Yes if booted out.
No EU member can be booted out. You're reading too much of the Daily Express with its sensationalist and totally inaccurate headlines. There exists no mechanism to throw anyone out of the EU. That could change of course but it would have to be debated, discussed, formulated etc and would probably take a few years to finalize.
Don't get too exited, marxists. The whole "voting" likely won't happen and If it does, there will be far more vote "against" than one.
Why is it that anybody who objects to the idea of an authoritarian right wing government dismantling the modern Polish state and setting themselves up to govern forever, is a 'Marxist'. As far as I'm concerned the man was first cousin to Lucifer. Like most champions of the 'worker' including Lenin and Uncle Joe, he never did a day's hard graft in his life and his Utopian theories caused untold misery and hardship to billions. You should read about Welsh factory owner, Robert Owen, a TRUE champion of the working man who actually improved the quality of their lives with his social reforms including the eight hour working day, and that was back in the early 1800s.
Now, back to the EU. The voting I'm referring to is the vote on a resolution against Hungary and that will most definitely take place and will pass as the majority of MEPs are concerned not only about Poland but also about Hungary. Regarding Poland,we are still only at Article 7 stage one. After the 20 March deadline, another two thirds majority vote will be needed to move to Stage 2. The Parliament already has that. Then there will be another vote which requires a four fifths majority, that's the tricky one as it depends on those who've abstained up to that point, climbing down from the fence. The final vote would be for sanctions and that's the one that requires unanimity. That probably won't be until December of this year and by that time Hungary will also be subject to Article 7 which could prevent it from voting. Incidentally Romania is also in line for Article 7.
The good thing to come out of all this mess, is that now that's it's taken the plunge with Poland, the Commission seems to be more comfortable with invoking Article 7. They were guilty of being head in the sand with Hungary and this is the result, a divided EU in a crisis situation. So I suspect that from now on, they'll be much quicker to react to backsliding in other EU states - there's also no doubt that this will ultimately lead to mechanisms being introduced to expel rogue states from the Union.
