In view of various counter claims regarding registration or non-registration, what is necessary is only that the information given to the police must disclose the commission of a cognizable offence. In such a situation, registration of a FIR is mandatory. However, if no cognizable offence is made out in the information given, then the FIR need not be registered immediately and perhaps the police can conduct a sort of preliminary verification or inquiry for the limited purpose of ascertaining as to whether a cognizable offence has been committed. But, if the information given clearly mentions the commission of a cognizable offence, there is no other option but to register a FIR forthwith. Other considerations are not relevant at the stage of registration of FIR, such as, whether the information is falsely given, whether the information is genuine, whether the information is credible etc. These are the issues that have to be verified during the investigation of the FIR. At the stage of registration of a FIR, what is to be seen is merely whether the information given ex facie discloses the commission of a cognizable offence. If, after investigation, the information given is found to be false, there is always an option to prosecute the complainant for filing a false FIR.
