Is there any provision that allows both the central and state governments to make laws on certain subjects?
Yes, there is a provision that allows both the central and state governments to make laws on certain subjects. This is mentioned in Article 246(2) of the Indian Constitution, which states that "Parliament, and, subject to clause (1), the Legislature of any State also, have power to make laws with respect to any of the matters enumerated in List III in the Seventh Schedule (in this Constitution referred to as the “Concurrent List”)." This means that certain subjects are included in both the Union List and the State List, allowing both the central and state governments to make laws on these subjects.
