Kirkland & Ellis LLP’s client base, which includes the Chicago Cubs, Bain Capital and EVA Air, reflects its breadth of expertise. Esteemed litigator James Mutchnik, based in Washington DC, was particularly active in 2015, and highlights included defending Health Care Services Corporation against allegations of suppressing competition for outpatient surgical services brought by a private clinic, and defending, as part of a cross-office team, Hitachi and Hitachi Display Products in multiple class actions alleging price-fixing of cathode ray tubes. In Chicago - another key office for antitrust work within the firm’s wide network - David Zott and Daniel Laytin are representing the Blue Cross Blue Shield Association in a series of putative class actions challenging, under antitrust laws, the structure of the association’s health insurance provision. Jay Lefkowitz in New York and Karen Walker in Washington DC together handled a number of pharmaceutical-related cases. Since publication, Matthew Reilly has joined from Simpson Thacher & Bartlett LLP.
