Closing Keynote: Arbitration and Armed Conflict

Описание: On, 20 June, Suzanne Spears delivered the closing keynote address of the 2025 London Summer Arbitration School. The lecture addressed Arbitration and Armed Conflict.  Below is a video recording and a short summary of the lecture. 

We live in an era in which the number of armed conflicts globally has reached the highest level since World War II, disrupting international trade, investment, and commerce, and leading to disputes subject to international arbitration. Investor-State dispute settlement (ISDS) increasingly involves wartime expropriation, asset destruction, state contract breaches, and emergency measures, raising issues related to protection and security standards, war clauses, national security, and the doctrine of necessity. This also raises questions about whether arbitral tribunals can consider the laws of war in ISDS cases.

Armed conflict also affects international commercial arbitration, with concepts like force majeure, frustration, and coercion increasingly tested in cases involving business disruptions. Arbitrators also may be asked to address issues under the laws of war in commercial arbitrations.

This keynote address examined the broader implications of armed conflict for ISDS and international commercial arbitration, including whether the threat of arbitration influences the likelihood of conflict or behaviour during conflict, and how tribunals balance investment protection and contract performance with the demands of war. Finally, it will consider the impact of armed conflict on the validity and enforceability of agreements and arbitral awards.
