Question juridique clé
Whether the state-law challenge to the international arbitral award was admissible under the PILA exclusion rules.
Solution extraite
The challenge was admissible because the PILA chapter applied and the exclusion of challenge was ineffective against the Swiss-seated respondent.
Motifs extraits
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.
