Quick Answer
Criminal law is the branch of law that defines acts harmful to society and prescribes state-imposed punishment for those who commit them. Unlike civil law, which resolves disputes between private parties, criminal law treats offenses as wrongs against the public at large. In India, the substantive law is codified in the Bharatiya Nyaya Sanhita, 2023 (replacing the IPC 1860), while procedure is governed by the Bharatiya Nagarik Suraksha Sanhita, 2023 (replacing the CrPC 1973). In the US, criminal law operates through both the Model Penal Code (a persuasive draft adopted in varying degrees by states) and individual state and federal statutes.
