Yes, constitution holds an important place in Indian history.
If there is no constitution, then there will be lack of rules and regulations.People will be deprived of their rights and the government will function according to its will.Justice will be denied to the people and a chaotic situation will prevail in the absence of laws because Constitution is the source of laws.In the absence of a Constitution it will be difficult for a country to sustain in the long run and chances for the outbreak of a revolution will occur.
