Questão jurídica principal
Whether the appeal against the cantonal decision on annulment of the arbitral partial award was admissible as a partial decision.
Decisão extraída
The cantonal decision was a partial decision under Art. 91(a) LTF because it definitively rejected all counterclaims concerning invalidation of the settlement and accounting.
Fundamentação extraída
Although the arbitration continued on the merits, the partial award materialy disposed of the appellant's invalidation and accounting claims; therefore immediate federal review was possible.
