Whether the appeal was admissible despite non-payment of the court-ordered advance on costs
Decisione estratta
No. Because the advance on costs was not paid within the extended deadline, the appeal was inadmissible.
Motivazione estratta
The advance on costs was neither paid nor credited, and no proof of payment was received. Under the Federal Supreme Court Act, failure to pay the advance within the time limit leads to inadmissibility.
