In Paul Herrup and Ronald A. Brand, A Hague Convention on Parallel Proceedings, 63 Harvard International Law Journal Online 1(2022), available at and, we argued that the Hague Conference on Private International Law should not undertake a project to require or prohibit exercise of original jurisdiction in national courts. Rather, the goal of current efforts should be to improve the concentration of parallel litigation in a “better forum,” in order to achieve efficient and complete resolution of disputes in transnational litigation. The Hague Conference is now taking this path. As the Experts Group and Working Group have moved forward on the Parallel Proceedings Convention project, however, there has been difficulty in leaving behind existing approaches that have not led to acceptable solutions. In particular, the work has failed to look far beyond the traditional civil law lis alibi pendens and common law forum non conveniens approaches to parallel litigation, or a focus on questions of jurisdiction.

We believe the time is ripe for fresh thinking that reflects Twenty-first century realities in finding a workable approach to parallel litigation. In this article, we build on the previous article by discussing a possible architecture and some of the critical features of a parallel proceedings convention geared to moving litigation to the better forum.
