Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the court advance.
Extrahierter Entscheid
No. Because the appellant did not pay the ordered advance within the original deadline or the statutory grace period, the Court could not enter into the appeal.
Extrahierte Begründung
The advance-payment order and subsequent grace-period order were duly served; the amount remained unpaid, so non-entry followed under Art. 108 BGG.
