Questione giuridica chiave
Whether the cantonal court violated the right to be heard by giving insufficient reasons on the arbitral award and its review.
Decisione estratta
No. The cantonal court's brief reasoning was sufficient given the limited nullity review under the concordat.
Motivazione estratta
The court only had to assess whether the award was manifestly contrary to the file or evidently unlawful/unfair; it could therefore adopt a concise reasoning and need not address every argument.
