Questão jurídica principal
Whether the arbitral tribunal violated the appellant's right to be heard.
Decisão extraída
No; the complaint in substance attacked the tribunal's fact-finding and legal assessment, not any denial of the opportunity to present arguments or evidence.
Fundamentação extraída
A hearing-right violation requires a formal denial of justice or omission to consider essential submissions. The award showed no such omission, and the complaint was used improperly to challenge the merits.
