Kernrechtsfrage
Whether the constitutional complaint was admissible despite subsidiarity in view of the pending intermediate dispute under FamFG and ZPO
Extrahierter Entscheid
The complaint was not admitted because the complainants must first await the final conclusion of the intermediate dispute before seeking constitutional review.
Extrahierte Begründung
The subsidiarity of the constitutional complaint requires exhaustion of the ordinary procedural path. A later constitutional complaint remains possible after the legally binding conclusion of the intermediate dispute.
