For more than 30 years Gibson Dunn has provided  counsel on the complete range of legal issues and challenges that arise in environmental and mass tort areas.  Our group's members represent clients in civil and criminal litigation before U.S. federal and state courts as well as administrative agencies.  The lawyers on our team have been involved in a number of high-profile, precedent-setting matters leading to published decisions that affect or control the interpretation of applicable laws.  We are also active in counseling our clients about various forms of alternative dispute resolution. 

Environmental and mass tort litigation, like other commercial litigation, benefits from aggressive discovery and early, targeted motion practice to help defeat or at least define and narrow claims.  Once claims are narrowed and ambiguity in claims is eliminated, settlement is often significantly easier.  We have been successful in applying this approach to cases involving both government and nongovernment litigants.
