The correct option is D (all the above).
– The power to enact laws for preventive detention is covered in the Seventh Schedule of the Constitution.
– Union List (List I): Entry 9 specifically lists “Preventive detention for reasons connected with Defence, Foreign Affairs, or the Security of India; persons subjected to such detention”. Parliament has exclusive power to legislate on items in the Union List.
– Concurrent List (List III): Entry 3 lists “Preventive detention for reasons connected with the security of a State, the maintenance of public order, or the maintenance of supplies and services essential to the community; persons subjected to such detention; regulation of the place and conditions of detention of such persons”. Both Parliament and state legislatures can legislate on items in the Concurrent List.
– Since Defence, Foreign Affairs, and Security of India are explicitly mentioned in Entry 9 of the Union List, Parliament is entitled to enact a law of preventive detention for reasons connected with all these three areas.
Preventive detention is a contentious issue in India’s legal framework, allowing for detention of individuals without trial based on suspicion that they may commit a future crime, for reasons specified in the Lists. Safeguards against misuse are provided in Article 22 of the Constitution.
