Disclosure in Antitrust Damages Actions in Europe

On 3rd November 2023, the University of Vienna, Department of European, International and Comparative Law, together with the The European Circle for Competition Damages and the Austrian Society for European Law (ÖGER) hosted a one-day conference on the topic: “Disclosure in Antitrust Damages Actions in Europe”.

Access to evidence has been marked as the key issue in antitrust damages actions in the 2014 EU Damages Directive. Roughly ten years after the Damages Directive and a first wave of cases on national level, we looked at the implementation of the disclosure rules throughout Europe. In three panels, we discussed pressing issues, such as the CJEU case law, perspectives of national courts (Austria, Germany, Spain, Netherlands, Norway, Portugal, and UK), cooperation with competition authorities, confidentiality arrangements, disclosure and economic evidence proceedings, cost of disclosure, and much more.

Invited speakers included: Georg Kodek (OGH/WU - Vienna University of Economics and Business), Vivien Terrien (Court of Justice of the European Union), Hanno Wollmann (Schönherr/Universität Wien), Verena Strasser (Bundeskartellanwalt-Stellvertreterin), Florian Neumayr (bpv Huegel), Petra Leupold (Verein für Konsumenteninformation), Peter Gussone (GQL), Julia Suderow (Suderow Fernández Abogadas), Joost Möhlmann (Van Benthem & Keulen), Miguel Sousa Ferro (Sousa Ferro & Associados), Clemens Kerle (CMS), Ben Lasserson (Mishcon de Reya LLP), Martin Seegers (CDC Cartel Damage Claims), Martin Gassler (Wolf Theiss), and Lena Hornkohl (University of Vienna).
