About the Research Group

The Research Group examines the authority of state, intergovernmental and non-state actors in international institutions: Which actors (states, companies, NGOs, national human rights institutes, cities, etc.) have which form of authority - and how can their authority be democratically embedded?  The empirical focus lies on the United Nations and the European Union. Operationalizing authority with the triad of power, legitimacy and reference to public interests, the Research Group will identify different forms of authority along the lines of institutionalization, legalization and participation.These require and enable the concept of authority to be multiplied between and beyond public and private authority, in order to develop requirements for democracy and international human rights.
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.
