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

Key Term

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 Connect

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

Key Term

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 Connect

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

Explainer

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

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
