Judgment_paragraph 73 · European Commission v Romania (C-549/18)

73As regards, first, the seriousness of the infringement, it must be borne in mind that the obligation to adopt national measures for the purposes of ensuring that a directive is transposed in full and the obligation to notify those measures to the Commission are fundamental obligations incumbent on the Member States in order to ensure optimal effectiveness of EU law and that failure to fulfil those obligations must, therefore, be regarded as definitely serious (judgment of 8 July 2019, Commission v Belgium (Article 260(3) TFEU — High-speed networks), C‑543/17, EU:C:2019:573, paragraph 85). Furthermore, Directive 2015/849 is an important instrument for ensuring that the European Union’s financial system is effectively protected against the threats from money laundering and terrorist financing. The absence or inadequacy of such protection of the European Union’s financial system must be considered particularly serious in the light of its effects on public and private interests within the European Union.
