Key legal question
Whether the child's removal was wrongful and whether return must be ordered under the Hague Child Abduction Convention.
Extracted holding
The removal was wrongful, but return could not be decided without first checking whether the child would remain with the mother in France pending the custody proceedings.
Extracted reasoning
The child was very young and always cared for by the mother; separation from her would be intolerable. The cantonal court had to obtain French assurances that the mother could keep the child until the merits custody decision.
