What is the significance of "exclusive power" as mentioned in Article 248(1)?
The significance of "exclusive power" as mentioned in Article 248(1) is that it gives Parliament the authority to make any law with respect to any matter not enumerated in the Concurrent List or State List, including the power to impose a tax not mentioned in either of those lists. This means that when there is no specific provision in either the Concurrent or State Lists for a particular subject or matter, Parliament has the ultimate authority to legislate on it without any interference from state governments.
