Research Project at the Centre

International Litigation as a Factor Affecting Negotiation Processes in Militarised Conflicts

This research project intends to enhance understanding of the role of international litigation during major inter-state conflicts. More specifically, the focus is on a setting that presents particular challenges for global governance, viz. governance in the field of international security. Moreover, the inquiry analyses a type of non-State actor (international courts or tribunals) that is meant to be impartial, independent and empowered to take binding decisions – but whose relevance, precisely because of their potentially intrusive influence, has traditionally been limited in security-related disputes. The proposed research queries whether the traditional assessment needs to be revisited as courts and tribunals now ostensibly play a more relevant role in global (security) governance.
