Questione giuridica chiave
Whether the appellant could rely on alleged evidentiary violations despite not exhausting the cantonal appeal path
Decisione estratta
Challenges that could still have been raised before the cantonal cassation court were not admissible before the Federal Supreme Court.
Motivazione estratta
The renewed reasoning of the Handelsgericht after remittal could have been attacked for arbitrariness in fact-finding or cantonal procedural violations, so the appellant had to exhaust that remedy first.
