Review the Global Vision of the Holocaust, a Holocaust denial conference in Tehran sponsored by the Iranian regime of Mahmoud Ahmadinejad. 2008 extradition attempt In 2008, the German federal authorities attempted unsuccessfully to extradite Töben from the United Kingdom under a European arrest warrant for allegedly publishing "antisemitic and/or revisionist" material on his website, which he writes from his home in Australia, and is a crime that does not exist in Britain. The European Arrest Warrant had three boxes ticked: racism, xenophobia and cybercrime, which did not fulfill British legal requirements and so the EAW was judged to be deficient. On 1 October 2008, Töben was detained at Heathrow Airport while flying from the United States to Dubai. In Westminster Magistrates' Court the next day, he objected to the terms of the warrant, claiming that he was protected by the terms of the Schengen agreement and said that his historical and political views had motivated the German authorities' decision to issue the warrant.

The German authorities later withdrew their appeal, after the Crown Prosecution Service advised them that in the light of further information they had provided about the location of the alleged offence, it would not have been possible to satisfy the courts that the offence was extraditable. This is because under common law it is not an offence to express an opinion, as is
