If such an application under Section 156(3) Cr.P.C. 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. Thus, the law laid down by Hon'ble Supreme Court is that after registration of the First Information Report if proper investigation is not being done by the investigating officer, then informant may approach the magistrate concerned
