John NeuwirthWeil, Gotshal & Manges LLP

The firm is at this top in this practice area‘, says a client of Weil, Gotshal & Manges LLP, noting that it has ‘an experienced team that gets great results‘. The firm has a strong bench of M&A litigators and is not only a leading player in the Delaware Court of Chancery, but also in other fora across the US. The team is involved in emerging areas of the market, notably SPAC-related litigation, largely due the heavy involvement of its transactional lawyers in SPAC and de-SPAC transactions. It recently advised Churchill Capital Corp. III in stockholder litigation in Delaware following its $11bn merger with healthcare data analytics firm MultiPlan. John Neuwirth, who led the defense of Churchill, Joseph Allerhand and Caroline Zalka are co-heads of the ‘super-sophisticated and experienced‘ securities litigation practice, in which veteran litigator Jonathan Polkes and emerging talents Joshua Amsel and Evert Christensen are play key roles. Christensen worked alongside Neuwirth to defend Brookfield Asset Management in a precedent-setting matter that struck down a key point of law in Gentile v. Rossette concerning a “dual-natured” claims precedent that allowed certain claims to be both direct and derivative. All mentioned lawyers are based in New York.
