The Criminal Justice System (CJS) is a concept and a network of government agencies responsible for maintaining social control, preventing crime, and penalizing those who break the law. Its primary aim is to ensure justice, uphold the rule of law, and provide relief to victims. The modern Indian CJS is rooted in the colonial era, established by the British administration to create a uniform legal framework across the country. This system was built upon three main pillars: the Indian Penal Code (IPC), 1860, which defined offenses and punishments; the Code of Criminal Procedure (CrPC), 1973, which outlined the investigation and trial process; and the Indian Evidence Act (IEA), 1872, which governed the admissibility of evidence.
The CJS works through four interconnected components: the Police (Law Enforcement), the Prosecution, the Courts (Judiciary), and the Correctional System (Prisons). The Police register the complaint, investigate the crime, and file a charge sheet. The Prosecution, representing the State, presents the case in court to prove the accused's guilt beyond a reasonable doubt. The Judiciary, which includes the Supreme Court, High Courts, and subordinate courts, ensures a fair trial and interprets the law. The Correctional System manages undertrials and convicted persons, focusing on punishment and rehabilitation. The system follows an adversarial model, where the accused is presumed innocent until proven guilty.
The CJS has undergone a massive recent change with the replacement of the three principal colonial-era laws. The IPC, 1860, has been replaced by the Bharatiya Nyaya Sanhita (BNS), 2023. The CrPC, 1973, has been superseded by the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023. The IEA, 1872, has been substituted by the Bharatiya Sakshya Adhiniyam (BSA), 2023. These new codes, which came into effect on July 1, 2024, aim to modernize the legal landscape by introducing new offenses like organized crime and terrorist acts, integrating technology, and adding community service as a punishment for petty offenses. For instance, the offense of Sedition under IPC Section 124A has been replaced by a provision in the BNS, 2023, which deals with acts endangering the sovereignty, unity, and integrity of India. While the colonial-era laws were repealed, the core structure of the CJS, including the roles of the Police, Courts, and Prisons, remains the same.
