Explanation:

Legislative powers of the Parliament :

• The distribution of legislative powers between the Centre and the states is to be maintained in normal times. But, in abnormal times, the distribution is either modi fi ed or suspended. In other words, the Constitution empowers the Parliament to make laws on any matter enumerated in the State List Without consent of any State under the following five extraordinary circumstances:
• When Rajya Sabha Passes a Resolution: If the Rajya Sabha declares that it is necessary in the national interest that Parliament should make laws on a matter in the State List, then the Parliament becomes competent to make laws on that matter.
• During a National Emergency: The Parliament acquires the power to legislate with respect to matters in the State List, while a proclamation of national emergency is in operation.
• When States Make a Request: When the legislatures of two or more states pass resolutions requesting the Parliament to enact laws on a matter in the State List, then the Parliament can make laws for regulating that matter. A law so enacted applies only to those states which have passed the resolutions. However, any other state may adopt it afterwards by passing a resolution to that effect in its legislature. Such a law can be amended or repealed only by the Parliament and not by the legislatures of the concerned states.
