Question juridique clé
Whether the arbitral award had to be set aside for violation of public policy because the tribunal rejected a claim of essential mistake.
Solution extraite
No public policy violation was shown; the arbitral tribunal applied Swiss contract law and relied on Art. 25(1) OR to reject the mistake defense.
Motifs extraits
Public policy review is limited to fundamental legal principles and requires a contradiction in both reasoning and result. The tribunal did not disregard good faith; it found the appellant knew of the relevant relationship and should have investigated further.
