1. The Magistrate has no jurisdiction to order inquiry against the Investing Officer even if there is gross negligence in discharging its duties.

2 . If there is lack of proper investigation you can file writ petition against police inaction.

3. You can also lodge complaint with the higher authority of the Police to transfer of investigation from the present IO to the another one. 

Yes a case can be filed against the IO. But an fir has to be registered with the concerned police station and if the police refuses to register the case then file a complaint against the person before a magistrate under s 156 3 of crpc.

It can order an enquiry only if it has been proved before ehim that such illegalities have been committed by the IO.

Hello,

No the same can only be done by HC under section 482.

Regards

Yes a magistrate has power to initiate the said inquiry as aforesaid

Section 91 cr.p.c.:

Summons to produce document or other thing (1) Whenever any Court or any officer in charge of a police station considers that the production of any document or other thing is necessary or desirable for the purposes of any investigation, inquiry, trial or other proceeding under this Code by or before such Court or officer, such Court may issue a summons, or such officer a written order, to the person in whose possession or power such document or thing is believed to be, requiring him to attend and produce it, or to produce it, at the time and place stated in the summons or order.

action of the Magistrate in issuing summons under Section 91 Cr.P.C cannot be faulted.

The next line of inquiry is, whether the penal provisions for which cognizance has been taken would apply to the facts of this case. For the sake of convenience, Sections 174, 175 and 176 of the IPC.

M.P.No.1 of 2015

Where is the complaint against the IO has been filed in court or senior Police officer.????

If the complainant was been filed in the court then yes CJM or ACJM can order Judicial Inquiry against IO even if the investigation of case is pending. 

1. As per the information mentioned in the present query, makes it clear that you wish to have directions issued to the investigation team (a new one) to investigate about the misconduct of the existing officers.
2. Yes, there is not doubt that these can be done by the court of law, but I have doubt that lower can order for the same.
3. You should file a Writ petition of Mandamus in nature as per article 226 of our Constitution read with section 482 before the Hon’ble High Court seeking immediate intervention of the court.

Yes, u/s 340 CrpC but after trail. While matter is under investigation than can file complaint for giving false information, with intent to cause public servant to use his lawful power to the injury of another person
