Class Action


Lawyers bringing cases for plaintiffs have become more sophisticated and aggressive in using class actions. More than ever, businesses are at risk of class action litigation.

The class action lawyers at McDermott include litigators with extensive experience defending a wide variety of class action lawsuits. We obtain pre-certification dismissals and summary judgments, defeat class certification and obtain de-certification of classes in cases. We also argue appeals of class certification rulings in state and federal appellate courts across the United States.
