The Supreme Court held that the Madhya Pradesh Special Police Establishment of the Lokayukt Organisation — which investigates corruption under the Prevention of Corruption Act and IPC sections 409, 420 and Chapter XVIII — is not an 'intelligence and security' organisation within Section 24(4) of the Right to Information Act, 2005, and struck down the State notification exempting it. It also held that a court may test the vires of subordinate legislation suo motu once the issue squarely arises and the State is heard.
