Questão jurídica principal
Whether the appeal should be entered into despite non-payment of the court advance within the deadline.
Decisão extraída
No. The appellant failed to pay the full advance, did not show unforeseeable impediments, and did not submit a properly substantiated legal-aid request.
Fundamentação extraída
Under Art. 62 BGG, a party must pay the advance; if the advance is not paid within the set and extended time limit, the court must not enter into the appeal. No further extension of a grace period is available absent special unforeseeable reasons specifically substantiated, and the appellant provided neither payment nor a valid legal-aid application.
