In Rozema v. Marshfield Clinic, a class action brought by the plaintiffs charged a group of health-care providers with conspiracy to divide the market. The named plaintiffs represented a class of health-care purchasers in an eight-county area. The court noted that the plaintiff failed to produce enough evidence demonstrating a link between the defendant and another co-defendant. The defendant had brought a motion for summary judgment on many of the charges, however, and only one was granted. This was the final disposition of the case, as far as my research allows. NOTE: The defendant in this case was also involved in antitrust litigation with Blue Cross Blue Shield of Wisconsin. There was a Posner decision, 152 F.3d 588 (7th Circ. 1998)) which concentrated mostly on damages and is not in line with the issues discussed here.
