Kernrechtsfrage
Whether the federal complaint had to be entered into despite non-payment of the advance on costs.
Extrahierter Entscheid
No; because the appellant did not pay the CHF 7,000 advance within the extended deadline and did not prove timely payment, the court had to issue a non-entry decision.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the advance within the set time limit after warning leads to non-entry under Art. 108(1)(a) BGG.
