RMDC V. UNION OF INDIA AIR 1957 SC 628
DOCTRINE OF SEVERABILITY
This Hon'ble court explained the doctrine as follows "When a legislature whose authority is subject to limitations aforesaid enacts a law which is wholly in excess of its powers, it is entirely void and must be completely ignored. But when the legislation falls in part within the area allotted to it and in part outside it, it is undoubtedly void as to the latter; but does it on that become necessarily void in its entirety? The answer to this question must depend on whether what is valid could be separated from what is invalid, and that is a question which has to be decided by the Court on a consideration of the provisions of the act.”
