The Multiplication of Authorities in Global Governance Institutions (MAGGI)

Max Planck Research Group, headed by Janne Mende, funded by the Max Planck Society (2020-2025).

Mission and Profile

The Max Planck Research Group on "The Multiplication of Authorities in Global Governance Institutions" (MAGGI) focuses on the authority of state, intergovernmental and non-state actors in global governance, especially in the UN and the EU. We investigate which actors yield which form of authority – and how their authority can be democratically embedded. Operationalizing authority as governance power that is legitimated by a connection to public interests, the Research Group seeks to identify different forms of authority between and beyond public and private roles, in order to address the challenges for democracy on a global level.
The Research Group MAGGI is closely affiliated with the Research Project International Public Authority, which is led by Armin von Bogdandy. Additionally the Research Group leads the Human Rights Discussion Group.

The Research Group organizes a workshop in July 2023 at which internal and external scholars bring in their research on the topic, preparing a joint publication.

Call for Papers

The Max Planck Research Group MAGGI invites submissions for a special issue/edited volume on the Multiplication of Global Governance Authority: Contestation, In/formalization, and Constellations. Further information, including a detailed outline and schedule, are in the pdf.

Please submit your 250-words proposal by December 17th. Accepted paper-givers will be invited to an authors' workshop at the Max Planck Institute for Comparative Public Law and International Law in Heidelberg on July 11th-12th, 2024.
