Robert H. Jackson, United States v. National City Lines…
“ The scheme of the statutes, as I see it, is that the Attorney General may lay the venue in any district where he may properly serve one or more of his defendants. He may go ahead with his action against them, whether he is allowed to bring in others or not. Before he can bring in other parties than those properly served in the district, i.e., those 'inhabitant,' 'transacting business,' or 'found' there, it must be made to appear to the court that the ends of justice require that they be brought before the court, in which case they may be summoned from any district. ”
