What is Indian Constitution?

Constitution is the foundational law of a country which ordains the fundamental principles on which the government (or the governance) of that country is based. It lays down the framework and principal functions of various organs of the government as well as the modalities of interaction between the government and its citizens. With the exception of the United Kingdom (U.K.), almost all democratic countries possess a written constitution. India also possesses an elaborate written constitution which was enacted by a constituent assembly specifically set up for the purpose.
