Questione giuridica chiave
Whether the federal appeal was admissible despite non-payment of the court advance within the set deadlines.
Decisione estratta
The appeal was inadmissible because the advance of costs was not paid in time and no timely bank or postal debit confirmation was produced.
Motivazione estratta
After the first deadline expired, a non-extendable additional deadline also passed without payment. Under the Federal Supreme Court Act, failure to comply with the advance-of-costs order made the appeal inadmissible, and the manifest inadmissibility justified simplified procedure.
