As spheres of authority in the global order increasingly overlap and provoke conflicts between them, this panel explores the ways in which these interface conflicts are dealt with and produce a new order ‘at the margins‘. Interface conflicts arise when actors have conflicting views about international norms and rules associated with international authorities. Actors from different spheres of authority more often than not engage with each other directly, be it in the formal setting of a court or in more informal venues. The papers seek to develop a typology of the norms applied to manage such conflicts (Krisch) and how courts in particular address or avoid them (Birkenkötter). They also investigate the interaction of formal and informal transnational norms in the fields of corporate social responsibility (Reimers) and transnational financial regulation (Corradini). All panelists work together in the interdisciplinary Berlin-based OSAIC research group.
