Frank Murphy, Thomson v. United States/Dissent O. Douglas…
“ The control and responsibility test provides a fair measure of the grandfather rights. He who shows that he has been and is an independent contractor has established his claim to the transportation business as clearly as any connecting carrier. The fact that the transportation service offered is closely integrated and held out to the public as such does not mean that segments of the line-haul operation may not comprise separate enterprises. To attach grandfather rights to the separate segments is not to grant multiple rights. It is to allow those rights to follow ownership of the enterprise. ”
