The Spirit of Arnesh Kumar Survives: Supreme Court Cements Arrest Safeguards and CrPC Continuity Under BNSS

The BNSS is Not a Blank Slate for Police Overreach

For the past several months, the Indian criminal bar has been wrestling with a pervasive anxiety: does the Bharatiya Nagarik Suraksha Sanhita (BNSS) wipe out decades of hard-fought procedural safeguards? The police machinery certainly seemed to hope so. But in a vital series of recent rulings, the Supreme Court has fired a warning shot across the bows of investigating agencies, making one thing abundantly clear—the section numbers may have changed, but the constitutional guardrails remain intact.

The most consequential development for daily practice comes from the Supreme Court's definitive clarification on the arrest matrix under the BNSS for offences punishable with imprisonment up to seven years. The Court has laid down an unequivocal mandate: Notice under Section 35(3) BNSS is the rule, and arrest under Section 35(6) read with Section 35(1)(b) is the exception.

Transplanting Section 41A CrPC into Section 35 BNSS

To understand why this matters, we must look at the transition from the Code of Criminal Procedure (CrPC) to the BNSS. Under the old regime, Section 41A CrPC, read with the landmark Arnesh Kumar v. State of Bihar guidelines, served as the primary shield against arbitrary arrests in offences carrying a sentence of up to seven years. Investigating Officers (IOs) were bound to issue a notice of appearance rather than effectuating a mechanical arrest.

Under the new code, Section 35(3) BNSS is the reincarnation of Section 41A CrPC. However, early reports from trial courts suggested a disturbing trend: police were exploiting the novelty of the BNSS to bypass these notice requirements, leaning heavily on the arrest powers under Section 35(6) and 35(1)(b).

The Supreme Court has now slammed the door on this practice. By ruling that Section 35(3) notice is the default statutory rule, the Court has effectively transplanted the Arnesh Kumar jurisprudence directly into the BNSS framework. For defense counsel, this is your primary weapon at the remand stage.

"If an Investigating Officer produces an accused before a Magistrate for offences punishable up to seven years without first exhausting the notice procedure under Section 35(3) BNSS, the arrest is fundamentally defective. Magistrates must not act as post offices for the police; they are duty-bound to reject remand and grant bail if the Section 35(1)(b) exceptions are not strictly met and documented."

Pre-Trial Jurisprudence: No Material Shift in Discharge Standards

The Supreme Court didn’t stop at arrests. In another major relief for trial lawyers, the Court recently held that CrPC discharge and framing-of-charge jurisprudence continues unchanged under the BNSS.

Under the old regime, Sections 227 and 228 of the CrPC governed discharge and the framing of charges. Decades of Supreme Court precedent—from Union of India v. Prafulla Kumar Samal to Sajjan Kumar v. CBI—established that a judge must sift and weigh the evidence for the limited purpose of finding out whether a prima facie case exists. The judge is not a mere mouthpiece of the prosecution.

With the BNSS coming into force, prosecutors have occasionally argued that the "new" procedural standards allow for a looser threshold at the charge-framing stage. The Supreme Court has categorically rejected this. The legal standards have not materially shifted. Strong exculpatory material can still defeat a prosecution at an early stage, and in a parallel ruling, the Court reiterated that criminal proceedings can and should be quashed when reliable material disproves the allegations.

The takeaway for defense lawyers is simple: Do not let trial courts discard your old case law compilations. The substantive standard for discharge remains identical.

Custody, Investigation, and the PMLA Intersection

High Courts and the Supreme Court are actively ironing out other transitional kinks in the BNSS, and practitioners must take note of these procedural nuances:

1. The 15-Day Custody Limit: Interpreting Section 187 BNSS (the equivalent of Section 167 CrPC), the Delhi High Court has clarified that the period an accused spends on interim bail is excluded from the time limit for calculating police custody. This prevents accused persons from running out the clock on police remand by securing short-term interim bail.

2. Supplementary Investigations: The Supreme Court has issued a sharp reminder that further investigation after filing a final report requires the express leave of the court. The police cannot unilaterally embark on a supplementary probe once the final report is on record under the BNSS, curbing the notorious practice of keeping investigations "pending" indefinitely to harass the accused.

3. White-Collar Defense: In a massively important ruling for economic offenses, the Supreme Court held that a pre-cognizance hearing of the accused is mandatory in a PMLA complaint where cognizance is taken after the BNSS commenced. This inserts a critical layer of judicial scrutiny before the draconian machinery of the PMLA fully activates against a client.

The Verdict for Practitioners

The overarching narrative from the Supreme Court in 2026 is one of judicial continuity. The executive may have overhauled the statute books, but the judiciary is refusing to let constitutional liberties get lost in translation.

As lawyers, our strategy must adapt immediately. We must aggressively cite these recent Supreme Court rulings to remind Magistrates and Sessions Judges that the BNSS is not a license for procedural regression. When a client faces an offense punishable by up to seven years, your first demand must be compliance with Section 35(3) BNSS. When arguing for discharge, confidently rely on your time-tested CrPC judgments. The old laws are dead, but their jurisprudence is very much alive.
