Judgment_paragraph 62 · Criminal proceedings against FU and Others (C-410/21)

62As the Court has already held, that procedure of dialogue and reconciliation constitutes an essential prerequisite for determining whether the conditions for the existence of a fraud are met and, therefore, to draw all useful conclusions as regards the validity of the A1 certificates at issue and the social security legislation applicable to the workers concerned. Thus, a court of the host Member State hearing criminal proceedings such as those in the main proceedings cannot take no account of that procedure of dialogue and reconciliation (see, by analogy, judgment of 2 April 2020, CRPNPAC and Vueling Airlines, C‑370/17 and C‑37/18, EU:C:2020:260, paragraphs 71 and 73).
