Welcome to the Max Planck Encyclopedia of Comparative Constitutional Law

The Max Planck Encyclopedia of Comparative Constitutional Law (MPECCoL) provides a high level of analytical coverage of constitutional law topics in a comparative context. MPECCoL articles address a focused range of topics that provide the best coverage of the essence, character, development, and history of constitutional law from a global perspective.

 


Celebrating MPECCoL 300th Article

Since 2017, Max Planck Encyclopedia of Comparative Constitutional Law has overcome the geographical and ideological differences frequently encountered in comparative constitutional studies through a truly global approach. Today, we proudly celebrate the publication of the Encyclopedia’s 300th article. Looking back, we believe that the choice of entries and the selection of authors reflects the diversity of constitutional conceptions and ideas existing in the globalised world of today. To celebrate the success of this important milestone, we have collated popular articles contained within MPECCoL and made them freely available for a limited time only.
