Kernrechtsfrage
Whether the constitutional complaint was admissible despite non-payment of the court cost advance within the grace period.
Extrahierter Entscheid
The complaint was not entered upon because the required advance costs were not paid or duly evidenced within the non-extendable deadline.
Extrahierte Begründung
After service of the order under Art. 62(3) BGG, the appellant neither paid the CHF 800 advance in cash, nor deposited it at a post office for the Federal Court, nor provided the required proof of timely debit from a Swiss postal or bank account. Under Art. 62(3) BGG, in conjunction with Art. 117 BGG and Art. 108(1)(a) BGG, this led to non-entry.
