David Josiah Brewer,
Austin v. Tennessee/Dissent Brewer…
“ The power of Congress to regulate commerce between the states being, as we have seen, supreme, its failure to impose any restrictions or regulations is to be taken as a declaration that, in its judgment, such commerce shall be free. There is no necessity of an affirmative declaration on its part, for, as it alone has power to restrict or prescribe regulations, its failure to do so leaves the commerce unburdened. ”
