European Union – Jurisdiction. The Court of Justice of the European Union gave a preliminary ruling, deciding that, art 5 of Council Regulation (EC) No 1346/2000 had to be interpreted to the effect that security created by a provision of national law, such as that at issue in the main proceedings, by which the real property of a person owing real property taxes was, by operation of law, to be subject to a public charge and that property owner had to accept enforcement of the instrument recording that tax debt against that property, constituted a 'right in rem' for the purposes of that article.
