Convention on cybercrime). International law Some council-member states proposed an additional protocol to the Council of Europe Cybercrime Convention, addressing materials and "acts of racist or xenophobic nature committed through computer networks"; it was negotiated from late 2001 to early 2002, and, on 7 November 2002, the Council of Europe Committee of Ministers adopted the protocol's final text titled Additional Protocol to the Convention on Cyber-crime, Concerning the Criminalisation of Acts of a Racist and Xenophobic Nature Committed through Computer Systems, ("Protocol"). It opened on 28 January 2003, and became current on 1 March 2006; as of 30 November 2011, 20 States have signed and ratified the Protocol, and 15 others have signed, but not yet ratified it (including Canada and South Africa). The Protocol requires participant States to criminalize the dissemination of racist and xenophobic material, and of racist and xenophobic threats and insults through computer networks, such as the Internet. Article 6, Section 1 of the Protocol specifically covers Holocaust Denial, and other genocides recognized as such by international courts, established since 1945, by relevant international legal instruments. Section 2 of Article 6 allows a Party to the Protocol, at their discretion, only to prosecute the violator if the crime is committed with the intent to incite hatred or discrimination or violence; or to use a reservation, by allowing a Party not to apply Article 6 – either partly or entirely. The Council of Europe's Explanatory Report of the Protocol says that the "European Court of Human Rights has made it clear that the denial or revision of 'clearly established historical facts – such as the Holocaust – ... would be removed from the protection of Article 10 by Article 17' of the European Convention on Human Rights" (see the Lehideux and Isorni judgement of 23 September 1998); Two of the English-speaking states in Europe, Ireland and the United Kingdom, have not signed the additional protocol, (the third, Malta, signed on 28 January 2003, but has not yet ratified it). On 8 July 2005 Canada became the only non-European state to sign the convention. They were joined by South Africa in April 2008. The United States government does not believe that the final version of the Protocol is consistent with the United States' First Amendment Constitutional rights and has informed the Council of Europe that the United States will not become a Party to the protocol.
