Kernrechtsfrage
Whether the federal complaint was admissible despite the appellant's allegation that the cantonal decision was null and void.
Extrahierter Entscheid
No admissible nullity ground was substantiated; the complaint could not be entered into.
Extrahierte Begründung
The appellant merely invoked nullity without any concrete substantiation. No nullity ground was apparent to the cantonal authority or the Federal Supreme Court.
