When a conflict arises between a federal (Parliament) law and a state law on the same subject, the federal law generally prevails due to the Supremacy Clause of many constitutions (like the U.S. or Indian), meaning the state law becomes void or invalid to the extent of the inconsistency, though the state law may stand if it receives Presidential assent and Parliament hasn't legislated later, or if Parliament allows state laws. This principle, known as preemption, ensures national laws are supreme, especially on subjects listed in a Concurrent List where both levels can legislate.
