Kernrechtsfrage
Whether the constitutional subsidiary appeal was admissible after the appellant failed to pay the advance of costs within the grace period.
Extrahierter Entscheid
The appeal was inadmissible because the advance of costs was not paid within the non-extendable additional deadline.
Extrahierte Begründung
Under Art. 62(3) LTF, non-payment within the second deadline makes the appeal inadmissible; the request for a new deadline was not admissible, and any restitution request would lack sufficient reasoning.
