It deals with commerce and trade and there is a third-word `intercourse’ also. I am coming to it. So far as commerce and trade is concerned I beg to submit that it is not covered by article 13(g). Let us now refer to sub-clause (6) which says–
“(6) Nothing in sub-clause (g) of the said clause shall affect the operation of any existing law, or prevent the State from making any law, imposing in the interests of public order, morality or health, restrictions on the exercise of the right conferred by the said sub-clause and in particular prescribing or empowering any authority to prescribe, the professional or technical qualifications necessary for practising any profession or carrying on any occupation, trade or business.“
