How does List I relate to public order and use of armed forces?
List I does not explicitly mention public order or the use of armed forces. However, it includes "The use of any naval, military or air force or any other armed force of the Union or of any other force subject to the control of the Union or of any contingent or unit thereof in aid of the civil power" under Entry 2A. This implies that the central government has the power to deploy armed forces for maintaining public order when required.
