Questão jurídica principal
Whether the appeal can be entered into despite non-payment of the court cost advance within the deadline.
Decisão extraída
No. Because the advance was neither paid nor properly proven within the granted grace period, the court refused to hear the appeal.
Fundamentação extraída
Under Art. 62(3) BGG, failure to pay the requested advance of costs after warning leads to non-entry; the same follows here under Art. 108(1)(a) BGG.
