Abstract: We live in a world in which the victims of cross-border mass torts de facto (not de jure) have no court to turn to in order to pursue legal action against American multinational corporations when they are responsible for disasters. The only way to provide a fair and legitimate process for both victims and corporations is to create an International Court of Civil Justice (ICCJ). This Essay seeks to start a conversation about this novel institutional solution. It lays out both a justice case, from the plaintiffs’ viewpoint, and an efficiency case, from a corporate defendant’s viewpoint, for why a world with an ICCJ would be a better place. The Essay also provides an initial blueprint for such an ICCJ. In so doing, it explains why an ICCJ is politically viable and may, specifically, appeal to rather than repel the least likely constituency: corporate America. The Essay concludes with a call for action and a research agenda.
