Poland is poised to enact a bill that would impose up to three years of jail time on anyone who uses phrases such as Polish death camps to refer to the Nazi concentration camps located in the country during the Holocaust.

The bill was approved by the Polish Senate on Thursday. President Andrzej Duda has 21 days to decide whether it should be signed into law.

The move seeks to punish those who suggest that Poland was complicit in the atrocities that Nazis wreaked on its soil during World War II. It has the backing of Polands ruling right-wing and nationalist Law and Justice party (PiS), according to Reuters.

A number of Jewish groups, including the Anti-Defamation League , Bnai Brith International , and the American Jewish Committee, have urged Duda to veto the bill.

ADLs National Director Jonathan Greenblatt said that theres no doubt Poland was a victim of the Nazis and their brutal occupation. However, Greenblatt feared that silencing free speech about Poles involvement with the Holocaust would hurt survivors and their families.

We understand and sympathize with Polands frustration at the use of the term Polish Death Camps, but this law goes well beyond that issue, Greenblatt said in a statement. It raises the possibility that anyone offering Holocaust survivor testimony about actions by individual Poles could be charged with a crime. This is unacceptable and could silence the voices of survivors and their families.
