Kernrechtsfrage
Whether the public law appeal was admissible despite non-payment of the requested advance on costs.
Extrahierter Entscheid
The appeal is inadmissible because the appellant neither paid the requested advance nor filed proof of debit within the extended deadline.
Extrahierte Begründung
After two presidential orders setting a deadline and a non-extendable grace period under Art. 62 LTF, the appellant failed to comply. The consequence expressly announced in the second order applies.
