And it sounds like more something the LGBT gang would do rather than Duda!
Let's talk about the last PiS government, shall we?
We can start with this little gem :
The delegation was informed that in 2003 the Polish government passed legislation prohibiting the Prosecutor General from intervening in particular cases. Between 2004 and 2005, the then Minister of Justice was diligent in following this rule and did not intervene in individual cases.
This changed in November 2005, when the Minister of Justice held his first press conference in which he began to comment on individual cases.
ccbe.eu/fileadmin/user_upload/NTCdocument/11_2007_Nov06_Report1_1194344860.pdf (chapter 4, page 79 - there are many more examples there of how PiS abused the position and interfered directly with legal matters)
So that's one count already for
actual practice
You'll find further examples in that document, including attempts to smear independent prosecutors as being members of the PZPR. It's exactly the tactic used in the later days of the PRL and DDR to destroy political opponents. There's even a splendid quote by the deputy minister of justice, who manages to explain that the prosecutors should be subject to political interference.
Let's move on.
Then we had the now-infamous example -
Meanwhile, the Polish government's anti-gay obsession reached truly absurd lengths last May, when a high-ranking official suggested the BBC TV children's show "Teletubbies" promoted a homosexual lifestyle.

Then we can talk about the government itself, which was described as...
domestic policies were bigoted and oppressive, from its anti-gay rhetoric to its ruthless, witch-hunting treatment of opponents as anti-Polish and potentially treacherous.
And we even had many examples of them using the worst sort of nepotism -
unpicking the web of political patronage with which the Kaczynski twins smothered all public appointments
And of course, more references to just how socialist PiS were -
Here is the alliance, which seems so strange in the west but so natural in post-communist Europe, between nationalism and the "socialist" ideals of equality and the dignity of labour.

Sorry, but history has shown the 2005-2007 PiS government to be one of the worst in history. Political office was used and abused on an unbelievable scale, and everything that you mentioned is exactly what PiS would introduce if they had unrestrained power.
Tell me Polonius, do you see Hungary as a good example for Duda to try and follow?
