  • Successfully defended a European investment group, with each side to bear its own costs, in Delaware Chancery Court in connection with a multi-year litigation in which plaintiff, one of the world’s largest private equity firms, raised the novel argument that defendant’s affiliate’s litigation funding activities violated a release clause.
