101As regards Article 10 ECHR, it must be observed that, admittedly, that convention is not, as long as the European Union has not acceded to it, a legal instrument which has been formally incorporated into EU law. Consequently, the examination of the validity of an act of EU secondary legislation must be carried out solely in the light of the fundamental rights guaranteed by the Charter. However, it should be recalled, on the one hand, that, under Article 6(3) TEU, fundamental rights recognised by the ECHR constitute general principles of EU law and, on the other hand, that it follows from Article 52(3) of the Charter that the rights contained in the Charter which correspond to rights guaranteed by the ECHR are to have the same meaning and scope as those laid down by the ECHR. According to the explanations relating to that provision, which, in accordance with the third subparagraph of Article 6(1) TEU and Article 52(7) of the Charter, have to be taken into consideration for the purpose of interpreting it, the meaning and scope of the guaranteed rights are determined not only by the text of the ECHR but also, in particular, by the case-law of the ECtHR. It is also apparent from those explanations that Article 52(3) of the Charter is intended to ensure the necessary consistency between the rights contained in the Charter and the corresponding rights guaranteed by the ECHR, without thereby adversely affecting the autonomy of EU law and that of the Court of Justice of the European Union. Moreover, it must be pointed out that that equivalence between the freedoms guaranteed by the Charter and those guaranteed by the ECHR has been formally expressed in relation to freedom of expression (see judgment of 31 May 2018, Korwin-Mikke v Parliament, T‑770/16, EU:T:2018:320, paragraph 38 and the case-law cited).
