Kernrechtsfrage
Whether the federal complaint was admissible despite non-payment of the required cost advance within the set deadline.
Extrahierter Entscheid
The complaint was not admitted because the appellant did not pay or duly prove timely payment of the cost advance within the non-extendable deadline.
Extrahierte Begründung
After unsuccessful reminder under Art. 62 para. 3 BGG, the appellant neither paid cash nor deposited the amount at a post office for the Federal Supreme Court, nor submitted the required confirmation of debit in time; therefore non-entry under Art. 108 para. 1 lit. a BGG followed.
