Taking Evidence in International Arbitration
European and (Latin)American Perspectives
HIAD Conference 2025
The 8th HIAD Conference on ‘Taking Evidence in International Arbitration - European and (Latin)American perspectives’ will take place on 8 April 2025. Most cases turn on the facts rather on the law. Thus, the taking of evidence to establish the facts is of crucial importance in many arbitral proceedings. At the same time and despite all harmonization efforts by the IBA, the rules and practices often differ from jurisdiction to jurisdiction. The Center for International Dispute Resolution at Bucerius Law School, CAM-CCBC, HAC and Rechtsstandort Hamburg e.V. cordially invite you to join the debate on some of the salient problems in taking evidence in international arbitration and existing harmonization efforts.
All participants are cordially invited to join the speakers for a networking dinner at La Sala (Bunker Hamburg) at 20:00. The cover charge (food and beverages) amounts to 135 € (incl. VAT). Please register for the dinner on the conference‘s website.
