319 F.R.D. 158
E.D. Pa.2016Background
- This is a class-certification decision in an antitrust suit alleging that the Eastern Mushroom Marketing Cooperative (EMMC) and members conspired (1) to fix minimum distribution prices for fresh Agaricus mushrooms and (2) to restrict supply by acquiring farms and placing deed restrictions. Plaintiffs seek certification of a nationwide (non‑Western U.S.) direct‑purchaser class for purchases from Feb. 4, 2001 to Aug. 8, 2005.
- The market is described as a three‑tier “cake”: growers (top), distributors/packagers (middle), and purchasers (retailers, food‑service, processors) at the base. Some defendants are integrated grower/distributors; others are growers only or distributors only.
- Plaintiffs rely heavily on economic expert Professor Einer Elhauge (regression analyses, before/after pricing, supply‑control model) to show classwide impact and aggregate damages. Defendants counter with experts (Dr. John Johnson, Dr. Rigoberto Lopez) challenging market definition, heterogeneity, and the models’ ability to establish classwide injury and damages.
- The Court previously held the price‑fixing claim is governed by the rule of reason and the supply‑control (deed restriction) claim is per se unlawful. The Illinois Brick direct‑purchaser rule and its exceptions (cost‑plus, co‑conspirator, control/owned) loom large because many purchasers bought from distributors rather than directly from growers.
- The Court applied Rule 23’s “rigorous” analysis, weighed the competing expert evidence, and concluded plaintiffs satisfied numerosity, commonality, typicality, adequacy, ascertainability, predominance, and superiority — certifying the class but granting summary judgment dismissing Diversified Foods’ individual claims for lack of antitrust standing under Illinois Brick.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Class certification under Rule 23(a) & (b)(3) | Plaintiffs contend common evidence (EMMC documents, market structure, Elhauge’s models) shows conspiracy, impact, and aggregate damages suitable for class treatment. | Defendants argue heterogeneity (product, regional markets, distributor relationships), Illinois Brick issues, and flaws in expert models defeat commonality, predominance, and ascertainability. | Court certified the class: found numerosity, commonality, typicality, adequacy, ascertainability, predominance, and superiority satisfied. |
| Illinois Brick (direct purchaser and exceptions) | Plaintiffs define class to include direct purchasers from EMMC members or their co‑conspirators/controlled affiliates and argue distributors were part of the conspiracy or controlled. | Defendants maintain many class members bought from independent distributors (indirect purchasers) and that co‑conspirator or control exceptions do not uniformly apply, requiring mini‑trials. | Court held Illinois Brick issues do not defeat ascertainability or certification; class limited to those who purchased directly from defendants or fall within established exceptions; plaintiffs retain burden to prove standing as to specific relationships. |
| Proof of antitrust impact (predominance) | Plaintiffs rely on (1) Bogosian presumption for supply restriction, (2) documents showing unified pricing and EMMC contemporaneous admissions, (3) market structure (commodity, concentrated, high barriers), and (4) Elhauge’s regressions and before/after analyses to show classwide impact. | Defendants argue Bogosian is limited (esp. under rule of reason), regional markets exist, product differentiation and purchaser heterogeneity undermine regressions, and the data set omits many defendants/class members. | Court found impact susceptible to common proof when considering the totality of evidence (documents, market‑structure, Elhauge’s aggregate and individual regressions, supply model); Bogosian alone insufficient but supports combined approach; predominance met. |
| Classwide damages methodology | Plaintiffs present Elhauge’s aggregate regression damages and a supply‑control damages model, and propose later allocation to injured members. | Defendants contend models produce an average effect insufficient to prove each member’s injury, may over‑ or under‑include damages from vertical relationships, and lack data for some defendants. | Court held plaintiffs offered statistically feasible classwide damages methods consistent with liability theories; aggregate damages can be estimated classwide with individual allocation later; Comcast concerns acknowledged but not fatal here. |
