Key legal question
Whether the complaint against the domestic arbitral award was admissible under the ZPO and BGG framework
Extracted holding
The complaint was not admissible because the appellant did not properly substantiate any cognizable ground under Art. 393 ZPO.
Extracted reasoning
The Court held that only the limited arbitral-review grounds under Art. 393 ZPO were available and that the appellant failed to meet the strict duty of substantiation under Art. 77(3) BGG.
