37Under Article 51(1) of the Charter, its provisions are addressed to the Member States only when they are implementing Union law and, according to settled case-law, the concept of ‘implementation of Union law’ within the meaning of that provision presupposes a degree of connection between an act of Union law and the national measure at issue which goes beyond the matters referred to or the indirect effects of one of the matters on the other, having regard to the assessment criteria laid down by the Court (see, to that effect, judgments of 22 January 2020, Baldonedo Martín, C‑177/18, EU:C:2020:26, paragraphs 57 to 59, and of 16 July 2020, Adusbef and Others, C‑686/18, EU:C:2020:567, paragraphs 51 and 52).
