The scope of binding effect of a certificate of applicable social security legislation (E101 and A1) on Member State's Courts in the event of a fraud — comments against the judgments of the CJEU in C-359/16, C-527/16, C-370/17 and C-37/18 and C-17/19 — pa

The author analyses case law of the Court of Justice of the European Union on the binding effect of a certificate on legislation applicable (E101 and A1) for courts of a Member State in the event of fraud. Both in Polish literature and in case law, judgments in this area are assigned with different effects. What seems to prevail is a believe that the binding force of the abovementioned certificates has been weakened. This study aims at critical analysis of such a view, as well as at establishing conclusions resulting from the emerging jurisprudence.
