I hereby reproduce para 9 from the judgment of Supreme Court in the case of Gangadhar Janardan Mhatre Vs. State of Maharashtra and Ors. (2005 (2) LJSOFT (SC) 46)
"When a report forwarded by the police to the Magistrate under Section 173(2)(i) is placed before him several situations arise. The report may conclude that an offence appears to have been committed by a particular person or persons and in such a case, the Magistrate may either (1) accept the report and take cognizance of the offence and issue process, or (2) may disagree with the report and drop the proceeding, or (3) may direct further investigation under Section 156(3) and require the police to make a further report. The report may on the other hand state that according to the police, no offence appears to have been committed. When such a report is placed before the Magistrate he has again option of adopting one of the three courses open i.e., (1) he may accept the report and drop the proceeding; or (2) he may disagree with the report and take the view that there is sufficient ground for further proceeding, take cognizance of the offence and issue process; or (3) he may direct further investigation to be made by the police under Section 156(3). The position is, therefore, now well-settled that upon receipt of a police report under Section 173(2) a Magistrate is entitled to take cognizance of an offence under Section 190(1)(b) of the Code even if the police report is to be effect that no case is made out against the accused. The Magistrate can take into account the statements of the witnesses examined by the police during the investigation and take cognizance of the offence complained of and order the issue of process to the accused."
