Messner v. Northshore Univ. Healthsystem

The Federal Trade Commission found that a merger between a health system and a hospital violated the Clayton Act, 15 U.S.C. 18. Plaintiffs sought treble damages and certification of a class of patients and third-party payors who allegedly paid higher prices for care. Under FRCP 23(b)(3), a class may be certified only if questions of law and fact common to members predominate over questions affecting only individuals in the class. Plaintiffs proposed to rely on economic and statistical methods used by the FTC and defendant's economic experts to analyze antitrust impact. The "difference-in-differences" method estimates price increases resulting from exercise of market power rather than from other factors. The district court denied certification, concluding that the expert had not shown that his methodology could address impact on a class-wide basis. The Seventh Circuit granted interlocutory appeal, vacated, and remanded. Although plaintiffs' expert initially believed that the health system did increase prices uniformly across all services, he acknowledged that it might not have done so, and explained how his methodology could show impact to the class despite such complications. The degree of uniformity the court demanded is not required; "it is important not to let a quest for perfect evidence become the enemy of good evidence." View "Messner v. Northshore Univ.
