Kernrechtsfrage
Whether the reform appeal was admissible when the appellant challenged only one of two independent grounds for abusive dismissal.
Extrahierter Entscheid
The appeal was inadmissible because the appellant failed to attack the alternative ground that the dismissal was retaliatory under Art. 336(1)(d) CO.
Extrahierte Begründung
Where a cantonal decision rests on several independent sufficient reasons, each must be specifically contested; otherwise the judgment stands on the unchallenged basis.
