William O. Douglas,
Rice v. Santa Fe Elevator Corporation…
“ For instance, has Congress really expressed with reasonable clarity its purpose to forbid to the States the fixing of warehouse rates and thus deprive the States of a long-standing regulatory power which the United States chose not to assume? Is it not more consistent with a proper regard for the interplay of State and national interests to assume that Congress was imposing a minimum of regulation for those who accepted federal licenses rather than to assume that by inferential sterilization of State laws Congress meant to make its optional and restricted requirements the maximum? ”
