Second Circuit Rejects the Use of "Aggregate Proof" of Causation in a Putative Consumer Class Action
By John Stigi and Eric O’Connor
In UFCW Local 1776 v. Eli Lilly & Co., No. 09-0222-CV, 2010 WL 3516183 (2d Cir. Sept. 10, 2010), the United States Court of Appeals for the Second Circuit reversed an order of the United States District Court for the Eastern District of New York certifying a class of third party payors (“TPPs”) consisting of unions and insurers who underwrite the purchase of drugs prescribed by physicians in an action against pharmaceutical manufacturer Eli Lilly & Co. (“Lilly”) alleging civil violations of the Racketeer Influenced and Corrupt Organizations Act, 18 U.S.C. §§ 1962, 1964 (“RICO”). At the core of this decision is the Second Circuit’s rejection of the use of “aggregate proof” of causation in the consumer class certification process.
