Judgment_paragraph 23 · European Commission v Ireland (C-87/14)

23In addition, with regard, in particular, to a complaint concerning the implementation of a national provision, proof of a Member State’s failure to fulfil its obligations requires production of evidence different from that usually taken into account in an action for failure to fulfil obligations concerning solely the terms of a national provision and, in those circumstances, failure to fulfil obligations can be established only by means of sufficiently documented and detailed proof of the alleged practice of the national administration for which the Member State concerned is answerable (see judgments in Commission v Belgium, C‑287/03, EU:C:2005:282, paragraph 28 and Commission v Germany C‑441/02, EU:C:2006:253, paragraph 49).
