27However, while the establishment and application of those rules falls within the competence of the Member States, they must none the less exercise that competence in accordance with European Union law. In particular, the rules applicable to actions for safeguarding rights which individuals derive from the direct effect of EU law must not be less favourable than those governing similar domestic actions (principle of equivalence) and must not make it in practice impossible or excessively difficult to exercise rights conferred by EU law (principle of effectiveness) (see Courage and Crehan, paragraph 29; Manfredi, paragraph 62; and Case C-397/11 Jörös [2013] ECR, paragraph 29). Specifically, in the area of competition law, those rules must not jeopardise the effective application of Articles 101 TFEU and 102 TFEU (see Pfleiderer, paragraph 24, and Case C-439/08 VEBIC [2010] ECR I-12471, paragraph 57).
