European Union – Jurisdiction. The Court of Justice of the European Union gave a preliminary ruling, deciding that the first paragraph of art 22(1) of Regulation (EC) No 44/2001 should be interpreted as meaning that an action for the termination of co-ownership in undivided shares of immovable property by way of sale, by an appointed agent, fell within the category of proceedings 'which have as their object rights in rem in immovable property' within the meaning of that provision.
