Kernrechtsfrage
Whether the appeal could be considered despite the absence of a power of attorney for the lawyer
Extrahierter Entscheid
The appeal could not be considered because the lawyer did not produce the required authorization within the set time limit.
Extrahierte Begründung
Under Art. 40(2) LTF, representatives must prove their authority by power of attorney. If it is missing, the court fixes a deadline under Art. 42(5) LTF; expiry of that deadline without compliance makes the filing inadmissible.
