Questão jurídica principal
Whether the appeal could be entered into despite non-payment of the court cost advance.
Decisão extraída
No. Because the appellant did not pay the advance even within the additional deadline, the Federal Supreme Court declined to enter into the appeal.
Fundamentação extraída
Under Art. 62 para. 1 and 3 BGG, a cost advance must be paid; if the extended deadline expires unused, the court does not enter into the filing.
