Question 1

A nationwide consensus emerges among states regarding the need for uniform legislation on 'Public Order' (a State List subject) to effectively combat a new form of organized crime that transcends state boundaries. Considering the principles of cooperative federalism, which constitutional mechanism would be most appropriate for the Union Parliament to enact such a law, ensuring state concurrence and applicability?

Accepted Answer

C. Two or more State Legislatures passing resolutions requesting Parliament to legislate on 'Public Order' under Article 252. — Article 252 of the Indian Constitution provides a mechanism where Parliament can legislate on a State List subject if two or more state legislatures pass resolutions requesting it. This approach is highly collaborative and respects federal principles as it relies on the explicit consent of states. Other options involve emergency powers (less collaborative), temporary measures (Article 249), or administrative directives (Article 256, not legislative power).

Answer

A. Parliament exercising its power to legislate on any subject during a Proclamation of National Emergency under Article 352.

Answer

B. The Rajya Sabha declaring 'Public Order' as a matter of national interest by a resolution under Article 249.
