The Court of Justice delivered today its judgment in Case C‑729/19 (TKF v Department of Justice for Northern Ireland), which is about the Maintenance Regulation:

“1. Article 75(2)(a) of Council Regulation (EC) No 4/2009 of 18 December 2008 on jurisdiction, applicable law, recognition and enforcement of decisions and cooperation in matters relating to maintenance obligations must be interpreted as applying only to decisions given by national courts in States which were already members of the European Union on the date of adoption of those decisions.

2. Regulation No 4/2009 must be interpreted as meaning that no provision of that regulation enables decisions in matters relating to maintenance obligations, given in a State before its accession to the European Union and before the date of application of that regulation, to be recognised and enforced, after that State’s accession to the European Union, in another Member State”.
