Questão jurídica principal
Whether the appeal was admissible despite not challenging the commercial court's alternative ground
Decisão extraída
No. Because the cantonal judgment rested on two independent grounds and the appellant attacked only one of them, the judgment remained upheld on the unchallenged ground.
Fundamentação extraída
A party must attack all independent grounds supporting the operative result. Since the alternative ground was based on cantonal procedural law and required a different remedy, the civil appeal could not succeed.
