Questão jurídica principal
Whether the appeal had to be dismissed as inadmissible for failure to pay the cost advance within the extended deadline.
Decisão extraída
Yes. Because the appellant did not pay the advance by the set deadline, the appeal was declared inadmissible under the simplified procedure.
Fundamentação extraída
The court considered the lack of payment decisive. Whether the appellant had opened the returned judicial envelope was irrelevant. Under Art. 108(1)(a) LTF and Art. 62(3) LTF, non-payment after warning requires inadmissibility.
