Questão jurídica principal
Whether the federal appeal could be entered into despite non-payment of the requested advance costs.
Decisão extraída
No; the appeal could not be examined because the advance costs were neither paid nor credited within the additional time limit.
Fundamentação extraída
Under Art. 48(4) and Art. 62(3) LTF, failure to pay the advance costs within the extended deadline makes the appeal inadmissible.
