Kernrechtsfrage
Whether the constitutional complaint was admissible despite the earlier cantonal non-entry decision.
Extrahierter Entscheid
The complaint was inadmissible because the appellant lacked a legally protected interest in having the advance-payment order set aside.
Extrahierte Begründung
The cantonal court had already failed to enter on the underlying appeal for non-payment of the advance, before the federal complaint was filed. Even if the federal court annulled the advance-payment order, the cantonal non-entry decision would remain unaffected.
