Kernrechtsfrage
Whether the constitutional complaint was admissible despite non-payment of the advance on time.
Extrahierter Entscheid
No. The complaint could not be admitted because the advance was neither paid nor properly evidenced within the deadline and grace period.
Extrahierte Begründung
After the warning under Art. 62(3) BGG, the appellant still did not pay the CHF 100 advance at the Federal Supreme Court cashier, did not hand it over at a post office for the court's benefit, and did not provide proof of a timely debit in case of a payment order.
