41Nevertheless, the fact that a matter falls within the competence of the Member States does not alter the fact that, in situations covered by European Union law, the national rules concerned must have due regard to the latter (see, to that effect, Case C-274/96 Bickel and Franz [1998] ECR I-7637, paragraph 17 (as regards national provisions in the sphere of criminal legislation and the rules of criminal procedure); Case C-148/02 Garcia Avello [2003] ECR I-11613, paragraph 25 (as regards national rules governing a person’s name); Case C-403/03 Schempp [2005] ECR I-6421, paragraph 19 (as regards national rules relating to direct taxation); Case C-145/04 Spain v United Kingdom [2006] ECR I-7917, paragraph 78 (as regards national rules determining the persons entitled to vote and to stand as candidates in elections to the European Parliament)).
