constitutes a cognizable offence. The purpose of registering an FIR is to set the machinery of criminal investigation into motion, which culminates with filing of the police report in terms of Section 173(2) of the Code. It will, thus, be appropriate to follow the settled principle that there cannot be two FIRs registered for the same offence. However, where the incident is separate; offences are similar or different, or even where the subsequent crime is of such magnitude that it does not fall within the ambit and scope of the FIR recorded first, then a second FIR could be registered. The most important aspect is to examine the inbuilt safeguards provided by the legislature in the very language of Section 154 of the Code. These safeguards can be safely deduced from the principle akin to double jeopardy, rule of fair investigation and further to prevent abuse of power by the investigating authority of the police. Therefore, second FIR for the same incident cannot be registered. Of course, the investigating agency has no determinative right. It is only a right to investigate in accordance with the provisions of the Code. The filing of report upon completion of investigation, either for cancellation or alleging commission of an offence, is a matter which once filed before the court of competent jurisdiction attains a kind of finality as far as police is concerned, may be in a given case, subject to the right of further investigation but wherever the investigation has been completed and a person is found to be prima facie guilty of committing an offence or otherwise, re-examination by the investigating agency on its own should not be permitted merely by registering another FIR with regard to the same offence. If such protection is not given to a suspect, then possibility of abuse of investigating powers by the police cannot be ruled out. It is with this intention in mind that such interpretation should be given to Section 154 of the Code, as it would not only further the object of law but even that of just and fair investigation. More so, in the backdrop of the settled canons of criminal jurisprudence, reinvestigation or de novo investigation is beyond the competence of not only
