Under Federal Rule of Civil Procedure 23(b)(3), a court may certify a suit for damages as a class action when “there are questions of law or fact common to the class” that “predominate over any questions affecting only individual members.” Similar certification standards apply when a plaintiff seeks to certify a collective action under the Fair Labor Standards Act (FLSA). Yesterday, in its highly anticipated decision in Tyson Foods, Inc. v. Bouaphakeo (pdf), the Supreme Court affirmed the certification of an FLSA collective action where the evidence tying class members together was a study of a representative sample of similarly situated workers.

The Eighth Circuit recently issued a decision reversing class certification for lack of commonality.

In Smith v. ConocoPhillips Pipe Line Co., the Eighth Circuit considered a class action proceeding on a nuisance theory against the owner of a pipeline. The plaintiffs, who owned property near the pipeline and were suing on behalf of a

There seem to be two prevailing conceptions of class actions.  In one view, a class action is a way of determining many similar claims at once by evaluating common evidence that reliably establishes liability (and lays a ground work for efficiently calculating damages) for each class member.  That is, the class device produces the same results as individual actions would, but more efficiently.  In the other view—one we consider misguided—a “class” of plaintiffs complaining about similar conduct can have their claims determined through statistical sampling even if no common evidence will provide a common answer to common factual or legal questions. Instead, this theory holds, the results of mini-trials can simply be extrapolated to the entire class, even if individual results would vary widely.

Last week, the Ninth Circuit took a step deeper into the second camp in Jimenez v. Allstate Insurance Co. (pdf), delivering a ringing endorsement of statistical sampling as a way to establish liability as well as damages.

Sometimes it’s hard to know who’s in a class without substantial individualized inquiries.  Can a court certify a class of persons with allegedly similar injuries by pigeonholing the question of class membership as a question of damages to be determined later?  Not so fast, the Fourth Circuit held in EQT Production Co. v. Adair (pdf).  

Suppose that you’re a trial court considering a motion for class certification.  And suppose that the parties present you with two competing statutory interpretations.  One legal standard permits the case to be adjudicated with common evidence.  And the other standard would require  individualized inquiries.  What should you do?  Should you decide what the law is

At its conference on January 10, the Supreme Court can get serious about fixing consumer class actions. The Justices should take up that challenge, because it will consider two certiorari petitions that seek review of class certifications—involving alleged “moldy odors” in high-tech front loading washing machines—that are prime examples of what has gone wrong with

Here’s the situation: You’re facing a class action in federal court in which the plaintiffs define the putative class so broadly as to encompass many people who weren’t injured by the alleged wrongdoing. For example, consider a false-advertising class action on behalf of “all purchasers” of a product that the vast majority of purchasers would

We’ve been blogging about the Second Circuit’s decision in NECA-IBEW Health & Welfare Fund v. Goldman Sachs (pdf), which held that a named plaintiff in a securities fraud suit might have standing in some situations to assert class action claims regarding securities that he or she never purchased. Yesterday, the Supreme Court denied (pdf) Goldman’s

I previously blogged about the Second Circuit’s troubling decision in NECA-IBEW Health & Welfare Fund v. Goldman Sachs & Co. (pdf), 693 F.3d 145 (2d Cir. 2012), which invented a “class standing” doctrine allowing a named plaintiff in a class action to assert Securities Act claims regarding securities that he or she never purchased.
