[5] Sadurski is a vocal critic of the Law and Justice (PiS) party in Poland,[3][4] which he describes as autocratic and authoritarian.

[10] Hundreds of law professors signed a letter in support of Sadurski, stating that there was "a coordinated harassment campaign by the Polish ruling party against a well-known and respected academic who has clearly struck a nerve with his powerful critique of the situation in his native country".

[17] The Human Rights Institute of the International Bar Association also called for charges against Sadurski to be dropped.

Former Australian High Court judge Michael Kirby commented: "Poland’s citizens, including Professor Sadurski, must always have the ability to criticise the government without fear of retribution or imprisonment.

"[18] Scholars at Risk characterizes the prosecution of Sadurski as "apparent retaliation for the peaceful exercise of the right to freedom of expression" and states that state crackdowns on free expression cause "a chilling effect on academic freedom and undermine democratic society generally".
