Judgment_paragraph 43 · Ordine Nazionale dei Biologi and Others v Presidenza del Consiglio dei Ministri (C-96/20)

43In that regard, it may nevertheless be observed, as regards the argument put forward by the applicants in the main proceedings concerning the alleged failure to comply with the requirement of mutual recognition imposed by Directive 2005/36/EC of the European Parliament and of the Council of 7 September 2005 on the recognition of professional qualifications (OJ 2005 L 255, p. 22), as amended by Directive 2013/55/EU of the European Parliament and of the Council of 20 November 2013 (OJ 2013 L 354, p. 132), which harms migrant biologists wishing to carry out the duties of a responsible person of a blood establishment in Italy, that that argument, which may be admissible even if raised in a request for a preliminary ruling, regardless of the fact that it arises in a purely internal situation (see, by analogy, judgment of 21 February 2013, Ordine degli Ingegneri di Verona e Provincia and Others, C‑111/12, EU:C:2013:100, paragraphs 33 to 35), must in any event be rejected on the substance.
