Questione giuridica chiave
Whether the appeal was admissible despite non-payment of the required cost advance within the grace period.
Decisione estratta
No. Because the appellant did not pay the advance in time or prove timely payment by bank/postal debit confirmation, the court had to refuse entry.
Motivazione estratta
After warning under Art. 62(3) BGG, the appellant neither paid the advance in cash nor deposited it at a post office for the federal court, and no proof of timely debit was filed. Under Art. 62(3) and Art. 108(1)(a) BGG, this led to non-entry.
