Article 5 of Council Regulation (EC) No 1346/2000 of 29 May 2000 on insolvency proceedings must be interpreted to the effect that security created by virtue of 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 is, by operation of law, to be subject to a public charge and that property owner must accept enforcement of the decision recording that tax debt against that property, constitutes a ‘right in rem' for the purposes of that article.
