George Shiras, Jr.,
Lake Shore Railway Company v. Ohio ex rel…
“ By refraining from action, congress, in effect, adopts as its own regulations those which the common law, or the civil law where that prevails, has provided for the government of each business, and those which the states, in the regulation of their domestic concerns, have established affecting commerce, but not regulating it, within the meaning of the constitution. In fact, congressional legislation is only necessary to cure defects in existing laws, as they are discovered, and to adapt such laws to new developments of trade. ”
