Kernrechtsfrage
Whether the appeal was admissible despite the missing handwritten signature.
Extrahierter Entscheid
No. The defect was not cured within the court-prescribed deadline, so the appeal could not be examined.
Extrahierte Begründung
The appellant was warned under Art. 42(5) BGG to remedy the lack of signature by the deadline. He received the warning but did not respond or cure the defect.
