19According to the Court's case-law, a measure restricting one of the fundamental freedoms guaranteed by the Treaty may be justified only if it pursues a legitimate objective which is compatible with the Treaty and respects the principle of proportionality. For that reason, such a measure must be appropriate for securing the attainment of the objective which it pursues and must not go beyond what is necessary in order to attain it (see, in particular, Case C-19/92 Kraus [1993] ECR I-1663, paragraph 32, and Case C-100/01 Oteiza Olazabal [2002] ECR I-10981, paragraph 43).
