John at Discriminations has this post, about the good law made by the cases in which law schools have lost.
At one time, a similar point could be made about the Virginia State Bar cases involving solicitation of clients. See Goldfarb v. Virginia State Bar, 421 U.S. 773 (1975); Brotherhood of Railroad Trainmen v. Virginia ex rel. Virginia State Bar, 377 U.S. 1 (1964); Consumers Union of U.S., Inc. v. Virginia State Bar, 688 F.2d 218 (4th Cir. 1982).
