This important book systematically analyses the private international law issues regarding private antitrust damages claims which arise out of transnational competition law infringements. It identifies those problems that need to be considered by injured parties, defendants, judges and policy-makers when dealing with cross-border private antitrust damages claims in a global context. It considers the post Brexit landscape and the implications in cross border private proceedings before the English courts and suggests how the legal landscape should be developed. It also sets out how private international law techniques could play an increasingly important role in private antitrust enforcement. Comprehensive and rigorous, this is required reading for scholars of both competition litigation and private international law.
