State the Doctrine of Constitutional Supremacy

Under this doctrine, if a law or contract VIOLATES ANY NORM OF THE CONSTITUTION, that law or contract, whether promulgated by the legislative or by the executive branch or entered into by private persons for private purposes, is NULL AND VOID and without any force and effect. Since the Constitution is the fundamental, paramount and supreme law of the nation, it is deemed written in every statute and contract. (Manila Prince Hotel v GSIS, G.R. No. 122156, February 3, 1997)
