w:Supreme Court of the United States, Toolson v. New York Yankees — Opinion of the Court
“ Congress has had the ruling under consideration but has not seen fit to bring such business under these laws by legislation having prospective effect. The business has thus been left for thirty years to develop, on the understanding that it was not subject to existing antitrust legislation. The present cases ask us to overrule the prior decision and, with retrospective effect, hold the legislation applicable. We think that if there are evils in this field which now warrant application to it of the antitrust laws it should be by legislation. ”
