In the case of A.K. and Others (19.11.2019) the CJEU dealt with the issue of the independence of the Disciplinary Chamber of the Polish Supreme Court. In setting out the requirements to be fulfilled under EU law for a court to be independent and impartial, it relied on the second paragraph of Article 47 of the Charter (right to a fair trial), thereby pointing out that, by virtue of Art. 52(3) of the Charter, “the Court must … ensure that the interpretation which it gives to the second paragraph of Article 47 of the Charter safeguards a level of protection which does not fall below the level of protection established in Article 6 of the ECHR, as interpreted by the European Court of Human Rights” (§ 118).
The CJEU then went on to give an overview of its own case-law on the independence and impartiality of courts (including C-216/18 PPU, Minister for Justice and Equality (Deficiencies in the system of justice) and C-619/18, Commission v. Poland (Independence of the Supreme Court)) and pointed out that its interpretation of article 47 of the Charter was borne out by the case-law of the European Court of Human Rights on Article 6 § 1 of the Convention (§ 126) which the CJEU then proceeded to describe in some detail.
One may just wonder why the CJEU did not mention that same Strasbourg case-law in its previous judgment in C-619/18 mentioned above, which deals with very similar issues.
