The criminal justice system involves reporting offenses to the police, who may register an FIR and begin investigating. For cognizable offenses, the police can make arrests without a warrant. If the police refuse to register an FIR, the complainant can approach higher authorities or the court. Arrested individuals must be informed of the reasons for arrest and produced before a magistrate within 24 hours. The criminal process also involves bail procedures, investigation, filing charges, and trial, which can result in conviction or acquittal. The key laws governing the criminal justice system are the Code of Criminal Procedure, Indian Penal Code, and Indian Evidence Act.
