John Marshall Harlan II,
United States v. J. B. Montgomery…
“ Congress evinced an intent not to impose any new limitations on carriers subject to conversion, and, in view of the greater obligations owed by common carriers and the more extensive regulation to which they are subject, it is difficult to argue that the maintenance of existing carriage privileges will advantage the converted carriers to the possible prejudice of other common carriers. The Commission, therefore, may not include in the common carrier certificate a Keystone restriction that renders impermissible operations allowed under the contract carrier permit. ”
