The effective challenge is built file-by-file: offence, punishment, reason to believe, statutory necessity, notice, written reasons, safeguards and remand. 2026 position For offences punishable up to 7 years, notice is the rule. Arrest is the exception. In January 2026, the Supreme Court clarified that Section 35 must be applied as a liberty-protecting framework: arrest is discretionary, necessity must be objectively justified, and the statutory safeguards must be followed in letter and spirit. §35 BNSS Notice First Recorded Reasons Remand Scrutiny Inside this guide 1.

Challenge bundle An illegal-arrest challenge should not begin with outrage. It should begin with a legal audit. What offence is alleged? What is the prescribed punishment? Which clause of Section 35 authorises arrest? What material created the “reason to believe”? Which statutory necessity ground existed? Why was notice insufficient? What reasons were written down? And what did the Magistrate actually scrutinise at remand? 1. Treat Section 35 as a decision tree, not a general arrest power Section 35 of the Bharatiya Nagarik Suraksha Sanhita, 2023 governs when police may arrest without warrant. The provision is not a single blanket permission. Different clauses operate depending on the nature of the offence, the punishment prescribed, the information available to the officer and the necessity for custody. For the highly litigated category of a cognizable offence punishable with imprisonment that may extend to seven years, the core Section 35(1)(b) analysis has two separate limbs. First, there must be a lawful reason to believe , based on the complaint, credible information or reasonable suspicion, that the person committed the offence. Second, arrest must actually be necessary for at least one of the statutory purposes. The two-stage arrest test Cognizable offence Punishment up to 7 years Reason to believe One statutory necessity ground Supreme Court · 15 January 2026 In Satender Kumar Antil v. CBI & Anr., 2026 INSC 115 , the Supreme Court held that Sections 35(1)(b)(i) and 35(1)(b)(ii) must be read together. A reason to believe that the person committed the offence is not enough; at least one statutory necessity condition must also exist. This is the first practical mistake to avoid: never let the arrest argument collapse into “the FIR is serious.” Seriousness may be relevant, but Section 35 asks a more precise question— why was custodial arrest necessary for this person, in this investigation, at this time? 2. Start with the exact offence and punishment Before attacking the arrest, identify each invoked BNS or special-law provision and its punishment. Do not assume that an IPC-era understanding maps automatically onto the BNS. The punishment bracket determines which statutory arrest route applies. Build an arrest-threshold sheet Provision Cognizable? Maximum punishment Section 35 route Arrest issue Offence A Yes 5 years §35(1)(b) Reason to believe + necessity Offence B No 2 years Check warrant / other power Arrest without warrant requires separate authority Special-law offence Verify Verify Read special statute + BNSS Special procedure may modify general rule Practice rule: the first annexure in your arrest challenge should often be a one-page chart of the offences invoked, punishment prescribed, cognizable status and the exact statutory arrest clause relied upon. 3. Test the necessity grounds one by one For the Section 35(1)(b) up-to-seven-year framework, arrest must be necessary for one or more of the statutory purposes. Broadly, the provision asks whether custody is needed to prevent a further offence, permit proper investigation, prevent disappearance or tampering of evidence, stop inducement/threat/promise to persons acquainted with the facts, or ensure the accused's presence in court. Necessity matrix Statutory purpose Question for the file Evidence supporting it Prevent further offence What concrete risk of repetition existed? Prior conduct? Threat? Ongoing access? Proper investigation Why could investigation not proceed without custody? Specific recovery? Confrontation? Concealed evidence? Protect evidence What evidence could be destroyed or altered? Identified device, record, location or material? Protect witnesses Was any threat, inducement or pressure actually shown? Complaint, message, call, conduct? Secure court presence Was the accused absconding or avoiding process? Unserved notices, changed address, evasion? A copied paragraph reproducing every statutory ground is not the same as a factual justification. The Supreme Court has repeatedly disapproved mechanical reproduction of statutory language. Ask the investigating officer's record to identify the facts connecting this accused to the chosen necessity ground. “Why arrest?” is not rhetoric. It is the statutory question.

Demand the reasons actually recorded—not reasons invented later Where Section 35 requires recorded reasons, the challenge should focus on the contemporaneous police record. Read the arrest memo, case diary entries, remand application and any statutory checklist together. Do they identify the same reason? Do they contain actual facts? Or do they merely say “for proper investigation” without explaining what custody is supposed to achieve? A reason that can be tested identifies the statutory ground; states the supporting material; connects the material to this accused; explains why custody is needed now; is consistent across arrest and remand papers. A weak boilerplate reason copies all statutory grounds; contains no case-specific fact; uses “proper investigation” as a slogan; does not explain why notice failed; changes materially at remand. The 2026 Supreme Court clarification is especially useful here: the Court described the power of arrest as discretionary, not mandatory, and insisted that the necessity conditions be complied with scrupulously. The investigation cannot use custody merely as a convenient way to ask questions. 5. For offences up to 7 years, notice under Section 35(3) is the rule This is now one of the most important points in the entire arrest framework. In Satender Kumar Antil, 2026 INSC 115 , the Supreme Court expressly concluded that, for offences punishable with imprisonment up to seven years, a notice under Section 35(3) is the rule and arrest is the exception. The notice-first route Complaint / information Accused traceable §35(3) notice Appearance + cooperation Investigation continues without arrest Section 35(4) requires compliance with the notice. Section 35(5) protects a person who complies and continues to comply: that person should not be arrested for the offence mentioned in the notice unless the police officer records reasons for forming the opinion that arrest has become necessary. Major practical point Compliance with notice creates a strong liberty position. Preserve every acknowledgment, appearance memo, email, message, document submission and proof that the accused remained available. Cooperation is not merely a narrative; it should be proved by a chronology. Build a cooperation timeline 1 Notice received Preserve the notice, mode of service and date. 2 Appearance made Keep proof of attendance and statement, if available. 3 Documents supplied Record exactly what was provided and when. 4 Availability maintained Show stable address, employment and continued communication. 5 Arrest nevertheless made Ask what changed after the notice stage. 6. If arrest happens after notice, ask: what new material appeared? The January 2026 Supreme Court order adds an especially powerful practical test. When police arrest under Section 35(6) after the stage of issuing a Section 35(3) notice, the Court said the factors that already existed when the notice was issued should not simply be reused to justify the later arrest. The subsequent arrest should rest on material or factors that were not available when notice was issued. Post-notice arrest stress test Notice issued Accused complies / investigation proceeds New material or new conduct? Only then test necessity of arrest This gives counsel a clean question for cross-record comparison: Ask the investigation file What fact arose after notice that made arrest objectively necessary? If the arrest reasons merely repeat circumstances known before the Section 35(3) notice, highlight the duplication and rely on the Supreme Court's 2026 formulation that post-notice arrest is to be exercised sparingly. Even non-compliance with notice does not automatically compel arrest. The Supreme Court has clarified that arrest is still not a matter of course: necessity must still be evaluated. 7. Audit the arrest procedure itself Even where police claim a lawful power and necessity to arrest, the manner of arrest remains independently important. BNSS retains core procedural safeguards around identification of the arresting officer, preparation of an arrest memorandum, communication of rights, intimation to a nominated person, medical examination and prompt production before the appropriate authority. Date, time and place of arrest documented Arrest memo prepared Arrested person's signature / acknowledgement Required attesting witness details Grounds of arrest communicated Friend / relative informed Medical examination / injury record Access to legal assistance as permitted by law Production before Magistrate without unlawful delay 24-hour constitutional/statutory limit checked Do not lump every procedural defect together. Identify the exact safeguard, the source of the duty, the evidence showing breach and the prejudice or liberty consequence. That gives the court something concrete to decide. File-building rule: photograph or obtain copies of every arrest-related paper as early as lawfully possible. The first few hours often contain the cleanest evidence of compliance or non-compliance. 8. Separate “reasons for arrest” from “grounds of arrest” These expressions are often used loosely, but the litigation function is different. The internal statutory reasons under Section 35 explain why the officer believed arrest was necessary. The constitutional requirement under Article 22(1), read with Section 47 BNSS, concerns communication to the arrested person of why they are being arrested so that they can meaningfully challenge custody and seek legal relief. The Supreme Court's recent arrest jurisprudence has stressed that communication cannot be an empty formality. The grounds must exist before they are communicated, and if an arrested person asserts before court that the grounds were not communicated, the authorities bear the burden of showing compliance. At the same time, Supreme Court decisions have cautioned that the Constitution and BNSS do not invariably prescribe one rigid written format in every ordinary-arrest situation. The safest litigation approach is therefore factual: identify what was communicated, when, in what form, by whom, and whether it meaningfully explained the basis of arrest. Reasons for arrest why custody was necessary; recorded by police; linked to Section 35 criteria; tested by the Magistrate. Grounds communicated why this person is being arrested; must be effectively conveyed; supports immediate legal challenge; Article 22(1) + Section 47 dimension. Do not overstate the law Do not argue that every ordinary BNSS arrest is automatically illegal merely because a separate written “grounds” document was not handed over. Argue the actual constitutional and statutory failure: whether meaningful grounds existed and were effectively communicated in the circumstances, while relying on the binding precedent applicable to the type of arrest involved. 9. Treat the first remand as the first real arrest hearing The legality of arrest should not disappear once the accused reaches the Magistrate. The judicial officer is not meant to mechanically convert police custody into authorised detention. The arrest record, statutory checklist, necessity material and procedural compliance should be examined before remand is granted. First-remand challenge brief Issue What defence should place on record Offence + punishment Correct punishment bracket and applicable Section 35 route. Reason to believe Whether real material, not merely accusation, is identified. Necessity Why each claimed statutory ground is unsupported or manageable by conditions. Notice / cooperation Notice, replies, appearances, document submissions and availability. Arrest procedure Memo, intimation, grounds communicated, medical record and timing. Custody purpose What recovery, confrontation, protection or investigative step truly needs custody. Ask for a reasoned judicial decision. If police say custody is needed for “proper investigation,” require them to identify the investigative act that cannot reasonably occur without custody. If recovery is cited, identify the precise object or information still outstanding. If witness influence is cited, ask for the material supporting that risk. The remand court should test necessity, not merely confirm that an arrest has already happened. 10. Build an illegal-arrest challenge bundle The strongest challenge is document-driven. Create one indexed bundle that allows the court to understand the arrest issue without searching through the entire police file. 01 FIR / complaint The allegation actually made, sections invoked and dates. 02 Offence-and-punishment chart Cognizable status, punishment and Section 35 route. 03 Notice + cooperation record Section 35(3) notice, replies, appearance proof and document submissions. 04 Recorded-reasons comparison Case diary, arrest memo, checklist and remand application placed side by side. 05 Arrest safeguards Memo, grounds communication, relative intimation, medical papers and timing. 06 First remand record Remand request, defence objections and judicial order. 07 Objective liberty material Residence, employment, passport/travel facts, prior appearances and anything disproving flight or obstruction risk. One-page working order Section → Reason to believe → Necessity → Notice → Recorded reasons → Safeguards → Remand → Relief. That order keeps the challenge technical. It prevents the hearing from becoming an argument about whether the accused is generally “good” or “bad” and keeps the court focused on whether the statutory conditions for taking away liberty were actually met.

Visit store.theedulaw.in Frequently asked questions Is arrest mandatory merely because a cognizable FIR is registered? No. Section 35 uses a structured arrest framework, and the Supreme Court has repeatedly emphasised that the existence of a power to arrest does not make arrest automatic. For the up-to-seven-year category, the 2026 Supreme Court order expressly described arrest as discretionary rather than mandatory. Is notice under Section 35(3) mandatory for every offence up to seven years? The Supreme Court in Satender Kumar Antil, 2026 INSC 115, stated that for offences punishable with imprisonment up to seven years, Section 35(3) notice is the rule, while arrest under Section 35(6) read with Section 35(1)(b) is the exception. Can police arrest a person who complied with a Section 35(3) notice? Section 35(5) protects a person who complies and continues to comply. Arrest thereafter requires recorded reasons. The 2026 Supreme Court clarification further says that a later arrest should be based on new material or factors not already available at the notice stage. Does failure to comply with notice automatically require arrest? No. The Supreme Court has clarified that even non-compliance does not make arrest automatic. The investigating agency still has to exercise discretion and assess necessity. What is the most useful document in an illegal-arrest challenge? There is no universal single document. In practice, the strongest bundle usually combines the offence/punishment chart, Section 35 notice history, proof of cooperation, written arrest reasons, arrest memo and the first remand application/order.
