Course Description

The aim of the course is to study the prohibition of the use of force in contemporary international law. Some commentators claim that the field has undergone substantial changes arising especially with the development of the 'war against terror'. Since 9/11, and this would have been confirmed after the Paris events of November 2015, self-defence against non-State actors, pre-emptive self-defence, or humanitarian intervention would have been recognized by the international community. But some other authors disagree with this interpretation of international law, pointing the ambiguity of recent precedents like Ukraine, Yemen or Syria. During this course, we will assess this legal debate by examining relevant texts, case-law and precedents. The course is composed of lectures and discussions about current precedents, especially surrounding the war against ISIS.
