Introduction
India’s criminal justice system, rooted in colonial-era legislation such as the Indian Penal Code of 1860 and the Code of Criminal Procedure of 1973, has undergone significant transformation through judicial interpretation and legislative reform. The Supreme Court and various High Courts have been at the forefront of ensuring that the criminal justice system upholds the constitutional guarantees of fairness, due process, and human dignity. At the same time, Parliament has enacted a new suite of criminal laws under the Bharatiya Nyaya Sanhita (BNS), Bharatiya Nagarik Suraksha Sanhita (BNSS), and Bharatiya Sakshya Adhiniyam (BSA) to replace the colonial statutes.
Despite these reforms, the criminal justice system continues to grapple with issues of prison overcrowding, prolonged undertrial detention, custodial violence, and inadequate legal aid. This article examines some of the landmark judicial pronouncements and legislative developments that have shaped criminal justice in India.
The Right Against Self-Incrimination: Nandini Satpathy v. P.L. Dani (1978)
Article 20(3) of the Indian Constitution guarantees that no person accused of any offence shall be compelled to be a witness against himself. The Supreme Court in Nandini Satpathy v. P.L. Dani gave a broad interpretation to this fundamental right, holding that it applies not merely to accused persons during trial but also to persons called for interrogation by the police. The Court held that the right to remain silent extends to all stages of the criminal process.
This judgment was further developed in Selvi v. State of Karnataka (2010), where the Supreme Court unanimously held that narcoanalysis, polygraph, and brain-mapping tests conducted without the consent of the accused violate Article 20(3) and Article 21. The Court affirmed that the state cannot compel an accused to contribute evidence that may be used against them, even through scientific investigation techniques.
Bail Jurisprudence: Satender Kumar Antil v. CBI (2022)
The Supreme Court in Satender Kumar Antil v. CBI delivered a comprehensive judgment on bail jurisprudence in India, emphasizing that bail is the rule and jail is the exception. The Court expressed grave concern over the large number of undertrials languishing in prisons and issued detailed guidelines for the grant of bail, directing courts to consider bail applications expeditiously and to adopt a liberal approach where the accused is unlikely to flee or tamper with evidence.
The judgment has had significant practical implications for the millions of undertrials who constitute nearly 70% of India’s prison population. The Court’s emphasis on proportionality and the presumption of innocence has strengthened the constitutional foundation of bail law and provided clearer guidance to trial courts and High Courts across the country.
Custodial Violence and Torture
The Supreme Court in D.K. Basu v. State of West Bengal (1997) laid down landmark guidelines to prevent custodial violence and protect persons in police custody. The guidelines, which have since been given statutory backing through the Code of Criminal Procedure, require police officers making arrests to carry identification, prepare a memo of arrest, inform family members, and allow the arrested person to consult a lawyer. Violation of these guidelines was held to render the concerned official liable for contempt of court in addition to other penal and administrative consequences.
Despite these protections, custodial deaths and torture continue to be a grave concern in India. The Supreme Court in subsequent decisions has reiterated that torture by law enforcement authorities is a gross violation of human rights and the right to dignity under Article 21, and has called for the swift prosecution of erring officials.
Sedition Law: S.G. Vombatkere v. Union of India (2022)
In a significant development, the Supreme Court in S.G. Vombatkere v. Union of India stayed the operation of Section 124A of the Indian Penal Code (sedition) and directed the Central Government to reconsider the provision in light of its colonial origins and its potential for misuse to suppress legitimate dissent. The Court noted that the sedition law had been widely criticized for being used against journalists, activists, and political opponents in a manner inconsistent with the constitutional guarantee of freedom of speech and expression.
This case highlighted the broader issue of the weaponization of criminal law against critics of the government and the urgent need for reform of laws that have a chilling effect on free speech and political expression in a democratic society.
Death Penalty and Sentencing: Bachan Singh v. State of Punjab (1980)
The Supreme Court in Bachan Singh v. State of Punjab upheld the constitutional validity of the death penalty but held that it should be imposed only in the rarest of rare cases where the alternative of life imprisonment is unquestionably foreclosed. The judgment established a two-stage sentencing process that requires courts to weigh aggravating and mitigating circumstances before imposing the death penalty, shifting the approach from mandatory capital punishment to guided judicial discretion.
Subsequent judgments have further refined the rarest of rare doctrine and have recognized that the personal circumstances of the accused, including mental health, social background, and the possibility of reformation, must be considered in sentencing. The Supreme Court has also taken cognizance of the arbitrary and discriminatory application of the death penalty and has called for a comprehensive review of capital punishment in India.
The New Criminal Laws
In 2023, Parliament replaced the colonial-era criminal laws with three new statutes — the Bharatiya Nyaya Sanhita (BNS), the Bharatiya Nagarik Suraksha Sanhita (BNSS), and the Bharatiya Sakshya Adhiniyam (BSA). These laws came into force on July 1, 2024, and introduced several reforms including timelines for investigation and trial, increased use of technology in court proceedings, and a revised framework for bail and sentencing. However, critics have noted that the new laws retain many problematic provisions from the colonial codes and have introduced new concerns regarding civil liberties.
Conclusion
Criminal justice reform in India is an ongoing and evolving process that requires sustained engagement from the judiciary, the legislature, the executive, and civil society. While landmark judicial decisions have significantly expanded the procedural and substantive protections available to accused persons and undertrials, the translation of these rights into practice remains a challenge. A truly reformed criminal justice system must be one that is fair, efficient, humane, and accessible to all citizens regardless of their socioeconomic status or identity.
