Tom C. Clark,
United States v. J. B. Montgomery…
“ The validity of this restriction is the sole challenge raised in this proceeding.The Commission contends that § 212 (c) , read in the light of its background, is a 'grandfather clause.' Its purpose, therefore, is merely to continue, without expanding, the authority of those contract carriers whose operations are lawful under United States v. Contract Steel Carriers, Inc., 350 U.S. 409, 76 S.Ct. 461, 100 L.Ed. 482 (1956) , by revoking their contract carrier permits and issuing in lieu thereof common carrier certificates. ”
