Kernrechtsfrage
Whether the challenge to the cantonal court's subject-matter competence and alleged hearing violation could be raised only at federal stage.
Extrahierter Entscheid
The competence objection was forfeited because the appellant had itself initiated and pursued the cantonal proceedings without reservation and never challenged the earlier non-entry ruling.
Extrahierte Begründung
Questions of court organization must be raised at the earliest possible stage; by proceeding without reservation the appellant acted contrary to good faith, so the objection was abusive and waived. No separate hearing violation arose because the competence issue was already known and the appellant had no duty to be specially invited on that point.
