"This ARTICLE 19 policy paper proposes a set of recommendations to be used for interpreting and implementing those international obligations which prohibit all advocacy that constitutes incitement to discrimination, hostility or violence (“incitement” or “incitement to hatred”), as mandated by Article 20(2) of the International Covenant on Civil and Political Rights (“ICCPR”). The recommendations also apply to some of the provisions contained in Article 4 of the International Convention on Elimination of All Forms of Racial Discrimination (“ICERD”)."
