Client SatisfactionDarrois Villey Maillot Brochier advises prominent French and international clients across the spectrum of competition matters. The firm remains a leading reference in the market for complex, high-profile merger control cases before the FCA and EC, and is also frequently active in antitrust investigations and related appeals, and in state aid matters. In addition, the team has a thriving practice in the field of follow-on damages actions, appearing before the French courts on behalf of both plaintiffs and defendants. Didier Théophile, a renowned competition lawyer with particular expertise in the regulated sectors, leads the practice. Guillaume Aubron stands out for his impressive experience in both merger control and behavioural matters, and Constance Bocket, who was promoted to partner in January 2024, is also an up-and-coming practitioner.
