WWL says

Gustav Flecke-Giammarco is “an extremely well-prepared counsel and arbitrator” who stands out for “his unrivalled insight and knowledge of ICC arbitration”.


Gustav Flecke-Giammarco is a partner at Seven Summits Arbitration (7SA), a Munich-based disputes specialist firm dedicated to arbitration. 7SA combines the expertise and cross-border track-record clients expect from a leading international law firm with the flexibility and efficiency of a boutique practice.

Gustav regularly acts as counsel and arbitrator in multifaceted domestic and international arbitrations, involving a wide array of matters under many different laws. His institutional track record includes cases under the ICC, DIS, VIAC, SCC, FAI and SCAI Rules. He also has extensive experience with ad hoc arbitrations (domestic and UNCITRAL Arbitration Rules), and sits as chairman, co-arbitrator and sole arbitrator at various seats throughout Europe. Gustav’s main areas of expertise include construction and engineering, post-M&A, international sales, distribution, energy (including oil and gas) and infrastructure projects.

Before co-founding 7SA, Gustav practised with the litigation and arbitration group of Heuking Kühn Lüer Wojtek in Düsseldorf (2015-2017) and headed the case management team responsible for arbitrations seated in Germany, Switzerland, Austria, Benelux and the Nordic countries at the ICC International Court of Arbitration in Paris. During his tenure at the ICC Secretariat (2009-2015), Gustav supervised over 850 proceedings, including investment treaty and emergency arbitrator cases, and was involved in the scrutiny of some 450 awards.

Gustav is a member of the 2018 DIS Rules drafting committee and the ICC Commission on Arbitration and ADR. He also is a member of the editorial board of the Journal of International Arbitration. Gustav regularly publishes and speaks on arbitration related topics, and teaches arbitration at the University Roma Tre, the Swiss Arbitration Academy and the Swiss International Law School.
