Questão jurídica principal
Whether the appeal is admissible despite non-payment of the court advance within the deadline.
Decisão extraída
The appeal could not be entered because the required advance was not paid or duly evidenced within the non-extendable time limit.
Fundamentação extraída
Under Art. 62(3) BGG, failure to pay the advance after warning leads to non-entry under Art. 108(1)(a) BGG; the later request for legal aid did not cure the default because it was filed after expiry of the deadline.
