A sometimes-overlooked aspect of class action law is how class certification rules interact with the Rules Enabling Act, which provides that rules of procedure and evidence “shall not abridge, enlarge or modify any substantive right.” 28 U.S.C. § 2072(b). Some class actions attempt to use the class action device to evade obstacles to obtaining individual…

One of the first significant class certification-related decisions of 2023 comes from the Fifth Circuit. While some trial courts hesitate to strike class action allegations on the pleadings, the district court here concluded very early in the case that it was clearly inappropriate for class certification. The Fifth Circuit agreed, in a published opinion that…

Last week the Eleventh Circuit addressed an issue that many class action practitioners probably haven’t thought much about: whether approval of a class action settlement requires that each class member obtaining relief have Article III standing to sue. Defendants typically want a broad class definition because they are focused on finality and buying peace. Plaintiffs…

The Ninth Circuit recently addressed an issue that tends to arise frequently in class certification motion practice: how trial courts should apply the predominance requirement where appellate decisions have said that the need to calculate individualized damages generally is not sufficient on its own to defeat class certification, but some putative class members likely have…

I used to say that denials of class certification on numerosity grounds were rare and that usually it was futile to oppose class certification on that ground. That’s becoming less true as some circuits, including the Third Circuit, have adopted a stricter approach to how plaintiffs must establish numerosity. If Plaintiffs are using an estimate…

A recent Seventh Circuit decision makes an important point about how the principle that a court generally need not resolve the merits to decide class certification is bilateral – it applies to both affirmative claims and defenses. The plaintiff argued that the district court erred in denying class certification because there was one key defense…

Last week the Fifth Circuit issued a short opinion that made an important point that does not arise often in class certification decisions. Class certification failed because the plaintiffs’ proposed theory of liability would benefit only some class members and disadvantage others, who would be overpaid if the plaintiffs’ theory were correct. For that reason…

Numerous class action suits have been filed against auto insurers regarding the valuation of vehicles that are total losses. These cases typically allege that insurers are undervaluing vehicles in some common way or in violation of a state regulation. The Ninth Circuit recently affirmed the denial of class certification in a published decision that I…

On August 30, 2021, the U.S. Court of Appeals for the First Circuit issued a decision in Bais Yaakov of Spring Valley v. ACT, Inc. that addresses how plaintiffs can satisfy the predominance requirement in federal class actions. (The opinion (“Op.”) is available here). The decision held that on the facts of this case,…
