Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the court advance within the final deadline.
Extrahierter Entscheid
No. Because the advance was neither paid in cash nor duly evidenced as timely paid, the court had to refuse entry.
Extrahierte Begründung
The appellant ignored the warning attached to the non-extendable grace period under Art. 62(3) BGG; under Art. 108(1)(a) BGG, non-payment leads to non-entry.
