David Josiah Brewer,
Patterson v. Eudora — Opinion of the Court
“ Any restriction upon it deriving validity from an external source would imply a diminution of its sovereignty to the extent of the restriction, and an investment of that sovereignty to the same extent in that power which could impose such restriction. All exceptions, therefore, to the full and complete power of a nation within its own territories must be traced up to the consent of the nation itself. ”
