A constitution is a system of fundamental laws for the governance and administration of a nation. It is supreme, imperious, absolute and unalterable except by the authority from which it emanates. It has been defined as the fundamental and paramount law of the nation. It prescribes the permanent framework of a system of government, assigns to the different departments their respective powers and duties, and establishes certain fixed principles on which government is founded. The fundamental conception in other words is that it is a supreme law to which all other laws must conform and in accordance with which all private rights must be determined and all public authority administered.Under the doctrine of constitutional supremacy, 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. Thus, since the Constitution is the fundamental, paramount and supreme law of the nation, it is deemed written in every statute and contract. (G.R. No. 122156; February 3, 1997)
