Questão jurídica principal
Whether the recourse against the internal arbitration award was admissible in view of the limited grounds under CPC and LTF.
Decisão extraída
The appeal was inadmissible because the appellant relied on general federal-law violations and appellatory criticism instead of one of the exclusive grounds for setting aside an internal arbitration award.
Fundamentação extraída
For internal arbitration, the Federal Supreme Court may only examine the limited grounds under Art. 393 CPC, and the appeal must be strictly reasoned. The appellant argued as if challenging a cantonal judgment on federal-law grounds, which is excluded by Art. 77 LTF.
