COIMBATORE: The nation's constitution is what prevails and has to prevail and it was the duty of every citizen to see that the constitutional values, norms and nuances remain sacrosanct, said former Chief Justice of India, Dipak Misra on Saturday. He was speaking at the inaugural session of the fourth edition of the Indian Cyber Congress held at a private college in the city. "Question arises that who is sovereign amongst the three wings of the state -- executive, legislative or judiciary. On occasions there you will find there are certain utterances that there is'parliamentary sovereignty'. But the Supreme Court time and again has reiterated that there is'constitutional sovereignty', meaning thereby it's the Constitution that prevails and that has to prevail. It's the duty of every citizen to see that the constitutional values, norms and nuances are remain sacrosanct," said Misra.
