Among the best for highly complex and potentially "bet the company" legal issues’, Kirkland & Ellis LLP’s litigation team is ‘client-oriented, creative and smart’. With 500 attorneys in the litigation practice firmwide, it is one of the largest groups in the market. Of particular note is the team’s broad experience in state and federal courts - including at appellate level - and in arbitration proceedings. A team that includes Mark Filip, Donna Welch, Leslie Smith and Jennifer Levy is representing Allergan in the closely watched opioids investigations, which span state and federal governmental investigations, congressional inquiries and civil lawsuits. Elsewhere, James Hurst and Andrew Kassof secured a victory for Abbott Laboratories in a False Claims Act (FCA) jury trial in the Northern District of Texas, which was affirmed by the Fifth Circuit in May 2017. Richard Godfrey is a ‘brilliant class action lawyer’. Andrew McGaan and Washington DC-based Eugene Assaf are also recommended. Above-named partners are based in Chicago unless otherwise stated. In April 2018, star litigator Sandra Goldstein joined from Cravath, Swaine & Moore LLP.
