More than a decade after the emergence of public law approaches to international institutions, such as Global Administrative Law, Global Constitutionalism, or International Public Authority, the international order has changed dramatically.

The panel will discuss how the authoritarian, nationalist pushback affects the problem-solving capacity and the legitimacy of international institutions and courts as well as their resilience.
