Key legal question
Whether the federal complaint was admissible in a Hague return case decided by the Zurich High Court as sole cantonal instance
Extracted holding
The complaint in civil matters was admissible; the federal court had jurisdiction and the filing was timely.
Extracted reasoning
Return decisions under the Hague Convention concern mutual legal assistance and enforcement of foreign civil law; the cantonal decision was a final decision of the only cantonal instance, and the ten-day deadline was met.
