Kernrechtsfrage
Whether the criminal appeal was admissible without a valid written or electronic power of attorney.
Extrahierter Entscheid
No. A representative before the Federal Supreme Court must prove authority by written or electronic power of attorney; otherwise the filing is inadmissible.
Extrahierte Begründung
Art. 40(2) and 42(5) LTF require production of a procuration; the requirement cannot be replaced by other proof. Without a valid mandate, the filing is null and cannot be considered.
