In reality the EU is mostly a toothless tiger against poland

Let's be realistic here. The EU just can't afford any other "xit", polxit or whatever xit, just can't. Especially one without vaseline; it sets a dangerous political precedent for a start, during a very very very fragile financial and economical situation where there's little to no room for a market rollercoaster ride (lockdown costs+existing deficits+fucked economy). And if they fine poland, not only they'll likely have to sit on the tab at least for a little while and what is the EU they going to do about it? Invade poland? With what? There's no EU army. Needless to mention that poland is part of NATO, ah

HOpefully they will hold it against the bribery and the threat

A pity that they consider modern russia as a sworn ennemy and they probably still do not know/understand who started the bolsevik revolution.

If EU can control the courts then they can shoot down legislation in a country and prevent the will of the people for their nation.
