The document defines a First Information Report (FIR) and outlines related procedures. An FIR is the earliest information about a cognizable crime recorded by the police. It can be filed by any person with knowledge of the crime. The FIR must be registered by the police at the local police station where the crime occurred. Guidelines provide that FIR registration is mandatory for cognizable offenses, while preliminary inquiries may be conducted for other cases to determine jurisdiction. Reasons must be provided if there is any delay or refusal to register an FIR. Online filing of FIRs is also available in some states for cognizable offenses.
