The Minnesota District Court certified a medical monitoring class under (b)(2) and a national class of consumer claims under the Minnesota Consumer Protection Statutes under (b)(3). The Eighth Circuit found that the medical monitoring claims lacked coherence and could not be certified. With respect to the consumer claims, the Court did not preclude the possibility of certification, but reversed and remanded the certification order, requiring the District Court t conduct the choice-of-law analysis required by Shutts v. Phillips Petroleum. See Silzone Heart Valve Prod. Liab. Lit. v. St. Jude, 425 F.3d 1116 (8th Cir. 2005).
