At the end of January 2018, the Sejm of the Republic of Poland passed an amendment to the Act on the Institute of National Remembrance. The law introduces fines or imprisonment of up to three years for public and contrary to the facts imputation of responsibility for the crimes of Nazi Germany to the Polish nation or state. Similar provisions exist in other countries, i.e. in Israel and Germany, where denial of the Holocaust can result in imprisonment of up to 5 years. Polish law does not restrict freedom of expression, artistic activity or scientific research concerning the Holocaust. The Act was signed by the President of the Republic of Poland at the beginning of February and entered into force on March 1, 2018.
