Kernrechtsfrage
Whether the Federal Supreme Court could enter into the appeal despite the unpaid advance on costs.
Extrahierter Entscheid
No. Because the advance on costs was not paid within the set deadline and the required proof of timely payment was not submitted, the Court had to refuse entry.
Extrahierte Begründung
The appellant had been warned under Art. 62(3) BGG that failure to pay would lead to non-entry. The conditions for payment were not met within the non-extendable period, so non-entry followed under Art. 108(1)(a) BGG.
