Question juridique clé
Whether the appeal could be heard on factual and procedural complaints already decided by the cantonal cassation court
Solution extraite
Those complaints were inadmissible because the appellant attacked the wrong decision; only legal issues against the Handelsgericht could be reviewed.
Motifs extraits
Factual findings and alleged procedural violations had to be challenged before the cantonal cassation court; the federal appeal did not engage with that court's reasoning.
