Statutory Analysis of Default Bail: Section 187 & Section 479 BNSS vs CrPC Provisions
Under Indian criminal procedure, statutory detention limits ensure that state investigatory agencies cannot detain an accused indefinitely without filing a formal chargesheet. With the enactment of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), key provisions governing default bail and undertrial detention have been revised, introducing notable structural shifts from the former Code of Criminal Procedure, 1973 (CrPC).
Section 187 BNSS vs. Section 167(2) CrPC: Default Bail Framework
The statutory right to default bail (historically rooted in Section 167(2) of the CrPC) is codified in Section 187 of the BNSS. Under Section 187(3) BNSS, the magistrate is authorized to detain an accused in custody for a maximum period of:
- 90 days: Where the investigation relates to an offence punishable with death, imprisonment for life, or imprisonment for a term of not less than ten years.
- 60 days: Where the investigation relates to any other offence.
Upon the expiry of the applicable 60 or 90-day period, if the investigation is incomplete and no final chargesheet has been filed, an indefeasible right to be released on bail accrues in favour of the accused. The court cannot adjudicate the merits or gravity of the offence; release becomes a mandatory statutory command under Article 21 of the Constitution.
Section 479 BNSS vs. Section 436A CrPC: Maximum Detention of Undertrials
While Section 187 BNSS addresses the pre-chargesheet investigation phase, Section 479 BNSS (replacing Section 436A CrPC) governs the maximum period for which an undertrial prisoner can be detained during ongoing investigation, inquiry, or trial.
A major legislative reform introduced under Section 479(1) BNSS specifically safeguards first-time offenders. Where an individual has never previously been convicted of any offence in India, the court is mandated to release them on bail or on a personal bond (with or without sureties) if they have undergone detention for one-third of the maximum period of imprisonment specified for that offence. For recidivist or non-first-time offenders, the traditional threshold of one-half of the maximum punishment applies.
Crucially, Section 479 excludes offences for which the punishment of death or life imprisonment is specified by law.
Procedural Mandate to Assert Statutory Liberty
Although default bail under Section 187 BNSS is an absolute right, settled jurisprudence dictates that the accused must actively avail of this right before the investigating agency files the chargesheet. If the statutory deadline expires and the accused furnishes an application expressing readiness to post bail, that right cannot be defeated by a subsequent chargesheet filing.
