Questão jurídica principal
Whether the criminal appeal is admissible without a power of attorney from the appellant.
Decisão extraída
The appeal is inadmissible because counsel did not produce the required written power of attorney within the set deadline.
Fundamentação extraída
Art. 40(2) and 42(5) LTF require counsel to prove authority by written or electronic power of attorney; failure to cure the defect makes the filing inadmissible.
