Question juridique clé
Whether the appealable decision on child return under the Hague Convention could be challenged by constitutional complaint and whether novelties were admissible.
Solution extraite
The Court held that Hague child-return proceedings are not civil litigation under the OG; the only available remedy is constitutional complaint, and new facts were inadmissible.
Motifs extraits
The Convention functions as administrative mutual legal assistance. In constitutional complaint proceedings based on treaty violations, novas are barred.
