Questione giuridica chiave
Whether the arbitral tribunal was validly constituted and had jurisdiction over appellants 2-4
Decisione estratta
The tribunal was not duly appointed vis-à-vis appellants 2-4 because arbitration had not been properly initiated against them and their silence could not amount to acceptance of the arbitrator.
Motivazione estratta
The clause required each opposing party to be proposed an arbitrator and then to have the opportunity to propose another. The seller never served appellants 2-4 with the claim or an arbitrator proposal; the arbitrator merely invited them to comment on the merits. Therefore the proceeding never became pending against them and no valid appointment resulted.
