The next comment was, there should be no reference to the power in relation to trade and commerce. It was advisedly put in for the reason that there might be very many powers which may be exercised by the different States in regard to supply of goods, the internal or indigenous industry, which may trench upon trade and commerce but which may not bear directly upon trade and commerce. It is not the intention to interfere with these powers of the Provinces or States. Therefore, the main article itself provides that by virtue of any power vested in them in regard to trade and commerce, neither Parliament nor the legislature shall enact any discriminatory law.
