Kernrechtsfrage
Whether the cantonal refusal to hear the defendant's appeal for lack of irreparable harm could be treated as void because the district judge's incidental decision was allegedly void.
Extrahierter Entscheid
No. Nullity of the incidental decision was not shown, and no basis existed to extend any alleged nullity to the cantonal inadmissibility ruling.
Extrahierte Begründung
Nullity of procedural decisions is exceptional; even if the district judge's ruling were erroneous, it was not shown to be null and void. The appellate inadmissibility decision was separately motivated by the absence of irreparable harm.
