Frank Murphy, United States v. N. E. Rosenblum Truck Lines…
“ Congress has set that forth for us broadly in the declaration of policy [6] -in essence it is the regulation of transportation by motor carriers in the public interest so as to achieve adequate, efficient and economical service. To implement that policy Congress forbade common carriers by motor vehicle to operate in interstate commerce without securing a certificate of public convenience and necessity from the Commission, [7] and required contract carriers to secure a permit from that body. ”
