Kernrechtsfrage
Whether the constitutional complaint could challenge the custody allocation and alleged unequal application of law.
Extrahierter Entscheid
The complaint was inadmissible to the extent it merely reargued federal-law custody criteria; review of custody allocation belonged to federal appeal, not constitutional complaint.
Extrahierte Begründung
The custody question was governed by federal law, so alleged misapplication of Art. 133 ZGB and related criteria could not be raised via constitutional complaint. Only clearly substantiated constitutional grievances were reviewable.
