Questão jurídica principal
Whether the appeal must be declared inadmissible because the power of attorney for counsel was not produced despite a warning and deadline.
Decisão extraída
Yes. The appeal was inadmissible under Art. 42 para. 5 LTF because the irregularity was not cured and no further time limit is required.
Fundamentação extraída
The appellant was invited to file the power of attorney by 6 October 2010 and expressly warned of the consequences. He did not respond. Unlike the advance-payment situation, the law does not provide an additional grace period to remedy this defect.
