Hannes Snellman successfully represented Outokumpu Corporation in an international ICC arbitration between Fennovoima Oy and Rosatom entities where RAOS Project Oy sought to join Outokumpu in 2023. The Arbitral Tribunal accepted Outokumpu’s position denying jurisdiction over Outokumpu and ending the arbitration with respect to Outokumpu.
In January 2023, RAOS Project filed a request to join Outokumpu in existing ICC arbitration proceedings, which related to the termination of the engineering, procurement, and construction (EPC) contract between Fennovoima and RAOS Project regarding the Hanhikivi nuclear power plant. In February 2025, the Arbitral Tribunal confirmed that it did not have jurisdiction to adjudicate the claims brought by RAOS Project and JSC Rusatom Energy International (JSC REIN) against Outokumpu.
