Judgment_paragraph 23 · A v Udlændinge- og Integrationsministeriet (C-89/18)

23In that regard, it is apparent from settled case-law of the Court that the ‘standstill’ clause contained in Article 13 of Decision No 1/80 prohibits generally the introduction of any new national measure having the object or effect of making the exercise by a Turkish national of the freedom of movement for workers on national territory subject to conditions more restrictive than those which applied at the time when Decision No 1/80 entered into force with regard to the Member State concerned (judgment of 29 March 2017, Tekdemir, C‑652/15, EU:C:2017:239, paragraph 25 and the case-law cited).
