When Your Friend's Food Is a Little too Tasty, You Think of the Right to Freedom of Trade and Commerce

You know what's as delicious as Amul butter but gives me more trouble than my aunt's cooking? When my friend tries to start his own food stall in our local market, only to find out that the Municipal Corporation is charging him exorbitant fees for a license. I quote Section 42 of Article 19(1)(g) of the Constitution: 'No exception is made in favour of any law that is designed to regulate or restrict in any way trade, commerce or intercourse among the States or with foreign countries.' My friend is basically being asked to shut down his stall because the Corporation says it's not following the rules, but I think they're just trying to squeeze some extra bucks out of him.
