Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the advance costs within the set deadline.
Extrahierter Entscheid
No. Because the appellant did not pay the advance costs even within the extended deadline, the Federal Supreme Court could not consider the appeal.
Extrahierte Begründung
Under Art. 62 para. 3 BGG, failure to pay the requested advance costs within the deadline permits non-entry; the later submission did not cure the default.
