Expansion of the MPEPIL Academic Advisory Board

The Academic Advisory Board of the Max Planck Encyclopedia of Public International Law (MPEPIL) has been expanded and now includes 17 leading academics and renowned experts in public international law.

The MPEPIL is entering a new era. With more than 1,750 entries published as of January 2022, covering virtually every aspect of the substance of international law, the primary focus of the advisory board and the editorial team will be to keep up with the developments in this dynamic field of law by continuously updating existing entries whilst adding new ones on emerging topics. 

With the members’ diverse backgrounds and areas of expertise, the advisory board is well equipped to oversee this vast project and to give strategic advice on how to optimize its processes and content, with the aim of maintaining the Encyclopedia’s reputation as the most trusted reference work in international law.
