My wife filed a false complaint under Section 377 against me, and an FIR was registered. However, the medical report clearly states otherwise. What is the investigating officer supposed to do? How long will the process take? Can this FIR be dismissed based on the medical report? Or can the investigating officer add further charges and submit a chargesheet?

The investigating officer is obligated to thoroughly investigate the case, considering the medical report and any other evidence. Based on the findings, the FIR may be dismissed if the medical report conclusively proves the allegations false. The officer can also add further charges if evidence suggests other offenses. The duration of the process varies based on the complexity of the case.
