The Ghost of Arnesh Kumar: Supreme Court Reins in Police Powers Under the New BNSS Regime

The Procedural Whiplash of the BNSS Era

The transition from the Code of Criminal Procedure, 1973 (CrPC) to the Bharatiya Nagarik Suraksha Sanhita (BNSS) has left trial courts and practicing advocates in a state of procedural whiplash. However, a flurry of recent Supreme Court and High Court rulings has made one thing abundantly clear: the apex court is not going to let the new criminal statutes become a blank cheque for executive overreach. In a series of defining judgments, the judiciary is actively transplanting the civil liberty safeguards of the CrPC era into the new BNSS framework, while simultaneously enforcing the new statutory checks placed on police powers.

For defense counsel, the message is clear: the statute numbers have changed, but the fundamental jurisprudence protecting the accused has not. More importantly, where the BNSS introduces new procedural hurdles for the prosecution, the Supreme Court is strictly enforcing them.

Notice Over Arrest: The Section 35 Mandate

Perhaps the most significant development for day-to-day criminal practice is the Supreme Court’s recent clarification on arrests for offences punishable by up to seven years of imprisonment. Under the old regime, Section 41 and 41A of the CrPC, read with the landmark Arnesh Kumar v. State of Bihar guidelines, dictated that police could not routinely arrest the accused for such offences without serving a notice of appearance.

With the enactment of the BNSS, there was immediate apprehension at the trial bar regarding how investigating agencies would exploit the transitional ambiguity. The Supreme Court has swiftly shut the door on any such adventurism.

The Supreme Court has unequivocally held that for offences punishable with imprisonment up to seven years, issuing a notice under Section 35(3) BNSS (the successor to Section 41A CrPC) is the absolute default rule. Arrest under Section 35(6) read with Section 35(1)(b) remains the strict exception.

Why this matters for your practice: If you are drafting an anticipatory bail application or challenging an illegal remand, your primary weapon remains unchanged, but your statutory citation must pivot. Magistrates are strictly bound to scrutinize the Investigating Officer's (IO) justification for bypassing the Section 35(3) notice. If the police fail to record special reasons for arrest under Section 35(6), the remand must be rejected. The ghost of Arnesh Kumar is very much alive in the BNSS.

The End of Unending Police Probes

For decades, Section 173(8) of the CrPC was the prosecution's favorite sword of Damocles. Investigating agencies routinely filed "final" charge sheets to defeat default bail under Section 167(2) CrPC, only to keep "further investigation" pending indefinitely, often without the explicit permission of the Magistrate.

The Supreme Court has now laid down the law on the BNSS equivalent. The Court ruled that under the new regime, the police cannot continue further investigation on their own volition after the initial report is filed. They must obtain explicit leave of court under the relevant BNSS provisions.

Practice Note: This is a massive tactical advantage for defense lawyers. The moment a charge sheet is filed, you must immediately object to any parallel, unilateral evidence-gathering by the IO. If the police file a supplementary charge sheet without prior magisterial leave, defense counsel should immediately move for its rejection at the threshold. This ruling effectively institutionalizes judicial supervision over the lifespan of an investigation.

Old Wine, New Bottles: Discharge and Framing of Charges

Are we looking at a clean slate for pre-trial procedures? Absolutely not. According to a recent SCC Online report, the Supreme Court has explicitly stated that the substantive legal standards governing discharge and framing of charges at the pre-trial stage remain unchanged under the BNSS.

The threshold tests laid down in precedents like Union of India v. Prafulla Kumar Samal and Sajjan Kumar v. CBI—whether there is a "grave suspicion" against the accused, and the prohibition on conducting a mini-trial at the charge-framing stage—continue to apply. The courts are treating the BNSS as a procedural continuation rather than a hard reset.

A New Shield: Pre-Cognizance Hearings

While the courts are importing old safeguards into the BNSS, they are also weaponizing new ones. In Parvinder Singh v. Directorate of Enforcement, the Supreme Court addressed the controversial intersection of the Prevention of Money Laundering Act (PMLA) and the BNSS. The Court ruled that a pre-cognizance hearing of the accused is mandatory when a complaint is filed and cognizance is taken after the BNSS has come into force.

This is a paradigm shift. Traditionally, the accused had no locus standi at the pre-cognizance stage. By strictly interpreting the new statutory framework, the Supreme Court has handed white-collar defense lawyers a golden opportunity to scuttle frivolous ED complaints before the Magistrate even issues process.

The Bottom Line

The lower courts are currently drowning in high-volume interpretive disputes over the BNS and BNSS, from the Delhi High Court referring conflicts over Section 223 BNSS to larger benches, to the Kerala High Court confirming that Section 447 BNSS allows direct approaches for transferring cases between Special Courts.

However, the overarching trend is clear: the Supreme Court is aggressively defending the procedural rights of the accused. For the sharp criminal litigator, the strategy is twofold: wield the new statutory mandates (like mandatory leave for further investigation and pre-cognizance hearings) to stall the prosecution, while relying confidently on entrenched CrPC precedents to protect your clients' personal liberty. The statute book may have been rewritten, but the Constitution has not.
