No. The EC refered Poland to the ECJ to protect judges from political control
Indeed. It apparently is difficult for some in the USA to realise that the "separation of powers" doctrine is a product of "the Enlightenment", and not an invention by the Founding Fathers of the United States.
"The Enlightenment" was a European intellectual movement of the late 17th and 18th centuries emphasizing reason and individualism rather than tradition. It was heavily influenced by 17th-century philosophers such as Descartes, Locke, and Newton, and its prominent figures included Kant, Goethe, Voltaire, Rousseau, and Adam Smith.
"Separation of powers" is a doctrine of constitutional law under which the three branches of government (executive, legislative, and judicial) are kept separate. This is also known as the system of checks and balances, because each branch is given certain powers so as to check and balance the other branches
That's why the separation of powers is such a fundamental part of the European way of organizing society. The Polish government is trying to replace the impartial Judicial by a State-controlled farce. It's hard to imagine why someone from the USA would not see how wrong that is, unless they don't like the USA constitution.
