Judgment_paragraph 31 · A v B (C-184/14)

31The need for the uniform application of EU law requires that, to the extent that the provisions of Article 3(c) and (d) of Regulation No 4/2009 make no express reference to the law of the Member States for the purpose of determining the meaning and scope of that concept, that concept must be given an autonomous and uniform interpretation throughout the European Union (see, to that effect, judgment in Kásler and Káslerné Rábai, C‑26/13, EU:C:2014:282, paragraph 37).
