Guenter Deckert was arrested and served five years in prison in Germany for translating a speech by Fred Leuchter into German.

These statements caused a public outcry: spokespeople for the Jewish community crying foul, the prosecutor decrying Orlet’s opinions as “instructions” for denying the Holocaust, the German justice minister calling it “a slap in the face of all Holocaust victims”, and the Association of German Judges calling it “a slip of the footing”. As a consequence, the two judges were suspended (although they were reinstated a few months later^N1), and Deckert was ordered to a second retrial. At his third trial, in April 1995, Deckert was sentenced to two years in prison without probation, for Gefährliche Politische Brandstifung (“dangerous political incendiarism”), by Judge Wollentine in Karlsruhe.^[5][6]

Whilst in prison, Deckert wrote a letter to the then-chairman of the Central Council of Jews, Michel Friedman, strongly urging him, as a Jew, to leave Germany. This letter was published in the NPD newspaper. Deckert was charged with incendiarism a second time, and at trial in Mannheim in 1997 he was found guilty and sentenced to an additional two years and three months in prison. During the trial, Decker’s lawyer, Ludwig Boch, based the defence upon the assertion that the Holocaust was a “legend” invented by the Jews.
