The half-day ITA-ASIL Conference is presented annually by the ITA Academic Council with the American Society for International Law (ASIL) immediately preceding the ASIL Annual Meeting. Scholarship is a hallmark of this conference. New voices are reshaping international arbitration practice by adopting innovative reform strategies and upholding evolving values. International, supranational and domestic actors are each playing significant roles as rule-makers, with varying degrees of transparency. Driving forces are sustainability, inclusiveness and regionalism. Sustainability and inclusiveness – including the rebalancing of a range of social and environmental interests will affect international arbitration practice on many levels; one key challenge will be determining how to apply emerging standards in concrete ways and in particular disputes. On regionalism, rulemaking affecting international arbitration practice today, in significant part, is regional rulemaking by international and supranational actors. New voices relying on innovative strategies to uphold evolving values will significantly impact the practice area. Who are the law makers in the new age of arbitration?
