Case Comment : Olean Wholeale Grocery Cooperative, Inc. v. Bumble Bee Foods LLC, 31 F.4th 651 (9th Cir. 2022) (en banc)

The Ninth Circuit Court of Appeals recently held in an en banc ruling that district courts wield significant discretion when deciding whether to certify a class action containing potentially uninjured class members. The opinion rejected a “de minimis” rule, which, according to Defendants, other circuits adopted. The court properly focused on Rule 23’s broad text and the class mechanism’s core efficiency goals. However, the Ninth Circuit prematurely addressed the de minimis issue because its opinion reaffirmed the district court’s finding that each plaintiff was similarly situated. Still, in concluding Defendants failed to demonstrate a fatal dissimilarity within the class, the en banc panel effectively reasoned that opposition to predominance at class certification must attack evidence’s relevancy as to each class member rather than its sufficiency in proving the class claims
