I have no idea. But doing anything unconstitutional, even if it is done in good faith, is certainly not the right thing to do because one day it will backfire (e.g. the next government could do the very same thing saying that "X did it, so we can do it too"), or the next government could easily revert the dissmision by saying it was against the law. That's why you need a constitutional majority to perform actions like that - by having a constitutional majority you can be sure that the great majority of civilians approve your actions, not just (like in this case) 37%.
Also, in this case the case isn't really about corrupted judges. While yes, there might be few bad apples there, but most of the Supreme Court judges are respected. Or at least were until the party started spreading their propaganda: "they think they are above others", "they are the relict of the Polish People Republic", "they are thieves" (there are two cases where two judges stole something, one stole a pair of jeans and the other a pendrive; the one who stole jeans is retired now and has dementia) etc.
The problem with the proposed bill is that it doesn't fix any problems with the judgement system, it just replaces people and calls it a day.
