William Howard Taft,
Western v. Georgia Public Service Commission…
“ It requires a consideration by experts of the benefit of the use of such a siding as compared with that of other sidings in connection with the rates in interstate commerce to determine whether there is undue discrimination between shippers. The railroad company is therefore in no position to appeal to the courts on this ground until it has invoked the investigation and decision of the Interstate Commerce Commission upon the concrete facts in a proper manner. ”
