BharatNotes Note: This chapter was removed from the NCERT curriculum in the 2022 rationalization. Retained here as criminal justice institutions — police, courts, prisons, legal aid — are GS2 governance topics.
Why this chapter matters for UPSC: Criminal justice reform is a recurring GS2 theme covering governance, polity, and social justice. Topics like the FIR process, rights of the accused (Articles 20–22), DK Basu guidelines, prison overcrowding, and the shift from CrPC to BNSS 2023 directly appear in Prelims and Mains. Legal aid (Article 39A + NALSA) and prison reform (Model Prison Act 2023) are high-value contemporary issues.
PART 1 — Quick Reference Tables
Four Pillars of the Criminal Justice System
| Institution | Role | Key Law / Provision |
|---|---|---|
| Police | Investigate crime; register FIR; arrest; file charge sheet | CrPC / BNSS 2023; DK Basu Guidelines 1997 |
| Public Prosecutor | Represent State in criminal court; duty to ensure fair trial | Article 165 (Advocate General for State) |
| Defence Lawyer | Represent accused; ensure fair trial | Article 22(1); Legal Services Authorities Act 1987; NALSA |
| Magistrate / Judge | Remand; bail; trial; sentencing; acquittal or conviction | CrPC / BNSS; Indian Evidence Act → BSA 2023 |
Rights of the Accused — Constitutional Provisions
| Article | Right | Key Detail |
|---|---|---|
| Article 20(1) | No ex post facto law | Cannot be punished under a law that did not exist when the act was committed |
| Article 20(2) | No double jeopardy | Cannot be tried/punished for the same offence twice |
| Article 20(3) | No self-incrimination | Cannot be compelled to be a witness against oneself |
| Article 21 | Right to life and personal liberty | Arrested person must be produced before magistrate within 24 hours |
| Article 22(1) | Right to be informed of grounds of arrest | Right to consult a lawyer of one's choice |
| Article 22(2) | Produced before magistrate within 24 hours | Protects against illegal detention |
| Article 39A | Free legal aid (DPSP) | Basis for Legal Services Authorities Act 1987 and NALSA |
Criminal Trial Process — Stages
| Stage | Key Detail |
|---|---|
| FIR (First Information Report) | Must be registered for cognizable offences; FIR refusal → complaint to magistrate |
| Investigation | Police gather evidence; 60/90 days to file charge sheet (BNSS 2023) |
| Arrest & Remand | Remand max 14 days at a time; magistrate can extend to 90 days for serious offences |
| Charge Sheet | Filed in court; cognizable offences → Sessions Court (serious) or Magistrate Court |
| Trial | Charges framed → examination of witnesses → arguments → judgment |
| Conviction / Acquittal | Sentence (imprisonment, fine) or acquittal; both parties can appeal |
PART 2 — Detailed Notes
The Police and FIR
An FIR (First Information Report) is the document that sets the criminal justice process in motion. It must be registered by the police for every cognizable offence (an offence for which police can arrest without a warrant — e.g., murder, robbery, rape). Refusing to file an FIR is illegal; the complainant can approach a magistrate, who can direct the police to register it. A copy of the FIR must be given free of charge to the complainant.
Under the Bharatiya Nagarik Suraksha Sanhita (BNSS) 2023 — which replaced the Code of Criminal Procedure (CrPC) 1973 — the time limit for filing a charge sheet remains 60 days for offences punishable up to 3 years and 90 days for serious offences. Failure to file within this period entitles the accused to bail.
DK Basu Guidelines (1997)
UPSC GS2 — Police Reforms: In D.K. Basu v. State of West Bengal (1997), the Supreme Court laid down mandatory guidelines for arrest and detention to prevent custodial torture and deaths:
- Arresting officer must display name badge
- Arrest memo must be prepared and attested by a family member or witness
- Arrested person must be medically examined every 48 hours
- Family/friend of arrested person must be informed promptly
- Right to meet a lawyer during interrogation These were given statutory backing via the CrPC Amendment 2010. Violation can lead to contempt of court. Custodial deaths are a persisting governance failure — NHRC receives the highest complaints from UP, Maharashtra, and Bihar.
The Public Prosecutor
The Public Prosecutor represents the State (not the victim) in a criminal trial. Their duty is to place all evidence — including evidence favourable to the accused — before the court. This reflects the principle that the State seeks justice, not vengeance. In the Supreme Court, Amicus Curiae (friend of the court) lawyers assist in cases involving complex legal questions or unrepresented parties.
The Defence Lawyer and Legal Aid
Article 22(1) guarantees every arrested person the right to consult a lawyer. Article 39A (DPSP) directs the State to ensure that equal justice is not denied due to poverty. The Legal Services Authorities Act 1987 operationalises this, creating:
- NALSA (National Legal Services Authority) — chaired by the Chief Justice of India as Patron-in-Chief; a sitting SC judge as Executive Chairman
- SLSAs (State Legal Services Authorities) — at state level
- DLSAs (District Legal Services Authorities) — at district level Free legal aid is available to: women, children, SC/ST persons, persons with disabilities, industrial workmen, persons in custody, and those with annual income below ₹1 lakh (central limit; states vary).
Bail and Anticipatory Bail
Bail is the temporary release of an accused pending trial. For bailable offences, bail is a right. For non-bailable offences, bail is at the magistrate's discretion. Conditions may be attached (e.g., surrendering passport, reporting to police station).
Anticipatory bail (Section 438 CrPC → Section 482 BNSS 2023) is granted by the Sessions Court or High Court to a person who anticipates arrest. It must be applied for before arrest. The court considers the nature and gravity of the accusation, prior criminal record, and possibility of fleeing.
UPSC GS2 — Criminal Law Reforms: The three new criminal laws enacted in 2023 — Bharatiya Nyaya Sanhita (BNS), Bharatiya Nagarik Suraksha Sanhita (BNSS), and Bharatiya Sakshya Adhiniyam (BSA) — replaced the Indian Penal Code 1860, CrPC 1973, and Indian Evidence Act 1872 respectively. Key changes: terrorism and organised crime defined; trials via video-conferencing allowed; 90-day time limit for investigation in serious cases; electronic records as primary evidence. Critics argue the laws replicate colonial provisions without substantive reform.
Presumption of Innocence and Fair Trial
A cornerstone of criminal justice: the accused is presumed innocent until proven guilty beyond reasonable doubt. The burden of proof lies with the prosecution. Conviction on suspicion alone is constitutionally impermissible. This flows from Article 21 (right to life and personal liberty).
Prison Reform
India has approximately 1,319 prisons (NCRB Prison Statistics 2022) with a sanctioned capacity of ~4.25 lakh but housing ~5.73 lakh inmates — an occupancy rate of 131.4%, reflecting severe overcrowding. Most alarmingly, undertrials constitute ~75.8% of the prison population — meaning most prisoners have not been convicted of any crime. This violates the right to personal liberty under Article 21.
Key reform initiatives:
- Model Prison Act 2023 — replaced the archaic Prisons Act 1894; focuses on rehabilitation, education, skill development, and open prisons
- Open Prisons (Rajasthan model): Prisoners allowed to live with families in a semi-free environment; reduces recidivism
- Fast-track courts for undertrials under Section 436A CrPC (BNSS equivalent): Release after serving half the maximum sentence (for non-death penalty offences) as undertrial
- Bail reforms: Law Commission 268th Report (2017) recommended a separate Bail Act to reduce undertrial detention
[Additional] 6a. Undertrial Reform — Section 479 BNSS, Bhim Singh (2014), and Arnesh Kumar Guidelines
The chapter mentions Section 436A CrPC briefly but does not cover the Bhim Singh SC directive (2014) that operationalised it, the BNSS 2023 change (one-third threshold for first-time offenders), or Arnesh Kumar (2014) guidelines limiting arrest powers.
Key Terms — Bail and Undertrial Reform:
| Term | Meaning |
|---|---|
| Section 436A CrPC / Section 479 BNSS | An undertrial who has served half the maximum imprisonment for the offence may be released on bail; Section 479 BNSS 2023 also introduces a one-third threshold specifically for first-time offenders |
| Bhim Singh v. Union of India (2014) | SC 3-judge bench directed Jurisdictional Magistrates and Sessions Judges to hold weekly sittings in jails for 2 months to identify and release eligible undertrials under Section 436A — a structural remedy for systemic non-implementation |
| Arnesh Kumar v. State of Bihar (2014) | SC laid down guidelines for arrests in offences punishable with up to 7 years imprisonment — police cannot arrest mechanically; must record reasons; magistrate must apply mind before remand |
| NCRB Prison Statistics | Undertrials = 75.8% of prison population; occupancy rate = 131.4% (from NCRB data, as cited in the chapter file) |
| First-time offender (BNSS 479) | Under BNSS 2023, first-time offenders may be considered for bail after serving 1/3 of the maximum sentence (not 1/2) — a new, more lenient threshold |
[Additional] Undertrial Reform — Section 479 BNSS, Bhim Singh, Arnesh Kumar (GS2 — Governance / Criminal Justice):
Section 436A CrPC → Section 479 BNSS — key comparison:
| Feature | Section 436A CrPC (old) | Section 479 BNSS 2023 (new) |
|---|---|---|
| Threshold | Served half the maximum sentence | Served half the maximum sentence (general rule) |
| First-time offender exception | Not present | One-third threshold for first-time offenders |
| Applicability | Not applicable to death penalty offences | Same exclusion |
| Court discretion | Court has discretion (may or may not release) | Same |
Bhim Singh v. Union of India (2014) — structural remedy:
| Parameter | Detail |
|---|---|
| Problem identified | Section 436A (release after serving half sentence) was widely not being applied by courts and jails; eligible undertrials remained imprisoned |
| SC direction | All Jurisdictional Magistrates and Sessions Judges to conduct weekly sittings in each jail for 2 months to identify and release eligible undertrials |
| Impact | Created a systematic review process; district courts had to proactively identify and release eligible undertrials rather than wait for applications |
Arnesh Kumar v. State of Bihar (2014) — arrest limitations:
| Guideline | Detail |
|---|---|
| Scope | Offences punishable with up to 7 years imprisonment (Section 41 CrPC) |
| Police requirement | Must record reasons for arrest in writing; cannot arrest merely because an FIR is registered |
| Magistrate requirement | Must apply mind before authorising remand; must record reasons for extending detention |
| Purpose | Reduce arbitrary arrests; protect personal liberty under Article 21 |
| Consequence | Magistrates who mechanically extend remand without applying mind can be liable |
Law Commission 268th Report (2017) — recommendation for a Bail Act:
- Recommended a standalone Bail Act with:
- Clear statutory criteria for granting/refusing bail (reduce judicial arbitrariness)
- Reduced dependence on sureties (which discriminate against the poor who cannot arrange sureties)
- Codification of SC bail jurisprudence (Arnesh Kumar, Sushila Aggarwal v. State NCT Delhi 2020 on anticipatory bail)
UPSC synthesis: Key exam facts: Section 436A CrPC = undertrial released after serving half of maximum sentence = NOT applicable to death penalty cases; Section 479 BNSS 2023 = reproduces Section 436A + adds one-third threshold for first-time offenders; Bhim Singh (2014) = SC directed weekly jail sittings by Magistrates/Sessions judges to identify eligible undertrials; Arnesh Kumar (2014) = limits arrest for offences punishable up to 7 years = police must record reasons = magistrate must apply mind before remand; undertrials = 75.8% of prison population; occupancy rate = 131.4%; Law Commission 268th Report 2017 = recommended standalone Bail Act. Prelims trap: Section 479 BNSS introduces one-third threshold only for first-time offenders (general rule remains one-half); the Section 436A/479 provision does NOT apply to offences punishable with death penalty (life imprisonment offences ARE covered, only death penalty is excluded); anticipatory bail (Section 482 BNSS) is bail BEFORE arrest — Section 479 bail is for those ALREADY in custody as undertrials — these are legally distinct provisions; Arnesh Kumar (2014) guidelines apply to arrests in offences punishable with up to 7 years (NOT 10 years or all offences).
[Additional] 6b. Model Prison Act 2023 — Structural Innovations and Why Prisons Is a State Subject
The chapter mentions Model Prison Act 2023 but gives no details on its key structural innovations (individual sentence planning, open prisons, technology) or the critical point that it is a model law and prisons is a State List subject.
Key Terms — Model Prison Act 2023:
| Term | Meaning |
|---|---|
| Model Prisons and Correctional Services Act 2023 | A model law issued by Ministry of Home Affairs; advisory, NOT directly enforceable; states must enact their own conformity legislation; prisons is a State List subject (Entry 4, List II, 7th Schedule) |
| Prisons Act 1894 | Colonial-era law that the Model Prison Act replaces — used the word "prisoner" and focused on custody; did not emphasise rehabilitation |
| Individual Sentence Planning (ISP) | Each prisoner gets a personalised rehabilitation plan based on background, skills, and sentence duration — a key innovation in the 2023 Act |
| Open Prison (Open Jail) | System where prisoners with good conduct live in a semi-free environment, often with families; Rajasthan's Sanganer Open Prison is the largest in India |
| State List | Prisons is Entry 4 of the State List (List II, 7th Schedule) — state governments have exclusive power to legislate on prison administration |
[Additional] Model Prison Act 2023 — Provisions and Governance Significance (GS2 — Governance / Criminal Justice):
Why a model law — not a central law: Prisons is a State List subject (Entry 4, List II, 7th Schedule). Parliament cannot directly legislate on prison administration. The Centre can only issue a model law (advisory framework) that states are encouraged to adopt — this is the same approach used for Model Agricultural Produce Market Committee (APMC) Act and the Model Tenancy Act 2021.
Key structural features of the Model Prison Act 2023:
| Feature | Detail |
|---|---|
| Individual Sentence Planning (ISP) | Each prisoner → personalised rehabilitation plan; considers background, education, skills, and sentence duration |
| Security classification | Prisoners classified by security risk: high-security, semi-open, open jails |
| Open Prisons | Provision for open jails — prisoners with good conduct live with families in semi-free conditions; Rajasthan (Sanganer Open Prison) = most advanced model in India |
| Technology in prisons | Video-conferencing for remand hearings (reduces transport and security risks); electronic surveillance; digital prisoner records |
| Grievance redressal | Formal mechanism for prisoners to complain about conditions; Prison Development Board at state level |
| Special provisions | Separate accommodation for women, transgender prisoners; special programs for juveniles |
| Parole, furlough, remission | Streamlined to incentivise good conduct; clearer criteria |
| Legal aid | Mandatory access to legal aid for undertrials from day of admission |
Replaces the Prisons Act 1894:
| Prisons Act 1894 (colonial) | Model Prison Act 2023 |
|---|---|
| Focus on custody and security | Focus on rehabilitation and reformation |
| Used term "prisoner" | Broader rights-based language |
| No classification of prisoners | Security classification system |
| No rehabilitation plan | Individual Sentence Planning |
| No open prison provision | Open prison framework |
Implementation challenge: Since prisons is a State subject, each state must enact its own legislation based on the model. As of May 2026, very few states have enacted full conformity legislation. The Model Act remains largely aspirational.
UPSC synthesis: Key exam facts: Model Prison Act = 2023 = issued by Ministry of Home Affairs = model law (advisory) = NOT directly enforceable; prisons = State List (Entry 4, List II) = states must pass own laws; replaces Prisons Act 1894; key innovations = Individual Sentence Planning + Open Prisons + technology (video-conferencing for remand) + separate accommodation for women/transgender; Rajasthan's Sanganer Open Prison = largest open prison in India. Prelims trap: Model Prison Act 2023 is a model law — it is NOT directly enforceable (states must legislate); prisons is a State List subject (NOT Concurrent List — a common error; if it were Concurrent, Parliament could legislate directly; because it is State List, only a model law is possible); Open prisons are most developed in Rajasthan (not a Central government initiative — it is a state-level implementation); the Model Prison Act replaces the Prisons Act 1894 (NOT the CrPC or BNSS — CrPC/BNSS governs criminal procedure, not prison administration).
Exam Strategy
Prelims traps:
- Article 20(2) is double jeopardy (not tried twice for same offence); Article 20(3) is self-incrimination — keep these distinct
- NALSA's Patron-in-Chief is the Chief Justice of India (not the Law Minister or Attorney General)
- Anticipatory bail is under Section 438 CrPC → now Section 482 BNSS 2023; granted by Sessions Court or High Court (not magistrate)
- CrPC has been replaced by BNSS 2023 — use updated references in Mains answers
- FIR is mandatory for cognizable offences; non-cognizable offences require magistrate's permission to investigate
- Undertrials form ~76% of prison population — a persistent GS2 governance failure, not merely a criminal justice statistic
Mains angles:
- Criminal justice reform — evaluate the three new criminal laws (BNS, BNSS, BSA) as substantive reform vs. repackaging
- Prison overcrowding and undertrial detention as Article 21 violations — what structural reforms are needed?
- Role of NALSA in ensuring access to justice for marginalised groups
