Hamburg International Arbitration Days Conference at Bucerius 2023

Arbitration with State-Parties

Salient Issues

Date Tuesday, 28 March 2023  
Time 13:30-18:30  
Venue Bucerius Law School, Helmut Schmidt Auditorium Jungiusstr. 6, 20355 Hamburg  
Fees 30 EUR (Conference); 129 EUR (Conference dinner)  

About the Conference

Arbitration with state-parties involves numerous challenges and conundrums – from the frequently raised immunity issues to procedural, material and practical considerations. While the number of commercial arbitrations with the involvement of state entities has considerably risen, the ongoing energy crisis in Europe may add a number of cases with state-party involvement in the future. 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 immunity, enforcement and more salient topics.

Following the HIAD Conference, we cordially invite all participants to join the speakers for a four-course networking dinner at 20:00. We will meet at Restaurant VLET in the heart of the Speicherstadt, an UNCESCO World Heritage site in Hamburg’s city center. The cover charge (four-course-meal and beverages) amounts to 129 € (incl. VAT).

Guided tour for arbitration practitioners at the Elbphilharmonie followed by refreshments



28 March 2023


Where   Hamburg Elbphilharmonie
Registration     Via email under info(at) 


 FURTHER information


On the occasion of the Hamburg International Arbitration Days (HIAD), the Hamburg Arbitration Circle (HAC) cordially invites international arbitration practitioners to a guided tour at the Elbphilharmonie with refreshments at the Westin Hotel at the end of the tour.

Meet colleagues and gain detailed insights into the extraordinary architecture and musical program of Hamburg’s cultural landmark in the HafenCity, the Elbphilharmonie. The Elbphilharmonie opened its doors for the first time on 11 January 2017. On the banks of the river Elbe, supported by approximately 1,700 reinforced concrete piles, a modern building complex has emerged which contains – in addition to 3 concert halls – a hotel, 45 private apartments and the Plaza, a public viewing area with a 360° view of the city. The centrepiece of the Elbphilharmonie is also currently one of the most exciting structural projects in Europe: a world-class concert hall that is detached from the rest of the building for soundproofing reasons. Situated at a height of 50 metres above ground level in a unique location in Hamburg’s historic port, and with seating for 2,100 people, the Elbphilharmonie is the perfect symbiosis of architecture and music…

The tour will take you around the former warehouse upon which the Elbphilharmonie was built, via the Plaza and through the foyers to the heart of the Elbphilharmonie – the Grand Hall. The tour is followed by a social gathering with refreshments at the Westin Hotel, which is in the same building.

The tour is limited to 30 participants. Please register under info(at)
