The criminal justice system in India is a complex and developing system to maintain public order, prohibit and deter criminal acts, and secure justice. It is built upon several statutes, principles, and a committed judicial structure. The criminal law system in India has heroic historical legal origins, but its development is largely due to British colonial rule, while recent reforms have ushered in a new period of development. The foundation of India's criminal law system was formed during the British Raj. The Indian Penal Code (IPC), 1860, drafted by the First Law Commission of India, stood as the substantive law that defined criminal offences and codified criminal law in India. The other foundation was the Code of Criminal Procedure (CrPC), 1973, which provided the procedural law for investigation, trial, and punishment. The Indian Evidence Act, 1872 governed evidence law in a criminal trial. Recently, however, these colonial laws were replaced with new laws in 2023. This includes the Bharatiya Nyaya Sanhita (BNS), 2023, replacing the IPC, Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, replacing the CrPC, and the Bharatiya Sakshya Adhiniyam, 2023, replacing the Indian Evidence Act. These new laws aim to modernize the criminal justice system, streamline procedures, and better reflect contemporary societal needs, including introducing provisions for crimes like mob lynching and terrorism. The Indian criminal justice system operates on several fundamental principles. Every person is presumed innocent until proven guilty beyond a reasonable doubt. The burden of proof rests on the prosecution, not the accused. A crime requires both a "guilty act" (actus reus) and a "guilty mind" or criminal intent (mens rea). Generally, a person cannot be held criminally liable for an act without a corresponding malicious intent. Punishment should be proportionate to the severity of the crime. This principle ensures that penalties are just and not excessive. The accused has a right to a fair trial, including the right to legal representation and protection against self-incrimination.
