Questão jurídica principal
Whether the appeal could be entered into despite non-payment of the advance fee
Decisão extraída
No. Because the appellant did not pay the required advance fee within the extended deadline under Art. 62 para. 3 BGG, the court could not enter into the appeal.
Fundamentação extraída
The advance payment remained unpaid even after the grace period; under Art. 62 para. 3 BGG this leads to non-entry.
