Thank you Antonio Pastor for signalling Central Santa Lucia L.C. v. Meliá Hotels International S.A., litigation on which also more background here. The Spanish courts at MAllorca (appeal expected) have declined jurisdiction concerning confiscated property in Cuba after the end of suspension of Title III of the Libertad Act (the “Helms-Burton Act”, well known to trade and international lawyers alike) on the basis of sovereign immunity, as Antonio explains.
However as I understand Antonio’s summary (I fear I do not have Spanish to consult the judgment myself), the Court obiter also applied Article 24(1) Brussels Ia reflexively: if Brussels Ia grants exclusive jurisdiction to the courts of the Member State in which the property is situated in proceedings which have as their object rights in rem in immovable property or tenancies of immovable property, then EU Courts should decline jurisdiction if that real estate happens to be located ex-EU. Readers will remember the discussions on this issue in one or two earlier postings on this blog.
Interesting, to say the least.
Geert.
