Constitution of India –Fundamental law of Land

The Constitution operates as a fundamental law. The governmental organs owe their origin to the constitution and derive their authority from, and discharge their responsibilities within the framework of the constitution. The Union Parliament and the State Legislature are not sovereign. The validity of a law, whether Union or State, is judged with reference to their respective jurisdictions as defined in the constitution. The Judiciary has power to declare a law unconstitutional, if the law is found to have contravened any provision of the Constitution.
