Questão jurídica principal
Whether the federal appeal could be entered into despite the unpaid cost advance.
Decisão extraída
No. Because the appellant neither paid the advance within the deadline nor proved timely debiting in the event of a payment order, the appeal had to be dismissed without entry.
Fundamentação extraída
After a warned non-extendable grace period under Art. 62(3) BGG, failure to provide the advance triggers non-entry under Art. 108(1)(a) BGG, regardless of further submissions that did not request extension or legal aid.
