Self-defence in the Fight against Terrorism: The Enlargement of the Right of Self-defence

Self-defence in the Fight against Terrorism: The Enlargement of the Right of Self-defence

This is a past event

Since the 9/11 terrorist attacks, the right of self-defence has been particularly impacted by “hyperterrorism”. The use of force in the fight against terrorism is one of the thorniest questions in public international law, precisely jus ad bellum which is dedicated to the study of the legal foundations of recourse to armed force. The main purpose of this seminar is first of all to understand the classical requirements for the resort to the right of self-defence and see how those requirements could have evolved as regard to several particularities of terrorist groups (which are different actors than States) and terrorism. The question of different forms of self-defence in reaction to a threat of aggression (anticipatory, pre- emptive, preventive self-defence) will be dealt with as well as the question of the possible use of armed force against non-state actors.
