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.

In June 2014, African Heads of States and Governments adopted the Protocol on the Amendments to the Protocol on the Statute of the African Court of Justice and Human Rights in Malabo, Equatorial Guinea. The Malabo Protocol seeks to expand the jurisdiction of the African Court to international and transnational crimes. This development raises fundamental issues of jurisdiction, capacity, political will and regional complementarity in the fight against impunity in the African continent. The paper interrogates the role of Civil Society Organisations in the adoption and possible operationalisation of the Court in support of the efforts of the African Union to end human rights abuses and commission of international and transnational crimes within the continent.

The principle of universal jurisdiction is a unique ground of jurisdiction in international law that may permit a State to exercise national jurisdiction over certain crimes in the interest of the international community. This means that a State may exercise jurisdiction regarding a crime committed by a foreign national against another foreign national outside its territory. Such jurisdiction differs markedly from the traditional bases of jurisdiction under international law, which typically require some type of territorial, nationality or other connection between the State exercising the jurisdiction and the conduct at issue. Due to the definitional and other ambiguities surrounding the universality principle, which has in its past application strained and today continues to strain relations among States at the bilateral, regional and international levels, this paper successfully made the case for the inclusion of “Universal Criminal Jurisdiction” as a topic in the long-term programme of work of the International Law Commission during its Seventieth Session (2018). It was submitted that taking up a study of this timely topic, which has been debated by the Sixth Committee of the UN General Assembly since 2010, could enhance clarity for States and thereby contribute to the rule of law in international affairs. It will also serve to continue the ILC’s seminal contributions to the codification and progressive development of international criminal law.
