[vague][4][5] The stated objectives of the League are to defend the name of Poland and the Polish people against acts of vilification in the international media or historical misrepresentation in the world of politics.

[18] The League collected tens of thousands of signatures in order to pass the Amendment to the Act on the Institute of National Remembrance, which has been criticized by historians as an attempt to silence discussion of Polish complicity in wartime atrocities.

Świrski, who heads the league, was instrumental in passing the bill and was possibly the only person consulted prior to the law being presented to parliament by the Justice ministry.

[19] In 2018, Polish Holocaust scholar Jan Grabowski sued the organization for libel after it accused him of "falsif[ying] the history of Poland" and "proclaiming the thesis that Poles are complicit in the extermination of Jews" in an open letter.

[22] In 2019 the league funded a lawsuit against Grabowski and Barbara Engelking, editors of the 2018 Dalej jest noc ("Night Without End"), accusing them of defamation.

[25] In 2020, the organization released a 74-page report titled "Opportunities to Prevent Defamation on Netflix-type Streaming Platforms" in which it examined 557 fiction works and 47 documentaries for "anti-Polish" content.
