Kernrechtsfrage
Whether the father's conduct amounted to post hoc consent or ratification under Art. 13(1)(a) HEntfÜ.
Extrahierter Entscheid
The father, by his conduct, clearly ratified the child's continued stay in Switzerland; the return exception therefore applied.
Extrahierte Begründung
The court relied on admitted and established facts: the father knew of the Swiss move, visited mother and child, planned a shared future in Switzerland, visited a prospective flat, waived French child allowances, and transported items for the mother's work in Switzerland. These acts, taken together, clearly indicated consent to the child's retention.
