Under the Indian Constitution, the distribution of legislative powers is governed by Article 246 and the Seventh Schedule. Parliament has exclusive power to legislate on subjects enumerated in the Union List (List I), which includes matters of national importance like defense and foreign affairs [2]. Additionally, Article 246(2) grants Parliament the power to legislate on subjects in the Concurrent List (List III), where both the Union and State Legislatures have authority [3]. While the State Legislature normally has exclusive power over the State List (List II), Parliament's regular legislative domain encompasses both the Union and Concurrent Lists [5]. In the event of a conflict between a Central law and a State law regarding a Concurrent subject, the Central law generally prevails [5]. Therefore, Parliament normally legislates on subjects in both the Union and Concurrent Lists.
