Kernrechtsfrage
Whether the appeal was admissible despite the appellant's failure to pay the court advance.
Extrahierter Entscheid
No. Because the appellant neither paid the advance nor showed that the required amount had been debited from its bank or postal account in favor of the Federal Tribunal, the appeal was inadmissible.
Extrahierte Begründung
Art. 48(4) LTF requires proof of debit when payment is not credited in time; absent compliance, Art. 62(3) LTF requires non-entry.
