Integrated Litigation, Trial, and Crisis Management
We serve as national coordinating counsel, trial counsel, and appellate counsel in some of the largest and most significant mass tort, product liability, toxic tort, environmental, and public-health matters pending in courts throughout the United States and internationally. Our lawyers have managed portfolios involving tens of thousands of claims, coordinated nationwide and cross-border defense strategies, developed and executed large-scale discovery and expert witness programs, and tried and won cases in some of the country’s most challenging jurisdictions.
Our experience spans multidistrict litigation, coordinated state court proceedings, class actions, toxic tort and chemical exposure claims, catastrophic injury and wrongful death actions, environmental contamination disputes, CERCLA and Superfund litigation, natural resource damages claims, public nuisance litigation, consumer protection actions, product recalls, government investigations, and regulatory enforcement proceedings. We also routinely defend clients in parallel civil, criminal, regulatory, governmental, and legislative proceedings arising from major product, environmental, and public health events.
Scientific and Regulatory Depth
The scientific and technical issues underlying modern mass tort and environmental disputes are often as important as the legal issues. Our lawyers work closely with leading toxicologists, epidemiologists, hydrologists, engineers, geologists, physicians, industrial hygienists, material scientists, economists, and other experts to develop fact-based and science-driven strategies. We have extensive experience challenging unreliable expert testimony through Daubert, Frye, and equivalent proceedings and translating complex scientific issues into persuasive narratives for courts, regulators, juries, and other stakeholders.
Our regulatory capabilities are equally extensive. We advise clients on environmental compliance, product stewardship, chemical regulation, product safety, permitting, remediation, sustainability initiatives, environmental due diligence, and transactional risk management. We regularly represent clients before federal, state, local, and international regulatory authorities and help organizations anticipate and address emerging legal obligations before they become litigation or enforcement actions.
Addressing Emerging Risks
We are at the forefront of many of the issues reshaping the legal landscape, including PFAS and other chemicals of emerging concern, climate-related litigation and disclosure requirements, environmental justice initiatives, microplastics, sustainability and greenwashing claims, product safety and recall issues, advanced manufacturing, energy transition projects, critical infrastructure development, carbon capture and sequestration, supply chain compliance, and the rapidly evolving legal challenges associated with data centers and artificial intelligence infrastructure.
A Global, Multidisciplinary Platform
Our practice draws on the full strength of Mayer Brown’s international platform, integrating litigators, trial lawyers, environmental and regulatory practitioners, appellate advocates, government investigations lawyers, restructuring professionals, transactional attorneys, and public policy advisors into a unified team. This multidisciplinary approach allows us to address every aspect of a matter, whether it involves litigation, regulatory scrutiny, governmental investigations, commercial disputes, transactional considerations, or cross-border challenges.
Our appellate lawyers have argued more than 250 cases before the US Supreme Court and hundreds more before federal and state appellate courts. We serve as counsel to the Product Liability Advisory Council, and our teams throughout Europe and Asia regularly handle complex product liability, environmental, and group-action matters. This global reach provides clients with a coordinated strategy across jurisdictions and legal disciplines when the stakes are highest.
Whatever the challenge—whether a nationwide mass tort, a major product liability dispute, a contamination event, a Superfund matter, a product recall, a government investigation, a catastrophic incident, a public health controversy, or a transaction involving significant environmental risk—Mayer Brown offers a single destination for the legal, scientific, regulatory, and trial capabilities needed to manage the issue from beginning to end.
