Questão jurídica principal
Whether the appeal should be admitted despite non-payment of the court cost advance
Decisão extraída
No. Because the advance was not paid within the original and extended deadlines, the appeal had to be declared inadmissible in simplified proceedings.
Fundamentação extraída
The notices requesting payment were deemed served under Art. 44(2) BGG; after the deadline expired without payment, Art. 62(3) BGG required non-entry, and the case was manifestly inadmissible under Art. 108 BGG.
