Notice over Arrest, and the PMLA Roadblock: How the Supreme Court is Weaponizing the BNSS for the Defense in 2026

When the Bharatiya Nagarik Suraksha Sanhita (BNSS) replaced the Code of Criminal Procedure (CrPC), the collective anxiety among the criminal bar was palpable. Critics warned of expanded police powers and extended remand periods. But as the Supreme Court’s 2026 docket unfolds, a radically different picture is emerging. In a flurry of recent judgments, the Apex Court is actively weaponizing the BNSS to rein in investigating agencies, laying down hard procedural boundaries that every defense counsel needs to leverage immediately.

The message from the top court is unequivocal: the BNSS is not a blank cheque for the State. From mandating notices over arrests to forcing pre-cognizance hearings in PMLA matters, here is how the latest jurisprudence fundamentally alters criminal defense practice.

Statutory Life Support for Arnesh Kumar: Section 35 BNSS

For years, litigators have wielded Arnesh Kumar v. State of Bihar to fight off arbitrary arrests under Section 41 of the CrPC. With the transition to the BNSS, the Supreme Court has now cemented those guidelines into a strict statutory mandate.

The Court recently clarified that for offences punishable with imprisonment up to seven years, issuing a notice of appearance under Section 35(3) BNSS is the absolute default rule. Arrest under Section 35(6) read with Section 35(1)(b) is strictly an exception, requiring highly specific, recorded justifications.

"The police cannot treat Section 35(6) as a mere procedural formality to bypass the rule of notice. The burden to justify an arrest for offences up to seven years is now heavier than ever."

Practice Point: Stop treating bail applications as your first line of defense. Your immediate strategy at the remand stage must be to challenge the legality of the arrest itself. If the investigating officer bypassed a Section 35(3) notice without concrete justification, you have grounds to challenge the remand directly. Interestingly, while the Gujarat High Court recently ruled that remand beyond 15 days isn't strictly illegal in certain custody situations, challenging the initial arrest under Section 35 non-compliance remains your strongest weapon.

Killing the Mechanical FIR: Section 173(3) BNSS

The mechanical registration of FIRs—especially in commercial disputes dressed as cheating or matrimonial discord—has long plagued the system. While Lalita Kumari allowed for preliminary enquiries, the Supreme Court has now breathed life into Section 173(3) BNSS, explicitly describing it as a statutory safeguard against the registration of FIRs on vague or doubtful allegations.

Under BNSS, the police are empowered (and now implicitly encouraged by the SC) to conduct a preliminary enquiry before registering an FIR.

Practice Point: When representing clients facing imminent, frivolous FIRs, pre-emptive representation to the SHO and the SP invoking Section 173(3) BNSS is essential. You now have Supreme Court backing to argue that an FIR should not mechanically follow a complaint without a preliminary filter.

The PMLA Bombshell: Mandatory Pre-Cognizance Hearings

Perhaps the most seismic shift in white-collar defense comes from the Supreme Court’s recent ruling on the Prevention of Money Laundering Act (PMLA). The Court held that a pre-cognizance hearing of the accused is mandatory when cognizance is taken after the commencement of the BNSS in a PMLA complaint.

This is a direct application of the spirit of Section 223 BNSS, which grants the accused an opportunity to be heard before a Magistrate takes cognizance of a complaint. The Directorate of Enforcement (ED) is notorious for filing voluminous prosecution complaints and securing mechanical cognizance. By enforcing a pre-cognizance hearing, the Supreme Court has handed defense lawyers a golden opportunity to nip baseless money laundering prosecutions in the bud.

Note: The scope of Section 223 BNSS is currently so hotly contested that the Delhi High Court has referred potential conflicts regarding its interpretation to a larger bench. Keep a close watch on this space—it is the defining procedural battleground of 2026.

Closing the "Further Investigation" Loophole

Under Section 173(8) of the old CrPC, police frequently kept the sword of "further investigation" hanging over the accused, filing endless supplementary charge-sheets to delay trials or harass newly added accused.

The Supreme Court has now clamped down on this practice under the new regime. The Court held that police cannot conduct further investigation on their own after filing a final report; they must obtain the express court’s leave under the BNSS framework. This severely curbs the investigating agency's ability to arbitrarily reopen closed loops just as a trial is set to commence.

The Takeaway for Litigators

The BNSS is proving to be a double-edged sword, but the Supreme Court is actively sharpening the edge that protects civil liberties. The days of relying purely on CrPC precedents are over. To succeed in 2026, defense lawyers must aggressively invoke Section 35(3) to block arrests, Section 173(3) to force preliminary enquiries, and demand pre-cognizance hearings under Section 223. The statutory tools are there—it is now on the Bar to use them.
