Section 35 BNSS: Arrest, Notice of Appearance and Recorded Reasons

The difference between suspicion and necessity

An allegation may justify investigation without automatically justifying arrest. Police powers exist to secure the investigation and prevent specific risks, not to punish a person before guilt is determined. That distinction underlies the Supreme Court's decision inArnesh Kumar v. State of Biharand remains central under the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), which came into force on 1 July 2024.

Section 35 BNSSsets out the circumstances in which a police officer may arrest without a warrant. In the categories governed by the statutory necessity test, the officer must look beyond the existence of a cognisable offence to factors such as preventing further offending, securing proper investigation, preventing evidence destruction, stopping witness intimidation and ensuring appearance before court. The relevant statutory category and punishment range matter; the provision should not be paraphrased as a uniform rule for every offence.

Reasons are a safeguard, not a formality

Recording a reason forces a decision-maker to connect general statutory language to case-specific facts. A formula such as'arrest necessary for investigation'should not be mistaken for an explanation ofwhycustody was necessary. Officers should be able to identify the particular risk and the evidence supporting it. Where appearance can be secured without arrest, the BNSS also provides a notice-of-appearance route under Section 35, subject to its conditions.

The Supreme Court inArnesh Kumarcriticised routine arrest in offences historically covered by the then Code of Criminal Procedure. Its reasoning helps explain why formal police discretion must be exercised on objective grounds. The shift to the BNSS requires practitioners to cite the current statutory provision while being attentive to the factual and legal scope of older precedent.

Which Section 35 rule applies?

For the category in Section 35(1)(b), the officer needs a reason to believe that the person committed the relevant cognisable offence and satisfaction that arrest is necessary for one of the listed purposes. These are cumulative requirements. An FIR supplies allegations to investigate; it does not dispense with the second inquiry.

The punishment range matters. Section 35 contains other arrest categories with their own conditions. The up-to-seven-years necessity framework should not be copied into a summary purporting to state every power of arrest. Equally, the presence of another category does not remove constitutional protection against arbitrary custody.

Section 35(7) adds a specific safeguard where an offence is punishable with imprisonment below three years and the person is infirm or above sixty: prior permission from an officer not below Deputy Superintendent of Police is required. The offence threshold and the personal condition operate together. Describing age alone as a universal requirement would misstate the clause.

What the Supreme Court clarified in January 2026

In Satender Kumar Antil v. CBI, 2026 INSC 115, the Court directly addressed Section 35 and offences punishable up to seven years. It treated notice as the rule and arrest as an exception requiring justification. The decision is a current BNSS authority in addition to the older CrPC cases.

A notice recipient must cooperate with its lawful terms. Continued compliance attracts Section 35(5) protection against arrest unless the officer records reasons why arrest is nevertheless required. Failure to appear does not remove the need to apply the statute carefully or comply with any competent court's order.

For a magistrate, the practical question is what material supports the stated risk. Has a witness reported a threat? Has the person tried to destroy a record? Is there evidence of evasion? Specific facts permit judicial scrutiny. Merely repeating the listed purposes of arrest does not show why those purposes require custody in this investigation.

Arrest legality and bail are connected but distinct

A challenge to the arrest examines the authority and procedure used to take a person into custody. A bail application asks whether continued detention is justified under the governing provision. The same facts may matter to both, but the remedies and thresholds can differ. The lawyer should identify the relief sought and use the constitutional protection of personal liberty alongside the current procedural text.

What counsel should examine

A defence lawyer should identify the FIR sections, their maximum punishments, the arrest chronology and whether the notice process applied. The arrest memo, grounds communicated, station-diary materials, reasons for arrest and production before the magistrate may become important. A bare allegation of technical non-compliance will not necessarily resolve a bail request; counsel must show how the legal requirement was engaged and breached.

For the prosecution, the most convincing position is equally factual. If there was a credible risk of absconding, interference with evidence or intimidation, it should be stated precisely and supported by material. Custodial interrogation should not become a substitute for explaining necessity. The magistrate's oversight is not a rubber stamp; judicial scrutiny is part of the safeguard.

Cooperation and judicial oversight

A fair procedure can protect an accused person while enabling law enforcement to pursue serious crime. Appropriate notices, documented cooperation and proportionate custodial powers are mutually reinforcing. They also reduce the possibility that a prosecution becomes focused on the legality of police conduct rather than the underlying allegations.

The record must justify custody when it is ordered. Later descriptions of a case as serious cannot replace the particular reasons the arresting officer and remand court were required to consider.
