When investigation can be monitored by the Court?

As held by the Supreme Court in a catena of judgments that there is a well-defined and demarcated function in the field of investigation and its subsequent adjudication. It is not the function of the court to monitor the investigation process so long as the investigation does not violate any provision of law. It must be left to the discretion of the investigating agency to decide the course of investigation. If the court is to interfere in each and every stage of the investigation and the interrogation of the accused, it would affect the normal course of investigation. It must be left to the investigating agency to proceed in its own manner in interrogation of the accused, nature of questions put to him and the manner of interrogation of the accused.

 It is one thing to say that if the power of investigation has been exercised by an investigating officer mala fide or non-compliance of the provisions of the Criminal Procedure Code in the conduct of the investigation, it is open to the court to quash the proceedings where there is a clear case of abuse of power.
