Kernrechtsfrage
Whether the constitutional complaint had to be entered into despite non-payment of the advance on costs.
Extrahierter Entscheid
No. The complaint was not entered into because the appellant failed to pay the advance even within the extended deadline and did not prove timely payment.
Extrahierte Begründung
After warning, failure to pay the required advance on costs within the deadline set under Art. 62(3) BGG requires non-entry under Art. 108(1)(a) BGG.
