By their very nature, class actions are complex and present companies with potential substantial exposure. The defense of these cases involves a sophisticated approach by experienced counsel. Katten's Class Action Litigation group has extensive experience defending our clients in large, high-stakes class actions and mass actions in federal and state courts across the country for a wide range of industries, including consumer financial services, food and beverage, and advertising. Our attorneys formulate and execute innovative defense strategies that meet our clients' legal needs and limit the negative impact of litigation on their business operations.

A record of success

The group has a strong track record of successfully resolving cases, either by prevailing on motions to dismiss or, in class actions, by defeating class certification. Depending on our clients' business objectives, we are also adept at leveraging favorable settlements. Underlying this track record is a deep understanding of our clients' businesses, coupled with a comprehensive knowledge of the regulatory framework and consumer protection laws that affect and often drive these cases.

Preventive measures

We counsel our clients on ways to avoid becoming targets, and to that end, we closely monitor new case filings and the evolving tactics of the plaintiffs' bar. We are experienced in the use of arbitration agreements and class action waiver clauses, and we regularly advise our clients on using them to prevent future actions.

Plaintiffs allege our clients improperly charge overdraft fees in violation of Regulation E of the Electronic Fund Transfer Act. We obtained involuntary dismissals of some cases, resolved others and are actively litigating the remainder.
  • Represent client before the FTC in an effort to prevent filing of an action against it for alleged violations of federal consumer protections laws and the Federal Trade Commission Act.
  • Represented title lending company in putative class action in Circuit Court for City of St. Louis, Missouri. Plaintiff alleged that although company was licensed by State of Missouri to make small, short-term "payday loans," its practices were unconscionable and violate the Missouri Merchandising Practices Act. We were hired mid-case to try question of whether class action waiver contained in client's arbitration clause was enforceable. Trial court found that class waiver itself was inherently unconscionable. On direct appeal, Supreme Court of Missouri reversed trial court, and remanded with specific instructions to examine unconscionability again (on grounds that had already been addressed by the trial court).
  • Represent individuals in case of first impression. Florida Supreme Court sided with our clients, reversing court below and rejecting plaintiffs' argument that arbitration agreement including class waiver is unenforceable under Florida law.
