Wiley Blount Rutledge, Robertson v. California (328 U.S. 440…
“ Not the mere fact or form of licensing, but what the license stands for by way of regulation is important. [27] So also, it is not simply the fact of prohibition, but what is forbidden and for the protection of what interest, that is determinative. For the commerce clause is not a guaranty of the right to import into a state whatever one may please, absent a prohibition by Congress, regardless of the effects of the importation upon the local community. That is true whether what is brought in consists of diseased cattle [28] or fraudulent or unsound insurance. ”
