46However, as the Advocate General noted in point 49 of his Opinion, while the establishment and application of those rules falls within the competence of the Member States, the latter must exercise that competence in accordance with EU law, and in particular the principle of effectiveness. Accordingly, they may not render the implementation of EU law impossible in practice or excessively difficult and, specifically, in the area of competition law, they must ensure that the rules which they establish or apply do not jeopardise the effective application of Articles 101 TFEU and 102 TFEU (see, to that effect, judgment of 14 June 2011, Pfleiderer, C‑360/09, EU:C:2011:389, paragraph 24). The authorities designated under Article 35(1) of Regulation No 1/2003 must ensure that those Treaty articles are applied effectively in the general interest (judgment of 7 December 2010, VEBIC, C‑439/08, EU:C:2010:739, paragraph 56).
