The challenges taken up in the other research lines necessitate a re-thinking of fundamental principles that underpin the organization of political systems. This becomes especially urgent in view of the rise of populism and authoritarianism. This research line feeds the others through a conceptual, theoretical as well as empirical examination of:
- questions of legitimacy and related principles of democracy, legality, subsidiarity and trust,
- questions of the limitation of power and related principles of the rule of law, the separation of powers, institutional balance, legal certainty, and fundamental rights.
