A written constitution is essentially a basic expression of the ideas and organization of a government that is formally presented in one document. In other words, it is a rule book of a nation, codifying rule of law.Constitution is a legal document having a special legal sanctity, which sets out the framework and the principal functions of the organs of the government of a state, and declares the principles governing the operation of those organs. Like every other Constitution, the Indian Constitution also seeks to establish the fundamental organs of government and administration, lays down their structure, composition, powers and principal functions, defines the inter-relationship of one organ with another, and regulates the relationship between the citizen and the state, more particularly the political relationship. The states have reasserted certain principles of law through written Constitutions.
