Kernrechtsfrage
Whether the constitutional complaint was admissible despite non-payment of the required advance costs.
Extrahierter Entscheid
The complaint could not be entered into because the advance costs were not paid or duly evidenced within the grace period.
Extrahierte Begründung
After expiry of the non-extendable grace period, the appellant neither paid the CHF 2,000 advance nor provided the required debit confirmation; non-entry followed under Art. 62(3) BGG in conjunction with Art. 108(1)(a) BGG.
