Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the court advance within the fixed grace period.
Extrahierter Entscheid
No. Because the advance was neither paid in cash nor duly evidenced as timely paid, the appeal could not be entered into.
Extrahierte Begründung
The appellant ignored the non-extendable deadline set under Art. 62(3) BGG; therefore, under warning of non-entry, the court had to decline to hear the appeal pursuant to Art. 108(1)(a) BGG.
