Constitutional
Summary
Neither Parliament nor any State Legislature can pass a law that gives one State an advantage over another, or that treats one State differently from another, when the law is based on trade and commerce matters listed in the Seventh Schedule. However, Parliament can make such a law if the law itself states that it is needed to handle a shortage of goods in any part of India.
