Questione giuridica chiave
Whether the appeal was admissible despite non-payment of the required advance on costs.
Decisione estratta
No. The appellant neither paid the advance nor showed that the amount had been debited in favor of the Federal Supreme Court within the required time.
Motivazione estratta
Under Art. 48(4) LTF, payment must be evidenced; failure to do so leads to non-compliance with the advance-order under Art. 62(3) LTF.
