Book excerpt: In Volume 107 of Terrorism: Commentary on Security Documents, entitled "U.N. Response to Al Qaeda", new General Co-Editor Kristen Boon covers the history that started with U.N. Security Council Resolution 1267 in 1999 and that continues today. In that document, the United Nations established sanctions against any individuals or organizations financially supporting those two terrorist organizations or Osama bin Laden. With her expert commentary on all documents flowing from that resolution, Boon traces the unfolding fate of those sanctions, from the amending resolutions that expanded the sanctions' purview to the provision of a notice period for targeted parties to specific countries and regions' implementing legislation to court challenges claiming that the sanctions violate the targeted parties' human rights. No other book offers what this volume does: an expert guide to the U.N.'s first effort at sanctioning a select group of parties rather than a broad, comprehensive category of unspecificed people.
