Kernrechtsfrage
Whether the appeal was admissible against the Handelsgericht's partial judgment that had already been annulled by the cantonal cassation court
Extrahierter Entscheid
No. Once the partial judgment had been annulled as a whole, it no longer existed as an object of challenge before the Federal Supreme Court.
Extrahierte Begründung
The annulled judgment could not be attacked again; any prior reasoning left in place by the cassation court did not preserve the judgment as a reviewable object.
