After the adoption of the 2019 Convention on the Recognition and Enforcement of Foreign Judgments in Civil or Commercial Matters, the Hague Conference on Private International Law faces the question which methods should be employed to address matters relating to international direct jurisdiction in an efficient and politically feasible way. This paper will argue that the harmonization of international direct jurisdiction via a model law would not be conducive to foster legal certainty and predictability. Instead, the creation of a binding Protocol to the 2019 Hague Judgments Convention should be considered, unifying a core set of rules of international direct jurisdiction. In this way, the mixed-convention concept as developed by Arthur von Mehren in the 1990s in the context of the original Judgments Project would finally come to fruition. As the paper will demonstrate, this concept has the capacity to foster legal certainty and predictability, while being politically feasible.

海牙管辖权项目–海牙会议有哪些选择？

在2019年《关于承认和执行外国关于民事或商业事务的判决的公约》通过之后，海牙国际私法会议面临以下问题：应采用哪些方法在有效和政治上可行的方式处理与国际直接管辖权有关的事项办法。本文将论证，通过示范法协调国际直接管辖权将不利于促进法律确定性和可预测性。相反，应考虑为2019年《海牙判决公约》建立具有约束力的议定书，以统一国际直接管辖权的一系列核心规则。这样，亚瑟·冯·梅伦（Arthur von Mehren）在1990年代最初的审判项目的背景下提出的混合会议概念将最终实现。
