Under BNSS section 175(1), an officer in charge of a police station may investigate a cognizable case…

Section 175(1) gives the station officer authority to investigate the qualifying cognizable case "Without obtaining a Magistrate's order", so "Only after obtaining a Magistrate's order", "Only after obtaining both a Magistrate's order and a superior officer's order" and "Only after obtaining the accused's written consent" add conditions the section does not impose. The local-jurisdiction condition remains, and the proviso permits the Superintendent of Police, considering the offence's nature and gravity, to require investigation by a Deputy Superintendent of Police.
