How does this power relate to Parliament's role in election-related matters?
This power relates to Parliament's role in election-related matters by allowing the Legislature of a State to make provisions with respect to elections to their House or either House, including electoral roll preparation and other necessary measures for the proper constitution of the State legislatures. However, this power is subject to the provisions of the Constitution, and Parliament may make its own provisions where it sees fit. Additionally, courts are barred from interfering in electoral matters, with election validity challenges only allowed through election petitions presented to specified authorities under laws made by the appropriate Legislature.
