Charles Evans Hughes, Louisville Nashville Railroad Company v…
“ The lawful rate is that which the carrier must exact and that which the shipper must pay. The shipper's knowledge of the lawful rate is conclusively presumed, and the carrier may not be required to surrender the goods carried upon the payment of the rate paid, if that was less than the lawful rate, until the full legal rate has been paid.' It was 'the purpose of the act to have but one rate, open to all alike, and from which there could be no departure.' Boston & M. R. Co. ”
