Kernrechtsfrage
Whether the appeal met the formal requirements of Art. 42 BGG and was therefore admissible
Extrahierter Entscheid
The appeal did not contain any request and did not engage with the cantonal court's reasoning, so it failed the minimum requirements for a valid appeal.
Extrahierte Begründung
Under Art. 42 BGG, the appellant must state requests and reasons showing how the challenged decision violates law. The submission did not address the decisive findings, especially on work capacity and repayment of unlawfully paid benefits.
