The UN General Assembly established the International Law Commission (“ILC”) in 1947 to assist States with the promotion of 1) the progressive development of international law and 2) its codification. The ILC’s first assignment from the General Assembly was to formulate the Nuremberg Principles, which affirmed the then radical idea that individuals can be held liable for certain international crimes at the international level. Since then, the ILC has played a seminal role in the development of modern international criminal law. In 2017, the ILC adopted on first reading a draft convention aimed at the prevention and punishment of crimes against humanity which it transmitted to States for comments. The draft treaty will help fill the present gap in the law of international crimes since States criminalized genocide in 1948 and war crimes in 1949, but missed the opportunity to do so for crimes against humanity. This Article examines the first reading text using the lens of the ILC’s two-pronged mandate. Part II explains how the ILC can take up new topics and the main reasons why it decided to propose a new crimes against humanity convention. Part III discusses positive features of the draft convention, highlighting key aspects of each of the Draft Articles. Part IV critiques the ILC draft treaty focusing on inconsistencies in the use of the ICC definition of the crime, immunities, amnesties, and the lack of a proposal on a treaty monitoring mechanism. The final part draws tentative conclusions. The author argues that, notwithstanding the formal distinction drawn by the ILC Statute between progressive development, on the one hand, and codification, on the other hand, the ILC’s approach to the crimes against humanity topic follows a well settled methodology of proposing draft treaties that are judged likely to be effective and broadly acceptable to States rather than focusing on which provisions reflect codification and which constitute progressive development of the law. It is submitted that, if the General Assembly takes forward the ILC’s draft text to conclude a new crimes against humanity treaty after the second reading, this will make a significant contribution to the development of modern international criminal law.

The concept of control has permeated various disciplines of public international law, most notable international criminal law, international humanitarian law, international human rights law and the law of statehood as well as the law of responsibility for states and international organizations. Often this notion of control has been used to extend the regular parameters in these disciplines to capture more extraordinary situations and apply the same rules originally developed within areas of law, such as the application of the laws of war to occupation, the rules of human rights treaties to extraterritorial situations or state responsibility to non-state actors. This article will examine this notion of control in all its facets in international law while also addressing some of its controversies and disagreements in the jurisprudence of international institutions, which have utilized this concept. The article will then provide an overview of its uses in international law as well as its overlap from one discipline to another with a view of providing some overarching observations and conclusions.

The forced displacement of civilian populations is an issue of significant global concern and a subject of extensive legal debate. In international criminal law, forced displacement is criminalized by a complex network of distinct but overlapping offences. These include the Crimes Against Humanity of deportation, forcible transfer, persecution and other inhumane acts, and the grave breach of the Geneva Conventions of ‘unlawful deportation or transfer’. International courts and tribunals have been inconsistent in the adoption of these crimes in their statues and in their subsequent interpretation, making it all the more difficult to distinguish between them. The jurisprudential history of these crimes is lengthy and not without controversy, highlighted by inconsistent judicial approaches. In this article, we offer a critical jurisprudential history of these displacement crimes in international criminal law.
In particular, we focus on the case law emanating from the International Criminal Tribunal for the former Yugoslavia, a court that comprehensively addressed crimes associated with ethnic cleansing, a characteristic feature of that conflict, with the result that displacement was a central focus of that court. We set out our jurisprudential history in chronological order, beginning with the earliest inceptions of displacement crimes at the ICTY and then tracing their development toward the establishment of a consensus. Our hope is that the article sheds light on the development of these offences, informs future debate, and acts as a useful template for those seeking to understand how these crimes may have a role to play in future international jurisprudence.
