Questão jurídica principal
Whether the appeal could be entered into despite non-payment of the court advance within the extended deadline.
Decisão extraída
No. Because the advance was still unpaid after the grace period, the appeal could not be heard.
Fundamentação extraída
Under Art. 62(3) BGG, failure to pay the required advance after a final deadline allows non-entry in the simplified procedure under Art. 108(1)(a) and (2) BGG.
