On 8 September 2022, the Vienna Investment Arbitration Debate was held for the fifth time on the top floor of the Juridicum. Dr. Moritz Keller (Clifford Chance) and Prof. Dr. August Reinisch (University of Vienna) chaired the debate. As in previous years, the panelists were assigned a position which did not necessarily correspond to their actual professional opinion, so that they could debate controversial issues of international investment law and investment arbitration irrespective of their actual opinion. To foster an open climate for discussion the debate was held under the Chatham House Rule.

The focus of the panels this year was on "Corruption and other Illegalities" and "Full Protection and Security in Action". The panelists were Prof. Ursula Kriebaum (University of Vienna), Prof. Yarik Kryvoi (British Institute of International and Comparative Law), Jean-Paul Dechamps (Partner & Founder, Dechamps International Law) and Amanda Neil (Special Counsel, Freshfields Bruckhaus Deringer). Following each panel, more than 50 participants in the audience discussed the arguments presented.

The Vienna Investment Arbitration Debate concluded with a keynote speech by John Beechey CBE.
