Kernrechtsfrage
Whether the appeal met the formal requirements of Art. 42 BGG and could be examined on the merits.
Extrahierter Entscheid
No. The appeal did not sufficiently engage with the reasoning of the cantonal judgment and therefore was not a valid legal remedy.
Extrahierte Begründung
The appellant failed to specify concretely how the cantonal court violated federal law or incorrectly established the facts, despite a prior warning and opportunity to cure within the appeal period.
