Question juridique clé
Whether the arbitral award could be challenged for arbitrariness based on alleged insufficient proof of fraud and error.
Solution extraite
The challenge was inadmissible to the extent it merely attacked the arbitral assessment of evidence; arbitrariness under Art. 393 lit. e CPC does not permit a free review of proof appreciation.
Motifs extraits
The complaint targeted witness credibility and the tribunal's evidentiary assessment. The Federal Court held that only manifest contradictions with the record are reviewable, not the tribunal's weighing of evidence or choice between plausible versions.
