Kernrechtsfrage
Whether the appeal was admissible despite the absence of a specific power of attorney authorizing the lawyer to appeal.
Extrahierter Entscheid
The appeal was inadmissible because the required authorization was not produced within the set deadline.
Extrahierte Begründung
Under Art. 40(2) LTF, counsel must prove authority by power of attorney. If it is missing, the Federal Tribunal grants a deadline to cure the defect under Art. 42(5) LTF and warns that the filing will not be considered. The defect was not cured.
