Owen J. Roberts, Ohio v. United States — Opinion of the Court
“ That if a commodity is shipped in large quantities in interstate commerce from certain districts without Ohio to a destination in that state, and if it happens that the commodity also reaches the same destination from wholly different regions whose rates have been built upon a different key rate, the commission cannot abate a discrimination between the first-named group of rates, found to be reasonable, and the intrastate rates, without first finding that the rate from every other region to the same destination in Ohio is reasonable. ”
