In India’s criminal justice system, the most decisive moment rarely occurs during trial or judgment. It occurs much earlier — at the point of arrest. It is here that State power confronts individual liberty in its most direct form. For decades, this confrontation was governed by the Code of Criminal Procedure, 1973. From 1 July 2024, that framework stands replaced by the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS).
The transition has not rewritten criminal procedure overnight. Instead, it has absorbed decades of constitutional interpretation into statutory form, particularly in matters of arrest, custody, and bail — areas where misuse has historically attracted the sharpest judicial scrutiny.
Arrest: Authority Bound by Necessity
The power of arrest continues to flow from the police’s authority to investigate cognisable offences under BNSS, much as it did under the CrPC. However, the BNSS places renewed emphasis on the principle that arrest is not mandatory merely because an offence is registered.
This approach reflects the Supreme Court’s reasoning in Joginder Kumar v. State of Uttar Pradesh (1994), where the Court held that arrest must be justified by necessity and cannot be a routine response to an allegation. That principle was later strengthened in Arnesh Kumar v. State of Bihar (2014), particularly in offences punishable with imprisonment up to seven years, where the Court warned against mechanical arrests and insisted on reasoned satisfaction.
The BNSS internalises this judicial caution. Arrest under the new law is explicitly tied to investigative necessity — preventing absconding, ensuring cooperation, safeguarding evidence, or addressing the seriousness of the offence. The assumption that arrest is a natural consequence of accusation finds little support in the statute’s design.
Safeguards accompanying arrest remain constitutionally anchored. An arrested person must be informed of the grounds of arrest, a requirement flowing directly from Article 22(1) of the Constitution. Communication with a friend or relative, preparation of an arrest memo, and medical examination are not procedural formalities but legal obligations shaped by the Supreme Court’s ruling in D.K. Basu v. State of West Bengal (1997).
What BNSS changes is not the existence of safeguards, but the expectation of compliance.
Custody and Judicial Oversight
Once arrest occurs, the law’s focus shifts decisively from police authority to judicial supervision. Under BNSS, as under the CrPC, custody exists in two forms — police custody and judicial custody — each serving distinct purposes.
Police custody is intended to facilitate investigation and interrogation, while judicial custody places the accused beyond the immediate control of the investigating agency. The power to authorise either lies exclusively with the Magistrate, reinforcing the judiciary’s role as the constitutional gatekeeper of liberty.
The BNSS retains the requirement that an arrested person must be produced before a Magistrate within twenty-four hours, in keeping with Article 22(2). What is more pronounced under the new law is the insistence that custody orders must be reasoned. Requests for police custody are no longer meant to be extensions granted by default, but decisions grounded in necessity and proportionality.
The Supreme Court has repeatedly warned against the casual grant of police custody, recognising its potential for abuse. In CBI v. Anupam J. Kulkarni (1992), the Court clarified limits on police custody and emphasised judicial vigilance. BNSS echoes this jurisprudence, treating custody as an exception rather than a norm.
Time-bound investigation remains central. Statutory limits on detention without filing a charge-sheet continue, and failure to comply triggers the right to default bail, a safeguard recognised as flowing from Article 21 by the Supreme Court in Rakesh Kumar Paul v. State of Assam (2017).
Bail: Liberty as the Starting Point
If arrest and custody reflect the State’s coercive power, bail reflects its constitutional restraint. The BNSS retains the familiar structure of bail — regular bail, anticipatory bail, and default bail — but places them within a jurisprudence that increasingly views pre-trial detention with scepticism.
The principle that “bail is the rule and jail the exception”, articulated in State of Rajasthan v. Balchand (1977) and reaffirmed in Sanjay Chandra v. CBI (2012), continues to guide judicial discretion. Courts assessing bail under BNSS are expected to balance the seriousness of the offence against the presumption of innocence, the likelihood of absconding, and the possibility of influencing witnesses.
The BNSS does not dilute the right to anticipatory bail, a remedy rooted in personal liberty and judicial foresight. Nor does it weaken the consequences of investigative delay, where prolonged detention without progress remains constitutionally suspect.
What the law demands, increasingly, is reasoned adjudication. Bail is no longer a matter of judicial instinct alone; it is an exercise in constitutional balancing.
Procedure as a Constitutional Instrument
The deeper significance of BNSS lies not in procedural novelty but in constitutional consolidation. For decades, Indian courts used Article 21 to read fairness, reasonableness, and proportionality into criminal procedure. The BNSS absorbs much of that interpretative legacy into statutory form.
This shift matters. A safeguard rooted only in precedent depends on awareness and enforcement. A safeguard written into the statute demands compliance as a matter of legal duty.
The law also acknowledges structural realities — overcrowded prisons, delayed trials, and investigative inertia. By reinforcing timelines and judicial oversight, BNSS attempts reform without destabilising the criminal justice system.
What Changes — and What Doesn’t
For citizens, the lived experience of criminal law may not transform overnight. Arrests will still occur, custody will still be sought, and bail will still be contested. But the legal framework governing these processes has narrowed discretion and strengthened accountability.
Arrest is more clearly linked to necessity. Custody is more visibly supervised. Bail is more firmly anchored in constitutional logic.
These changes are incremental, not revolutionary. But in criminal procedure, incremental change often has the most lasting impact.
Conclusion
The BNSS represents continuity shaped by constitutional correction. It does not dismantle State power, nor does it romanticise liberty. Instead, it attempts to discipline authority through procedure.
Arrest, bail, and custody remain the sharp edges of criminal law. Under the BNSS, those edges are still present — but they are now bound more tightly to constitutional restraint, judicial oversight, and reasoned exercise of power.
Whether this recalibration succeeds will depend less on statutory text and more on institutional behaviour — in police stations, remand courts, and bail hearings across the country.
The law has changed. The real test lies in how faithfully liberty is protected when the State chooses to act.
