Kernrechtsfrage
Whether the federal complaint was admissible despite the appellant not challenging the failure to pay the required cost advance.
Extrahierter Entscheid
The complaint cannot be examined because the appellant does not engage with the decisive ground of the cantonal non-entry decision.
Extrahierte Begründung
Under Art. 108 BGG, submissions that do not address the reasoning of the challenged decision are not entered into. The federal filing said nothing about the non-payment of the requested advance.
