In many privacy and other technology-related class actions, the question of whether consumers consent to the practice at issue is central.  In these cases, class action defendants have defeated motions for class certification by successfully arguing that consent is an individualized issue that is not susceptible to common proof.  And though class action plaintiffs may try and avoid this problem by excluding consenting individuals from their class definition, that solution can create new problems, including impermissible “fail-safe” classes—i.e., classes that cannot be defined until a case is resolved on the merits.Continue Reading Sixth Circuit Denies Permission to Appeal Class Certification Order Raising Questions of Consent and Fail-Safe Classes

Last month in In re: Keurig Green Mountain Single-Serve Coffee Antitrust Litigation, the Southern District of New York denied certification to a proposed class of direct purchasers who alleged that Keurig, a manufacturer of branded coffee pods and brewers, violated antitrust laws by allegedly suppressing competition from generic coffee pod manufacturers.  Although the plaintiffs offered statistical evidence suggesting that Keurig’s coffee pod prices were elevated on average, the court held that individual issues of antitrust impact predominated over common questions because Keurig directly negotiated prices with large buyers that might fully offset any increase in average prices.Continue Reading Aggregate Damages Model, List Prices Insufficient to Demonstrate Classwide Antitrust Injury, Says Federal District Court

In a win for implied preemption, the Ninth Circuit recently affirmed dismissal of supplement marketing claims under California’s Unfair Competition Law (UCL).  The case, Bubak v. Golo, LLC, No. 24-492 (9th Cir. Oct. 9, 2025), held that the plaintiff’s UCL claim was impliedly preempted because it depended entirely on alleged violations of the federal Food, Drug, and Cosmetic Act (FDCA), which may be enforced only by the federal government.Continue Reading Ninth Circuit Affirms Dismissal of Supplement Marketing Claims as Impliedly Preempted

Courts continue to grapple with the type of “concrete harm” that is required to confer Article III standing under TransUnion LLC v. Ramirez, 594 U.S. 413 (2021), particularly in data breach and privacy class actions.  On October 14, the Fourth Circuit contributed to this debate, holding that allegations that plaintiffs’ driver’s license data had been leaked and appeared on the dark web were sufficient to establish standing.

Holmes v. Elephant Ins. Co., — F.4th —, 2025 WL 2907615 (4th Cir. 2025), started with a 2022 data breach of Elephant Insurance Company’s networks.  Id. at *1.  Plaintiffs were Elephant customers whose driver’s license numbers were compromised in the breach.  Id.  They sued Elephant for alleged harms stemming from the breach.  Id. at *3.  Two plaintiffs specifically alleged that they had found their driver’s license numbers on the dark web; the others did not.  Id. at *2.  The district court dismissed plaintiffs’ claims, holding that none of the alleged injuries were sufficient to confer standing.  Id.  But the Fourth Circuit disagreed in part, reversing the lower court’s dismissal of the two plaintiffs who alleged that their driver’s license information appeared on the dark web, but affirming dismissal of the other two. Continue Reading Standing in the Dark:  Fourth Circuit Finds Standing for Driver’s License Information on the Dark Web
