Questão jurídica principal
Whether the federal appeal was admissible despite non-payment of the requested advance on costs.
Decisão extraída
The appeal was inadmissible because the appellant did not pay the advance on costs within the deadlines set, including the extended deadline.
Fundamentação extraída
Under Art. 62 para. 3 LTF, failure to pay the advance on costs within the allotted time leads to inadmissibility; the court therefore applied Art. 108 para. 1 let. a LTF.
