The Role of Parliament: The Indian Parliament plays an important role in making laws. There are many ways through which this takes place.

(a) The Parliament is the law-making body at the central level. It frames new laws and amends or repeals them, if necessary, on all the 97 subjects of the Union List and all the Residuary subjects which have not found a place in any of the list.

(b) As far as the 47 subjects in the Concurrent List are concerned, both the Parliament and the state legislatures have got the right to make laws. But if any state law comes into conflict with the central law, the central law shall prevail.

(c) It can enact laws on the 66 subjects of State List also if: 

(1) Rajya Sabha passes a resolution with 2/3 majority to the effect. that the particular subject of the State List has come to assume national importance.

(2) Two or more states request the center to pass a law for them on one or more subjects mutually agreed upon by them. 

(3) A state of national emergency is proclaimed by the President. 

(4) The President takes over the administration of a state on the breakdown of the constitutional machinery in that state. Such laws will concern only the states for which they are passed.

(d) The Union Parliament has the sole right to amend the Constitution, although in certain cases these amendments should also be ratified by a majority of the states. The states can, in case, initiate an amendment to the constitution.
