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).


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.
