A few persons in urban areas questioned prohibition, saying how come the state was concerned what a citizen eats or drinks, Kumar said at a function in Saharsa.
But, consumption of liquor cannot be the fundamental right of a citizen.
"Article 47 of the Constitution gives direction that the state should protect health and nutrition of its citizen and strive to achieve total prohibition," he said, to justify his government's April 5 decision to put a complete ban on alcohol, country, spiced and Indian Made Foreign Liquor (IMFL).
"Liquor does not come under the purview of Article 19 of the Constitution providing fundamental right to citizens," he said.
