Kernrechtsfrage
Whether the foreign court's jurisdiction could be reviewed in enforcement proceedings because of an allegedly manifestly wrong reliance on Art. 5(3) LugÜ.
Extrahierter Entscheid
No. The jurisdiction of the court of origin is generally not reviewable under Art. 28(4) LugÜ; even a serious misapplication of jurisdictional rules cannot be raised as public policy.
Extrahierte Begründung
The Convention excludes review of the origin court's jurisdiction except for the narrow exceptions expressly provided. Alleged incorrect autonomous interpretation of the jurisdictional ground does not open a public-policy review.
