Kernrechtsfrage
Whether the state-law challenge to the international arbitral award was admissible under the PILA exclusion rules.
Extrahierter Entscheid
The challenge was admissible because the PILA chapter applied and the exclusion of challenge was ineffective against the Swiss-seated respondent.
Extrahierte Begründung
The parties had not validly excluded Chapter 12 PILA; the respondent's seat in Switzerland made an exclusion under Art. 192 PILA ineffective, and the award's declaration of finality was not a sufficient waiver.
