Key legal question
Whether the civil law appeal against the international arbitral award was admissible and what review standard applied.
Extracted holding
The appeal was admissible only within the narrow grounds of Arts. 190-192 PILA; the Federal Supreme Court was bound by the arbitral findings and could only review clearly and properly reasoned complaints.
Extracted reasoning
International arbitration appeals are cassatory; new documents and factual challenges to proof assessment are inadmissible; the court reviews only substantiated grounds under Art. 77(3) LTF and Art. 106(2) LTF.
