Kernrechtsfrage
Whether the appeal was admissible despite non-payment of the court advance within the set deadline.
Extrahierter Entscheid
The appeal was inadmissible because the appellant neither paid the required advance nor produced proof that the amount had been debited from its postal or bank account in favor of the Federal Tribunal.
Extrahierte Begründung
Under Art. 48(4) LTF, payment had to be made or proven by debit attestation; absent compliance, the appeal had to be declared inadmissible under Art. 62(3) LTF.
