The Court of Appeal in the southern city of Kraków issued a final interim order in a civil case brought by the Auschwitz-Birkenau Memorial and Museum.
The museum sued Braun in 2025 after he denied the existence of gas chambers at Auschwitz and questioned the museum’s credibility in a radio interview.
Braun, a far-right member of the European Parliament, is banned from publicly spreading statements that damage the museum’s good name and image, whether orally or in writing. The ban remains in force until December 11.
The court said the ban applies to claims that the museum uses a “pseudo-historical narrative,” that its message “does not meet the criteria of historical and scientific methodology,” and that research into the gas chambers at Auschwitz-Birkenau is being blocked by the museum itself.
Braun must also publish a post on his profile informing the public about the court order.
The case began after Braun said in a July 2025 radio interview that “ritual murder is a fact, and, let us say, Auschwitz with gas chambers is unfortunately fake.”
Asked to clarify his remarks, he said the museum’s presentation was “pseudo-historical” and did not meet scholarly standards “in all details.”
He also claimed that research into the gas chambers was being prevented by the museum. The journalist then ended the interview.
"Ritual murder" is a fake, libelous claim that has been used for centuries by antisemites to inflame anti-Jewish sentiments.
Auschwitz-Birkenau was the largest Nazi German concentration and extermination camp in occupied Poland. More than 1.1 million people, mostly Jews, were murdered there during World War II.
The state museum in the town of Oświęcim preserves the site and conducts historical, archival and educational work.
Museum director Piotr Cywiński called Braun’s remarks “scandalous and false.”
He said denying the existence of gas chambers at Auschwitz was an act of Holocaust denial punishable by law and an insult to the memory of the victims.
He also described the comments as an open denial of historical truth and an attempt to introduce manipulation based on antisemitism, falsehood and hatred into public debate.
The first interim order in the case was issued by the Kraków Regional Court on December 11, 2025. It granted the museum’s request in full, barring Braun from spreading false claims, ordering him to publish a notice about the ruling, requiring him to delete posts connected to the radio interview, and imposing possible fines for non-compliance.
Braun appealed. On June 3, the Court of Appeal in Kraków narrowed the order. It removed the requirement to delete posts and struck out the provisions on possible fines. It also modified the wording of the ban and of the notice Braun is required to publish.
Spokesman Robert Jurga said the court had partly accepted Braun’s arguments on the scope of the interim measures.
He said the order was limited to those claims by the museum that, at this stage, had been made plausible and were connected to the subject of the case.
Warsaw prosecutors have also opened preliminary proceedings over Braun’s questioning of Nazi crimes at Auschwitz.
