Question juridique clé
Whether the state constitutional complaint against the Zurich return order was admissible despite the later German order.
Solution extraite
The complaint was inadmissible because it relied on a new fact arising after the cantonal decision; no exception to the novum prohibition applied.
Motifs extraits
Federal review is based on the facts found by the cantonal court. A post-decision German order is a true new fact and cannot be introduced in this complaint.
