Questão jurídica principal
Whether the civil appeal had to be declared inadmissible for failure to pay the advance of costs within the additional deadline.
Decisão extraída
Yes. Because the advance of costs was not paid within the second, non-extendable deadline, the appeal was inadmissible.
Fundamentação extraída
Under Art. 62(3) BGG, the judge must set a suitable deadline for the advance and, if payment is not made, grant a further deadline; non-payment within that second deadline results in inadmissibility. That situation was met here.
