risk shrinks; and as custody approaches the sentence the offence would realistically attract, detention starts doing the work of punishment without a conviction. That is the point at which Article 21 — the right to life and personal liberty, which includes the right to a speedy trial — converts delay from a sympathy factor into a legal ground.
The Najeeb framework
In Union of India v. K.A. Najeeb, the respondent had spent years in custody while his co-accused had been tried and sentenced, and the trial against him was yet to meaningfully progress. The Supreme Court upheld the High Court's grant of bail despite Section 43D(5) UAPA, reasoning that the statutory embargo governs the merits-based bail inquiry, while constitutional courts retain the power to relieve the violation of fundamental rights caused by inordinate delay. The decision supplies three working propositions:
The statutory track: Section 479 BNSS
| Situation | Rule under Section 479 BNSS |
|---|---|
| Undertrial has undergone half the maximum imprisonment for the offence | Shall be released on bail (offences punishable with death or life imprisonment excepted) |
| First-time offender (never previously convicted) | Shall be released on bond after one-third of the maximum period |
| Multiple pending cases or proceedings | Release under the section is unavailable where proceedings in more than one offence or multiple cases are pending |
| Institutional duty | The jail superintendent must move the court when the threshold is crossed |
The provision, and the Supreme Court's directions for its retrospective application to undertrials across the country, make custody arithmetic a routine part of every bail file: counsel should compute the maximum sentence, the custody undergone, and the fraction crossed, at each listing.
Building a delay-based bail application
- State the custody timeline precisely: date of arrest, remand history, and total period undergone, supported by the custody certificate.
- Show the trial's realistic horizon: charges framed or not, witnesses cited versus examined, and the pace of past listings.
- Attribute the delay honestly: adjournments sought by the accused weaken the argument; systemic delay and prosecution absences strengthen it.
- Engage the merits briefly: delay arguments work best alongside, not instead of, a viable case on role and evidence.
- Propose conditions: a concrete, verifiable set of conditions answers the apprehensions that otherwise defeat the plea.
Practice note: Delay jurisprudence is a shield for liberty, not a licence for obstruction. Courts scrutinise whether the applicant himself protracted the trial, and bail granted on delay grounds is vulnerable to cancellation if the accused thereafter delays proceedings or approaches witnesses. The discipline that wins these applications is documentary: order-sheets, custody certificates and witness charts, not adjectives.
Frequently Asked Questions
Can bail be granted only because custody has been long?
Length of custody is never the whole analysis, but it can be the decisive factor. Where the accused has spent years as an undertrial, the trial is nowhere near conclusion for reasons not attributable to him, and further detention would be punishment before verdict, constitutional courts grant bail on Article 21 grounds — with conditions guarding against flight and tampering.
What did Union of India v. K.A. Najeeb decide?
A three-Judge Bench held on 1 February 2021 that statutory restrictions on bail — there, Section 43D(5) of the UAPA — do not exclude the constitutional courts' ability to enlarge an accused on bail where the right to a speedy trial under Article 21 has been infringed by long incarceration and no realistic prospect of early trial completion. Statutory rigour and constitutional relief operate in harmony, not competition.
How does Section 479 BNSS change the position?
Section 479 BNSS (successor to Section 436A CrPC) mandates consideration of release where an undertrial has undergone up to one-half of the maximum imprisonment for the offence — one-third for a first-time offender — except in offences punishable with death or life imprisonment. It gives the delay principle a statutory, largely rule-based form that operates even before the constitutional threshold is reached.
Does delay-based bail apply to serious economic offences?
Yes, the principle is offence-neutral, though courts weigh gravity in fixing conditions. Long pre-trial custody in complex trials with voluminous evidence and many witnesses — where conclusion is realistically years away — is a recognised basis for bail notwithstanding the seriousness of the allegations.
