Questão jurídica principal
Whether the appeal should be entered into despite non-payment of the advance on costs within the additional deadline.
Decisão extraída
No. Because the advance on costs was not paid within the non-extendable grace period, the appeal could not be considered.
Fundamentação extraída
Under Art. 62 para. 1 and 3 BGG, failure to pay the required advance even within the grace period entails non-entry; the simplified procedure of Art. 108 BGG applies.
