The draft report by the Venice Commission has been published in full :
The most important conclusion is here.
However, as long as the situation of constitutional crisis related to the Constitutional Tribunal remains unsettled [...], not only is the rule of law in danger, but so is democracy and human rights.
The report contains considerable criticism of the government's arguments, particularly the way that PiS have attempted to portray judges as being political and belonging to political camps. Furthermore, it expresses alarm over the way that the government has been making defamatory statements about judges on the Constitutional Tribunal.
If PiS refuse to accept the opinion of the Venice Commission, then the pressure can only increase from the EU. Stopping agricultural payments should do the trick.
Just to provide an English language news source about the Venice Commission's opinion:
"I want a return to normalcy. There is an attack on the rule of law in Poland," said Beata, a Warsaw translator. "I see the attack on the Constitutional Tribunal as an attack on the state."
Putin must be loving every second of this. PiS are tearing Poland apart, and with it, leaving behind a weak, debt-ridden corrupt mess that will fall victim easily to Russian imperialism.
