Is there any advantage to choosing Paris as the place of arbitration for an ICSID or other arbitration between a State and a private party?

Yes. Paris is recognized for its specific advantages as a seat for both commercial and treaty arbitrations between private entities and States or state entities. Sovereign states and private enterprises both recognize Paris as a neutral and sophisticated forum. Treaty disputes brought before the International Centre for the Settlement of Investment Disputes (ICSID) are often held in Paris, with hearings at the European Headquarters of the World Bank – although the legal importance of the place of the arbitration is very different in ICSID cases as compared to other arbitrations. Treaty and commercial disputes involving states are also frequently submitted to International Chamber of Commerce (ICC) or other institutional arbitration. These arbitrations, in which the legal role of the seat maintains its full importance, are often seated in Paris.
