44It is settled case-law that a measure which is liable to hinder the free movement of workers enshrined in Article 45 TFEU can be permissible only if it pursues a legitimate objective compatible with the Treaty and is justified by overriding reasons in the public interest. It is also necessary, in such a case, that its application be appropriate for ensuring the attainment of the objective thus pursued and not go beyond what is necessary to attain that objective (see, by analogy, judgment of 12 December 2013, Imfeld and Garcet, C‑303/12, EU:C:2013:822, paragraph 64 and the case-law cited).
