A/68/329 134. As a consequence of this scapegoating rhetoric, restrictive and punitive immigration and asylum policies are emerging in some countries. Such policies often provide for the detention of undocumented migrants and asylum seekers. IV. Conclusions and recommendations 135. The Special Rapporteur is grateful to all States for the information provided on the measures implemented pursuant to General Assembly resolution 67/154. He also appreciates the contributions received from other organizations and civil society. He recalls the importance of full cooperation with his mandate as stipulated in Human Rights Council resolution 16/33. 136. The Special Rapporteur notes that some States referred in their replies to an increase in their territory of the phenomena identified in General Assembly resolution 67/154 and to the proliferation of extreme right-wing groups. Others stressed that no such phenomena existed within their borders. The Special Rapporteur wishes to emphasize that the human rights and democratic challenges posed by extremist political parties, movements and groups are universal and no country is immune from them. He calls upon States to increase their vigilance and be proactive in strengthening efforts and political will to recognize and effectively address them. 137. The Special Rapporteur wishes to stress that any commemorative celebration of the Nazi Waffen SS organization and its crimes against humanity, whether official or non-official, should be prohibited by States. The Special Rapporteur wishes to recall paragraph 9 of General Assembly resolution 67/154, which provides that such manifestations do injustice to the memory of the countless victims of crimes against humanity committed in the Second World War, in particular those committed by the SS organization and by those who fought against the anti-Hitler coalition and collaborated with the Nazi movement, and negatively influence children and young people, and that failure by States to effectively address such practices is incompatible with the obligations of States Members of the United Nations. 138. The Special Rapporteur welcomes the information provided regarding the ratification of a range of instruments, including the International Convention on the Elimination of All Forms of Racial Discrimination and its inclusion in national legal and constitutional frameworks. He urges those States that have not yet done so to ratify the Convention and make the declaration under its article 14, thus providing competence to the Committee on the Elimination of Racial Discrimination to receive and consider communications from individuals or groups of individuals within its jurisdiction claiming to be victims of a violation by a State party of any of the rights set forth in this Convention. No communication can be received by the Committee if it concerns a State party that has not made such a declaration. 139. Several countries informed the Special Rapporteur that their constitutions and legislation enshrined the principles of equality and non-discrimination and prohibited incitement to racial, religious and national hatred. Furthermore, the Special Rapporteur notes that some countries have adopted legislation specifically to tackle the challenges posed by extremist political parties, movements and groups and have elaborated legal or constitutional provisions to 13-43012 21/25
