The head of Vienna's Jewish community has attacked a Graz court's decision not to prosecute a right-wing magazine which claimed Mauthausen concentration camp survivors were themselves criminals.
Oskar Deutsch said the failure to put Aula magazine writer Manfred Duswald and publisher Martin Pfeiffer on trial was a "heinous perpetrator-victim role reversal".
Charges had been filed by Green Party politician Harald Walser, who has demanded an explanation for the decision not to prosecute.
It is illegal under Austrian law to belittle Nazi crimes during the Holocaust.
