Questão jurídica principal
Whether the appeal could proceed despite non-payment of the advance on costs after an unsuccessful legal-aid request.
Decisão extraída
No. Because the advance on costs was not paid within the grace period, the appeal had to be declared inadmissible under Art. 108 BGG.
Fundamentação extraída
The legal-aid request had already been rejected and could not be revisited; the appellant also failed to substantiate his inability to pay. Since the advance was still unpaid after the deadline, non-entry followed as announced.
