Questão jurídica principal
Whether the arbitral tribunal violated the appellant's right to be heard by ignoring the alleged 30% retainage on payment estimate no. 3.
Decisão extraída
Yes. The tribunal failed to address an important argument relevant to damages and did not satisfy its minimum duty to examine the pertinent issues.
Fundamentação extraída
The award and the addendum did not answer the retainage objection, and the tribunal's later reference to accounting records did not resolve the specific complaint that only 70% had been paid.
