The result of the aforesaid discussion may be summarized in the following propositions: (i) whether the Constitution affirmatively confers power on the legislature to make laws subject wise or negatively prohibits it from infringing any fundamental right, they represent only two aspects of want of legislative power; (ii) the Constitution in express terms makes the power of a legislature to make laws in regard to the entries in the Lists of the Seventh Schedule subject to the other provisions of the Constitution and thereby circum cribes or reduces the said power by the limitations laid down in Part III of the Constitution; (iii) it follows from the premises that a law made in derogation or in excess of that power would be ab initio void wholly or to the extent of the contravention as the case may be ; and (iv) the doctrine of eclipse can be invoked only in the case of a law valid when made, but a shadow is cast on it by supervening constitutional inconsistency or,supervening existing statutory 41 inconsistency; when the shadow is removed, the impugned Act is freed from all blemish or infirmity.
