Question juridique clé
Whether the arbitral award had to be set aside for violation of the right to be heard regarding the addendum and price agreement
Solution extraite
No. The tribunal expressly addressed the appellant's argument and gave alternative reasons, including procedural inconsistency and, in any event, a factual finding of agreement on the price term.
Motifs extraits
The Supreme Court held that the tribunal had not ignored the argument. Complaints about burden of proof, contract interpretation, and evidentiary assessment were merely appellatory and not a valid ground under Art. 190(2) PILA.
