The purpose of this Round Table is to discuss and clarify current issues regarding the application of international law on weapons and other means of warfare, in light of current technological developments and abusive practices which characterise an increasingly worrying scenario of contemporary armed conflicts. Furthermore, another focus was the issue of the compliance with the States’ international obligations to conduct weapons reviews (as set forth in Article 36 of Additional Protocol I), an obligation which has become more and more relevant particularly in light of the increasing pace of evolving technologies. Conversely, the event reflected largely on best practices in applying IHL to new weapons and new means of warfare in order to respect the prohibition of the use of weapons likely to violate the principle of distinction or to cause superfluous injury or unnecessary suffering. The Round Table gathered together around 200 participants from the different regions of the world including military experts, academics and representatives of governments, international organizations, IHL practitioners and NGOs which spent two to discuss IHL related detention key issues.
