This book is a contribution to the evolving transatlantic dialogue on the conflict of laws as well as a tribute to Professor Arthur von Mehren from the Harvard Law School. It contains ten contributions that discuss the problems conflict of laws is facing in a globalized world. The first five contributions deal with current legal topics in international civil litigation and transatlantic judicial cooperation ranging from the design of judgments conventions in general to the recently adopted Hague Convention on Choice of Court Agreements and from current problems involving negative declaratory actions in international disputes to recent transatlantic developments relating to service of process and collective proceedings. The remaining five contributions focus on choice of law in international and transatlantic relationships. They cover comparative and economic dimensions of party autonomy, reflect on current discussions in the choice of law relating to intellectual property rights, and engage in critical discussions about the applicable law in antitrust law litigation, international arbitration, and actions for punitive damages.
