In a relatively short period of time, the International Law Commission has accomplished the impressive task of drafting and adopting the text of the Draft Articles on Prevention and Punishment of Crimes against Humanity. The Draft Articles circulated to states are promising. However, a number of substantive amendments appear to be necessary if the Draft Convention is to become a powerful tool “to put an end to impunity for the perpetrators of these crimes and thus to contribute to the prevention of such crimes”, as stated in the Preamble. Moreover, in order to avoid the rapid ossification of the new potential treaty, it is advisable for the articles to reflect the most significant developments in international law, and also allow for future progressive developments in the law, instead of reflecting a lowest common denominator acceptable to all states. This article suggests some revisions to existing provisions, new provisions which may make the text much stronger and finally identifies some important omissions which should be fixed by states at the time of adopting the Draft Convention.

The Western Europe and Other Group of states have a long history with crimes against humanity. They were pivotal in the juridical creation of this concept, in launching prosecutions in both international and national courts, and in formulating the modern definition of the crime. However, some members have expressed concerns around the International Law Commissions Draft Articles on the Prevention and Punishment of Crimes Against Humanity. This article provides a summary of the history of crimes against humanity in the Western Europe and Other Group of states, as well as the current status of crimes against humanity in their legal systems. It argues that although these states have successfully incorporated crimes against humanity into their legal frameworks, it would be beneficial for them to embrace the proposed Crimes Against Humanity Convention.
