Complex cross-border transactions and high-stakes litigation are hallmarks of Mayer Brown’s prominent antitrust practice. Recent highlights include high-profile defenses in animal protein and agricultural cases, where the team secured summary judgments and notable settlements in actions brought by state attorneys general. Additional successes include a grey-market goods distribution case and the defense of class actions involving student-athlete compensation. Britt Miller, based in Chicago, co-chairs the practice and frequently leads high-stakes antitrust litigation involving allegations of price-fixing, monopolization, and conspiracy. William Stallings and Gail Levine, co-chairs based in Washington DC, bring significant litigation expertise to the practice. Also in DC, Carmine Zarlenga has represented national and international companies in over 50 state and federal courts across the US. Operating from Chicago, Matthew Provance adds strength to the team with his deep knowledge of the technology and data privacy sectors.
