Hugo Black,
Lloyd Fry Roofing Company v. Wood…
“ Unlike the situation in the Buck case, Arkansas has not refused to grant a permit for interstate carriage of goods on state highways. It has asked these driver-owners to do nothing except apply for a permit as contract carriers are required to do by the state Act. And the State Commission here expressly disclaims any 'discretionary right to refuse to grant a permit for contract carriage where that carriage is in interstate commerce.' The state asserts no power or purpose to require the drivers to do more than register with the appropriate agency. ”
