Questione giuridica chiave
Whether the appeal could be entered into despite defective signature and missing power of attorney.
Decisione estratta
No. The appellant was duly invited to cure the irregularities, but the extended time limit could not be prolonged again and the alleged impediment was not proven.
Motivazione estratta
Under Art. 42(5) LTF, missing signature or authorization must be cured within an appropriate time limit, failing which the filing is not considered. The second extension requested was not available, and the justification for further delay was unsubstantiated.
