The Court of Justice delivered yesterday (27 June 2019) its judgment in case C‑518/18 (RD v SC), which is about the EEO Regulation:

“Regulation (EC) No 805/2004 […] creating a European Enforcement Order for uncontested claims must be interpreted as meaning that, where a court is unable to obtain the defendant’s address, it does not allow a judicial decision relating to a debt, made following a hearing attended by neither the defendant nor the guardian ad litem appointed for the purpose of the proceedings, to be certified as a European Enforcement Order”.
