The Amendment to the Act on the Institute of National Remembrance of 2018 is a partly repealed Polish law that criminalized public speech attributing responsibility for the Holocaust to Poland or the Polish nation; the criminal provisions were removed again later that year, after international protests. Article 2a, addressing crimes against "Polish citizens" by "Ukrainian nationalists", also caused controversy. The legislation is part of the historical policy of the Law and Justice party which seeks to present a narrative of ethnic Poles exclusively as victims and heroes. The law was widely seen as an infringement on freedom of expression and on academic freedom, and as a barrier to open discussion on Polish collaborationism, leading to what has been described as "the biggest diplomatic crisis in [Poland's] recent history".
While the act does not mention the "Polish death camp" controversy (involving concentration camps that had been built by Nazi Germany during World War II on German-occupied Polish soil), the act's chief intent was to address that controversy. In 2019, the Constitutional Tribunal of Poland ruled that Article 2a was void and non-binding.
