The International Association of Procedural Law (IAPL) is a global association of law professors and scholars teaching and researching procedural law, with a specific interest in its various comparative dimensions. IAPL focuses on rules that enforce substantive rights and obligations in a judicial, administrative, and other legal proceeding such as arbitration and mediation. Since the 1950s, IAPL has regularly organized international conferences and seminars to facilitate scientific exchange among scholars from around the world.
In the present era of deglobalisation and growing intolerance, IAPL firmly stands for the values shared by its members:
Encouragement and support of young scholars working in comparative dispute resolution.
IAPL is proud of the multitude of languages spoken and cultures represented by its members.
IAPL membership is open to all researchers sharing these values and working in comparative procedural law. IAPL-Membership requires a solid academic qualification (usually a professorship) in the research field of the Association and a recommendation from two members of the Association.”

The multilingual International Journal of Procedural Law (IJPL) provides an international research platform for scholars and practitioners in the field of procedural law, especially in civil matters.
In addition to articles in five different languages examining current developments in judicial and alternative dispute resolution, the IJPL also publishes articles devoted to the theoretical foundations of procedural law. Contributions address legal issues from domestic, transnational or international perspectives, including comparative law and conflicts of law aspects. Consequently, the IJPL is not only of interest for scholars but also for practitioners in charge of cross-border cases.

Comparative Procedural Law and Justice (CPLJ) is a global project on comparative civil justice, organized by the former Max Planck Institute Luxembourg for Procedural Law and supported by the Luxembourg Research Fund FNR (FNR - O19/13946847).
Officially launched in September 2020, it was the flagship research project of the Department of European and Comparative Procedural Law of the Max Planck Institute Luxembourg. In January 2024, the Max Planck Institute Luxembourg and CPLJ were transferred to the University of Luxembourg.
Burkhard Hess was the founding director of the Max Planck Institute for Procedural Law where CPLJ was originally launched. Since September 2024, he has been continuing the project as leading editor from his new chair and with the assistance of his team at the University of Vienna.
