Questão jurídica principal
Whether the revision request was admissible based on the claim that a later private accounting report revealed new, relevant facts or conclusive evidence under Art. 396 al. 1 let. a CPC.
Decisão extraída
No. The report only reinterpreted pre-existing accounting documents and did not reveal facts that were unknown or unavailable in the prior arbitration; X also failed to show due diligence.
Fundamentação extraída
Revision under Art. 396 CPC requires pre-existing but previously uninvoicable facts or evidence. A later expert opinion based on the same documents cannot replace the arbitral tribunal's appreciation of evidence unless it uncovers genuinely new factual elements. Here the tribunal and experts had already addressed the contested accounting issues.
