Questão jurídica principal
Whether the appeal had to be entered into despite the unpaid advance costs.
Decisão extraída
No. Because the appellant did not pay the advance costs within the non-extendable grace period and did not prove timely payment by debit confirmation, the appeal could not be considered.
Fundamentação extraída
After a warning under Art. 62(3) BGG, non-payment of the advance costs within the final deadline requires non-entry under Art. 108(1)(a) BGG.
