Questão jurídica principal
Whether the appeal had to be entered into despite non-payment of the court costs advance.
Decisão extraída
No; because the advance was not paid within the non-extendable deadline, the court had to refuse entry under Art. 108 BGG.
Fundamentação extraída
The appellant ignored the initial payment order and the subsequent final deadline; the later legal-aid request was insufficient because it lacked supporting evidence of financial situation.
