The 24-Hour Clock and Section 346: How High Courts Are Rewriting BNSS Remand Jurisprudence

The New Arithmetic of Custody

Two years into the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), the dust is finally settling on what was initially feared to be a procedural free-for-all. The most significant recent developments concern not the substantive offences under the Bharatiya Nyaya Sanhita (BNS), but the mechanics of personal liberty—specifically, how courts are interpreting the BNSS’s custody timelines in ways that subtly recalibrate the balance between investigative necessity and constitutional safeguards.

The Kerala High Court’s recent clarification that the 24-hour production clock under Section 57 BNSS runs from formal arrest, not from prior statutory detention, represents a fundamental shift in remand practice. By holding that pre-arrest detention under special statutes (such as ED or CBI custody) does not trigger the constitutional 24-hour mandate, the Court has effectively created a bifurcated custody regime. This matters immensely for practitioners representing clients in multi-agency investigations: the moment of “formal arrest” by the state police now becomes the critical constitutional trigger, not the earlier deprivation of liberty by central agencies.

The 15-Day Myth and Section 346(2)

Equally consequential is the Gujarat High Court’s robust interpretation of Section 346(2) BNSS, which permits magistrates to authorise detention beyond the traditional 15-day police custody limit in specific circumstances. The Court’s observation that remand beyond 15 days is not per se illegal—and that habeas corpus will not automatically lie—signals a judicial willingness to move beyond the mechanical application of CrPC-era timelines.

"The remedy for illegal arrest is release plus corrective procedure, not immunity from lawful custody." This encapsulates the emerging judicial philosophy: procedural irregularities are to be cured, not weaponised to create permanent bars against prosecution.

This interpretation aligns with the BNSS’s broader architecture, which distinguishes between police custody (Section 346(1)) and judicial custody, while allowing for mixed remands. For defence counsel, this means the old strategy of seeking immediate release upon crossing the 15-day threshold requires recalibration. The focus must now shift to the nature of the remand order and whether the magistrate applied judicial mind to the necessity of extended custody, rather than merely counting days.

Default Bail: The UAPA Exception Confirmed

The Delhi High Court’s ruling that UAPA accused remain entitled to default bail only after 180 days, not 90, even after BNSS’s commencement, resolves a critical transitional uncertainty. Section 479 BNSS (the default bail provision) must now be read alongside special statutes, and the Court has correctly held that the special law prevails.

This creates a two-track default bail system that practitioners must navigate carefully:

• Standard IPC/BNS offences: 60/90-day default bail under Section 479 BNSS
• Special statutes (UAPA, NDPS, etc.): Extended periods as per the special statute, unaffected by BNSS

The Jammu & Kashmir and Ladakh High Court’s additional gloss—that Section 479 does not mandate automatic release upon completion of the period, but requires harmonious construction with its provisos—adds another layer. Default bail is no longer a mechanical right but a discretionary remedy contingent upon the accused’s conduct and the investigation’s bona fides.

The Cognizance Transition Trap

Perhaps the most practically significant development for trial practitioners is the Supreme Court’s clarification on transitional cognizance. When a Magistrate applies judicial mind and finds a prima facie case after BNSS came into force (July 1, 2024), cognizance is deemed taken on that later date, triggering the proviso to Section 223 BNSS.

This means accused persons in pre-BNSS FIRs now enjoy the right to be heard before process is issued—a CrPC novelty that did not exist for pre-2024 cases. Defence counsel must immediately audit pending matters: if cognizance was taken post-BNSS, the failure to provide a pre-cognizance hearing renders the summoning order vulnerable. This is not mere procedural pedantry; it strikes at the root of the magistrate’s jurisdiction to proceed.

Strategic Implications for Practice

These developments collectively suggest that the BNSS is evolving into a more flexible, less arithmetic procedure code than the CrPC. The Kerala HC’s permission for same-day re-arrest following release due to illegal custody—provided statutory formalities are met—further indicates that courts are prioritising substantive justice over procedural technicalities.

For criminal practitioners, the message is clear: the BNSS demands a more sophisticated engagement with custody jurisprudence. The days of automatic applications upon crossing numerical thresholds are over. Success now depends on demonstrating how the custody violates the specific procedural safeguards of the BNSS, rather than simply pointing to the calendar.

As the Supreme Court continues to hear the constitutional challenge to Section 152 BNS (the sedition analogue), and as more High Courts weigh in on Section 69 BNS (false promise to marry), the procedural framework established by these custody and remand decisions will provide the stable foundation upon which substantive criminal law will develop. The BNSS is not merely the CrPC with new section numbers—it is a distinct procedural philosophy that privileges judicial discretion over rigid timelines, and practitioners ignore this shift at their clients’ peril.
