Hugo Black,
United States v. Chicago Heights Trucking Company…
“ So far as pertinent here, the tariffs before us propose rates for transportation of commodities in less than truck-load lots. All commodities (with exceptions not here material) are as a group given the same special rate. In general, respondents' other tariffs provide rates which vary for different types of commodities. Accordingly, if the suspended rates were in effect, transportation of the same commodity over the same haul might cost a forwarder less than other shippers. ”
