Mayer Brown’s global litigation and dispute resolution practice demonstrates considerable strength in complex commercial litigation, class actions, regulatory enforcement, and crisis-driven matters. The practice is driven by a team of senior litigators. In New York, Hank Bullock manages product liability and mass tort matters as well as major financial disputes, including high-stakes RMBS litigation. In Washington DC, Reginald Goeke represents clients before federal regulatory agencies and in consequential federal court proceedings, while Chicago-based Michael Olsen is a go-to trial strategist for commercial and class action litigation, including securities and commodities disputes and complex purchase and sale agreement litigation. In Los Angeles, Bronwyn Pollock is a tour de force in multi-party, multi-claim proceedings, most notably leading the defense of claims arising from the Maui wildfires.

Work highlights
Achieved a significant appellate victory on behalf of TC Energy Corp. in the Delaware Supreme Court, which reversed a $199m judgment previously entered against the company in connection with its $13bn acquisition of Columbia Pipeline Group Inc.
Secured a highly favorable resolution for our client Veolia S.A. and its US subsidiary in the high-profile Flint Water Crisis litigation—spanning a putative class action, thousands of individual suits in federal and state courts, and a parens patriae action by the Michigan Attorney General - culminating in a February 2025 settlement with the State of Michigan and approximately 26,000 claimants that effectively ends all current and future litigation against the company.
Secured a major win in the District Court for the Central District of California on behalf of the Board of Directors of the Motion Picture Industry Pension and Health Plans and fifty former and current directors. The ruling defeats up to $2.75 bn in claimed damages against the Board and its members and delivers a widely impactful win for the $5.5 bn plan serving major studios and unions across the entertainment industry.
