Question juridique clé
Whether the arbitration clause was invalid because it referred to inconsistent arbitration rules and appointing authorities.
Solution extraite
The clause was not wholly invalid; the incompatible appointment mechanism could be disregarded or replaced, while the clear agreement to arbitrate before a Zurich-based institutional tribunal remained effective.
Motifs extraits
The court applied principles of interpretation and favoring effectiveness of arbitration agreements. The parties clearly intended to exclude state courts and submit disputes to arbitration under the Zurich Chamber rules; the conflicting ICC appointment reference created only a partial impossibility, not a total failure of consent.
