Questione giuridica chiave
Whether the appeal against the cantonal decision on an arbitral interim ruling was admissible under Article 93 BGG.
Decisione estratta
The appeal was not admissible because the challenged decision was an interim decision and the appellant showed neither a non-reparable legal prejudice nor that an immediate federal ruling could end the case.
Motivazione estratta
The Federal Supreme Court held that it could not itself issue a final decision on the merits after a successful appeal, because under the national arbitration regime it is bound by the cassatory nature of the nullity complaint. The alleged burden of disclosing business secrets was insufficient, since the appellant did not show that the arbitral procedure could not protect legitimate confidentiality interests.
