Monday, June 26, 2023
Arnold & Porter
Tower 42 25 Old Broad Street
United Kingdom

While many aspects of international arbitration have been the subject of intense debate, ethical issues — those encountered by arbitrators, counsel, and parties, in both commercial and investment arbitration — have received relatively little attention. This prominent panel will explore such ethical issues, including conflicts of interests, privilege rules, and the development of codes of conduct for adjudicators.


Lucas Bastin is a King’s Counsel at Essex Court Chambers. Lucas has extensive experience in international disputes, including very large international commercial and investment arbitrations, arbitration-related court proceedings, and other multi-jurisdictional disputes.

Dr. Conway Blake is a member of the International Dispute Resolution Group at Debevoise & Plimpton, based in London. Conway represents corporate clients, sovereigns, and international organisations on a range of contentious matters, particularly in investor-state arbitration, public international law disputes, and commercial arbitrations governed by various substantive laws and conducted under the major arbitral rules.

Erica Stein is an independent arbitrator acting in international commercial and investment arbitrations. Erica has over 20 years of experience in international arbitration, including, until October 2022, as a partner in the international arbitration group of Dechert LLP. Erica is the co-chair of the IBA Arbitration Guidelines and Rules Subcommittee and, in this capacity, is the co-chair of the IBA Task Force on the Revision of the 2014 Conflicts Guidelines and the IBA Task Force on Privilege in International Arbitration.


Bart Wasiak is a senior associate in the International Arbitration group at Arnold & Porter. Bart's practice focuses on representing sovereign states and private-sector clients in high-stakes international arbitration proceedings.
