Kernrechtsfrage
Whether the appeal was admissible despite the cantonal decision resting on multiple independent grounds
Extrahierter Entscheid
No. Because the appellant challenged only the timeliness ground and did not address the other independent grounds, the appeal had to be declared inadmissible in simplified proceedings.
Extrahierte Begründung
When a decision is based on several independent reasons, the appellant must show that each reason violates the law; otherwise the appeal is inadmissible under simplified procedure.
