Kernrechtsfrage
Whether the child's habitual residence was New York before the retention in Switzerland.
Extrahierter Entscheid
The child's habitual residence was New York.
Extrahierte Begründung
The child had lived in New York for years, attended kindergarten and school there, and was socially integrated; habitual residence is the child's factual center of life, not the custodial parent's intention.
