Well an euroskeptic government is out and a new as pro-EU as is possible to be (Donald Tusk was President of the EU Council) is in, so all is well... You may recognise a pattern that is at play in other countries both in the EU and outside.
What matters are facts: Poland violated several points of the Treaty of the European Union, the EU Charter and CJEU rulings all stating the same thing: to be part of the European Union rule of law must be respected.
In other words: the judicial branch of power has to be independent. Politicians write laws. Judges and not politicians, rule on whether they are respected or not.
And again, I'm Polish, I know what I'm talking about: the previous government went far in bending the constitution, controlling the press and the judges taking our country step after step towards a dictatorship.
