The Rome Statute of the International Criminal Court allows the United Nations Security Council to postpone prosecution under certain circumstances (according to article 16). When Africans claimed last year that the threatened prosecution of Sudanese President El Bashir should be suspended, many told them to invoke article 16. Even the Prosecutor has referred to article 16 in his statements on the relationship between peace and justice, suggesting that the Court should leave 'the interests of peace' to the Security Council.
This is a trap for the Court, and its defenders, however. Telling countries in Africa that their problems can be solved by the Security Council doesn't really sell very well. Sometimes Europeans and Americans forget that not everybody thinks that the Security Council is the place to which to turn for a solution to a problem. And so South Africa has answered this with a proposed amendment to article 16 that would let the General Assembly, and not just the Security Council, suspend a prosecution. It doesn't stand a chance of adoption, but it makes a good point. For a nice discussion of this, see a recent article by South African academic Chris Gevers: http://www.businessday.co.za/articles/Content.aspx?id=90453.
