International litigation

Within: International litigation

Shearman & Sterling LLP is ‘a truly international firm that is more globally integrated than some of its competitors’ and has ‘a reputation that extends far beyond the US’. The firm advises multinational corporations and financial institutions on high-profile matters including global investigations, Foreign Corrupt Practices Act (FCPA) matters and US-based litigation involving non-US entities. In New York, global head of litigation Adam Hakki, who advised underwriters of the Alibaba IPO on a securities class action, and deputy head of the litigation department Richard Schwed are recommended. Schwed regularly handles cross-border matters relating to contested mergers and acquisitions, antitrust cases and financial services litigation. With Henry Weisburg and Washington DC-based Christopher Ryan, he sought enforcement of arbitral awards to secure a $50bn payment from the Russian Federation after its expropriation of investments in the former Yukos Oil Company. Paula Anderson is a rising star.
