This dissertation analyzes the German-French initiative at the United Nations aiming at an international convention against human reproductive cloning. It outlines the status quo of the international debate regarding a regulation of human cloning, including the scientific procedure of human reproductive and therapeutic cloning and its risks and promises from the perspective of science. It also analyzes the current legal framework at the international level, followed by a case study of the law in jurisdictions particularly involved in the UN initiative. Finally, a report of the negotiations (2001-2005) that Germany and France had sparked at the UN General Assembly is detailed. It focuses on the deep divisions over whether not only reproductive cloning - which the world community rejects unanimously - should be prohibited, but also therapeutic cloning, or whether the latter should merely be subject to controls. The General Assembly finally acknowledged that the controversy was for the time being shelved and resorted to a legally non-binding political Declaration on human cloning. As a matter of fact, this decision put the German-French initiative towards a legally-binding instrument to an end. The dissertation is taking stock of developments so far and investigates the strong and the weak points of the German-French initiative, in order to then make brief suggestions on how to move ahead in order to pass legally binding international laws on human cloning.
