THE STATE OF MADHYA PRADESH vs MUBARAK ALI

The Supreme Court held that Section 5A of the Prevention of Corruption Act, 1947 mandates that no police officer below the rank of Deputy Superintendent can investigate certain offenses without a Magistrate's order that discloses relevant material and reasons. The Court emphasized that the Magistrate must exercise discretion based on available material and cannot delegate this authority to a police officer. The High Court's order to allow a subordinate officer to investigate was set aside, reinforcing the need for strict compliance with statutory safeguards to prevent frivolous prosecutions.
