Can you explain how "Article 248(2)" impacts the power of Parliament to make laws concerning taxes not mentioned in either the Concurrent List or State List?
Article 248(2) grants Parliament the exclusive power to make any law with respect to any matter not enumerated in the Concurrent List or State List. This includes the power to impose a tax not mentioned in either of those lists. In other words, if a tax is not specifically mentioned in the Concurrent or State Lists, then it falls under Parliament's jurisdiction and they have the authority to create legislation related to that tax.
