International litigation in United States

Cleary Gottlieb Steen & Hamilton

Led by Carmine Boccuzzi, the New York-based multi-disciplinary team at Cleary Gottlieb Steen & Hamilton utilizes its ‘brilliant knowledge of domestic litigation rules and practices' and 'deep understanding of international litigation particularities’ in its representation of claimants and defendants. The team acts for large domestic and multinational financial institutions, international organizations, corporations and trade associations in complex general commercial litigation across all level of the US judicial system, ranging between local civil courts up to the US Supreme Court. With more than one third of its US-based lawyers being litigators, the team has formidable litigation expertise, complemented by wider strengths in core areas such as financial services, corporate, regulatory and antitrust. The global group’s unified office approach also ensures that the group can rely upon skilled colleagues from across the firm’s network to help ensuring its clients’ success in cases involving fraud, breaches of contracts and fiduciary duties, unfair competition, and negligence, among others. Among its recent headline highlights, the team represented multiple parties in Madoff-related litigation, and is also acting for Bosch in litigation arising out of the diesel emissions scandal in the automobile manufacturing sector. Lawrence Friedman and Jonathan Blackman scored a win for Crédit Lyonnais and National Westminster Bank in longstanding litigation proceedings involving the US Anti-Terrorism Act. Securities litigation specialist Meredith Kotler departed to Freshfields Bruckhaus Deringer LLP in October 2019, but the group’s offering remains strong, with Jared Gerber a key contact for securities fraud work and Roger Cooper standing out in the securities class actions space.
