White & Case LLP has a very impressive offering in the field of litigation that covers a large variety of cases, often dealing with challenging issues. The firm’s practice is second to none in the field of shareholders' conflicts, and corporate and insolvency-related cases, where it manages high-end mandates on behalf of leading investment firms through the excellent Diane Lamarche and Félix Thillaye. Additionally, the practice is a go-to for high-stakes consumer law issues, including class actions and regulatory lawsuits, notably linked to the digital world, with several leading digital companies as regular clients. The highly regarded Kami Haeri, competition and distribution partner Yann Utzschneider and Alexandre Kiabski are also highly recommended.
