In the U.S., we have successfully litigated cartel, merger, and monopolization cases, including winning motions to dismiss, defeating class certification, obtaining summary judgment, and prevailing at hearing and trial. Our lawyers develop proactive strategies, with a global, results-driven outlook.
In Europe, we regularly represent clients before EU and national courts on the full range of EU and national competition issues, including stand-alone and follow-on damages actions, collective proceedings, and appeals against EU Commission, the CMA, and national antitrust decisions. Several of these cases have resulted in landmark judgments at EU and national level.
Our integrated global practice encompasses antitrust litigation matters that arise in multiple jurisdictions, where we leverage best-in-class teams from our leading global antitrust and litigation practices. We have successfully advised clients in damages litigation, criminal matters, and administrative proceedings arising simultaneously in the United Kingdom, France, Germany, Italy, the U.S., and other key jurisdictions worldwide.
Wherever the case may arise, we combine vigorous advocacy with a deep understanding of antitrust law and economics, informed by our litigation work across all areas of antitrust law and our extensive experience before antitrust agencies. Our regulatory insight enables us to anticipate enforcement trends and craft strategies that draw on both courtroom excellence and frontline regulatory experience.
