The transition from the Code of Criminal Procedure, 1973 (CrPC) to the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) has not altered the constitutional architecture governing arrest. Rather it has, for the first time, codified into statutory text a body of safeguards that previously existed only as judicial directions scattered across decades of Supreme Court jurisprudence. For legal practitioners, the exercise is no longer one of reading Article 22 alongside landmark judgments such as D.K. Basu and Arnesh Kumar as extra-statutory glosses on the CrPC. It is now a matter of locating the precise BNSS provision that operationalises each constitutional guarantee, and assessing how the existing case laws map onto or extend beyond that provision. This becomes particularly significant at the remand stage, where a Magistrate’s failure to apply these safeguards can itself become a ground for challenge independent of the merits of the underlying accusation of the alleged crime.
Article 21 of the Constitution remains the residual guarantee against deprivation of liberty without procedure established by law. However, it is Article 22 (1) and (2) that supply the operative content for arrest jurisprudence: the right to be informed of the grounds of arrest “as soon as may be,” the right to consult and be defended by a legal practitioner of choice, and the requirement of production before the nearest Magistrate within 24 hours, exclusive of travel time. The Supreme Court’s holding in D.K. Basu v. State of West Bengal (1997) translated these guarantees into eleven operational directions : (1) Visible identification of the arresting officer; (2) Preparation of an arrest memo attested by a family member or local witness and countersigned by the arrestee; (3) The right to have next of Kin, a friend or relative informed of the arrest and the place of detention; (4) If the next of kin/relative resides outside the concerned district then sending them time bound telegraphic notices informing about time, place of arrest and venue of detention; (5) Informing the arrestee of their rights; (6) Case diary entry containing the information of the next of kin/relative who was informed about the arrest; (7) Initial medical inspection with contemporaneous recording of injuries via an Inspection Memo; (8) Periodic medical examination at 48 hour intervals; (9) Forwarding copies of all crucial arrest documentation including Memo of Arrest and Inspection Memo to nearest Magistrate concerned; (10) Right of the arrestee to meet legal practitioner of choice during interrogation; (11) Establishment of Police Control Rooms and PCR Notice Boards – all issued as binding directions under Article 141. Yet for over a quarter-century these survived as a parallel compliance regime rather than as part of the CrPC’s text, a structural gap that frequently allowed enforcement to be treated as aspirational rather than mandatory.
Arnesh Kumar v. State of Bihar (2014), addressed a different but related defect i.e. the routine, at times reflexive, use of arrest powers under Section 41 CrPC in cases paradigmatically Section 498A IPC and Section 4 of the Dowry Prohibition Act, 1961 where the prescribed punishment did not necessitate custodial interrogation after any rational assessment. The Court’s direction that police officers record reasons in writing against the checklist parameters of Section 41(1)(b)(ii), and that a notice under Section 41A be issued in lieu of arrest wherever the threshold for arrest under Section 41(1)(b)(i) is not independently satisfied, effectively converted arrest from a default investigative step into a measure requiring affirmative justification for any offence punishable with imprisonment up to seven years. Equally significant, and often under-litigated, is the second limb of Arnesh Kumar judgment: the obligation cast on the Magistrate not to authorise detention under Section 167 CrPC mechanically, but to record satisfaction that the police’s reasons meet the statutory threshold, a duty whose breach renders the remand order itself amenable to challenge, independent of any infirmity in the arrest.
The BNSS now embeds both lines of authority directly into the statutory scheme, and the cross-referencing is where the practical value to a litigator lies. Section 35 BNSS substantially reproduces Section 41/41A CrPC, retaining the Arnesh Kumar architecture i.e. notice of appearance as the default for offences carrying sentences of seven years or less, and arrest as the exception requiring recorded justification. While Section 35(7) introduces a fresh safeguard absent from the CrPC altogether, requiring prior permission from a Deputy Superintendent of Police before arresting an infirm or elderly person for an offence punishable with less than three years’ imprisonment. Section 36 BNSS codifies the D.K. Basu identification and arrest-memo requirements verbatim into statute, removing any argument that these remain merely persuasive guidelines. Section 47 BNSS replaces Section 50 CrPC and gives Article 22(1) its statutory expression, obliging the arresting officer to communicate the full particulars of the offence and the grounds of arrest. This provision now has to be read alongside Pankaj Bansal v. Union of India (2023) where the Supreme Court in the context of arrests under the Prevention of Money Laundering Act, 2002 held that the grounds of arrest must be furnished in writing rather than communicated orally, a requirement subsequently extended in 2024 to arrests under the Bharatiya Nyaya Sanhita and the erstwhile IPC. Sections 38 and 48 BNSS preserve the qualified right to consult legal practitioner during interrogation and the right to have a relative or friend informed of the place of detention, both traceable to Article 22(1) and the D.K. Basu guideline. While the BNSS’s enhanced protections for women i.e. restricting arrest between sunset and sunrise absent prior permission of a Judicial Magistrate of the First Class, and mandating that the arrest itself be effected by a female officer go beyond what either D.K. Basu or Arnesh Kumar required, reflecting a distinct legislative policy choice rather than mere codification.
For remand practice, Section 187 BNSS, the successor to Section 167 CrPC, must now be read in conjunction with Section 35: a Magistrate considering an application for detention is not merely checking whether the statutory period for filing a chargesheet has lapsed, but is independently obligated to satisfy itself that the arrest itself complied with the Section 35 checklist and that the grounds furnished under Section 47 meet the written-disclosure standard set out in Pankaj Bansal. A remand order passed without this scrutiny is vulnerable to challenge on the authority of Arnesh Kumar’s second limb, regardless of whether the arrest itself is separately impugned. This gives two independent avenues of attack on an improper detention: the legality of the arrest under Sections 35, 36, and 47 BNSS, and the legality of the remand order under Section 187, and the Magistrate’s Arnesh Kumar obligations. The two should be pleaded distinctly, since a defect in the latter does not require a finding on the former.
A further point of doctrinal interest is the interplay between Section 35(7) BNSS and the existing protective framework for vulnerable categories of accused persons. While the CrPC contained no analogous provision requiring a senior officer’s sanction before arresting an infirm or elderly person for a low-threshold offence, the BNSS now treats this as a distinct procedural precondition, comparable in structure, though not in source, to the special timing and gender restrictions applicable to the arrest of women. The absence of such sanction, where it was statutorily required, ought logically to be treated on the same footing as non-compliance with the Section 35(1) checklist for purposes of challenging the legality of the arrest, though this is a proposition that will require judicial elaboration as litigation under the BNSS matures. Equally, the written-grounds requirement from Pankaj Bansal, having been extended beyond its originating PMLA context to general criminal law, now operates as a near-universal evidentiary threshold: an arrest memo or grounds document that merely recites the statutory language of the offence, without disclosing the material facts that led the officer to form the requisite belief under Section 35(1), is unlikely to satisfy either Section 47 BNSS or the constitutional standard under Article 22(1). It would be prudent to scrutinise the grounds document on this basis as a matter of course rather than as an afterthought.
Where these safeguards are found wanting, the remedial architecture remains rooted in Articles 32 and 226: a habeas corpus petition challenging the legality of continued detention, or a writ challenging the remand order itself, remains available notwithstanding the existence of statutory remedies such as bail or revision, particularly where the illegality goes to the root of the detention rather than to its conditions. The codification under the BNSS does not displace this constitutional remedy, it merely sharpens the grounds on which it can be invoked by converting what were previously arguments rooted in judicially-evolved “guidelines” into arguments rooted in non-compliance with the texts of codified penal & procedural laws: a distinction that in practice considerably strengthens the hand of a party seeking interim relief.
The practical takeaway is that the BNSS has not diluted the D.K. Basu and Arnesh Kumar safeguards by codifying them. Codification raises the stakes for non-compliance, since a deviation from a statutory provision is more readily characterised as an illegality than a deviation from a judicial guideline ever was. At the remand stage, in bail applications, or in detention-challenge petitions, Sections 35, 36, 47, 48, and 187 BNSS should be treated as the primary text, with D.K. Basu, Arnesh Kumar, and Pankaj Bansal as the interpretive lens through which legality of the arrest/remand is assessed and argued.
