The Act on the Institute of National Remembrance – Commission for the Prosecution of Crimes against the Polish Nation (Polish: Ustawy o Instytucie Pamięci Narodowej - Komisji Ścigania Zbrodni przeciwko Narodowi Polskiemu) is a 1998 Polish law that created the Institute of National Remembrance. This memory law was amended twice, in 2007 and 2018.
The 1998 Act's Article 55 criminalized historical negationism of crimes committed against Poles or Polish citizens by Nazi or communist polities; of crimes against peace or humanity; of war crimes; and of political repression—all these being listed in Sections 1 a and 1 b of Article 1. While Holocaust denial was not explicitly mentioned, it is understood to be implicity criminalized.[1]
The 2007 Amendment dealt with lustrations conducted in Poland.
The 2018 Amendment added an Article 55a, which seeks to defend the "good name" of Poland and its people against unfounded accusations of complicity in the Holocaust.[2] Also added by the 2018 Amendment was an Article 2a, addressing crimes against "Polish citizens" by "Ukrainian nationalists", which has been seen as an act of exclusion against ethnic minorities.[3] Following an international outcry, defamation of Poland and the Polish people through unfounded accusations of complicity in the Holocaust, under Article 55a, was amended to a civil offense that can be tried in civil courts.[3] Article 2a was appealed by Polish President Andrzej Duda and was found to be unconstitutional by the Polish Constitutional Tribunal, which declared it null and void.[4]
