Kernrechtsfrage
Whether the constitutional complaint against the Administrative Court's refusal to hear the appeal was admissible despite the contested decision being a preliminary one.
Extrahierter Entscheid
The complaint was inadmissible insofar as it challenged the court's reliance on subsidiarity of the supervisory complaint, because no irreparable legal harm existed; however, the court's separate view on functional competence could not be reviewed because it was not specifically challenged.
Extrahierte Begründung
A preliminary decision is only reviewable if it can cause irreparable legal harm. That was absent because later ordinary or constitutional remedies remained available depending on the future course of proceedings.
