Question juridique clé
Whether the state-law complaint against enforcement of the child return order was admissible insofar as it challenged the merits of the Hague Convention return decision.
Solution extraite
The complaint was not entered into to the extent it attacked the substantive application of the Hague Convention; only enforcement obstacles could be reviewed.
Motifs extraits
Enforcement of a return order under the Hague Convention is governed outside the Convention itself. The enforcement proceeding may not reopen the return merits; only new, temporary obstacles to execution can be considered.
