Q:

Do Polish citizens support law that allows judges to be disciplined for criticizing the system?

Polish President Duda has adopted on October, 2nd 2020 a divisive law that allows judges to be disciplined for criticizing the system. The legislation, which has drawn condemnation from the European Union, bars judges from questioning judicial appointments made by the president and forbids them from engaging in political activity. It has been criticized by the European Union, some judges and some political 
But how do Polish feel about it ? I haven't read any article from Polish sources telling if the people where supportive or against it. Furthermore PiS, president Duda party, seems likely to win another election. 

A:

I'm not totally sure this is answering your question, but since the EU has taken action against Poland on this matter, a related poll is probably a good proxy indicator.

Respondents were also asked about the European Commission's conflict over Poland's judicial reform conflict. For that question, 22 percent of respondents viewed the European Commission's actions negatively and 20 percent “rather negatively". Another 30 percent viewed the actions positively and 17 percent rather positively.

As you probably know, the opposition has organized protests in Poland on the matter etc.
