Silje Aambø Langvatn is a postdoctoral fellow in political philosophy at PluriCourts – Centre for the Study of the Legitimate Roles of the International Judiciary (University of Oslo), and affiliated with CSMN.


The focus of Silje’s current research is on conceptions of “legitimacy”, and how legitimacy is distinct from, but also connected to ideas like morality, justice, legality, social acceptance etc. In particular, she discusses legitimacy in relation to international courts, and whether ideas of public justification and public reason can supplement the current dominant conceptions of legitimacy for this type of entity.
