The second public session of the House of Lords inquiry into artificial intelligence (AI) in weapon systems took place at the end of March. The session examined how the development and deployment of autonomous weapons might impact upon the UK’s foreign policy and its position on the global stage and heard evidence from Yasmin Afina, Research Associate at Chatham House, Vincent Boulanin, Director of Governance of Artificial Intelligence at the Stockholm International Peace Research Institute, and Charles Ovink, Political Affairs Officer at United Nations Office for Disarmament.
Among the wide range of issues covered in the two-hour session was the question of who could be held accountable if human rights abuses were committed by a weapon system acting autonomously. A revealing exchange took place between Lord Houghton, a former Chief of Defence Staff (the most senior officer of the UK’s armed forces), and Charles Ovink. Houghton asked whether it might be possible for an autonomous weapon system to comply with the laws of war under certain circumstances (at 11.11 in the video of the session):
“If that fully autonomous system has been tested and approved in such a way that it doesn’t rely on a black box technology, that constant evaluation has proved that the risk of it non-complying with the parameters of international humanitarian law are accepted, that then there is a delegation effectively from a human to a machine, why is that not then compliant, or why would you say that that should be prohibited?”
This is, of course, a highly loaded question that assumes that a variety of improbable circumstances would apply, and then presents a best-case scenario as the norm. Ovink carefully pointed out that any decision on whether such a system should be prohibited would be for United Nations member states to decide, but that the question posed ‘a big if’, and it was not clear what kind of test environment could mimic a real-life warzone with civilians present and guarantee that the laws of war would be followed. Even if this was the case, there would still need to be a human accountable for any civilian deaths that might occur. Read more
