A Polish lecturer who said that Jews had practiced “ritual murders” will not be reprimanded because his claims are the subject of “scientific discourse,” the university that employs him said.

An internal ethics panel made the decision not to take disciplinary action against Tadeusz Guz, a priest and faculty member at the Catholic University of Lublin, for a second time after again reviewing complaints over a 2018 speech he gave in Warsaw.

“We know, ladies and gentlemen, that the facts of ritual murder cannot be erased from history. Why? Because we, the Polish state, in our archives, in the surviving documents, have evidence spread across centuries when Jews lived together with our Polish nation,” he said.
