Celebrating MPEiPro 500th Article

Since its inception, Max Planck Encyclopedia of International Procedural Law has provided pioneering and meticulously peer-reviewed research on areas of international law that are often under-explored. Today, we proudly celebrate the publication of the Encyclopedia’s 500th article. To celebrate the success of this important milestone, we have collated key articles contained within MPEiPro and made them freely available for a limited time only.
