In December 2007, Plevris was initially found guilty of inciting racial hatred by a Greek court based on excerpts and quotations in his book The Jews: The Whole Truth.
The court justified his acquittal by stating "The defendant does not revile the Jews solely because of their racial and ethnic origin, but mainly because of their aspirations to world power, the methods they use to achieve these aims, and their conspiratorial activities".
[7] In his 2000 book The Greek Student Movement in Italy Nikos Kleitsikas wrote that Plevris was a CIA or Mossad agent during the Cold War and participated in bombings.
The Greek court of appeals vindicated him and the defendants were forced to pay 15,000 euros in compensation for the not well documented claim that Plevris organized and participated in provocative acts to pave the path for the coup d'état that brought into power the Greek military junta of 1967–1974, but the court found and accepted that the defendant proved Plevris' fascist leanings, as well as his connection with European neo-fascist terrorist groups and personalities (such as Pino Rauti and the far-right terrorist group Ordine Nuovo), his collaboration with the Greek junta and his collaboration with various secret services, based on Plevris' own statements in interviews he had given.
Shortly after its publication in June 2006 the Central Board of Jewish Communities in Greece and the Greek Helsinki Monitor brought a suit against Plevris for "insult of Jews" and "injury to Judaism".
[9] Shortly after its publication the Central Board of Jewish Communities in Greece and the Greek Helsinki Monitor brought a suit against Plevris for "insulting Jews" and "injury to Judaism".
[11] After two months, and the support of the Central Board of Jewish Communities in Greece, he eventually succeeded and so, in December 2006, Plevris was indicted for violation of Article 191 of the Penal Code, the dissemination of false news.
In the book, Plevris describes himself as a "Racist, anti-democrat, anti-Semite" (p. 600), subscribes to the myth of the Protocols of the Elders of Zion (which he presents as authentic and valid evidence against the Jews), characterizes Jewish children in the concentration camps as "very fat" and "well-fed", claims that Jews are "subhuman" (p. 583) "mortal enemies", and criticizes the Nazis for "not ridding Europe of Jewish Zionism".
However, Plevris contends that "Of the 1,400 pages of my large book, the condemnation encompasses only several paragraphs, of which portions were extracted, with the result that another meaning was given to the words and truth is distorted due to the alteration of phrases".
[16] Plevris appealed and was eventually acquitted on 27 March 2009; his acquittal caused a controversy as to whether the Greek justice system failed to enforce Greece's antiracist legislation.
