Trade and commerce are not things which are decided once for all; they are things that arise and grow from day to day. They may be varied; there may be circumstances and situations when the whole thing will have to be revised. This may arise so far as a particular State is concerned or in respect of more than one State. How pompously did we decide that there shall be “free trade” everywhere. It is not such an easy thing as that and I hope that this is now broadly realized. For instance, we know that the stage of advancement and progress of the various units of the Union varies considerably. Some of them are backward like Assam or Orissa where there are very few industries and very little trade is in the hands, at least of the indigenous population. We may have probably to give them some protection in order that they may rapidly come on par with other units. It may be necessary also from time to time to vary our provisions so far as aid and concessions to industries and other things are concerned. I therefore do not think that is right to bar all discrimination, as it is called (in fact it is not), barring all possibility of help to those who are backward and who are unable to compete with the more advanced, and who therefore, stand in need of assistance. From that point of view, my amendment seeks to give Parliament a blank cheque and leave to it entirely the determination of the policy. with regard to trade and commerce not only of the whole Union or in regard to any particular State or States, but so far as all States and their trade and commerce inter se is concerned. Therefore, I have proposed a very simple provision as has been embodied in my amendment No. 340.
