"156. (3) Any Magistrate empowered under Section 190 may order such an investigation as abovementioned."
Powers of magistrate - "2. This Court has held in Sakiri Vasu v. State of U.P., that if a person has a grievance that his FIR has not been registered by the police, or having been registered, proper investigation is not being done, then the remedy of the aggrieved person is not to go to the High Court under Article 226 of the Constitution of India, but to approach the Magistrate concerned under Section 156(3) CrPC. If such an application under Section 156(3) CrPC is made and the Magistrate is, prima facie, satisfied, he can direct the FIR to be registered, or if it has already been registered, he can direct proper investigation to be done which includes in his discretion, if he deems it necessary, recommending change of the investigating officer, so that a proper investigation is done in the matter. We have said this in Sakiri Vasu case because what we have found in this country is that the High Courts have been flooded with writ petitions praying for registration of the first information report or praying for a proper investigation." Sudhir Bhaskarrao Tambe v. Hemant Yashwant Dhage and Others, (2016) 6 SCC 277 referred in 2020 SCeJ 352
Powers of Magistrate - ""11. The clear position therefore is that any Judicial Magistrate, before taking cognizance of the offence, can order investigation under Section 156(3) of the Code. If he does so, he is not to examine the complainant on oath because he was not taking cognizance of any offence therein. For the purpose of enabling the police to start investigation it is open to the Magistrate to direct the police to register an FIR. There is nothing illegal in doing so. After all registration of an FIR involves only the process of entering the substance of the information relating to the commission of the cognizable offence in a book kept by the officer in charge of the police station as indicated in Section 154 of the Code. Even if a Magistrate does not say in so many words while directing investigation under Section 156(3) of the Code that an FIR should be registered, it is the duty of the officer in charge of the police station to register the FIR regarding the cognizable offence disclosed by the complainant because that police officer could take further steps contemplated in Chapter XII of the Code only thereafter." Mohd. Yousuf vs. Afaq Jahan, quoted in Sakiri Vasu v. State Of Uttar Pradesh And Others, (2008) 2 SCC 409 referred in 2020 SCeJ 352
Powers of Magistrate - "Even if an FIR has
been registered and even if the police has made the investigation, or is actually making the investigation, which the aggrieved person feels is not proper, such a person can approach the
Magistrate under Section 156(3) CrPC, and if the Magistrate is satisfied he can order a proper investigation and take other suitable steps and pass such order(s) as he thinks necessary for
ensuring a proper investigation. All these powers a Magistrate enjoys under Section 156(3) CrPC. " Sakiri Vasu v. State Of Uttar Pradesh And Others, (2008) 2 SCC
