Franco Ferrari has just published a paper entitled “National International Commercial Arbitration” in 32 American Review of International Arbitration 439 (2022). In the paper, Professor Ferrari elaborates on the view, expressed in earlier papers (including in Plures Leges Faciunt Arbitrum, 37 Arbitration International 579 (2021) – available here: https://academic.oup.com/arbitration/article/37/3/579/6246135?login=true; Lex Facit Arbitrum 2.0, Diritto del commercio internazionale 915 (2021)) that it is national law that confers juridicity to arbitration, i.e., “where the source of [the arbitrators’] power and the legal nature of the process and of the ensuing decision stem from” (Gaillard). This new paper, which is a review article of International Commercial Arbitration. A Handbook edited by Stephan Balthasar, relies on the Handbook’s various chapters (addressing the New York Convention as well as arbitration law in Austria, Belgium, Brazil, China, England and Wales, France, Germany, Hong Kong, India, the Netherlands, the Russian Federation, Singapore, Spain, Sweden, Switzerland, and the United States) to corroborate the findings of the earlier papers. At the same time, it allows the reader to identify the many areas in which national law is relevant in the international commercial arbitration context.
