In its decision of 3 June 2020, the international commercial chamber of the Paris Court of Appeals follows the same reasoning of a previous decision rendered by the First Chamber of the Court of Appeals in 2017, but arrives to the conclusion that had been envisaged by the French Supreme Court when setting aside such prior decision of the Court of Appeals in 2019. As a result, the partial award on jurisdiction rendered in an investment arbitration is set-aside. In the meantime, the arbitral tribunal has rendered a final award on the merits. This commentary explores the consequences that the setting aside of the partial award on jurisdiction has on the final award on the merits, in light of the Paris Court of Appeals’ jurisprudence.
