Sidley Austin LLP‘s practice has been described by clients as ’strategic thinkers, particularly strong and compelling legal writers, with a deep bench.’ That reputation is reflected in a workload demonstrating the full spectrum of competition matters, spanning merger control, investigations, enforcement, counseling, and high-stakes litigation. The practice benefits from broad geographic depth across major US markets and a team accustomed to advising across regulated and scrutinised industries. Benjamin Nagin, co-leader of the global group from New York, is known for leading hard-fought litigation and for his work at the cutting edge of antitrust issues, including technology, AI, financial services, and labour-related matters. Carrie Mahan is consistently trusted with high-stakes engagements and recognised for her authority in the field, operating out of Washington, DC.. In Miami, Larry Silverman brings extensive trial experience, particularly in antitrust and class action litigation, with expertise in distribution and pricing issues.
