Kernrechtsfrage
Whether the public-law appeal was admissible against the cantonal incidental decision refusing annulment of the first-instance proceedings.
Extrahierter Entscheid
The appeal was inadmissible because the challenged ruling was neither a final decision nor a separately appealable decision on competence or recusal, and no irreparable legal prejudice was shown.
Extrahierte Begründung
Under Arts. 86 and 87 OJ, incidental decisions are immediately challengeable only in limited cases. The refusal to annul the first-instance proceedings did not end the appeal proceedings. Any defect could still be raised later against a final decision, so no irreparable harm existed.
