Class Action Litigation


MG+M’s class action practice is diverse and robust. Primarily, MG+M attorneys help clients navigate class action defenses with a nuanced comprehension of the legal intricacies and strategic considerations inherent to complex and multifaceted litigation. At MG+M, we take a leading role in protecting clients confronted with class action lawsuits, with particular experience with environmental claims like PFAS litigation and the Deepwater Horizon incident. Our diverse practice also includes plaintiffs-side class actions and global recovery programs, particularly in the anti-trust context. Our attorneys’ knowledge of class action from the defense perspective, makes us uniquely situated to prosecute class actions against known anti-trust violators, whether through affirmative “opt-out” litigation or through the claims process on settlement funds. Our firm has helped clients recover multiple millions of dollars in these matters.

As industry leaders, we take an aggressive approach to both prosecute claims and protect clients against the dangers of class actions. These cases can present unique challenges and we understand the risks associated with brand reputation, operations and bottom line. We help clients navigate these risks and diligently pursue the result that will best support the client’s business goals. Throughout our representation, effective communication, careful documentation and a proactive approach to legal challenges are crucial. MG+M’s method involves pursuing cost-effective, business-focused solutions, whether through defeating class certification, winning dispositive motions, implementing discovery strategies, or maximizing claim recovery. The goal is to protect our client’s interests in the most efficient way possible for an outcome with the most value.
