What is the significance of the Union List in this context?
The significance of the Union List in this context is that it enumerates various subjects and matters over which Parliament has exclusive power to make laws. This includes, but is not limited to, the power to establish additional courts for better administration of laws made by Parliament or any existing laws with respect to a matter enumerated in the Union List. Additionally, the power to make any law with respect to any matter not enumerated in the Concurrent List or State List is also derived from the Union List. This means that Parliament can legislate on subjects not covered by the other two lists, as long as they are related to a matter listed in the Union List.
