Question juridique clé
Whether the Hague Child Abduction Convention applied and the children's retention in Switzerland was wrongful.
Solution extraite
Yes. The children had their habitual residence in Croatia, both parents held joint custody, and the mother exercised custody rights when they were taken to Switzerland.
Motifs extraits
Consent goes to a defence against return, not to the Convention's applicability. The Article 3 criteria were satisfied, so the retention was wrongful.
