If the State Government 's impugned notification is assumed to be a law enacted by that State 's Legislature on Entry 26 of List II, since the Act of Parliament passed on Entry 33 of List III and the Fertilizer (Control) Order, 1957 passed under that Act were already in force, the assent of the President had to be received in order that the State Government 's notification assumed to be a law enacted by the State 's Legislature may prevail in the State as required by Article 254(2) of the Constitution which reads thus: "Where a law made by the Legislature of a State with respect to one of the matters enumerated in the Concurrent 380 List contains any provision repugnant to the provisions of an earlier law made by Parliament or an existing law with respect to that matter, then, the law, so made by the Legislature of such State shall, if it has been reserved for the consideration of the President and has received his assent, prevail in that State: Provided that nothing in this clause shall prevent Parliament from enacting at any time any law with respect to the same matter including a law adding to, amending, varying or repealing the law so made by the Legislature of the State.
