Key legal question
Whether the appeal could seek substantive findings beyond annulment of the arbitral award
Extracted holding
The Federal Supreme Court could only set aside the award, except on jurisdictional issues; the requests for declarations on the amount owed and no joint liability were inadmissible.
Extracted reasoning
An appeal against an international arbitral award is in principle purely cassatory under Art. 77(2) BGG and Art. 190 IPRG.
