62The Court has consistently held that where a Community regulation does not specifically provide any penalty for an infringement or refers for that purpose to national laws, regulations and administrative provisions, Article 10 EC requires the Member States to take all measures necessary to guarantee the application and effectiveness of Community law. For that purpose, while the choice of penalties remains within their discretion, they must ensure in particular that infringements of Community law are penalised in conditions, both procedural and substantive, which are analogous to those applicable to infringements of national law of a similar nature and importance and which, in any event, make the penalty effective, proportionate and dissuasive (Case 68/88 Commission v Greece [1989] ECR 2965, paragraphs 23 and 24; Case C-326/88 Hansen [1990] ECR I-2911, paragraph 17; Case C-36/94 Siesse [1995] ECR I-3573, paragraph 20, and Case C-177/95 Ebony Maritime and Loten Navigation [1997] ECR I-1111, paragraph 35).
