I just read about the arrest of Mariusz Kamiński and Maciej Wąsik at the presidental palace and the fight over if their pardon was legal.
From what I understand the Supreme Court of Poland ruled that their 2015 pardon from Duda was invalid because a pardon can only be granted after a final verdict. The Constitutional court ruled that the pardon was valid.
The lower court has entered a final verdict convicting them to 2 years of jail. Now that the final verdict is there what is stopping Duda from pardoning them again? Duda is still defending them, so pardoning should be an easy thing to do.
