Kernrechtsfrage
Whether the appeal against enforcement of the child return order was still justiciable after the return had been executed.
Extrahierter Entscheid
The appeal had become moot because the return order was already enforced when the father departed with the child to the United States.
Extrahierte Begründung
Once the federal return decision was carried out, there was no longer any live dispute about suspending its enforcement, so the proceedings had to be discontinued as moot.
