Legal Commentary & Landmark Judgments: Section 175
Section 175 of the Bharatiya Nagarik Suraksha Sanhita, 2023 defines the police officer's plenary power to investigate cognizable offences and the Judicial Magistrate's supervisory power under Section 156(3) CrPC equivalent.
Under sub-section (4), application under sub-section (3) must be supported by an affidavit explaining prior compliance with Section 173(1) and 173(4).
Section 175 is the primary courtroom remedy for aggrieved citizens when police refuse to register an FIR. Following the statutory codification of Priyanka Srivastava in Section 175(4), applications must include verified affidavits and postal receipts of complaints sent to the Superintendent of Police.
