Kernrechtsfrage
Whether the constitutional complaint was admissible with respect to the alleged violation of Art. 29 para. 1 BV
Extrahierter Entscheid
The complaint was inadmissible insofar as it invoked Art. 29 para. 1 BV, because the appellants did not substantiate that ground independently.
Extrahierte Begründung
The arguments addressed only arbitrary application of Art. 71 ZGB and did not show a separate procedural violation.
