Can you explain the concept of "Residuary powers of legislation" mentioned in this text?
The concept of "Residuary powers of legislation" refers to the authority granted to Parliament by Article 248(1) (subject to Article 246A), allowing it to make any law with respect to any matter not enumerated in the Concurrent List or State List. This power extends to enacting laws on taxes that are not mentioned in either of those Lists, as stated in Article 248(2). Essentially, this provision grants Parliament the ability to legislate on subjects or matters that fall outside the jurisdiction of the state governments or concurrent powers of both levels of government.
