Mumbai Criminal Courts & Remand Guide: Magistrate Proceedings, Police Custody and Bail Under BNSS

When an individual is arrested by police in Mumbai, the first 24 to 48 hours represent the most decisive window in the criminal justice process. The transition from the police station lockup to the courtroom of a Metropolitan Magistrate marks the shift from administrative detention to judicial scrutiny. Understanding how remand hearings operate, the vital distinction between police custody and judicial custody, and the multi-tiered structure of Mumbai's criminal courts under the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) is essential for accused persons and their families seeking to safeguard personal liberty.

1. The Arrest-to-Court Transition: The 24-Hour Production Mandate

Under Article 22(2) of the Constitution of India and Section 58 of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) (formerly Section 57 of the Code of Criminal Procedure), no police officer may detain in custody a person arrested without a warrant for a longer period than under all circumstances of the case is reasonable. In the absence of a special order of a Magistrate under Section 187 BNSS, such detention cannot exceed 24 hours.

The Journey Time Rule: The only statutory exclusion from this strict 24-hour ceiling is the time necessary for the journey from the place of arrest to the Magistrate's Court. If the journey time is unduly prolonged without concrete justification, or if the accused is held in an unrecorded lockup or transit without being entered into the general diary, such detention is constitutionally impermissible.

For immediate on-ground legal protection during these critical pre-production hours—including monitoring the arrest memo and ensuring compliance with mandatory medical examination under Section 53 BNSS—families frequently engage an emergency Mumbai police station visit advocate.

2. Inside the Courtroom: What Happens at the Initial Remand Hearing

Upon producing the arrested person before the jurisdictional Magistrate, the investigating officer (IO) submits a formal remand application, colloquially termed a Remand Yadi in Maharashtra practice. This document outlines:

▪
The sections of the Bharatiya Nyaya Sanhita, 2023 (BNS) or special penal statutes invoked in the First Information Report (FIR).
▪
The role attributed to the accused in the alleged offence.
▪
The specific grounds on which the police seek physical custody (e.g., recovery of weapons or stolen articles, forensic analysis of electronic devices, confrontation with co-accused, or unearthing a wider conspiracy).

The Magistrate's Judicial Scrutiny

A remand hearing is not an administrative rubber-stamping exercise. The Magistrate has a judicial obligation under Section 187 BNSS to:

Ascertain whether the accused was informed of the grounds of arrest and their legal rights under Section 47 BNSS.
Inquire into any physical mistreatment or torture while in police lockup, verifying the official medical report.
Peruse the Case Diary maintained under Section 192 BNSS to satisfy themselves that genuine, credible grounds exist warranting further detention.
Afford the accused or their defence advocate an opportunity to be heard and oppose the remand application.

3. Police Custody (PC) vs. Judicial Custody (JC): Legal and Practical Differences

When a Magistrate decides to authorize detention under Section 187 BNSS, they must determine whether to remand the accused to Police Custody or Judicial Custody. The difference between these two custodial regimes is profound:

Custody Feature	Police Custody (PC)	Judicial Custody (JC)
Physical Location	Police station lockup or crime branch detention cell.	State correctional prison (e.g., Arthur Road Jail or Byculla Jail in Mumbai).
Direct Supervision	Under direct physical control of the Investigating Officer (IO).	Under the custody of the Magistrate, managed by the Jail Superintendent.
Primary Purpose	Active interrogation, evidence recovery, and discovery of facts.	Safe custody pending trial; preventing witness tampering or flight risk.
Interrogation Rules	Police may interrogate continuously subject to statutory human-rights guidelines.	Police cannot interrogate without prior written permission and directions from the court.
Bail Strategy	Advocate vigorously opposes police custody remand, seeking immediate JC or interim bail.	Regular bail application is argued on merits before the competent Magistrate or Sessions Court.

In Mumbai criminal practice, experienced defence counsel focus heavily on demonstrating that custodial interrogation is superfluous—for instance, where all material documents are already in the police's possession or where the offence does not involve physical recovery—urging the court to send the accused directly to judicial custody.

4. Section 187 BNSS: Custody Limits, Timing, and Statutory Bail

The enactment of Section 187 BNSS introduced vital modifications to the erstwhile remand architecture under Section 167 of the CrPC. Key structural dimensions include:

A. The 15-Day Police Custody Ceiling and the "In Parts" Mechanism

Under former Section 167(2) CrPC, as settled by the Supreme Court in CBI v. Anupam J. Kulkarni (1992), police custody was strictly limited to the first 15 days following arrest. If an accused was sent to judicial custody, police custody could not be sought thereafter.

Under Section 187(3) BNSS, the Magistrate may authorize detention in police custody for a term not exceeding 15 days in the aggregate, which may now be granted in the whole, or in parts, at any time during the initial forty days (for 60-day investigation matters) or sixty days (for 90-day investigation matters). However, police custody is not an automatic entitlement for 15 days; the investigating agency must independently justify every tranche with fresh, tangible investigative requirements.

B. The 60-Day and 90-Day Investigation Limits (Default Bail)

The total period of detention during investigation (combining police and judicial custody) cannot exceed:

90 Days: Where the investigation relates to an offence punishable with death, imprisonment for life, or imprisonment for a term of not less than 10 years.
60 Days: Where the investigation relates to any other non-bailable offence.

If the investigating agency fails to complete its investigation and file a chargesheet (police report) within this prescribed statutory period, the accused acquires an indefeasible, constitutional right to release on default bail under the Proviso to Section 187(3) BNSS upon furnishing bail. To understand the mechanics of filing such petitions, review our specialized guide on statutory default bail under Section 187(3) BNSS and our statutory analysis of default bail rights in India.

C. Distinguishing Section 187 Default Bail from Section 479 Undertrial Detention

It is crucial not to confuse default bail under Section 187(3) with Section 479 BNSS (formerly Section 436A CrPC). While Section 187(3) deals strictly with the police failure to file a chargesheet within 60 or 90 days of arrest, Section 479 applies to undertrial prisoners whose trial or inquiry is ongoing, mandating release on a personal bond if they have undergone detention extending up to one-half (or one-third for first-time offenders) of the maximum statutory sentence prescribed for that offence.

5. The Institutional Hierarchy of Criminal Courts in Mumbai

Mumbai possesses a multi-layered criminal judicial system structured across metropolitan districts. The specific court handling an accused's remand and bail depends on the stage of proceedings, the seriousness of the offence, and administrative jurisdictional notifications:

1. Metropolitan Magistrate Courts

Headed by the Chief Metropolitan Magistrate (CMM), with courts across Esplanade, Bandra, Andheri, Borivali, Kurla, Mazgaon, Girgaon, Dadar, Vikhroli, and Mulund.

Jurisdiction: Initial remand under Section 187 BNSS, bailable offences, trials of offences punishable with imprisonment up to 3 years (or 7 years for Chief Metropolitan Magistrates), and regular bail under Section 480 BNSS.

2. Court of Session (Sessions Courts)

The City Civil & Sessions Court at Fort (Greater Mumbai) and the Mumbai Suburban District Sessions Court at Dindoshi (Goregaon East).

Jurisdiction: Trials for serious offences punishable with 7+ years, life imprisonment, or death; anticipatory bail applications under Section 482 BNSS; and regular bail applications under Section 483 BNSS.

3. The Bombay High Court (Principal Seat)

Located at Fort, Mumbai, holding appellate, revisionary, and supervisory constitutional jurisdiction over all lower criminal courts in Maharashtra.

Jurisdiction: Concurrent special bail powers under Section 483 BNSS; inherent powers to quash false proceedings under Section 528 BNSS; and writ jurisdiction under Articles 226 and 227 of the Constitution.

6. How Regular Bail Applications Proceed: Magistrates, Sessions, and High Court

Securing release once a person has been remanded to custody requires initiating a regular bail application under Section 480 or Section 483 BNSS. It is essential to distinguish this from pre-arrest relief:

▪
Anticipatory Bail (Section 482 BNSS): Sought before arrest when an individual reasonably apprehends arrest in a non-bailable matter, filed directly before the Sessions Court or the High Court. Read our comprehensive analysis on the distinction between regular and anticipatory bail under BNSS or consult our anticipatory bail representation.
▪
Section 35 BNSS Police Notices: In offences punishable with up to 7 years imprisonment, police must ordinarily issue a notice of appearance rather than effecting arrest, unless statutory necessity is documented. Learn how to address these notices through our Section 35 BNSS police notice guidance.
▪
Regular Bail (Section 480 & 483 BNSS): Sought after an arrest has occurred and the accused is in custody, filed initially before the Magistrate or Sessions Court. For complete service details, see our regular bail legal representation in Mumbai.

Procedural Posture: Approaching the Bombay High Court Under Section 483 BNSS

A common misconception is that approaching the Bombay High Court after a bail rejection by a Magistrate or Sessions Judge constitutes a "statutory appeal." In criminal jurisprudence, this is legally inaccurate.

Under Section 483 BNSS (replacing Section 439 CrPC), the High Court exercises special, concurrent original jurisdiction regarding bail. Moving the High Court is an independent substantive application where counsel demonstrates why liberty should be granted—such as parity with co-accused, absence of flight risk, extensive delay in trial, completion of investigation, or prolonged undertrial incarceration. Explore our dedicated page on High Court bail proceedings in Mumbai.

7. Special Courts and Statutory Exceptions in Mumbai

When an FIR involves special penal statutes, the standard bail provisions under Section 480 and 483 BNSS are modified by stringent statutory embargoes, and proceedings are assigned to designated Special Courts:

▪
Narcotic Drugs and Psychotropic Substances (NDPS) Act: Remand and trial are conducted before Special NDPS Courts (located at Sessions Court, Fort). For commercial quantities, bail is subject to the stringent Section 37 twin conditions, requiring the court to be satisfied of reasonable grounds for believing the accused is not guilty. Read our in-depth guide on NDPS bail procedure in Mumbai.
▪
Maharashtra Control of Organised Crime Act (MCOCA): Handled by Special MCOCA Courts at Arthur Road / Sessions Court. Under Section 21(4) MCOCA, pre-trial bail is subject to heightened statutory bars similar to NDPS commercial matters.
▪
CBI, POCSO, and PMLA Courts: Dedicated designated special judges at the Sessions Court complex handle cases involving central investigation agencies, child protection legislation, and money-laundering allegations.

8. Why the Police Station Alone Does Not Determine Court Jurisdiction

Families often assume that the police station investigating the matter automatically dictates which court will hear every subsequent application. This assumption is legally incorrect:

Administrative Magisterial Rosters: Remand jurisdiction is assigned based on administrative notifications issued by the Chief Metropolitan Magistrate (CMM), Esplanade, assigning specific police stations to designated Additional Chief Metropolitan Magistrates (ACMMs) or Metropolitan Magistrates (MMs). These rosters are administrative and subject to periodic redistribution.
Committal to Sessions: If an offence is triable exclusively by the Court of Session (such as Section 103 BNS for murder), the Magistrate's role is restricted to initial remand and committal under Section 232 BNSS; regular bail applications must be moved before the Sessions Court.
Specialised City-Wide Investigative Branches: Specialized squads—such as the Economic Offences Wing (EOW), Crime Branch, or Regional Cyber Crime Police Stations—hold city-wide investigation jurisdiction across Mumbai, but their matters are assigned to designated special Magistrate or Sessions courts.
Concurrent High Court Access: An accused may approach the High Court under Section 483 BNSS or invoke inherent powers under Section 528 BNSS regardless of which local police station initiated the FIR.

9. Practical Checklist for Families: Critical Records and Questions to Ask

If a family member has been arrested or summoned in Mumbai, securing essential judicial records immediately is vital for building an effective bail defence:

Essential Records to Obtain & Preserve

Certified or official copy of the First Information Report (FIR).
Arrest Memo indicating exact date, time, and witnesses to arrest.
Official Medical Examination Report prepared under Section 53 BNSS.
Copy of the Police Remand Application (Remand Yadi).
The formal Magisterial Remand Order specifying PC or JC duration.
Identity, residence, and financial solvency documents of proposed sureties.

Questions to Discuss with Your Criminal Advocate

What specific investigative necessity does the IO cite for police custody?
Were the grounds of arrest communicated in writing to the family?
Can we argue for immediate judicial custody at the first production?
Which court holds territorial jurisdiction for regular bail (MM vs Sessions)?
What surety requirements will the court impose once bail is granted?

Once bail is ordered, completing release formalities without delay requires local surety scrutiny, solvency certificates, and Parwana verification. Review our step-by-step guide on surety verification and court release documentation.

10. Frequently Asked Questions: Mumbai Criminal Remand & Courts

Q1: Can police interrogate an accused once they are remanded to judicial custody?

No. Once an accused is remanded to judicial custody (in prison), the police have no unrestricted access to interrogate them. To interrogate an undertrial in prison, the investigating officer must file a formal application before the jurisdictional Magistrate seeking permission and establishing cogent grounds.

Q2: What happens if the police fail to produce the accused before a Magistrate within 24 hours?

Detention beyond 24 hours (excluding journey time) without a Magisterial remand order is illegal and violates Article 22(2) of the Constitution. Defence counsel can immediately move a habeas corpus petition or challenge the legality of detention before the duty magistrate, potentially seeking immediate release or compensation.

Q3: Can a Metropolitan Magistrate grant bail in offences triable exclusively by the Court of Session?

Under Section 480(1) BNSS, a Magistrate cannot ordinarily grant bail if there appear reasonable grounds for believing that the accused has been guilty of an offence punishable with death or imprisonment for life, or where the person has previous convictions for serious offences, unless statutory exceptions (women, minors, sickness, infirmity) apply. For offences exclusively triable by Sessions, standard practice in Mumbai is to seek bail before the Sessions Court under Section 483 BNSS.

Q4: If the Sessions Court rejects bail, is the next step an appeal to the Bombay High Court?

Approaching the Bombay High Court after a Sessions Court rejection is not a statutory appeal; it is a fresh, substantive bail application filed under the concurrent powers of Section 483 BNSS. The High Court examines the matter independently on merits, evaluating the overall balance between personal liberty and the integrity of the trial.

Q5: Does Section 187 BNSS guarantee the police 15 days of police custody in every case?

No. 15 days is the statutory maximum ceiling, not an entitlement. Remand to police custody is an exception to the general rule of judicial custody. The Magistrate must independently assess whether custodial interrogation is indispensable or whether the investigation can proceed without lockup detention.
