Stanley Matthews, Bowman v. Chicago N W Railway Company…
“ It is not one of those local regulations designed to aid and facilitate commerce; it is not an inspection law to secure the due quality and measure of a commodity; it is not a law to regulate or restrict the sale of an article deemed injurious to the health and morals of the community; it is not a regulation confined to the purely internal and domestic commerce of the state; it is not a restriction which only operates upon property after it has become mingled with and forms part of the mass of the property within the state. ”
