Unanimously adopting resolution 1859 (2008) under Chapter VII of the United Nations Charter, the Council also extended the task of the International Advisory and Monitoring Board in overseeing the Fund for the same period. The Council decided that those decisions would be reviewed upon request by the Government of Iraq or no later than 15 June 2009, while encouraging the International Monetary Fund (IMF) and the World Bank, as members of the International Advisory and Monitoring Board, to brief the Council in January 2009.
