Kernrechtsfrage
Whether the appeal against the return order was admissible and whether the Federal Supreme Court could review the case freely on the Convention issues.
Extrahierter Entscheid
The appeal was admissible in principle; the Court reviewed the Hague Convention issues with full cognizance but was bound by the factual findings absent qualified challenge.
Extrahierte Begründung
The case concerned a return decision under the Hague Child Abduction Convention, decided by a single cantonal instance; the 10-day deadline was met. New facts and evidence were inadmissible unless caused by the lower-court decision, which was not shown.
