Hugo Black,
State Of North Carolina v. United States Davis…
“ The four states attack the finding of discrimination against interstate commerce which finding is essential to the validity of the present order to maintain intrastate fares at the level of interstate fares, on the ground that there is neither finding nor evidence that the intrastate rates are not producing a proper proportion of the carriers' needed revenue. This Court sustains the attack as sufficient to invalidate the Commission order. ”
