Judgment_paragraph 31 · A v Udlændinge- og Integrationsministeriet (C-89/18)

31As is apparent from the Court’s case-law, a restriction whose object or effect is to make the exercise by a Turkish national of the freedom of movement of workers in national territory subject to conditions more stringent than those applicable on the date of entry into force of Decision No 1/80 is prohibited, unless it falls within the restrictions referred to in Article 14 of that decision or it is justified by an overriding reason in the public interest, is suitable to achieve the legitimate objective pursued and does not go beyond what is necessary in order to attain it (see judgment of 7 August 2018, Yön, C‑123/17, EU:C:2018:632, paragraph 72 and the case-law cited).
