There are lots of articles related to Poland's highest court ruling that some parts of EU treaties are incompatible with the Polish constitution (example), but I cannot find the exact articles referred by the ruling (or at least a part of them).
I guess that article 47 mentioned here is one of "the parts":
It is well known that Article 47 of the Charter of Fundamental Rights of the European Union on the “Right to an effective remedy and to a fair trial” echoes Article 2 of the EU Treaty on the European Union (TEU), which considers “the rule of law and respect for human rights” as being among the values of the European Union.
This seems to be confirmed by this EU press release which also mentions article 19.1:
(..) the Commission notes that the law on the judiciary prevents Polish courts from assessing, in the context of cases pending before them, the requirements of judicial independence and from requesting a preliminary ruling. This is incompatible with the principle of primacy of EU law, the functioning of the preliminary ruling mechanism and Article 19(1) of the Treaty on European Union read in connection with Article 47 of the Charter of Fundamental Rights of the European Union (..)
Are these the only EU treaties parts indicated by the Poland's highest court?
