The Independent Inquiries into the actions of the United Nations during the tragedies of Rwanda (S/1999/1257) and the Balkans (A/54/549) in the 1990s demonstrated, in the worst possible way, that the United Nations had failed to protect the populations of these countries and had to do more to prevent genocide. With this in mind, in 2001 the UN Security Council in S/RES/1366 (2001) invited the Secretary-General “to refer to the Council information and analyses within the United Nations system on cases of serious violations of international law” and on “potential conflict situations” arising from “ethnic, religious and territorial disputes” and other related issues.
In 2004, on the tenth anniversary of the Rwanda genocide, the Secretary-General launched an Action Plan to Prevent Genocide and in consideration of the previous Council’s request, he appointed the first Special Adviser on the Prevention of Genocide.
The mandate of the Special Adviser is mainly outlined in a 2004 letter addressed by the Secretary-General to the President of the Security Council (S/2004/567). The letter lists the responsibilities of the Special Adviser and references the source of the mandate as Security Council resolution 1366 (2001), in particular the following paragraphs:
The Special Adviser will (a) collect existing information, in particular from within the United Nations system, on massive and serious violations of human rights and international humanitarian law of ethnic and racial origin that, if not prevented or halted, might lead to genocide; (b) act as a mechanism of early warning to the Secretary-General, and through him to the Security Council, by bringing to their attention potential situations that could result in genocide; (c) make recommendations to the Security Council, through the Secretary-General, on actions to prevent or halt genocide; (d) liaise with the United Nations system on activities for the prevention of genocide and work to enhance the United Nations capacity to analyse and manage information relating to genocide or related crimes.
The methodology employed would entail a careful verification of facts and serious political analyses and consultations, without excessive publicity. This would help the Secretary-General define the steps necessary to prevent the deterioration of existing situations into genocide. The Special Adviser would not make a determination on whether genocide within the meaning of the Convention had occurred. The purpose of his activities, rather, would be practical and intended to enable the United Nations to act in a timely fashion.
