Kernrechtsfrage
Whether the federal appeal met the formal requirements of Art. 42 BGG and could be examined on the merits.
Extrahierter Entscheid
The filing did not contain a clear request or a sufficient reasoning directed against the decisive grounds of the cantonal judgment; the defect was not cured in time, so the appeal was not entered into.
Extrahierte Begründung
Under Art. 42 BGG, an appeal must contain requests and a reasoned explanation showing how the challenged decision violates law. The appellant did not address the cantonal court's key finding that unemployment benefits were refused because the self-employed activity was not contributory employment under Art. 13 f. AVIG. References to IV measures were irrelevant.
