WWL Ranking: Future Leader

WWL says

Gustav Flecke-Giammarco is a firm favourite among sources who note he “knows anything and everything about arbitration” and add he is "incredibly authoritative and effective before arbitral tribunals".


Gustav is a partner at Seven Summits Arbitration (7SA), a Munich-based disputes specialist firm combining 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 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 has extensive experience with ad hoc arbitrations (domestic and UNCITRAL Arbitration Rules), and sits as chair, co-arbitrator, sole arbitrator and emergency arbitrator at various seats throughout Europe. Gustav’s main areas of expertise include construction and engineering, post-M&A, international sales, licensing, distribution, energy (including oil and gas) and infrastructure projects.

Before 7SA, Gustav practised with the litigation and arbitration group of Heuking Kühn Lüer Wojtek in Düsseldorf 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, Gustav supervised over 850 proceedings, including investment treaty and emergency arbitrator cases, and was involved in the scrutiny of 450 awards.

Gustav is a member of the ICC Commission on Arbitration and the editorial board of the Journal of International Arbitration. He has published and lectured widely on ADR related topics. Gustav served on the drafting committee for the 2018 DIS Arbitration Rules and co-edited The DIS Arbitration Rules – An Article-by-Article Commentary, close to 1000 pages of the most comprehensive treatise yet on the DIS Rules.
