Appeals were lodged both by the defense lawyer of Gerd Honsik and by the public prosecutor, who found the sentence too mild.
Honsik, 67, was found guilty of “Wiederbetaetigung” – which means “re-engaging” in Nazi era beliefs. The crime is punishable by up to 20 years in prison.
Honsik wrote a book, “Hitler Innocent?,” in which he attempted to justify some Nazi-era crimes.
He was originally convicted of neo-Nazi activities in 1992 for writings that defended Adolf Hitler’s Third Reich, but he fled to Spain, where authorities arrested him in October 2007 and subsequently extradited him.
