Dear Student,
Normally such questions are not entertained on the platform but as of academic interest I am answering the same as follows. Be informed that FIR is itself a small ocean and you will learn only when you face practical’s in courts. Join the office of middle aged advocate who is exclusively practicing on criminal side and if you wish to practice in High Court then join office of advocate practicing on criminal side in High Court.
1.Do police file FIR directly if some person approaches the police station and asks them to file a FIR?
Ans: They are supposed to conduct preliminary investigation.
2.Is it possible that a person approach the police intention to defame someone and write a FIR against him just to make his/her record bad, even if the person has not committed any crime?
Ans: Yes, but if wrong FIR is lodged and if at the end the result is closing of such FIR then the victim will file defamation case against the complainant.
3.Is it possible that police while writing a FIR makes a mistake and write someone else name as an accuse, lets say if police was about to write a FIR against Sanjay Singh and by mistake it writes Sanjay Vyas?
Ans: Yes, and it can be rectified by recording further statement of the complainant. No body is perfect.
4.When a police catches a criminal then whether is it possible that police while registering the FIR, the criminal doesnt tell his name rather he pretends to be someone else? For example if police catches a person Kapil in drink & drive case, takes him to police station and asks name of criminal and he tells the police that his name is Dinesh along with fake ID of Dinesh, although his actual name is Kapil?
Ans: Such criminal has to face trouble in future as police may file another FIR against him.
4.Is it possible that an criminal FIR may have been registered against a person in some other state and he is unaware of the same? For example lets say Kapil resides in Jaipur and a FIR has been registered against kapil in pune and he is unaware of the same, now he applies for police verification(may be for passport or for job purpose) and the local police station of Jaipur gives a clearance certificate saying that no FIR has been registered against kapil in Pune and which might create problem for him in the future?
Ans: No, clearance certificate is enough. All the court like to know about the intention and bonafides from the person. Please understand you should not misguide the experts. You must be direct. Above questions are not asked by any student but some body who is facing such troubles. If you do like this then you will not be believed in future. If you are a law student then judges will give you negative marks and start to reject your bail applications etc even though your cases have merits.You need discussion if you wish particular solution to resolve your issue.
